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.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
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.
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 .
