Performance Analysis And Structural Optimization Of Dense-narrow Rectangular Channel Liquid-cooling Plate

Now, liquid-cooling plate has been widely used in thermal control technology of the electronic equipment. Based on the Multidisciplinary design optimization platform iSIGHT-FD, performance simulation and structural optimization of dense-narrow rectangular channel liquid-cooling plate is studied, to complete the rapid development and optimization design of liquid-cooling plate. Main tasks are as follows:Firstly, this platform integrates the following software: the three-dimensional modeling software Pro/E, pre-processing software ICEM-CFD, fluid software ANSYS-CFX, to achieve the automatic simulation of liquid-cooling plate. The results show that, iSIGHT-FD has the following advantages: parameters lossless transmission in collaborative design, data extraction in post-processing and the subject parallel computing. So it is very suitable for the design and optimization of liquid-cooling plate.Secondly, based on the platform of iSIGHT-FD, we have completed the performance analysis of liquid-cooling plate. The main structural parameters, which make a full impact on heat transfer performance and flow resistance of cooling plate, can be obtained. And then the graph, which describes the structure parameter against heat transfer coefficient and pressure drop of import and export, can be studied and mapped.Finally, based on the platform of iSIGHT-FD, we have completed the structural optimization of liquid-cooling plate, introduced the approximate model based on response surface method, and then combined the multi-objective genetic algorithm NSGA-II with the optimized design. In the end, we have achieved the best heat transfer performance under the condition of minimum pump power for engineering application.
