Generally, the temperature of the air discharged is higher than that of the air entering after the wet air entering from the air inlet of the dehumidifier is condensed by the cooler and heated by the heater. In some designs, due to limited space occupancy, it is necessary to reduce the volume of the dehumidifier. Since the heater and the cooler are important components of the dehumidifier and affect the volume of the dehumidifier, reducing the volume of the heater and the cooler easily leads to a reduction in the heat exchange performance of the dehumidifier. Therefore, how to balance reducing the volume of the dehumidifier and meeting the heat exchange performance requirements has become a technical problem that concerns those skilled in the art.

[0031] As Figures 1 - 7 shown, the heat exchange assembly 100. According to the heat exchange assembly 100 of the embodiment of the present utility model, the heat exchange assembly 100 includes a first heat exchanger 10 and a second heat exchanger 20. The first heat exchanger 10 includes a first member 11 and a second member 21. The first member 11 has a first cavity 111. The first member 11 can be an integral hollow tube or a tube with an inner cavity formed by combining two or more components, which is not limited here. Similarly, the second member 21 is the same and will not be repeated here. The second member 21 has a second cavity 211. The first heat exchanger 10 further includes a first heat exchange tube 13. The first heat exchange tube 13 has a plurality of first channels 131. The plurality of channels are spaced apart in the width direction of the first tube. The first channels 131 extend along the length direction of the first heat exchange tube 13. The internal channels of the first heat exchange tube 13 are available for fluid flow. One end of the first heat exchange tube 13 is connected to the first member 11, and the other end of the first heat exchange tube 13 is connected to the second member 21, so that the first cavity 111 and the first channels 131 are communicated, and the first channels 131 are communicated with the second cavity 211, which is beneficial to the internal fluid flow of the first heat exchanger 10.

[0032] The second heat exchanger 20 includes a third member 12 and a fourth member 22. The third member 12 has a third chamber (not shown in the figure). The third member 12 can be an integral hollow tube or a tube with an inner cavity formed by combining two or more components, which is not limited here. Similarly, the fourth member 22 is the same and will not be repeated here. The fourth member 22 has a fourth chamber (not shown in the figure). The second heat exchanger 20 further includes a second heat exchange tube 23. The second heat exchange tube 23 has a plurality of second heat exchange channels 231. The plurality of second channels 231 are spaced apart in the width direction of the second heat exchange tube 23. The second channels 231 extend along the length direction of the second heat exchange tube 23. The third chamber is in communication with the second channels 231, and the second channels 231 are in communication with the fourth chamber, which is beneficial to the internal fluid flow of the second heat exchanger 20.

[0033] Since both the first heat exchange tube 13 and the second heat exchange tube 23 adopt a multi-channel structure, when the heat exchange assembly 100 is in operation, it is beneficial to increase the contact area between the internal fluid and the heat exchange tube, thereby increasing the heat exchange area of the heat exchange assembly 100, and further improving the heat exchange performance of the heat exchange assembly 100.

[0034] The heat exchange assembly 100 further includes a throttling member 30. The throttling member 30 can be any one of a capillary tube member, an electronic expansion valve assembly, a throttle tube assembly, etc. that can achieve a throttling effect. In the heat exchange assembly 100 of this embodiment, the throttling member 30 adopts a capillary tube member. The capillary tube member has a first interface and a second interface, and the first interface is in communication with the second interface.

[0035] In the embodiment of the present utility model, in order to improve the connection reliability between components, the heat exchange assembly further includes a first connecting pipe 16 and a second connecting pipe 26. The first connecting pipe 16 is a hollow structure, and the second connecting pipe 26 is a hollow structure. One end of the first connecting pipe 16 is connected to the first member 11, the other end of the first connecting pipe 16 is connected to one end of the capillary tube member, the other end of the capillary tube member is connected to one end of the second connecting pipe 26, and the other end of the second connecting pipe 26 is connected to the second member 21.

[0036] Since the diameter of the capillary tube is smaller than the diameter of the second connecting pipe 26, when the heat exchange assembly 100 is in the dehumidification working condition, when the fluid flows from the second connecting pipe 26 to the throttling member 30, the capillary tube member can throttle the fluid.

[0037] In some embodiments, the width of the first heat exchange tube 13 is W1, and the width of the second heat exchange tube 23 is W2, where 0.27 < W1 / W2 < 0.85. In the heat exchange assembly 100 of this embodiment, when the heat exchange assembly 100 is in the working state, the first heat exchange assembly 10 is used as an evaporator, and the second heat exchanger 20 is used as a condenser. Therefore, when the relationship between W1 and W2 is less than 0.27, the heat exchange capacity of the condenser is insufficient, affecting the heat exchange performance of the heat exchange assembly 100. When the relationship between W1 and W2 is greater than 0.85, the heat exchange capacity of the evaporator is excessive. Only when the relationship between W1 and W2 is between 0.27 and 0.85, the internal volume performance of the two matches appropriately, which can improve the heat exchange performance of the heat exchange assembly 100 and reduce costs.

[0038] In some embodiments, the structures of the first part 11 and the third part 12 of the first heat exchanger 10 are the same, and the structures of the second part 21 and the fourth part of the second heat exchanger 20 are the same. The first part 11 and the second part 21 are both of hollow structures, and the third part 12 and the fourth part 22 are both of hollow structures. The equivalent diameter of the first part 11 and the second part 21 is D1, and the equivalent diameter of the second part 21 and the fourth part 22 is D2. The heat exchange performance ratio is optimal and the heat exchange performance is the highest when the equivalent diameter ratio of the two heat exchange assemblies is between 0.3 < D1 / D2 < 0.9. Because the internal volume of the first heat exchanger 10 is related to the first part 11 and the third part 12, and the internal volume of the second heat exchanger 20 is related to the second part 21 and the fourth part 22. When D1 / D2 is less than 0.3, the first heat exchanger 10 has insufficient heat exchange performance. When D1 / D2 is greater than 0.9, the second heat exchanger 20 has excessive heat exchange performance, both of which will affect the overall heat exchange performance of the heat exchange assembly.

[0039] In some embodiments, the internal volume of the first heat exchanger 10 depends on the internal volumes of multiple components, including the internal volume of the first heat exchange tubes 13, and the internal volumes of the first part 11 and the third part 12. The internal volume of the second heat exchanger 20 depends on the internal volumes of multiple components, including the internal volume of the second heat exchange tubes 23, and the internal volumes of the second part 21 and the third part 12. It can be understood that the first heat exchange tube 13 assembly may include one or more than two first heat exchange tubes 13. The second heat exchanger 20 may also include one or more than two second heat exchange tubes 23. If there is only one heat exchange tube, the appearance of the heat exchange tube may also be a bent tube with a straight section 231 and a bent section 232 such as an S-shaped structure. The internal volume of the first heat exchanger 10 is V1, and the internal volume of the second heat exchanger 20 is V2. When the ratio of the internal volume V1 of the first heat exchanger 10 to the internal volume V2 of the second heat exchanger 20, when the ratio of the internal volumes of the first heat exchanger 10 and the second heat exchanger 20 is less than 0.75, when the ratio of the first heat exchanger 10 and the second heat exchanger 20 is less than 0.75, there is a situation where the heat exchange performance of the first heat exchanger 10 is insufficient. If the ratio of the first heat exchanger 10 and the second heat exchanger 20 is greater than 1, there is a situation where the heat exchange performance of the second heat exchanger 20 is excessive. Therefore, when the relationship between the internal volume V1 of the first heat exchanger 10 and the internal volume V2 of the second heat exchanger 20 is 0.75 < V1 / V2 < 1, it is beneficial to improve the heat exchange performance of the heat exchange assembly 100 and beneficial to reduce costs.

[0040] In some embodiments, as Figure 1 and Figure 2 shown in the heat exchange assembly 100, the first heat exchanger 10 includes first fins 14. The first fins 14 are aluminum sheets. Mounting holes (not shown in the figure) may be provided on the first fins 14. As Figures 1 - 2 shown in the heat exchange assembly, the first heat exchanger 10 includes a plurality of first heat exchange tubes 13 and a plurality of first fins 14. The plurality of first heat exchange tubes 13 are spaced apart in the thickness direction of the first heat exchange tubes 13. The first heat exchange tubes 13 penetrate through the mounting holes on the first fins 14 to facilitate the fixed connection between the two. One first heat exchange tube 13 penetrates through a plurality of first fins 14. The plurality of first fins 14 are arranged at a preset distance interval in the length direction of the first heat exchange tubes 13. The first heat exchange tubes 13 and the plurality of first fins 14 are connected by welding. One end of the first heat exchange tube 13 is connected to the first part 11, and the other end of the first heat exchange tube 13 is connected to the third part 12. The connection includes direct connection and indirect connection, which is not limited herein.

[0041] In some embodiments, as Figure 7 and Figure 8 shown in the heat exchange assembly, mounting grooves 141 may also be provided on the first fins 14. The mounting grooves 141 have openings. The first fins 14 shown in this embodiment and Figure 1 Figure 2 shown first fins 14 are different.Figure 7 and Figure 8 As shown in Figure 8 , for the first heat exchanger 10, the first heat exchange tubes 13 are horizontally inserted into the installation grooves 141 of the first fins 14 to achieve the fixed connection between the first heat exchange tubes 13 and the first fins 14. Both the first fins 14 and the first heat exchange tubes 13 are made of aluminum material, so they are fixedly connected by welding. The first fins 14 are connected to the heat exchange tubes in the way of horizontally inserted fins, which is beneficial to improving the heat exchange performance of the first heat exchanger 10.

[0042] When the heat exchange assembly 100 is in the working state, on the windward side of the first heat exchanger 10, the temperatures of the partial outer surfaces of the first heat exchange tubes 13 are the same as those of the first fins 14, reducing the temperature difference between the first fins 14 and the first heat exchange tubes 13. Therefore, it is beneficial to improve the heat exchange performance of the first heat exchanger 10, and thus beneficial to improving the heat exchange performance of the heat exchange assembly.

[0043] In some embodiments, as Figures 1 - 2 , Figures 7 - 8 shown, since multiple components of the heat exchange assembly 100 are connected by welding, when the heat exchange assembly 100 is in the high-temperature processing state and the solder becomes liquid, in order to reduce the corrosion between the first fins 14 and the first component 11, and reduce the corrosion between the first fins 14 and the third component 12, therefore, a fifth component 15 is provided between the first fins 14 and the first component 11, and a fifth component 15 is provided between the first fins 14 and the third component 12. Therefore, the corrosiveness between the first fins 14 and the first component 11, and between the first fins 14 and the second component 21 can be reduced. Thus, the reliability of the heat exchange assembly 100 is improved, and the service life of the heat exchange assembly 100 is extended.

[0044] In some embodiments, as Figure 3 and Figure 4 shown, the width of the first fins 14 is W, and the outer perimeter of the first heat exchange tubes 13 is L, where 0.5 < W / L < 1. That is to say, when the ratio of the width W of the first fins 14 to the outer perimeter L of the first heat exchange tubes 13 is between 0.5 and 1, it is beneficial to reduce the temperature difference between the first fins 14 and the first heat exchange tubes 13, and beneficial to improving the heat exchange performance of the heat exchange assembly 100.

[0045] Furthermore, as Figure 3 and Figure 4In the illustrated embodiment of the heat exchange component, the height of the first fin 14 is H, and the cross-section of the first heat exchange tube 13 is S. Among them, when 0.05 < S / (W*H) < 0.3, that is to say, when the first fin 14 and the first heat exchange tube 13 satisfy 0.05 < S / (W*H) < 0.3, the proportion of the number of heat exchange tubes per unit area of the first heat exchanger 10 can be increased, the temperature difference between the first fin 14 and the first heat exchange tube 13 can be reduced, and the heat exchange performance of the heat exchange component 100 can be improved.

[0046] In some embodiments, such as Figure 3 and Figure 5 shown, the second heat exchanger 20 further includes a first plate 25. Generally, the second heat exchanger 20 includes a first plate 25. The first plate 25 has a third channel 253 that extends in the opposite direction of the length of the first plate 25. The first plate 25 is located on the outermost side in the height direction (X direction) of the heat exchange component. The second heat exchanger 20 further includes a second fin 24. There is a second fin 24 between the first plate 25 and the second heat exchange tube 23. The first plate 25 is fixedly connected to the second fin 24. The first plate 25 further includes a recess 251, and the recess 251 can block the third channel 253.

[0047] In some embodiments, since the first plate 25 has a third channel 253, when the heat exchange component 100 is used while being exposed to humid air, water vapor and dust in the air are likely to accumulate inside the first plate 25, causing corrosion of the first plate 25. Therefore, by flattening the ends of the first plate 25, recesses 251 can be formed at both ends of the first plate 25 respectively. The recesses 251 can block water vapor and dust in the air from entering the third channel 253, thereby improving the reliability of the first plate 25 and thus improving the reliability of the heat exchange component 100.

[0048] In some embodiments, such as Figure 2 、 Figure 6 and Figure 10 shown heat exchange component 100, specifically, as Figure 10 and Figure 11 shown, the first plate 25 further includes two flanges 252. One flange 252 is located between the recess 251 and the first part 11, and the other flange 252 is located between the other recess 251 and the third part 12. The flange 252 has a free end that can abut against part of the second fin 24. The free end of the flange 252 abuts against the end or other positions of the second fin 24. The flange 252 can keep a preset distance between the end of the second fin 24 and the first part 11 or between the end of the second fin 24 and the third part 12, which is beneficial to reducing the erosion corrosion between the second fin 24 and the first part 11, and reducing the erosion corrosion between the second fin 24 and the second part 21, thereby being beneficial to improving the reliability of the heat exchange component 100.

[0049] It is understandable that the flanging 252 can be in a regular shape or an irregular shape. The free end of the flanging 252 can be a flat structure, a curved structure, or even have a bent portion. Regardless of any deformation, the purpose is to be able to resist the connection between the second fin 24 and the first piece 21, or to resist the connection between the second fin 24 and the fourth piece 22.

[0050] Furthermore, in the heat exchange component 100 embodiment shown in Figure 10 and Figure 11 , the flanging 252 of the first plate 25 is formed by stamping a part of the first plate 25. It is understandable that the flanging 252 can also be connected to the first plate 25 by various other processing methods such as gluing, snap - fitting, welding, etc., so as to block the connection between the end of the second fin 24 and the first piece 11 or block the connection between the second fin 24 and the fourth piece 22.

[0051] In some embodiments, in the heat exchange component shown in Figure 7 and Figure 8 , the second heat exchange tube 23 can include more than two bent sections 232 and more than two straight sections 231. In order to satisfy the internal circulation of the entire second heat exchanger 20, one end of one of the multiple straight sections 231 is connected to one end of the bent section 232, the other end of the bent section 232 is connected to one end of another straight section 231, and the other end of one of the straight sections 231 is connected to the fourth piece 22. It is understandable that one end of another straight section 231 among the multiple straight sections 231 is connected to one end of another bent section 232, and the other end of another straight section 231 among the multiple straight sections 231 is communicated with the second piece 21. Since the connection points between the second heat exchange tube 23 and the second piece 21, and between the second heat exchange tube 23 and the fourth piece 22 are reduced, the refrigerant filling amount of the second piece 21 and the fourth piece 22 is reduced. This is beneficial to improving the heat exchange efficiency of the heat exchange component 100 and is also beneficial to reducing costs.

[0052] On the other hand, the bent second heat exchange tube 23 is beneficial to increasing the flow path of the heat exchange tube and is beneficial to improving the heat exchange performance of the heat exchange component 100.

[0053] It is understandable that the second heat exchange tube 23 does not necessarily have to adopt an integrally formed bent structure. The bent section 232 can be a connecting pipe sleeve, and two second heat exchange tubes 23 are connected through the connecting pipe sleeve, thereby realizing the overall connection function of the heat exchange component 100.

[0054] The heat exchange component 100 further includes a throttling member 30. In some embodiments, in Figure 7 and Figure 8The heat exchange assembly 100 shown has a throttling member 30 which is a capillary member. The capillary member has a first interface and a second interface. To improve the connection reliability and sealing performance of the heat exchange assembly, the heat exchange assembly further includes a first connecting pipe 16 and a second connecting pipe 26. The connecting pipes are hollow members. The first connecting pipe 16 is connected to the first member 11, and the second connecting pipe 26 is connected to the second member 21, thereby enabling the first member 11, the first connecting pipe 16, the capillary member, the second connecting pipe 26, and the second member 21 to be in communication. The first member 11 has a third interface 110, and the second member 21 has a fourth interface 210. One end of the capillary member is in communication with the first interface. The length direction of the first fin 14 is substantially perpendicular to the length direction of the first heat exchange tube 13. In the direction of the air flow (the direction of the arrow shown in the figure), when the heat exchange assembly is in the working state, the first heat exchanger 10 serves as an evaporator, and the second heat exchanger 20 serves as a condenser. The air in the environment flows through the first heat exchanger 10, and the first heat exchanger 10 condenses the water vapor in the air to form condensed water. The dehumidified air flows through the condenser and is heated, and the heated air at a suitable temperature is discharged into the environment. The heating temperature of the condenser can be freely adjusted. In this way, the cycle is carried out to achieve dehumidification of the environment.

[0055] In some embodiments, such as Figures 1 - 2 、 Figures 7 - 8 the heat exchange assembly 100 shown, the heat exchange assembly 100 further includes a temperature sensing sleeve 40. The temperature sensing sleeve 40 is connected to the first member 11. The temperature sensing sleeve 40 can be used to place a temperature sensing package, and the temperature sensing package is used to measure the temperature of the first heat exchanger 10, so as to prevent the first heat exchanger 10 from freezing due to too low temperature, thereby affecting the heat exchange performance of the first heat exchanger 10, improving the working efficiency of the heat exchange assembly 100, and thus being beneficial to improving the heat exchange performance of the heat exchange assembly 100.

[0056] In some embodiments, such as Figures 10 - 12 the heat exchange assembly 100 shown, the heat exchange assembly 100 includes a first partition 27. To increase the flow path of the first assembly and the second heat exchanger 20, partitions 27 are provided inside the first member 11 and the second member 21. Therefore, the first member 11 and the second member 21 will form multiple chambers. Specifically, the first member 11 has a first chamber 111, and the partition 27 is located in the first chamber 111. Therefore, the partition 27 divides the first chamber 111 into multiple chambers. The first chamber 111 includes a first sub-chamber 1111 and a second sub-chamber 1112 that are mutually separated. The multiple first heat exchange tubes 13 include a first group of heat exchange tubes and a second group of heat exchange tubes. The multiple first channels 131 of the first group of heat exchange tubes are in communication with the first sub-chamber 1111, and the multiple first channels 131 of the second group of heat exchange tubes are in communication with the second sub-chamber 1112;

[0057] The second member 21 has a second chamber 211, and the partition 27 is located in the second chamber 211. Thus, the partition 27 divides the second chamber 211 into multiple chambers. The second chamber 211 includes a third sub-chamber 2111 and a fourth sub-chamber 2112 that are separated from each other. There are multiple second heat exchange tubes 23, and the multiple second heat exchange tubes 23 include a third group of heat exchange tubes and a fourth group of heat exchange tubes. The third group of heat exchange tubes communicates with the third sub-chamber 2111, and the fourth group of heat exchange tubes communicates with the fourth sub-chamber 2112.

[0058] In the height direction of the heat exchange assembly, the first sub-chamber 1111 is located below the second sub-chamber 1112, the third sub-chamber is located below the fourth sub-chamber, the first connecting pipe 16 communicates with the first sub-chamber 1111, and the second connecting pipe 26 communicates with the fourth sub-chamber.

In the height direction of the heat exchange assembly 100, the connection between the sixth member 28 and the second member 21 is close to the bottom of the second member 21. That is to say, it can be connected to the last process of the flow path of the heat exchange assembly. Or assuming that the last process is set as N, the sixth member 28 can also be set to communicate with the (N - 1)th process. When the sixth member 28 communicates with the Nth process or when the sixth member 28 communicates with the (N - 1)th process, it is beneficial for the heat exchange assembly in the working state. When the second heat exchanger 20 is in the working state of a condenser, when introducing the liquid refrigerant at the bottom of the sixth member 28 into the Nth process, or introducing the liquid refrigerant at the bottom of the sixth member 28 into the (N - 1)th process, it is beneficial to subcool the condenser and improve the heat exchange performance of the heat exchange assembly 100.

[0060] Specifically, such as Figure 10 As shown in the heat exchange assembly 100, the heat exchange assembly 100 further includes a sixth member 28.

In some embodiments, such as Figure 12The heat exchange component shown has the sixth component 28 connected to the second component 21. The second component 21 has a second chamber 211. The second chamber 211 includes a third sub-chamber and a fourth sub-chamber that are separated from each other. In the height direction of the heat exchange component 100, the third sub-chamber is located below the fourth sub-chamber, and the third sub-chamber communicates with the fifth sub-chamber 221.

[0061] In some embodiments, such as Figures 1 - 12 the heat exchange component 100 shown, the first heat exchanger 10 includes a first heat exchange tube 13, and the second heat exchanger 20 includes a second heat exchange tube 23. Specifically, as Figure 13 and Figure 14 shown, the first heat exchange tube 13 has a plurality of first channels 131.

The first heat exchange tube 13 includes a tube wall 132 and a partition member 133. The inner surface of the tube wall 132 is provided with a plurality of convex portions 134, and the outer surface of the partition member 133 is provided with a plurality of convex portions 134. When the first heat exchanger 10 is in a working state, the convex portions 134 not only facilitate the turbulence of the refrigerant but also increase the heat exchange area between the inner surface of the tube wall 132 and the refrigerant, thereby facilitating the improvement of the heat exchange performance of the first heat exchanger 10. The second heat exchange tube 23 has a plurality of second channels 231. By providing the plurality of second channels 231, the heat exchange area of the second heat exchanger 20 is increased, which is beneficial to improving the heat exchange performance of the heat exchange component 100.
