Power device cooling has an important effect on the performance and dependability of the whole electronic equipment. In this paper, the structure layout of an airtight cabinet is optimized, and a structural style beneficial to the power device cooling is designed. Then the thermal simulation of the overall cabinet is carried out by means of the CFD software Icepak. The simulation results show that the cooling method of forced convection can control the final temperature of the main power device below 85 degree, which is acceptable in view of stable working.
