摘　　要：提出了在露天环境下一种太阳能半导体保鲜装置,并对装置结构、半导体制冷组件、光伏组件进行了设计计算与选择,最后对该装置进行实验研究与分析。实验表明,在稳定工况下半导体制冷片存在最佳制冷系数的电流Iopt=2.7 A,最大制冷量的电流Io=3.5 A;不同环境温度下保温箱的温度在40-50 min时趋于稳定,且在环境温度T0=30℃时,半导体制冷系数COP达到最大值为0.426;随散热风扇电压增大,半导体制冷系数COP增大,而系统COP’先增大后减小,且在环境温度T0=30℃、输入电压为10 V时COP’达到最大值为0.391。A solar semiconductor preservation device in open air environment is proposed. The device structure, semiconductor module and photovoltaic module are designed, calculated and selected. Finally, the device is experimentally studied and analyzed. The experiment shows that the semiconductor refrigeration sheet exhibits the optimal refrigeration coefficient with the current Iopt= 2.7 A and the maximum refrigeration capacity with the current Io=3.5 A under stable conditions. The temperature of the incubator tends to be stable at 40-50 minutes under different ambient temperatures, and the maximum of the semiconductor refrigeration coefficient cop is 0.426 at ambient temperature T0=30 ℃. With the increase of the fan voltage, the semiconductor refrigeration coefficient COP increases, while the system COP′ increases first and then decreases, and the maximum value of COP′ is 0.391 when the input voltage is 10 V and the ambient temperature is 30 ℃.
