Air cooling or liquid cooling system, how to choose?

The integrated photovoltaic and storage machine is an integrated solution that integrates photovoltaic controllers and bidirectional converters to achieve "light + energy storage". Optical and storage integrated machines generally have two different heat dissipation methods: air cooling and liquid cooling.

The air cooling system uses fans to move air across the surface of the equipment to remove heat. Hot air is discharged through the vents in the device housing to cool the device. Liquid cooling systems use liquid (usually water or other coolants) to absorb the heat generated by the equipment. The liquid flows through the inside of the equipment through pipes and then dissipates the heat to the external environment through the cooling device. The air-cooling system is suitable for small and medium-power optical and storage integrated machines, and is usually used in scenarios that do not require excessive heat dissipation efficiency. Due to its simple structure, maintenance is relatively easy and the cost is relatively low. However, its heat dissipation effect is greatly affected by factors such as ambient temperature and air circulation, and it is not suitable for high-power and high-density equipment.

Liquid cooling systems are usually used in high-power, high-density, high-performance optical and storage integrated machines, and have better heat dissipation efficiency in high-temperature environments. However, the cost is relatively high and the design is more complex. The layout and pump of the liquid circulation system need to be considered. issues such as selection, coolant circulation and regular maintenance.

Air cooling systems are suitable for energy storage systems of various sizes and types, especially in outdoor environments. It is currently the most widely used cooling technology, such as used in industrial refrigeration, communication base stations, data centers, temperature control scenarios, etc. The technology maturity and reliability are relatively high. Especially in low and medium power scenarios, air cooling is still the mainstream.

The liquid cooling system battery pack has high energy density, fast charging and discharging speed, and its advantages are particularly obvious in situations where the ambient temperature changes greatly. However, liquid cooling produces higher noise and has a certain impact on the environment. Due to its small radiator size, it can effectively save space. In addition, liquid cooling can also reduce the impact of noise on the environment by optimizing the design and layout of the radiator.

Air-cooled heat dissipation is safer because of its simple structure and no risk of liquid leakage. However, you need to pay attention to the safety of the fan to prevent damage or overheating of the fan.

The safety of liquid cooling is relatively low, and there are risks such as liquid leakage and corrosion. Therefore, liquid cooling systems require high-quality materials and strict sealing designs to ensure safe operation. Therefore, domestic products generally choose to install liquid cooling systems, while most products exported to foreign countries choose air-cooling systems.
