Orthogonal experimental design of liquid-cooling structure on the cooling effect of a liquid-cooled battery thermal management system

In order to analyze the influence of four parameters on the cooling effect of a liquid-cooled battery thermal management model, a L-16(44) orthogonal array is selected to design sixteen models to perform and quantify the parametric to identify the main and secondary factors, then the optimal combination model is found. The results show that the number of the pipe has most obvious effect on the average temperature of the cooling plate in the four parameters, and velocity of coolant flow is second, pipe height has the minimal effect. In terms of temperature uniformity, amount of pipe and velocity of coolant have similar effects which are both main factors, pipe width and pipe height have similar effects which are both secondary factors. The optimal case by this orthogonal analysis can meet various cooling conditions. (C) 2017 Elsevier Ltd. All rights reserved.
