摘　　要：如果能够对速冻产品解冻时产生的低温冷能进行回收利用,可以减少不必要的能源浪费,但是目前基于温差发电技术的冷能回收研究较少,为此开发了一冷能回收模拟试验台并进行了相关研究。研究结果表明,基于解冻水的温差发电是可行的;由于温差发电片高度较小在热辐射作用下使得冷端和热端温度会逐渐趋近,采用提升温差发电片高度、增大散热片面积的方式都可以减少这种趋势,增大温差发电片两次温差;环境风同样能够改善温差发电片两侧的温差,但是改善程度存在极限值。If the cold energy of frozen products can be recovered,it can reduce unnecessary energy waste.However,there are few researches on cold energy recovery of thawed water based on thermoelectric generation(TEG)technology.Therefore,a simulation test bed of cold energy recovery was developed and related researches were carried out.The results show that the energy recovery can be realized using thawed water based on thermoelectric generation.And the temperature of both ends will gradually approach under the action of thermal radiation due to the small height of the thermoelectric generator modules.By raising the height of the thermoelectric generator and increasing the area of the heat sink,this trend can be reduced and the temperature differences between the hot and cold end of the thermoelectric generator can be increased.Moreover,the ambient wind can also improve the temperature difference of both ends of the thermoelectric generator modules,but there is a limit.
