摘　　要：为提高半导体制冷果蔬配送箱的工作性能,提高半导体制冷片热端散热效率,降低散热系统能耗与质量,搭建水冷半导体果蔬配送制冷箱试验平台,针对水泵流量、散热风机风速、水箱容量对半导体制冷性能的影响进行试验研究。结果表明,导体制冷果蔬配送箱最佳水冷散热参数为:水泵流量为13 cm^3/s,散热风机风速4 m/s,水箱200 m L;在该参数条件下,箱内空气温度从25℃降到7℃仅需580 s,半导体制冷片能耗25 165.20 J,制冷系统总能耗为28 408.10 J,制冷效率26.004%,保证了较快的制冷速度和较小的水箱体积,并减少降温能耗。研究结果为便携式果蔬配送系统的设计和优化提供理论依据。To increase the cooling performance of semiconductor refrigeration distribution box for fruit and vegetable, heat dissipation efficiency of semiconductor cooling chip hot end and reduce energy consumption and weight of cooling system of thermoelectric refrigerator, a test platform was designed and buik toinvestigate the influence of water pump flow, fan wind speed, water tank capacity on the cooling performance of the thermoelectric refrigerator. The results showed that,the optimal water cooling parameters of the distribution box were： water pump flow 13 cm^3/s, fan wind speed 4 m/s and tank capacity 200 mL. Under this condition, it took only 580 s to cool from 25 ℃ to 7 ℃, the energy consumption of the semiconductor refrigeration sheet was 25 165.20 J, the total energy consumption of the refrigeration system was 28 408.10 J, and therefrigeration efficiency reached 26.004%, which guaranteed higher cooling efficiency and smaller tank capacity, and less energy consumption. The research provides theoretical basis for the design and optimization of portable fruit distribution system.
