Performance Analysis And Structural Optimization Of S-shaped Flow Channel Liquid-cooling Plate

This paper mainly studies fluid-solid coupled heat transfer simulation technologyof S-shaped flow channel liquid cooling cold plate. According to the requirements ofcooling chips, two different structure flow channels of liquid cooling cold plate aredesigned and the theory and simulation of them are researched. In order to improvethermal performance of the cold plate, iSIGHT-FD optimization software is used tooptimize design parameters of liquid-cooled cold plate. Main tasks are as follows:Firstly, structure design and theoretical analysis of cold plate is conductedaccording to cooling requirements of IGBT module on the basis of thermal designtheory. Thermal performances of two different liquid-cooled cold plates are calculatedpreliminary.Secondly, researching the methods of integrating Pro/E, ICEM-CFD, CFX-Pre,CFX-Solver and CFX-Post into iSIGHT-FD,the liquid-cooled cold plate integratedsimulation platform is established. The cooling performance of the second cold plate issimulated and compared with the theoretical analysis. This test validates the reliabilityof simulation software and analyses the influence of major parameters on the thermalperformance of cold plate.Finally, the key technology of Latin hypercube experimental design method tosolve cold plate multi-objective optimization, is researched. The design parameters ofliquid-cooling plate are simulated and optimized according to the selected optimizationmethod, and the optimization design process is analyzed in detail. The article obtains24group optional parameter group and the best runner structure by integrated simulationoptimization platform of iSIGHT-FD, and provides guidance for the structural design ofthe cold plate.
