The battery thermostatic management water-cooling unit obtains low-temperature antifreeze by evaporative cooling of refrigerant. The low-temperature antifreeze takes away the heat generated by the battery through convection heat exchange under the action of the water pump. The liquid heat transfer coefficient is high, the heat capacity is large, and the cooling speed is fast, which is better for reducing the maximum temperature and maintaining the temperature consistency of the battery pack.
Similarly, when the weather is cold, it can utilize the high-temperature antifreeze heater, and convection exchange heats the battery pack to maintain the optimal performance of the battery pack.
