Three cooling methods for thermal management cooling system of BESS

💧 air cooling technology
The air cooling and heat management system has air conditioning structures including floor integrated, overhead integrated, split and other configurations. A floor integrated air conditioner is used in an energy storage container with reserved air conditioning space. Air is discharged from the top of the container and connected to the air channel inside the container to provide accurate air supply to battery packs.

If there is no space for air conditioners inside the storage container, use an overhead integrated air conditioner. The air conditioner is installed on the top of the container to cool batteries from the top.
The internal unit of the split air conditioner is installed in the battery pack, and the front and back air supply is connected to the air outlet of the air conditioner and the air duct to directly cool the battery.

💧 liquid cooling technology
In the liquid cooling scheme, water, ethanol, silicone oil and other coolants are used to dissipate heat through indirect contact between the conductive trough and the battery cell evenly distributed on the liquid cooling plate. Its advantages include:

1) Close to the heat source, effective cooling;
2) Compared with the container air cooling scheme of the same capacity, the liquid cooling system does not need to design air ducts, which is more suitable for large-scale energy storage power stations;
3) Compared with the air-cooled system, the failure rate is lower due to the reduction of the use of mechanical components such as fans;
4) Liquid cooling noise is low, saving system power consumption.

The core of the liquid cooling system of the thermal management cooling system is the chiller and the liquid cooling plate. The chiller includes compressor, condenser, throttle, evaporator and pump and other components, liquid cold plate is copper and aluminum and other raw materials are processed into the corresponding plate, the production process of liquid cold plate is divided into brazing, blowing, die casting, stamping, friction stir welding and so on.

💧 phase change cooling
Phase change cooling is a kind of cooling method that uses phase change material to absorb heat. The selection of phase change material has a greater impact on the heat dissipation effect of the battery. When the specific heat capacity of the selected phase change material is larger and the heat transfer coefficient is higher, the cooling effect under the same conditions is better, and the cooling effect is worse.

Phase change cooling has the advantages of compact structure, low contact thermal resistance, good cooling effect, but the phase change material itself does not have the ability to dissipate heat, the heat absorbed needs to rely on liquid cooling system, air cooling system, etc., otherwise the phase change material can not continue to absorb heat. In addition, phase change materials take up space and are costly.
