The main factors affecting the heat transfer performance of spray cooling are discussed. Through the experiments, the influence of spray cooling on the thermal management of the battery thermal management system under high discharge rate is studied. The results show that, in spray-cooling 4 + 2.5 m/s cooling mode, the total heat transfer coefficient K reaches 201.0 W/(m2 K), which is 409.3% higher than the heat transfer coefficient of the forced air cooling. In addition, the difference between the spray concentration of the heat source surface and the spray concentration of the mainstream area during steady-state heat dissipation is an important factor affecting the heat transfer performance of spray cooling. Moreover, spray cooling can provide a lower temperature rise and a more uniform temperature distribution for the battery module. For the spray-cooling 4 + 4 m/s case, the maximum temperature rise is only 10.3°C, and the temperature difference among the battery module is stably maintained within 5°C. Therefore, the proposed spray cooling battery thermal management system shows to be efficient approach in handling the heat accumulation of battery module.
