摘要
For addressing the issue about cooling a prismatic LiMn2O4 battery, two mini U-channel cold plates are used to clinging to the front and back surface of the prismatic battery, respectively. The maximum temperature and temperature distribution of the battery under different flow directions (Cooling plan A and cooling plan B) are numerically investigated and analyzed. It is found that the maximum temperature of battery is reduced to about 311.8 K under the two cooling plans at the inlet velocity of 0.01 m s(-1) and the discharge rate of 1 C, making the battery in a suitable temperature range. Furthermore, the maximum temperature of battery under cooling plan A (Same flow direction) and B (Opposite flow direction) are basically the same, while the temperature distribution of battery under the cooling plan B is more uniform than that under the cooling plan A. Results suggest that the cooling plan B is more applicable for cooling a prismatic LiMn2O4 battery.
