ZLJ Direct Cooling Heating Systems
Features of Direct Cooling Heating Systems
The automotive direct cooling and direct heating system is mainly used in the battery field, which can directly cool the battery cell, module and battery pack through the refrigerant liquid during the charge and discharge test. Compared with the current natural cooling or air cooling and liquid cooling, the direct cooling system does not require secondary heat exchange and is the best cooling method. The heat exchange efficiency is high, the temperature range is wide and the equipment structure is simple, and it is very convenient to use.
