The cooling fan 36 and the radiator 33 form a sealed cooling air cavity through the cooling fan bracket 35, and the cooling air cavity and other air channels are mutually independent, so that the mutual influence is avoided, and the cooling effect is reduced.

As shown in fig. 6, the flow direction of the air flow for heat dissipation is indicated by a schematic line L2, and it can be seen from the figure that the external air enters the heat dissipation fan 36 from the heat dissipation air inlet 122, flows to the heat dissipation device 33 through the heat dissipation fan 36, and the heat dissipation device 33 is disposed at the hot end of the semiconductor cooling fin 32, so that the air absorbs the heat energy transferred from the hot end of the semiconductor cooling fin 32 to the heat dissipation device 33, and finally is output to the outside from the heat dissipation air outlet 121, thereby dissipating the heat of the hot end of the semiconductor cooling fin 32. According to the working principle of the semiconductor cooling fin 32, when the temperature difference between the cold end and the hot end is smaller, the cold end refrigerating efficiency is higher, so that the working efficiency of the semiconductor cooling fin 32 can be improved by cooling the hot end of the semiconductor cooling fin through the cooling mechanism, and correspondingly, the cold end refrigerating efficiency is also higher.

Wherein the fan bracket 52 forms a closed air flow channel between the air supply fan 51 and the second refrigeration assembly 3, so that air is conveyed in a closed loop inside the first refrigeration assembly 2 and the second refrigeration assembly 3.

Since the air inlet 114 and the air outlet 115 are disposed adjacently, the refrigerating efficiency can be further improved. On the one hand, the air inlet 114 is disposed adjacent to the air outlet 115, the temperature of the air sucked from the air inlet 114 is lower than that of the air in the environment, and the air entering from the air inlet 114 flows through the cold transfer portion 211 of the first refrigeration component 2, the cold transfer portion 211 is used for transferring the cold energy of the phase change material stored in the cold storage member 21, according to the heat transfer principle, the smaller the temperature difference is, the slower the energy transfer speed is, the larger the temperature difference is, the faster the energy transfer speed is, when the air with lower temperature near the air outlet 115 is sucked into the cold transfer portion 211, compared with the air with lower temperature in the sucked environment, the smaller the temperature difference is between the air and the cold transfer portion 211, the lower the cold energy released from the phase change material is, the same time for releasing the cold energy of the phase change material is longer, and the loss is smaller for the neck air conditioner, and the refrigeration efficiency is higher.

On the other hand, when the gas cooled by the cooling portion 211 flows through the cooling guide 31 again, the temperature of the gas flowing through the cooling guide 31 is lower because the gas is cooled once, and the cooling guide 31 is used for transferring cold end cold energy of the semiconductor cooling plate 32, so that the cold end cold energy of the semiconductor cooling plate 32 is consumed less, and the cooling efficiency of the second cooling assembly 3 is further improved.
