According to the plasticity of the profile (aluminum or aluminum alloy) , the machining principle of the shoveling radiator makes use of the characteristics of the shoveling process in one-step forming, it can keep the original heat conduction efficiency of the profile, and also can achieve higher density and larger size production requirements to improve the heat dissipation performance. It can be used in all kinds of high-power motors, such as solar inverter, wind power converter, medium-high voltage transformer, power battery pack, etc. .
