Liquid cooling systems remove heat through liquid circulation, with good heat dissipation effects, but at a high cost, and are suitable for high-power, high-density energy storage systems; air cooling systems remove heat through air flow, with a low cost, but the heat dissipation effect is greatly affected by the environment, and are suitable for medium and low power energy storage systems.

The temperature difference of the hottest cell between air cooling and liquid cooling reduces with an increase in power consumption. For the power consumption of 0.5 W, the average temperature of the hottest cell with the liquid cooling system is around 3 °C lower than the air cooling system.
Is liquid cooling more efficient than air cooling?
The liquid cooling system is more efficient than the air-cooling system within the investigated range of power consumption as it is capable of keeping the temperature lower than the air cooling method. Fig. 19. Average temperature increases in the hottest cell versus power consumption.
Does the temperature difference between air cooling and liquid cooling affect power consumption?
However, the temperature of the hottest cell in the liquid-cooled module is lower than the air-cooled module within the investigated range of power consumption. The temperature difference of the hottest cell between air cooling and liquid cooling reduces with an increase in power consumption.
Which cooling system is the most energy consuming?
It was concluded that the air cooling system is the most energy-consuming method. Additionally, fin cooling is the heaviest cooling method considering the same volume for all kinds of cooling solutions.
For the power consumption of 0.5 W, the average temperature of the hottest cell with the liquid cooling system is around 3 °C lower than the air cooling system. For 13.5 °C increase in the average temperature of the hottest cell, the ratio of power consumption is around PR = 860.
What is the flow rate of liquid cooling system?
Air cooling and liquid cooling control equations In this study, the flow rate of 3 L / s to 21 L / s is considered for the air cooling, and the flow rate of 0.5 L / m i n to 3.5 L / m i n is investigated for the liquid cooling system.
