| Abstract: | Finite element analysis is established on the thermal contact resistance between power Mosfet and heatsink.A method is put forward to make a simulation of surface asperities and further research on the main factor of thermal contact resistance is carried in this paper.A relationship between thermal contact resistance and surface asperities is attained.The other factors on thermal contact resistance are also analysed.This method saves design cost and has certain guiding significance on Mosfet and heatsink design. |
