摘要
对两个热电制冷片的制冷模组进行数值模拟,分析制冷片中心间距对热耦合强度的影响;通过有限元仿真,对比分析热电制冷片中心间距和偏置距离差异对其性能的影响。结果表明:制冷片的中心间距能显著影响热耦合强度,热耦合强度随着中心间距的增大而降低;制冷片的热布局优化能使制冷模组的实际工作性能提升,在热电制冷片中心间距为100 mm,偏置中心线距离为10 mm时,模组工作性能最佳。在工作电流3 A时,相比于两片热电制冷片邻接布置,冷热面温差降低了11.66%,制冷量和制冷效率分别提升了6.76%和9.21%。
Numerical simulation of the cooling modules containing two thermoelectric coolers was carried out to analyze the influence of the center spacing on the thermal coupling strength.Through the finite element simulation,the difference between the center spacing and offset distance of the two thermoelectric coolers to impact its performance was compared and analyzed.The results show that the distance between the centers of the two coolers can significantly affect the thermal coupling strength,and the thermal coupling strength decreases with the increase of the center spacing;The optimization thermal layout of the coolers can improve the actual working performance of the cooling module.The module works best when the spacing is 100 mm and the offset centerline distance is 10 mm.When the working current is 3 A,compared with the adjacent arrangement of two thermoelectric coolers,the temperature difference between the hot and cold surfaces is reduced by 11.66%,and the cooling capacity and cooling efficiency are increased by 6.76%and 9.21%,respectively.
