Abstract

Abstract:

In order to solve the problem of difficult steadying heat dissipation new demand for charging pile, which is caused by the increasing output power, complex internal structure and poor outdoor working environment, thermal analysis is highly necessary. This paper takes 150kW DC charging pile for research object, the thermal characteristic model of DC charging pile is established. The flow field and temperature field in the forced air cooled charging pile are simulated by finite volume method. At the same time, the ventilation and cooling scheme is optimized. The heat dissipation effect of charging pile under actual ventilation and improved ventilation scheme is compared and analyzed. The improved ventilation scheme is more favorable to the system heat dissipation by simulation analysis. Further more, the influence of the fan volume and the output power on the temperature field of the charging pile is studied. The results show that the improved ventilation optimization scheme is more conducive to reducing windage resistance and accelerating system heat dissipation, and provides theoretical guidance for the development of DC charging pile.

Key words: Charging pile, finite volume method, flow field, temperature field, thermal simulation
