The invention provides a heat exchange assembly for a humidity exhaust device, which comprises a heat exchange member body 20 arranged in the humidity exhaust device body 1, wherein the heat exchange member body 20 is provided with a cooling part 21 used for containing a cooling medium so as to absorb the heat of damp and hot air contacting with the cooling part 21; the cooling part 21 comprises a cavity and a plurality of clapboards 211; wherein the content of the first and second substances,

the plurality of clapboards 211 are respectively positioned in the cavity, and two adjacent clapboards 211 are respectively connected to two opposite inner side walls of the cavity in a staggered manner; the plurality of clapboards 211 are respectively vertical to the inner wall of one side of the containing cavity; a number of baffles 211 together with the inner contour of the chamber form cooling channels 212 for the passage of a cooling medium. Specifically, the cooling medium is located in the cooling channel 212, when the hot and humid air entering the dehumidifying device body 1 contacts the cooling part 21, the heat of the hot and humid air is transferred to the outer wall of the cooling part 21, the cooling medium in the cooling channel 212 absorbs the heat of the outer wall of the cooling part 21, and then the heat of the hot and humid air is finally transferred to the cooling medium, so as to cool the hot and humid air in the cavity 11. In addition, the partition 211 and the inner contour of the cavity jointly form a cooling channel 212, so that the space of the cooling channel 212 is increased, the retention time of a cooling medium in the cavity is prolonged, and the cooling performance of the cooling medium in the cooling channel 212 is fully utilized; through baffle 211 and the cooling channel 212 that holds the interior profile of chamber and form the curved shape jointly, replace the traditional scheme that adopts curved pipe structure as cooling channel, reduced the space that the interval between two adjacent pipeline sections that traditional pipeline structure is crooked and cause occupy, improved the space size of the cooling channel 212 that same chamber space corresponds promptly, improve the coolant's that cooling portion 21 held the volume for the heat transfer. Two adjacent partition boards 211 are respectively connected to two inner walls of the cavity in a staggered manner. Further, a water inlet end (corresponding to the cooling medium inlet 14 of the housing 10) and a water outlet end (cooling medium outlet) of the cooling channel 212 are respectively located at the outer sides of the two partition plates 211 arranged at the outermost side, so as to fully utilize the space of the cavity, so that the space of the cavity is used for accommodating the cooling medium and the partition plates 211, and the amount of the cooling medium accommodated by the cavity is increased.

In one embodiment, the ends of two adjacent partition plates 211 are staggered in a direction perpendicular to the partition plates 211 to form a cooling channel 212 having a curved shape, so as to form a flow path having a curved shape, so that the flow of the cooling medium is stable and the residence time of the cooling medium in the cooling channel 212 is ensured. In addition, the plurality of partition plates 211 are perpendicular to the outline of one side of the cavity, and the channels formed by two adjacent partition plates 211 and used for containing the cooling medium have the same cross-sectional dimension along the direction perpendicular to the partition plates 211, so that the cooling medium flows smoothly in the channels formed by two adjacent partition plates 211, and the generation of noise caused by turbulent flow due to the change of the size of the inside of the cooling channel is not easy to occur. Because the two adjacent partition boards 211 are respectively connected on the two inner walls opposite to the cavity position in a staggered manner, the cooling medium entering the cavity firstly flows into the first channel connected with the cooling medium inlet end of the cooling channel 212, then flows into the second channel adjacent to the first channel, and then flows into the third channel adjacent to the second channel, and so on, and the arrangement of the plurality of partition boards 211 is reasonable, so that the cooling medium flows stably. The adjacent two channels formed by the plurality of partition plates 211 are in a U shape, so that the flowing stability of the cooling medium is further improved.

In one embodiment, the ends of the plurality of baffles 211 are equally spaced from the corresponding side profiles of the chamber to reduce the difference in flow rate of the cooling medium through the spaces defined by the ends of the different baffles 211 and the side profiles of the chamber.

Further, the distance between two adjacent baffles 211 is equal to the distance between the end of the baffle 211 and the inner wall of the cavity, so as to reduce the influence of the cooling medium flowing to the curve in the cooling channel 212 on the velocity of the cooling medium, so as to avoid causing turbulence.

In one embodiment, the plurality of spacers 211 are arranged at equal intervals. That is, the cross-sectional size of the channel formed between any two adjacent partition plates 211 is uniform, so that the flow velocity of the cooling medium flowing in the cooling channel 212 is uniform or the difference between the flow velocities of the cooling medium flowing through the bend and the flow velocity of the cooling medium flowing in the channel formed by the next two adjacent partition plates 211 is not large, and the noise caused by unstable flow of the cooling medium is reduced.

In yet another embodiment, the spacing between two adjacent partition plates 211 gradually increases toward the cooling medium outlet 213, so that the cooling medium in the cooling channel 212 is discharged from the cooling medium outlet 213 to the cooling channel 212.

Further, the partition 211 is a heat conductive sheet to improve the cooling effect of the cooling portion 21. Specifically, the back on the damp and hot air in cavity 11 transmits heat to cooling portion 21 outer wall, and the heat part on the cooling portion 21 outer wall directly transmits the coolant in cooling channel 212, and the part is passed to earlier and is given baffle 211, and the rethread baffle 211 transmits for coolant for the heat dissipation of the damp and hot air of cooling portion 21 absorption, and then accelerates the absorption of cooling portion 21 outer wall to damp and hot air heat in cavity 11.

In one embodiment, the cooling portion 21 is provided with an opening; opening into the curved cooling channel 212. Because of the moisture removal device body 1 is used for the dryer body, in order to practice thrift the cost and simplify the layout of dryer body inner structure, coolant is the cooling water, and the cooling water is cheap and take the convenience, can in time provide the cooling water to moisture removal device body 1 through this internal water route of dryer, need not to change coolant, simple operation.

Further, the outer contour of the opening of the cooling portion 21 abuts against the inner wall of the casing 10 of the dehumidifying apparatus body 1 to form a closed cooling channel 212, so as to prevent the cooling medium inside the cooling channel 212 from leaking. Furthermore, the cooling portion 21 is open to form the opening, and the outline of the opening is large, so that the scale in the cooling channel can be observed and cleaned conveniently; and when the heat exchange member 20 is installed, the open end of the cooling part 21 abuts against the inner wall of the casing 10, and the cooling medium in the cooling channel 212 does not overflow the cooling channel 212. It should be understood that when a gap is left between the outer contour of the opening of the cooling portion 21 and the inside of the housing 10, the cooling portion 21 is placed in an opening direction in order to prevent the cooling medium in the cooling passage 212 from leaking from the opening thereof.

Further, the height of the partition 211 is smaller than the height of the peripheral outline of the receiving cavity, so as to facilitate the processing of the cooling portion 21 and reduce the requirement for the processing accuracy of the partition 211, so that the height of the partition 211 is higher than the height of the peripheral outline of the receiving cavity during the processing, which affects the outer outline of the opening of the cooling portion 21 against the inner wall of the housing 10, and further the cooling channel 212 cannot be closed, when the cooling medium in the cooling channel 212 is more or flows more rapidly, the cooling medium in the cooling channel 212 is likely to leak from the gap between the outer outline of the opening of the cooling portion 21 and the inner wall of the housing 10.

In one embodiment, the heat exchange member 20 includes a plurality of air channels 22 for receiving hot and humid air. The air passage 22 is used to guide the flow of hot and humid air, so that the hot and humid air entering the air passage 22 contacts the cooling part 21 for cooling. Further, the air channel 22 is formed by a plurality of fins 23 or a plurality of ejector pins, and the fins 23 have certain thermal conductivity and function to assist heat dissipation of the hot and humid air in the air channel 22. When the cooling portion 21 is located above or beside the air channel 22, the opening below the air channel 22 formed by the fins 23 or the ejector pins is beneficial to removing condensed water formed by condensing the damp-heat air in the air channel 22 in the cooling process, and the condensed water falls onto the inner wall of the casing 10 from the opening below the air channel 22 and is discharged out of the dehumidifying device body 1 from the water outlet 15 on the casing 10 corresponding to the position.

In one embodiment, the plane of the partition 211 intersects the plane of the air passageway 22. Specifically, the number of the air passages 22 is several, and the plane of the partition 211 intersects the plane of the air passages 22, so that the number of the cooling passages 212 corresponding to each air passage 22 is increased, and the heat exchange efficiency between the cooling medium in the passages of the cooling passages 212 and the hot and humid air in each air passage 22 is improved.

When the temperature of the air in the clothes drying cylinder is reduced to the temperature threshold set by the temperature and humidity sensor at the air inlet 12, the air inlet valve is opened, part of the hot and humid air in the clothes drying cylinder enters the condenser, and part of the hot and humid air enters the dehumidifying device body 1, the hot and humid air generated in the clothes drying cylinder is processed through the condenser and the dehumidifying device body 1 simultaneously, and the drying process is accelerated; at this time, since the temperature of the hot and humid air in the drying cylinder is already reduced, the amount of heat absorbed by the cooling water after the hot and humid air enters the dehumidifying device body 1 is reduced, the temperature of the cooling water after absorbing the heat of the hot and humid air is increased to some extent, but the increase range is not high, and the temperature difference with the hot and humid air generated at this time of the drying cylinder is still large, the cooling water after absorbing the heat in the dehumidifying device body 1 can still cool the hot and humid air in the condenser after being discharged into the condenser from the water discharge port 15, and a certain cooling speed is ensured. A part of hot and humid air generated by the clothes drying cylinder is introduced into the cavity 11 of the dehumidifying device body 1 for cooling and dehumidifying treatment, and a part of hot and humid air is introduced into the condenser for condensing, dehumidifying and recovering the dried air, so that the treatment speed of the hot and humid air with higher temperature generated by the clothes drying cylinder is improved, and in addition, the cooling water provided by the water inlet valve of the clothes dryer body is secondarily utilized, so that the water is saved. In one embodiment, the condenser further comprises a medium inlet (not shown) connected to a water inlet valve in the dryer body for introducing cooling water to increase the cooling rate of the condenser.

In still another embodiment, the drain port 15 communicates with a dryer body drain pipe to drain condensed water generated from the dehumidifying apparatus body 1 outside the dryer body. In still another embodiment, a collecting box communicated with the drain port 15 is provided in the dryer body to collect the condensed water generated from the dehumidifying apparatus body 1.

Compared with the prior art, the heat exchange piece of the dehumidifying device provided by the invention has the advantages that the space for accommodating the cooling medium in the extended cooling channel is increased, the contact area between the cooling medium and the heat exchange surface of the cooling channel is increased, and the heat exchange effect with the damp and hot air is improved.

The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner; those skilled in the art can readily practice the invention as shown and described in the drawings and detailed description herein; however, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the invention as defined by the appended claims; meanwhile, any changes, modifications, and evolutions of the equivalent changes of the above embodiments according to the actual techniques of the present invention are still within the protection scope of the technical solution of the present invention.
