The technology and production process of custom heat sink varies in design, which will affect the heat dissipation effect of the final aluminum profile custom heat sink. Therefore, custom heat sink design is particularly important as the first step in heat sink manufacturing.

 

As a heat dissipation tool with high heat dissipation efficiency, the aluminum profile custom heat sink is widely used in the electronics, electrical appliances, and lighting industries. Different custom heat sink manufacturers have different technical processes and refer to different production standards. The aluminum profile heat sink will also have good or bad heat dissipation effects. Therefore, to pursue better heat dissipation effect, how to design the custom heat sink?

Bottom design of custom heat sink

The fins are usually considered to be the key of heat dissipation. In fact, the heat sink at the bottom is also a part that cannot be ignored in heat dissipation. The bottom design of the custom heat sink should adhere to the principle of gradually thinning from the heat source part to both sides, which is to ensure that the heat absorbed by the heat source part can be quickly transferred to the surrounding thinner parts to achieve high-efficiency heat dissipation. 

 

Fin design of custom heat sink

Designing the heat sink in the shape of fins is not only to increase the contact area with the heat source to absorb more heat, but also to increase the contact area between the heat sink and the air so that the heat can be dissipated into the air faster.

 

 

Aluminum extrusion technology

It is obvious that the heat sink has extremely high requirements in shape design and dimensional accuracy. The heat sink must be error-free during the molding process in order to achieve the expected heat dissipation effect. Aluminum extrusion is a part processing method that applies strong pressure to the aluminum alloy material placed in the mold cavity to cause directional deformation of the aluminum alloy, thereby obtaining the required cross-sectional shape, size and certain mechanical properties.

 

 

 

Surface treatment

The effect of ordinary aluminum profile heatsinks on radiation heat dissipation is not good, and anodizing is used to form an oxide film on the surface of aluminum profile heatsinks to enhance the heat radiation ability of the heat sink and make the heat dissipation effect of the heat sink more outstanding.
