摘要：
A thermal-and-energy-conservation optimization was numerically investigated in this work for a liquid-cooled plate (LCP). Firstly, a three-dimensional model was established, and its numerical analysis was verified with experimental data. Then, the common correlations of heat transfer synergy β and pressure synergy θ involving the amplification factor, the width of cooling columns, the number of cooling columns, the height and the width of flow passage were derived from the traditional j and f correlations, which were later solved by the least-square method and tested with regression and F significance test. With those correlations, a multi-objective optimization was performed, and its outcomes were assessed by a comprehensive evaluation index g for thermal performance and auxiliary entropy generation for energy conservation. At last, Optimized Scheme 2 (OS2) was numerically compared with the original one to confirm improvements. It is found that, over the whole speed range, the maximum error between both results is 6.61%. The test shows that the fitting correlation may predict 94.79% of β with -0.039% mean error and 98.96% of θ with 0.099% mean error. Among outcomes, OS2 contributes a better g, 50.6393°, for thermal performance and a smaller entropy generation, 0.09175 W/K, for energy conservation. Furthermore, the comparison also supports that finding with the decreased β of 0.39%, the decreased q of 3.33%, the increased g of 0.34%, and the increased entropy generation of 3.99% in OS2. © 2023, The Authors.
