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.
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.
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.
The heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system. At present, the typical high-power direct current EV charging pile available in the market is about 150 kW with a heat generation power from 60 W to 120 W ( Ye et al., 2021 ).
Electric vehicle charging piles employ several common heat dissipation methods to effectively manage the heat generated during the charging process. These methods include: 1. Air Cooling: Air cooling is one of the simplest and most commonly used methods for heat dissipation in EV charging piles.
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.
