Thermal Managment

Plate Type Liquid Cooling

Liquid cooling plate technology is a method of thermal management used in various applications, including Energy Storage Systems. This technology involves the use of specially designed plates that contain channels through which a liquid coolant flow. The plates are typically made from materials with high thermal conductivity, such as aluminium or copper. The primary purpose of liquid cooling plate technology is to efficiently dissipate heat generated by the battery cells inside the battery pack.

Working Principle:

The working principle of liquid cooling plate technology is based on the efficient transfer of heat from the battery cell to the cooling plate and then to the liquid coolant. The coolant absorbs the heat and carries it away from the source, maintaining optimal operating temperatures for the device or system. The coolant then flows through a heat exchanger, releasing the absorbed heat into the ambient environment. The cooled liquid then returns to the cooling plate to continue the process.

Advantages:

High Cooling Efficiency: Liquid cooling plate technology provides efficient heat transfer due to the high thermal conductivity of the materials used and the ability of liquid coolants to absorb large amounts of heat.
Compact Design: The design of liquid cooling plates allows for a compact and lightweight solution compared to traditional air-cooling methods.
Uniform Temperature Distribution: Liquid cooling plates can provide more uniform temperature distribution across a surface, reducing the risk of hotspots and thermal stresses on components.
Noise Reduction: Since liquid cooling systems do not require fans for heat dissipation, they can operate with reduced noise levels compared to air-cooled systems.

Immersion liquid cooling

Immersion cooling is a highly efficient method of cooling LFP battery cells It involves submerging the prismatic battery cells, in a non-conductive liquid coolant that absorbs and dissipates heat generated by the cells. The heated liquid is circulated through an external heat exchanger, where it releases the absorbed heat before being recirculated back into the system. This type of cooling is highly effective for maintaining stable temperatures across components and is ideal for applications where consistent performance is crucial. This process also allows for more efficient and effective cooling compared to traditional air-cooling methods, as the liquid coolant has a higher thermal conductivity and heat capacity than air. It also provides

Some key advantages over air cooling are:

Higher energy efficiency: Liquid coolants can absorb and dissipate heat more effectively than air, reducing energy consumption and lowering operating costs.

Immersion cooling allows for more compact system designs, as battery cells can be placed closer together without the need for large air gaps or bulky heatsinks.

Improved reliability and lifespan: By maintaining consistent temperatures and reducing the thermal stress on the battery cells, immersion cooling can extend the life of the battery cells and reduce the risk of failure due to overheating.

Noise reduction: Immersion cooling systems operate more quietly than air-cooled systems, as there are no fans or other moving parts required to circulate air.
