The seat body 41 has a base base wall 411 at the bottom and a horizontal, and a seat wall 412 extending upward from the periphery of the base wall 411. The base wall 411 and the seat wall 412 together define a space 40. The base wall 411 is provided with a water outlet hole (not shown) for allowing water generated in the operation of the present invention and stored in the water storage base 4 to be discharged from the water outlet hole. The seat wall 412 has an air inlet hole 413 and an air outlet hole 414 extending through the wall surface thereof. The partition 42 partitions the space 40 from an air intake space portion 401 and a water storage space portion 402. The intake space portion 401 communicates with the intake hole 413.

The heat exchanger 5 is disposed in the installation space 110 of the casing 1 and on one side of the dehumidification wheel 2. The heat exchanger 5 is for condensing the high-temperature and high-humidity air generated by the heater 3 after heating the dehumidification wheel 2 into water. The heater 3 includes a horizontal mounting wall 51 disposed on the top of the water storage base 4, a first tubular body 52 and a plurality of second tubular bodies 53 disposed on the top surface of the mounting wall 51, and a cover The first tube body 52 and the cover body 54 above the second tube body 53.

The cross-sectional area of each of the second passages 530 is smaller than the cross-sectional area of the first passages 520. Each of the second tube walls 531 of this embodiment has a thickness of about 0.2 mm to facilitate heat exchange. Wherein, since each second pipe body 53 must also be combined with the mounting wall 51 by means of welding, when the pipe diameter is too small and too thin, it will be easily melted through and will not be favorable for fusion bonding; when the thickness is too large, the pipe If the path is too thick, the welding will not be tight. Therefore, the thickness should be appropriate, too thin and too thick will cause air leakage, and the performance of the heat exchanger will be reduced.

When the embodiment is used, room temperature air enters the interior of the dehumidifier through the air inlet 114 of the casing 1. The dehumidification wheel 2 absorbs moisture in the air, so that the dehumidifier can blow dry air out through the air outlet 116. And achieve the effect of dehumidification and air dryness. On the other hand, after the dehumidification wheel 2 absorbs moisture, the heater 3 can heat the dehumidification wheel 2 to dry the dehumidification The water vapor absorbed by the wheel 2 reduces the dehumidification wheel 2 to a state of being dry and re-adsorbing moisture. The moisture adsorbed by the dehumidifying wheel 2 is heated into high-temperature and high-humidity air, and enters the heat exchanger 5 through the intake hole 413 of the water storage base 4. The high temperature and high humidity air first enters the first passage 520 of the first pipe body 52, and passes upward through the cover body 54 and then enters the second passage 530 of the second pipe body 53. When the high temperature and high humidity air enters the second passages 530, heat exchange can be performed with the room temperature air sucked by the dehumidifier (relative to the high temperature and high humidity air flowing into the second passage 530), and the high temperature is high. The moisture in the humid air is further condensed to form water droplets, and the water is dropped into the water storage space portion 402 of the water storage base 4; and the high-temperature and high-humidity air is subjected to heat exchange to become low-temperature air, and is discharged from the air outlet 414. It should be noted that when the high temperature and high humidity air is in the first passage 520, heat exchange may also occur. The function of the partition 42 can be used to separate high temperature and high humidity air from low temperature air.

For example, the first tube body 52 of the present embodiment has a cross-sectional circumference of about 138.8 mm, and the first tube body 52 has a length of about 187.5 mm. Therefore, the first tube body 52 provides a heat exchange area of about 138.8 mm. ×187.5=26025mm². In this embodiment, 86 second tubes 53 can be disposed. Each second tube 53 has a length of about 187.5 mm, and the second tube 53 has an inner diameter of about 6.6 mm. Therefore, the 86 second tubes 53 are provided. The heat exchange area is approximately 86 × (187.5 × 6.6 × Π) = 334174.5mm². Therefore, the heat exchange area of the heat exchanger 5 of the present embodiment provides a heat exchange area of up to 26,025+334174.5=360199.5 mm.² 。

In summary, the present invention provides a single first body by providing a single body 52, in cooperation with the second tubes 53, the tubular structure can provide a large heat exchange area, thereby improving heat exchange efficiency.
