Cold forging heat sink is a kind of heat sink made by cold forging process, ‌ has high efficiency heat dissipation and excellent corrosion resistance, ‌ is widely used in vehicle headlights and other fields. ‌

The main features of cold forging heat sinks include: ‌

Integrated forming: ‌ base plate (‌ bottom plate) ‌ and fin integrated forming, ‌ no gap, ‌ to ensure that heat can be directly transferred to the heat dissipation fin, ‌ improve heat dissipation efficiency. ‌

Three-dimensional air intake design: ‌ air intake direction is three-dimensional air intake, ‌ compared with the traditional two-dimensional air intake design, ‌ can better adapt to the environment, ‌ to obtain better heat dissipation effect. ‌

Heteronormative structure: ‌ mold casting, ‌ on the back of the substrate there is a heteronormative structure, ‌ better combined with the heating element, ‌ improve the heat dissipation effect. ‌

Material and appearance: ‌ aluminum is usually used as the material, ‌ surface can be anodized, ‌ smooth and bright, ‌ can also be sprayed according to the need for different colors of anodic sandblasting (‌ such as silver, ‌ white, ‌ black, etc.) ‌. ‌

Water cooling plate design: ‌ pipes as part of the water cooling system, ‌ its structure design including the selection of materials (‌, such as aluminum, copper ‌, ‌ stainless steel ‌ among them the most widely used aluminum) ‌, ‌ sealing way (‌ if O - Ring seal and welding) ‌, ‌ to ensure inside limited space through reasonable decorate flow effectively reduce the thermal resistance of cold plate, ‌ satisfies the requirement of heat dissipation performance. ‌

The application fields of cold forging heat sink mainly include the heat dissipation of vehicle headlights, ‌ by quickly distributing the heat emitted by the headlights, ‌ to prevent the lamp or other lamp components from overheating damage, ‌ to extend the service life of the headlights. ‌ at the same time, ‌ it can also improve the working efficiency and brightness of the headlights ‌ so as to improve the safety of night driving. ‌ In addition, the use of ‌ cold forging heat sink can also enhance the beauty of the lights, ‌ improve the decoration of the vehicle.
