The charging speed of the charging piles was shorted rapidly, which was a challenge for the heat dissipation system of the charging pile. In order to reduce the operation temperature of the charging pile, this paper proposed a fin and ultra-thin heat pipes (UTHPs) hybrid heat dissipation system for the direct-current (DC) charging pile.
EV DC charging piles mainly consisted of the power input modules, power modules, charging buses, fans, charging control units, electric energy metering units, and human-computer interaction units, etc. . The progress of the charging pile technology, particularly the charging speed, was crucial to the development of EVs .
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 peak temperature of the chip were studied with the heating power increased from 100 W to 450 W. According to the "Off-board bi-directional charger for electric vehicles general technical requirements" (Q/GDW 397-2009) formulated by Chinese government, the peak temperature of the chip should be lower than 85°C for safe and stable operation.
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.
On the other hand, the heat dissipation system inside the charging pile should also be improved. However, because the heat flux density of the new generation of EV DC charging pile could reach 100 W/cm², the increase in temperature significantly affected the reliability of the charging module .
