In the design of a project, the first step must be to clarify the customer's needs. In addition to general needs, you should also put yourself in the shoes of the surrounding needs. Even if the customer does not mention it, we'd better consider it privately in advance. For liquid cooling systems, the basic requirements.

Direct liquid cooling involves circulation of a coolant between battery cells to cool them directly (Larrañaga-Ezeiza et al., 2022). By contrast, in indirect liquid cooling, cooling plates installed beneath the battery cells are utilized to create a network of cooling channels that dissipates heat indirectly (Deng et al., 2018).

For three types of liquid cooling systems with different structures, the battery’s heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
Orthogonal analysis was conducted to investigate the influence of each variable on the cooling performance of the battery module. It was confirmed that increasing the number of channels was the most effective method for improving the cooling performance and reducing the pumping power.

This is due to the fact that the pressure drop was minimized by widening the cooling path, while maintaining the same flow rate. As the channel width of the cooling plate increased, the average temperature of the battery module decreased; however, the temperature difference between the upper and lower parts of the module increased.
