[0019] The refrigeration mechanism 3 includes a heat preservation shell 301, a heat dissipation component 302, a heat insulation plate 303, a plurality of semiconductor cooling sheets 304, a heat dissipation fin 2 305, a plurality of heat dissipation fans 2 306 and a ventilation slot 307. The outer periphery of the plurality of semiconductor cooling sheets 304 is installed inside the heat insulation plate 303, the outer periphery of the heat insulation plate 303 is installed in the middle of the heat preservation shell 301, the left side of the heat dissipation component 302 is installed on the right side of the heat insulation plate 303, the right side of the heat dissipation fin 2 305 is installed on the left side of the heat insulation plate 303, the right side of the heat dissipation fin 2 305 is installed on the left side of the semiconductor cooling sheet 304 through thermal grease, and a plurality of heat dissipation fans 2 306 are installed on the left side of the heat dissipation fin 2 305 The ventilation slots 307 are provided on the left and right sides of the heat preservation shell 301, and the left periphery of the heat preservation shell 301 is installed on the right side of the box body 1. The heat dissipation component 302 is used to dissipate the heat for the hot end of the semiconductor refrigeration plate 304, thereby improving the refrigeration efficiency of the cold end of the semiconductor refrigeration plate 304, and then the cold end of the semiconductor refrigeration plate 304 reduces the temperature of the second heat dissipation fin 305, so that the air temperature near the second heat dissipation fin 305 becomes lower, and then the lowered temperature air is blown into the interior of the box body 1 through the second heat dissipation fan 306, thereby reducing the temperature inside the box body 1 and preventing the temperature of the material inside the box body 1 from rising, so that the turnover box can maintain a low temperature state for a long time.
[0020] The outer dimensions of the card strip 5 are the same as the inner dimensions of the upper part of the box body 1. A card slot 6 is arranged on the upper part of the cover plate 2, and the outer periphery of the card strip 5 is arranged inside the card slot 6. When the cover plate 2 is covered on the upper part of the box body 1, the card strip 5 can be stuck in the card slot 6, so that two turnover boxes can be stacked together. When there is no cover plate 2, the card strip 5 can be stuck in the upper part of the box body 1 to stack the two turnover boxes together.

The plurality of heat dissipation fans 3022 are installed on the right side of the heat dissipation fin 3021, and the left side of the heat dissipation fin 3021 is installed on the right side of the insulation board 303. The left side of the heat dissipation fin 3021 is in contact with the semiconductor refrigeration sheet 304 through thermal grease. The temperature of the hot end of the semiconductor refrigeration sheet 304 is transferred to the heat dissipation fin 3021, and then the heat dissipation fan 3022 drives the flow of air near the heat dissipation fin 3021, thereby increasing the heat dissipation speed of the heat dissipation fin 3021, and then quickly dissipating the hot end of the semiconductor refrigeration sheet 304, thereby improving the cooling efficiency of the cold end of the semiconductor refrigeration sheet 304.
