Cooperative optimization and energy conservation of IGBT liquid-cooled plate field for new energy loaders
To improve the heat transfer and power consumption of an LCP,we build a 3D model and verify its numerical simulation through our experiments.With the structural parameters(amplification factor,width of cooling column,number of cooling column,height and width of flow channel),the corresponding 16 groups of orthogonal test improvement schemes are examined.Based on the field coordination principle,Improvement Scheme 10 with better heat transfer and lower power consumption is selected by heat transfer coordination angle β and pressure coordination Angle θ,and compared with the original scheme.Finally,the numerical optimized scheme is employed to verify the improvement.Results show our numerical simulation is in line with the experimental data with a biggest error of 6.61％.The average β and θ of Improvement Scheme 10 are down by 0.97％and 1.04％respectively.In the overall y,the largest difference of the two is 0.372％.After the optimizaiton,the outlet temperature of coolant increases by 4.62～5.93 ℃,the speed rises by 0.1 m/s and the pressure loss reduces by 161.89 Pa.
