FAQs About aluminum extrusion heat sinks


Aluminum heat sinks extrusion can provide a heat management process used by PCB and Circuit boards. This helps to grant a specific merge between horizontal and vertical cooling. There are different customized forms and thicknesses which are achieved easily. Are you confused about what aluminum extrusion heatsink is all about? Then stick to this piece, as answers to your questions will be answered.

Commonly Asked Questions on Heat Sinks

1. What is a Heat Sink?

Extruded heat sinks are mostly used for the management of thermal these days. They are created by using steel and pushed hot billets made from aluminum which creates the end shape. The basic aluminum type available is 6063-T5. There are other 6XXX alloys that can also be used as desired.

2. How Could You make use of an Aluminum heatsink?

First, aluminum has various thermal conductivity levels. Having a high thermal conductivity rate would increase how efficient it is at sending heat. This is a common metal used for heat sinks. It has a thermal conductivity rate of 235 watts per Kelvin per meter (W/mK).

3. Why do they make heat sinks out of aluminum?

It is cost-effective, simple to make, and lightweight. This is why it is a great choice for different heat sinks. It can easily move at a rate close to copper. This reduces the distance of conducting and moving heat from the source.

4. How are these aluminum heat sinks designed?

Aluminum heat sinks are usually made by milling, skiving, casting, and extrusion. Because of the high sink properties, copper has antimicrobial resistance, biofouling resistance, corrosion resistance, and thermal conductivity.

5. Do an aluminum extrusion heat sink need fans?

Different heat sinks have dense fins. These need a fan to get mounted on a cooler directly. If you have a heat sink that uses heat pipes (which are tubes of copper running through its fins), these are designed for use with a fan. It is easy to test if your heat sink can work with a can or not.

6. How hot can a CPU get in the absence of an aluminum extrusion heat sink?

It would get to around 80-100C before it pops in seconds. The PC would not POST. Using a heatsink, you could get some life from it. The bare processor would pop quickly.

7. How can I select an aluminum extrusion heat sink?

Normally, the list below is the main Heat Sink Design Consideration factor if you need a great design and selection of Aluminum Heat Sinks.

You should check the following;

  1. Cost of system
  2. Size of the product
  3. The IP rating of the system
  4. The range of its operating temperature
  5. Convection availability options for cooling
  6. Requirements for insulation and isolation.

8. Is a bigger aluminum heat sink better?

Having a large heatsink would mean it can dissipate heat faster. Having a large base plate surface area would mean the speed of sending heat from the CPU down to the pipes would allow enough room for mounting error materials. That would increase the rate of thermal solutions production. Copper has twice the thermal rate of conductivity than aluminum and could create a better heat sink.
