[0056] The outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0057] As Figure 1 and Figure 2 shown, the outdoor unit 100 according to an embodiment of the present invention includes a housing 1, a heat exchanger 2, a compressor 5 and an electric control assembly.

[0058] Specifically, as Figure 1 and Figure 2 shown, a middle partition 17 is provided inside the housing 1, and the middle partition 17 divides the space inside the housing 1 into a blower chamber and a compressor chamber 16 which are spaced apart in the left-right direction (the left-right direction shown as Figure 1 ). The blower is arranged in the blower chamber, and the compressor 5 is arranged in the compressor chamber 16. Among them, the housing 1 includes a chassis 11, a back plate, side plates on the left and right sides, a front panel 12 and a top plate 14. The back plate, side plates and front panel 12 are arranged on the chassis 11 and connected to the chassis 11, and the top plate 14 is arranged above the back plate, side plates and front panel 12 and connected to the upper ends of the back plate, side plates and front panel 12.

[0059] As Figure 1 and Figure 2As shown, the heat exchanger 2, the compressor 5, and the electronic control component (not shown in the figure) are disposed within the compressor chamber 16. Among them, the heat exchanger 2 can be a shell-and-tube heat exchanger. The shell-and-tube heat exchanger is wound. The shell-and-tube heat exchanger includes an inner tube and an outer tube sleeved outside the inner tube. The outer tube can be a steel part, and the inner tube can be a copper part. Water can flow inside the inner tube, and a cavity between the inner tube and the outer tube can be for refrigerant flow to achieve heat exchange between the refrigerant and water.

[0060] Further, the outer diameter of the outer tube can be 35 mm. As Figure 13 shown, the projection of the shell-and-tube heat exchanger on the chassis 11 is generally quadrilateral, and the radius of the center line of the bending area between adjacent two sides of each layer of the outer tube on the shell-and-tube heat exchanger can be 75 mm.

[0061] As Figure 1 and Figure 2 shown, in the up-and-down direction, the electronic control component, the compressor 5, and the heat exchanger 2 are arranged in sequence. It can be understood that the compressor 5 is installed in the middle of the compressor chamber 16, the heat exchanger 2 is installed below the compressor 5, for example, it can be installed on the chassis 11, and the electronic control component is disposed above the compressor 5. Both the electronic control component and the compressor 5 have electrical components, so that the heat exchanger 2, the compressor 5, and the electronic control component are arranged in the up-and-down direction, realizing separation of water and electricity and improving the safety of the outdoor unit 100.

[0062] In addition, the heat exchanger 2 is disposed below the compressor 5, which not only facilitates the assembly and placement of the heat exchanger 2, etc., but also can reduce the space occupied by the compressor 5 and the heat exchanger 2 in the horizontal direction, facilitating the reasonable layout between the compressor 5 and the heat exchanger 2, and thus being beneficial to reducing the volume of the outdoor unit 100.

[0063] For the outdoor unit 100 according to the embodiment of the present invention, by disposing the heat exchanger 2, the compressor 5, and the electronic control component within the compressor chamber 16, and in the up-and-down direction, the electronic control component, the compressor 5, and the heat exchanger 2 are arranged in sequence, it can separate the heat exchanger 2 from the electrical components on the compressor 5 and the electronic control component, realize separation of water and electricity, ensure the safety and reliability of the operation of the outdoor unit 100, and at the same time make the layout of the compressor 5 and the heat exchanger 2 more reasonable and compact, reduce the space occupied by the compressor 5 and the heat exchanger 2 in the horizontal direction, and be beneficial to reducing the volume of the outdoor unit 100.

[0064] In some embodiments of the present invention, as Figures 1-3As shown, the outdoor unit 100 further includes a support bracket 3 and a support plate 4. The support bracket 3 is disposed in the compressor chamber 16 and its lower end is connected to the chassis 11 of the housing 1. The support bracket 3 is spaced apart from the heat exchanger 2. The support plate 4 is located above the heat exchanger 2 and is connected to the upper end of the support bracket 3 and the middle partition plate 17. The compressor 5 is disposed above the support plate 4 and is connected to the support plate 4. The compressor 5 is supported above the heat exchanger 2 by the support bracket 3 and the support plate 4, which facilitates the fixing of the compressor 5. When overhauling the heat exchanger 2, after removing the top cover, the front panel 12 and the side panel on the compressor 5 side, the compressor 5 does not need to be disassembled, which can simplify the maintenance process.

[0065] Among them, as Figure 1 shown, when the front panel 12 includes a first panel located on the front side of the blower chamber and a second panel located on the front side of the compressor chamber 16, when overhauling the heat exchanger 2, only the second panel located on the front side of the compressor chamber 16 needs to be disassembled.

[0066] Furthermore, the compressor 5 and the support plate 4 are fixedly installed through fasteners such as bolts to complete the central installation of the compressor 5 in the up and down direction.

[0067] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the support bracket 3 includes a front bracket 31 and a rear bracket 32. The front bracket 31 is located on the front side of the heat exchanger 2 and its lower end is connected to the chassis 11, and the upper end is connected to the support plate 4. The rear bracket 32 is located on the rear side of the heat exchanger 2 and its lower end is connected to the chassis 11, and the upper end is connected to the support plate 4. The front bracket 31 and the rear bracket 32 respectively support the support plate 4 at both ends of the support plate 4 in the front and rear directions, improving the reliability of the fixing of the support plate 4, thereby improving the reliability of the fixing of the compressor 5 and ensuring the reliability of the operation of the outdoor unit 100.

[0068] Furthermore, when overhauling the heat exchanger 2, after removing the front panel 12, the front bracket 31 can be disassembled so that the heat exchanger 2 is exposed for overhauling the heat exchanger 2, and the rear bracket 32 does not need to be disassembled, reducing the workload of maintenance.

[0069] Optionally, the lower ends of both the front bracket 31 and the rear bracket 32 are fixed to the chassis 11 through fasteners such as screws, and the upper ends can also be connected to the support plate 4 through fasteners such as screws.

[0070] In some embodiments of the present invention, as Figure 4As shown, at least one of the front bracket 31 and the rear bracket 32 includes a support plate 311 and a flanging 312 provided at the outer edge of the support plate 311. The flanging 312 extends along the length direction of the outer edge of the support plate 311. At least one of the connection between the support plate 311 and the flanging 312 and the support plate 311 is provided with a reinforcing rib 313. Thereby, the structural strength of the front bracket 31 and the rear bracket 32 can be enhanced, thus improving the reliability of the support for the pallet 4, further improving the reliability of the support for the compressor 5, and enhancing the reliability of the operation of the outdoor unit 100.

[0071] For example, in Figure 4 the example shown, the front bracket 31 includes a support plate 311 and a flanging 312 provided at the outer edge of the support plate 311. The flanging 312 bends and extends toward the heat exchanger 2 side. Among them, flangings 312 are provided at both the upper and lower ends of the support plate 311 and on both sides in the left-right direction of the outdoor unit 100. The support plate 311 is provided with a reinforcing rib 313 extending in the up-down direction. The reinforcing rib 313 is a groove structure recessed away from the heat exchanger 2 side. Three reinforcing ribs 313 are provided on the support plate 311 at intervals in the left-right direction of the outdoor unit 100. In addition, triangular reinforcing ribs 313 are provided at the connection between the upper and lower ends of the support plate 311 and the flanging 312. Thereby, the strength of the front bracket 31 can be enhanced, and the flangings 312 located on both sides of the support plate 311 in the left-right direction of the outdoor unit 100 can improve the stiffness of the front bracket 31. The rear bracket 32 includes a support plate 311 and flangings 312 provided at the upper and lower ends of the support plate 311. The support plate 311 is provided with a reinforcing rib 313 extending in the up-down direction.

[0072] In some embodiments of the present invention, as Figures 4-6 shown, at least one of the lower ends of the front bracket 31 and the rear bracket 32 is provided with a positioning insert piece 314 extending downward. The chassis 11 is provided with an insert hole cooperating with the positioning insert piece 314. Thus, when installing the front bracket 31 or the rear bracket 32, the positioning insert piece 314 can be inserted into the insert hole and then the front bracket 31 and the rear bracket 32 can be connected to the chassis 11 through fasteners. The cooperation between the positioning insert piece 314 and the insert hole can play a role of pre-positioning, so that there is no need to align holes when connecting the front bracket 31 and the chassis 11 and when connecting the rear bracket 32 and the chassis 11, improving the assembly efficiency.

[0073] For example, in Figures 4-6 the example shown, both the lower ends of the front bracket 31 and the rear bracket 32 have positioning insert pieces 314 that bend downward and extend. The chassis 11 has insert holes cooperating with the positioning insert pieces 314 on the front bracket 31 and the rear bracket 32, facilitating the positioning of the front bracket 31 and the chassis 11 and the rear bracket 32 and the chassis 11, and thus facilitating the installation of the front bracket 31 and the chassis 11.

[0074] In some embodiments of the present invention, as Figure 4And Figure 7 As shown in Figure 7 , at least one of the front bracket 31 and the rear bracket 32 is provided with a positioning catch 315, and the support plate 4 is provided with a positioning hole 41 that cooperates with the positioning catch 315. Thus, when installing the front bracket 31 and the support plate 4 or the rear bracket 32 and the support plate 4, the positioning catch 315 can be inserted into the positioning hole 41, and then the support plate 4 can be connected to the front bracket 31 and the rear bracket 32 through fasteners. The cooperation between the positioning catch 315 and the positioning hole 41 can play a role in pre-positioning, so that there is no need to align the holes when connecting the front bracket 31 and the support plate 4 and when connecting the rear bracket 32 and the support plate 4, improving the assembly efficiency.

[0075] For example, in Figure 4 and Figure 7 In the example shown in Figure 7 , the upper ends of both the front bracket 31 and the rear bracket 32 have positioning catches 315 extending upward, and the support plate 4 has positioning holes 41 that cooperate with the positioning catches 315 on the front bracket 31 and the rear bracket 32, facilitating the positioning of the front bracket 31 and the support plate 4 and the rear bracket 32 and the support plate 4, and thus facilitating the installation of the front bracket 31 and the support plate 4 and the rear bracket 32 and the support plate 4.

[0076] In some embodiments of the present invention, as Figure 2 shown in Figure 2 , the support plate 4 is snap-connected and / or connected by fasteners to the middle partition 17. It can be understood that the support plate 4 and the middle partition 17 can be only snap-connected, or the support plate 4 and the middle partition 17 can be only connected by fasteners, or the support plate 4 and the middle partition 17 can be both snap-connected and connected by fasteners, which can not only simplify the connection method between the support plate 4 and the middle partition 17, but also improve the reliability of the connection between the support plate 4 and the middle partition 17, ensuring the strength of the support plate 4 installation and the reliability of the fixation.

[0077] When overhauling the heat exchanger 2, after removing the top cover, the front panel 12 and the side plate on the compressor 5 side, without disassembling the compressor 5, only the support bracket 3 needs to be removed, facilitating the disassembly and repair of the heat exchanger 2. Since the support plate 4 is connected to the middle partition 17, the compressor 5 can still be reliably supported after removing the support bracket 3, reducing the workload of maintenance and facilitating the overhaul of the heat exchanger 2.

[0078] For example, in Figure 2 In the example shown in Figure 2 , the support plate 4 is both snap-connected by a buckle and installed and fixed by fasteners such as screws, improving the convenience of positioning the support plate 4 during installation and the reliability of the connection between the support plate 4 and the middle partition 17.

[0079] In some embodiments of the present invention, as Figures 8-10As shown, the heat exchanger 2 is a double-pipe heat exchanger. The outdoor unit 100 further includes a gas-liquid separator 7, and the gas-liquid separator 7 is disposed in the internal space formed by surrounding the double-pipe heat exchanger. Thus, the hollow space inside the double-pipe heat exchanger 2 can be fully utilized, further saving the space inside the housing 1, improving the utilization rate of the structural space, facilitating the overall structural layout of the machine, being beneficial to reducing the overall size of the machine, lowering the cost and being more convenient for installation.

[0080] Furthermore, as Figure 9 shown, a first support 21 is provided at the rear end of the heat exchanger 2. The lower end of the first support 21 is connected to the chassis 11. Thus, the connection between the heat exchanger 2 and the chassis 11 can be realized, and the fixation of the heat exchanger 2 can be achieved. At the same time, a positioning support 71 is provided on the gas-liquid separator 7, and the positioning support 71 is connected to the upper end of the first support 21. Thus, the connection between the gas-liquid separator 7 and the heat exchanger 2 can be realized, and the fixation of the gas-liquid separator 7 can be achieved, facilitating the welding connection of the pipelines. At the same time, the gas-liquid separator 7 and the heat exchanger 2 can be formed into a component, making the internal structure of the outdoor unit 100 modular. During assembly, the gas-liquid separator 7 and the heat exchanger 2 can be pre-assembled, improving the production efficiency of the general assembly.

[0081] Among them, the gas-liquid separator 7 and the heat exchanger 2 are arranged at intervals.

[0082] Optionally, the first support 21 and the chassis 11 can be connected by fasteners, the first support 21 is welded to the heat exchanger 2, and the positioning support 71 is welded to the gas-liquid separator 7.

[0083] Furthermore, as Figures 9-12 shown, a hanging hole 213 is provided on the first support 21, and a hook 72 cooperating with the hanging hole 213 is provided on the positioning support 71. Thus, the positioning of the gas-liquid separator 7 can be realized by hanging the hook 72 on the positioning support 71 in the hanging hole 213 on the first support 21, facilitating the connection between the first support 21 and the positioning support 71.

[0084] In some embodiments of the present invention, as Figures 10-12 shown, the first support 21 includes a first vertical plate 211 and a first horizontal plate 212 connected to the upper end of the first vertical plate 211. The positioning support 71 includes a second vertical plate 711 and a second horizontal plate 712 connected to the upper end of the second vertical plate 711. The hanging hole 213 includes a first hanging hole 2131 provided on the first vertical plate 211. The hook 72 includes a first hook 721 provided on the second vertical plate 711, and the first hook 721 cooperates with the first hanging hole 2131. Thus, the reliability of the positioning between the first support 21 and the positioning support 71 can be improved. Among them, the cooperation between the first hook 721 and the first hanging hole 2131 can also limit the movement of the gas-liquid separator 7 in the left-right direction of the outdoor unit 100.

[0085] In some embodiments of the present invention, as Figures 10-12 shown, the first bracket 21 includes a first vertical plate 211 and a first horizontal plate 212 connected to the upper end of the first vertical plate 211. The positioning bracket 71 includes a second vertical plate 711 and a second horizontal plate 712 connected to the upper end of the second vertical plate 711. The hanging hole 213 includes a second hanging hole 2132 provided on the first horizontal plate 212. The hook 72 includes a second hook 722 provided on the second horizontal plate 712. The second hook 722 cooperates with the second hanging hole 2132. Thereby, the reliability of positioning between the first bracket 21 and the positioning bracket 71 can be improved. Among them, the cooperation between the second hook 722 and the second hanging hole 2132 can also limit the movement of the gas-liquid separator 7 in the left-right direction of the outdoor unit 100.

[0086] Furthermore, as Figure 9 and Figure 13 shown, the first horizontal plate 212 and the second horizontal plate 712 are connected by fasteners. The fasteners are passed through the first horizontal plate 212 and the second horizontal plate 712, which is convenient for the installation and connection of the fasteners and can improve the assembly efficiency.

[0087] In some embodiments of the present invention, as Figure 9 shown, the upper end of the first bracket 21 extends beyond the heat exchanger 2, and the connection point between the positioning bracket 71 and the first bracket 21 is located above the heat exchanger 2. Thereby, it is convenient for the operator to connect the positioning bracket 71 and the first bracket 21, improving the assembly efficiency between the first bracket 21 and the positioning bracket 71, and thus improving the assembly efficiency between the heat exchanger 2 and the gas-liquid separator 7.

[0088] In some embodiments of the present invention, as Figure 14 shown, the lower end of the first bracket 21 has a first insertion piece 214 extending downward, and the chassis 11 has a first positioning hole cooperating with the first insertion piece 214. Thus, when assembling the heat exchanger 2, the first insertion piece 214 can be inserted into the first positioning hole and then the first bracket 21 can be connected to the chassis 11 by fasteners, realizing the connection between the heat exchanger 2 and the chassis 11, and thus realizing the fixation of the heat exchanger 2. Among them, the cooperation between the first insertion piece 214 and the first positioning hole can play a role of pre-positioning, so that there is no need to align holes when connecting the first bracket 21 and the chassis 11, improving the assembly efficiency.

[0089] In some embodiments of the present invention, as Figure 3 and Figure 7 shown, there is a water receiving tank 42 above the tray 4, and a drain port 43 is provided on the bottom wall of the water receiving tank 42. The tray 4 can be formed into a water receiving tray structure. The water receiving tank 42 can be used to receive the condensed water dripping from the upper pipeline of the compressor 5. The condensed water can be centrally discharged through the drain port 43, avoiding the random flow of the condensed water dripping onto the tray 4 and preventing the condensed water from dripping onto the components below the tray 4 and damaging the components below the tray 4.

[0090] Further, as shown in Figure 3 and Figure 7 , a diversion groove 44 is provided on the bottom wall of the water receiving tank 42, and the drain port 43 is provided on the bottom wall of the diversion groove 44. The condensed water dripping into the water receiving tank 42 can be further guided to the drain port 43 through the diversion groove 44, facilitating the condensed water to flow into the drain port 43 and facilitating the centralized discharge of the condensed water.

[0091] Further, as shown in Figure 3 and Figure 7 , the bottom wall of the water receiving tank 42 slopes downward in the direction towards the drain port 43, and the drain port 43 is provided at the lowest point of the water receiving tank 42. Thus, it is convenient for the condensed water dripping into the water receiving tank 42 to automatically flow towards the drain port 43, and it is convenient for the condensed water to be automatically collected and discharged through the drain port 43. Among them, the bottom wall of the diversion groove 44 slopes downward in the direction towards the drain port 43, facilitating the condensed water in the diversion groove 44 to automatically flow towards the drain port 43 and facilitating the automatic centralized discharge of the condensed water through the drain port 43.

[0092] In some embodiments of the present invention, the projection of the drain port 43 on the chassis 11 is located between the projection of the heat exchanger 2 on the chassis 11 and the projection of the gas-liquid separator 7 on the chassis 11. Among them, the drain port 43 faces the chassis 11 below, and the condensed water dripping from the upper pipeline of the compressor 5 is collected and centrally discharged at the drain port 43. The discharged condensed water passes through the gap between the gas-liquid separator 7 and the shell-and-tube heat exchanger 2 and reaches the chassis 11. The discharge of the condensed water avoids the gas-liquid separator 7 and the shell-and-tube heat exchanger 2, preventing the condensed water from damaging the gas-liquid separator 7 and the shell-and-tube heat exchanger 2.

[0093] In some embodiments of the present invention, as shown in Figure 1 , Figure 14 and Figure 15 , one side of the heat exchanger 2 facing away from the blower cavity is provided with a water inlet joint 241 and a water outlet joint 251. The water inlet joint 241 and the water outlet joint 251 are respectively communicated with the inner space of the inner tube through an inlet pipe 24 and an outlet pipe 25. The outdoor unit 100 further includes a mounting plate 8. The mounting plate 8 is located on one side of the heat exchanger 2 facing away from the blower cavity and is connected to the water inlet joint 241 and the water outlet joint 251. Thereby, the welding precision between the water inlet joint 241 and the water outlet joint 251 can be improved, avoiding directly welding the water inlet joint 241 and the water outlet joint 251 on the entire sheet metal part on the side of the housing 1 facing away from the blower cavity, such as the following mounting side plate, which may cause a deviation in the alignment of the through holes on the mounting side plate with the water inlet joint 241 and the water outlet joint 251, resulting in a reduction in welding precision. At the same time, it can also reduce the deviation in the installation position of the heat exchanger 2 in the housing 1 caused by the alignment of the water inlet joint 241 and the water outlet joint 251 with the through holes.

[0094] As shown inFigure 14 and Figure 15 As shown in Figure 15 , a second bracket 22 is provided on the side of the heat exchanger 2 facing away from the blower chamber. The second bracket 22 is connected to the mounting plate 8. The mounting plate 8 is connected to the heat exchanger 2 through the second bracket 22, which facilitates the fixation of the water inlet joint 241 and the water outlet joint 251. When performing external engineering pipe connection, the water inlet joint 241 and the water outlet joint 251 will be subjected to torsion. Since the mounting plate 8 is fixed to the second bracket 22, the torsion effect on the water inlet pipe 24 and the water outlet pipe 25 is greatly reduced.

[0095] Among them, after the gas-liquid separator 7 and the heat exchanger 2 are connected, they form an integral body. The mounting plate 8 is mounted on the heat exchanger 2 through the second bracket 22, and then the whole is mounted on the chassis 11 of the outdoor unit 100.

[0096] Optionally, the water inlet joint 241 and the water outlet joint 251 are connected to the mounting plate 8 through fasteners.

[0097] In some embodiments of the present invention, as Figure 15 shown, the upper end of the second bracket 22 has a positioning extension 221, and the upper end of the mounting plate 8 has a positioning flange 81 bent toward the second bracket 22. The surface of the positioning extension 221 abuts against the surface of the positioning flange 81. For example, the upper end of the positioning extension 221 abuts against the lower surface of the positioning flange 81. Thus, when connecting the second bracket 22 and the mounting plate 8, it can play a positioning role without aligning holes, which facilitates the fixed connection between the second bracket 22 and the mounting plate 8.

[0098] In some embodiments of the present invention, the housing 1 includes a mounting side plate, the mounting side plate is located on the side of the compressor chamber 16 facing away from the blower chamber, the mounting plate 8 is provided on the mounting side plate, and the mounting side plate has two through holes respectively opposite to the water inlet joint 241 and the water outlet joint 251 for connecting the external water pipe to the water inlet joint 241 and the water outlet joint 251. In this application, when performing external engineering pipe connection, the water inlet joint 241 and the water outlet joint 251 will be subjected to torsion. Since the mounting plate 8 is not directly fixed to the mounting side plate, the mounting side plate will not receive the force transmission and will not be affected.

[0099] In some other embodiments of the present invention, the housing 1 includes a mounting side plate, the mounting side plate is provided with a mounting opening, and the mounting plate 8 is provided at the mounting opening. The mounting plate 8 can block the mounting opening, and the mounting opening can be used for connecting the external water pipe to the water inlet joint 241 and the water outlet joint 251.

[0100] During the installation process, the water inlet joint 241 and the water outlet joint 251 are first fixed to the mounting plate 8 as a component, and then this component is pre-positioned and installed with the second bracket 22, and then this component is welded to the heat exchanger 2. At this time, the mounting plate 8 serves as a welding tooling, which can ensure the relative positions of the water inlet joint 241 and the water outlet joint 251 with respect to the mounting plate 8 after welding, avoid hole position deviation during installation, and there is no need to fix the water inlet joint 241 and the water outlet joint 251, improving the efficiency.

[0101] In some embodiments of the present invention, as Figure 14 and Figure 15 shown, a third bracket 23 is provided at the front end of the heat exchanger 2, and the lower end of the third bracket 23 is connected to the chassis 11. Thus, the connection between the heat exchanger 2 and the chassis 11 can be realized, and the fixation of the heat exchanger 2 can be achieved. Optionally, the third bracket 23 and the chassis 11 are connected by fasteners, and the third bracket 23 and the heat exchanger 2 are connected by welding.

[0102] Furthermore, as Figure 14 and Figure 15 shown, the lower end of the third bracket 23 is provided with a second insertion piece 231 extending downward, and the chassis 11 is provided with a second positioning hole that cooperates with the second insertion piece 231. Thus, when installing the heat exchanger 2, the second insertion piece 231 can be inserted into the second positioning hole and then the third bracket 23 can be connected to the chassis 11 by fasteners. The cooperation between the second insertion piece 231 and the second positioning hole can play a role in pre-positioning, so that there is no need to align the holes when the third bracket 23 and the chassis 11 are connected, improving the assembly efficiency.

[0103] Furthermore, as Figure 14 and Figure 15 shown, the upper end of the third bracket 23 is connected to the front bracket 31. The front bracket 31 is connected to the chassis 11, and the upper end of the third bracket 23 is connected to the front bracket 31. Thus, the reliability of the connection between the third bracket 23 and the chassis 11 can be increased, and thereby the reliability of the fixation of the heat exchanger 2 can be improved.

[0104] Optionally, the upper end of the third bracket 23 and the front bracket 31 are connected by fasteners.
