The invention discloses a vehicle-mounted refrigerator assembly which comprises two or more semiconductor refrigeration devices, cold and hot surfaces of the semiconductor refrigeration devices are overlapped to generate a larger temperature difference between heat dissipation surfaces inside and outside the refrigerator, and during refrigeration, the inner side end of a cavity of a refrigerator body where the semiconductor refrigeration devices are located is a cold end, and the outer side end of the cavity of the refrigerator body is a hot end; during heating, the inner side end of a cavity, where the semiconductor refrigerating device is located, of the refrigerator body is a hot end, and the outer side end is a cold end. The positive electrode and the negative electrode of the semiconductor refrigeration device are connected through a positive electrode and negative electrode switching circuit, and switching of the refrigeration function or the heating function is achieved and completed through positive electrode and negative electrode switching. The vehicle-mounted refrigerator assembly capable of switching cooling and heating is achieved in the mode that two or more layers of refrigerating devices are stacked, and compared with a traditional refrigerant compressor refrigerator, the vehicle-mounted refrigerator assembly has the advantages that cost and noise are reduced, cooling and heating switching and rich interaction of RGB full-color lamps can be achieved, and the like.
本发明公开了一种车载用冰箱总成,包括半导体制冷器件两片或以上冷热面叠加,产生箱内和箱外散热面之间的更大的温度差,制冷时:位于所述半导体制冷器件所在的冰箱箱体腔体内侧端为冷端,外侧端为热端;制热时,位于半导体制冷器件所在的冰箱箱体腔体内侧端为热端,外侧端为冷端;半导体制冷器件的正负极采用正负极切换电路相连,通过正负极切换实现并完成制冷或制热功能的转换。本发明通过两层或以上制冷器件堆叠的方式实现了可切换冷暖的车载冰箱总成,与传统冷媒压缩机冰箱对比,即降低了成本和噪音,又能实现冷暖切换和RGB全彩灯丰富交互等优点。
