Temperature 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.
It has been widely adopted in EVs by automotive companies . The cooling plate is an important guarantee for the performance of liquid-cooling thermal management systems. Huo investigated the influence of microchannel number, flow direction, and inlet flow rate on the heat transfer performance.
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.
It can be observed that the temperature rise of the coolant increases at the groove end. This indicates that the coolant at the groove end has a cooling effect on the battery surface in the groove area, and effect the battery surface temperature at the coolant inlet (Fig. 10).
The proposed design does not conflict with the design of the cooling channel. The optimal design of the VHTP cooling plate should consider the maximum coolant flow rate. Liquid-cooled battery thermal management system (BTMS) is of great significance to improve the safety and efficiency of electric vehicles.
