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.
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. The L-shaped ultra-thin flattened heat pipe with ultra-high thermal conductivity was adopted to reduce the spreading thermal resistance.
Ming et al. (2022) illustrates the thermal management performance of the charging pile using the fin and ultra-thin heat pipes, and the hybrid heat dissipation system effectively increases the temperature uniformity of the charging module.
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 transient thermal analysis model is firstly given to evaluate the novel thermal management system for the high power fast charging pile. Results show that adding the PCM into the thermal management system limits its thermal management performance in larger air convective coefficient and higher ambient temperature.
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 .
