摘　　要：设计了一种新型热电热泵冷风机,建立了基于热阻网络法和换热器理论的热电热泵冷风机的数学模型,推导得出了能够有效表征该热电风机制冷性能的多参数耦合方程,并利用该模型分析了制冷片工作电流、散热热阻和新风流量的影响。然后以最大效率和最大制冷量、最小制冷片冷热端温差为综合最优为目标,对以上影响因素提出了最优控制方案,并进一步讨论了热电热泵风机的性能优化方法。该多参数耦合分析方法,对于热电冷风机的研究具有很好的参考价值。This paper presented a novel thermoelectric heat hump air cooler and established a mathematic module for this system based on the method of thermal network and heat exchanger theory. It also investigated a multi - parameter coupling equation to estimate the performance of thermoelectric air cooler. The variable covering with thermoelectric working current hot - side thermal resistance and fresh air flow rate were analyzed under previous module. Finally, with the synthetically optimal objective of maximum coefficient, cooling load and minimum thermoelectric temperature difference, the performance optimization was studied and analyzed. The method of multi - parameter coupling equation could be as a greater reference for future work.
