Selection of Radiators in Power Electronics and Analysis of Heat Dissipation

Abstract

People have attached increasing importance to the heat generated by power in power electronics during the production process in the field of industrial production at home as China’s science and technology rapidly makes progress in recent years. The operation of power electronic devices, due to the effects of resistance and voltage in the circuit, generates a certain amount of heat that will have a certain impact on the operation process of the entire power system. This essay, first and foremost, analyzes the heat circuit and heat group that cause power electronic devices to generate heat, and then the heat dissipation design of power electronic devices. Finally, detailed analysis on the current cooling methods and cooling effects commonly used in power electronic devices are made in accordance with the real conditions.
