Because the TEC24 works in a large temperature difference environment and the thermal conductivity coefficient of the sealing silica gel is relatively high, the refrigeration loss is easily caused, in order to reduce the heat loss of the sealant in transmission, a vinyl acetate Copolymer (EVA for short) and silica gel sealing technology can be further adopted, the thermal conductivity coefficient of the EVA material is far smaller than that of the sealing silica gel, and the refrigeration loss of the TEC24 caused by the sealing silica gel can be effectively reduced. In addition, low-heat-conduction sealing materials (such as high-density sponge) can be adopted for sealing around the TEC24, so that the TEC24 works in a closed environment to realize isolation from the surrounding air environment, thereby not only preventing moisture from entering the TEC24 to cause the reduction of the refrigeration performance of the TEC24, but also reducing the refrigeration loss caused by sealing glue. In order to ensure more cold generation, a plurality of TEC24 can be connected in parallel or in series.
