Customer ServiceTemperature distribution of the contact surface between the battery and the cooling plate. Fig. 11 (a) (b) illustrate the temperature variation of the coolant flow direction (X-axis) at the end of discharge. It can be observed that the temperature rise of the coolant increases at the groove end.
Since the VHTP cooling plate was optimized for a coolant flow rate of 0.005 kg/s, the grooves of the VHTP cooling plate may become a limiting factor for battery heat dissipation at higher flow rates. Therefore, the cooling performance of the optimized VHTP cooling plate at a higher flow rate (0.01 kg/s) was also analyzed. Fig. 15.
To better explore the thermal management system of thermally conductive silica gel plate (CSGP) batteries, this study first summarizes the development status of thermal management systems of new energy vehicle power batteries to lay a foundation for subsequent research.
By designing grooves of different geometric sizes on both sides of the coolant channel, the heat transfer path between the battery and the coolant is changed, and the temperature of the battery surface at the inlet of the coolant is increased to improve the temperature uniformity of the battery. Fig. 1.
1)The grooves on the VHTP layer change the heat transfer path between the coolant and the local battery surface, resulting in heat accumulation on the groove surfaces and heating of the surrounding areas. Overly large groove sizes lead to an increase in the maximum temperature of the battery.
