At least one liquid drain 115 is located at the bottom of the frame 11. The air inlet 113 is connected to the airflow duct outlet 72 and the air outlet 114 is connected to the airflow duct inlet 71. Furthermore, in this embodiment, the air inlet 113 is close to the upper end of the frame 11, and the air outlet 114 is near the lower end of the frame 11, but the air inlet 113 and the air outlet 114, Are not used to limit the present invention. Furthermore, the air inlet 113, the air outlet 114, and the liquid outlet 115 are all formed in the frame body 111. In addition, the frame body 111 further includes a separator 1113 and an opening 1114. [ The separator 1113 is positioned between the air inlet 113 and the air outlet 114 to separate them from each other.

Two covers 112 are assembled to the upper and lower ends of the frame body 111 to form an inlet flow path 1111 and an exhaust flow path 1112 together with the frame body 111. [ The inlet flow passage 1111 is between the opening 1114 and the air inlet 113. The exhaust flow path 1112 is between the opening 1114 and the air exhaust port 114.

As shown in FIG. 4, each of the heat exchange plate tubes 12 includes a main body 121 and a plurality of spacing walls 122. The shape of the main body 121 is substantially a hollow tube. The main body 121 has a first end portion 1211 and a second end portion 1212 which are mutually opposed to each other. A plurality of spacing walls 122 are assembled to the main body 121 at equal intervals and each of the plurality of spacing walls 122 extends from a first end 1211 to a second end 1212, A plurality of second flow paths 123 are formed in conformity with the first flow paths 212. The second flow path 123 is formed for the second air flow B passing therethrough. Moreover, the second flow path 123 is substantially perpendicular to the first flow path 128, but is not limited thereto. Since the outer design of the plurality of heat exchange plate-shaped tubes 12 is a thin hollow body, they can be manufactured by resin injection molding, thereby improving production efficiency. In addition, the setting of the plurality of spacing walls 122 can ensure that the plurality of heat exchange plate tubes 12 have a better structural durability in the form of a thin, hollow body, It can be ensured to prevent deformation.

In addition, both the distance between the adjacent posts 131 (i.e., the width of the gap 132) and the distance between the adjacent posts 141 (i.e., the width of the gap 142) The two opposing ends of the plurality of heat exchange plate tubes 12 are tightly coupled to the upper grill 13 and the lower grill 14 because they are slightly less than the thickness of the plurality of heat exchange plate tubes 12. [ As a result, it is possible to prevent the second airflow B from leaking from the assembly gap between the plurality of heat exchange plate-like tubes 12 and the upper grill 13 or the lower grill 14.

2, when the plurality of heat exchange plate tubes 12 are assembled to the upper grill 13 and the lower grill 14, the air inlet 113 of the frame 11 is connected to the inlet flow path 1111, And the air exhaust port 114 of the frame 11 communicates with the exhaust flow path 1112 and is connected to the exhaust port 1232 of the second flow path 123 do.

1, the first fan blade 61 is rotated to generate the first airflow A when the drying-wheel dehumidifier 1 is operated. The first airflow A sequentially passes through the first flow path 128 between the plurality of heat exchange plate tubes 12 and the drying wheel 52 and the drying wheel 52 moves moisture from the first airflow A And the drying wheel 52 discharges the dried first airflow A, as shown in Fig. The second fan blades 81 operate to circulate the second airflow B inside the heat exchanger 10 and the circulation air duct 70. When the second airflow B flows through the heater 90 and becomes a high-temperature airflow, the second airflow B will vaporize the moisture inside by driving the drying wheel 52, Thereby restoring the moisture absorbing ability of the liquid. Next, the water vapor together with the second airflow B passes through the plurality of second flow paths 123 in the plurality of heat exchange plate-shaped tubes 12 for heat exchange with the external cold air (for example, the first airflow A) The water vapor is condensed into the water droplets C from the plurality of second flow paths 123 of the plurality of heat exchange plate tubes 12 and the water droplets C are also condensed in the liquid drains (115), and then discharged from the heat exchanger (10). Thus, a dehumidifying effect for the dry-wheel dehumidifier 1 is achieved.

4, the cross section of the heat exchange plate tubes 12 in the above-described embodiment has a width W and a thickness T, and the distance between the two plurality of spacing walls 122 (D) is greater than a thickness (T) and the distance is a predetermined size and may be greater than 4 millimeters (mm), so that a plurality of second flow paths (123) The water droplets condensed in the two flow paths 123 are prevented from being clogged in the inside or preventing smooth discharge. In this embodiment, the thickness T is not limited to the present invention but also depends on the surface tension of the water droplets on the plurality of heat exchange plate tubes 12.

5A, in this embodiment or some other embodiments, the heat exchanger 10 includes not only the openings 1114 of the frame body 111 but also the upper and lower grilles 13 and 14, And an intermediate grill 15 positioned between the upper and lower grills. The middle grill 15 is formed to fix the middle portion of the plurality of heat exchange plate tubes 12 to improve the bonding stability between the plurality of heat exchange plate tubes 12 and the frame body 111. [

Further, in this embodiment or some other embodiments, one end of each of the plurality of heat exchange plate-like tubes 12 near the lower end of the frame 11 is guided by the guiding slope 124, And has an opening 1232 position of each of the plurality of second flow paths 123. Therefore, water droplets can be guided by the design of the guiding slope 124, and water droplets condensed in the plurality of second flow paths 123 can be smoothly discharged.

Moreover, since the external design of the plurality of heat exchange plate-shaped tubes 12 is a thin walled body, the plurality of heat exchange plate-like tubes 12 can be arranged close to each other at appropriate intervals to provide a large heat exchange area in a limited space, Improves performance.
