Liquid Cooling Enables Better Energy Storage Temperature Control

• Lower Battery Pack Temperature:

Under the same inlet temperature, maximum airflow, and flow rate conditions, liquid cooling delivers more efficient heat dissipation. Compared with air cooling, the maximum battery pack temperature can be reduced by 3–5°C.

• Lower Operating Energy Consumption:

To achieve the same average battery temperature, the operating energy consumption of an air cooling system is approximately 3–4 times higher than that of a liquid cooling system.

• Lower Risk of Battery Thermal Runaway:

Liquid cooling systems use high-flow coolant to provide forced heat dissipation for battery packs while redistributing heat between battery modules, helping to quickly suppress the worsening of thermal runaway and reduce safety risks.

• Lower Total Investment Cost:

Liquid cooling systems maintain batteries within an optimal operating temperature range more effectively, extending battery life by over 20% compared with air cooling systems. From a full lifecycle perspective, overall investment costs are lower.

Working Principle

• Coolant Side:

The coolant absorbs heat from the battery cold plates and releases it through the evaporator. Driven by the water pump, the coolant then circulates back into the cold plates to continuously absorb heat generated by the equipment.

• Refrigerant Side:

During operation, the evaporator (plate heat exchanger) absorbs heat from the coolant circulation system through refrigerant evaporation. The refrigerant is then compressed by the compressor and enters the condenser, where heat is released into the surrounding air through condensation. Afterward, the condensed refrigerant returns to the evaporator through the expansion valve for another evaporation cycle, repeating the process continuously.

Key Components

The energy storage liquid cooling thermal management system mainly consists of a liquid cooling unit, battery cold plates, circulation pipelines, and other key components.

Liquid cooling systems eliminate the need for complex air duct design, reducing installation space by more than 50%, making them more suitable for future utility-scale energy storage power stations above 100 MW;
With fewer mechanical components such as fans, system failure rates are lower;

Liquid cooling systems operate with lower noise and lower auxiliary power consumption, making them more environmentally friendly.
