Thermoelectric cooling has a high quality of temperature control compared to Vapor Compression Cooling. This paper presents a numerical and experimental study on the effect of the cold-side heat sink design and the operating condition of its fan on the performance of thermoelectric compartment of a hybrid demotic-refrigerator. The hybrid refrigerator had three compartments. One of them was cooled by thermoelectric cooling system. A 3-D lumped model was used to simulate the cold-side fan. In the experimental part, temperature at ten points inside the TE compartment was measured. The numerical results of temperature field and coefficient of performance of thermoelectric refrigerator were in good agreement with the measured values. Performance of the thermoelectric refrigerator was investigated using the numerical simulation in the states of: (i) varying the cold-side fan rotational speed, (ii) creating vertical slots through the cold-side heat sink. Width and number of slots were varied. Results showed that running the fan at a speed, 2000 rpm, was associated with 20% increase of COP relative to running it at 500 rpm. Using plate fin heat sink resulted in bad air distribution in the compartment. Generating vertical slots in the heat sink improved the temperature uniformity inside the TE compartment.

与蒸汽压缩冷却相比，热电冷却具有高质量的温度控制。本文对冷侧散热器设计及其风扇的运行条件对混合式普通冰箱热电室性能的影响进行了数值和实验研究。混合冰箱有三个隔间。其中一个由热电冷却系统冷却。使用 3-D 集总模型来模拟冷侧风扇。在实验部分，测量了 TE 室内十个点的温度。热电致冷器的温度场和性能系数数值结果与实测值吻合较好。在以下状态下使用数值模拟研究了热电制冷机的性能：(i)改变冷侧风扇转速，(ii)通过冷侧散热器创建垂直槽。槽的宽度和数量是变化的。结果表明，相对于以 500 rpm 的速度运行风扇，以 2000 rpm 的速度运行风扇与 20% 的 COP 增加相关。使用板翅式散热器会导致隔间内空气分布不良。在散热器中产生垂直槽改善了 TE 室内的温度均匀性。
