The present study aims to investigate the performance of a one-stage thermoelectric cooler using mathematical and thermodynamic modeling and proposing a new correlation for performance evaluation of a thermoelectric cooler combined with two heatsinks. Validating the results of the proposed correlation, a series of experiments have been carried out on the same system. The system consists of a thermoelectric cooler and a heatsink on each side. Deriving the governing equations of the system, the effects of changing the voltage and the thermal resistance of the cold- and hot-side heatsink on cooling power, the cold-side temperature of thermoelectric, and the coefficient of performance of the system have been investigated. The results indicated that changes in voltage have a considerable effect on the performance of the system. Moreover, the maximum cooling power of the system takes place at the voltage of 14 V, which is the optimum voltage of the system. Furthermore, decreasing the thermal resistance of the hot-side heatsink leads to increasing the cooling power and the cold-side temperature of the thermoelectric cooler. On the other hand, increasing the thermal resistance of the cold-side heatsink leads to decreasing the cooling power of the system.

结合两个散热器的热电冷却器性能评估和热力学建模的实验研究。
本研究旨在利用数学模型和热力学模型研究一级热电冷却器的性能，并提出一种新的相关性，以评估结合两个散热器的热电冷却器的性能。为验证所提出的相关性的结果，已在同一系统上进行了一系列实验。该系统的两侧各有一个热电冷却器和一个散热器。推导了系统的控制方程，研究了改变冷侧和热侧散热器的电压和热阻对冷却功率，热电的冷侧温度以及系统性能系数的影响。 。结果表明，电压的变化对系统的性能有相当大的影响。而且，系统的最大冷却功率发生在14 V的电压上，这是系统的最佳电压。此外，减小热侧散热器的热阻导致增加热电冷却器的冷却功率和冷侧温度。另一方面，增加冷侧散热器的热阻会导致系统的冷却能力降低。
