In this work, different types of geometrical heat cooling channel are designed for numerical analysis on liquid cooling system for lithium-ion battery module. There are three types of geometrical heat cooling channel which are cylindrical, triangular and square shape. The cross-sectional area for all the geometrical heat cooling channel is the same so that the comparison of the performance can be made. There are two battery modules that are chosen which are aluminum block and stainless-steel block in order to investigate the block thermal performance between the two battery modules. The battery module is made to fit 10 lithium-ion batteries of the same size. The cooling system depends on the geometrical heat cooling channel and the effectiveness of aluminum and stainless steel and the result will determine which geometrical and block that can provide the best thermal management. Water is used as the substance that flows inside the flow channels. The contact surface for the battery module is the same for both block and same goes to velocity that flows in heat cooling channel in order to achieve the best cooling performance. From the results, the circular shape geometric flow channels provide the best heat distribution for the thermal performance because of the equally rounded shape which make it easy for the heat to reach the center of the flow channel for heat transfer to occur evenly. And aluminum has better thermal conductivity for the thermal management.
