Cold forging of Thermal Solutions Copper Liquid Cold Plates is a technical process for forming and forging profiles below the recrystallization temperature (in general, normal temperature). Cold forging materials are mostly aluminum and some alloys, copper, and some alloys with low deformation resistance and good plasticity at room temperature. Cold forging can cause work hardening (strain hardening) of the profile during processing, which can increase the strength and hardness.
The cold forging process is widely used by radiator manufacturers in the production of Thermal Solutions Copper Liquid Cold Plates, light source radiators, and LED radiators. PETROL STEEL is an earlier manufacturer of cold forging radiators and has accumulated rich experience in cold forging processes. In addition to the production of general light source radiators, PETROL STEEL has reserved the technology to manufacture high-power cold forging radiators to solve the problems of poor thermal conductivity of die-cast microchannels and the high cost of machine-added microchannels. It has begun to be applied to high-voltage inverters, wind power converters, and motors. Controllers and other water-cooling solutions.
The characteristics of PETROL STEEL vacuum diffusion welding for Thermal Solutions Copper Liquid Cold Plates: Diffusion welding has no solder, and the welding strength is high. At the same time, the secondary welding has no influence on the core weld; High and low-temperature resistance; Low leakage rate, high compactness, and high heat exchange efficiency; Different types of materials can be welded; It can weld workpieces with complex structures and large differences in thickness; The heating is uniform, the weldment is not deformed, and no residual stress is generated so that the workpiece maintains a high-precision geometric size and shape.
