detailed description

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

Referring to Figures 1 to 3, a polygonal automobile air-conditioning refrigeration device in the present invention includes a heat exchanger 2, a semiconductor refrigeration plate 3 and a cooling water tank 5, and the shell 1 of the heat exchanger 2 is of a regular hexagonal cylindrical structure Housing 1, the two ends of the housing 1 are air inlet 6 and air outlet 7 respectively, each outer surface of the housing 1 is fixed with a cooling water tank 5 with the same fixed surface shape, and the housing 1 and the cooling water tank 5 are interposed There is a semiconductor refrigerating sheet 3, and the periphery of the semiconductor refrigerating sheet 3 is separated from the casing 1 and the cooling water tank 5 by being provided with a thermal insulation gasket 4 to prevent heat transfer. Each outer surface of the casing 1 and the cooling water tank 5 are separated from the semiconductor refrigerating sheet. The 3 contact surfaces are provided with grooves 8 for accommodating and installing semiconductor cooling chips 3. The sum of the groove depth of the two grooves 8 and the thickness of the heat insulating gasket 4 is equal to the thickness of the semiconductor cooling chips 3; the semiconductor cooling water tank 5 passes through the bolt 9 Fixed on the outer side of the housing 1, the joints of the bolts 9 are padded with disc springs 10 to prevent thermal expansion and contraction.
