The UTHP was especially suitable for the heat dissipation of electronic equipment in narrow space. Thus it could be directly attached to the surface of the electronic components to cool the heat source. However, few researches reported on the application of UTHPs to the heat dissipation of the DC EV charging piles. Fig. 1.
The heat dissipation performance was evaluated by the peak temperature and temperature uniformity on the chip surface. According to the simulation results, the following conclusions can be drawn: UTHPs could significant enhance the heat dissipation capacity of the charging module.
The construction of the charging pile, which was called as the "gas station" of EV, developed rapidly. The charging speed of the charging piles was shorted rapidly, which was a challenge for the heat dissipation system of the charging pile.
