When the upper shell 11 and the lower shell 13 are installed, the cooling medium inlet 111 is located between the vertical upper fin 1211 and the second baffle 1242, and the cooling medium enters the water channel from the cooling medium inlet 111, because the upper fin 1211 is vertical relative to the first baffle 2141 or the third baffle 1243, the cooling medium inlet 111 is located between the vertical upper fin 1211 and the second baffle 1242, so that the axis of the cooling medium inlet 111 is parallel to the plane of the upper fin 1211, and the cooling medium enters the water channel structure through the cooling medium inlet 111, and can rapidly circulate in the water channel, thereby increasing the circulation rate of the cooling medium and improving the heat exchange efficiency between the cooling medium and the heat conducting plate 123.

The upper fins 1211 are arranged in parallel with each other and are cross-connected to the first baffle 1241 and the opposite third baffle 1243, so that the area of the water passage can be increased, the contact area between the cooling medium and the heat conducting plate 123 can be increased, referring to fig. 5, all the parts of the heat conducting plate 123 are in contact with the cooling medium, and the design of the plate-shaped structure of the upper fins 1211 without bending reduces the manufacturing cost.

The air path structure 122 includes: the air duct comprises a plurality of lower fins 1221 and a partition 1222, wherein at least two lower fins 1221 are arc-shaped lower fins, and arc-shaped air ducts are formed between the adjacent arc-shaped lower fins.

Each of the lower fins 1221 is arc-shaped, and an air duct is formed between two adjacent lower fins 1221, and preferably, the air duct is also arc-shaped.

The lower fin is fixed to the heat conducting plate 123 of the outlet module 12, and the heat conducting plate 123 is provided with a drain 1231. Baffle 1222 is the heat-conducting plate and extends along the direction that deviates from the wind path structure, and is located the border of outlet, partly encloses outlet 1231.

Preferably, in the present embodiment, since the heat conductive plate 123 is substantially square, the size of each of the plurality of lower fins 1221 is different. Specifically, the lower fins 1221 are equally spaced, that is, the widths of the water channels formed by the lower fins 1221 are the same. The radians of the lower fins 1221 are all the same, so that the lower fins 1221 are parallel to each other, and the radians are 10 to 90 degrees.

Specifically, referring to fig. 2, the lower fin 1221 includes a root 12211 and an end 12212, the root 12211 is fixed to the heat conducting plate 123 in the air outlet module 12, and the end 12212 abuts against the lower housing 13 of the air outlet module 12. Preferably, the thickness of the root 12211 is greater than the thickness of the end 12212. The material is saved while the structural strength is ensured.

Preferably, the inner arc of the lower fin 1221 faces the air inlet 132 of the air outlet module 12, so that the air entering the air duct from the air inlet 132 hits the lower fin 1221 and then enters each air duct, the contact area of the air is increased, and the cooling speed of the hot and humid air is increased.

Preferably, in the present embodiment, referring to fig. 3, the number of the lower fins 1221 is 7, wherein the inner arc of the first lower fin faces the air inlet 132 of the air outlet module 12, and the air duct formed between the sixth lower fin and the seventh lower fin faces the air outlet 131.

The air outlet 131 is provided with a semicircular blocking piece, so that the shape of the air outlet 131 is semicircular, and the blocking piece is positioned at the bottom of the air outlet 131 to prevent water from being discharged.

The heat conductive plate 123 is made of a heat conductive material, such as metal and alloy. The upper shell 11 and the lower shell 13 are made of plastic or metal.

The air inlet 132 is higher than the air outlet 131, and the air inlet 132 is larger than the air outlet 131, so as to avoid turbulence of the air flow. The cooling medium outlet 133 is far lower than the cooling medium inlet 111, and the condensed water is discharged at the same time, so as to prevent the moisture of the air outlet module 12 from increasing due to the excessive content of the condensed water in the air outlet module 12, which is not favorable for dehumidifying the damp and hot air.

Referring to fig. 7 and 8, the lower case 13 includes a side wall and a bottom, the bottom being an inclined bottom, and the cooling medium outlet 133 being located at the inclined bottom.

A transition bevel 137 is also provided between the sidewall and the second bevel 135.

The cooling medium outlet 133 is located at the second inclined surface 135.

Due to the design of the first inclined plane 134, the second inclined plane 135, the third inclined plane 136 and the transition inclined plane 137, the cooling medium outlet 133 is far lower than the cooling medium inlet 111, and the cooling medium is discharged in time, so as to prevent the excessive content of the condensed water in the air outlet module 12, and simultaneously prevent the condensed water from being accumulated at the bottom, which results in the increase of the humidity of the air outlet module 12 and is not beneficial to the dehumidification of the damp and hot air.

And due to the structures and the position designs of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136 and the transition inclined surface 137, the structure of the lower shell 13 is smoother, and the noise of the cooling medium in the heat exchange assembly 10 is reduced.

The air inlet 132 and the air outlet 131 are located on two adjacent side walls. The cambered surfaces of the lower fins 1221 face the air inlets 132, so that air entering the air channels from the air inlets 132 collides with the lower fins 1221 and then enters each air channel, the contact area of the air is increased, and the cooling speed of the damp and hot air is increased. Due to the arc-shaped design of the lower fins 1221, the air outlet 131 is located on the side wall adjacent to the air inlet 132.

Specifically, the upper casing 11 is further provided with a mounting portion 112 for mounting the whole heat exchange assembly 10 inside the clothes drying apparatus. Four lower fixing portions 138 are provided at four corners in the lower case 13, the lower fixing portions 138 abut against the heat conductive plate 123, the lower fixing portions 138 are provided with screw holes, and screws or bolts are mounted in the mounting holes 1233 on the heat conductive plate 123 and the screw holes of the lower fixing portions 138.

The upper housing 11 is further provided with an upper fixing portion 113, and the upper fixing portion 113 is a threaded hole. Preferably, the baffle 124 is provided with a mounting groove corresponding to the upper fixing portion 113. The air outlet module 12 is fixedly mounted on the fixing portion 138 of the lower casing 13 by passing through the mounting hole 1233 through a bolt or a screw, the baffle plate 124 protrudes out of the lower casing 13, and then the upper casing 11 is fastened, and the upper casing 11 is screwed on the baffle plate 124 through the upper fixing portion 113.

After the upper housing 11 and the lower housing 13 are installed, the cooling medium inlet 111 is located between the baffle 124 and the upper fins 1211, the air inlet 132 is higher than the air outlet 131, and the cooling water enters the water channel structure 121 through the cooling medium inlet 111, flows into each water channel after being impacted by the upper fins 1211, cools the hot and humid air in the air channel structure 122 through the heat conduction effect of the heat conduction plate 123, a large amount of cooling water flows into the lower housing 13 through the water outlet 1231, and a small amount of cooling water flows into the lower housing 13 through the through holes 1232 and is discharged from the cooling medium outlet 133 at the bottom of the lower housing 13. Meanwhile, the hot and humid air exhausted from the clothes drying apparatus enters the air path structure 122 through the air inlet 132, flows into each air path after being impacted by the lower fins 1221, is cooled to be low-temperature air by the heat conducting plate 123, and is exhausted from the air outlet 131.

In short, the cooling medium enters the water path structure 121 from the cooling medium inlet, and the cooling medium takes away the heat of the heat conducting plate 123 and flows out from the cooling medium outlet 133 at the bottom of the lower housing 13.
