The fin condensers 3, the fin radiator 4 and the fan 5 are arranged in sequence from front to back, and a semiconductor refrigerator 6 is sandwiched between each fin condenser 3 and the fin radiator 4. The cold end of the semiconductor refrigerator 6 is attached to the fin condenser 3, and the hot end of the semiconductor refrigerator 6 is attached to the fin radiator 4. The fins 30 of the fin condenser 3 extend in the vertical direction, and the fins 30 of the upper and lower rows of the fin condensers 3 are aligned with each other. A water inlet 20 is provided at the top of the water tank 2, and the water inlet 20 is located below the fins 30.

[0026] In the above structure, the water tank 2 is detachably mounted in a position near the bottom of the housing 1. A plurality of fin condensers 3, fin radiators 4 and fans 5 are arranged above the water tank 2. A semiconductor refrigerator 6 is sandwiched between each fin condenser 3 and the fin radiator 4. When the semiconductor refrigerator 6 is working, its cold end cools the fin condenser 3. When moisture contacts the fins 30, it condenses into water, and then drips into the water tank 2 from the water inlet 20. At the same time, the semiconductor refrigerator 6 is cooled by the fin radiator 4 and the fan 5. The hot end of the device 6 is used to dissipate heat to ensure that the semiconductor refrigerator 6 works efficiently. The utility model utilizes multiple fin condensers 3 in conjunction with multiple semiconductor refrigerators 6 for condensation and dehumidification. The semiconductor refrigerator 6 can significantly reduce the temperature of the fin condenser 3. At the same time, the multiple fin condensers 3 are distributed in an array, which can greatly improve the moisture condensation efficiency and thus achieve efficient dehumidification. At the same time, the core components composed of the fin condenser 3, the fin heat sink 4 and the fan 5 are small in size, which can enable the dehumidifier to meet small-size application requirements.

The second avoidance opening 71 is used to discharge the hot air generated by the fin heat sink 4. In practical applications, the heat sink of the fin heat sink 4 extends horizontally so that the gap between the two heat sinks is aligned with the second avoidance opening 71.

[0031] In order to better cooperate with the fan 5 , in the present embodiment, a third avoidance opening 80 is opened on the second inner shell 8 , and the third avoidance opening 80 is aligned with the fan 5 .

[0032] See also Figure 2 In this embodiment, the PCB board 12 is disposed above the first inner shell 7 and the second inner shell 8. In this embodiment, the PCB board 12 is preferably disposed near the top of the housing 1 to prevent the PCB board 12 from contacting with humid air.

[0033] In order to achieve the requirement of efficient dehumidification, in this embodiment, the number of the fin condensers 3 is four, and the four fin condensers 3 are arranged in two rows.

Among them, the multiple fin condensers 3 are arranged in a square in a 2×2 array, and the four fin condensers 3 can fully contact the moisture to ensure efficient dehumidification.

[0034] Specifically, the fin 30 is a parallelogram fin with a front end tilted downward, wherein the fin with a front end tilted downward can drain the condensed water downward so that the condensed water can drip into the water receiving port 20 better.

[0035] In this embodiment, both the left and right sides of the housing 1 can discharge hot air. Figure 2 Side shells 9 are fixed to the left and right sides of the housing 1 , respectively.
