Design of battery pack liquid cooling structure and analysis of influencing factors
摘要
Abstract
The structure of liquid cooling plate has a significant impact on batteries' heat dissipation effect and homogenization.When comparing the heat dissipation performance of different structures,the liquid mass flow of various cold plate structures is constrained for simulation study. First,different heat dissipation structure schemes are designed and the heat dissipation simulation is conducted under the same mass flow condition to compare the heat dissipation effect and pump power consumption of each design scheme.On this basis,the influence of the water inlet diameter,wall thickness and water temperature on the heat dissipation effect is discussed.Our results show the heat dissipation effect of transverse parallel cold plate structure is the best with inner diameter,wall thickness and water temperature standing at 36 mm,2 mm and 25 ℃ respectively.Our ultimate heat dissipation scheme meets the temperature control requirements of the optimal operating temperature range of the battery pack of 20~50℃ and the maximum temperature difference of 5 ℃.关键词
