Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a heat exchange element for a moisture removal device, a moisture removal device, and a clothes dryer. Background Art

[0002] As people's living standards improve, users' requirements for dryers are not just for washing. Due to weather factors, such as the rainy season, it takes a long time for clothes to dry after washing, and some users also need dryers that can dry clothes.

[0003] Current clothes dryers use a heater to generate hot air, which is then drawn into the dryer drum by a fan. This hot air removes moisture from the surface or interior of damp clothing, drying the clothes. The resulting hot and humid air is then discharged through the inner drum outlet. Directly discharging this hot and humid air outside the dryer significantly affects the humidity and temperature of the environment in which the dryer is located. Existing dryers dehumidify and cool this hot and humid air, including by using a cooling medium. Improving this cooling efficiency is a current technical challenge facing this field. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a heat exchanger for a dehumidification device, and a cooling channel is provided with a plurality of holes to realize that the cooling part cools the hot and humid air in two ways. One way is to allow the cooling medium flowing into the cavity from the plurality of holes to directly contact the hot and humid air to absorb the heat of the hot and humid air; the other way is to allow the cooling medium to absorb the heat transferred from the hot and humid air to the outer wall of the cooling part to cool the hot and humid air, thereby accelerating the cooling speed and improving the cooling effect.

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

[0006] The present invention provides a heat exchanger for a dehumidification device, comprising a heat exchanger body arranged in a dehumidification device body, wherein the heat exchanger body is provided with a cooling portion; the cooling portion is provided with a cooling channel for accommodating a cooling medium; wherein,

[0007] The cooling channel is provided with a plurality of holes, which are connected to the cavity of the device body; when the cooling medium flows in the cooling channel, part of the cooling medium flows from the plurality of holes into the cavity;

[0008] The hot and humid air in the cavity contacts the outer wall of the cooling portion and / or contacts the cooling medium in the cavity to be cooled and dehumidified.

[0009] Preferably, the heat exchange element body further includes a plurality of air channels for accommodating hot and humid air.

[0010] Preferably, the cooling portion is located above the hot and humid air.

[0011] Preferably, a plurality of the holes are arranged on the bottom wall of the cooling channel.

[0012] Preferably, the hole corresponds to the position of the air channel.

[0013] Preferably, the apertures of the plurality of holes gradually decrease along the flow direction of the cooling medium.

[0014] Preferably, the cooling part includes a cavity and several partitions; the several partitions are arranged in sequence in the cavity; two adjacent partitions are staggeredly connected to the two opposite inner walls of the cavity, so as to form a cooling channel for the cooling medium to pass through together with the inner contour of the cavity.

[0015] Preferably, the plurality of partitions are arranged obliquely or perpendicularly to the contour of one side of the cavity.

[0016] Preferably, several partitions are arranged in parallel.

[0017] Preferably, the partitions are arranged at equal intervals along the flow direction of the hot and humid air.

[0018] Preferably, the ends of two adjacent partitions are staggered along a direction perpendicular to the partitions.

[0019] Preferably, the cooling portion is provided with a cooling medium outlet; the cooling medium outlet is communicated with the cooling channel and the cavity respectively.

[0020] Preferably, a plurality of the holes are distributed on a path leading to the cooling medium outlet.

[0021] A second object of the present invention is to provide a dehumidification device, comprising a device body disposed in a clothes dryer body for cooling and dehumidifying, the device body comprising:

[0022] a housing having a cavity;

[0023] The heat exchanger body of the heat exchanger for the moisture removal device as described above is arranged in the cavity;

[0024] The hot and humid air generated by the drying drum of the dryer body enters the cavity, contacts the outer wall of the cooling portion and / or contacts the cooling medium in the cavity, so that the cooling medium absorbs the heat of the hot and humid air. The hot and humid air is cooled and condensed to be dehumidified. The dehumidified air is discharged from the air outlet of the device body to the outside of the dryer body.

[0025] A third object of the present invention is to provide a clothes dryer, comprising a clothes dryer body for performing drying, wherein the clothes dryer body comprises a device body of the moisture removal device as described above.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention provides a heat exchanger for a dehumidification device, which absorbs the heat of humid hot air through a cooling part containing a cooling medium, so as to cool and dehumidify the humid hot air. The cooling channel of the cooling part is provided with a plurality of holes, so that the cooling part absorbs the humid hot air in two ways. One way is to allow the cooling medium flowing into the cavity from the plurality of holes to directly contact the humid hot air to absorb the heat of the humid hot air; the other way is to allow the cooling medium to absorb the heat transferred from the humid hot air to the outer wall of the cooling part to cool the humid hot air, so as to accelerate the cooling speed and improve the cooling effect. In a preferred embodiment, since the temperature of the cooling medium in the cooling channel gradually increases during the flow process, the aperture of the plurality of holes is gradually reduced along the flow direction of the cooling medium in the cooling channel to reduce the influence of the temperature difference of the cooling medium itself flowing out of the holes at different parts of the cooling channel on the cooling effect of the humid hot air in the cavity.

[0028] In a preferred embodiment, the cooling part of the device body is arranged in the cavity of the cooling part through a number of partitions. The number of partitions and the contour of the cavity together form a cooling channel, which increases the space of the cooling channel for accommodating the cooling medium, thereby increasing the contact area between the cooling medium and the cooling channel, improving the heat exchange effect with the hot and humid air, and controlling the space occupied by the cooling channel in the heat exchanger body, which is conducive to the miniaturized design of the cooling part.

[0029] In a preferred embodiment, the cooling unit is provided with a cooling medium outlet, which is connected to the cooling channel and the cavity, respectively. After absorbing heat in the cooling channel, the cooling medium is discharged from the cooling medium outlet into the cavity and then discharged together with condensed water from the drain outlet. This reduces the number of pipe openings provided in the housing and simplifies the piping layout when the device is installed in the dryer. Furthermore, a stopper is provided on the back of the cooling medium outlet to prevent the cooling medium from coming into contact with the hot and humid air during its flow from the cooling medium outlet. This reduces the contact area between the cooling medium, which has risen in temperature due to absorbing heat from the hot and humid air, and the hot and humid air, thereby preventing adverse cooling effects on the hot and humid air.

[0030] The present invention provides a dehumidification device, in which the device body cools the hot and humid air generated by the dryer, lowering the temperature of the hot and humid air while condensing the moisture in the hot and humid air into condensed water and removing it. After cooling and dehumidification, the air is discharged into the external environment of the dryer body, avoiding directly discharging the hot and humid air with high temperature and humidity generated by the dryer body into the external environment of the dryer body, which would increase the temperature and humidity of the environment and avoid causing environmental pollution. The hot and humid air generated by the dryer is cooled and dehumidified and then discharged out of the dryer body. The dehumidified air does not need to be recycled internally, thereby speeding up the drying process. Furthermore, the device body can cooperate with the condenser to cool and dehumidify the hot and humid air generated by the dryer body.

[0031] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the description, the following preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0046] Example 1

[0047] The present invention provides a heat exchange element for a moisture removal device, such as Figures 1 to 4 、 Figure 6 、 Figure 7 As shown, it includes a heat exchanger body 20 disposed in a device body 1 for dehumidification, and the heat exchanger body 20 is provided with a cooling portion 21; the cooling portion 21 is provided with a cooling channel 212 for accommodating a cooling medium; wherein,

[0048] The cooling channel 212 is provided with a plurality of holes 2121, which are in communication with the cavity 11 of the device body 1. As the cooling medium flows through the cooling channel 212, part of the cooling medium flows through the holes 2121 into the cavity 11. Specifically, as part of the cooling medium flows out of the holes 2121, it contacts the hot and humid air in the cavity 11. When the cooling medium flows to and accumulates on the inner wall of the cavity 11, it also contacts part of the hot and humid air in the cavity 11, thereby exchanging heat with the hot and humid air in the cavity 11.

[0049] The hot and humid air in cavity 11 contacts the outer wall of cooling portion 21 and / or the cooling medium in cavity 11, thereby being cooled and dehumidified. The hot and humid air generated by the dryer drum enters cavity 11, contacts the outer wall of cooling portion 21 and / or the cooling medium in cavity 11, causing the cooling medium to absorb heat from the hot and humid air. The hot and humid air is then cooled and condensed, thereby dehumidifying the air. The dehumidified air is then discharged from the dryer body through air outlet 13 of the device body 1 and out of the dryer body.

[0050] In one embodiment, if Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 As shown, the cooling channel 212 is curved to extend the length of the cooling channel 212 and reasonably control the space occupied by the cooling channel 212 in the cooling portion 21 .

[0051] In one embodiment, if Figure 2 、 Figure 4 As shown, the heat exchanger body 20 also includes several air channels 22 for accommodating hot and humid air. The hot and humid air generated by the clothes dryer enters the cavity 11 through the air inlet 12 and then flows into the air channels 22, thereby extending the time it takes for the hot and humid air to pass through the cavity 11. The air channels 22 are used to guide the flow of the hot and humid air, facilitating contact between the hot and humid air entering the air channels 22 and the cooling portion 21 for cooling. Furthermore, the air channels 22 are formed by several fins 23 or ejector pins. The fins 23 have a certain degree of thermal conductivity, which helps dissipate heat from the hot and humid air in the air channels 22. When the cooling portion 21 is located above or to the side of the air channels 22, the air channels 22 formed by the fins 23 or ejector pins are open at the bottom. This facilitates the removal of condensed water formed by the hot and humid air in the air channels 22 during the cooling process. The condensed water falls from the lower opening of the air channels 22 onto the inner wall of the housing 10 and is then discharged from the device body 1 through the corresponding drain port 15 on the housing 10.

[0052] In one embodiment, if Figure 5As shown, the space occupied by the cooling portion 21 in the cavity 11 is one-third to one-half of the space occupied by the air channel 22, so as to increase the height of the air channel 22 and increase the amount of humid hot air accommodated by the air channel 22. The humid hot air can be dispersed in the air channel 22 to prevent the air channel 22 from being too small, which causes the humid hot air to gather in the air channel 22, which is not conducive to the transfer of heat from the humid hot air.

[0053] In one embodiment, if Figure 2 、 Figure 5 As shown, the cooling unit 21 is located above the hot and humid air. Condensate formed during the cooling process falls under its own gravity and does not contact the outer walls of the cooling unit 21. This prevents condensate from accumulating on the outer walls of the cooling unit 21 and affecting its ability to absorb heat from the hot and humid air. Furthermore, the heat exchanger body 20 includes an air channel 22 for accommodating the hot and humid air, and the cooling unit 21 is located above the air channel 22.

[0054] In one embodiment, if Figures 2 to 4 As shown, a plurality of holes 2121 are provided on the bottom wall of the cooling channel 212. When the cooling medium flows out of the holes 2121, it falls under its own gravity, thereby reducing the cooling medium from adhering to the outer wall of the cooling portion 21 during the downward flow, so as to avoid affecting the heat exchange between the outer wall of the cooling portion 21 and the hot and humid air.

[0055] In one embodiment, if Figure 4 As shown, the position of hole 2121 corresponds to that of air passage 22 to prevent hole 2121 from aligning with the sidewall of air passage 22 and thus affecting the flow of cooling medium out of hole 2121. Furthermore, by limiting the size of hole 2121, the flow rate of cooling medium out of hole 2121 is limited to prevent the cooling medium from flowing out of hole 2121 too quickly and falling rapidly onto the bottom wall of cavity 11. This reduces the contact time between the cooling medium flowing out of hole 2121 and the moist and hot air within cavity 11, reducing the utilization rate of the cooling medium and causing cooling medium waste. Furthermore, the diameter of hole 2121 is controlled to prevent the cooling medium from flowing out of hole 2121 too slowly, which would result in poor cooling effect through direct contact between the cooling medium and the moist and hot air. It should be understood that the shape of hole 2121 includes, but is not limited to, circular, square, and bar-shaped. "Aperture" herein refers to the cross-sectional area equivalent to the area of ​​hole 2121.

[0056] In one embodiment, if Figures 2 to 4As shown, the cooling section 21 includes a cavity and several baffles 211. The baffles 211 are arranged sequentially within the cavity, with adjacent baffles 211 interlaced and connected to opposing inner walls of the cavity. The baffles 211 and the cavity's internal contours together form cooling channels 212 for the passage of cooling medium. This replaces the traditional solution of using curved pipe structures as cooling channels, reducing the space occupied by the spacing between adjacent pipe sections caused by the traditional curved pipe structure. This increases the size of the cooling channels 212 within the same cavity space, increasing the amount of cooling medium accommodated by the cooling section 21 and accelerating heat exchange.

[0057] In one embodiment, if Figure 6 As shown, several partitions 211 are arranged at an angle, which increases the contact area between the inclined partitions 211 and the cooling medium contained in the cooling channel 212, improves the heat exchange efficiency between the partitions 211 and the cooling medium, and accelerates the cooling medium's absorption of heat from the hot and humid air. Furthermore, by limiting the angle between the partitions 211 and the inner sidewall corresponding to the position of the cavity, the length of the partitions 211 that can be accommodated in the cavity is guaranteed. The partitions 211 are heat conducting sheets to accelerate the speed at which the cooling unit 21 absorbs heat from the hot and humid air. In another embodiment, as Figure 1 As described above, the plurality of partitions 211 are all arranged perpendicular to the contour of one side of the cavity, so as to increase the number of partitions 211 that can be accommodated in the cavity.

[0058] In one embodiment, if Figures 2 to 4 、 Figure 6 、 Figure 7 As shown, several partitions 211 are arranged in parallel, and the cross-sectional profiles of various parts of the channels formed by two adjacent partitions 211 for accommodating the cooling medium in the same direction are consistent in size, so that the cooling medium flows smoothly in the channels formed by the two adjacent partitions 211, and is not prone to turbulence caused by changes in the size of the cooling channel, which causes noise.

[0059] Furthermore, the baffles 211 are arranged at equal intervals along the direction of the hot and humid air flow. That is, the cross-sectional profiles of the channels formed between any two adjacent baffles 211 are of uniform size in the same direction. This allows the cooling medium to maintain a consistent or similar flow rate when it passes through a bend and enters the channel formed by the next two adjacent baffles 211 within the cooling channel 212, thereby reducing noise caused by unstable cooling medium flow.

[0060] Furthermore, the partition 211 is a heat conducting sheet to improve the cooling effect of the cooling section 21. Specifically, after the hot and humid 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 of the heat is first transferred to the partition 211, and then transferred to the cooling medium through the partition 211, thereby accelerating the dissipation of the heat of the hot and humid air absorbed by the cooling section 21, and further accelerating the absorption of the heat of the hot and humid air in the cavity 11 by the outer wall of the cooling section 21. In addition, the partition 211 is tilted in the cavity of the cooling section 21, which increases the length of the partition 211 to a certain extent, thereby increasing the contact area between the partition 211 and the cooling medium, improving the heat exchange efficiency between the cooling medium and the partition 211, and accelerating the absorption of the heat of the hot and humid air by the cooling medium.

[0061] In one embodiment, two adjacent baffles 211 are staggered and connected to opposing inner walls of the cavity. Furthermore, the cooling medium inlet (corresponding to the cooling medium inlet 14 of the housing 10) and the cooling medium outlet of the cooling channel 212 are located outside the two outermost baffles 211. This fully utilizes the cavity space, allowing the space to accommodate the cooling medium and the baffles 211, thereby increasing the amount of cooling medium that can be accommodated in the cavity.

[0062] In one embodiment, the ends of two adjacent baffles 211 intersect perpendicularly to the baffles 211 to form a curved cooling channel 212. This creates a curved flow path, ensuring stable cooling medium flow and ensuring the cooling medium's residence time within the cooling channel 212. Cooling medium entering the cavity first flows into a first channel connected to the cooling medium inlet end of the cooling channel 212, then into a second channel adjacent to the first channel, then into a third channel adjacent to the second channel, and so on. The baffles 211 are strategically arranged to ensure stable cooling medium flow. The adjacent channels formed by the baffles 211 form a "U" shape, further enhancing the stability of the cooling medium flow.

[0063] Furthermore, the vertical distance between two adjacent partitions 211 is equal to the distance between the end of the partition 211 and the inner wall of the shell 10, so as to reduce the impact of the cooling medium on the flow velocity of the cooling medium when it flows to the bend in the cooling channel 212, so as to avoid turbulence.

[0064] In one embodiment, if Figure 2 、 Figure 5As shown, the plane where the partition 211 is located intersects the plane where the air channel 22 is located. Specifically, there are a plurality of air channels 22, and the plane where the partition 211 is located intersects the plane where the air channel 22 is located. This 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 hot and humid air in each air channel 22.

[0065] In one embodiment, if Figures 2 to 7 As shown, the cooling portion 21 is provided with a cooling medium outlet 213; the cooling medium outlet 213 is respectively connected to the cooling channel 212 and the cavity 11. The cooling medium is introduced into the cooling channel 212 through the cooling medium inlet 14 of the housing 10. Part of the cooling medium flows out of the plurality of holes 2121 during the process of flowing in the cooling channel 212, directly contacting the hot and humid air in the cavity 11 to exchange heat. Eventually, this part of the cooling medium falls on the bottom wall of the cavity 11 and is discharged from the drain port 15 of the housing 10 together with the condensed water generated during the cooling of the hot and humid air. Part of the cooling medium flows into the cavity 11 through the cooling medium outlet 213, exchanges heat with the hot and humid air in the cavity 11 that contacts the cooling portion 21, and is discharged from the cooling medium outlet 213 into the cavity 11. It is then discharged from the drain port 15 of the housing 10 together with the condensed water generated during the cooling of the hot and humid air. The cooling medium outlet 213 is disposed on the cooling portion 21 rather than on the housing 10 , so as to reduce the number of pipes connected to the housing 10 and simplify the pipe layout structure when the device body 1 is installed in the dryer body.

[0066] Specifically, in one embodiment, the outer wall of the cooling channel 212 that contacts the hot and humid air in the cavity 11 is a heat conducting fin structure to ensure heat exchange between the cooling medium and the hot and humid air in the cooling channel 212. In another embodiment, the heat exchanger body 20 is a heat conducting structure to enhance heat exchange between the hot and humid air in the cavity 11.

[0067] In one embodiment, if Figure 4 、 Figure 5As shown, a stopper 2131 is provided on the back side of the cooling medium outlet 213 to prevent the cooling medium in the cooling channel 212 from coming into contact with the hot and humid air during its flow out of the cooling medium outlet 213. Since the temperature of the cooling medium increases after absorbing heat from the hot and humid air, the stopper 2131 is provided to block the contact area between the cooling medium discharged from the cooling medium outlet 213 into the cavity 11 and the hot and humid air, thereby preventing the cooling medium, which has absorbed heat, from adversely affecting the cooling of the hot and humid air. In one embodiment, the heat exchanger body 20 includes a plurality of air channels 22 for accommodating hot and humid air. The stopper 2131 is provided to block the cooling medium flowing out of the cooling medium outlet 213 from entering the air channels 22, thereby preventing the cooling medium, which has absorbed heat from the hot and humid air, from flowing into the air channels 22 upon exiting the cooling channel 212. This reduces the contact area between the cooling medium, which has increased in temperature due to absorbing heat from the hot and humid air, and the hot and humid air, thereby preventing the cooling medium, which has absorbed heat from the air, from adversely affecting the cooling of the hot and humid air. Furthermore, the stop portion 2131 is bent and together with the inner walls on both sides of the cavity 11 form a wall structure that surrounds the cooling medium flowing out of the cooling medium outlet 213. The wall structure can be completely or partially closed on all sides, guiding the cooling medium to flow toward the drain port 15 while separating the air channel 22 from the cooling medium flowing out of the cooling medium outlet 213.

[0068] Furthermore, the height of the stopper 2131 is greater than the height of the side wall of the air channel 22 , so as to further ensure that the cooling medium flowing out of the cooling medium outlet 213 does not enter the air channel 22 .

[0069] Furthermore, the stopper 2131 is a heat conducting plate, and the cooling medium discharged from the cooling medium outlet 213 remains along the inner wall of the stopper 2131, and the hot and humid air in the cavity 11 contacts the outer wall of the stopper 2131. Through the heat transfer function of the stopper 2131 which is a heat conducting plate structure, the cooling medium discharged from the cooling medium inlet 14 absorbs part of the heat of the hot and humid air contacting the outer wall of the stopper 2131, so as to make full use of the cooling medium and speed up the cooling speed of the hot and humid air in the cavity 11.

[0070] In one embodiment, if Figure 3 、 Figure 6 、 Figure 7As shown, a plurality of holes 2121 are distributed along the path leading to the cooling medium outlet 213. After the cooling medium enters the cooling channel 212 from the cooling medium inlet 14 of the housing 10, as it flows toward the cooling medium outlet 213, the cooling medium absorbs more and more heat from the hot and humid air in the cavity 11, causing the cooling medium temperature to rise gradually until the cooling medium reaches the highest temperature when it reaches the cooling medium outlet 213. The plurality of holes 2121 are distributed along the path leading to the cooling medium outlet 213, i.e., no holes 2121 are provided between the cooling medium outlet 213 and the end of the cooling channel 212. When the cooling medium flows to the position between the cooling medium outlet 213 and the end of the cooling channel 212, the cooling medium is blocked by the contour of the end of the cooling channel 212 and then flows back to the cooling medium outlet 213. This prevents the cooling medium from flowing into the cavity 11 at the position between the cooling medium outlet 213 and the end of the cooling channel 212. At this time, the cooling medium temperature is high, which is not conducive to cooling the hot and humid air in the cavity 11. Furthermore, the plurality of holes 2121 are evenly distributed on the path leading to the cooling medium outlet 213 , so that the cooling medium in the cooling channel 212 is evenly sprinkled to the hot and humid air in the cavity 11 through the plurality of holes 2121 , thereby improving the heat exchange effect.

[0071] In one embodiment, if Figure 7 As shown, the inner dimensions of the plurality of holes 2121 gradually decrease along the flow direction of the cooling medium in the cooling channel 212. The temperature of the cooling medium in the cooling channel 212 gradually increases during flow, reaching its highest temperature when it flows to the cooling medium outlet 213. By limiting the inner dimensions of the plurality of holes 2121, the amount of high-temperature cooling medium in the cooling channel 212 that flows from the holes 2121 into the cavity 11 is reduced, thereby reducing the impact of the temperature difference of the cooling medium flowing from the holes 2121 into the cavity 11 on the cooling effect of the hot and humid air in the cavity 11.

[0072] Further, if Figure 2 、 Figure 5 As shown, the height of the partition 211 is smaller than the height of the peripheral contour of the cavity, so as to facilitate the processing of the cooling portion 21 and reduce the requirements for the processing accuracy of the partition 211, so as to avoid the height of the partition 211 being higher than the height of the peripheral contour of the cavity during processing, thereby affecting the outer contour of the opening of the cooling portion 21 against the inner wall of the shell 10, and thus failing to close the cooling channel 212. When there is a lot of cooling medium in the cooling channel 212 or the flow is fast, 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 portion 21 and the inner wall of the shell 10.

[0073] In one embodiment, if Figure 2 、 Figure 5As shown, the cooling unit 21 is provided with a cooling medium outlet 213 disposed on the bottom wall of the cavity. Under its own gravity, the cooling medium flows out of the cooling medium outlet 213 and can directly fall to the bottom wall of the cavity 11. This reduces the probability of the cooling medium contacting the surrounding contour of the cavity 11, preventing the cooling medium from accumulating on the surrounding contour surface of the cavity 11, which would increase the humidity in the cavity 11 and hinder the dehumidification of the hot and humid air.

[0074] In one embodiment, if Figure 2 、 Figure 3 As shown, a gap is provided between the cooling medium outlet 213 and the end of the cooling channel 212. When the cooling medium flows from the cooling channel 212 toward the cooling medium outlet 213, some of the cooling medium flows from the cooling medium outlet 213 into the cavity 11 and then to the drain port 15, while some of the cooling medium continues to flow within the cooling channel 212 toward the end thereof, thereby achieving a certain flow diversion effect. This avoids the situation in which the cooling medium flowing to the end of the cooling channel 212 cannot be discharged from the cooling medium outlet 213 in a timely manner when the cooling medium outlet 213 is positioned at the end of the cooling channel 212, thereby forming turbulent flow and causing noise.

[0075] In one embodiment, if Figure 2 As shown, cooling portion 21 has an opening facing curved cooling channel 212. Because device body 1 is used in a clothes dryer, to save costs and simplify the internal structure of the dryer, the cooling medium is cooling water. Cooling water is inexpensive and easily accessible. Cooling water can be promptly supplied to device body 1 through the waterway within the dryer, eliminating the need to replace the cooling medium and providing convenient operation. Cooling water absorbs heat and rises in temperature. Since the water used in clothes dryers typically contains scale-forming ions such as calcium and magnesium ions, scale may form as the cooling water temperature rises. The provision of an opening in the cooling portion allows for monitoring scale formation and timely removal.

[0076] Example 2

[0077] The present invention provides a heat exchange element for a moisture removal device, such as Figure 2 、 Figure 5 As shown, the device body 1 is provided in the dryer body, and the device body 1 includes:

[0078] The housing 10 is provided with a cavity 11 for accommodating the heat exchanger body 20. The cavity 11 is used to accommodate the heat exchanger body 20 and form a temporary storage space for hot and humid air. After the hot and humid air enters the cavity 11, the contour of the cavity 11 reduces the flow rate of the hot and humid air, causing the hot and humid air to temporarily gather in the cavity 11 and contact the heat exchanger body 20 in the cavity 11.

[0079] The heat exchanger body 20 of the heat exchanger for the dehumidification device as described above is disposed in the cavity 11;

[0080] The hot and humid air generated by the drying drum of the clothes dryer body enters the cavity 11, contacts the outer wall of the cooling portion 21 and / or contacts the cooling medium in the cavity 11, so that the cooling medium absorbs the heat of the hot and humid air. The hot and humid air is cooled and condensed to be dehumidified. The dehumidified air is discharged from the air outlet 13 of the device body 1 to the outside of the clothes dryer body. Specifically, Figure 2 、 Figure 5 、 Figure 8 As shown, the housing 10 is provided with an air inlet 12 and an air outlet 13. The air inlet 12 is communicated with the clothes drying drum, and the air outlet 13 is communicated with the external environment of the clothes dryer body. After the dryer body starts the drying program, the heater of the dryer body heats the air entering the dryer drum. The heated air causes the moisture contained in the clothes in the dryer drum to evaporate by heat to form an airflow containing water molecules. Under the guidance of the fan of the dryer body, the airflow containing water molecules is mixed with the hot air in the dryer drum, forming humid hot air with relatively high temperature and humidity. The humid hot air generated by the dryer drum enters the cavity 11 through the air inlet 12, contacts the cooling part 21 of the heat exchanger body 20 located in the cavity 11 and the cooling medium flowing out of the cavity 11 from the plurality of holes 2121 to be cooled. During the cooling process, the humid hot air forms condensed water to dehumidify, and the air after cooling and dehumidification is discharged into the external environment of the dryer body, reducing the impact on the temperature and humidity of the environment in which the dryer body is located and avoiding environmental pollution. The humid hot air in the dryer drum is discharged in time to speed up the drying process of the dryer body. Furthermore, by limiting the heat absorption performance of the cooling unit 21, the temperature and humidity of the air discharged from the dryer body after being treated by the device body 1 can be controlled. For example, the temperature of the air discharged from the dryer body can be controlled to be slightly lower than room temperature, and the humidity can be controlled to a comfortable humidity standard. In hot seasons, the temperature of the environment surrounding 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 pass through.

[0081] In one embodiment, in order to save costs and simplify the internal structure of the dryer body, the cooling medium is cooling water. Cooling water is cheap and easy to obtain. Cooling water can be provided to the device body 1 in a timely manner through the water channel in the dryer body. There is no need to replace the cooling medium, and the operation is convenient.

[0082] In one embodiment, if Figure 2 、 Figure 5As shown, the cooling portion 21 of the heat exchanger body 20 is provided with a cooling medium outlet 213 corresponding to the position of the drain port 15 of the shell 10. The drain port 15 of the shell 10 is located on the bottom wall of the shell 10. The condensed water formed by the hot and humid air during the cooling process falls onto the bottom wall inside the shell 10 and is discharged from the drain port 15, which is conducive to the discharge of the condensed water, so as to prevent excessive accumulation of condensed water in the cavity 11, thereby affecting the humidity inside the cavity 11 and further affecting the cooling effect of the cooling portion 21. The cooling medium outlet 213 corresponds to the position of the drain port 15. After absorbing the heat of the hot and humid air, the cooling medium is discharged from the cooling medium outlet 213 and can reach the drain port 15 as soon as possible under its own gravity for discharge, so as to prevent the cooling medium from not being discharged in time and accumulating in the cavity 11, affecting the humidity of the cavity 11 and hindering the dehumidification of the hot and humid air.

[0083] In one embodiment, the cooling portion 21 of the heat exchanger body 20 is provided with a cooling medium outlet 213 located near the air inlet 12 of the housing 10. The hot and humid air generated by the clothes dryer enters the cavity 11 through the air inlet 12. At this time, the hot and humid air has a high humidity, i.e., the humidity and temperature of the air in the cavity 11 near the air inlet 12 are the highest. Since the cooling medium outlet 213 is located near the air inlet 12, the temperature and humidity of the hot and humid air at the air inlet 12 are not significantly affected by the cooling medium discharged from the cooling medium outlet 213. Furthermore, the cooling medium outlet 213 corresponds to the position of the drain outlet 15. When the condensed water formed during the cooling process of the cooling medium and the humid hot air flows toward the drain outlet 15, it affects the humidity in a certain space around the drain outlet 15 to a certain extent. The temperature and humidity of the humid hot air at the air inlet 12 are not greatly affected by the temperature and humidity of the certain space around the drain outlet 15. Even if the temperature and humidity of the humid hot air at the air inlet 12 are affected and increase, the humid hot air at the air inlet 12 exchanges heat with the cooling medium to cool down and dehumidify in the process of flowing toward the air outlet 13 of the shell 10, so as to ensure that the temperature and humidity of the air discharged from the air outlet 13 meet the specified requirements.

[0084] Furthermore, a stopper 2131 disposed on the back side of the cooling medium outlet 213 is offset from the air inlet 12 to prevent the hot and humid air entering through the air inlet 12 from contacting the cooling medium flowing out of the cooling medium outlet 213. Specifically, the air inlet 12 is disposed on a side of the housing 10 near the drain outlet 15, and the cooling medium outlet 213 corresponds to the drain outlet 15. As the hot and humid air entering through the air inlet 12 flows into the air passage 22 of the heat exchanger body 20, the offsetting of the stopper 2131 from the air inlet 12 reduces the contact area between the hot and humid air entering through the air inlet 12 and the cooling medium discharged from the cooling medium outlet 213, thereby reducing the effect of the cooling medium discharged from the cooling medium outlet 213 on the humidity of the hot and humid air entering through the air inlet 12. If a small amount of hot and humid air contacts the cooling medium, the amount of this hot and humid air is small, and thus, it can subsequently exchange heat with the cooling medium in the cooling unit 21 to dehumidify the air as it passes through the air passage 22.

[0085] In one embodiment, if Figure 5 As shown, the device body 1 is provided with a partition that divides the cavity 11 into two areas; the cooling portion 21 and the humid hot air are located on either side of the partition, so that the cooling portion 21 and the humid hot air entering the cavity 11 are located in two relatively independent spaces. This prevents the humid hot air from forming condensed water during the cooling process, which would cause the outer wall of the cooling portion 21 to come into contact with excessive moisture and hinder the cooling portion 21 from absorbing heat from the humid hot air. Furthermore, in one embodiment, the heat exchanger body 20 includes a plurality of air channels 22 for accommodating the humid hot air. The cooling portion 21 and the air channels 22 are located on either side of the partition, so that the cooling portion 21 and the air channels 22 are located in two relatively independent spaces. Specifically, the condensed water formed by the cooling and condensation of the hot and humid air in the air channel 22 will cause the humidity of the space in which the air channel 22 is located to a certain extent to increase, thereby separating the cooling part 21 from the air channel 22. The increase in the humidity of the air channel 22 will not affect the humidity of the environment in which the cooling part 21 is located, so as to prevent the increase in the humidity of the environment in which the cooling part 21 is located from causing the outer wall of the cooling part 21 to contact more water molecules. The cooling part 21 will absorb the heat of the water molecules that its outer wall contacts, thereby affecting the cooling effect of the cooling part 21.

[0086] Furthermore, the first wall 214 of the cooling portion 21 facing the hot and humid air is in contact with the contour of the cavity 11 to form a partition. Specifically, the first wall 214 of the cooling portion 21 facing the air channel 22 is in contact with the contour of the cavity 11 to form a partition, and there is no need to set up an additional partition to occupy the space in the cavity 11. Furthermore, the two sides of the first wall 214 are in contact with the cooling medium in the cooling channel 212 and the hot and humid air in the air channel 22, respectively. The first wall 214 is a heat conducting plate to increase the speed of transferring the heat of the hot and humid air to the cooling medium in the cooling channel 212, thereby 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 plurality of mounting holes 2141, so that the heat exchanger body 20 can be fixed in the cavity 11 by fasteners.

[0087] In one embodiment, if Figure 2 As shown, cooling portion 21 has an opening facing curved cooling channel 212. Because device body 1 is used in a clothes dryer, to save costs and simplify the internal structure of the dryer, the cooling medium is cooling water. Cooling water is inexpensive and easily accessible. Cooling water can be promptly supplied to device body 1 through the waterway within the dryer, eliminating the need to replace the cooling medium and providing convenient operation. Cooling water absorbs heat and rises in temperature. Since the water used in clothes dryers typically contains scale-forming ions such as calcium and magnesium ions, scale may form as the cooling water temperature rises. The provision of an opening in the cooling portion allows for monitoring scale formation and timely removal.

[0088] Further, if Figure 5 As shown, the outer contour of the opening of the cooling portion 21 of the heat exchanger body 20 abuts against the inner wall of the shell 10 to form a closed cooling channel 212, thereby preventing the cooling medium inside the cooling channel 212 from leaking. Furthermore, the cooling portion 21 is open to form the opening, and the opening contour is large, which facilitates observation and cleaning of scale in the cooling channel; and when the heat exchanger body 20 is installed, the open end of the cooling portion 21 abuts against the inner wall of the shell 10, and the cooling medium in the cooling channel 212 will 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 interior of the shell 10, in order to prevent the cooling medium in the cooling channel 212 from leaking from its opening, the cooling portion 21 is placed facing the opening.

[0089] In one embodiment, if Figure 2 、 Figure 5 、 Figure 8 As shown, the housing 10 includes a first housing 16 and a second housing 17. The first housing 16 and the second housing 17 are clamped together to form a cavity 11. The first housing 16 and the second housing 17 are detachably connected to facilitate the assembly and disassembly of the heat exchanger body 20.

[0090] Example 3

[0091] The present invention provides a clothes dryer, comprising a dryer body for performing drying. The dryer body includes a device body 1 having a heat exchange element for a dehumidification device as described above. The dryer body includes a housing and a drying drum; the drying drum and the device body 1 are both disposed within the housing. The air outlet 13 of the device body 1 is in one-way communication with the environment outside the housing, for discharging the cooled and dehumidified hot and humid air within a cavity 11 out of the housing. When the dryer body performs a drying cycle, the hot and humid air from the drying drum enters the cavity 11 through the air inlet 12. After absorbing heat and cooling in the cooling unit 21, the moisture in the hot and humid air is condensed and removed, and then discharged out of the housing through the air outlet 13. The cooling unit 21 cools the hot and humid air by direct contact of the cooling medium flowing out of the plurality of holes 2121 with the hot and humid air to cool it, and by absorbing heat transferred from the hot and humid air to the outer wall of the cooling unit 21 by the cooling medium within the cooling channel 212, thereby accelerating the cooling of the hot and humid air. After absorbing heat, the cooling medium in cooling channel 212 is discharged into cavity 11 through cooling medium outlet 213 and, along with the condensed water, is discharged through drain port 15 of housing 10, simplifying the piping layout when device body 1 is installed within the dryer. The hot and humid air generated by the dryer drum is cooled and dehumidified through device body 1 before being discharged into the external environment. This avoids direct discharge of the hot and humid air from the dryer drum outside the dryer, which would increase the humidity and temperature outside the dryer, affect the external environmental parameters of the dryer, and negatively impact the user experience and the preservation of furniture in the same environment.

[0092] 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 dry air heated by the heater into the drying drum to dry the clothes in the drying drum.

[0093] In one embodiment, the cooling medium is cooling water. The cooling medium inlet 14 of the device body 1 is connected to the water inlet valve in the dryer body to introduce cooling water. The drain outlet 15 of the device body 1 is connected to the drain pipe of the dryer body.

[0094] In one embodiment, the dryer body includes a condenser. A drain outlet 15 of the dryer body 1 communicates with the condenser, allowing cooling water discharged from the drain outlet 15 after absorbing heat and condensed water generated during the cooling of the moist hot air to be directed into the condenser as a cooling medium. Specifically, the condenser condenses the moist hot air entering the condenser from the dryer drum to form dry air, which is then supplied to the heater within the dryer body. The dry air, heated by the heater, is then directed into the dryer drum to continue drying the clothes, thereby dehumidifying the hot, moist air generated within the dryer drum and recycling the dry air. Specifically, the cooling water discharged from the cooling medium outlet 213 of the cooling channel 212, after absorbing heat from the moist hot air, falls onto the bottom wall of the housing 10, where it merges with the condensed water and is discharged through the drain outlet 15. The drain outlet 15 of the dryer body 1 communicates with the condenser, allowing the cooling water, which has absorbed heat from the moist hot air within the dryer body 1, and the condensed water to be directed into the condenser as the condenser's cooling medium. Furthermore, to save energy and speed up drying, an air inlet valve and temperature and humidity sensor are installed at the air inlet 12 of the dryer body 1. When the dryer body is drying, the condenser and water inlet valve are first opened, and cooling water is introduced into the cooling medium inlet 14. At this point, the hot and humid air from the dryer drum enters only the condenser. The water inlet valve of the dryer body introduces cooling water into the cooling portion 21 of the dryer body 1. At this point, the hot and humid air from the dryer drum is not introduced into the dryer body 1. The cooling water in the dryer body 1 is discharged from the drain port 15 into the condenser to cool and dehumidify the hot and humid air from the dryer drum that is introduced into the condenser. When the temperature of the air in 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, and part of the hot and humid air in the dryer enters the condenser, and part enters the device body 1. The hot and humid air generated in the dryer is processed simultaneously by the condenser and the device body 1, thereby speeding up the drying process. At this time, since the temperature of the hot and humid air in the dryer has dropped, the amount of heat absorbed by the cooling water after the hot and humid air enters the device body 1 is reduced, and the temperature of the cooling water after absorbing the heat of the hot and humid air increases, but the increase is not high, and the temperature difference with the hot and humid air generated in the dryer at this time is still large. Therefore, after the cooling water that absorbs the heat in the device body 1 is discharged from the drain port 15 to the condenser, it can still cool the hot and humid air in the condenser and ensure a certain cooling speed. Part of the hot and humid air generated by the dryer is passed into cavity 11 of the dryer body 1 for cooling and dehumidification, while part is passed into the condenser for condensation, dehumidification, and recovery of the dry air. This improves the processing speed of the high-temperature hot and humid air generated by the dryer. Furthermore, the cooling water provided by the dryer body's water inlet valve is reused, saving water. In one embodiment, the condenser also includes a medium inlet (not shown) connected to the dryer body's water inlet valve to allow the entry of cooling water, thereby improving the cooling rate of the condenser.

[0095] In another embodiment, the drain port 15 is connected to the drain pipe of the dryer body to drain the liquid discharged from the drain port 15 out of the dryer body. In another embodiment, a collection box connected to the drain port 15 is provided in the dryer body to collect the liquid discharged from the drain port 15.

[0096] Compared to existing technologies, the present invention provides a heat exchanger for a dehumidification device. This heat exchanger absorbs heat from hot and humid air through a cooling unit containing a cooling medium, thereby cooling and dehumidifying the hot and humid air. The cooling channel of the cooling unit is provided with a plurality of holes. The cooling unit absorbs the hot and humid air in two ways: one is to allow the cooling medium flowing into the cavity through the holes to directly contact the hot and humid air, thereby absorbing the heat from the hot and humid air; the other is to allow the cooling medium to absorb heat transferred from the hot and humid air to the outer wall of the cooling unit, thereby cooling the hot and humid air and accelerating the cooling process.

[0097] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and the above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
