Product Introduction
Product Description
Cold forged heat sinks are a type of heat sink that is manufactured using metal cold forging technology. This process is used to create high-strength and high-precision parts. Unlike traditional hot forging processes, cold forging is carried out at room temperature, eliminating the need to heat metal materials to high temperatures. The resulting parts have higher density, strength, wear resistance, and surface quality.

A. The LED cold forging COB heat sink is constructed from pure aluminum, with the blade able to be 0.8mm thick to maximize the heat radiation surface area of the product. The integrated heat sink, with the same volume and shape, can be utilized for dissipating heat from higher power products, and is lighter in weight, resulting in reduced transportation costs.
B. The thermal conductivity of the same integrated die-casting product material is only 96m. K, and the blade should not be too thin to increase the weight of the product. The surface of die-casting products cannot be anodized, but can only be painted, which will affect heat dissipation.
C. The thermal conductivity coefficient of automotive aluminum profiles is only 136-196m. K, and the split heat sink of aluminum profiles has a significant impact on heat conduction, resulting in only about 60% of the heat dissipation capability of the same type of integrated products. When two cold extruded one-piece heat sinks of the same volume and shape are used on products with the same power, the one-piece heat sink temperatures are approximately 5-6 degrees lower, significantly extending product life.
