Abstract
In order to fully utilize the advantages of active and passive heat dissipation in the battery heat dissipation system of liquid cooled composite phase change materials,a simulation model of the composite heat dissipation system was established,and the synergistic idea between different heat dissipation modules in the composite system was proposed.Based on this idea,the optimal values of the filling amount,liquid cooling start time,and coolant flow rate of the composite phase change material(CPCM)in the system were explored.The results indicated that the synergy between CPCM filling amount,liquid cooling start time,and coolant flow rate had a significant impact on whether the composite system could fully utilize the active and passive heat dissipation advantages of each module.When the battery spacing reached 2mm,the filling amount of CPCM could meet the heat dissipation requirements of the battery at low magnification.Turning on the liquid cooling module when the liquid fraction of CPCM was 0.9 could significantly improve the utilization rate of CPCM module.When the coolant flow rate was greater than 0.03m/s,the temperature rise of the battery could be suppressed.When the flow rate was greater than 0.2m/s,the latent heat of CPCM could be recovered.Choosing the corresponding speed according to the different needs of the car could achieve the goal of reducing energy consumption.This article proposed a collaborative approach that could provide a new approach for the research of composite heat dissipation systems.关键词
