As shown in Figure 1, its heat source comes from the thermal surface of the semiconductor refrigeration chip 6, the semiconductor refrigeration chip 6 is connected with the transformer rectifier 12, the thermal surface of the semiconductor refrigeration chip 6 is close to the thermal surface cooling plate 7, and the thermal surface cooling plate 7 A plurality of fins 8 are distributed on the top, and behind the heat dissipation fins 8 are fans 9; Extending to the top of the cold storage water tank 2, there is an agitator 14 in the cold storage water tank 2.

When the transformer rectifier 12 outputs current, the semiconductor cooling chip 6 starts to work, and generates temperatures of about 200° C. and −5° C. on its hot surface and cold surface respectively. The heat generated by the hot surface is transferred to the cooling fins 8 through the heat conduction plate 7 on the hot surface. The wind blown by the fan 9 is heated when passing through the cooling fins 8, and the heat is sent to the working area in combination with radiation heat transfer.
