Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a heat exchange component for a dehumidification device, a dehumidification device, and a clothes dryer. Background Technology

[0002] As people's living standards improve, users' requirements for dryers go beyond just washing. Due to weather factors, such as the rainy season, clothes take a long time to dry after washing, so some users also need dryers that can dry clothes completely.

[0003] Currently, clothes dryers on the market heat air using a heater, and then a fan circulates this hot air into the drying drum. The hot air removes moisture from the surface or inside of damp clothes, thus drying them. The resulting humid air is then expelled from the inner drum's vent. Directly expelling this humid air outside the dryer would significantly impact the humidity and temperature of the surrounding environment. Existing dryers now dehumidify and cool the humid air, typically using cooling water. To maintain a certain cooling effect, the cooling channels used in these dryers are often designed with curved structures, which takes up considerable space. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a heat exchange component for a dehumidification device, which increases the space of the cooling channel while reducing the space occupied by the cooling channel in the cooling section, thus facilitating the miniaturization design of the cooling section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] The present invention provides a heat exchange component for a dehumidification device, comprising a heat exchanger body disposed within the dehumidification device body, the heat exchanger body having a cooling section for containing a cooling medium to absorb heat from humid air in contact with the cooling section; the cooling section includes a cavity and a plurality of partitions; wherein the plurality of partitions are respectively located within the cavity;

[0007] The adjacent partitions are respectively staggered and connected to the two opposite inner walls of the cavity; the plurality of partitions are respectively perpendicular to one inner wall of the cavity;

[0008] Several of the baffles together with the inner contour of the cavity form a cooling channel for the passage of the cooling medium.

[0009] Preferably, the ends of two adjacent partitions are staggered in a direction perpendicular to the partition.

[0010] Preferably, the distance between the ends of the partitions and the side contours corresponding to the positions of the cavities is equal.

[0011] Preferably, several partitions are arranged at equal intervals.

[0012] Preferably, the spacing between two adjacent baffles gradually increases in the direction toward the cooling medium outlet.

[0013] Preferably, the cooling section has an opening; the opening faces the curved cooling channel.

[0014] Preferably, the outer contour of the cooling section opening abuts against the inner wall of the housing of the dehumidification device body to form a closed cooling channel.

[0015] Preferably, the height of the partition is less than the height of the periphery of the cavity.

[0016] Preferably, the heat exchanger includes several air channels for containing hot and humid air.

[0017] Preferably, the plane containing the partition intersects with the plane containing the air passage.

[0018] A second objective of this invention is to provide a dehumidification device, comprising a dehumidification device body disposed within a dryer body for condensation dehumidification, wherein the dehumidification device body comprises:

[0019] The shell has a cavity for accommodating the heat exchanger body;

[0020] The heat exchanger body as described above;

[0021] The hot and humid air generated by the drying drum of the dryer body enters the cavity and comes into contact with the heat exchanger body. The cooling medium in the cooling channel absorbs the heat of the hot and humid air. After cooling, the hot and humid air is condensed and dehumidified. The dehumidified air is discharged from the air outlet of the dehumidification device body to the outside of the dryer body.

[0022] Preferably, the dehumidification device body is provided with a partition for dividing the cavity into two regions; the cooling section and the humid air are respectively located on both sides of the partition.

[0023] Preferably, the first wall periphery of the cooling section facing the humid air abuts against the cavity profile to form the separator.

[0024] Preferably, the cooling section is located above the air passage of the heat exchanger body.

[0025] A third object of the present invention is to provide a clothes dryer including a clothes dryer body for performing drying, the clothes dryer body including a dehumidification device body as described above.

[0026] Preferably, the dryer body includes a condenser; the drain outlet of the dehumidification device body is connected to the condenser to introduce water into the condenser as a cooling medium.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This invention provides a heat exchange component for a dehumidification device. The cooling section of the heat exchanger body is disposed within a cavity of the cooling section via several partitions. These partitions, together with the inner contour of the cavity, form cooling channels. This increases the space available for accommodating the cooling medium within the cooling channels, thereby increasing the contact area between the cooling medium and the cooling channels, improving the heat exchange effect with humid air, and controlling the space occupied by the cooling channels within the heat exchanger body, which is beneficial for miniaturization of the cooling section. All partitions are perpendicular to one side of the cavity contour, and the channels formed by adjacent partitions have the same cross-section, ensuring smooth flow of the cooling medium within the cooling channels and reducing noise generation. Furthermore, the partitions are arranged at equal intervals so that when the cooling medium flows through the cooling channels, turning from one channel to the next, it does not cause turbulence due to differences in the size of adjacent channels, further reducing noise generation.

[0029] This invention provides a dehumidification device. The device body cools the hot and humid air generated by the clothes dryer drum, lowering the temperature of the hot and humid air while condensing the moisture in the air into condensate, which is then removed. The cooled and dehumidified air is then discharged into the external environment of the clothes dryer, avoiding the direct discharge of the hot and humid air generated by the clothes dryer drum into the external environment, thus preventing an increase in ambient temperature and humidity and avoiding environmental pollution. By discharging the cooled and dehumidified hot and humid air from the clothes dryer drum outside the dryer, the dehumidified air does not need to be recirculated, accelerating the drying process. Furthermore, the dehumidification device body can work in conjunction with a condenser to continuously cool and dehumidify the hot and humid air generated by the clothes dryer drum.

[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0042] Example 1

[0043] This invention provides a heat exchange component for a dehumidification device, such as... Figure 1 , Figure 2As shown, the device includes a heat exchanger body 20 disposed within the dehumidification device body 1. The heat exchanger body 20 is provided with a cooling section 21 for containing a cooling medium to absorb heat from the humid air in contact with the cooling section 21. The cooling section 21 includes a cavity and several partitions 211.

[0044] Several partitions 211 are located within the cavity, with adjacent partitions 211 being staggered and connected to opposite inner walls of the cavity. The partitions 211 are perpendicular to one inner wall of the cavity. The partitions 211 and the inner contour of the cavity together form a cooling channel 212 for the passage of the cooling medium. Specifically, the cooling medium is located within the cooling channel 212. When the humid air entering the dehumidification device body 1 comes into contact with the cooling section 21, the heat of the humid air is transferred to the outer wall of the cooling section 21. The cooling medium within the cooling channel 212 absorbs the heat from the outer wall of the cooling section 21, thus ultimately transferring the heat of the humid air to the cooling medium to cool the humid air within the cavity 11. Furthermore, the partition 211, together with the inner contour of the cavity, forms a cooling channel 212, increasing the space of the cooling channel 212, extending the residence time of the cooling medium in the cavity, and fully utilizing the cooling performance of the cooling medium in the cooling channel 212. The partition 211, together with the inner contour of the cavity, forms a curved cooling channel 212, replacing the traditional curved pipe structure as the cooling channel. This reduces the space occupied by the spacing between adjacent pipe sections caused by the curvature of the traditional pipe structure, thus increasing the size of the cooling channel 212 corresponding to the same cavity space, increasing the amount of cooling medium accommodated in the cooling section 21, and accelerating heat exchange. Adjacent partitions 211 are staggered and connected to the two inner walls of the cavity at opposite positions. Further, the water inlet (corresponding to the cooling medium inlet 14 of the shell 10) and water outlet (cooling medium outlet) of the cooling channel 212 are located outside the two outermost partitions 211, respectively, to fully utilize the cavity space, allowing the cavity space to accommodate the cooling medium and several partitions 211, increasing the amount of cooling medium accommodated in the cavity.

[0045] In one embodiment, the ends of two adjacent baffles 211 are staggered along a direction perpendicular to the baffles 211 to form a curved cooling channel 212, thereby creating a curved flow path. This ensures stable flow of the cooling medium and guarantees the residence time of the cooling medium within the cooling channel 212. Furthermore, several baffles 211 are perpendicular to one side of the cavity profile, and the cross-sectional dimensions of the channels formed by adjacent baffles 211 for accommodating the cooling medium are consistent along a direction perpendicular to the baffles 211. This ensures smooth flow of the cooling medium within the channels formed by adjacent baffles 211, preventing turbulence and noise caused by changes in the size of the cooling channels. Because adjacent baffles 211 are staggered and connected to the two inner walls of the cavity at opposite positions, the cooling medium entering the cavity first flows into the first channel connected to the cooling medium inlet end of the cooling channel 212, then into the second channel adjacent to the first channel, then into the third channel adjacent to the second channel, and so on. The arrangement of the baffles 211 is reasonable, ensuring stable flow of the cooling medium. The adjacent channels formed by several baffles 211 are U-shaped, which further improves the stability of the cooling medium flow.

[0046] In one embodiment, the distance between the ends of several baffles 211 and the side contours corresponding to the cavity positions is equal, so as to reduce the flow rate difference of the cooling medium when passing through the space formed by the ends of different baffles 211 and the side contours of the cavity.

[0047] Furthermore, the spacing 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 impact of the cooling medium on the speed of the cooling medium when it flows to the bend in the cooling channel 212, so as to avoid causing turbulence.

[0048] In one embodiment, a plurality of partitions 211 are arranged at equal intervals. That is, the cross-sectional size of the channel formed between any two adjacent partitions 211 is the same, so that when the cooling medium flows in the cooling channel 212, the flow velocity remains the same or not much different when it passes through the bend and enters the channel formed by the next two adjacent partitions 211, thereby reducing the noise caused by unstable flow of the cooling medium.

[0049] In another embodiment, the spacing between two adjacent partitions 211 gradually increases in the direction toward the cooling medium outlet 213, so that the cooling medium in the cooling channel 212 can be discharged from the cooling medium outlet 213 into the cooling channel 212.

[0050] Furthermore, the partition 211 is a heat-conducting plate to improve the cooling effect of the cooling section 21. Specifically, after the humid and hot air in the cavity 11 transfers heat to the outer wall of the cooling section 21, part of the heat on the outer wall of the cooling section 21 is directly transferred to the cooling medium in the cooling channel 212, and part is first transferred to the partition 211, and then transferred to the cooling medium through the partition 211, thereby accelerating the dissipation of heat from the humid and hot air absorbed by the cooling section 21, and thus accelerating the absorption of heat from the humid and hot air in the cavity 11 by the outer wall of the cooling section 21.

[0051] In one embodiment, the cooling section 21 has an opening facing the curved cooling channel 212. Since the dehumidification device body 1 is used in the dryer body, to save costs and simplify the internal structure layout of the dryer body, cooling water is used as the cooling medium. Cooling water is inexpensive and readily available; it can be supplied to the dehumidification device body 1 promptly through the water passages within the dryer body without needing to replace the cooling medium, making operation convenient. The cooling water absorbs heat and its temperature rises. Because the water used in the dryer body typically contains calcium and magnesium ions, which are prone to scaling, scale may form during the temperature rise of the cooling water. The opening in the cooling section allows for monitoring scale formation and timely cleaning.

[0052] Furthermore, the outer contour of the opening of the cooling section 21 abuts against the inner wall of the housing 10 of the dehumidification device body 1 to form a closed cooling channel 212, preventing leakage of the cooling medium inside the cooling channel 212. Furthermore, the cooling section 21 is open-shaped to form the opening, with a large opening contour for easy observation and cleaning of scale inside the cooling channel; and when the heat exchanger 20 is installed, the open end of the cooling section 21 abuts against the inner wall of the housing 10, preventing the cooling medium inside the cooling channel 212 from overflowing. It should be understood that when a gap is left between the outer contour of the opening of the cooling section 21 and the interior of the housing 10, the opening of the cooling section 21 is positioned facing away from the inside to prevent leakage of the cooling medium inside the cooling channel 212.

[0053] Furthermore, the height of the partition 211 is less than the height of the periphery of the cavity, so as to facilitate the processing of the cooling section 21 and reduce the requirements for the processing accuracy of the partition 211. This is to prevent the height of the partition 211 from being higher than the height of the periphery of the cavity during processing, which would affect the outer contour of the opening of the cooling section 21 from abutting against the inner wall of the housing 10, thus making it impossible to seal the cooling channel 212. When there is a lot of cooling medium in the cooling channel 212 or the flow is rapid, it is easy to cause the cooling medium in the cooling channel 212 to leak from the gap between the outer contour of the opening of the cooling section 21 and the inner wall of the housing 10.

[0054] In one embodiment, the heat exchanger 20 includes several air channels 22 for containing hot and humid air. The air channels 22 guide the flow of hot and humid air, facilitating contact between the hot and humid air entering the air channels 22 and the cooling section 21 for cooling. Further, the air channels 22 are formed by several fins 23 or several pins. The fins 23 have a certain thermal conductivity, serving to assist in the dissipation of heat from the hot and humid air within the air channels 22. When the cooling section 21 is located above or to the side of the air channels 22, the lower opening of the air channels 22 formed by the fins 23 or pins facilitates the removal of condensate formed during the cooling process of the hot and humid air within the air channels 22. The condensate falls from the lower opening of the air channels 22 onto the inner wall of the housing 10, and then is discharged from the corresponding drain outlet 15 on the housing 10 outside the dehumidification device body 1.

[0055] In one embodiment, the plane of the partition 211 intersects the plane of the air channel 22. Specifically, there are several air channels 22, and the intersection of the plane of the partition 211 and the plane of the air channel 22 increases the number of cooling channels 212 corresponding to each air channel 22, thereby improving the heat exchange efficiency between the cooling medium in each cooling channel 212 and the humid and hot air in each air channel 22.

[0056] Example 2

[0057] This invention provides a dehumidification device, including a dehumidification device body 1 disposed within the dryer body, such as... Figure 1 , Figure 2 , Figure 3 As shown, the dehumidification device body 1 includes:

[0058] The housing 10 has a cavity 11 for accommodating the heat exchanger 20 and a temporary storage space for forming hot and humid air. After the hot and humid air enters the cavity 11, the flow speed of the hot and humid air is reduced due to the constraint of the cavity 11 contour, so that the hot and humid air temporarily accumulates in the cavity 11 to contact the heat exchanger 20 in the cavity 11.

[0059] The heat exchanger 20, as described above, is used to absorb heat from the humid air inside the cavity 11. The humid air generated by the drying drum of the dryer body enters the cavity 11. The cooling medium in the cooling channel 212 absorbs the heat from the humid air, which is then condensed and dehumidified. The dehumidified air is then discharged from the outlet of the dehumidification device 1 to the outside of the dryer body. Specifically, as... Figure 4As shown, the housing 10 is provided with an air inlet 12 and an air outlet 13. The air inlet 12 is connected to the drying drum, and the air outlet 13 is connected to the external environment of the dryer body. After the dryer body starts the drying program, the heater of the dryer body heats the air entering the drying drum. The heated air causes the moisture contained in the clothes in the drying drum to evaporate, forming an airflow containing water molecules. Under the guidance of the fan of the dryer body, the airflow containing water molecules mixes with the hot air in the drying drum, forming humid and hot air with relatively high temperature and humidity. The humid and hot air generated by the drying drum enters the cavity 11 through the air inlet 12 and comes into contact with the cooling part 21 of the heat exchanger 20 located in the cavity 11 to be cooled. During the cooling process, the humid and hot air forms condensate to dehumidify. The cooled and dehumidified air is discharged to the external environment of the dryer body, reducing the impact on the temperature and humidity of the environment where the dryer body is located and avoiding environmental pollution; and timely discharge of the humid and hot air in the drying drum speeds up the drying process of the dryer body. Furthermore, by limiting the heat absorption performance of the cooling section 21, the temperature and humidity of the air discharged from the dehumidification device body 1 into the external environment of the dryer body can be controlled. For example, the temperature of the air discharged from the dryer body can be controlled to be slightly lower than the room temperature, and the humidity can be controlled to a comfortable level. In hot seasons, the temperature of the environment around the dryer body can also be appropriately adjusted to improve the user experience. The cooling medium inlet 14 of the housing 10 is connected to the cooling channel 212 to allow the cooling medium to enter. The cooling medium that has undergone heat exchange with the humid and hot air in the cooling channel 212 is then discharged outside the housing 10. It can be discharged through the cooling medium outlet connected to the cooling channel 212 provided in the housing 10, or it can be discharged through the drain outlet 15 after being collected with condensate.

[0060] In one embodiment, the dehumidification device body 1 is provided with a partition to divide the cavity 11 into two regions; the cooling section 21 and the humid hot air are located on opposite sides of the partition, so that the cooling section 21 and the humid hot air entering the cavity 11 are located in two relatively independent spaces, to prevent the humid hot air from forming condensate during the cooling process, which would cause excessive moisture to come into contact with the outer wall of the cooling section 21, thus hindering the cooling section 21 from absorbing heat from the humid hot air. Further, in one embodiment, the heat exchanger 20 includes an air channel 22 for containing the humid hot air; the cooling section 21 and the air channel 22 of the heat exchanger 20 are located on opposite sides of the partition, so that the cooling section 21 and the air channel 22 are located in two relatively independent spaces. Specifically, the condensation formed by the cooling and condensation of the hot and humid air in the air channel 22 will increase the humidity of the space where the air channel 22 is located to a certain extent, thus separating the cooling section 21 from the air channel 22. The increase in humidity in the air channel 22 will not affect the humidity of the environment where the cooling section 21 is located, so as to prevent the increased humidity of the environment where the cooling section 21 is located from causing more water molecules to come into contact with the outer wall of the cooling section 21. The cooling section 21 will absorb the heat of the water molecules in contact with its outer wall, thereby affecting the cooling effect of the cooling section 21.

[0061] Furthermore, the periphery of the first wall 214 of the cooling section 21 facing the humid air abuts against the contour of the cavity 11 to form a partition. Specifically, the periphery of the first wall 214 of the cooling section 21 facing the air passage 22 abuts against the contour of the cavity 11 to form a partition, eliminating the need for additional partitions and saving space within the cavity 11. Furthermore, the two sides of the first wall 214 respectively contact the cooling medium in the cooling passage 212 and the humid air in the air passage 22. The first wall 214 is a heat-conducting plate to form the heat exchange surface of the cooling passage 212, thereby increasing the speed at which heat from the humid air is transferred to the cooling medium in the cooling passage 212 and accelerating the heat exchange efficiency. Furthermore, the first wall 214 is provided with a plurality of mounting holes 2141, and the cavity 11 is provided with a plurality of mounting portions 111 corresponding to the positions of the mounting holes 2141, so as to fix the heat exchanger 20 within the cavity 11 by fasteners.

[0062] In one embodiment, the cooling section 21 is located above the air passage 22. The condensate formed during the cooling process of the humid and hot air in the air passage 22 falls under its own gravity and does not come into contact with the first wall 214, which serves as a heat exchanger, so as to prevent the condensate from accumulating on the first wall 214 and affecting its absorption of heat from the humid and hot air.

[0063] In one embodiment, the space occupied by the cooling section 21 in the cavity 11 is one-third to one-half of the space occupied by the air channel 22 in the cavity 11, so as to increase the height of the air channel 22, increase the amount of humid and hot air that the air channel 22 can accommodate, and the humid and hot air can be dispersed in the air channel 22, so as to prevent the space of the air channel 22 from being too small, which would cause the humid and hot air to accumulate in the air channel 22 and be detrimental to the heat transfer of the humid and hot air.

[0064] In one embodiment, the drain outlet 15 of the housing 10 is located on the bottom wall of the housing 10. The condensate formed by the humid and hot air in the air channel 22 during the cooling process falls onto the bottom wall inside the housing 10 and is discharged from the drain outlet 15. This facilitates the discharge of condensate and prevents excessive condensate from accumulating in the cavity 11, which would affect the humidity inside the cavity 11 and thus affect the cooling effect of the cooling section 21.

[0065] In one embodiment, the housing 10 includes a first housing 16 and a second housing 17; the first housing 16 and the second housing 17 together clamp to form a cavity 11. The first housing 16 and the second housing 17 are detachably connected to facilitate the loading and unloading of the heat exchanger 20.

[0066] Example 3

[0067] This invention provides a clothes dryer, including a dryer body for performing drying, the dryer body including a dehumidification device body 1 as described above. The dryer body includes a cabinet and a drying drum; both the drying drum and the dehumidification device body 1 are disposed inside the cabinet, and the air outlet 13 of the dehumidification device body 1 is unidirectionally connected to the external environment of the cabinet, for discharging the cooled and dehumidified humid air in the cavity 11 outside the cabinet. When the dryer body performs the drying program, the humid air from the drying drum is introduced into the cavity 11 through the air inlet 12, and after being cooled by the cooling section 21, the moisture in the humid air is condensed and removed, and then discharged outside the cabinet through the air outlet 13. By using the dehumidification device body 1, the humid air generated by the drying drum is cooled and dehumidified before being discharged into the external environment, thus avoiding the direct discharge of the humid air generated by the drying drum into the cabinet, which would lead to an increase in the humidity and temperature of the external environment, affecting the external environmental parameters of the dryer body, resulting in a poor user experience, and is also detrimental to the preservation of furniture located in the same environment.

[0068] Furthermore, the dryer body also includes a heater and a fan. The heater is used to heat the air, and the fan is used to introduce the dried air heated by the heater into the drying drum to dry the clothes inside the drying drum.

[0069] In one embodiment, the cooling medium is cooling water, the cooling medium inlet 14 of the dehumidification device body 1 is connected to the water inlet valve inside the dryer body to introduce cooling water; the drain outlet 15 of the dehumidification device body 1 is connected to the drain pipe of the dryer body.

[0070] In one embodiment, the dryer body includes a condenser; the drain outlet 15 of the dehumidification device body 1 is connected to the condenser to guide the cooling water discharged from the drain outlet 15 into the condenser as a cooling medium. Specifically, the condenser is used to condense the hot and humid air entering the dryer drum into dry air to form dry air, which is then supplied to the heater inside the dryer body. The dry air is heated by the heater and then introduced into the dryer drum to continue drying the clothes, thereby dehumidifying the hot and humid air generated in the dryer drum and recycling the dry air. In one embodiment, the cooling water that has absorbed the heat of the hot and humid air discharged from the outlet of the cooling channel 212 falls onto the bottom wall inside the housing 10, collects with the condensate, and is discharged from the drain outlet 15. The drain outlet 15 of the dehumidification device body 1 is connected to the condenser to introduce the cooling water that has absorbed the heat of the hot and humid air inside the dehumidification device body 1 and the condensate as the cooling medium of the condenser. Furthermore, to save energy and speed up drying, an air inlet valve and a temperature and humidity sensor are installed at the air inlet 12 of the dehumidification device body 1. When the dryer body is performing drying, the condenser and water inlet valve are opened first, and cooling water is introduced into the cooling medium inlet 14. At this time, the hot and humid air from the drying drum only enters the condenser; the water inlet valve of the dryer body introduces cooling water into the cooling section 21 of the dehumidification device body 1. At this time, no hot and humid air generated by the drying drum is introduced into the dehumidification device body 1, and the water in the dehumidification device body 1 is discharged from the drain outlet 15 into the condenser to cool and dehumidify the hot and humid air generated by the drying drum introduced into the condenser. When the temperature of the air inside the dryer drops 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 inside the dryer enters the condenser, and part enters the dehumidification device body 1. The condenser and the dehumidification device body 1 simultaneously process the hot and humid air generated inside the dryer, accelerating the drying process. At this time, since the temperature of the hot and humid air inside the dryer has decreased, the amount of heat absorbed by the cooling water after the hot and humid air enters the dehumidification device body 1 is reduced. The temperature of the cooling water after absorbing the heat of the hot and humid air increases, but the increase is not significant. The temperature difference between the cooling water and the hot and humid air generated in the dryer at this time is still large. Therefore, the cooling water that has absorbed heat in the dehumidification device body 1 is discharged from the drain outlet 15 into the condenser, which can still cool the hot and humid air in the condenser and ensure a certain cooling rate. Part of the hot, humid air generated by the dryer is introduced into the cavity 11 of the dehumidification device body 1 for cooling and dehumidification, while another part is introduced into the condenser for condensation, dehumidification, and recovery of dry air, thereby increasing the processing speed of the high-temperature hot, humid air generated by the dryer. Furthermore, the cooling water supplied by the water inlet valve of the dryer body is reused, saving water. In one embodiment, the condenser also includes a medium inlet (not shown in the figure), connected to the water inlet valve inside the dryer body, to introduce cooling water and improve the cooling speed of the condenser.

[0071] In another embodiment, the drain outlet 15 is connected to the drain pipe of the dryer body to discharge the condensate generated by the dehumidification device body 1 outside the dryer body. In yet another embodiment, the dryer body is provided with a collection box connected to the drain outlet 15 to collect the condensate generated by the dehumidification device body 1.

[0072] Compared with the prior art, the present invention provides a heat exchange component for a dehumidification device, which increases the space of the extended cooling channel to accommodate the cooling medium, thereby increasing the contact area between the cooling medium and the heat exchange surface of the cooling channel and improving the heat exchange effect with humid and hot air.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
