Liquid cooling lowers the internal temperature of equipment by circulating a liquid coolant, which requires heat-generating components to maintain good contact with the heat sink. The heat exchange process in liquid cooling systems ultimately dissipates heat to the external environment through a liquid chiller. Because the equipment contains liquid, liquid cooling systems can provide a relatively high level of protection.
How does it work?
1. The energy storage battery generates heat during operation.
2. The coolant absorbs heat from the battery through cooling plates and is circulated by a water pump.
3. The heated coolant flows through the evaporator, where it transfers heat to the refrigerant by causing the refrigerant to evaporate.
4. The refrigerant is compressed and enters the condenser, where it releases heat to the environment by exchanging heat with the air.
5. The condensed refrigerant passes through the expansion valve and returns to the evaporator, starting a new cycle.
Advantages
1.Liquid cooling facilitates more uniform and efficient heat dissipation, making it especially suitable for high-power operational scenarios.
2.A uniform temperature distribution can significantly enhance battery cycle life.
3.Liquid cooling effectively suppresses the propagation of battery thermal runaway, thereby reducing safety risks.
4.Liquid-cooled systems typically operate more quietly than air-cooled systems.
5.High heat dissipation efficiency helps reduce the footprint of energy storage systems. For example, the Greensun 125 kW/261 kWh liquid-cooled energy storage system occupies only 1.68 m², saving considerable space.
