Water cooling system mainly includes: water pump, heat exchanger, heat sink, expansion Water Tank, etc.

Water cooling technology is based on liquid heat exchange cooling technology, which is more efficient than air cooling technology. The internal temperature of the battery pack of electric vehicles is more uniform. It can be integrated with the vehicle's cooling system. The heat exchange coefficient with the battery wall is high, and the cooling Fast heating. However, the system using water cooling technology is more complicated, heavy, difficult to repair and maintain, and there is a possibility of liquid leakage.

Overseas studies on water-cooling technology are earlier and the application time is longer. With continuous exploration, practice and improvement, the heat exchange coefficient and cooling and heating speed of the system have reached a good level, and through the application of new materials, The weight of water cooling systems abroad has also been reduced.

At present, water cooling technology is mainly used in auto brands such as Tesla, GM Volt, French Peugeot Citroen, and BMW i3. Tesla Model S uses water cooling technology to cool the battery. Tesla has carried out in-depth design on its battery arrangement, thermal management system, and battery management system to ensure that each battery unit is under supervision and its status data can be fed back and processed at any time. For a single battery cell with a small volume, Tesla enclosed it in a steel compartment independently. At the same time, the liquid cooling system can be specific to cool each battery cell, reduce the temperature difference between each other, and relatively reduce the battery's spontaneous combustion. risk.
