Cold Forging Heat Sink Parts

Cold Forging Heat Sink parts are heat sink components manufactured by cold forging, which plastically deforms metal at room temperature or near room temperature. Compared with hot forging, cold forging can improve the hardness and strength of the material while maintaining good dimensional accuracy and surface finish.Cold forging Heat Sink parts made by cold forging have the advantages of high precision, good mechanical properties and material saving, which can effectively improve heat dissipation performance and are widely used in engine control units (ECUs), battery management systems (BMSs) and base stations to ensure the normal operation of equipment and extend service life.

Commonly used materials for cold forged heat sink components mainly include aluminum (such as AL1070 pure aluminum) and copper and their alloys. These materials have the following advantages:

Good thermal conductivity: Aluminum and copper are both excellent thermal conductive materials, which can quickly transfer heat from the heat source to the heat sink surface, thereby improving heat dissipation efficiency.

Lightweight and high strength: Aluminum and copper have relatively low density but high strength, which enables cold forged heat sink components to withstand greater mechanical stress while maintaining lightweight.

Good plasticity: Aluminum and copper have good plasticity at room temperature and are easy to form complex shapes and structures through cold forging processes.

Corrosion resistance: After proper surface treatment, aluminum, copper and their alloys can resist a variety of corrosive environments and extend the service life of heat sink components.

The thickness of cold forged heat sink components varies depending on the specific application, but factors such as heat dissipation efficiency, structural strength and material cost are usually considered during design. Tightness detection is a key link in ensuring the quality of heat sink components. Commonly used detection tools include:

Vernier caliper: used to measure the thickness, diameter and other dimensions of heat sink components to ensure that they meet design requirements.

Micrometer: A more accurate measuring tool suitable for accurate measurement of the tiny dimensions of heat sink components.

Coordinate measuring machine: It can measure the three-dimensional dimensions and shape of heat sink components to ensure that their position and posture in space are accurate.

Hardness tester: It is used to detect the hardness of heat sink components to evaluate their strength and wear resistance.

Magnifying glass and microscope: It is used to observe the surface morphology and microstructure of heat sink components to check whether there are defects such as cracks and pores.

Tightness detection usually involves measuring and inspecting the assembly gap, mating surface and other parts of the heat sink components to ensure that they can fit tightly during use to avoid problems such as heat leakage and mechanical loosening.

Surface treatment of cold forged heat sink components is of great significance to improve their heat dissipation efficiency, corrosion resistance and aesthetics. Common surface treatment methods include:

Anodizing: By forming a dense oxide film on the surface of aluminum, the corrosion resistance and hardness of the heat sink components are improved. At the same time, the anodized film can also be used as a heat dissipation surface to improve heat dissipation efficiency.

Sandblasting: Use compressed air to spray abrasive particles onto the surface of the heat dissipation component at high speed to remove surface dirt and oxide layer, forming a uniform and rough surface, which is conducive to heat dissipation and increasing coating adhesion.

Electroplating: A layer of metal or alloy is plated on the surface of the heat dissipation component to improve its corrosion resistance and aesthetics. Commonly used electroplating materials include zinc, chromium, nickel, etc.

Spraying: Spray the paint evenly on the surface of the heat dissipation component to form a protective film to improve its corrosion resistance and aesthetics. At the same time, some paints can also be used as heat dissipation surfaces to improve heat dissipation efficiency.

Wire drawing: A series of parallel fine lines are formed on the surface of the heat dissipation component by mechanical or chemical methods to increase the roughness and beauty of the surface.
