2022-05-17 10:54:19

Extruded aluminum heatsinks are popular choices for PC builders. Many have questions about them, though. In this article, I provide 21 extruded heatsink FAQs.


What is an Extruded Aluminum Heatsink?

An extruded aluminum heatsink is a type of heat sink that uses a thin, profiled shape to dissipate heat. The profile can be flat or curved and is typically used in electronic devices such as computers and laptops.

An extruded aluminum heatsink is made by using a die casting machine to form aluminum into its desired shape. The material is then machined with precision tools to ensure a tight fit between components. The final product is an extruded aluminum heatsink with an effective surface area for cooling purposes.

The most common type of extruded aluminum heatsink is known as a finned extruded aluminum heatsink.

Finned Extruded Aluminum Heatsinks

A finned extruded aluminum heatsink is a device composed of several thin fins attached to a solid base that is made from one continuous piece of aluminum. The fins are connected together at their base by small tabs, which allow them to be easily removed from the base for maintenance or replacement if necessary.



What is the Extruded Aluminum Heatsink Made Of?

Extruded aluminum heatsinks are made from aluminum ingots that are melted down and then extruded through a die. The extrusion process creates an extruded aluminum heatsink with the desired cross-sectional shape, which is then cut to length, drilled, and machined to size.

The material used to make the extruded aluminum heatsinks is called 1100 series aluminum alloy, which is an alloy of 99% pure aluminum and 1% copper. This alloy has excellent mechanical properties, including high strength, excellent corrosion resistance, and good fatigue resistance.

Aluminum alloys of this type have good thermal conductivity, which makes them suitable for use in a range of applications where heat dissipation is required. For example, they are often used in electronics cooling applications such as computer processors or power supplies.


What is the Function of the Extruded Aluminum Heatsink?

The function of an extruded aluminum heatsink is to provide a surface for the heat generated by a heat source to be transferred to a heat sink. The heat sink is then cooled by air or water, which transfers the heat away from the device.

A heatsink is a large block of aluminum, copper, or steel that is attached to a semiconductor chip using thermal grease and thermal pads. The purpose of this device is to dissipate heat away from semiconductor chips as they operate at high temperatures. This helps maintain their operational efficiency while also reducing their risk of failure due to over-heating.


Where Are Extruded Aluminum Heatsinks Used?

Extruded aluminum heatsinks are used in a wide variety of applications, including:

Computer components. Computer case and video card manufacturers use extruded aluminum heatsinks to keep their computer components cool. The most common type is the heat sink with a fan attached, which blows air over the fins to increase surface area and speed up heat dissipation.

Electronics. These are used on any electronic device that generates heat during operation. They're often found on power supplies, amplifiers, and other devices that require cooling to prevent damage from overheating.

Automobiles. Automotive engineers use extruded aluminum heatsinks to keep their vehicles' engines from being damaged by excessive heat buildup during operation. They're also used for air conditioning units, which generate a lot of heat when running at full capacity.


Why Use an Extruded Aluminum Heatsink?

There are many different types of aluminum heatsinks available on the market, but extruded aluminum heatsinks are some of the most popular.

The main reason for this is that they are cheaper and easier to manufacture than other styles. They also have a number of benefits over other types of heatsinks, including:

Lower weight – Extruded aluminum heatsinks are lighter than solid copper or brazed aluminum. This makes them ideal for use in mobile devices such as smartphones and tablets, where weight can be an important factor.

Lower cost – Because they are simpler to manufacture, extruded aluminum heatsinks cost less than other types of heat sinks. This makes them suitable for use in low-cost applications such as electronics projects, where cost savings can help keep costs down.

Higher thermal conductivity – Extruded aluminum heatsinks have a high thermal conductivity compared to other materials used in heat sinks, which means that they can transfer heat more quickly from one part of a device to another. This makes them particularly useful in applications where high temperatures need to be kept under control (such as servers).


What's the Best Shape for an Extruded Aluminum Heatsink?

There are many different shapes of extruded aluminum heatsinks. The most common is a rectangular block, but there are also trapezoidal, triangular, and circular variations. Each has its own advantages and disadvantages.

Rectangular Heatsinks

The most common extruded aluminum heatsinks are rectangular in shape. They're easy to manufacture, they're efficient at dissipating heat and they can be designed to fit into tight spaces. However, they can also be difficult to mount because they're not very flexible.

Trapezoidal Heatsinks

Trapezoidal extruded aluminum heatsinks are sometimes used when space is at a premium because they allow you to make a larger heatsink in a smaller area than you could with a rectangular design. However, they're more difficult to mount than rectangular ones because they don't have flat mounting surfaces on both ends as rectangles do. They also tend to be less efficient than rectangles at dissipating heat because their surface area is smaller compared to their volume — so if you have an application where heat dissipation is critical (such as an amplifier), this may not be the best choice for your needs.

The best shape for an extruded aluminum heatsink is a rectangular one.

The reason is that it allows the heat to be dissipated evenly over the entire surface of the device. If you have a square or round shape, then most of the heat will be concentrated in one corner of the device.

This means that it would be possible for your device to overheat and stop working due to overheating. This can cause serious problems with your computer hardware and may even lead to fire hazards.

So, if you want to ensure that your computer will run smoothly for years, it is important that you use an extruded aluminum heatsink with a rectangular shape so that it can dissipate heat evenly throughout the device


What Are the Benefits of Extruded Aluminum Heatsinks?

Extruded aluminum heatsinks are a great choice for any application that requires heat dissipation. They are available in a variety of shapes and sizes, with varying fin densities. The fins on extruded aluminum heatsinks are generally thicker than those on copper heat sinks, which makes them better suited for high-heat applications.

Benefits of Extruded Aluminum Heatsinks

1) Cost-Effective: Extruded aluminum heatsinks tend to be much less expensive than copper-based units, making them an excellent choice for cost-effective applications such as servers and other high-power devices.

2) Lightweight: Unlike copper heat sinks, extruded aluminum heatsinks are lightweight, which makes them easy to install in tight spaces or difficult areas where weight can be an issue.

3) Durable: Extruded aluminum heatsinks have a very long lifespan since they do not corrode or oxidize like other materials used in heat sinks (such as stainless steel). This means that you won’t need to replace your extruded aluminum unit as often as you would other types of heat sinks on the market today.


How Do I Buy an Extruded Aluminum Heatsink?

You can buy an extruded aluminum heatsink from a variety of places, including online and at your local hardware store. The most important thing is to make sure that the heatsink fits your needs and is made of high-quality materials.

When you're buying an extruded aluminum heatsink, there are a few things to keep in mind. The first is whether it's single or double-sided extrusion. Single-sided extrusion means that one side of the metal has been cut away, leaving two flat sides with holes for mounting hardware. Double-sided extrusion means that both sides have been cut away, leaving four flat sides with holes for mounting hardware.

The second thing to consider is the number of fins on your extruded aluminum heatsink: A fin is a raised ridge that runs along the length of the aluminum block. It helps increase airflow through the device and dissipate heat from components like CPUs or GPUs (graphics processing units).


How is an Extruded Aluminum Heatsink Different from a Bonded Fin or Skived Fin Heatsink?

A bonded fin or skived fin heatsink is a thin sheet of metal with fins stamped out of it. It’s then mechanically attached to a base that has the cooling fins machined into it. The heat is transferred from the base to the thin sheet of metal, where it is then dissipated into the air.

Extruded Aluminum Heatsink vs Bonded Fin or Skived Fin Heatsinks

The extruded aluminum heatsink is different because it’s made from a single piece of aluminum that has been stretched into a fin shape using high pressure and heat. After that, fins are stamped out of the extrusion using precision tools.

The reason why extruded aluminum is more expensive than bonded fin or skived fin is that it takes time and money to create an extrusion die for each size and type of heatsink needed for your specific application.

Is It Safe to Use an Extruded Aluminum Heatsink in My Product?

Yes, it is safe to use an extruded aluminum heatsink in your product! Extruded aluminum heatsinks have been used for decades by manufacturers worldwide without incident because they are designed to meet UL standards for safety. Extruded aluminum heat sinks must pass rigorous testing procedures before they can be sold in the U. S., which ensures that they will not catch fire or explode when they get hot enough.


How to Use the Extruded Aluminum Heatsink?

The extruded aluminum heatsink is an efficient solution for cooling electronic systems, especially high-power electronic devices. It is very easy to use, and it can be used in various types of applications. However, you should know how to use your extruded aluminum heatsink properly in order to get the best results from it.

The following are some tips on how to use the extruded aluminum heat sink:

1. Make sure that your system has enough airflow

2. Use thermal compound on the bottom of the heat sink

3. Mount the fan according to its specifications


How to Choose the Right Extruded Aluminum Heatsink for Your Application

Extruded aluminum heatsinks are one of the most common types of heat sinks used in electronic equipment, and they come in many different shapes and sizes. They are also relatively inexpensive and easy to manufacture, which makes them a good choice for many applications.

There are several factors to consider when choosing an extruded aluminum heatsink. One of the most important is the amount of surface area you need. This will determine which size extruded aluminum heatsink you need. Another factor is the type of material that you need to dissipate heat through conduction, convection, or radiation. Certain types of materials conduct heat better than others do, so this will also affect your selection process.

Some extruded aluminum heatsinks are designed specifically for use with certain types of chipsets or other electronic components that generate large amounts of heat during operation. These units may have special thermal interfaces or other features that allow for better cooling performance than standard units that do not have these features installed on them.

Choose the Right Extruded Aluminum Heatsink

Which Types of Extruded Aluminum Heatsinks Are Suitable for High-power Applications?

The selection of the type of aluminum heatsink is one of the most important aspects when designing a high power system. The fundamental difference between different types of extruded aluminum heatsinks is their thermal conductivity. This property determines how much heat can be transferred from one side of the material to another.

Aluminum heatsinks are a great choice for high-power applications.

Aluminum heatsinks offer several advantages over other materials. Aluminum is an excellent conductor, while also being relatively lightweight and inexpensive. These characteristics make aluminum heatsinks an excellent choice for high-power applications, especially when heat dissipation is a concern.

The main disadvantage of aluminum heatsinks is that they cannot dissipate heat as quickly as copper or steel can. This means that the use of aluminum heatsinks in high-power applications may result in greater operating temperatures. However, this can be mitigated by increasing the size of the aluminum heatsink (which increases its surface area).

The most common extruded aluminum heatsinks are made up of 6063-T6 aluminum alloy. However, some manufacturers also use 6061-T6 aluminum alloy if the application needs a stronger material.

The main difference between these two alloys is their strength, i.e., 6063-T6 has higher strength than 6061-T6. However, if you need a stronger material as your application requires more heat dissipation capability then you should go with a 6061-T6 extruded aluminum heatsink.


What is the Length of an Extruded Aluminum Heatsink?

Aluminum heat sinks are made of extruded profiles that are formed into various shapes and sizes. The two most common types of extrusion used in aluminum heatsinks are the square and round types.

The length of an extruded aluminum heatsink will depend on the profile that has been selected, but typically they range from 1 to 6 inches long.

The width of an extruded aluminum heatsink can range from 0.125 inches to 1 inch wide depending on the profile selected and the application for which it is being used.

The height of an extruded aluminum heatsink is usually 3/4 inch or less, but this again depends on the profile selected as well as other factors such as whether it is being used for mounting components or simply cooling them passively.

How Many Types of Extruded Aluminum Heatsinks Are There on the Market?

There are many different types of extruded aluminum heatsinks on the market. Here are some examples:

-Aerofoil-shaped heat sinks: these are the most common type of extruded aluminum heatsink, and they’re used in a wide range of applications. They’re typically made from extruded aluminum with fins that increase surface area and improve heat transfer to air or liquid coolants.

-Finned heat sinks: these have fins like aerofoil-shaped heat sinks, but they also have a greater number of them. This makes them more efficient at transferring heat away from electronic components.

-Solid copper core extruded aluminum heatsinks: these are like finned heatsinks, but they have a solid copper core instead of fins. This makes them more effective than finned heat sinks at transferring heat away from electronic components.


What is the Standard Length for Extruded Aluminum Heatsinks Produced Today?

The standard length for extruded aluminum heatsinks produced today is 12 inches (305mm). This is the most common size, and the most cost-effective.

The next size down is 10 inches (254mm). This site is a little more expensive than 12-inch heatsinks, but it can still be cost-effective when you use large quantities of heatsinks in a single design.

The smallest extruded aluminum heatsink we offer is 8 inches (203mm). This size is also called a "half-size" heatsink because it's half as long as the standard 12-inch extruded aluminum heatsink. This site is popular because it's cheaper than a full-size 12-inch extrude, and yet still provides plenty of surface area for heat dissipation from high power devices like CPUs and GPUs.

We don't offer 7-inch extrudes or smaller ones because they're not cost-effective for most applications. 7-inch extrudes are about 50% longer than half-sizes, so if you want to go smaller than 8 inches then it's usually better to use several half-sizes instead of just one full-size extrude.


Can Every Manufacturer Make an Extruded Aluminum Heatsink That I Want at Any Length?


Extruded aluminum heatsinks are made in many sizes and lengths. The choice is yours.

You can find extruded aluminum heatsinks in a variety of lengths from most manufacturers, but here are some guidelines:

- If your extruded aluminum heatsink must be cut to length, you should allow an extra 1/16" (1.6mm) per inch (25mm). This will make sure that your end product looks good, with no nicks or dings.

- If you need custom colors or special finishes, we recommend using a laser cutting process rather than sawing. This will ensure that your extruded aluminum heatsink looks great!


What Does an Extruded Aluminum Heatsink Look Like Before It's Finished?

Extruded aluminum heatsinks are a popular choice for DIY builders and manufacturers because they're easy to work with, lightweight, and cost-effective. They're also available in a wide range of sizes, shapes, and thicknesses.

However, one question remains: what does an extruded aluminum heatsink look like before it's finished?

An extruded aluminum heatsink is a piece of metal that has been rolled into a tube shape and then flattened out like a pancake.

The extrusion process is used to make many products, including pipes, tubing, and cylinders. In the case of heatsinks, extrusion allows manufacturers to make custom-sized heatsinks that can be cut to fit any computer case or other enclosure.

An extruded aluminum heatsink is made from raw material in a manufacturing facility with specialized equipment. The first step is to take large sheets of aluminum alloy and roll them into long tubes called billets. The billets are then flattened out into sheets called blanks. The blanks are then cut into smaller shapes, which include mounting brackets and fins for heat dissipation purposes.


If you've ever wondered how extruded aluminum heatsinks are made, here's a quick look at the process:

1. The raw material is first to cut into the desired length using a saw.

2. Next, the sheet metal is bent into a rough shape using mechanical rollers or presses. This step can be done manually or by computer-controlled machines that bend the sheets into predetermined shapes.

3. Once the sheets are bent into their final shape, they're drilled to create mounting holes for screws or bolts (depending on whether they're going to be mounted directly onto a heat source).

4. After drilling holes in the aluminum heatsinks, they're cleaned with chemicals (such as sandblasting) so that any dirt or debris left behind doesn't interfere with the soldering process later on in the manufacturing process


What's the Difference Between an Extruded Aluminum Heatsink and a Brazed Fin?

The main difference between an extruded aluminum heatsink and a brazed fin heatsink is that the extruded type of heatsink is composed of solid aluminum blocks. This makes them very strong and able to withstand high temperatures. However, they are not as efficient as brazed fin heatsinks because they are not designed specifically for heat dissipation.

The brazed fin type of heatsinks is more efficient than extruded types because they have fins on the top surface that increase the surface area for heat transfer. This allows more heat to be transferred from the CPU to the cooling system and away from the device as quickly as possible.

Another difference between these two types of heat sinks is that you can use special thermal grease to attach them to your computer components. You can also purchase thermal pads that will help improve the overall efficiency of your computer's cooling system.


Does the Length of an Extruded Aluminum Heatsink Affect Its Price?

The length of the extruded aluminum heatsink you purchase does not affect its price.

The size of the heatsink determines its application and performance, but this does not affect its price. In fact, the size of an extruded aluminum heatsink is independent of its cost. The larger the extruded aluminum heatsinks that you buy, the more units you can get per dollar spent.

You can determine the size of an extruded aluminum heatsink by measuring its length, width, and height. Some manufacturers list these measurements on their websites or on their product labels. You can also measure them yourself using a ruler or tape measure and compare them to your computer case specifications or model type.


Which One is Better in Terms of the Extruded Aluminum Heatsink and Cast Aluminum Radiator?

In terms of fin design, the extruded heat sink has better surface contact with the CPU than the cast aluminum radiator. This means that it will perform better in that particular aspect.

However, in terms of weight and size, the cast aluminum radiator wins hands down. It’s lighter and smaller than its extruded counterpart.

The only place where extruded heatsinks can compete with cast aluminum radiators is in terms of performance/wattage ratio. In this case, you would have to consider other factors such as price and noise level before making your decision on which one to buy.
