Application of Micro Capillary Groove Radiator to Electric Vehicle Power-Control Unit

Abstract:

According to the structural characteristics of the controller and micro-groove heat sink technique, a new cooling system was designed for high power control unit of electric vehicles. And an experimental comparison on the radiating effect of forced air cooling, micro capillary groove radiator and their combination was then carried out. The experimental results showed that when compared with air-cooling method, the higher the power is, the more significant the heat dissipation effect is. The air cooling unit alone cannot meet cooling requirements when the heating power reaches 30 watts, with temperature exceeding the allowable ceiling for power devices. The strong heat removal ability of micro capillary groove radiator has a better effect for diminishing local overheating of IGBT, and it’s more applicable to cooling conditions of large heat flux.
