Abstract：By using the 3D control equations of incompressible fluid flow,a mathematical model of a new energy automotive battery cooling plate heat transfer was established.Using this model, selection of glycol water solution as cooling medium,at initial temperature of 15 ℃,with the boundary condition of the quality of imported flow heat of 0.179 kg/s transfer analysis was made.The heat transfer effect is good, but there were problems of low heat transfer efficiency and large cooling plate quality.The original scheme of internal grid structure was changed to plate fin structure and internal structure was analyzed and optimized by orthogonal test.The cooling plate weight was reduced by 13.9% after optimization.Because the heat transfer area increases, heat power increased by 11.36% to achieve the purpose of optimization design.
