Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner outdoor unit and an air conditioner. Background Art

[0002] Air conditioners are essential appliances in our daily lives, available in a wide variety of structural forms. With the continuous advancement of industrial design and the application of new processes, materials, and designs to air conditioners, not only have a wide variety of indoor units been developed, but outdoor units have also undergone corresponding structural optimization.

[0003] Existing air conditioner outdoor units enter defrost mode after a period of heating in cold climates. This process causes meltwater to fall from the outdoor unit's condenser into the chassis, where it collects and forms a thick layer of ice. While existing technologies incorporate drainage channels within the chassis, ice still accumulates in the cold, posing safety risks such as condenser cracking and blade breakage caused by ice striking the fan blades.

[0004] Existing technology often involves defrosting the chassis. Currently, in the domestic air conditioning industry, chassis defrosting often involves adding an electric heater. This works by applying power to the heater, which generates heat from an internal resistor to remove ice. However, this method not only increases air conditioner manufacturing costs but also consumes additional power during heating.

[0005] Therefore, how to fundamentally solve the problems of water accumulation and ice formation in the chassis during the air-conditioning heating process has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of this, the present invention aims to provide an air conditioner outdoor unit and an air conditioner to solve the problem in the prior art that water easily accumulates and ice forms on the chassis during the air conditioning heating process.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] An air conditioner outdoor unit includes a condenser assembly and a chassis, wherein the condenser assembly is disposed on the outside of the chassis; the condenser assembly includes a left panel and a right panel, wherein a heat exchange tube at one end of the condenser assembly passes through the left panel and is fixedly connected to the left panel, and a heat exchange tube at the other end of the condenser assembly passes through the right panel and is fixedly connected to the right panel; the left panel and the right panel are respectively fixedly connected to the chassis for fixing the condenser assembly to the chassis; one end of a bracket assembly is fixedly connected to the chassis, and the other end of the bracket assembly is at least in contact with the top of the condenser assembly. By locating the condenser assembly on the outside of the chassis, the problems of water accumulation and ice formation in conventional air conditioners are fundamentally avoided, and safety hazards such as condenser cracking due to freezing or blades striking ice, which may cause blade breakage, are avoided. Furthermore, the need for adding an electric heating strip to the chassis or providing a drainage channel in the chassis is eliminated, which not only simplifies the chassis structure and reduces the manufacturing cost of the air conditioner, but also avoids the need for electric heating to melt ice, thereby reducing the additional power consumption of the air conditioner. At the same time, the setting of the bracket assembly can not only limit the freedom of the condenser assembly in the vertical direction, but also support at least the top of the condenser assembly in the horizontal direction, thereby preventing the condenser assembly from tipping over during the transportation of the air-conditioning outdoor unit, which is beneficial to improving the assembly reliability of the condenser assembly.

[0009] Furthermore, a first flange is provided on the outer edge of the chassis, and the first flange is in contact with at least part of the fin structure of the condenser assembly on the side away from the chassis, or the condenser assembly as a whole is separated from the first flange; thus, a conventional chassis structure can be directly adopted, and there is even no need to make too many changes to the conventional chassis structure. On the basis of a conventional air-conditioning outdoor unit, it can not only reduce the cost of redesigning, manufacturing, and replacing various components to the greatest extent, but also does not require too many or too large changes to the air-conditioning production line.

[0010] Furthermore, a first assembly hole is provided at one end of the left side plate close to the chassis, and a corresponding first fixing hole is provided on the left side of the chassis.

Thus, by providing the wind-blocking plate, on the one hand, the space above the chassis is divided into mutually independent fan assembly areas and compressor assembly areas, so that the internal related components of the air conditioner outdoor unit will not interfere with each other during operation; on the other hand, it can simply and conveniently realize the fixed connection between the right side panel and the chassis through the wind-blocking plate, and at the same time, it can provide multiple fixing points at the upper part, middle part, etc. of the condenser assembly to enhance the connection reliability between the condenser assembly and the chassis.

[0012] Furthermore, the air-conditioning outdoor unit includes a base, which is connected to the chassis, and the supporting end of the base extends to the bottom of the condenser assembly. The bottom of the condenser assembly is in contact with the supporting end, so that the supporting end can bear the gravity of the condenser assembly in the vertical direction, and optimize the distribution of force points during fixed assembly of the condenser assembly, which is beneficial to improving the force distribution of related assembly force points and reducing the force between the condenser assembly and the chassis; at the same time, through the joint action of the base and the bracket assembly, the condenser assembly can be limited and fixed in the vertical direction, which can not only effectively fix and support the condenser assembly and improve the assembly reliability of the condenser assembly, but also effectively prevent the condenser assembly from tipping over and deformation during the actual transportation, installation and use of the air-conditioning outdoor unit.

[0013] Furthermore, the bracket assembly includes a condenser bracket, and the condenser bracket includes a first frame and a second frame, the bottom end of the first frame is fixedly connected to the chassis, the top end of the first frame is connected to the second frame, one end of the second frame is connected to the front panel and / or top cover flange of the air-conditioning outdoor unit, and the other end of the second frame extends to the top of the condenser assembly and abuts against the top of the condenser assembly; thereby, through the setting of the condenser bracket, not only the vertical freedom of the condenser assembly can be restricted, but also a mutual support effect can be generated between the front panel and / or top cover and the condenser assembly in the front and rear directions of the air-conditioning outdoor unit at the same time, and the source of the supporting force is located inside the air-conditioning outdoor unit between the front panel, top cover, chassis and condenser assembly, which can effectively fix and support the condenser assembly and the outdoor unit housing assembly, improve the assembly reliability of the condenser assembly, and effectively prevent the condenser assembly from tipping over, deformation, and fixation failure during the actual transportation, installation and use of the air-conditioning outdoor unit.

[0014] Furthermore, the chassis is provided with a second assembly boss, and the bottom end of the first frame is provided with a bottom flange, the bottom flange has an assembly folding edge, the second assembly boss is provided with an assembly bevel, and the assembly folding edge is fixedly connected to the assembly bevel; the bottom flange is provided with a snap-in hole, and the second assembly boss is provided with a snap-in protrusion, and the snap-in protrusion is snapped with the snap-in hole; thereby, relative to the horizontal plane, the assembly folding edge and the assembly bevel are both inclined upward, and on the one hand, the assembly of the first frame is positioned and limited by the snap-in protrusion, and then assembled on the inclined assembly surface, which is convenient for assembly operation, and on the other hand, the connection reliability between the first frame and the chassis is further ensured, so as to improve the assembly reliability of the condenser bracket as a whole to the condenser assembly.

[0015] The front end of the second frame is provided with a front flange, and the front flange is fixedly connected to the inner side surface of the front panel and / or the inner side surface of the top cover flange; second side flanges are provided on both sides of the second frame, and a wing plate is provided at the rear end of the second frame, and the wing plate abuts against the top end of the condenser assembly, and the rear end of the second side flange abuts against the front side surface of the condenser assembly; thereby, the second frame can generate a clamping force on the condenser assembly, which is beneficial to improving the assembly reliability of the condenser assembly on the one hand, and on the other hand, the second frame can support the front panel and / or top cover and the condenser assembly at the same time, which can effectively prevent the condenser assembly from tipping over and prevent the condenser assembly from failing in assembly and fixation.

[0016] The cam is secured to the chassis and / or to the camshaft when the fan is in a position to move relative to the first frame and to prevent the fan from sliding out of the chassis.

[0017] An air conditioner comprises the air conditioner outdoor unit.

[0018] Compared with the prior art, the air conditioner outdoor unit and the air conditioner described in the present invention have the following advantages:

[0019] The air conditioner outdoor unit and air conditioner described in the present invention fundamentally avoid the problems of water accumulation and ice formation in the chassis of conventional air conditioners by arranging the condenser assembly on the outside of the chassis, and avoid the occurrence of air conditioner safety hazards such as condenser freezing and cracking, and fan blades hitting ice cubes and causing fan blades to break; at the same time, it also eliminates the need to add electric heating belts to the chassis, or to provide drainage channels in the chassis, which not only helps to simplify the structure of the chassis and reduce the manufacturing cost of the air conditioner, but also avoids electric heating to melt ice, thereby reducing the extra power consumption of the air conditioner.

[0020] At the same time, the setting of the bracket assembly can not only limit the freedom of the condenser assembly in the vertical direction, but also support at least the top of the condenser assembly in the horizontal direction to prevent the condenser assembly from tipping over, which is beneficial to improving the assembly reliability of the condenser assembly.

DETAILED DESCRIPTION

[0035] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The directional terms in this application are based on the air conditioner outdoor unit in a normal placement or normal installation state.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] In existing technology, after an air conditioner has been heating in cold regions for a period of time, the system enters defrost mode. The meltwater produced by defrosting often falls from the outdoor unit's condenser into the chassis and collects there, causing a thick layer of ice to form. At this point, the chassis needs to be defrosted. Currently, the domestic air conditioner industry often defrosts the chassis by adding an electric heating strip. This works by applying power to the electric heater, which heats up the internal resistor wire to remove ice. However, this method not only increases the cost of the air conditioner's manufacturing process, but also results in additional power consumption during heating.

[0039] In order to solve the problem of water accumulation and ice formation in the chassis during the heating process of the air conditioner in the prior art, this embodiment proposes an air conditioner outdoor unit, as shown in the attached Figure 1-11As shown, the air-conditioning outdoor unit includes a condenser assembly 2 and a chassis 4, and the condenser assembly 2 is arranged on the outside of the chassis 4; compared with the prior art of installing the condenser on the inside of the chassis, the present application arranges the condenser assembly 2 on the outside of the chassis 4, so that when the air-conditioning is in defrosting mode, water dripping from the condenser assembly 2 will not fall into the chassis 4, but will fall outside the chassis 4, thereby fundamentally avoiding the problems of water accumulation and ice formation in the chassis of conventional air-conditioning, and avoiding the occurrence of air-conditioning safety hazards such as condenser freezing and cracking, and fan blades hitting ice cubes causing fan blades to break; at the same time, it also eliminates the need to add electric heating belts to the chassis, or to open drainage channels on the chassis, which is not only conducive to simplifying the structure of the chassis and reducing the manufacturing cost of the air-conditioning, but also avoids electric heating to melt ice, thereby reducing the extra power consumption of the air-conditioning.

[0040] Of course, the design concept of placing the condenser assembly 2 on the outside of the chassis 4 still faces the problem of fixed assembly of the condenser assembly 2. This application further introduces the relevant structure: the condenser assembly 2 is basically the same as the condenser structure in the prior art, and has conventional structures such as heat exchange coils and fins. In addition, the condenser assembly 2 also includes a left side plate 5 and a right side plate 6. The heat exchange tube at one end of the heat exchange coil passes through the left side plate 5 and is fixedly connected to the left side plate 5 by means of an expansion tube assembly. The heat exchange tube at the other end of the heat exchange coil passes through the right side plate 6 and is also fixedly connected to the right side plate 6 by means of an expansion tube assembly. The expansion tube assembly of the plate body and the coil structure is a conventional assembly process technology in the field of air-conditioning heat exchanger production and will not be described in detail here. The left side plate 5 and the right side plate 6 are respectively fixedly connected to the chassis 4 for fixed assembly of the condenser assembly 2 and the chassis 4. Therefore, based on the design concept of arranging the condenser assembly 2 on the outside of the chassis 4, the condenser assembly 2 can be simply and conveniently connected to the chassis 4 to achieve fixed assembly of the condenser assembly 2.

[0041] The left side plate 5 is provided with a first assembly hole at one end close to the chassis 4, and a corresponding first fixing hole is provided on the left side of the chassis 4. Therefore, during the assembly process, the first assembly hole is aligned with the first fixing hole, and then a fastener such as a screw is screwed into the first assembly hole and the first fixing hole to achieve a fixed connection between the left side plate 5 and the chassis 4.

[0042] The air conditioner outdoor unit includes a wind-blocking upright plate 3, and the wind-blocking upright plate 3 is fixedly connected to the right side plate 6 and the chassis 4 respectively, or in other words, the right side plate 6 is fixedly connected to the chassis 4 through the wind-blocking upright plate 3. Specifically, the wind-blocking upright plate 3 is provided with a second assembly hole at one end close to the chassis 4, and the chassis 4 is provided with a corresponding second fixing hole. During the assembly process, the second assembly hole is aligned with the second fixing hole, and then screws and other fasteners are screwed into the second assembly hole and the second fixing hole to achieve a fixed connection between the wind-blocking upright plate 3 and the chassis 4; on this basis, third assembly holes are provided at multiple locations such as the upper part and the middle part of the right side plate 6, and the wind-blocking upright plate 3 is provided with a corresponding third fixing hole on the side close to the right side plate 6. During the assembly process, the third assembly holes are aligned with the third fixing holes one by one, and then screws and other fasteners are screwed into the second assembly holes and the second fixing holes. The fasteners are screwed into the third assembly hole and the third fixing hole to achieve a fixed connection between the wind-isolating vertical plate 3 and the right side plate 6; thus, through the setting of the wind-isolating vertical plate 3, on the one hand, the space above the chassis 4 is divided into mutually independent fan assembly areas and compressor assembly areas, so that the internal related components of the air-conditioning outdoor unit will not interfere with each other during operation; on the other hand, the right side plate 6 can be simply and conveniently fixed to the chassis 4 through the wind-isolating vertical plate 3, and at the same time, by providing multiple fixing points at the upper and middle parts of the condenser assembly 2, the connection reliability between the condenser assembly 2 and the chassis 4 is enhanced.

[0043] The condenser assembly 2 is arranged on the outside of the chassis 4, and the outer edge of the chassis 4 is provided with a first flange 41, which is basically the same as the structure of a conventional chassis and will not be described in detail; on this basis, the condenser assembly 2 is arranged on the side of the first flange 41 away from the chassis 4; as shown in the attached Figure 3 As shown, at least part of the fin structure of the condenser assembly 2 is in contact with the side of the first flange 41 away from the chassis 4; of course, the fin can also be completely out of contact with the first flange 41, so that the condenser assembly 2 and the first flange 41 are in a state of separation from each other. Therefore, the present application can directly adopt a conventional chassis structure, and there is no need to make too many changes to the conventional chassis structure. It is only necessary to set corresponding fixing holes in the chassis 4, and then remove the condenser set in the chassis 4 in the traditional outdoor unit, change the conventional installation position of the condenser, and fix it on the outside of the chassis 4; of course, the structure of the conventional condenser can also be adaptively adjusted, which will not be described here. This design concept of the present application, based on the conventional air-conditioning outdoor unit, can not only reduce the cost of redesigning, manufacturing, and replacing each component to the greatest extent, but also does not require too many or too large changes to the air-conditioning production line. When the air-conditioning manufacturer updates its technology and production line, it is beneficial to save its manpower and material resources.

[0044] In addition, since the condenser assembly 2 is arranged on the outside of the chassis 4, with the actual installation of the air-conditioning outdoor unit, at least part of the structure of the condenser assembly 2 or the entirety is in a suspended state. In order to limit the freedom of the condenser assembly 2 in the vertical direction, this application further introduces the relevant structure of the air-conditioning outdoor unit.

[0045] The air conditioner outdoor unit includes a base 7, which is connected to the chassis 4. One end of the base 7 extends toward the condenser assembly 2 and extends to the bottom of the condenser assembly 2. The end of the base 7 located below the condenser assembly 2 is recorded as a support end 71. The bottom of the condenser assembly 2 is fitted with the support end 71, so that the support end 71 can bear the gravity of the condenser assembly 2 in the vertical direction, and optimize the distribution of force points of the condenser assembly 2 during fixed assembly, which is conducive to improving the force distribution of related assembly force points and reducing the force between the condenser assembly 2 and the chassis 4.

[0046] In addition, as for the structure of the base 7, the base 7 is preferably a conventional support beam, and the base 7 is fitted with the bottom surface of the chassis 4. The base 7 and the bottom surface of the chassis 4 are fixedly connected by fasteners, so that the base 7 can not only support the entire air-conditioning outdoor unit, but also bear the gravity of the condenser assembly 2.

[0047] In addition, the air conditioner outdoor unit also includes a bracket assembly, one end of which is fixedly connected to the chassis 4, and the other end of the bracket assembly is at least in contact with the top of the condenser assembly 2, thereby further limiting the freedom of the condenser assembly 2 in the vertical direction.

[0048] The bracket assembly includes a condenser bracket 8, the bottom of the condenser bracket 8 is fixedly connected to the chassis 4, one end of the top of the condenser bracket 8 is connected to the front panel and / or top cover flange of the air-conditioning outdoor unit, and the other end of the top of the condenser bracket 8 extends to the top of the condenser assembly 2 and abuts against the top of the condenser assembly 2; specifically, the condenser bracket 8 includes a first frame 81 and a second frame 82, the bottom end of the first frame 81 is fixedly connected to the chassis 4, the top of the first frame 81 is connected to the second frame 82, one end of the second frame 82 is connected to the front panel and / or top cover flange of the air-conditioning outdoor unit, and the other end of the second frame 82 extends to the top of the condenser assembly 2 and abut against the top of the condenser assembly 2, thereby not only limiting the freedom of the condenser assembly 2 in the vertical direction, but also generating a mutual support effect between the front panel and / or top cover and the condenser assembly 2 in the front-to-back direction of the air-conditioning outdoor unit, and the source of the supporting force is located inside the air-conditioning outdoor unit between the front panel, top cover, chassis 4 and condenser assembly 2, which can effectively fix and support the condenser assembly 2 and the outdoor unit casing components, improve the assembly reliability of the condenser assembly 2, and effectively prevent the condenser assembly 2 from tipping over, deformation, fixation failure, etc. during the actual transportation, installation and use of the air-conditioning outdoor unit.

[0049] The first frame 81 and the second frame 82 can be separate structures or can be integrally stamped from sheet metal. However, considering the difficulty of processing and the overall strength of the condenser bracket 8 after processing, the present application prefers that the first frame 81 and the second frame 82 are separate structures.

[0050] As for the connection between the first frame 81 and the chassis 4, the chassis 4 is provided with a second assembly boss 43, the first frame 81 is preferably arranged vertically, and a bottom flange 812 is provided at the bottom end of the first frame 81, and the bottom flange 812 has an assembly fold 813, and the second assembly boss 43 is provided with a corresponding assembly bevel 46, and the assembly fold 813 and the assembly bevel 46 are fixedly connected by fasteners such as screws, thereby realizing the connection between the first frame 81 and the chassis 4; at the same time, relative to the horizontal plane, the assembly fold 813 and the assembly bevel 46 are both inclined upward, avoiding possible spatial interference, so that when the first frame 81 and the chassis 4 are assembled, the assembly worker can easily assemble the fasteners on the front side of the external unit, reducing the difficulty of the assembly operation.

[0051] The bottom flange 812 is provided with a snap-in hole 814, and the second assembly boss 43 is provided with a snap-in protrusion 44. When the first frame 81 is assembled with the chassis 4, the snap-in protrusion 44 is snapped into the snap-in hole 814. On the one hand, it positions and limits the assembly of the first frame 81, and on the other hand, it is beneficial to improve the connection reliability between the first frame 81 and the chassis 4, and further improve the assembly reliability of the condenser bracket 8 to the condenser assembly 2 as a whole.

[0052] In addition, the first frame 81 is connected to the upper end surface of the chassis 4. In conventional air conditioners, the base 7 of the air conditioner outdoor unit is often connected to the lower end surface of the chassis 4. In order to further improve the connection reliability of the bottom end of the first frame 81, first side flanges 811 are provided on both sides of the first frame 81, and corresponding through grooves 45 are provided on the second assembly bosses 43. The bottom end of the first side flange 811 extends and passes through the through grooves 45, and the bottom end of the first side flange 811 is connected to the base 7 of the air conditioner outdoor unit. The specific connection method can be conventional connection methods such as snap connection, fastener connection, and riveting. This can further improve the connection reliability of the bottom of the condenser bracket 8 and improve the assembly reliability of the condenser bracket 8 to the condenser assembly 2.

[0053] As for the connection between the first frame 81 and the second frame 82, first side flanges 811 are provided on both sides of the first frame 81, and second side flanges 822 are provided on both sides of the second frame 82. The top of the first side flange 811 is fixedly connected to the second side flange 822 by screws or other fasteners. In the present application, the second frame 82 is preferably arranged horizontally, so that a structure similar to a T-shape is formed between the first frame 81 and the second frame 82, so that the condenser bracket 8 can form a force support point with the shell component (front panel and / or top cover) of the external unit, the chassis 4, and the condenser assembly 2, respectively, which is conducive to improving the overall assembly reliability of the condenser bracket 8 to the condenser assembly 2.

[0054] As for the connection between the second frame 82 and the shell assembly and the condenser assembly 2, a front flange 821 is provided at the front end of the second frame 82, and the front flange 821 is in contact with the inner side surface of the front panel and / or the inner side surface of the top cover flange, and the front flange 821 is fixedly connected to the front panel and / or the top cover flange by fasteners such as screws; a wing plate 823 is provided at the rear end of the second frame 82, and the wing plate 823 abuts against the top end of the condenser assembly 2, and the rear end of the second side flange 822 abuts against the front side surface of the condenser assembly 2, so that the second frame 82 can generate a clamping force on the condenser assembly 2, which is beneficial to improve the assembly reliability of the condenser assembly 2 on the one hand, and on the other hand, the second frame 82 can support the front panel and / or top cover and the condenser assembly 2 at the same time, which can effectively prevent the condenser assembly 2 from tipping over and prevent the condenser assembly 2 from failing in assembly and fixation.

[0055] While the second frame 82 can simultaneously support the front panel and / or top cover, as well as the condenser assembly 2, it is also subject to forces acting in the fore-and-aft direction. The second frame 82 is provided with at least one weight-reducing hole 824, preferably an elliptical hole, with its major axis parallel to the fore-and-aft direction of the air conditioner outdoor unit. The provision of these specific weight-reducing holes 824 not only helps reduce the weight of the condenser bracket 8, facilitating production and transportation, but also effectively improves the force distribution on the second frame 82, particularly in the fore-and-aft direction of the air conditioner outdoor unit, thereby ensuring the mechanical strength of the second frame 82.

[0056] In addition, the bracket assembly includes a fan bracket 1. The fan bracket 1 is the same as a conventional fan bracket and can fix and support the fan. The assembly of the fan bracket and the fan is the same as in the prior art and will not be described in detail. The bottom end of the fan bracket 1 is fixedly connected to the chassis 4 by fasteners such as screws, and the top end of the fan bracket 1 is engaged with the top of the condenser assembly 2. This not only limits the vertical freedom of the condenser assembly 2, but also supports the top of the condenser assembly 2 in the horizontal direction to prevent the condenser assembly 2 from tipping over during transportation of the air conditioner outdoor unit. The location of the fan bracket 1 is related to the assembly position of the fan. In the prior art, it is often located near the middle of the chassis 4, which basically corresponds to the middle position of the condenser assembly 2. Therefore, the top end of the fan bracket 1 can be engaged with the middle position of the top end of the condenser assembly 2. This makes it easier to further ensure the horizontal support of the condenser assembly 2 without making too many changes to the conventional fan bracket assembly position.

[0057] Specifically, the fan bracket 1 includes a first bracket 11, a second bracket 12, and a clamping member 13. The first bracket 11 is vertically arranged, and the bottom end of the first bracket 11 is fixedly connected to the chassis 4 by screws and other fasteners. One end of the second bracket 12 is connected to the top of the first bracket 11, and the other end of the second bracket 12 extends toward the front panel of the air-conditioning outdoor unit, and is fixed to the front panel and / or the top cover flange of the air-conditioning outdoor unit by screws and other fasteners; one end of the clamping member 13 is connected to the top of the first bracket 11 and / or the second bracket 12, and the other end of the clamping member 13 extends toward the condenser assembly 2. The clamping member 13 is provided with a claw 14 near the condenser assembly 2, and the claw 14 is clamped with the top of the condenser assembly 2. The fan bracket 1 is specifically designed to provide support for the front panel and / or top cover, and the condenser assembly 2, in the front-to-back direction of the air conditioner outdoor unit, while being fixedly connected to the chassis 4. The source of this support is located within the air conditioner outdoor unit, between the front panel, top cover, chassis 4, and condenser assembly 2. This effectively secures and supports the condenser assembly 2 and the outdoor unit housing, while also preventing the condenser assembly 2 from tipping over or deforming during transportation. The first bracket 11, second bracket 12, and clip 13 may be separate structures or integrally stamped from sheet metal.

[0058] In addition, for the connection between the first bracket 11 and the chassis 4, a first assembly boss 42 can also be provided on the chassis 4.
