Description

Technical Field

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

[0002] Air conditioners typically consist of major components such as compressors and heat exchangers. The compressor drives the refrigerant circulation, while the heat exchanger acts as an evaporator or condenser to release and absorb heat, thereby regulating the ambient temperature.

[0003] Split-type air conditioners consist of an indoor unit and an outdoor unit. The outdoor unit contains a compressor, an outdoor heat exchanger, and an outdoor fan. The outdoor unit typically has a partition that divides its interior into a compressor compartment and a fan compartment. The compressor is located in the compressor compartment, while the outdoor heat exchanger and outdoor fan are located in the fan compartment.

[0004] In the outdoor units of air conditioners, the reactor is usually installed on the partition inside the compressor compartment. Because the reactor is heavy, the partition needs to be strong and have a large installation space, which cannot meet the installation and heat dissipation requirements of the reactor. Utility Model Content

[0005] The purpose of this utility model is to provide an outdoor unit for an air conditioner to solve the problems of reactor installation and heat dissipation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: According to one aspect of the present invention, an outdoor unit for an air conditioner is provided, comprising: a housing forming the outer shell of the outdoor unit; a fan compartment disposed within the housing; a motor bracket disposed within the fan compartment and extending along the height direction of the housing; the motor bracket comprising: a first vertical rod extending along the height direction of the housing; a second vertical rod extending along the height direction of the housing and spaced parallel to the first vertical rod; and an outdoor fan disposed within the fan compartment and fixed to the first vertical rod. On a first vertical pole and a second vertical pole; a reactor assembly, the reactor assembly being disposed within the wind turbine housing, the reactor assembly comprising: a base, the base being disposed on the side of the first vertical pole and the second vertical pole away from the outdoor wind turbine, and fixedly connected to the first vertical pole and the second vertical pole; a reactor, the reactor being fixed to the side of the base near the outdoor wind turbine, and disposed between the first vertical pole and the second vertical pole; an outer cover, the outer cover being disposed on the side of the base near the outdoor wind turbine, and covering the outer periphery of the reactor; the outer cover being disposed between the first vertical pole and the second vertical pole.

[0007] The above-mentioned technical solution has the following advantages or beneficial effects: By arranging the first and second vertical rods along the height direction of the casing, and with the first and second vertical rods spaced apart, and with the base fixed to the side of the motor bracket away from the outdoor fan, part of the space on the side of the motor bracket away from the outdoor fan and part of the space between the first and second vertical rods can be utilized. This allows the reactor and its outer casing of the reactor assembly to be fixed on the motor bracket, and the outdoor fan to dissipate heat from the reactor nearby, thus solving the reactor's heat dissipation problem. It also increases the distance between the outer casing of the reactor assembly and the impeller of the outdoor fan, avoiding interference with the normal rotation of the impeller and solving the reactor installation problem.

[0008] In some embodiments of this application, a receiving cavity is formed between the outer cover and the base, and the receiving cavity extends along the height direction of the housing; the reactor is disposed in the receiving cavity, and at least two reactors are provided, and at least two reactors are arranged sequentially and at intervals along the height direction of the housing in the receiving cavity.

[0009] The above-mentioned technical solution has the following advantages or beneficial effects: It can utilize the space of the motor bracket in the height direction within the fan housing to expand the height space of the housing cavity, facilitating the arrangement of multiple reactors within the housing and solving the problem of accommodating and installing multiple reactors. By arranging multiple reactors sequentially and at intervals along the height direction of the casing within the housing cavity, the space requirement in the width direction of the housing can be reduced, fully utilizing the height space inside the casing, and further fully utilizing the height space of the motor bracket, thus solving the difficulty of not being able to accommodate multiple reactors within the compressor compartment of a compact outdoor unit.

[0010] In some embodiments of this application, the width of the outer cover is less than the distance between the first vertical rod and the second vertical rod, so that the outer cover passes through the gap between the first vertical rod and the second vertical rod and is connected to the base.

[0011] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the width of the outer cover, the outer cover can be arranged in the gap area between the first vertical rod and the second vertical rod, which makes it easy for the outer cover to pass through the gap area between the first vertical rod and the second vertical rod and to be connected to the base, making full use of the gap space between the first vertical rod and the second vertical rod, and solving the problem of accommodating and installing the outer cover and the reactor.

[0012] In some embodiments of this application, a first fixed wall and a second fixed wall are respectively provided on opposite sides of the base, the first fixed wall being fixed to the first vertical rod and the second fixed wall being fixed to the second vertical rod.

[0013] The above-mentioned technical solution has the following advantages or beneficial effects: by cooperating with the first fixed wall and the second fixed wall, the base can be stably fixed on the side away from the outdoor fan in the interval area between the first vertical rod and the second vertical rod, making full use of the interval area between the first vertical rod and the second vertical rod, and solving the problem of accommodating and installing the reactor and the outer casing.

[0014] In some embodiments of this application, the base has a recessed receiving groove on the side facing the gap between the first vertical rod and the second vertical rod, the receiving groove is arranged opposite to and communicates with the gap; the reactor is arranged in the receiving groove, and the outer cover is provided in the receiving groove and the gap.

[0015] The above-mentioned technical solution has the following advantages or beneficial effects: by connecting the accommodating groove of the base with the interval area between the first vertical rod and the second vertical rod, the space inside the base and the outer casing can be shifted to the side away from the outdoor fan, which is conducive to increasing the distance between the casing and the impeller of the outdoor fan, avoiding affecting the normal rotation of the impeller, making full use of the space of the accommodating groove and the interval area, and solving the problem of accommodating and installing the reactor and the outer casing.

[0016] In some embodiments of this application, the receiving groove extends along the height direction of the housing; at least two reactors are arranged sequentially and at intervals along the height direction of the housing within the receiving groove.

[0017] The above technical solution has the following advantages or beneficial effects: by extending the receiving groove along the height direction of the casing, installation space can be provided for the reactor in the height direction of the casing, so that multiple reactors can be arranged sequentially and at intervals in the receiving groove along the height direction of the casing.

[0018] In some embodiments of this application, the outer wall of the outer cover is provided with heat dissipation holes; the reactor assembly includes: a waterproof cover, which covers the outer wall of the outer cover and covers the outside of the heat dissipation holes; a heat dissipation channel is formed between the waterproof cover and the outer wall of the outer cover, and the heat dissipation channel communicates with the fan compartment; the heat dissipation holes communicate with the accommodating cavity and the heat dissipation channel.

[0019] The above-mentioned technical solution has the following advantages or beneficial effects: the accommodating cavity can be connected to the ventilation chamber through heat dissipation holes and channels, allowing the heat inside the accommodating cavity to be discharged to the ventilation chamber outside the box through the heat dissipation holes and channels. Air from the ventilation chamber can also enter the accommodating cavity inside the box through the heat dissipation channels and holes, thereby achieving heat dissipation of the reactor inside the box and improving the reactor's heat dissipation efficiency.

[0020] In some embodiments of this application, a plurality of heat dissipation holes are provided, and the plurality of heat dissipation holes are arranged sequentially at intervals along the height direction of the outer cover; the heat dissipation channel extends along the height direction of the outer cover, and the upper and lower ends of the heat dissipation channel are respectively connected to the fan compartment; a rainproof wall is provided on the top side edge of the heat dissipation hole, which extends outward and downward, and the rainproof wall is located inside the heat dissipation channel.

[0021] The above-mentioned technical solution has the following advantages or beneficial effects: The upper and lower ends of the heat dissipation channel allow airflow within the fan compartment, creating a cooling airflow. This cooling airflow can enter the housing through the heat dissipation holes, dissipating heat from the containment cavity and reactor. This cooling airflow can also draw air and heat from the containment cavity, further dissipating heat from the reactor. The inclined rainproof wall shields the outside of the heat dissipation holes, allowing rainwater entering from the top opening of the heat dissipation channel to flow downwards along the rainproof wall, preventing rainwater from entering the housing through the heat dissipation holes and thus improving the rainproof performance of the reactor assembly.

[0022] In some embodiments of this application, the outer wall of the outer casing is provided with a wire outlet hole, and the side wall of the base is provided with a wire passage hole.

The wire outlet hole is located on the side wall of the outer casing in the region between two adjacent reactors, and the wire passage hole is located on the side of the first vertical rod and the second vertical rod away from the outdoor fan.

[0023] The above-mentioned technical solution has the following advantages or beneficial effects: By arranging and connecting the through-hole and outlet holes, the connecting wires of the reactor inside the box can be led out of the box through the outlet hole and the through-hole in sequence. Since the through-hole is located on the side of the first and second vertical rods away from the outdoor fan, the connecting wires of the reactor, after being led out through this through-hole, can be arranged in the back area of ​​the motor bracket. This increases the distance between the connecting wires of the reactor and the impeller of the outdoor fan, preventing the impeller from contacting the connecting wires of the reactor during rotation.

[0024] In some embodiments of this application, the outdoor fan is provided in two sets, and the two sets of outdoor fans are arranged sequentially at intervals along the height direction of the motor bracket, and the reactor assembly is located in the interval area between the two sets of outdoor fans.

[0047] Figure 1 This is a schematic diagram of the structure of the outdoor unit of an air conditioner according to some embodiments of this utility model. Figure 2 yes Figure 1 A schematic diagram of some of the internal structures.

[0048] like Figure 1 and Figure 2 As shown, some embodiments of this application provide an outdoor unit for an air conditioner, which may include a housing 1, which forms the outer casing of the outdoor unit. The interior of the housing 1 can be used to provide installation space.

[0049] In some embodiments, the outdoor unit of the air conditioner may include an outdoor heat exchanger 2, which may be disposed inside the casing 1. The outdoor heat exchanger 2 is used to exchange heat with outdoor air.

[0050] In some embodiments, the outdoor unit of the air conditioner may include a compressor 3, which is connected to an outdoor heat exchanger 2 to form a refrigerant circulation loop. The refrigerant circulates within this loop, consisting of the compressor 3 and the outdoor heat exchanger 2. During the refrigerant circulation, the outdoor heat exchanger 2 can function as either a condenser or an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the outdoor unit. Specifically, during the cooling cycle, the outdoor heat exchanger 2 functions as a condenser. During the heating cycle, the outdoor heat exchanger 2 functions as an evaporator.

[0051] like Figure 2 As shown, in some embodiments, a partition 11 may be provided inside the housing 1, dividing the space inside the housing 1 into a compressor compartment 110 and a fan compartment 120. The fan compartment 120 connects to the outdoor space. The compressor 3 may be located inside the compressor compartment 110. The outdoor heat exchanger 2 may be located inside the fan compartment 120.

[0052] like Figure 1 and Figure 2As shown, in some embodiments, an air inlet 12 is provided on the outer wall of the housing 1, and the air inlet 12 may be located on the peripheral side wall of the housing 1. The air inlet 12 can connect to the outside of the housing 1 and connect the ventilation duct 120 to the outdoor space. The outdoor heat exchanger 2 can be arranged opposite to the air inlet 12. Outdoor air enters the interior of the ventilation duct 120 through the air inlet 12 and exchanges heat with the outdoor heat exchanger 2.

[0053] It should be noted that in other embodiments, the air inlet 12 may also be located in other areas of the outer wall of the housing 1.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, an air outlet 13 is provided on the outer wall of the housing 1, and the air outlet 13 may be located on the front wall of the housing 1. The air outlet 13 can connect to the outside of the housing 1 and connect the ventilation duct 120 and the outdoor space. The air in the ventilation duct 120 that has exchanged heat with the outdoor heat exchanger 2 can be blown to the outside of the housing 1 through the air outlet 13 and return to the outdoor space.

[0055] It should be noted that in other embodiments, the air outlet 13 may also be located in other areas of the outer wall of the housing 1.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the outdoor unit of the air conditioner may include an outdoor fan 4. The outdoor fan 4 may be disposed within the fan compartment 120, and the outdoor fan 4 may be arranged opposite to the air outlet 13. The air intake side of the outdoor fan 4 faces the interior of the fan compartment 120, and the air outlet side of the outdoor fan 4 faces the exterior of the air outlet 13. When the outdoor fan 4 is running, the outdoor fan 4 assembly can introduce outdoor air into the compressor compartment 110 of the casing 1 through the air inlet 12, where it exchanges heat with the outdoor heat exchanger 2. The heat-exchanged air is then discharged outside the casing 1 through the air outlet 13 and into the outdoor space.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the outdoor heat exchanger 2 can be installed on the side wall of the fan compartment 120 near the housing 1, and abut against the inner side wall of the housing 1, and arranged opposite to the air inlet 12.

[0058] In some embodiments, the outdoor unit of the air conditioner may include an electrical control box 6, which may be located inside the compressor compartment 110.

[0059] Figure 3 yes Figure 2 A schematic diagram of the structure of the motor bracket 5, the drive motor 41, and the reactor assembly 7.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the outdoor unit of the air conditioner may include a motor bracket 5, which is disposed inside the housing 1. The motor bracket 5 may be disposed within the fan compartment 120, and the motor bracket 5 provides installation space for the outdoor fan 4. The outdoor fan 4 may be fixedly mounted on the motor bracket 5, and thus fixedly mounted within the fan compartment 120.

[0061] In some embodiments, the motor bracket 5 can extend along the height direction of the housing 1 so that the motor bracket 5 can be arranged vertically. The bottom end of the motor bracket 5 can be connected to the bottom surface inside the housing 1, and the top end of the motor bracket 5 can be connected to the top surface inside the housing 1 so as to stably support the outdoor fan 4 inside the fan compartment 120 of the housing 1.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments, the outdoor fan 4 may include a drive motor 41 and an impeller 42. The drive motor 41 is fixed on the motor bracket 5, and the impeller 42 is connected to the output shaft of the drive motor 41. The impeller 42 may be arranged opposite to the air outlet 13. The drive motor 41 can drive the impeller 42 to rotate inside the fan housing 120. The airflow generated by the rotation of the impeller 42 can draw outdoor air into the fan housing 120 through the air inlet 12, exchange heat with the outdoor heat exchanger 2, and then discharge it into the outdoor space through the air outlet 13.

[0063] Figure 4 yes Figure 3 The front view.

[0064] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, at least two sets of outdoor fans 4 can be provided. Providing multiple sets of outdoor fans 4 can increase the air volume and improve the heat exchange efficiency of the outdoor heat exchanger 2. At least two sets of outdoor fans 4 can be arranged sequentially at intervals along the height direction of the motor bracket 5, thereby reducing the required size of the casing 1 in the width direction.

[0065] In some embodiments, the motor bracket 5 may include a first vertical rod 51 and a second vertical rod 52. The first vertical rod 51 may extend along the height direction of the housing 1, and the second vertical rod 52 may extend along the height direction of the housing 1. The first vertical rod 51 and the second vertical rod 52 may be arranged parallel to each other at intervals. An outdoor fan 4 is disposed on one side of the first vertical rod 51 and the second vertical rod 52. For example, the outdoor fan 4 is fixedly disposed on the front side of the first vertical rod 51 and the second vertical rod 52, and the outdoor heat exchanger 2 may be disposed at intervals on the back side of the first vertical rod 51 and the second vertical rod 52.

[0066] In some embodiments, the motor bracket 5 may include a base plate 53. The base plate 53 is fixed to the inner bottom surface of the housing 1. The bottom ends of the first vertical rod 51 and the second vertical rod 52 are respectively connected to the base plate 53. The bottom ends of the first vertical rod 51 and the second vertical rod 52 can be fixed inside the housing 1 by the base plate 53, so that the first vertical rod 51 and the second vertical rod 52 are arranged vertically inside the fan compartment 120 of the housing 1.

[0067] In some embodiments, the motor bracket 5 may include a top plate 54. The top plate 54 is fixed to the inner top surface of the housing 1. The top ends of the first vertical rod 51 and the second vertical rod 52 are respectively connected to the top plate 54. The top ends of the first vertical rod 51 and the second vertical rod 52 can be fixed inside the housing 1 by the top plate 54, so that the first vertical rod 51 and the second vertical rod 52 are arranged vertically inside the fan compartment 120 of the housing 1.

[0068] In some embodiments, a plurality of outdoor fans 4 may be disposed in the area between the top plate 54 and the bottom plate 53. The drive motors 41 of the plurality of outdoor fans 4 may be arranged sequentially and at intervals along the height direction on the first vertical rod 51 and the second vertical rod 52.

[0069] Figure 5 yes Figure 3 A partial structural diagram. Figure 6 yes Figure 5 Side view. Figure 7 yes Figure 5 A schematic diagram of its decomposed structure.

[0070] like Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, the outdoor unit of the air conditioner may include a reactor assembly 7. The reactor assembly 7 includes a housing 70 and a reactor 73 disposed within the housing 70. The reactor 73 in the reactor assembly 7 can perform functions such as filtering, stabilizing current and voltage, improving power factor, or suppressing surge current.

[0071] In some embodiments, the reactor assembly 7 may be housed within the fan shroud 120. The reactor assembly 7 may also be mounted on the motor bracket 5. The motor bracket 5 provides installation space for the reactor assembly 7. By placing the reactor assembly 7 within the fan shroud 120, heat dissipation of the reactor assembly 7 can be improved, thus solving the heat dissipation problem of the reactor 73.

[0072] In some embodiments, the reactor assembly 7 can be located in the interval area between two adjacent outdoor fans 4. That is, the reactor assembly 7 can be installed and fixed on the motor bracket 5 in the interval area between adjacent outdoor fans 4. The motor bracket 5 in the interval area between adjacent outdoor fans 4 provides installation space for the reactor assembly 7, which can improve the space utilization of the fan hopper 120 and also prevent the reactor assembly 7 from contacting the outdoor fans 4, thereby improving safety.

[0073] Figure 8 yes Figure 7 A schematic diagram of its decomposed structure.

[0074] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the housing 70 can be mounted on the motor bracket 5. A receiving cavity (not shown) is formed within the housing 70, and the reactor 73 is disposed within this cavity in the housing 1. The housing 70 can extend along the length of the motor bracket 5, allowing the receiving cavity within the housing 70 to extend along the height of the housing 1. In this way, the height space of the receiving cavity within the housing 70 can be expanded using the space of the motor bracket 5 within the fan shroud 120, facilitating the placement of multiple reactors 73 within the housing 70 and solving the problem of accommodating and installing multiple reactors 73.

[0075] In some embodiments, the reactor assembly 7 includes at least two reactors 73, which are arranged sequentially and spaced apart within the housing cavity along the height direction of the housing 1. By arranging multiple reactors 73 sequentially and spaced apart within the housing cavity along the height direction of the housing 1, the space requirement in the width direction of the housing can be reduced, making full use of the height space inside the housing, and thus making full use of the height space of the motor bracket 5. This solves the problem that the compressor compartment 110 of a compact outdoor unit cannot accommodate multiple reactors 73. Furthermore, by extending the housing 70 of the reactor assembly 7 along the height direction of the housing 1 with the motor bracket 5, the width dimension of the housing 70 can be reduced, thereby improving the rainproof performance of the reactor assembly 7.

[0076] Figure 9 yes Figure 7 Another diagram showing the decomposed structure.

[0077] like Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the housing 70 may include a base 71 and an outer cover 72. The base 71 is fixed to the side of the motor bracket 5 away from the outdoor fan 4. For example, the base 71 is disposed on the side of the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4, and is fixedly connected to the first vertical rod 51 and the second vertical rod 52, so that the base 71 can be fixed to the side of the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4. The outer cover 72 may be disposed on the side of the base 71 near the outdoor fan 4, and on the outer periphery of the reactor 73, so that a receiving cavity is formed between the base 71 and the outer cover 72. The reactor 73 may be fixed on the side of the base 71 near the outdoor fan 4, and disposed in the receiving cavity between the base 71 and the outer cover 72, so that the reactor 73 can be disposed between the first vertical rod 51 and the second vertical rod 52. By fixing the base 71 to the side of the motor bracket 5 away from the outdoor fan 4, part of the space on the side of the motor bracket 5 away from the outdoor fan 4 and part of the gap between the first vertical rod 51 and the second vertical rod 52 can be used. This allows the reactor assembly 7 to be fixed on the motor bracket 5, and the outdoor fan 4 to dissipate heat from the reactor 73 nearby, thus solving the heat dissipation problem of the reactor 73. It also increases the distance between the outer casing 72 and the impeller 42 of the outdoor fan 4, avoiding affecting the normal rotation of the impeller 42 and solving the installation problem of the reactor 73.

[0078] In some embodiments, the base 71 may be located on the side of the space between the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4. Thus, when the outer cover 72 is installed on the side of the base 71 near the outdoor fan 4, at least a portion of the outer cover 72 may be arranged within the space between the first vertical rod 51 and the second vertical rod 52. When the reactor 73 is fixed to the side of the base 71 near the outdoor fan 4, at least a portion of the reactor 73 may also be arranged within the space between the first vertical rod 51 and the second vertical rod 52. In this way, the space between the first vertical rod 51 and the second vertical rod 52 can be fully utilized to arrange the reactor assembly 7, allowing the housing 70 to extend along the height direction of the casing 1 within the space between the first vertical rod 51 and the second vertical rod 52, thereby installing multiple reactors 73 within the housing 70 and effectively solving the problem of accommodating and installing multiple reactors 73. Figure 10 yes Figure 5 A schematic diagram of the structure of the reactor assembly 7.

[0079] like Figure 7 , Figure 8 and Figure 10As shown, in some embodiments, a first fixing wall 714 may be provided on one side of the base 71, extending along the height direction of the motor bracket 5. A second fixing wall 715 may be provided on the other side of the base 71, extending along the height direction of the motor bracket 5. The first fixing wall 714 and the second fixing wall 715 may be respectively provided on opposite sides of the base 71. The first fixing wall 714 may be fixed to the first vertical rod 51, for example, the first fixing wall 714 may be fixed to the side of the first vertical rod 51 away from the impeller 42. The second fixing wall 715 may be fixed to the second vertical rod 52, for example, the second fixing wall 715 may be fixed to the side of the second vertical rod 52 away from the impeller 42. By cooperating with the first fixing wall 714 and the second fixing wall 715, the base 71 can be stably fixed to the side of the space between the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4, making full use of the space between the first vertical rod 51 and the second vertical rod 52, thus solving the problem of accommodating and installing the reactor 73 and the outer casing 72.

[0080] Figure 11 yes Figure 10 A schematic diagram of its decomposed structure.

[0081] like Figure 6 , Figure 8 and Figure 11 As shown, in some embodiments, a receiving groove 710 is recessed on the side of the base 71 facing the gap between the first vertical rod 51 and the second vertical rod 52. The receiving groove 710 is located on the side of the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4. The receiving groove 710 can be arranged opposite to and connected to the gap between the first vertical rod 51 and the second vertical rod 52. The reactor 73 can be arranged in the receiving groove 710, and the outer cover 72 can be disposed in the receiving groove 710 and the gap. By connecting the receiving groove 710 of the base 71 with the gap between the first vertical rod 51 and the second vertical rod 52, the space inside the base 71 and the outer cover 72 can be shifted away from the outdoor fan 4. This helps to increase the distance between the housing 70 and the impeller 42 of the outdoor fan 4, avoids affecting the normal rotation of the impeller 42, and makes full use of the space of the receiving groove 710 and the gap, thus solving the problem of accommodating and installing the reactor 73 and the outer cover 72.

[0082] In some embodiments, the receiving groove 710 extends along the height direction of the housing 1, and at least two reactors 73 are arranged sequentially and spaced apart within the receiving groove 710 along the height direction of the housing 1. By extending the receiving groove 710 along the height direction of the housing 1, the height space of the motor bracket 5 can be used to provide installation space for the reactors 73, so that multiple reactors 73 are arranged sequentially and spaced apart within the receiving groove 710 along the height direction of the housing 1.

[0083] like Figure 4, Figure 10 and Figure 11 As shown, in some embodiments, the width of the outer cover 72 is smaller than the distance between the first vertical rod 51 and the second vertical rod 52, so that the outer cover 72 can pass through the gap between the first vertical rod 51 and the second vertical rod 52 and then be connected to the base 71. By setting the width of the outer cover 72, the outer cover 72 can be arranged in the gap between the first vertical rod 51 and the second vertical rod 52, which facilitates the outer cover 72 passing through the gap between the first vertical rod 51 and the second vertical rod 52 and being connected to the base 71. This fully utilizes the gap between the first vertical rod 51 and the second vertical rod 52 and solves the problem of accommodating and installing the outer cover 72 and the reactor 73.

[0084] like Figure 6 As shown, in some embodiments, the outer cover 72 protrudes from the first vertical rod 51 and the second vertical rod 52, and the thickness of the second vertical rod 52 is less than the thickness of the base 71. This allows most of the volume of the outer cover 72 to be accommodated in the space between the first vertical rod 51 and the second vertical rod 52, as well as in the receiving groove 710 of the base 71. This helps to increase the distance between the outer cover 72 and the impeller 42 of the outdoor fan 4, avoiding interference with the normal rotation of the impeller 42. It also makes full use of the space between the receiving groove 710 and the space between the first vertical rod 51 and the second vertical rod 52, thus solving the problem of accommodating and installing the reactor 73 and the outer cover 72.

[0085] Figure 12 yes Figure 10 A sectional view.

[0086] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the outer wall of the outer cover 72 is provided with heat dissipation holes 721, which are connected to the accommodating cavity inside the outer cover 72. The heat generated by the reactor 73 in the accommodating cavity can be discharged to the outside of the housing 70 through the heat dissipation holes 721.

[0087] In some embodiments, the reactor assembly 7 may include a waterproof cover 74, which covers the outer wall of the outer casing 72 and extends to the outside of the heat dissipation hole 721. A heat dissipation channel 740 may be formed between the waterproof cover 74 and the outer wall of the outer casing 72, the heat dissipation channel 740 connecting to the ventilation chamber 120, and the heat dissipation hole 721 connecting the accommodating cavity and the heat dissipation channel 740. Thus, the accommodating cavity can be connected to the ventilation chamber 120 through the heat dissipation hole 721 and the heat dissipation channel 740, allowing heat in the accommodating cavity to be discharged to the ventilation chamber 120 outside the housing 70 through the heat dissipation hole 721 and the heat dissipation channel 740. Air in the ventilation chamber 120 can also enter the accommodating cavity inside the housing 70 through the heat dissipation channel 740 and the heat dissipation hole 721, thereby achieving heat dissipation of the reactor 73 inside the housing 70 and improving the heat dissipation efficiency of the reactor 73.

[0088] In some embodiments, the outer cover 72 may be made of metal, so that the heat of the reactor 73 inside the housing 70 can also be exchanged through the surface of the outer cover 72 with the cold air inside the fan compartment 120, thereby further improving the heat dissipation efficiency of the reactor 73.

[0089] like Figure 12 As shown, in some embodiments, the outer casing 72 may have multiple heat dissipation holes 721, which may be arranged sequentially at intervals along the height direction of the outer casing 72. The heat dissipation channel 740 may extend along the height direction of the outer casing 72, and its upper and lower ends are respectively connected to the ventilation chamber 120. Thus, the upper and lower ends of the heat dissipation channel 740 can flow with the air inside the ventilation chamber 120, forming a cooling airflow within the heat dissipation channel 740. This cooling airflow can enter the interior of the housing 70 through the heat dissipation holes 721, dissipating heat from the accommodating cavity and the reactor 73. This cooling airflow can also draw air and heat from the accommodating cavity, thereby dissipating heat from the reactor 73.

[0090] It should be noted that in some other embodiments, a plurality of heat dissipation holes 721 may also be arranged horizontally at intervals on the side wall of the outer casing 72. In this case, the heat dissipation channel 740 may also be arranged extending horizontally.

[0091] like Figure 12 As shown, in some embodiments, a rainproof wall 722 extending outwardly and downward is provided on the top edge of the heat dissipation hole 721, and the rainproof wall 722 is located inside the heat dissipation channel 740. By obliquely shielding the outside of the heat dissipation hole 721 with the rainproof wall 722, when rainwater enters from the top opening of the heat dissipation channel 740, it can flow downward along the rainproof wall 722, preventing rainwater entering the heat dissipation channel 740 from entering the housing 70 through the heat dissipation hole 721, thereby improving the rainproof performance of the reactor assembly 7.

[0092] like Figure 12 As shown, in some embodiments, multiple sets of heat dissipation holes 721 can be provided on the outer cover 72, and these multiple sets of heat dissipation holes 721 can be provided in different areas of the outer wall of the outer cover 72. The heat dissipation hole groups can be provided on the side wall corresponding to the reactor 73, and a waterproof cover 74 can be provided on the outside of each heat dissipation control group to ensure the rainproof performance of the heat dissipation control group.

[0093] In some embodiments, a set of heat dissipation holes may be provided on the side walls of the outer casing 72 on opposite sides of the reactor 73. The two sets of heat dissipation holes can respectively allow air to enter or exit through the heat dissipation holes 721. For example, when one set of heat dissipation holes introduces air from the fan compartment 120 into the accommodating cavity inside the casing, the air in the accommodating cavity can be discharged outside the casing through the other set of heat dissipation holes and the corresponding heat dissipation channel 740, thereby achieving air circulation within the accommodating cavity inside the casing and improving the heat dissipation efficiency of the reactor 73.

[0094] It should be noted that, in some embodiments, a set of heat dissipation holes can be provided on the side walls of each reactor 73 on opposite sides. In this way, by using two sets of heat dissipation holes as a group, multiple sets of heat dissipation holes can dissipate heat from the multiple reactors 73 within the reactor assembly 7, ensuring the heat dissipation efficiency of the multiple reactors 73.

[0095] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the side of the waterproof cover 74 closest to the base 71 can be disposed within the receiving groove 710. Thus, when the waterproof cover 74 is mounted on the base 71 along with the outer cover 72, the waterproof cover 74 and the heat dissipation channel 740 can be located between the first vertical rod 51 and the second vertical rod 52. Utilizing the space between the first vertical rod 51 and the second vertical rod 52 of the motor bracket 5 to install the waterproof cover 74 and the heat dissipation channel 740 avoids contact between the waterproof cover 74 and the impeller 42 of the outdoor fan 4, thereby improving space utilization and safety.

[0096] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the outer wall of the outer casing 72 may be provided with a cable outlet hole 723, through which the connecting wires of the reactor 73 inside the housing 70 can be led out of the housing 70. The side wall of the base 71 may be provided with a cable passage hole 716, which is arranged opposite to and communicates with the cable outlet hole 723. In this way, the connecting wires of the reactor 73 inside the housing 70 can be led out of the housing 70 sequentially through the cable outlet hole 723 and the cable passage hole 716. It should be noted that in other embodiments, the cable outlet hole 723 may also be directly on the base 71.

[0097] In some embodiments, the outlet hole 723 is located on the side wall of the outer casing 72 in the region between two adjacent reactors 73, so that the connecting wires of the reactors 73 on both sides of the outlet hole 723 can be led out through the outlet hole 723, which helps to reduce the number of outlet holes 723 and improve the sealing of the housing 70. In addition, when there are three or more reactors 73 in the housing 70, multiple outlet holes 723 can be provided, and multiple outlet holes 723 can be respectively provided on the side wall of the outer casing 72 in the region between two adjacent reactors 73.

[0098] like Figure 2 , Figure 6 and Figure 10As shown, in some embodiments, the wire passage hole 716 can be located on the side of the first vertical rod 51 and the second vertical rod 52 away from the outdoor fan 4. In this way, after the connecting wire of the reactor 73 is led out through the wire passage hole 716, it can be arranged in the back area of ​​the motor bracket 5, which can increase the distance between the connecting wire of the reactor 73 and the impeller 42 of the outdoor fan 4, and prevent the impeller 42 from contacting the connecting wire of the reactor 73 when rotating.

[0099] In some embodiments, the cable outlet 723 of the outer cover 72 can be located on the side wall of the outer cover 72 near the compressor chamber 110. The cable passage hole 716 on the base 71 can also be located on the side wall of the base 71 near the compressor chamber 110. In this way, the connecting wire of the reactor 73 can be easily led out through the cable outlet hole 723 and the cable passage hole 716, and then introduced into the compressor chamber 110 through the partition 11, thereby facilitating connection with the electrical control box 6. This helps to shorten the length of the connecting wire and avoids excessively long and messy wiring in the fan compartment 120.

[0100] Figure 13 yes Figure 11 Schematic diagram of the middle section. Figure 14 yes Figure 13 The front view. Figure 15 yes Figure 13 A schematic diagram of the structure of the middle base 71.

[0101] like Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the base 71 may include a mounting plate 711 and a first side plate 712 and a second side plate 713 disposed on opposite sides of the mounting plate 711. The mounting plate 711 may be arranged vertically. The first side plate 712 and the second side plate 713 may extend along the side edges in the height direction of the mounting plate 711. A receiving groove 710 may be formed between the mounting plate 711, the first side plate 712, and the second side plate 713. A first fixing wall 714 may extend from the first side plate 712 in a direction away from the second side plate 713. A second fixing wall 715 may extend from the second side plate 713 in a direction away from the first side plate 712.

[0102] Figure 16 yes Figure 15 The front view.

[0103] like Figure 14 and Figure 16 As shown, in some embodiments, a support portion 717 may be provided on the wall of the receiving groove 710, and the support portion 717 may be provided on the mounting plate 711. The bottom of the reactor 73 may be mounted and fixed on the support portion 717. There may be two support portions 717, or multiple support portions 717 arranged at left and right intervals. The left and right ends of the bottom of the reactor 73 may be fixed to a support portion 717 respectively.

[0104] In some embodiments, a support groove may be provided in the support portion 717, and the bottom of the reactor 73 may be engaged in the support groove, thereby being fixedly supported on the support portion 717.

[0105] like Figure 14 and Figure 16 As shown, in some embodiments, the receiving groove 710 may have a fixing hole 718 on its groove wall, and the fixing hole 718 may be provided on the mounting plate 711. The fixing hole 718 is located above the support portion 717. The reactor 73 has a positioning hole 731 arranged opposite to the fixing hole 718. The reactor 73 can be fixed in the receiving groove 710 by screws passing through the positioning hole 731 and the fixing hole 718.

[0106] In some embodiments, the reactor 73 may be provided with a plurality of positioning holes 731, which may be divided into two groups and respectively located at the upper and lower ends of the reactor 73. This facilitates the inverted installation of the reactor 73. Whether installed upright or inverted, a set of positioning holes 731 can be arranged corresponding to the fixing holes 718, which can facilitate the fixing of the reactor 73 in the receiving groove 710.

[0107] like Figure 14 As shown, in some embodiments, one of two adjacent reactors 73 can be installed upright and the other can be installed upside down, such that the terminals 732 of the two adjacent reactors 73 are arranged facing each other, so that the connecting wires of the two adjacent reactors 73 can be led out from the same outlet hole 723.

[0108] like Figure 11 Figure 14 As shown, in some embodiments, the outer cover 72 may have a protruding bulge 725 in the middle. A clearance groove may be formed inside the outer cover 72 on the inner side of the bulge 725. The terminals 732 of two adjacent reactors 73 can be accommodated in the clearance groove inside the bulge 725, which helps to reduce the thickness of the outer cover 72, reduce the thickness of the outer cover 72 protruding from the first vertical rod 51 and the second vertical rod 52, and increase the distance between the outer cover 72 and the impeller 42 of the outdoor fan 4. Furthermore, the bulge 725 may be located in the area between the impellers 42 of the two sets of outdoor fans 4, avoiding contact between the bulge 725 and the impeller 42.

[0109] like Figure 4 , Figure 10 and Figure 11As shown, in some embodiments, the outer cover 72 has fixing portions 724 on opposite sides. The fixing portions 724 can be fixed to the wall of the receiving groove 710, thereby connecting the outer cover 72 to the base 71 and covering it. The fixing portions 724 may have fixing holes, and the mounting plate 711 of the base 71 may have screw holes arranged opposite to the fixing holes of the fixing portions 724. When the outer cover 72 is placed on the base 71, and the fixing holes of the fixing portions 724 are aligned with the screw holes on the mounting plate 711, the outer cover 72 can be fixed to the base 71 with screws.

[0110] like Figure 4 and Figure 14 As shown, in some embodiments, the top of the mounting plate 711 of the base 71 may be provided with a hanging rib 719, which extends toward the outer cover 72. When the outer cover 72 is installed, the outer cover 72 covers the mounting plate 711 of the base 71, and the top of the outer cover 72 can be hooked onto the hanging rib 719, which facilitates the pre-fixing of the outer cover 72. This makes it easier for the fixing holes of the fixing part 724 to align with the screw holes on the mounting plate 711, thereby making it easier for the installer to fix the screws on the fixing part 724, and thus install and fix the outer cover 72 onto the base 71.

[0111] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
