The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] Reference below Figure 1-Figure 8 An outdoor unit 100 according to an embodiment of the present invention is described. The outdoor unit 100 can be used in a HVAC device as a part of the HVAC device.

[0050] The compressor assembly 3 includes a compressor 30, and the compressor assembly 3 can play a role in compressing and driving the refrigerant in the refrigerant circulation loop. The outdoor fan 5 is used to drive air into the outdoor casing 1, and exchange heat with the outdoor heat exchanger 4, and then discharge it to the outside of the outdoor casing 1 after the heat exchange. For example, an air inlet 15 and an air outlet 16 are formed on the outdoor casing 1, and the outdoor fan 5 drives the air into the outdoor casing 1, and then exchanges heat with the outdoor heat exchanger 4 and then discharges it to the outside of the outdoor casing 1 from the air outlet 16.

[0051] The water heat exchanger assembly 6 is adjacent to the first corner 2 of the outdoor housing 1. The water heat exchanger assembly 6 includes a water heat exchanger 60, which has a refrigerant flow path and a water flow path that can exchange heat with each other. In the process of the refrigerant flowing through the refrigerant flow path and the water flowing through the water flow path, the water in the water flow path can exchange heat with the refrigerant in the refrigerant flow path, so that the water flow can be heated or cooled, thereby realizing the heating or cooling function. The water heat exchanger 60 is provided with a water inlet 61 and a water outlet 62. The water inlet 61 of the water heat exchanger 60 is connected to a water inlet pipe 611, and the water outlet 62 of the water heat exchanger 60 is connected to a water outlet pipe 621. The water flow path connects the water inlet 61 and the water outlet 62. Water can flow into the water heat exchanger through the water inlet pipe 611 and the water inlet 61. After flowing through the water flow path in the water heat exchanger 60, the water is discharged from the water outlet 62 and the water outlet pipe 621. The water discharged from the water outlet pipe 621 can be introduced into the room to adjust the indoor ambient temperature or the temperature of the indoor domestic water.

[0052] The mounting cover plate 7 is provided to cover at least a portion of the opening 11, and the mounting cover plate 7 is used to cover the opening 11. For example, the mounting cover plate 7 is provided to cover a portion of the opening 11; or the mounting cover plate 7 is provided to cover the entire opening 11.

For example, the outlet tube plate 71 covers part of the first area 111, and the other part of the cover plate 7 except the outlet tube plate 71 covers the rest of the first area 111; for another example, the outlet tube plate 71 covers the entire first area 111. The outlet tube plate 71 is formed into a flat plate, and the outlet tube plate 71 covers at least part of the first area 111, so that the influence of the first corner 2 on the outlet pipe arrangement of the water inlet pipe 611 and the water outlet pipe 621 of the water heat exchanger 60 can be reduced, so that the water heat exchanger 60 can be arranged close to the first corner 2 of the outdoor casing 1, so as to make full use of the space at the first corner 2.

[0053] For example, the cross section of the outdoor housing 1 is formed into a quadrilateral, and the outdoor housing 1 includes a first side plate 13 and a back plate 12 adjacent to each other, and the first corner 2 is formed between the first side plate 13 and the back plate 12. An opening 11 is formed on the back plate 12 of the outdoor housing 1, and the mounting cover plate 7 is arranged on the opening 11 and includes a pipe outlet plate 71. The water inlet pipe 611 and the water outlet pipe 621 of the water heat exchanger 60 are discharged through the pipe outlet plate 71, which can reduce the influence of the first corner 2 on the pipe outlet setting of the water heat exchanger 60, so that the water heat exchanger 60 can be arranged close to the first corner 2, and the water heat exchanger 60 can be as close to the first side plate 13 as possible, so as to make full use of the space of the first corner 2 and avoid a large gap between the water heat exchanger 60 and the first side plate 13, so as to make full use of the internal space of the outdoor housing 1.

[0054] According to the outdoor unit 100 of the embodiment of the present invention, an opening 11 is formed on the peripheral wall of the outdoor unit 100, and the opening 11 passes through the first corner portion 2 along the thickness direction of the outdoor unit 100, and a mounting cover plate 7 including a tube outlet plate 71 is provided at the opening 11, so that the water inlet pipe 611 and the water outlet pipe 621 of the water heat exchanger 60 can both be discharged through the tube outlet plate 71, thereby reducing the obstruction of the first corner portion 2 on the arrangement of the water inlet pipe 611 and the water outlet pipe 621 of the water heat exchanger 60, thereby reducing the influence of the first corner portion 2 on the setting position of the water heat exchanger 60 in the outdoor unit 100, so that the water heat exchanger 60 can be set close to the first corner portion 2 to make full use of the space of the first corner portion 2, thereby making full use of the internal space of the outdoor machine casing 1, and rationally arranging the interior of the outdoor machine casing 1, which is conducive to realizing the miniaturized design of the outdoor unit 100.

[0055] According to some embodiments of the present invention, reference Figure 2-Figure 3 , Figure 6 In the circumferential direction of the outdoor housing 1, the first area 111 extends from one side of the first corner 2 in the circumferential direction to the other side of the first corner 2 in the circumferential direction. By setting the first area 111 to penetrate the first corner 2 in the circumferential direction, the space of the first corner 2 can be better utilized. When the outlet tube plate 71 covers the first area 111, the water inlet pipe 611 and the water outlet pipe 621 are not affected by the first corner 2 when they are discharged through the outlet tube plate 71. Then, the water circuit heat exchanger 60 can be well arranged close to the first corner 2, so as to make better use of the internal space of the outdoor housing 1, which is conducive to the reasonable layout of the interior of the outdoor unit 100 and the realization of the miniaturized design of the outdoor unit 100.

[0056] According to some embodiments of the present invention, reference Figure 2-Figure 3 , Figure 6, the opening 11 also includes a second area 112. In the circumferential direction of the outdoor housing 1, the second area 112 is located on one side of the first corner 2, and the outlet tube plate 71 covers at least part of the first area 111 and at least part of the second area 112. By setting the opening 11 as the first area 111 and the second area 112, and making the outlet tube plate 71 cover the first area 111 and the second area 112, the setting area of ​​the outlet tube plate 71 can be expanded, which is convenient for matching the size of the water circuit heat exchanger 60, so that the water inlet pipes 611 and the water inlet pipes 611 can be reasonably arranged on the outlet tube plate 71, and can be extended to the outside of the outdoor housing 1 through the outlet tube plate 71.

[0057] According to some embodiments of the present invention, reference Figure 2-Figure 3 , Figure 7 The outlet tube plate 71 is formed with a first tube hole 711 and a second tube hole 712. The water inlet pipe 611 is provided through the first tube hole 711, and the water outlet pipe 621 is provided through the second tube hole 712, so that the water inlet pipe 611 can extend to the outside of the outdoor housing 1 through the first tube hole 711, and the water outlet pipe 621 can extend to the outside of the outdoor housing 1 through the second tube hole 712. The outlet tube plate 71 includes a plate edge portion 714. In the circumferential direction of the outdoor housing 1, the plate edge portion 714 is located at one end of the outlet tube plate 71 close to the first corner portion 2. The plate edge portion 714 covers at least a portion of the first area 111, for example, the plate edge portion 714 covers a portion of the first area 111; or the plate edge portion 714 covers the entire first area 111. At least one of the first tube hole 711 and the second tube hole 712 passes through the plate edge portion 714.

[0058] Among them, at least one of the first tube hole 711 and the second tube hole 712 penetrates the plate edge 714, which may include the following situations: for example, the first tube hole 711 penetrates the plate edge 714, which may be part of the first tube hole 711 penetrates the plate edge 714, or the first tube hole 711 penetrates the plate edge 714; for example, the second tube hole 712 penetrates the plate edge 714, which may be part of the second tube hole 712 penetrates the plate edge 714, or the second tube hole 712 penetrates the plate edge 714; for example, the first tube hole 711 and the second tube hole 712 both penetrate the plate edge 714, and it can be that part of the first tube hole 711 and part of the second tube hole 712 penetrate the plate edge 714, or the entire first tube hole 711 and part of the second tube hole 712 penetrate the plate edge 714, or part of the first tube hole 711 and the entire second tube hole 712 penetrate the plate edge 714, or the entire first tube hole 711 and the entire second tube hole 712 penetrate the plate edge 714.

[0062] The second tube hole 712, the first tube hole 711 and the third tube hole 713 are arranged sequentially from top to bottom, so as to reasonably arrange the water outlet pipe 621, the water inlet pipe 611 and the sewage pipe 631 on the water heat exchanger 60. The second tube hole 712 is adjacent to the upper edge of the outlet tube plate 71, and the third tube hole 713 is adjacent to the lower edge of the outlet tube plate 71, so that the second tube hole 712, the first tube hole 711 and the third tube hole 713 can be reasonably arranged on the outlet tube plate 71, and the outlet tube plate 71 can be fully utilized, so as to reasonably reduce the size of the outlet tube plate 71, thereby reasonably reducing the size of the installation cover plate 7; and because the installation cover plate 7 is arranged at the opening 11 to cover the opening 11, the size of the opening 11 can also be reasonably reduced to reduce the influence of the opening 11 on the structural strength of the outdoor housing 1.

By providing the connecting flange 72 on the outer edge of the outlet tube plate 71, it is convenient to connect the installation cover plate 7 to the outdoor housing 1.

[0070] According to some optional embodiments of the present invention, reference Figure 2The connection flange 72 is connected to the outdoor housing 1 by a plurality of fasteners, and the plurality of fasteners are arranged at intervals along the circumference of the outlet tube plate 71. By arranging fasteners for connecting with the outdoor housing 1 at intervals along the circumference of the outlet tube plate 71, the stability of the connection relationship between the connection flange 72 and the outdoor housing 1 can be improved, thereby ensuring the stability of the relative position relationship between the outlet tube plate 71 and the outdoor housing 1. The installation cover plate 7 is connected to the outdoor housing 1 by fasteners, and the connection method is simple and the installation operation is easy.

[0071] According to some optional embodiments of the present invention, reference Figure 2-Figure 3 , Figure 7 The connecting flange 72 includes a first connecting flange 721 and a second connecting flange 722 arranged along the circumference of the outlet tube plate 71.

For example, the installation cover plate 7 is connected to the outdoor housing 1 by fasteners penetrating the outdoor housing 1 and the first connection flange 721, and by fasteners penetrating the outdoor housing 1 and the second flange portion 7222. By setting the first connecting flange 721 and the second flange part 7222, the first connecting flange 721 and the second flange part 7222 are located on the inner side of the outdoor casing 1. The relative positioning of the installation cover plate 7 and the outdoor casing 1 can be achieved through the abutment between the outdoor casing 1 and the first connecting flange 721 and the abutment between the outdoor casing 1 and the second flange part 7222, so that the installation cover plate 7 is easily connected to the outdoor casing 1. When the installation cover plate 7 is connected to the outdoor casing 1, scratches by the installation cover plate 7 can be avoided. After the installation cover plate 7 is connected to the outdoor casing 1, the appearance of the outdoor unit 100 is more beautiful.

[0073] According to some embodiments of the present invention, reference Figure 2-Figure 3 , Figure 7 The portion of the outlet tube plate 71 not covered in the first area 111 protrudes inward to form a convex portion 73, and the convex portion 73 is connected to the water circuit heat exchanger assembly 6. For example, a fastener is inserted through the convex portion 73 and the water circuit heat exchanger assembly 6 to connect the installation cover plate 7 to the water circuit heat exchanger assembly 6. Through the further connection between the convex portion 73 and the water circuit heat exchanger assembly 6, the installation stability and reliability of the installation cover plate 7 structure can be improved.
