Custom Heat Sink With CNC Machining

Custom heat sink manufacturer

Activities

Extrusion, CNC machining, and anodized

CNC machined heat sinks allow manufacturers to get complex heat sink designs made that would otherwise be impossible. A custom heat sink is going to be made precisely according to the design specifications of the client. Since each electronic product has its own heat dissipation needs some equipment can’t utilize commercially available heat sinks. Therefore a custom heat sink is the only way to meet the complex design needs of certain product.

Custom heatsink design

MK CNC Parts specializes in producing machined parts using our state of the art machinery. There is no heat sink design too complex for our engineers to make. Whether you are looking for a specific custom heat sink design for electronics, heavy duty machinery, LED lights or computers MK CNC Company has you covered. Customized heat sinks made through CNC machining can be made out of any material you want. However we mostly use aluminum or copper to make highly efficient heat sinks using CNC machining techniques.
Benefits of Custom Heat Sinks Using a custom made heat sink has many advantages for both the electronics they are installed in as well as the manufacturer. Here are some major benefits of using custom heat sinks: Accurate design: If you have very specific design requirements then getting a customized heat sink made is the only way to meet your requirements. While there is pre made cm4 heat sink designs available they are usually not limited in terms of design options.

A customized heat sink can be made into any size or shape and can have features that optimize heat dissipation.
Better heat dissipation: Since a cm4 custom heat sink is made precisely to make full use of the design and space available inside your product it can cool the equipment better. If your electronic produce more heat by design then you will have to go with a customized heat sink design.
Custom heat sink designs are only achievable with the help of CNC machining techniques.
Freedom to choose your desired material: If you are trying to get your heat sink made in a specific material then you may not find it in wholesale market. MK CNC factory can make heat sinks in a wide range of materials including various alloys of copper and aluminum. Our heat sink machining experts have vast experience working on a wide range of heat sink materials.
Every material is going to have its own distinct thermal conductivity. Our custom laptop heat sink manufacturing services allow you to pick a metal with the desired thermal conductivity. When you combine a metal with correct conductivity with a well designed fin layout you get maximum heat dissipation.

Design Considerations For Custom Heat Sinks
Our engineers make the process of manufacturing a custom heat sink simpler than ever. However designing a custom cm4 heat sink requires careful consideration and calculations.
Material: The metal you choose should be able to move heat away from the circuit or chip at the correct rate.
The material of the custom heat sink also determines how difficult it is going to be for the CNC machine to cut and shape. Lastly material of the heat sink effects how well it can resist corrosion. So you should always choose the right material when designing a radiator.
Fin size and configuration: Heat sinks come in a wide range of fin shapes however straight fins and pin fins are two of the most commonly used designs. The size and configuration of the fins affects their ability to dissipate heat.
Surface finish: Surface finish you pick for your customized heat sink will directly affect its corrosion resistance. The great thing about CNC made heat sinks is that you get more surface finish options to choose from.
The type of surface finish you use will also affect the thermal conductivity of the heat sink. Certain surface finishes can transfer heat better than others so you should take surface finish into consideration when designing a heat sink.
Mounting mechanism: Heat sinks can be mounted using various mounting mechanisms and there is no one size fits all method. So you will have to choose a mounting mechanism based on the space availability, size, and orientation of the heat sink.

It is important to keep in mind that the mounting mechanism you choose shouldn’t increase the thermal resistance of the heat sink. We can help you manufacture heat sinks that can support any mounting mechanism to fit your needs.
Types of Materials Used in Manufacturing Custom Heat Sinks
Heat sinks are always made out of metals because of their ability to absorb and move heat quickly. Not to mention metals can withstand frequent heating and cooling that every heat sink has to go through. Here are some common types of materials used for making custom heat sinks.
Aluminum: There is no material more commonly used for making heat sinks than aluminum. Certain grades of aluminum including 6061 and 6063 are ideal for making heat sinks because they have high strength and thermal conductivity.
The great thing about aluminum is that it allows you to manufacture affordable heat sinks. Not to mention aluminum is a soft metal making it easier to machine using CNC. Copper: Copper has a very high thermal conductivity and it has a distinctly high corrosion resistance. Therefore copper is also used as a material for making heat sinks.
However unlike aluminum copper is a costly metal. Not to mention copper heat sink machining can be a challenge.
How to choose the right heat sink for your electronics devices?
Determine the thermal requirements of your electronic device and make sure the heat sink can meet them.
Make sure that the heat sink has enough air flow available if there isn’t ample air flow you may need to combine the heat sink with a fan.
Components that produce more heat will require a larger heat sink to keep them cool. Make sure you choose the right sized heat sink to cool down the device.
Make sure you are aware of the thermal resistance of a heat sink so that you can compensate for it using more fins or a larger surface area.
