Design of Cooling System for DC Charging Station of Electric Vehicles
Design and research on the cooling system for the existing DC charging piles of electric vehicles to address the problem of heat dissipation.Firstly,the main factors affecting the heat dissipation difficulty of charging piles were analyzed.Secondly,research was conducted on the structure and ventilation design of electric vehicle DC charging piles,with a focus on the analysis process of ventilation system and ventilation volume.The conversion relationship between various indicators was given,and a three-dimensional model was established using a 150 kW DC charging pile as an example.Again,thermal simulation analysis was conducted using Ansys Icepak software to optimize the design scheme based on the analysis results.Finally,by comparing and analyzing the temperature field cloud map and particle velocity field cloud map before and after optimization,it is concluded that this scheme can effectively avoid short circuits in the heat dissipation duct and improve heat dissipation efficiency.
