[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0046] like Figure 1 As shown, Figure 1 An air conditioner 100 according to an embodiment of this application is shown. The air conditioner 100 includes a housing 1, a first heat exchanger 2, a second heat exchanger 3, and a first seal 4.

[0047] An air duct 11 is provided inside the housing 1. An air inlet 12 and an air outlet 13 are also provided on the housing 1. The air inlet 12 and the air outlet 13 are respectively located at opposite ends of the air duct 11. The air inlet 12 is used to input air into the air duct 11, and the air outlet 13 is used to exhaust air from the air duct 11.

[0048] The first heat exchanger 2, the second heat exchanger 3, and the first sealing element 4 are all disposed within the air duct 11. The first heat exchanger 2 and the second heat exchanger 3 are arranged sequentially along the air duct 11. Air flowing through the air duct 11 flows sequentially through the first heat exchanger 2 and the second heat exchanger 3, exchanging heat with them respectively. The first heat exchanger 2 includes a first side plate 21 and a first heat exchange tube. The first heat exchange tube can contain refrigerant, which exchanges heat with the air outside the first heat exchange tube as it flows along it. The first side plate 21 can be constructed as a generally flat plate. The first side plate 21 is provided with a plurality of first mounting holes 21, through which the first heat exchange tube meanders and is fixed to the first side plate 21, supporting the first heat exchange tube.

[0049] The second heat exchanger 3 includes a second side plate 31 and a second heat exchange tube. The second heat exchange tube can contain refrigerant, which exchanges heat with the air outside the tube as it flows along it. The second side plate 31 can be constructed as a generally flat plate. Multiple second mounting holes 32 are provided on the second side plate 31, through which the second heat exchange tube meanders and is fixed to the second side plate 31, which supports the second heat exchange tube.

[0050] Both the first heat exchanger 2 and the second heat exchanger 3 can function as evaporators. The first side plate 21 of the first heat exchanger 2 and the second side plate 31 of the second heat exchanger 3 are joined together. The first side plate 21 and the second side plate 31 are on the same vertical plane. The first side plate 21 and the second side plate 31 are connected to each other, forming a single flat plate. The first side plate 21 and the second side plate 31 can be connected by screws. The ends of the first side plate 21 and the second side plate 31 facing the same direction are not flush, so that the ends of the first side plate 21 and the second side plate 31 form a first notch 71. The shape of the first notch 71 is not limited.

[0051] like Figures 2-4 As shown, the first sealing element 4 includes a first sealing plate 40, a first connecting portion 41, and a second connecting portion 42. The first sealing plate 40 can be constructed as a flat plate. The first sealing plate 40 covers the first notch 71. The first sealing plate 40, the first side plate 21, and the second side plate 31 are parallel to each other. The shape of the first sealing plate 40 is not limited; the shape of the first sealing plate 40 can be the same as the shape of the first notch 71, or the shape of the first sealing plate 40 can be different from the shape of the first notch 71. If the shape of the first sealing plate 40 is the same as the shape of the first notch 71, the area of ​​the first sealing plate 40 can be reduced, thus reducing the manufacturing cost of the first sealing plate 40. The shape of the first sealing plate 40 and the shape of the first notch 71 can both be triangular. The first connecting portion 41 and the second connecting portion 42 are both disposed on the first sealing plate 40. The first connecting portion 41, the second connecting portion 42, and the first sealing plate 40 can be an integrally formed structure. The first connecting portion 41 is connected to the end of the first side plate 21 near the first notch 71. The second connecting portion 42 is connected to the end of the second side plate 31 near the first notch 71. The first connecting part 41 and the first side plate 21 can be connected by snap-fit, plug-in, screw connection, clip connection, welding or bonding. The second connecting part 42 and the second side plate 31 can be connected by snap-fit, plug-in, screw connection, clip connection, welding or bonding.

[0052] In this way, the first side plate 21 of the first heat exchanger 2 and the second side plate 31 of the second heat exchanger 3 are brought together, and a first notch 71 is formed between the ends of the first side plate 21 and the second side plate 31 that face the same direction. The first sealing plate 40 of the first sealing member 4 covers the first notch 71, sealing it and preventing air flowing from the first heat exchanger 2 to the second heat exchanger 3 from leaking out through the first notch 71, thereby improving the overall heat exchange efficiency of the first heat exchanger 2 and the second heat exchanger 3. The first connecting part 41 and the second connecting part 42 of the first sealing member 4 are respectively connected to the first side plate 21 and the second side plate 31, thereby fixing the first sealing plate 40 to the first notch 71. This fixing method is firm.

[0053] In one illustrative embodiment, the first connecting portion 41 and the second connecting portion 42 are disposed on the same surface of the first sealing plate 40. The first connecting portion 41 is connected to the side of the first sealing plate 40 near the first side plate 21. A first limiting groove 410 is provided on the first connecting portion 41. The first limiting groove 410 is a straight through groove. The first limiting groove 410 is parallel to the surface of the first side plate 21. The opening of the first limiting groove 410 faces the first side plate 21. The portion of the first side plate 21 near the first notch 71 extends into the first limiting groove 410. The width of the first limiting groove 410 may be equal to the thickness of the first side plate 21. The first limiting groove 410 may also be an interference fit with the first side plate 21.

[0054] The second side plate 31 has a snap-fit ​​groove near the first notch 71. The snap-fit ​​groove is a recess. The second connecting part 42 is constructed as a snap fastener, and the second connecting part 42 snaps into the snap-fit ​​groove on the second side plate 31. Thus, a snap-fit ​​connection is formed between the second connecting part 42 and the second side plate 31.

[0055] In this way, the first side plate 21 is inserted into the first limiting groove 410 of the first connecting part 41, preventing the first sealing member 4 from moving relative to the first side plate 21 and the second side plate 31 in a direction perpendicular to the first side plate 21. Furthermore, because the second connecting part 42 of the first sealing member 4 forms a snap-fit ​​connection with the second side plate 31, the first sealing member 4 cannot move relative to the first side plate 21 and the second side plate 31 in a direction parallel to the first side plate 21. Therefore, the cooperation between the first connecting part 41 and the second connecting part 42 allows the second sealing member 5 to be securely fixed to the first side plate 21 and the second side plate 31. Simultaneously, because the first connecting part 41 and the first side plate 21 are fitted together by an insertion, and the second connecting part 42 and the second side plate 31 are snap-fit ​​connected, the assembly of the first sealing member 4 with the first side plate 21 and the second side plate 31 is simple and improves assembly efficiency.

[0056] In an illustrative embodiment, the first side plate 21 includes a first side edge 210. The first side edge 210 is located on the side of the first side plate 21 closest to the second side plate 31. The second side plate 31 includes a second side edge 310. The second side edge 310 is located on the side of the second side plate 31 closest to the first side plate 21. Both the first side edge 210 and the second side edge 310 of the first side plate 21 are straight strips. The first side edge 210 of the first side plate 21 and the second side edge 310 of the second side plate 31 are adjacent to each other.

[0057] The extension direction of the first limiting groove 410 on the first connecting part 41 is parallel to the extension direction of the first side edge 210 of the first side plate 21. The first side edge 210 of the first side plate 21 abuts against the bottom of the first limiting groove 410.

[0058] In this way, since the extending direction of the first limiting groove 410 is parallel to the extending direction of the first side 210, and the first side 210 abuts against the bottom of the first limiting groove 410, when installing the first seal 4, it is only necessary to fit the first limiting groove 410 of the first seal 4 onto the first side 210 so that the first side 210 abuts against the bottom of the first limiting groove 410, and then slide the first seal 4 along the first side 210 towards the second side plate 31 until the second connecting part 42 is snapped into the snap groove of the second side plate 31, thus completing the installation of the first seal 4. The installation process is simple. At the same time, after the installation is completed, the bottom of the groove of the first seal 4 abuts against the first side 210 as a whole, making the installation of the first seal 4 more stable.

[0059] In an illustrative embodiment, the first connecting portion 41 further includes a first base plate 411 and a first side plate 412. Both the first base plate 411 and the first side plate 412 are constructed as flat plates. One end of the first base plate 411 is connected to the surface of the first sealing plate 40. There is a gap between the edges of the first base plate 411 and the first sealing plate 40. The surface of the first base plate 411 is perpendicular to the first sealing plate 40 and parallel to the extending direction of the first side edge 210. The first side plate 412 is connected to the end of the first base plate 411 away from the first sealing plate 40. The first side plate 412 is parallel to the first sealing plate 40. The first base plate 411, the first sealing plate 40, and the first side plate 412 enclose a first limiting groove 410. The first base plate 411 serves as the bottom wall of the first limiting groove 410, and the first sealing plate 40 and the first side plate 412 respectively serve as the two opposite side walls of the first limiting groove 410. This structure of the first connecting portion 41 is simple and has low manufacturing cost.

[0060] In one illustrative embodiment, the second connecting portion 42 includes an elastic arm 421 and a snap-on plate 422. The elastic arm 421 may be configured as a strip plate. One end of the elastic arm 421 is connected to the side of the first sealing plate 40 near the second side plate 31. The elastic arm 421 is inclined relative to the first sealing plate 40. The snap-on plate 422 is configured as a flat plate. One end of the snap-on plate 422 is connected to the end of the elastic arm 421 away from the first sealing plate 40. The snap-on plate 422 is parallel to the first sealing plate 40. The snap-on plate 422 is accommodated within a snap-on groove in the second side plate 31.

[0061] The second connecting part 42 of this structure is simple in structure and low in manufacturing cost. At the same time, it can firmly fasten the groove of the second side plate 31.

[0062] In one illustrative embodiment, the ends of the first side plate 21 and the second side plate 31 away from the first seal 4 are not flush, so that the ends of the first side plate 21 and the second side plate 31 away from the first seal 4 enclose a second notch 72. The shape of the second notch 72 is not limited.

[0063] The air conditioner 100 also includes a second sealing element 5. The second sealing element 5 is disposed within the air duct 11 of the housing 1. The second sealing element 5 includes a second sealing plate 50, a third connecting portion 51, and a fourth connecting portion 52. The second sealing plate 50 can be constructed as a flat plate. The second sealing plate 50 covers the second notch 72. The second sealing plate 50, the first side plate 21, and the second side plate 31 are parallel to each other. The shape of the second sealing plate 50 is not limited; the shape of the second sealing plate 50 can be the same as the shape of the second notch 72, or the shape of the second sealing plate 50 can be different from the shape of the second notch 72. If the shape of the second sealing plate 50 is the same as the shape of the second notch 72, the area of ​​the second sealing plate 50 can be reduced, thus reducing the manufacturing cost of the second sealing plate 50. The shape of the second sealing plate 50 and the shape of the second notch 72 can both be triangular. The third connecting portion 51 and the fourth connecting portion 52 are both disposed on the second sealing plate 50. The third connecting portion 51, the fourth connecting portion 52, and the second sealing plate 50 can be an integrally formed structure. The third connecting portion 51 is connected to the end of the first side plate 21 near the second notch 72. The fourth connecting part 52 is connected to the end of the second side plate 31 near the second notch 72. The third connecting part 51 and the first side plate 21 can be connected by snap-fit, plug-in, screw connection, snap-fit ​​connection, welding or bonding. The fourth connecting part 52 and the second side plate 31 can be connected by snap-fit, plug-in, screw connection, snap-fit ​​connection, welding or bonding.

[0064] Thus, a second notch 72 is formed between the ends of the first side plate 21 and the second side plate 31 furthest from the first seal 4. The second sealing plate 50 of the second seal 5 covers the second notch 72, sealing it and preventing air flowing from the first heat exchanger 2 to the second heat exchanger 3 from leaking out through the second notch 72. This further improves the overall heat exchange efficiency of the first heat exchanger 2 and the second heat exchanger 3. The third connecting portion 51 and the fourth connecting portion 52 of the second seal 5 are respectively connected to the first side plate 21 and the second side plate 31, thereby fixing the second sealing plate 50 to the second notch 72. This fixing method is secure.

[0065] In an illustrative embodiment, the first side plate 21 and the second side plate 31 are constructed as straight strips. The two ends of the first side plate 21 of the first heat exchanger 2 abut against the inner wall of the air duct 11. The first side plate 21 of the first heat exchanger 2 may be inclined within the air duct 11, and its two ends may abut against the top and bottom walls of the air duct 11, respectively. The two ends of the second side plate 31 of the second heat exchanger 3 abut against the inner wall of the air duct 11, respectively. The second side plate 31 of the second heat exchanger 3 may be inclined within the air duct 11, and its two ends may abut against the top and bottom walls of the air duct 11, respectively. The openings of the first notch 71 and the second notch 72 located at opposite ends of the first side plate 21 and the second side plate 31 are both covered by the inner wall of the air duct 11. The side of the first sealing plate 40 closest to the opening of the first notch 71 abuts against the inner wall of the air duct 11. The side of the second sealing plate 50 near the opening of the second notch 72 abuts against the inner wall of the air duct 11.

[0066] In this way, the first sealing plate 40 and the second sealing plate 50 abut against the inner wall of the air duct 11, and the first sealing plate 40 and the second sealing plate 50 cannot be dislodged from the opening of the first notch 71 and the opening of the second notch 72 respectively, so the first sealing plate 40 and the second sealing plate 50 can be installed more securely.

[0067] In one illustrative embodiment, the third connecting portion 51 is provided with a second limiting groove 510. The second limiting groove 510 is a straight through groove. The opening of the second limiting groove 510 faces the first side plate 21, and the portion of the first side plate 21 near the second notch 72 extends into the second limiting groove 510. The width of the second limiting groove 510 can be equal to the thickness of the first side plate 21. The second limiting groove 510 can also be an interference fit with the first side plate 21.

[0068] like Figures 5-7 As shown, the fourth connecting part 52 is provided with a third limiting groove 520 with an opening facing the second side plate 31, and the second side plate 31 extends into the third limiting groove 520.

[0069] The third limiting groove 520 is a straight through groove. The opening of the third limiting groove 520 faces the second side plate 31, and the portion of the second side plate 31 near the second notch 72 extends into the third limiting groove 520. The width of the third limiting groove 520 can be equal to the thickness of the second side plate 31. The third limiting groove 520 can also be an interference fit with the third side plate.

[0070] In this way, the first side plate 21 is inserted into the second limiting groove 510 of the third connecting part 51, and the second side plate 31 is inserted into the third limiting groove 520 of the fourth connecting part 52, so that the second sealing member 5 is fixed relative to the first side plate 21 and the second side plate 31. This fixing method is simple and easy to implement. At the same time, the second sealing member 5 also abuts against the inner wall of the air duct 11, so that the first side plate 21 cannot come out of the second limiting groove 510, and the second side plate 31 cannot come out of the third limiting groove 520. The second sealing member 5 can be firmly fixed and will not fall off.

[0071] In an illustrative embodiment, the third limiting groove 520 of the fourth connecting portion 52 extends parallel to the second side edge 310 of the second side plate 31, and the second side edge 310 abuts against the bottom of the third limiting groove 520. The extending direction of the second limiting groove 510 is perpendicular to the extending direction of the third limiting groove 520. The second limiting groove 510 abuts against the end face of the first side plate 21 near the second notch 72.

[0072] In this way, since the extension direction of the second limiting groove 510 and the extension direction of the third limiting groove 520 on the second sealing member 5 are perpendicular to each other, the second sealing member 5 cannot move along the extension direction of the second limiting groove 510, nor can it slide along the extension direction of the third limiting groove 520, and the second sealing member 5 is fixed more securely.

[0073] In one illustrative embodiment, such as Figures 5-7 As shown, the third connecting portion 51 also includes a second side plate 511 and a third side plate 512. The second side plate 511 and the third side plate 512 are parallel to each other and both parallel to the second sealing plate 50. The second side plate 511 and the third side plate 512 are spaced apart, and the end of the second sealing plate 50 near the first side plate 21 is sandwiched between the second side plate 511 and the third side plate 512. The ends of the second side plate 511 and the third side plate 512 facing the same direction are respectively connected to the two opposite plate surfaces of the second sealing plate 50. The second side plate 511, the third side plate 512, and the second sealing plate 50 enclose the second limiting groove 510. The second side plate 511 and the third side plate 512 respectively serve as the opposite two side walls of the second limiting groove 510, and the end face of the second sealing plate 50 serves as the bottom wall of the second limiting groove 510. This structure of the third connecting portion 51 is simple and has low manufacturing cost.

[0074] In an illustrative embodiment, the fourth connecting portion 52 further includes a fourth side plate 521 and a fifth side plate 522. Both the fourth side plate 521 and the fifth side plate 522 are constructed as flat plates. The fourth side plate 521 and the fifth side plate 522 are parallel to each other and parallel to the second sealing plate 50. The fourth side plate 521 and the fifth side plate 522 are spaced apart, and the end of the second sealing plate 50 near the second side plate 31 is sandwiched between the fourth side plate 521 and the fifth side plate 522. The ends of the fourth side plate 521 and the fifth side plate 522 facing the same direction are respectively connected to the two opposite surfaces of the second sealing plate 50. The fourth side plate 521, the fifth side plate 522, and the second sealing plate 50 enclose a third limiting groove 520. The fourth side plate 521 and the fifth side plate 522 respectively serve as the opposite two side walls of the third limiting groove 520, and the end face of the second sealing plate 50 serves as the bottom wall of the third limiting groove 520. This structure of the fourth connecting portion 52 is simple and has low manufacturing cost.

[0075] In one illustrative embodiment, a lug 24 is provided on the first side plate 21. The lug 24 may be constructed as a plate-like structure. The lug 24 is located on the side of the first side plate 21 near the second side plate 31. The lug 24 extends from the side of the first side plate 21 near the second side plate 31 toward the second side plate 31. The lug 24 overlaps with the second side plate 31. The lug 24 is fixedly connected to the second side plate 31. The connection between the lug 24 and the second side plate 31 may be by screws, welding, or riveting.

[0076] In this way, the first side plate 21 and the second side plate 31 are brought together, and the first side plate 21 can be connected to the second side plate 31 through the lug 24. This connection method is simple. Compared with the connection method in the prior art that uses a connecting plate to connect the first side plate 21 and the second side plate 31, the connection method in this embodiment eliminates the connecting plate, reduces the number of parts, and simplifies the component structure.

[0077] In another illustrative embodiment, a lug (not shown) is provided on the second side plate 31. The lug can be constructed as a plate-like structure.
