These phrases appearing in various places throughout the specification do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0071] This utility model embodiment provides a heat exchange unit 110, which can be applied to duct air conditioners, and of course, can also be applied to other suitable heat exchange equipment.

[0072] like Figure 1 and Figure 2 As shown, the heat exchange unit 110 includes a heat exchange component 1, a first water receiving tray 2, and a first flow guiding component 3. The heat exchange component 1 forms an air duct 11 for exchanging heat with the air entering the air duct 11. It should be noted that the heat exchange described here can be heat exchange during the cooling process or heat exchange during the heating process, and is not particularly limited here.

[0073] For example, taking the application of heat exchange unit 110 in a ducted air conditioner as an example, heat exchange unit 110 may have a first installation state and a second installation state, wherein the first installation state may be the horizontal installation state of the ducted air conditioner (see Figure 9 For example, the fan is located on the outlet side of the heat exchange assembly, and both are horizontally installed. The second installation configuration can be a vertical installation of the ducted air conditioner (see...). Figure 10 For example, the fan is located on the outlet side of the heat exchange assembly, and both are installed vertically.

[0074] Correspondingly, heat exchange component 1 may also have a first installation state (see Figure 9 ) and second installation state (see Figure 10 ).

[0075] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the heat exchange assembly 1 includes at least one heat exchanger group 12, wherein the heat exchanger group 12 has an open end 121 and a splicing end 122, and the open end 121 and the splicing end 122 are arranged sequentially from the air inlet side to the air outlet side.

[0076] For example, the heat exchange assembly 1 generally has an air inlet (not shown in the figure) and an air outlet (not shown in the figure). Air can enter the air duct 11 through the air inlet, and after heat exchange, it exits the air duct 11 through the air outlet. The air inlet side mentioned herein is the side where air enters the air duct 11, and correspondingly, the air outlet side is the side where the heat-exchanged air exits the air duct 11. Among them, the open end 121 of the heat exchanger assembly 12 is close to the air inlet side, and the splicing end 122 is close to the air outlet side.

[0077] Also exemplarily, the splicing end 122 of the heat exchanger assembly 12 generally has a gap groove 123 on the side opposite to the opening end 121. For example, the heat exchanger assembly 12 includes two heat exchangers (not shown in the figure) arranged in a V-shape. On the air outlet side of the heat exchange assembly 1, after one end of the two heat exchangers is joined, a gap groove 123 can be formed together on the side opposite to the opening end 121 to form the splicing end 122 of the heat exchanger assembly 12. On the air inlet side of the heat exchange assembly 1, the other ends of the two heat exchangers are open to each other to jointly form the opening end 121 of the heat exchanger assembly 12.

[0078] It should be noted that, for ease of description, the three mutually perpendicular directions in space are defined as the first direction 300, the second direction 400, and the third direction 500. The first direction 300 can be defined as the direction from the air inlet side to the air outlet side, or the air outlet direction (which can correspond to...). Figure 1 The vertical direction in the middle). The second direction 400 can be defined as the extension direction of the gap groove 123 (which can correspond to the vertical direction in the middle). Figure 1 The front-to-back direction in the middle), the third direction 500 can be defined as the direction in which the two heat exchangers open relative to each other (which can correspond to the direction of the two heat exchangers opening relative to each other). Figure 1 (The left and right directions in the middle).

[0079] In embodiments of this utility model, such as Figure 1 As shown, the first drip tray 2 is connected to one side (e.g., the left or right side) of the heat exchange assembly 1. The first drip tray 2 is primarily used to receive condensate dripping from the heat exchange assembly 1 when it is in its first installation state. For example, when the heat exchange unit 110 is in its first installation state (see...) Figure 9 The first water receiving tray 2 is located at the bottom of the heat exchange component 1 and can be used to receive the condensate falling from the heat exchange component 1.

[0080] To reduce the occurrence of condensate overflow in the heat exchange unit 110 during the first installation state, such as Figure 2 , Figure 3 and Figure 9 As shown, the first flow guiding component 3 is located on the air outlet side of the heat exchange component 1. Exemplarily, on the air outlet side of the heat exchange component 1, the first flow guiding component 3 is connected to the splicing end 122 of the heat exchange component 1.

[0081] In addition, to ensure that the air after heat exchange can be discharged from the air outlet side of the air duct 11, the first flow guide assembly is provided with an air outlet clearance 34. Understandably, the air after heat exchange in the air duct 11 of the heat exchange assembly 1 needs to pass through the clearance 34 of the first flow guide assembly 3 and be blown out of the heat exchange assembly 1.

[0082] like Figure 2 , Figure 3 and Figure 9As shown, the first flow guiding component 3 includes at least one first baffle 31, the first baffle 31 including a first baffle portion 311, wherein the first baffle portion 311 can extend into the gap groove 123 from the air outlet side and engage with the gap groove 123 to fill the gap groove 123 as much as possible, so as to prevent part of the air from passing through the slot of the gap groove 123 and escaping out of the heat exchange component 1, thereby preventing this part of the air from carrying the condensate out of the heat exchange component 1 along the extension direction of the gap groove 123 (corresponding to the second direction 400).

[0083] In addition, since the air after heat exchange needs to pass through the clearance opening 34 of the first flow guiding assembly 3, in order to prevent the condensate water condensed on the first baffle 311 and its surrounding area from passing through the corresponding position of the clearance opening 34 during the fall, the first flow guiding assembly 3 also includes a first flow guiding member. The first flow guiding member is located on the periphery of the clearance opening 34, and the condensate water on the first baffle 311 in the first installation state can be guided to the first water receiving tray 2 through the first flow guiding member.

[0084] Understandably, in the first installation state, when the condensate condensed at the first baffle 311 and its surrounding area falls under the action of gravity, if it will pass through the corresponding position of the avoidance opening 34, the first guide member can guide the falling condensate from the periphery of the avoidance opening 34 to the first water receiving tray 2 before it falls to the corresponding position of the avoidance opening 34, so as to prevent it from being directly carried out of the heat exchange component 1 by the wind through the avoidance opening 34.

[0085] It should be noted that, as Figure 1 and Figure 2 As shown, the heat exchange unit 110 also includes a refrigerant sensor 7, which is disposed on the heat exchange component 1 and used to monitor the state of the refrigerant in the heat exchange component 1. The refrigerant sensor 7 mentioned here includes, but is not limited to, a pressure sensor and a temperature sensor.

[0086] In summary, compared with existing technologies, the heat exchange unit 110 has at least the following beneficial effects:

[0087] The heat exchange unit 110 can be connected to the first flow guide component 3 on the air outlet side of the heat exchange component 1, and an air supply and outlet clearance port 34 is formed on the first flow guide component 3. The first baffle 31 of the first flow guide component 3 extends from the air outlet side into the gap groove 123 of the splicing end 122 of the corresponding heat exchanger group 12. The gap groove 123 is filled by the concave and convex cooperation between the first flow guide component 3 and the gap groove 123, so as to prevent part of the air from passing through the slot of the gap groove 123 and running out of the heat exchange component 1. This can prevent the part of the air from carrying the condensate out of the heat exchange component 1 along the extension direction of the gap groove 123 (corresponding to the second direction 400).

[0088] In addition, the heat exchange unit 110 can also guide the condensate condensed at the first baffle 311 and its surrounding position in the first installation state to the first water receiving tray 2 through the first guide member located around the avoidance port 34, so as to prevent the condensate from falling through the corresponding position of the avoidance port 34 and being directly carried out of the heat exchange assembly 1 by the wind from the avoidance port 34.

[0089] Overall, the heat exchange unit 110, through the cooperation of the first flow guiding component 3 and the first flow guiding element, can effectively prevent the condensate formed at and near the splicing end 122 of the heat exchanger group 12 from overflowing. This helps to ensure that the condensate of the heat exchange component 1 does not easily overflow, and there is no need to use gaskets or other sealing structures for sealing. This simplifies the structure of the heat exchange unit 110 and the manufacturing process.

[0090] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 10 The technical solutions in the embodiments of this utility model are clearly and completely described below. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0091] In some embodiments, such as Figure 2 and Figure 3 As shown, the shape of the first baffle 311 is similar to the groove shape of the gap groove 123. Understandably, the external structure of the first baffle 311 can mimic the groove shape of the gap groove 123 so that the first baffle 311 and the gap groove 123 can fit together in a concave-convex manner, so as to minimize the air movement between the first baffle 311 and the gap groove 123 after heat exchange.

[0092] In some embodiments, the projection of the first baffle 311 along the extending direction of the gap groove 123 (which may correspond to the second direction 400) covers the corresponding position of the gap groove 123 and the air leakage hole 16 on the heat exchange assembly 1 (see figure). Figure 7 ).

[0093] It should be noted that, since the heat exchange component 1 usually has a small hole (corresponding to the air leakage hole 16) at the corresponding position of the gap groove 123 at the splicing end 122, it has been found that the air after heat exchange can easily escape from the heat exchange component 1 through the small hole. When it escapes from the heat exchange component 1, it often carries the condensate near the splicing end 122 of the heat exchanger group 12 out of the first water receiving tray 2.

[0094] Understandably, by ensuring that the first stop 311 is in the second direction 400 (specifically, it can be...) Figure 1 The projection of the heat exchange assembly 1 onto the heat exchanger 1 in the front-to-back direction covers the air leakage hole 16 (see) Figure 7 This allows the solid cross-section of the first baffle 311 to directly block the air leakage hole 16, preventing air from escaping from the air leakage hole 16 and carrying the condensate water out and falling to the outside of the first water receiving tray 2.

[0095] In some embodiments, such as Figure 2 and Figure 3 As shown, the first guide member also includes a first guide portion 312 with a guide groove 3121. In the first installation state, the first guide portion 312 is located on the side of the first baffle 311 near the first water receiving tray 2 (specifically, it can correspond to...). Figure 9 The guide groove 3121 (located on the lower side of the first baffle 311) can be used to receive the condensate falling from the first baffle 311 and guide the received condensate from one end to the other end to the first water receiving tray 2.

[0096] For example, the first baffle 311 extends along the second direction 400, and the first guide portion 312 also extends along the second direction 400, so that the first guide portion 312 can guide the condensate on the first baffle 311 in a direction perpendicular to the air outlet direction (corresponding to the second direction 400). When the heat exchange unit 110 is in the first installation state (see...), Figure 9 As air passes through the first guide assembly 3 and is discharged from the air duct 11, the condensate formed on the first baffle 311 can fall directly into the guide groove 3121 of the first guide part 312 under the action of gravity, so that it can fall from the end of the guide groove 3121 to the first water receiving tray 2.

[0097] Optionally, in order to ensure that the first guide section 312 can smoothly guide the flow, the guide groove 3121 can be configured such that its other end gradually deviates from the first stop section 311 towards the corresponding second guide section 31, so that the guide groove 3121 is inclined relative to the first stop section 311. In this way, the condensate received in the guide groove 3121 can be guided from one end of the guide groove 3121 to the other end to the corresponding second guide section 31.

[0098] It should be noted that, to ensure that the condensate on the first baffle 311 is evenly received by the guide groove 3121 of the first guide section 312, when the heat exchange unit 110 is in the first installation state, the projection of the first baffle 311 in the direction of gravity can fall completely within the guide groove 3121. Similarly, to ensure that the condensate received in the guide groove 3121 can fall into the corresponding second guide section 31 without overflowing outside the second guide section 31, when the heat exchange unit 110 is in the first installation state, the projection of the end of the first guide section 312 in the direction of gravity can fall completely within the corresponding second guide section 31.

[0099] Optionally, the first stop portion 311 and the first guide portion 312 can be welded or integrally formed into the first stop member 31. In this way, compared to connecting them with screws or other threaded components, the structure of integrally forming the first stop portion 311 and the first guide portion 312 eliminates the time spent fixing screws during manufacturing, thus reducing production costs. Of course, in other embodiments, the first stop portion 311 and the first guide portion 312 can also be integrally formed using other suitable methods, which are not particularly limited here.

[0100] In some embodiments, such as Figure 3 As shown, in order to enable the flow guide trough 3121 to achieve unidirectional flow in a direction perpendicular to the air outlet direction (corresponding to the second direction 400), the flow guide trough 3121 of the first flow guide part 312 has a first end 31211 and a second end 31212. In the direction from the first end 31211 to the second end 31212, the size of the flow guide trough 3121 gradually decreases. The condensate water received by the first flow guide part 312 can flow from the first end 31211 to the second end 31212 and be guided to the first water receiving tray 2.

[0101] Understandably, the first end 31211 is a wide-mouth end, mainly used to receive more condensate. Correspondingly, the second end 31212 is a narrow-mouth end, mainly used to centrally discharge the condensate in the guide channel 3121 to the corresponding second guide section 31.

[0102] For example, the flow channel 3121 of the first flow guide 312 can be formed by bending the free edge of the first flow guide 312, and the bending shape is gradually changing so that the port of the first end 31211 is larger than the port of the second end 31212.

[0103] In some embodiments, such as Figure 2 and Figure 3 As shown, the first guide member also includes a second guide section 31, wherein the second guide section 31 is recessed with a guide channel, which is mainly used to receive the condensate water falling from the guide groove 3121 and guide the received condensate water to the first water receiving tray 2 in the direction from the air outlet side to the air inlet side.

[0104] For example, such as Figure 9 As shown, the second guide section 31 is located between the outer wall of the heat exchange assembly 1 and the inner side of the first water receiving tray 2. When the heat exchange unit 110 is in the first installation state, condensate from the splicing end 122 and other locations of the heat exchange assembly 1 can be guided by the second guide section 31 to the first water receiving tray 2 in the opposite direction (i.e., against the wind) of the first direction 300, to prevent condensate from the splicing end 122 of the heat exchange assembly 1 from falling outside the first water receiving tray 2, which could easily lead to condensate overflowing from the air outlet. In some embodiments, such as Figure 3 As shown, there are two second guide sections 31.

[0105] The flow channel of the second flow guide 31 is designated as the first flow guide channel 321, and the first flow guide channel 321 is correspondingly configured with the first end 31211 of the flow guide groove 3121. The flow channel of the other second flow guide 31 is designated as the second flow guide channel 322, and the second flow guide channel 322 is correspondingly configured with the second end 31212 of the flow guide groove 3121.

[0106] The size of the second guide channel 322 is larger than that of the first guide channel 321. Understandably, when the port of the first end 31211 is larger than the port of the second end 31212, the condensate in the guide channel 3121 mainly falls from the second end 31212 to the second guide channel 322 of the other second guide section 32, rather than falling into the first guide channel 321 of the second guide section 32. Thus, by adapting the size of the second guide channel 322 to be larger than that of the first guide channel 321, it is beneficial to ensure that the condensate falling from the second end 31212 is received by the second guide channel 322 as much as possible, preventing overflow.

[0107] In some embodiments, to improve the flow guiding efficiency of each second flow guiding section 31, the first flow guiding channel 321 and the second flow guiding channel 322 are both inclined from the air outlet side to the air inlet side in the first installation state (see...). Figure 9 ).

[0108] In some embodiments, such as Figures 1 to 4 As shown, to improve the overall integrity and stability of the first flow guiding component 3, the first flow guiding component 3 also includes a bracket 33. The bracket 33 is connected to the heat exchange component 1 on the air outlet side, and the first baffle 31 is connected to the bracket 33.

[0109] The first guide member includes at least one second guide portion 32, which extends in the direction from the air outlet side to the air inlet side. Each second guide portion 32 is connected to the bracket 33 and is arranged with gaps along the length direction of the first baffle 31 (which may correspond to the second direction 400).

[0110] For example, the bracket 33 can be detachably connected to the heat exchange component 1 via threaded components such as screws, bolts, or snap-fit ​​connections for easy disassembly, assembly, and maintenance. Similarly, the first stop 31 can also be detachably connected to the bracket 33 via threaded components such as screws, bolts, or snap-fit ​​connections. Of course, in other embodiments, other suitable methods can be used for connection, which are not particularly limited here.

[0111] Optionally, there may be two second guide sections 32. Of course, in other embodiments, there may be more second guide sections 32. The number of second guide sections 32 is not particularly limited here, and can be determined according to actual needs.

[0112] In some embodiments, such as Figure 3 and Figure 4 As shown, to further improve the overall integrity, stability, and compactness of the first airflow guiding component 3, the bracket 33 includes a first support member 331 and a second support member 332. The first support member 331 and the second support member 332 are spaced apart and arranged side-by-side along the length direction of the first stop member 31 (corresponding to the second direction 400). The first stop member 31 is located between the first support member 331 and the second support member 332. Understandably, the first support member 331, the second support member 332, and the first stop member 31 can jointly define the air discharge clearance opening 34 within the air supply duct 11.

[0113] Additionally, a second flow guide 32 is welded to the ends of the first support member 331 and the second support member 332 on the same side. Exemplarily, the end of the first support member 331 near the corresponding second flow guide 32 can be spot-welded to one second flow guide 32 via a fixing plate (not shown in the figure), and correspondingly, the end of the second support member 332 near the corresponding second flow guide 32 can also be spot-welded to another second flow guide 32 via another fixing plate (not shown in the figure). Of course, in other embodiments, the first support member 331 and the second support member 332 can be directly welded to the corresponding second flow guide 32.

[0114] Understandably, compared to the fixed connection achieved by threaded parts such as screws, bolts, and bolts, the first support 331 and the second support 332 are fixed to the corresponding second guide part 32 by welding. On the one hand, this can save an assembly part, which helps to reduce material costs. On the other hand, it can also save the installation time of threaded parts, which helps to improve the assembly efficiency of the heat exchange unit 110 and reduce production costs.

[0115] In some embodiments, such as Figure 3 and Figure 4 As shown, to further improve the overall integrity, stability, and compactness of the first flow guiding component 3, the bracket 33 includes a first support member 331 and a second support member 332. The first support member 331 and the second support member 332 are arranged side by side with a gap along the length direction of the first baffle 31 (which can correspond to the second direction 400), and each end on the same side is connected to a second flow guiding part 32. In this way, when the heat exchange unit 110 is in the first installation state, the condensate on the first support member 331 and the second support member 332 can fall to the corresponding second flow guiding part 32 under the action of gravity.

[0116] Furthermore, the first support member 331 extends a first preset width toward the second support member 332, and the second support member 332 extends a second preset width toward the first support member 331. This ensures that when air is discharged from the duct 11 through the first guide assembly 3, the condensate carried in the air adheres as much as possible to the first and second support members 331 and is guided to the corresponding drip trays, preventing the condensate in and around the first guide assembly 3 from being carried out of the duct 11 by the air passing through it.

[0117] In some embodiments, such as Figure 5 As shown, the first water receiving tray 2 has a recessed first water receiving cavity 21 on the side near the heat exchange component 1. The first water receiving cavity 21 has a drain outlet 211, which is mainly used to discharge the condensate in the first water receiving cavity 21. For example... Figure 5 As shown, at least two reinforcing ribs 22 are protruding inside the first water receiving cavity 21. Each reinforcing rib 22 is located at the corresponding position of the drain outlet 211, and each reinforcing rib 22 extends from the air inlet side to the air outlet side and is arranged side by side with gaps along the length direction of the first baffle 31.

[0118] Understandably, on the one hand, the reinforcing ribs 22 protruding in the first water receiving cavity 21 can enhance the strength of the first water receiving tray 2; on the other hand, by arranging at least two reinforcing ribs 22 side by side along the length direction of the first stop 31 (which can correspond to the second direction 400), the drain outlet 211 can be defined by at least one drainage channel by the two adjacent reinforcing ribs 22, which facilitates the guidance of condensate in the first water receiving cavity 21 to the drain outlet 211 for discharge, thereby facilitating the discharge of condensate in the first water receiving cavity 21 as soon as possible, and preventing condensate in the first water receiving cavity 21 from being easily splashed out by newly falling condensate due to difficulty in discharge.

[0119] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, to improve the heat exchange efficiency of the heat exchange unit 110, the number of heat exchanger groups 12 is at least two, with each heat exchanger group 12 arranged in a row and the opening end 121 of each heat exchanger group 12 facing the same side (specifically, corresponding to the air inlet side). Each first baffle 31 corresponds one-to-one with the gap groove 123 of each heat exchanger group 12. For example, if there are two heat exchanger groups 12, and each heat exchanger group 12 has one gap groove 123, then there are also two first baffles 31. The first baffle portion 311 of the two first baffles 31 can respectively engage with the gap groove 123 of the corresponding heat exchanger group 12.

[0120] like Figure 2 , Figure 6 and Figure 7As shown, to form the air duct 11, the heat exchange assembly 1 also includes a first sealing bracket 13 and a second sealing bracket 14. The two heat exchangers (not shown in the figure) in each heat exchanger group 12 are connected at the open end 121 by two oppositely arranged first sealing brackets 13. Each heat exchanger group 12 and the corresponding two first sealing brackets 13 can together form a first heat exchange channel (not shown in the figure).

[0121] Correspondingly, two adjacent heat exchanger groups 12 are connected at the splicing end 122 by two opposing second sealing supports 14. The two adjacent heat exchanger groups 12 and their corresponding second sealing supports 14 together form a second heat exchange channel (not shown in the figure). At the junction of two adjacent heat exchanger groups 12, the first heat exchange channel and the second heat exchange channel communicate to jointly form an air duct 11.

[0122] For example, such as Figure 6 and Figure 7 As shown, in the extending direction of the gap groove 123 (corresponding to the second direction 400), among the two first sealing supports 13 corresponding to each heat exchanger group 12, one of the first sealing supports 13 is on the front side of the heat exchanger group 12 (see...). Figure 6 A first sealing bracket 13 is located between two heat exchangers in heat exchanger assembly 12 to connect the two heat exchangers; correspondingly, another first sealing bracket 13 is located on the rear side of heat exchanger assembly 12 (see...). Figure 7 Located between the two heat exchangers of the heat exchanger group 12, so as to connect the two heat exchangers. In this way, on the air inlet side of the heat exchanger group 12, the two heat exchangers and the corresponding two first sealing brackets 13 can jointly form the first heat exchange channel.

[0123] For example, such as Figure 6 and Figure 7 As shown, in the extending direction of the gap groove 123 (corresponding to the second direction 400), among the two second sealing supports 14 corresponding to two adjacent heat exchanger groups 12, one of the second sealing supports 14 is on the front side of the heat exchanger group 12 (see...). Figure 6 A second sealing bracket 14 is located between two heat exchanger groups 12 to connect the two heat exchanger groups 12; correspondingly, another second sealing bracket 14 is located on the rear side of the heat exchanger group 12 (see...). Figure 7 Located between two heat exchanger groups 12, so as to connect the two heat exchanger groups 12, so that on the air outlet side of the heat exchanger group 12, the inner sidewalls of the two heat exchanger groups 12 and the corresponding two second sealing supports 14 can jointly form a second heat exchange channel.

[0124] In this embodiment, as Figure 1 , Figure 2 and Figure 8As shown, to receive condensate generated by the heat exchange unit 110 in the second installation state, the heat exchange unit 110 further includes a second water receiving tray 4. The second water receiving tray 4 is connected to the heat exchange assembly 1 on the air inlet side, and has at least two communicating second water receiving cavities 41 with openings facing the heat exchange assembly 1. Each second water receiving cavity 41 corresponds one-to-one with the heat exchanger group 12 and is used to receive condensate falling from the corresponding heat exchanger group 12 in the second installation state. The second water receiving tray 4 has air guide holes 42 at corresponding positions of each first heat exchange channel, and each second water receiving cavity 41 is arranged around the corresponding air guide hole 42.

[0125] For example, there are two heat exchanger groups 12, arranged in a straight line along a third direction 500°. Correspondingly, there are also two second water receiving chambers 41 in the second water receiving tray 4, and two air guide holes 42 in the second water receiving tray 4. One second water receiving chamber 41 of the second water receiving tray 4 is arranged around one air guide hole 42, with two heat exchangers of one heat exchanger group 12 positioned within the corresponding location of the air guide hole 42, and the air guide hole 42 communicating with the first heat exchange channel of the heat exchanger group 12. Similarly, the other second water receiving chamber 41 of the second water receiving tray 4 is arranged around another air guide hole 42, with two heat exchangers of the other heat exchanger group 12 positioned within the corresponding location of the air guide hole 42, and the air guide hole 42 communicating with the first heat exchange channel of the heat exchanger group 12. Furthermore, the two heat exchanger groups 12 form a second heat exchange channel on the air outlet side. In short, when there are two heat exchanger groups 12, the heat exchange assembly 1 has two first heat exchange channels and one second heat exchange channel.

[0126] Understandably, air can enter the corresponding first heat exchange channel from the two air guide holes 42, and then enter the second heat exchange channel from the corresponding first heat exchange channel to merge, so as to ultimately realize that air enters the air duct 11 from the air inlet side and exits the air duct 11 from the air outlet side.

[0127] In some embodiments, to further prevent condensate overflow from the heat exchange assembly 1, such as Figure 6 and Figure 7 As shown, the heat exchange unit 110 also includes a second flow guiding component 5, which is disposed within the second heat exchange channel and is used to guide the condensate condensed at the edge of the heat exchange component 1 into the heat exchange component 1. For example, the condensate condensed at the edge of the heat exchange component 1 can be directly collected in the air duct 11 by the second flow guiding component 5, and the collected condensate can be reintroduced into the air duct 11 by the second flow guiding component 5, so that it can be finally received by the first water receiving tray 2 or the second water receiving tray 4, instead of being carried out of the air duct 11 by the air directly.

[0128] In some embodiments, such as Figure 6As shown, the second flow guiding assembly 5 includes a second flow guiding member 51, wherein the second flow guiding member 51 is disposed on a second sealing bracket 14 along the air outlet direction. Exemplarily, the second flow guiding member 51 is built into the second heat exchange channel along the air outlet direction (corresponding to the first direction 300), and the second flow guiding member 51 can guide the received condensate into the air duct 11 along the counter-wind direction.

[0129] In some embodiments, such as Figure 7 As shown, the second flow guiding assembly 5 includes a third flow guiding member 52, which is disposed on another second sealing bracket 14 along the air outlet direction (corresponding to the first direction 300). Exemplarily, the third flow guiding member 52 is built into the second heat exchange channel along the air outlet direction, and the third flow guiding member 52 can also guide the received condensate into the air duct 11 along the counter-wind direction.

[0130] For example, specifically in this embodiment, the second flow guiding component 5 includes a second flow guiding member 51 and a third flow guiding member 52, wherein the second flow guiding member 51 and the third flow guiding member 52 are disposed opposite to each other and are parallel to each other. Of course, in other embodiments, the two may not be parallel or may be disposed offset.

[0131] It should be noted that in some examples, a water-guiding structure can also be formed on the port of the side plate (not shown in the figure) of the heat exchange component 1 to prevent the condensate of the heat exchange component 1 from overflowing. The specific structure of the water-guiding structure on the side plate is not particularly limited here. In another example, a target water-guiding structure can be set at a suitable location such as the air duct 11 to prevent the condensate of the heat exchange component 1 from overflowing. The specific structure of this target water-guiding structure can be an existing structure or a newly created structure, and is not particularly limited here. Its specific placement is also not particularly limited, as long as it effectively prevents the condensate of the heat exchange component 1 from overflowing.

[0132] In some embodiments, to prevent the first sealing bracket 13 and the second sealing bracket 14 from being installed incorrectly during assembly, at least one of the first sealing bracket 13 and the second sealing bracket 14 is provided with a first foolproof structure (not shown in the figure).

[0133] For example, such as Figure 6 and Figure 7 As shown, in the finished product state, the first sealing bracket 13 is an equilateral triangle bracket 33, and the second sealing bracket 14 is an inverted triangle bracket 33. However, during assembly, the equilateral triangle bracket 33 and the inverted triangle bracket 33 are easily confused. To prevent installation errors, a first foolproof structure can be provided on the first sealing bracket 13 and / or the second sealing bracket 14 to achieve a 180° foolproof design for both. For example, a mark can be provided on the first sealing bracket 13 (second sealing bracket 14) to distinguish it from the second sealing bracket 14 (first sealing bracket 13).

[0134] The markings mentioned herein include, but are not limited to, raised areas, grooves, text, and patterns. No particular limitation is made here, as long as they serve the purpose of identification and differentiation.

[0135] In some embodiments, to prevent air leakage in the first heat exchange channel, each first sealing bracket 13 is conformally fitted to the heat exchanger assembly 12. For example, as shown... Figure 6 As shown, the edges of each first sealing bracket 13 can be designed to conform to the shape of the gap hole (not shown in the figure) formed between the two heat exchangers of each heat exchanger group 12, so as to achieve a seamless connection between each first sealing bracket 13 and the two heat exchangers of each heat exchanger group 12.

[0136] like Figure 6 As shown, there is a gap 15 at the junction of two adjacent heat exchanger groups 12. The gap 15 is located between two adjacent air guide holes 42 of the second water receiving tray 4 and communicates with the second water receiving cavity 41. Understandably, after air enters the corresponding first heat exchange channel from each air guide hole 42, it can enter the second heat exchange channel through the gap 15. In the existing heat exchange unit 110, the area corresponding to this gap is generally a negative pressure area. When air passes through the gap 15, it is easy for air to blow up the condensate in the second water receiving cavity 41.

[0137] To prevent water from blowing at the location corresponding to gap 15, such as Figure 2 , Figure 8 and Figure 10 As shown, the heat exchange unit 110 also includes a second baffle 6, which is disposed within the gap 15 along the extension direction of the gap 15 (corresponding to the second direction 400) to prevent condensate from the edges of each heat exchanger assembly 12 from being blown out of the second water receiving tray 4 from the gap 15. Understandably, the second baffle 6 is disposed within the second water receiving cavity 41 of the second water receiving tray 4 along the second direction 400, and can seal the gap 15.

[0138] For example, such as Figure 8 and Figure 10 As shown, the second baffle 6 includes a second baffle portion 61. The end of the second baffle portion 61 near the air outlet side is a blind end, and the end near the air inlet side has an opening. The opening of the second baffle portion 61 can communicate with the second water receiving cavity 41. Understandably, the condensate at the corresponding position of the gap 15 in the second water receiving cavity 41 can be blocked from the second heat exchange channel by the blind end of the second baffle portion 61, so as to prevent the condensate at the gap from being blown into the second heat exchange channel and carried out of the air duct 11, and to prevent the condensate at the gap from being blown up and splashed outside the second water receiving cavity 41.

[0139] In some examples, such as Figure 8 and Figure 10As shown, the second baffle 6 is conformally adapted to the convex and concave shape of the gap 15. Exemplarily, the second baffle 6 and the gap 15 are conformally fitted, and the shape of the second baffle portion 61 of the second baffle 6 can be conformally shaped to the shape of the gap 15 so that the second baffle 6 can be seamlessly joined with the two adjacent heat exchanger groups 12, thereby helping to prevent water blowing at the connection of the two adjacent heat exchanger groups 12.

[0140] In some examples, such as Figure 8 As shown, the second stop 6 is provided with a second foolproof structure. For example, the second stop 6 also includes connecting ears 62. Connecting ears 62 are connected to both sides (specifically the left and right sides) of the first stop 311. Each connecting ear 62 is provided with a first connecting hole 621. Correspondingly, a second connecting hole (not shown in the figure) is provided at the corresponding position of the second water receiving tray 4. The second stop 6 can be connected to the second water receiving tray 4 by inserting screws, bolts, or other threaded parts into the first connecting hole 621 and the second connecting hole.

[0141] To prevent the second stop 6 from being installed backwards, the two corresponding first connecting holes 621 on the connecting ear 62 can be designed to be asymmetrically arranged. For example, the distance between the first connecting hole 621 of one connecting ear 62 and the first stop 311 in the third direction 500 is larger, while the distance between the first connecting hole 621 of the other connecting ear 62 and the first stop 311 in the third direction 500 is smaller. Similarly, the second connecting hole is also opened in this manner. In this way, the second stop 6 can achieve the left-right misalignment prevention effect, preventing the second stop 6 from being assembled incorrectly after delivery, thereby ensuring the product yield rate.

[0142] Of course, in other examples, other methods can be used to prevent left and right mistakes of the second stop 6. For example, the first connecting hole 621 on the connecting ear 62 can be misaligned, or a mark can be set on at least one side of the connecting ear 62 to distinguish the left and right sides of the second stop 6.

[0143] Based on the heat exchange unit 110 described above, this utility model embodiment also provides a heat exchange module 100, wherein the heat exchange module 100 includes the heat exchange unit 110 described above and a housing 120, and the heat exchange unit 110 is built into the housing 120.

[0144] Based on the heat exchange module 100 described above, this utility model embodiment also provides an air handling unit 1000, wherein the air handling unit 1000 includes the heat exchange module 100 and a drive module 200, wherein the drive module 200 is located on the air outlet side of the heat exchange unit 110 of the heat exchange module 100 and is used to generate airflow that exchanges heat with the heat exchange module 100.

[0145] It should be noted that the air handling unit 1000 includes, but is not limited to, a split-pipe air conditioner.

[0146] In summary, compared with the prior art, the heat exchange module 100 and the air handling unit 1000 have at least the following advantages: by adopting the heat exchange unit 110 described above, the heat exchange module 100 is less prone to condensate overflow, and the anti-overflow structure is simple and reliable, which helps to simplify the overall structure and manufacturing process of the heat exchange module 100 and the air handling unit 1000.

[0147] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
