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 efficiency of heat transfer in an energy pile depends on the design parameters concerning the characteristics of the pile, pipe, concrete, fluid, and ground. The configuration of heat exchanger pipes is found to be the most influential parameter.
The thermal process goes in an energy pile, as in a borehole heat exchanger, in different stages: heat transfer through the ground, conduction through pile concrete and heat exchanger pipes, and convection in the fluid and at the interface with the inner surface of the pipes (Fig. 2).
The heat flow should also be addressed to consider the actual thermal behavior of energy piles. The thermally-induced changes of stresses and strains in energy piles depend strongly on the pile fixity and can reach critical values if the restraint conditions are not correctly defined.
