[0001] This utility model relates to the field of air conditioner technology, and in particular to an outdoor unit of an air conditioner and an air conditioner. Background Technology

[0002] Most outdoor units of air conditioners on the market are equipped with shell-and-tube heat exchangers. These exchangers are relatively large and require significant installation space. However, the space on the compressor side also needs to accommodate the compressor, piping, and other components, resulting in limited installation space and making maintenance difficult. Replacing the shell-and-tube heat exchanger in many existing heat pump air conditioners with such units is extremely cumbersome; some even require removing the compressor and its connected piping to install and remove the exchanger. This not only increases maintenance costs but also reduces the customer's product experience. Therefore, simplifying the installation and removal process of outdoor air conditioner units is a pressing issue for the industry. Utility Model Content

[0054] like Figure 7 As shown, the first aspect of this utility model provides an outdoor unit for an air conditioner. The outdoor unit includes an outdoor unit housing 110, a sleeve-and-tube heat exchange assembly 140, and a compressor assembly 150. The sleeve-and-tube heat exchange assembly 140 includes a sleeve-and-tube heat exchanger 141 and a sleeve-and-tube bracket 142; the sleeve-and-tube heat exchanger 141 is mounted on the outdoor unit housing 110 via the sleeve-and-tube bracket 142. The compressor assembly 150 includes a compressor 151 and a compressor bracket 152; a sleeve mounting cavity is formed within the compressor bracket 152, and the compressor 151 is mounted on the upper end of the compressor bracket 152, with the compressor 151 located outside the sleeve mounting cavity, and the sleeve-and-tube heat exchange assembly 140 located inside the sleeve mounting cavity; an inlet and outlet are provided on the side of the compressor bracket 152, communicating with the sleeve mounting cavity for the sleeve-and-tube heat exchange assembly 140 to enter and exit the sleeve mounting cavity.

[0055] In this embodiment, by setting the sleeve support 142, the sleeve heat exchanger 141 can be installed on the outer casing 110, achieving a modular design between the sleeve support 142 and the sleeve heat exchanger 141. The sleeve heat exchanger 141 can be disassembled and assembled by removing and installing the sleeve support 142. Similarly, by setting the compressor support 152, the compressor 151 is installed on the bottom plate of the outer casing 110 using the space between the compressors, achieving a modular design between the compressor 151 and the compressor support 152. The compressor 151 can be disassembled and assembled by removing and installing the compressor support 152. By installing the sleeve heat exchange assembly 140 inside the sleeve mounting cavity of the compressor support 152, and installing the compressor 151 on the upper end of the compressor support 152, located outside the sleeve mounting cavity, this vertical arrangement of the compressor 151 and the sleeve heat exchanger 141 fully utilizes the vertical space within the outer casing 110, avoiding the occupation of space in other directions of the outer casing 110. By opening an inlet and outlet on the side of the compressor bracket 152 that communicate with the sleeve mounting cavity, the entire sleeve heat exchange assembly 140 can enter and exit the sleeve mounting cavity through the inlet and outlet. When it is necessary to repair or disassemble the sleeve heat exchange assembly 140, it is not necessary to disassemble the compressor 151 and the pipe assembly connected to the compressor 151, thereby reducing maintenance costs and solving the defects of difficult disassembly and assembly of the outdoor unit of the air conditioner in the prior art.

[0056] In some embodiments, the outer casing 110 includes a side panel, 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 vertical direction, the upper end of the side panel of the outer casing 110 is connected to the top panel, the lower end of the side panel is connected to the bottom panel, and the side panel, the top panel, and the bottom panel enclose the outer casing 110.

[0057] Optionally, the side panels include a left side panel, a right side panel, a front side panel, and a rear side panel that are connected end to end.

[0058] Optionally, an installation cavity is formed inside the outer casing 110, and a partition plate 111 is installed in the installation cavity to divide 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 partition plate 111; the shell-and-tube heat exchange assembly 140 and the compressor assembly 150 are both located in the compressor cavity.

[0059] like Figure 8 and Figure 9 As shown, in some embodiments, the press bracket 152 includes a press support member 1524 and a press connector 1525; the press support member 1524 has a sleeve mounting cavity formed inside; the bottom of the press support member 1524 abuts against the bottom plate of the outer casing 110; a compressor 151 is mounted on the upper end of the press support member 1524; an inlet and outlet are provided 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.

[0060] In this embodiment, the compressor support 1524 directly supports the compressor 151 and abuts against the bottom plate of the outer casing 110 to form a stable vertical support. The compressor connector 1525 is independently fixed to the bottom plate and is laterally connected to the compressor support 1524 to provide lateral reinforcement and prevent vibration of the compressor 151 during operation from causing the support to shift or deform.

[0061] 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 the press connector 1525. This integrated design can not only reduce the number of parts and material costs, but also reduce stress concentration and improve the overall rigidity of the press bracket 152.

[0062] like Figure 8 and Figure 9 As shown, optionally, the press support 1524 includes multiple press support plates 15241 and press mounting plates 15242; the multiple press support plates 15241 are arranged around the central axis of the tube heat exchanger 141; the upper ends of the multiple press support members 1524 are all connected to the press mounting plates 15242 to form a tube mounting cavity; the lower ends of the press support plates 15241 abut against the bottom plate of the outer casing 110.

[0063] For example, the press support 1524 includes three press support plates 15241; the three press support plates 15241 are 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 this design, when it is necessary to disassemble or repair the shell-and-tube heat exchanger 141, it is only necessary to first remove the right side plate of the outer casing 110 to expose the inlet and outlet to the maintenance personnel, which facilitates the entry and exit of the shell-and-tube heat exchange assembly 140 into and out of the outer casing 110, simplifies the disassembly and assembly difficulty, and reduces maintenance costs.

[0064] Optionally, the press connector 1525 is located on the side of the press support 1524 away from the shell-and-tube heat exchanger 141. Compared to placing the press connector 1525 between the press support 1524 and the shell-and-tube heat exchanger 141, this design, placing 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.

[0065] 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.

[0066] For example, the press connector 1525 includes a left press connector plate; the left press connector plate is located to the left of the left press support plate 15241; the right side of the left press connector plate is connected to the left press support plate and is mounted on the bottom plate of the outer casing 110.

[0067] 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 also serve as a positioning function, facilitating the threaded assembly of the press connector 1525 and the base plate.

[0068] Optionally, the limiting structure 153 includes a limiting hole and a limiting protrusion; one of the limiting hole and the limiting protrusion is disposed in the press connector 1525, and the other is disposed in the base plate.

[0069] For example, the left press connecting plate of the press connector 1525 has a limiting hole, and a limiting protrusion is formed on the base plate. The limiting protrusion is inserted into the limiting hole. During installation, the limiting hole of the left press connecting plate can be matched with the limiting protrusion on the base plate first, which can play a pre-positioning role. Then, the left press connecting plate and the base plate can be threaded together with screws.

[0070] Optionally, the compressor connector 1525 may also include 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, and the front side of the front compressor connector plate is 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, and the rear side of the rear compressor connector plate is connected to the rear compressor support plate. This design avoids occupying space in the front-to-back direction of the outdoor unit casing 110, which is beneficial for the thinner design of the outdoor unit.

[0071] It should be noted that the shell-and-tube heat exchanger 141 is existing technology and will not be described in detail here. A valve seat is installed on the right side of the shell-and-tube heat exchanger 141; the inlet valve of the shell-and-tube heat exchanger 141 is installed on the valve seat.

[0072] In some embodiments, the shell-and-tube heat exchanger 141 is sleeved on the outside of the shell-and-tube support 142. In other words, the shell-and-tube support 142 is located inside the central hole of the shell-and-tube heat exchanger 141. This design can further reduce the space occupied during installation and is conducive to the miniaturization design of the outdoor unit of the air conditioner.

[0073] In some other embodiments, the sleeve support 142 is connected to the outside of the sleeve heat exchanger 141. In other words, the sleeve support 142 is located outside the central hole of the sleeve heat exchanger 141, and the collar heat exchanger is located between the sleeve heat exchanger 141 and the press support 152.

[0074] like Figure 9 As shown, in some embodiments, the sleeve support 142 includes a first sleeve support 1421 and a first sleeve connector 1422; the first sleeve support 1421 is connected to the sleeve heat exchanger 141 and is used to support the sleeve heat exchanger 141 on the bottom plate of the outer casing 110; the first sleeve connector 1422 is arranged on the first side of the first sleeve support 1421 away from the sleeve heat exchanger 141; the first sleeve connector 1422 is installed on the bottom plate of the outer casing 110 and is connected to the first sleeve support 1421.

[0075] In this embodiment, the first sleeve support 1421 is specifically used to fix the sleeve heat exchanger 141, ensuring its stable support. The first sleeve connector 1422 is independently fixed to the base plate and is laterally connected to the side of the first sleeve support 1421 to provide lateral reinforcement.

[0076] Optionally, the first sleeve support 1421 is located in the central hole of the sleeve heat exchanger 141 and is connected to the inner side of the sleeve heat exchanger 141. The lower end of the first sleeve heat exchanger 141 abuts 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.

[0077] For example, the first sleeve support 1421 includes at least one first sleeve support plate, which is located in the central hole of the sleeve heat exchanger 141. The first side of the first sleeve support plate away from the central axis of the sleeve heat exchanger 141 is connected to the sleeve heat exchanger 141, and the lower end of the first sleeve support plate abuts against the base plate, thus leaving an installation gap between the sleeve heat exchanger 141 and the base plate. The first sleeve connector 1422 includes at least one first sleeve connector plate; the first sleeve connector plate corresponds one-to-one with the first sleeve support plate, the first sleeve connector plate is located within the installation gap, and one end of the first sleeve connector plate is connected to the first sleeve support plate.

[0078] like Figure 11 and Figure 12 As shown, in some embodiments, the compressor bracket 152 has a through hole 1523 on its side, and the first sleeve connector 1422 is fitted into the through hole 1523. This can further reduce the space occupied during installation and is beneficial for the miniaturization design of the air conditioner outdoor unit.

[0079] Optionally, a through hole 1523 is formed between the bottom of the left press support plate and the left press connecting plate.

[0080] For example, the first sleeve support plate of the first sleeve support member 1421, with 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 to the base plate together using screws.

[0081] 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 the 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.

[0082] In this embodiment, by providing a second sleeve connector 1423, it can cooperate with the first sleeve connector 1422 to improve installation stability.

[0083] like Figure 13 As shown, optionally, the second sleeve connector 1423 includes a bottom mounting plate 14231 and a second sleeve connecting plate 14232; the bottom mounting plate 14231 is located below the first sleeve support 1421 and is connected to the base plate; the second sleeve connecting plate 14232 is arranged on the side of the first sleeve support 1421 away from the sleeve heat exchanger 141, and the second sleeve connecting plate 14232 and the first sleeve connector 1422 are spaced apart along the central axis of the sleeve heat exchanger 141; the second sleeve connecting plate 14231 is connected to the first sleeve support 1421 and is also assembled with the inclined surface of the bottom mounting plate 14231.

[0084] In this embodiment, by setting the bottom mounting plate 14231 and the second sleeve connecting plate 14232, the sleeve heat exchanger 141 is installed on the base plate. In addition, the inclined assembly design of the bottom mounting plate 14231 and the second sleeve connecting plate 14232 serves two purposes: firstly, to provide sufficient tool operating space for easy screw fixing; secondly, the inclined design facilitates stress relief and easy disassembly.

[0085] Optionally, the sleeve connection plate is arranged at the inlet and outlet, further improving assembly and disassembly efficiency.

[0086] Optionally, the inlet and outlet are located on the right side of the shell-and-tube heat exchanger 141, and the second shell-and-tube connector 1423 is also located on the right side of the shell-and-tube heat exchanger 141; the first shell-and-tube connector 1422 is located on the left side of the shell-and-tube heat exchanger 141. When it is necessary to disassemble the shell-and-tube heat exchanger assembly 140, 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 entire shell-and-tube heat exchanger assembly 140 out from left to right to disassemble the shell-and-tube heat exchanger assembly 140.

[0087] like Figure 13 As shown, optionally, the upper side of the bottom mounting plate 14231 has a first inclined mounting surface 14233, and the lower side of the second sleeve connecting plate 14232 has a second inclined mounting surface. The second inclined mounting surface and the first inclined mounting surface 14233 cooperate with each other to facilitate stress relief and disassembly.

[0088] like Figure 7 As shown, optionally, the upper side of the second sleeve connecting plate 14232 has a third inclined mounting surface 14234, which is parallel to the second inclined mounting surface. The third inclined mounting surface 14234 can reduce the installation space in the vertical direction.

[0089] For example, the right end of the bottom mounting plate 14231 is folded downward to form a first inclined plate. The upper side of the first inclined plate is a first inclined mounting surface 14233, and a threaded hole is provided on the first inclined plate. The right end of the 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. The upper side of the second inclined plate is a second inclined mounting surface, and the lower side of the second inclined plate is a third inclined mounting surface 14234. A threaded hole is provided on the second inclined plate. The threaded hole on the first inclined plate corresponds to the threaded hole on the second inclined plate. A screw is threaded into the threaded hole to connect the bottom mounting plate 14231 and the second sleeve connecting plate 14232.

[0090] like Figure 9 and Figure 10 As shown, in some embodiments, the sleeve support 142 further includes a second sleeve support 1424; the second sleeve support 1424 is connected to the sleeve heat exchanger 141; the second sleeve support 1424 and the first sleeve support 1421 are arranged at intervals around the central axis of the sleeve heat exchanger 141, and the lower end of the second sleeve support 1424 abuts against the base plate.

[0091] In this embodiment, by providing a second sleeve support 1424 spaced apart from the first sleeve support 1421, the support stability of the sleeve heat exchanger 141 can be further improved.

[0092] Optionally, the second sleeve support 1424 includes a front sleeve support plate and a rear sleeve support plate; the front sleeve support plate is located on the front side of the central axis of the sleeve heat exchanger 141, and the rear sleeve support plate is located on the rear side of the central axis of the sleeve heat exchanger 141.

[0093] like Figures 1 to 6As shown, in some embodiments of this utility model, the outdoor unit of the air conditioner includes an outdoor unit housing 110, an electrical control box 120, and an air guiding mechanism 130. A fan cavity 112 is formed inside the outdoor unit housing 110; a first air inlet 101 is provided on the outdoor unit housing 110; the electrical control box 120 is located on one side of the fan cavity 112; the air guiding mechanism 130 includes a first air guiding assembly 131; the first air guiding assembly 131 is connected to the electrical control box 120; a first air guiding channel is formed inside the first air guiding assembly 131; an electrically controlled radiator 127 of the electrical control box 120 is installed inside the first air guiding channel; the air inlet of the first air guiding channel communicates with the first air inlet 101; and the air outlet of the first air guiding channel communicates with the fan cavity 112.

[0094] In this embodiment, a first air guide assembly 131 with a first air guide channel formed inside 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 cavity 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 electrically controlled radiator 127, where the cold air exchanges heat with the radiator 127, improving its heat dissipation capacity. The cooled airflow can then be actively drawn out by the fan installed in the fan cavity 112, forming an overall "air inlet-heat dissipation-exhaust" path, i.e., the first air duct. This not only improves the heat exchange efficiency of the electrically controlled radiator 127 in the electrical control box 120 and enhances its heat dissipation capacity, solving the problem of limited heat dissipation capacity of the electrical control box 120 in existing air conditioning outdoor units, but also reduces energy loss caused by airflow turbulence.

[0095] In addition, without changing the overall structure of the outdoor unit of the air conditioner, the available installation space inside the unit can be used to add an air guide mechanism 130 to improve the heat dissipation capacity of the electrical control box 120.

[0096] Optionally, the outer casing 110 includes side panels, a top panel, and a bottom panel; the top panel and bottom panel of the outer casing 110 are arranged at intervals in the vertical direction, the upper end of the side panel of the outer casing 110 is connected to the top panel, the lower end of the side panel is connected to the bottom panel, and the side panels, top panel, and bottom panel enclose the outer casing 110.

[0097] Optionally, the side panels include a left side panel, a right side panel, a front side panel, and a rear side panel that are connected end to end.

[0098] Optionally, the electrical control heat sink 127 of the electrical control box 120 is installed on the outside of the electrical control box 120.

[0099] Optionally, there may be multiple first air inlets 101, which are arranged at intervals along the vertical direction.

[0100] Optionally, the shape of the first air inlet 101 can be circular, elliptical, or polygonal. In specific embodiments of this utility model, the shape of the first air inlet 101 is not limited.

[0101] like Figure 2 As shown, optionally, a compressor cavity 113 is also formed inside 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 communicates with 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, making full use of the vertical space of the outer casing 110, avoiding additional occupation of the fan cavity 112 or other key areas, making the overall layout more compact, and achieving full utilization of 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. However, compared with the electrical control module board 125 and the main control board 126 of the electrical control box 120, the temperature of the compressor cavity 113 is usually lower. Therefore, when an opening is formed at the lower end of the electrical control box 120 so that the inner cavity of the electrical control box 120 is connected to the compressor cavity 113, the opening allows the cold air in the compressor cavity 113 to rise naturally into the inner cavity of the electrical control box 120, forming a passive cooling airflow and improving the heat dissipation effect of the electrical control box 120.

[0102] 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 internal space. 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 casing 110, making the entire unit more compact.

[0103] like Figure 2 As shown, optionally, the outdoor unit of the air conditioner also includes a partition 111; an installation cavity is formed inside the outdoor unit housing 110; the partition 111 is installed in the installation cavity to divide the installation cavity into a fan cavity 112 and a compressor cavity 113; the compressor cavity 113 is located on the right side 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 plate of the electrical control box 120 is connected to the upper end of the partition 111; the first air guide assembly 131 is installed on the outer side of the back plate of the electrical control box 120. A first air inlet 101 is opened on the right side plate of the outdoor unit housing 110; the air inlet of the first air guide channel faces the first air inlet 101.

[0104] In one embodiment, the outer casing 110 has a second air inlet 102, which communicates with the compressor cavity 113; the electrical control box 120 has a second air outlet 121 on the side near the fan cavity 112, which also communicates with 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's pipe assembly, absorbing the heat generated by the high-temperature pipes to prevent the electrical control box 120 from being overheated. The air, after exchanging heat with the high-temperature pipes, enters the electrical control box 120 through the bottom opening and then enters the fan cavity 112 through the second air outlet 121. It is then discharged under the suction of the fan, thus forming a second air duct. The first and second air ducts work together to further improve the heat dissipation effect of the electrical control box 120.

[0105] Optionally, there may be multiple second air inlets 102, which are arranged at intervals along the vertical direction.

[0106] Optionally, the shape of the second air inlet 102 can be circular, elliptical, or polygonal. In specific embodiments of this utility model, the shape of the second air inlet 102 is not limited.

[0107] Optionally, a second air inlet 102 is provided on the right side panel of the outer casing 110. The second air inlet 102 is located below the first air inlet 101, which is connected to the first air guide channel. The second air inlet 102 is connected to the compressor cavity 113. A second air outlet 121 is provided on the left side panel of the electrical control box 120 (i.e., the side panel near the fan cavity 112). The second air outlet 121 is used to connect the fan cavity 112 to the inner cavity of the electrical control box 120.

[0108] 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 is connected to the first air guide channel. Cold air from the outside enters the compressor cavity 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 guide channel from the third air outlet 122. In conjunction with the second air guide channel, multi-directional heat dissipation of the electrical control box 120 can be achieved.

[0109] Optionally, the left side panel of the electrical control box 120 is provided with a second air outlet 121, and the rear side panel of the electrical control box 120 is provided with a third air outlet 122. The heat exchange air entering the electrical control box 120 from the opening may partially enter the fan chamber 112 from the second air outlet 121, and may partially enter the first air guide channel from the third air outlet 122, so that the heat exchange air can be discharged from the electrical control box 120 from different directions, thereby achieving heat dissipation from different directions of the electrical control box 120 and further improving the heat dissipation effect of the electrical control box 120.

[0110] Optionally, the back panel of the electrical control box 120 is also provided with a fourth air outlet 123; the fourth air outlet 123 and the third air outlet 122 are arranged at intervals 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 work with the third air outlet 122 to achieve heat dissipation of the upper and lower spaces of the electrical control box 120. External cold air enters the compressor cavity 113 through the second air inlet 102. The cold air passes through the pipe assembly components inside the compressor to cool the high-temperature pipes. The heat-exchanged air enters the electrical control box 120 through the bottom opening. Some of the heat-exchanged air entering the electrical control box 120 may pass through the fourth air outlet 123 to carry away the heat below the electrical control box 120; some may pass through the third air outlet 122 to carry away the heat above the electrical control box 120. Air discharged from the third air outlet 122 and the fourth air outlet 123 both enter the first air guide channel, and finally enter the fan cavity 112. Under the action of the fan, the air is discharged from the outer casing 110, thus forming the third air duct. In this embodiment, the three air ducts can achieve all-round heat dissipation for the electrical control box 120. On the one hand, they absorb the heat generated by the electrical control box 120 itself, and on the other hand, they absorb the heat generated by the high-temperature pipeline in the compressor cavity 113. This greatly reduces the temperature rise of the components on the electrical control box 120 and extends the service life of the components.

[0111] like Figure 4 and Figure 5 As shown, in one embodiment, the air guiding mechanism 130 further includes a second air guiding component 132; the second air guiding component 132 has a second air guiding channel formed inside, the air inlet of the second air guiding channel is connected to the air outlet of the first air guiding channel, and the air outlet of the second air guiding channel is connected to the fan cavity 112; the second air guiding component 132 is installed on the outer side of the side plate of the electrical control box 120 near the fan cavity 112, and is connected to the first air guiding component 131. This design can prevent hot air generated by the heat exchanger of the whole machine from entering the air guiding channel during high-temperature cooling, thus affecting the heat dissipation efficiency of the electrical control box 120.

[0112] Specifically, the first air guide assembly 131 is installed 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 outdoor unit housing 110, and the other end extends to the left to the left edge of the back panel of the electrical control box 120. The second air guide assembly 132 is installed 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, and the other end of the second air guide assembly 132 extends forward, splicing with the first air guide assembly 131 to form an air guide mechanism 130 with an "L" shaped cross-section. The outdoor heat exchanger of the outdoor unit of the air conditioner is usually installed on the rear side of the fan cavity 112 and the compressor cavity 113. By setting 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.

[0113] Optionally, the first air guide assembly 131 includes a first air guide shroud; the first air guide shroud is disposed on the outer side of the back panel of the electrical control box 120, and together with the back panel forms a first air guide channel. By forming a first air guide channel by the first air guide shroud and the back panel of the electrical control box 120, material costs can be reduced.

[0114] Optionally, the second air guide assembly 132 includes a second air guide shroud; the second air guide shroud is disposed on the outer side of the left side plate of the electrical control box 120 and forms a second air guide channel with the left side plate of the electrical control box 120; the rear end of the second air guide shroud is also connected to a first air guide shroud so that the first air guide channel communicates with the second air guide channel.

[0115] like Figures 3 to 6 As shown, in one embodiment, the electrical control box 120 includes an electrical control box 120 body, an electrical control module board 125, and an electrical control main control board 126. The electrical control box 120 body is located on one side of the fan cavity 112. The first air guide assembly 131 is connected to the electrical control box 120 body. The electrical control module board 125 and the electrical control main control board 126 are both located inside the electrical control box 120 body and are respectively installed on two different side panels of the electrical control box 120 body. In this embodiment, installing the electrical control module board 125 and the electrical control main control board 126 on two different side panels of the electrical control box 120 body can not only avoid the concentration of high-heat-generating components and reduce the thermal coupling effect, but also reduce electromagnetic interference and thermal interference. The first air guide assembly 131 can provide directional heat dissipation for heat sources on different side panels. The first air guide assembly 131 is arranged on the outside of the electrical control box 120 body, without occupying the internal space of the electrical control box 120 body, ensuring neat wiring inside the box.

[0116] It should be noted that the electronic control module board 125 is mainly responsible for power execution, while the electronic control main control board 126 is mainly responsible for intelligent control.

This front-to-back layout can reduce the overall size of the outdoor unit of the air conditioner in the vertical direction; at the same time, the first air guide and the electrical control radiator 127 installed on the outer side of the back panel of the main body of the electrical control box 120 can achieve timely heat dissipation of the electrical control module board 125.

[0118] Optionally, a third air outlet 122 is provided on the upper side of the back panel of the electrical control box 120 body, a fourth air outlet 123 is provided on the lower side of the back panel of the electrical control box 120 body, and a second air outlet 121 is provided on the left side panel of the electrical control box 120 body.

[0119] Optionally, there may be multiple second air outlets 121, which are arranged at intervals along the vertical direction.

In cooling mode, the high-temperature, high-pressure refrigerant discharged from the compressor enters the outdoor heat exchanger, then undergoes throttling and other processes to enter the refrigerant flow channel of the indoor heat exchanger, and finally returns to the compressor, achieving the purpose of cooling the indoor unit. In heating mode, the high-temperature, high-pressure refrigerant discharged from the compressor enters the refrigerant flow channel of the indoor heat exchanger, then undergoes throttling and other processes to enter the outdoor heat exchanger, and finally returns to the compressor, achieving the purpose of heating the indoor unit.

[0129] In one embodiment, a water channel is also formed inside the indoor heat exchanger; the water in the water channel and the refrigerant in the refrigerant channel exchange heat and cold in the indoor heat exchanger, so that the indoor heat exchanger discharges hot or cold water.
