[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The following combination Figures 1 to 6 The structure of the air conditioner outdoor unit of the present invention will be described.

[0039] like Figures 1 to 6As shown, a specific embodiment of the first aspect of the present invention provides an air-conditioning outdoor unit. The air-conditioning outdoor unit includes an outer casing 110, an electrical control box 120, and an air guide mechanism 130. A fan cavity 112 is formed inside the outer casing 110; a first air inlet 101 is provided on the outer casing 110; the electrical control box 120 is located on one side of the fan cavity 112; the air guide mechanism 130 includes a first air guide assembly 131; the first air guide assembly 131 is connected to the electrical control box 120; a first air guide channel is formed inside the first air guide assembly 131; an electric control radiator 127 of the electrical control box 120 is installed in the first air guide channel, the air inlet of the first air guide channel is connected to the first air inlet 101; and the air outlet of the first air guide channel is connected to the fan cavity 112.

[0040] In this embodiment, a first air guide assembly 131 having a first air guide channel formed therein is provided. The air inlet of the first air guide channel is connected to the first air inlet hole 101, and the air outlet of the first air guide channel is connected to the fan chamber 112. This design allows external cold air entering from the first air inlet hole 101 to be directed through the first air guide channel to the electronically controlled radiator 127. The cold air and the electronically controlled radiator 127 exchange heat, thereby improving the heat dissipation capacity of the electronically controlled radiator 127. The airflow after heat dissipation can be actively sucked and discharged by the fan installed in the fan chamber 112, forming an overall "air inlet-heat dissipation-exhaust" path, namely the first air duct. This design not only improves the heat exchange efficiency of the electronically controlled radiator 127 of the electronic control box 120, thereby improving the heat dissipation capacity of the electronic control box 120, solving the problem of limited heat dissipation capacity of the electronic control box 120 in the air conditioner outdoor unit in the prior art, but also reduces energy loss caused by airflow turbulence.

[0041] In addition, without changing the overall structure of the air conditioner outdoor unit, the air guide mechanism 130 can be added by utilizing the available installation space inside the unit to improve the heat dissipation capacity of the electric control box 120 .

[0042] Optionally, the outer casing 110 includes side panels, a top panel and a bottom panel; the top panel and the bottom panel of the outer casing 110 are arranged at intervals in the up and down directions, the upper ends of the side panels of the outer casing 110 are connected to the top panel, and the lower ends of the side panels are connected to the bottom panel, and the side panels, the top panel and the bottom panel together form the outer casing 110.

[0043] Optionally, the side panels include a left side panel, a right side panel, a front side panel and a rear side panel connected end to end.

[0044] Optionally, the electric control radiator 127 of the electric control box 120 is installed on the outside of the electric control box 120 .

[0045] Optionally, there are multiple first air inlet holes 101, and the multiple first air inlet holes 101 are arranged at intervals in the up and down directions.

[0046] Optionally, the shape of the first air inlet 101 may be circular, elliptical, or polygonal. In the specific embodiment of the present invention, the shape of the first air inlet 101 is not limited.

[0047] like Figure 2 As shown, optionally, a compressor cavity 113 is further formed in the outer casing 110; the compressor cavity 113 is located on one side of the fan cavity 112, and the electrical control box 120 is located above the compressor cavity 113. An opening is formed at the lower end of the electrical control box 120, and the inner cavity of the electrical control box 120 is connected to the compressor cavity 113 through the opening. The compressor cavity 113 is located on one side of the fan cavity 112, and the electrical control box 120 is located above the compressor cavity 113. This fully utilizes the upper and lower spaces of the outer casing 110, avoids additional occupation of the fan cavity 112 or other key areas, makes the overall layout more compact, and can fully utilize the internal space of the outer casing 110. When the compressor is running, the temperature inside its cavity will rise due to the heat generated by the compressor, but the temperature of the compressor cavity 113 is usually lower than that of the electric control module board 125 and the electric control main control board 126 of the electric control box 120. Therefore, an opening is formed at the lower end of the electric control box 120 so that the inner cavity of the electric control box 120 is connected to the compressor cavity 113. The opening allows the cold air in the compressor cavity 113 to naturally rise and enter the inner cavity of the electric control box 120, forming a passive heat dissipation airflow, thereby improving the heat dissipation effect of the electric control box 120.

[0048] like Figure 2 As shown, in one embodiment, the first air guide assembly 131 is mounted on the outer side of the back panel of the electrical control box 120. Mounting the first air guide assembly 131 on the outer side of the electrical control box 120 avoids occupying the internal space of the electrical control box 120. Mounting the first air guide assembly 131 on the back panel of the electrical control box 120 fully utilizes the front and rear space of the outer housing 110, making the entire machine more compact.

[0049] like Figure 2 As shown, the air conditioner outdoor unit optionally further includes a middle partition 111; an installation cavity is formed within the outer casing 110; the middle partition 111 is installed in the installation cavity to separate the installation cavity into a fan cavity 112 and a compressor cavity 113; the compressor cavity 113 is located to the right of the fan cavity 112. The electrical control box 120 is located above the compressor cavity 113, and the lower end of the left side panel of the electrical control box 120 is connected to the upper end of the middle partition 111; a first air guide assembly 131 is installed on the outer side of the back side panel of the electrical control box 120. A first air inlet 101 is formed in the right side panel of the outer casing 110; the air inlet of the first air guide channel faces the first air inlet 101.

[0050] In one embodiment, a second air inlet 102 is provided on the outer housing 110, and the second air inlet 102 is connected to the compressor cavity 113. A second air outlet 121 is provided on the side of the electrical control box 120 near the fan cavity 112, and the second air outlet 121 is connected to the fan cavity 112. External cold air enters the compressor cavity 113 directly through the second air inlet 102. The external cold air passes through the compressor pipe assembly, absorbing the heat generated by the high-temperature pipes to prevent the electrical control box 120 from being baked. After exchanging heat with the high-temperature pipes, the air enters the electrical control box 120 from the bottom opening of the electrical control box 120, and enters the fan cavity 112 from the second air outlet 121 of the electrical control box 120. It is discharged under the suction of the fan, thus forming a second air duct. The first air duct and the second air duct can cooperate to further improve the heat dissipation effect of the electrical control box 120.

[0051] Optionally, there are multiple second air inlet holes 102, and the multiple second air inlet holes 102 are arranged at intervals in the up and down directions.

[0052] Optionally, the second air inlet hole 102 may be circular, elliptical, or polygonal in shape. In the specific embodiment of the present invention, the shape of the second air inlet hole 102 is not limited.

[0053] Optionally, a second air inlet 102 is defined on the right side panel of the outer housing 110. The second air inlet 102 is located below the first air inlet 101 and communicates with the first air guide duct. The second air inlet 102 communicates with the compressor chamber 113. A second air outlet 121 is defined on the left side panel of the electrical control box 120 (i.e., the side panel adjacent to the fan chamber 112). The second air outlet 121 is used to connect the fan chamber 112 with the inner cavity of the electrical control box 120.

[0054] In one embodiment, a third air outlet 122 is provided on the back panel of the electrical control box 120, and the third air outlet 122 communicates with the first air duct. Cold air from the outside enters the compressor chamber 113 through the second air inlet 102, and then enters the electrical control box 120 through the bottom opening. At least some of the air can enter the first air duct through the third air outlet 122, which, in conjunction with the second air duct, achieves multi-directional heat dissipation for the electrical control box 120.

[0055] Optionally, a second air outlet 121 is provided on the left side panel of the electric control box 120, and a third air outlet 122 is provided on the back side panel of the electric control box 120. The heat exchange air entering the electric control box 120 from the opening of the electric control box 120 may partially enter the fan cavity 112 from the second air outlet 121, and may also partially enter the first air guide channel from the third air outlet 122, so that the heat exchange air can be discharged from the electric control box 120 from different directions, thereby realizing heat dissipation of the electric control box 120 in different directions, and further improving the heat dissipation effect of the electric control box 120.

[0056] Optionally, the back panel of the electrical control box 120 is further provided with a fourth air outlet 123; the fourth air outlet 123 and the third air outlet 122 are spaced apart in the vertical direction, and the fourth air outlet 123 is connected to the first air guide channel. The design of the fourth air outlet 123 further increases the flow path of the heat exchange air and can cooperate with the third air outlet 122 to achieve heat dissipation in the upper and lower spaces of the electrical control box 120. External cold air enters the compressor chamber 113 from the second air inlet 102. The cold air passes through the pipe assembly components in the compressor to cool the high-temperature pipes. The air after heat exchange enters the electrical control box 120 from the bottom opening of the electrical control box 120. Part of the heat exchange air entering the electrical control box 120 may pass through the fourth air outlet 123 to remove heat from the bottom of the electrical control box 120; part of the heat exchange air may pass through the third air outlet 122 to remove heat from the top of the electrical control box 120. Air exhausted from the third and fourth air outlets 122, 123, enters the first air duct and ultimately the fan chamber 112. Air is then discharged from the outer housing 110 by the fan, thus forming a third air duct. In this embodiment, the three air ducts provide comprehensive heat dissipation for the electrical control box 120. This not only removes heat generated by the electrical control box 120 itself, but also removes heat generated by the high-temperature piping within the compressor chamber 113. This significantly reduces the temperature rise of components within the electrical control box 120, extending their service life.

[0057] like Figure 4 and Figure 5 As shown, in one embodiment, the air guide mechanism 130 further includes a second air guide assembly 132; a second air guide channel is formed within the second air guide assembly 132, the air inlet of the second air guide channel is connected to the air outlet of the first air guide channel, and the air outlet of the second air guide channel is connected to the fan chamber 112; the second air guide assembly 132 is mounted on the outer side of a side panel of the electrical control box 120 near the fan chamber 112 and is connected to the first air guide assembly 131. This design can prevent hot air generated by the heat exchanger of the entire machine from entering the air guide channel during high-temperature cooling, thereby affecting the heat dissipation efficiency of the electrical control box 120.

[0058] Specifically, the first air guide assembly 131 is mounted on the outer side of the back panel of the electrical control box 120. One end of the first air guide assembly 131 faces the right side panel of the outer casing 110, and the other end extends leftward to the left edge of the back panel of the electrical control box 120. The second air guide assembly 132 is mounted on the left side panel of the electrical control box 120. One end of the second air guide assembly 132 is connected to the other end of the first air guide assembly 131. The other end of the second air guide assembly 132 extends forward and, together with the first air guide assembly 131, forms an air guide mechanism 130 having an "L"-shaped cross-section. The outdoor heat exchanger of the air conditioner outdoor unit is usually mounted on the rear side of the fan chamber 112 and the compressor chamber 113. By providing the second air guide assembly 132, the air outlet of the air guide duct can be moved away from the outdoor heat exchanger, preventing the hot air generated by the outdoor heat exchanger from entering the air guide duct.

[0059] Optionally, the first air guide assembly 131 includes a first air guide cover, which is disposed on the outer side of the back panel of the electrical control box 120 and forms a first air guide channel with the back panel. The first air guide cover and the back panel of the electrical control box 120 forming the first air guide channel together can reduce material costs.

[0060] Optionally, the second air guide assembly 132 includes a second air guide cover; the second air guide cover is arranged on the outer side surface of the left side panel of the electrical control box 120, and is enclosed with the left side panel of the electrical control box 120 to form a second air guide duct; the rear end of the second air guide cover is also connected to the first air guide cover to connect the first air guide duct with the second air guide duct.

[0061] like Figures 3 to 6 As shown, in one embodiment, the electric control box 120 includes the electric control box 120 body, the electric control module board 125, and the electric control main board 126; the electric control box 120 body is located on one side of the fan chamber 112; the first air guide assembly 131 is connected to the electric control box 120 body; the electric control module board 125 and the electric control main board 126 are both located inside the electric control box 120 body and are respectively installed on two different side panels of the electric control box 120 body. In this embodiment, the electric control module board 125 and the electric control main board 126 are respectively installed on two different side panels of the electric control box 120 body. This not only avoids the concentration of high-heat-generating components and reduces thermal coupling effects, but also reduces electromagnetic interference and thermal interference. The first air guide assembly 131 can provide targeted heat dissipation for heat sources on different side panels. The first air guide assembly 131 is arranged on the outside of the electric control box 120 body and does not occupy the internal space of the electric control box 120 body, ensuring neat wiring inside the box.

[0062] It should be noted that the electric control module board 125 is mainly responsible for power execution, and the electric control main control board 126 is mainly responsible for intelligent control.

[0063] Optionally, the main body of the electric control box 120 includes a front panel, a back panel, a left panel and a right panel; the front panel, the back panel, the left panel and the right panel enclose an inner cavity; the electric control module board 125 with a larger heat generation is installed on the back panel, and the electric control module board 125 with a smaller heat generation is installed on the front panel. This front-to-back layout can reduce the size of the air-conditioning outdoor unit in the up and down directions; at the same time, the first air guide and electric control radiator 127 installed on the outer side of the back panel of the main body of the electric control box 120 are used to realize timely heat dissipation of the electric control module board 125.

[0064] Optionally, a third air outlet 122 is provided on the upper side of the back panel of the electric control box 120 body, a fourth air outlet 123 is provided on the lower side of the back panel of the electric control box 120 body, and a second air outlet 121 is provided on the left side panel of the electric control box 120 body.

[0065] Optionally, there are multiple second air outlets 121 , and the multiple second air outlets 121 are arranged at intervals in the up-down direction.

[0066] Optionally, there are multiple third air outlets 122 , and the multiple third air outlets 122 are arranged at intervals along the left-right direction.

[0067] Optionally, there are multiple fourth air outlets 123 , and the multiple fourth air outlets 123 are arranged at intervals along the left-right direction.

[0068] It should be noted that a plurality means at least two.

[0069] Optionally, the second air outlet 121 may be in a circular, elliptical, or polygonal shape. In the specific embodiment of the present invention, there is no limitation on the shape of the second air outlet 121.

[0070] Optionally, the shape of the third air outlet 122 may be circular, elliptical, or polygonal. In the specific embodiment of the present invention, there is no limitation on the shape of the third air outlet 122.

[0071] Optionally, the shape of the fourth air outlet 123 may be circular, elliptical, or polygonal. In the specific embodiment of the present invention, there is no limitation on the shape of the fourth air outlet 123.

[0072] like Figure 7As shown, in some embodiments, the air conditioner outdoor unit includes an outer casing 110, a casing heat exchange assembly 140, and a compressor assembly 150. The casing heat exchange assembly 140 includes a casing heat exchanger 141 and a casing bracket 142; the casing heat exchanger 141 is mounted on the outer casing 110 via the casing bracket 142. The compressor assembly 150 includes a compressor 151 and a compressor bracket 152; a casing mounting cavity is formed in the compressor bracket 152, and the compressor 151 is mounted on the upper end of the compressor bracket 152. The compressor 151 is located outside the casing mounting cavity, and the casing heat exchange assembly 140 is located inside the casing mounting cavity; an inlet and outlet are formed on the side of the compressor bracket 152, and the inlet and outlet are connected to the casing mounting cavity for allowing the casing heat exchange assembly 140 to enter and exit the casing mounting cavity.

[0073] In this embodiment, by providing a casing bracket 142, the casing heat exchanger 141 can be mounted on the outer housing 110, achieving a modular design for the casing bracket 142 and the casing heat exchanger 141. The casing heat exchanger 141 can be assembled and disassembled by assembling the casing bracket 142. By providing a press bracket 152, the compressor 151 is mounted on the bottom plate of the outer housing 110 between the compressors, achieving a modular design for the compressor 151 and the press bracket 152. The compressor 151 can be assembled and disassembled by assembling the press bracket 152. By installing the casing heat exchange assembly 140 in the casing mounting cavity within the press bracket 152 and installing the compressor 151 at the upper end of the press bracket 152, outside the casing mounting cavity, this vertical arrangement of the compressor 151 and the casing heat exchanger 141 fully utilizes the upper and lower space within the outer housing 110, avoiding occupying space in other directions of the outer housing 110. By opening an inlet and outlet connected to the sleeve installation cavity on the side of the compressor bracket 152, the sleeve heat exchange assembly 140 can be allowed to enter and exit the sleeve installation cavity as a whole through the inlet and outlet. When the sleeve heat exchange assembly 140 needs to be repaired or disassembled, the compressor 151 and the pipe group connected to the compressor 151 can be avoided from being disassembled, thereby reducing the maintenance cost and solving the defect of difficult disassembly and assembly of the air-conditioning outdoor unit in the prior art.

[0074] In some embodiments, the outer casing 110 includes side panels, a top panel, and a bottom panel; the top panel and the bottom panel of the outer casing 110 are arranged at intervals in the up and down directions, the upper ends of the side panels of the outer casing 110 are connected to the top panel, and the lower ends of the side panels are connected to the bottom panel, and the side panels, the top panel, and the bottom panel together form the outer casing 110.

[0075] Optionally, the side panels include a left side panel, a right side panel, a front side panel and a rear side panel connected end to end.

[0076] Optionally, an installation cavity is formed in the outer casing 110, and a middle partition 111 is installed in the installation cavity to separate the installation cavity into a fan cavity and a compressor cavity; the compressor cavity is located on the right side of the fan cavity, and the fan cavity is located on the left side of the middle partition 111; the sleeve heat exchange assembly 140 and the compressor assembly 150 are both located in the compressor cavity.

[0077] like Figure 8 and Figure 9 As shown, in some embodiments, the press support 152 includes a press support member 1524 and a press connector 1525. The press support member 1524 has a sleeve mounting cavity formed therein. The bottom of the press support member 1524 abuts against the bottom plate of the outer housing 110. The compressor 151 is mounted on the upper end of the press support member 1524. An inlet and outlet are defined on the side of the press support member 1524. The press connector 1525 is located on one side of the press support member 1524. The press connector 1525 is mounted on the bottom plate and connected to the press support member 1524.

[0078] In this embodiment, the compressor support member 1524 directly supports the compressor 151 and abuts the bottom plate of the outer casing 110 through its bottom, forming a stable vertical support. The compressor connector 1525 is independently fixed to the bottom plate and connected to the side of the compressor support member 1524 to provide lateral reinforcement to prevent the bracket from shifting or deforming due to vibration during the operation of the compressor 151.

[0079] Optionally, the lower end of the press support 1524 can be folded along the radial direction of the shell and tube heat exchanger 141 to form a press connector 1525. This integrated design can not only reduce the number of parts and components, reduce material costs, reduce stress concentration, but also improve the overall rigidity of the press bracket 152.

[0080] like Figure 8 and Figure 9 As shown, optionally, the press support 1524 includes a plurality of press support plates 15241 and a press mounting plate 15242; the plurality of press support plates 15241 are arranged around the central axis of the shell and tube heat exchanger 141; the upper ends of the plurality of press support members 1524 are connected to the press mounting plate 15242 to form a shell and tube mounting cavity; the lower end of the press support plate 15241 abuts against the bottom plate of the outer casing 110.

[0081] Exemplarily, the press support 1524 includes three press support plates 15241; the three press support plates 15241 are respectively a left press support plate, a front press support plate and a rear press support plate; the left press support plate is located on the left side of the shell and tube heat exchanger 141, the front press support plate is located on the front side of the shell and tube heat exchanger 141, and the rear press support plate is located on the rear side of the shell and tube heat exchanger 141; an inlet and outlet are formed between the front press support plate and the rear press support plate. In other words, the inlet and outlet are located on the right side of the shell and tube heat exchanger 141. With such a design, when the shell and tube heat exchanger 141 needs to be disassembled or repaired, it is only necessary to first remove the right side plate of the outer casing 110 to expose the inlet and outlet to the sight of the maintenance personnel, making it easier for the shell and tube heat exchange assembly 140 to enter and exit the outer casing 110, simplifying the difficulty of disassembly and assembly and reducing maintenance costs.

[0082] Optionally, the press connector 1525 is located on a side of the press support 1524 away from the shell and tube heat exchanger 141. Compared to the solution of arranging the press connector 1525 between the press support 1524 and the shell and tube heat exchanger 141, this design of arranging the press connector 1525 on the side of the press support 1524 away from the shell and tube heat exchanger 141 makes it easier for personnel to disassemble and assemble the press bracket 152, further reducing the difficulty of disassembly and assembly.

[0083] Optionally, the press connector 1525 is detachably connected to the base plate. For example, the press connector 1525 can be detachably connected to the base plate by screws.

[0085] like Figure 11 and Figure 12 As shown, optionally, the press connector 1525 is connected to the base plate by a limiting structure 153. This can improve the installation stability of the press bracket 152 and the base plate, and at the same time play a positioning role, making it easier to thread the press connector 1525 with the base plate.

[0086] Optionally, the limiting structure 153 includes a limiting hole and a limiting protrusion; one of the limiting hole and the limiting protrusion is set on the press connector 1525, and the other is set on the bottom plate.

[0087] For example, the left press connecting plate of the press connecting member 1525 has a limit hole, and a limit protrusion is formed on the bottom plate, which is inserted into the limit hole. During installation, the limit hole of the left press connecting plate can be first matched with the limit protrusion on the bottom plate to achieve pre-positioning, and then the left press connecting plate and the bottom plate can be screwed together.

[0088] Optionally, the compressor connector 1525 further includes a front compressor connector plate and / or a rear compressor connector plate. The front compressor connector plate is located between the shell-and-tube heat exchanger 141 and the front compressor support plate, with the front side of the front compressor connector plate connected to the front compressor support plate. The rear compressor connector plate is located between the shell-and-tube heat exchanger 141 and the rear compressor support plate, with the rear side of the rear compressor connector plate connected to the rear compressor support plate. This design avoids occupying space in the front-to-back direction of the outer casing 110, facilitating a thinner design for the air conditioner outdoor unit.

[0089] It should be noted that the double-tube heat exchanger 141 belongs to the prior art and will not be described in detail here. A valve seat is installed on the right side of the double-tube heat exchanger 141; the water inlet valve of the double-tube heat exchanger 141 is installed on the valve seat.

[0090] In some embodiments, the sleeve heat exchanger 141 is sleeved on the outside of the sleeve bracket 142. In other words, the sleeve bracket 142 is located in the center hole of the sleeve heat exchanger 141. Such a design can further reduce the installation space occupied, which is conducive to the miniaturization design of the air conditioner outdoor unit.

[0091] In some other embodiments, the sleeve bracket 142 is located outside the sleeve heat exchanger 141.

The first sleeve connector 1422 is independently fixed to the bottom plate and laterally connected to the side of the first sleeve support member 1421 to provide lateral reinforcement.

[0094] Optionally, the first sleeve support 1421 is located in the center hole of the sleeve heat exchanger 141, and the first sleeve support 1421 is connected to the inner side of the sleeve heat exchanger 141, and the lower end of the first sleeve heat exchanger 141 is abutted against the bottom plate of the outer casing 110; the first sleeve connector 1422 is located below the sleeve heat exchanger 141, one side of the first sleeve connector 1422 is connected to the lower end of the first sleeve support 1421, and the other side of the first sleeve connector 1422 extends away from the sleeve heat exchanger 141 and is detachably connected to the bottom plate.

[0095] Exemplarily, first casing support member 1421 includes at least one first casing support plate, which is positioned within the central hole of casing heat exchanger 141. A first side of the first casing support plate, distal from the central axis of casing heat exchanger 141, is connected to casing heat exchanger 141. The lower end of the first casing support plate abuts the base plate, leaving a mounting gap between casing heat exchanger 141 and the base plate. First casing connector 1422 includes at least one first casing connection plate, which corresponds one-to-one with the first casing support plate. Each first casing connection plate is positioned within the mounting gap, with one end of the first casing connection plate connected to the first casing support plate.

[0096] like Figure 11 and Figure 12 As shown, in some embodiments, a through hole 1523 is opened on the side of the press bracket 152, and the first sleeve connector 1422 is assembled in the through hole 1523. This can further reduce the installation space occupied, which is conducive to the miniaturization design of the air conditioner outdoor unit.

[0097] Optionally, a through hole 1523 is formed between the bottom of the left press support plate and the left press connecting plate.

[0098] Exemplarily, the first sleeve support plate of the first sleeve support member 1421, one end away from the sleeve heat exchanger 141, passes through the through-hole 1523 and is located above the left press support plate. The first sleeve support plate and the left press support plate can be detachably assembled on the bottom plate using screws.

[0099] like Figure 9 、 Figure 10 and Figure 13 As shown, in some embodiments, the sleeve support 142 further includes a second sleeve connector 1423 , which is arranged on a first side of the first sleeve support 1421 and spaced apart from the first sleeve connector 1422 around the central axis of the sleeve heat exchanger 141 .

[0100] In this embodiment, by providing the second sleeve connector 1423 , it can cooperate with the first sleeve connector 1422 to improve installation stability.

[0102] In this embodiment, by providing a bottom mounting plate 14231 and a second sleeve connecting plate 14232, the sleeve heat exchanger 141 is installed on the bottom plate. In addition, the inclined assembly design of the bottom mounting plate 14231 and the second sleeve connecting plate 14232, on the one hand, provides sufficient tool operation space to facilitate screw fixing; on the other hand, the inclined design is conducive to unloading force and facilitates disassembly.

When the shell and tube heat exchange assembly 140 needs to be disassembled, first remove the fixing screws between the left compressor connecting plate and the first shell and tube connecting plate, then remove the fixing screws between the second shell and tube connecting plate and the bottom mounting plate, and finally pull the shell and tube heat exchange assembly 140 out from left to right.

[0105] like Figure 13 As shown, optionally, the upper side of the bottom mounting plate 14231 has a first inclined assembly surface 14233, and the lower side of the second sleeve connecting plate 14232 has a second inclined assembly surface, and the second inclined assembly surface cooperates with the first inclined assembly surface 14233 to facilitate unloading and disassembly.

[0106] like Figure 13 As shown, optionally, the upper side of the second sleeve connecting plate 14232 has a third inclined assembly surface 14234, which is parallel to the second inclined assembly surface. The third inclined assembly surface 14234 can reduce the installation space in the vertical direction.

[0107] For example, the right end of bottom mounting plate 14231 is folded downward to form a first inclined plate. The upper side of the first inclined plate serves as a first inclined assembly surface 14233, and a threaded hole is provided on the first inclined plate. The right end of second sleeve connecting plate 14232 is folded downward to form a second inclined plate. The second inclined plate is parallel to the first inclined plate.

[0109] In this embodiment, by providing a second casing support 1424 spaced apart from the first casing support 1421 , the support stability of the casing heat exchanger 141 can be further improved.

[0110] Optionally, the second casing support 1424 includes a front casing support plate and a rear casing support plate; the front casing support plate is located in front of the central axis of the casing heat exchanger 141 , and the rear casing support plate is located in the rear of the central axis of the casing heat exchanger 141 .

[0111] A specific embodiment of the second aspect of the present invention provides an air conditioner, which includes the air conditioner outdoor unit of any of the above embodiments.

[0112] Since the air conditioner of this embodiment includes the air conditioner outdoor unit of any of the above embodiments, it has at least the above advantages, which will not be described in detail here.

[0113] Optionally, the air conditioner outdoor unit also includes a fan, a compressor, and an outdoor heat exchanger. The compressor is used to compress the refrigerant. The compressor is installed in the compressor chamber 113; the fan is installed in the fan chamber 112. The front panel of the outer housing 110 is provided with an outdoor air outlet. The outdoor heat exchanger is arranged behind the fan and compressor. The fan can draw air from the fan chamber 112 to the outdoor air outlet, and then discharge the air out of the outer housing 110 from the outdoor air outlet.

[0114] In one embodiment, the air conditioner further comprises an indoor unit; the indoor unit comprises an indoor heat exchanger; a refrigerant flow path is formed within the indoor heat exchanger; the refrigerant flow paths of the outdoor heat exchanger, the indoor heat exchanger, and the compressor are connected via a refrigerant pipeline to form a refrigerant circulation loop. In cooling mode, the high-temperature, high-pressure refrigerant discharged from the compressor enters the outdoor heat exchanger, then, after throttling, enters the refrigerant flow path of the indoor heat exchanger, and finally returns to the compressor, thereby achieving the purpose of cooling the room. In heating mode, the high-temperature, high-pressure refrigerant discharged from the compressor enters the refrigerant flow path of the indoor heat exchanger, then, after throttling, enters the outdoor heat exchanger, and finally returns to the compressor, thereby achieving the purpose of heating the room.

[0115] In one embodiment, a water flow channel is further formed in the indoor heat exchanger; water in the water flow channel and refrigerant in the refrigerant flow channel perform heat exchange in the indoor heat exchanger, so that the indoor heat exchanger discharges hot water or cold water.

[0116] Optionally, the air conditioner further includes a user terminal connected to both ends of the water flow channel to form a water circulation loop. Hot water or refrigerant discharged from the water flow channel flows to the user terminal, undergoes heat exchange again at the user terminal, and then returns to the water flow channel.

[0117] In some embodiments of the present invention, the air conditioner includes a heat pump system.

[0118] like Figure 14 As shown, in some embodiments of the present invention, the heat pump system includes a water-side heat exchanger 11, a first water pump module 12, a first valve body 13, a first reserved interface 14 and a second reserved interface 15; the water-side heat exchanger 11 is used to output hot water; the water inlet end of the first water pump module 12 is connected to the water outlet end of the water-side heat exchanger 11, and the water outlet end of the first water pump module 12 is connected to the water inlet end of the water-side heat exchanger 11 to form a water circulation loop; the first valve body 13 is arranged in the water circulation loop; the first valve body 13 has a conducting state and a cut-off state; the first reserved interface 14 is located at the water inlet end of the first valve body 13; the second reserved interface 15 is located at the water outlet end of the first valve body 13; the first reserved interface 14 and the second reserved interface 15 are used for detachable connection with the second water pump module 16.

[0119] In this embodiment, by reserving a first reserved interface 14 at the water inlet end of the first valve body 13 and a second reserved interface 15 at the water outlet end of the first valve body 13, when the first water pump module 12 is operating at its rated frequency and the actual temperature of the user terminal 19 still cannot reach the user's required temperature, the second water pump module 16 can be connected between the first reserved interface 14 and the second reserved interface 15, and at the same time, the first valve body 13 is switched from the on state to the off state, and the second water pump module 16 is started. At this time, the first water pump module 12 and the second water pump module 16 are connected in series and started at the same time, which can increase the water output and water pressure of the heat pump system and make the actual temperature of the user terminal 19 reach the user's required temperature. Such a design can expand the scope of application of the heat pump system and improve user experience, and solve the problem that the heat pump system in the prior art cannot dynamically adjust the heating efficiency according to actual demand due to the fixed frequency water pump, resulting in a poor user experience.

[0120] That is, in the heat pump system of this embodiment, a first reserved interface 14 and a second reserved interface 15 are reserved at both ends of the first valve body 13, allowing the user to decide whether to connect the second water pump module 16 based on their actual needs. When the first water pump module 12 can meet the user's needs, the first reserved interface 14 and the second reserved interface 15 can be closed, that is, the second water pump module 16 is not connected. When the first water pump module 12 is operating at its rated frequency, if the actual temperature of the user terminal 19 still cannot meet the user's needs, the user can connect the second water pump module 16 purchased separately to the first reserved interface 14 and the second reserved interface 15.

[0121] When the second water pump module 16 is connected to the first reserved interface 14 and the second reserved interface 15, the first valve body 13 switches from the on state to the off state. At this time, the first water pump module 12 and the second water pump module 16 are connected in series, and the water output of the heat pump system is the sum of the water outputs of the two water pump modules. When the second water pump module 16 is not connected to the first reserved interface 14 and the second reserved interface 15, the first valve body 13 switches from the off state back to the on state. The hot water discharged from the first water pump module 12 flows to the user end 19 after passing through the first valve body 13. The hot water no longer passes through the second water pump module 16. At this time, the water output of the heat pump system is the water output of the water outlet of the first water pump module 12.

[0122] Furthermore, the first valve body 13 may be a solenoid valve to facilitate automatic control.

[0123] like Figure 14As shown, in some embodiments, the heat pump system further includes a user terminal 19; the water inlet of the user terminal 19 is connected to the water outlet of the first valve body 13, and the water outlet of the user terminal 19 is connected to the water inlet of the water-side heat exchanger 11. Hot water flowing out of the water-side heat exchanger 11 enters the user terminal 19, where it undergoes heat exchange, thereby providing indoor heating. The cooled hot water discharged from the user terminal 19 returns to the water-side heat exchanger 11 and continues to exchange heat with the refrigerant.

[0124] Furthermore, the user terminal 19 includes an indoor heat exchanger.

[0125] like Figure 15 As shown, in some embodiments, the heat pump system further includes a second water pump module 16; the water inlet of the second water pump module 16 is connected to the first reserved interface 14; and the water outlet of the second water pump module 16 is connected to the second reserved interface 15. By adding the second water pump module 16, the applicable scenarios of the heat pump system can be improved and the application range can be expanded.

[0126] Optionally, the second water pump module 16 includes a second water pump body and a second water pump drive unit; the input end of the second water pump drive unit is electrically connected to the control module, and the output end of the second water pump drive unit is connected to the second water pump body. The second water pump drive unit is configured to control the second water pump body to stop or start according to control instructions issued by the control module.

[0127] Optionally, the second water pump drive unit and the second water pump body can be designed as an integrated system or as separate systems. For example, the second water pump drive unit and control module are located in the electrical control box, while the water inlet of the second water pump body is connected to the first reserved interface 14, and the water outlet of the second water pump body is connected to the second reserved interface 15. This design is characterized by the second water pump drive unit being designed separately from the second water pump body. For example, the second water pump drive unit is directly installed in the second water pump body, which is an integrated system.

[0128] Optionally, the second water pump drive unit includes a variable frequency drive board or a fixed frequency drive board.

[0129] like Figure 16 and Figure 17 As shown, in some embodiments, the heat pump system also includes a control module and a second switch module 17; the first output end of the control module is electrically connected to the first water pump module 12, for controlling the start and stop of the first water pump module 12; the second output end of the control module is electrically connected to the control end of the second switch module 17, for controlling the second switch module 17 to switch between a closed state and an open state; the second switch module 17 is also used to be electrically connected to the second water pump module 16; in the closed state, the second water pump module 16 is powered on and started; in the open state, the second water pump module 16 is powered off and stopped.

[0130] In this embodiment, by setting up a second switch module 17 electrically connected to the control module, and the second switch module 17 is also used to be electrically connected to the second water pump module 16, automatic control of powering on and off of the second water pump module 16 can be achieved, and automatic control of powering on and off of the second water pump module 16 can be achieved according to the actual operation conditions and actual needs of the system.

[0131] In addition, the first output end of the control module is electrically connected to the first water pump module 12 , so as to realize the control of starting and stopping the first water pump module 12 and realize the automatic control of the first water pump module 12 .

[0132] Optionally, the control module may be a microcontroller unit (MCU).

[0133] like Figure 17 As shown, the second switch module 17 optionally includes a relay. The control terminal of the relay is connected to the second output terminal of the control module, and the relay is disposed between the power supply 18 and the second water pump module 16. When the relay is closed, the relay, the power supply 18, and the second water pump module 16 form a current loop, powering on and starting the second water pump module 16. When the relay is open, the current loop is disconnected, and the second water pump module 16 loses power.

[0134] Optionally, the control module and the second switch module 17 can both be installed in the electrical control box. The second switch module 17 serves as a switch reserved for the second water pump module 16. When the second water pump module 16 is connected to the first reserved interface 14 and the second reserved interface 15, in order to also connect the second water pump module 16 to the control module of the heat pump system, the communication interface of the second water pump module 16 can be connected to the second switch module 17. In this way, the control module can be used to realize automatic control of the second water pump module 16.

[0135] like Figure 16 As shown, in some embodiments, the first water pump module 12 includes a first water pump drive unit and a first water pump body; the first output end of the control module is electrically connected to the input end of the first water pump drive unit; the first water pump body and the first water pump drive unit are arranged separately; the output end of the first water pump drive unit is electrically connected to the first water pump body, for driving the start and stop of the first water pump body.

[0136] The water pumps of existing heat pump systems are usually modular and integrated in design, that is, the water pump drive plate is integrated with the water pump body. In the design of the heat pump system, it is necessary to purchase a modularly designed water pump, which not only increases the material cost of the heat pump system, but also increases the control cost of the heat pump system.

[0137] In this embodiment, the first water pump body and the first water pump driving unit are arranged separately, which can not only reduce material costs and maintenance costs, but also reduce control costs.

[0138] Optionally, the control module and the first water pump drive unit may both be arranged in an electrical control box.

[0139] Optionally, the first water pump drive unit includes a variable frequency drive board. By providing the variable frequency drive board, the operating frequency of the first water pump body can be adjusted to adjust the water pressure and water volume, and the heating capacity of the heat pump system can be adjusted according to actual user needs, thereby alleviating energy waste.

[0140] In some embodiments, the heat pump system further includes an electrical control box; the control module, the second switch module 17 and the first water pump drive unit are all installed in the electrical control box.

[0141] like Figure 16 As shown, in some embodiments, the heat pump system further includes an information acquisition module; the information acquisition module is electrically connected to the input end of the control module; the information acquisition module is used to collect actual operating parameters of the heat pump system, and the actual operating parameters include at least one of the actual water outlet flow rate of the first water pump module 12, the outlet water temperature of the water side heat exchanger 11 and the inlet water temperature of the water side heat exchanger 11.

[0142] In this embodiment, actual operating parameters can be collected to determine the actual operating conditions of the system and provide a basis for the control module to adjust the first water pump module 12 and / or the second water pump module 16 to avoid blind adjustment.

[0143] Optionally, the information acquisition module includes various sensors. For example, the information acquisition module includes at least one of a flow sensor, an outlet water temperature sensor, and an inlet water temperature sensor. The flow sensor is disposed at the outlet of the first water pump body to detect the outlet water flow rate at the outlet of the first water pump body. The outlet water temperature sensor is disposed at the outlet of the water-side heat exchanger 11 to detect the outlet water temperature at the outlet of the water-side heat exchanger 11. The inlet water temperature sensor is disposed at the inlet of the water-side heat exchanger 11 to detect the inlet water temperature at the inlet of the water-side heat exchanger 11.

[0145] S100 , obtaining actual operating parameters of the heat pump system, where the actual operating parameters include at least one of the actual water outlet flow of the first water pump module 12 , the outlet water temperature of the water-side heat exchanger 11 , and the inlet water temperature of the water-side heat exchanger 11 .

[0146] Specifically, the information acquisition module is used to collect actual operating parameters of the heat pump system; the control module obtains the actual operating parameters from the information acquisition module.

[0147] Optionally, the information acquisition module includes a flow sensor disposed at the water outlet of the first water pump body for detecting the water flow rate at the water outlet of the first water pump body.

[0149] Optionally, the information acquisition module includes an inlet water temperature sensor disposed at the water inlet end of the water-side heat exchanger 11 for detecting the inlet water temperature at the water inlet end of the water-side heat exchanger 11. The control module obtains the actual inlet water temperature at the water inlet end of the water-side heat exchanger 11 from the inlet water temperature sensor.

[0150] It should be noted that the actual temperature of the user terminal 19 is related to the actual water outlet flow rate, the actual water outlet temperature and the actual water inlet temperature.

[0151] Optionally, the control module stores a corresponding relationship curve or corresponding relationship table between the actual temperature of the user terminal 19 and the actual water flow rate. In other words, the actual temperature of the user terminal 19 can be determined by the actual water flow rate, and thus it can be determined whether the actual temperature reaches the user's required temperature.

[0152] Optionally, the control module stores a corresponding relationship curve or corresponding relationship table between the actual temperature of the user terminal 19 and the actual water outlet temperature. In other words, the actual temperature of the user terminal 19 can be determined by the actual water outlet temperature, and thus it can be determined whether the actual temperature reaches the user's required temperature.

[0153] Optionally, the control module stores a corresponding relationship curve or corresponding relationship table between the actual temperature of the user terminal 19 and the actual water inlet temperature. In other words, the actual temperature of the user terminal 19 can be determined by the actual water outlet temperature, and thus it can be determined whether the actual temperature reaches the user's required temperature.

[0154] S200 , when the operating frequency of the first water pump module 12 reaches the frequency threshold and the actual operating parameter is still less than the required operating parameter, control the second switch module 17 to switch to a closed state to power on and start the second water pump module 16 .

[0155] In this embodiment, when the operating frequency of the first water pump module 12 reaches the frequency threshold and the actual operating parameters are still less than the required operating parameters, the control module controls the second switch module 17 to switch to the closed state, powering on the second water pump module 16. At this time, the first water pump module 12 and the second water pump module 16 are connected in series, increasing the actual operating parameters and allowing the actual temperature of the user terminal 19 to reach the user's required temperature. This design can expand the applicability of the heat pump system and enhance the user experience. It solves the problem that existing heat pump systems, which are equipped with fixed-frequency water pumps, cannot dynamically adjust the heating efficiency according to actual demand, resulting in a poor user experience.

[0156] It should be noted that the frequency threshold is not greater than the rated frequency of the first water pump module 12. Preferably, the frequency threshold refers to the rated frequency of the first water pump module 12.

[0157] Optionally, when the operating frequency of the first water pump module 12 reaches a frequency threshold and the actual water output at the water outlet of the first water pump body is still less than the required water output, the control module controls the second switch module 17 to switch from an open state to a closed state, at which point the second water pump module 16 is powered on and started. This design can increase the actual water output at the water outlet of the first water pump body, ensuring that the actual water output reaches at least the required water output, thereby ensuring that the actual temperature at the user terminal 19 reaches the user's required temperature.

[0158] In some embodiments, after obtaining the actual operating parameters of the heat pump system, the method further includes: If the operating frequency of the first water pump module 12 does not reach the frequency threshold, the operating frequency of the first water pump module 12 is adjusted based on actual operating parameters so that the actual operating parameters reach the desired operating parameters. Specifically, if the operating frequency of the first water pump module 12 does not reach the frequency threshold, the control module adjusts the operating frequency of the first water pump module 12 based on the relationship between the actual operating parameters and the desired operating parameters so that the actual operating parameters reach the desired operating parameters. This intelligent adjustment based on the actual operating status can improve the operating efficiency of the heat pump system and reduce energy consumption.

[0159] Optionally, if the operating frequency of the first water pump module 12 does not reach the frequency threshold, and the actual operating parameter is less than the required operating parameter, the control module controls the operating frequency of the first water pump module 12 to increase. If the actual operating parameter is greater than the required operating parameter, the control module controls the operating frequency of the first water pump module 12 to decrease. This ensures that the first water pump module 12 of the heat pump system can operate in an optimal state, improving the operating efficiency of the heat pump system and reducing energy consumption.

[0160] In some embodiments, before obtaining the actual operating parameters of the heat pump system, the method further includes: obtaining a real-time electrical signal of the first water pump module 12, the real-time electrical signal including a real-time voltage signal and / or a real-time current signal; the control method further includes: When the real-time electrical signal is not less than the electrical signal threshold, the first water pump module 12 is controlled to shut down. This design can achieve fault protection.

[0161] Optionally, when the real-time voltage signal is not less than the voltage signal threshold, the control module controls the first water pump module 12 to shut down to achieve fault protection.

[0162] Optionally, when the real-time current signal is not less than the current signal threshold, the control module controls the first water pump module 12 to shut down to achieve fault protection.

[0163] like Figure 19 As shown, in one embodiment of the present invention, the heat pump system control method of the present invention includes: S100, the control module obtains actual operating parameters of the heat pump system from the information acquisition module, and the control module also obtains the operating frequency of the first water pump module 12 from the first water pump module 12; S210, the control module determines whether the operating frequency of the first water pump module 12 reaches the frequency threshold; if so, proceed to S220; if not, proceed to S230; S220, the control module determines whether the actual operating parameter is less than the required operating parameter; if so, proceed to S250; if not, proceed to S260; S230, the control module determines whether the actual operating parameter is greater than the required operating parameter; if so, proceed to S270; if not, proceed to S260; S250 , the control module controls the second switch module 17 to switch to a closed state, so that the second water pump module 16 is powered on and started.

[0164] S260 , the control module controls the operating frequency of the first water pump module 12 to increase so that the actual operating parameters reach the required operating parameters.

[0165] S270 : The control module controls the operating frequency of the first water pump module 12 to decrease so that the actual operating parameters reach the required operating parameters.

[0166] In this embodiment, by dynamically connecting the second water pump module, the use range of the heat pump system can be expanded, and by adjusting the operating frequency of the first water pump module, energy consumption can be reduced and the operating efficiency of the heat pump can be improved.
