[0084] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0085] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0086] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0087] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0088] As shown in FIG. 1 to FIG. 23 , according to an embodiment of the present application, a HVAC equipment outdoor unit 100 is proposed. The HVAC equipment outdoor unit 100 includes a housing 20 , a heat exchanger 40 , a top cover assembly 10 and an electric control box assembly 30 .

[0089] Specifically, the top cover assembly 10 and the electric control box assembly 30 are respectively installed on the box body 20, and the heat exchanger 40 is installed inside the box body. At this time, the top cover assembly 10 is connected to the top of the box body and is located above the heat exchanger. The blades 13 of the top cover assembly 10 are located above the heat exchanger 40. At this time, the blades 13 are located on the outside of the heat exchanger 40. The electric control box assembly 30 has a heat dissipation duct 301. One end of the heat dissipation duct 301 is connected to the outside, and the other end of the heat dissipation duct 301 is connected to the inside of the box body 20. The blades 13 can rotate, and the rotation of the blades 13 drives the airflow, so that the external airflow can enter the interior of the box body 20 through the heat dissipation duct 301, and at the same time, the airflow inside the box body 20 can be discharged to the outside through the top cover assembly 10.

[0090] In the prior art, the heat exchanger 40 is disposed radially outside the blades 13. In this case, the diameter of the blades 13 is limited by the structural shape of the heat exchanger 40. In this case, the driving ability of the blades 13 on the airflow is limited.

[0091] In an embodiment of the present application, as shown in Figures 2 and 16, the blades 13 are arranged above the heat exchanger 40, that is, the blades 13 are arranged on the outside of the heat exchanger 40, so that the size of the blades 13 is not limited by the structural size of the heat exchanger 40. By increasing the size of the blades 13, the driving ability of the blades 13 on the airflow is improved, thereby reducing the problem of airflow stagnation areas in the HVAC equipment outdoor unit 100, and effectively improving the heat exchange effect of the HVAC equipment outdoor unit 100. At the same time, the interior of the box body 20 can be connected to the outside world through the heat dissipation duct 301 of the electrical control box assembly 30. Driven by the blades 13, the airflow can enter the heat dissipation duct 301 to achieve heat dissipation of the electrical control box assembly 30, further reducing the problem of airflow stagnation areas in the HVAC equipment outdoor unit 100.

[0092] It should be noted that in the embodiments of the present application, the electrical control box assembly 30 is used to control the HVAC equipment outdoor unit 100, where the control methods include but are not limited to power on, power off, and operating mode switching. The electrical control box assembly generates heat during operation. If the electrical control box assembly 30 is not effectively cooled, the electrical control box assembly 30 may malfunction due to excessive temperature, thereby affecting the operation of the HVAC equipment outdoor unit 100.

[0093] In some embodiments of the present application, the top cover assembly 10 includes an air scoop 15 and a top cover body 14 having a receiving space. The top of the housing 20 is connected to the top cover body 14. The air scoop 15 is disposed within the receiving space and is fixedly connected to the top cover body 14. The blades 13 are disposed within an air guide channel 155 of the air scoop 15.

[0094] Specifically, the top cover assembly 10 includes an air scoop 15, blades 13, and a top cover body 14 having a receiving space. The top cover body 14 is disposed outside the housing 20 and is fixedly connected to the top of the housing 20. The air scoop 15 is disposed within the receiving space of the top cover body 14. The blades 13 are disposed within an air guide channel 155 of the air scoop 15 and are rotatable relative to the air guide channel 155. The outside world can communicate with the heat exchanger 40 through the air guide channel 155.

[0095] As shown in Figures 1 and 3, by setting the top cover body 14 on the top of the box body 20, the heat exchanger 40 is set inside the box body 20. At this time, the top cover body 14 is located on the outside of the heat exchanger 40, the air guide cover 15 is set in the receiving space of the top cover body 14, and the blades 13 are set in the air guide channel 155 of the air guide cover 15. At this time, the blades 13 are set on the outside of the heat exchanger 40, so that the size of the blades 13 is not limited by the structural size of the heat exchanger 40. By increasing the size of the blades 13, the driving ability of the blades 13 on the airflow is improved, thereby reducing the problem of airflow stagnation area in the HVAC equipment outdoor unit 100, so that the heat exchange effect of the HVAC equipment outdoor unit 100 is effectively improved.

[0096] It should be understood that the air guide channel 155 has an air inlet and an air outlet. When the blade 13 rotates in the air guide channel 155, it can drive the airflow, so that the airflow enters the air guide channel 155 through the air inlet, and the airflow in the air guide channel 155 is discharged from the air guide channel 155 through the air outlet.

[0097] It should be noted that when the blades 13 rotate, driven by the blades 13, the airflow direction can be from the heat exchanger 40 to the blades 13, or the airflow direction can be from the blades 13 to the heat exchanger 40. In the embodiment of the present application, the airflow direction is from the heat exchanger 40 to the blades 13, that is, the airflow at the heat exchanger 40 is extracted by the rotation of the blades 13, so that the airflow that has undergone heat exchange with the heat exchanger 40 is extracted and the airflow that has not undergone heat exchange flows to the heat exchanger 40, thereby achieving heat exchange between the flowing airflow and the heat exchanger 40.

[0098] In addition, the blades 13 can be metal or non-metal. In the embodiment of the present application, the blades 13 are non-metallic, such as plastic or carbon fiber, and can be manufactured in an integrated manner, thereby improving processing efficiency.

[0099] It should be pointed out that, as shown in Figure 3, an air guide cover 15 is provided, and the blades 13 are provided in the air guide channel 155 of the air guide cover 15, so that the blades 13 can rotate in a relatively small space, so that the blades 13 can increase the negative pressure formed during the rotation of the blades 13 under the same rotation speed conditions, thereby improving the driving ability of the airflow, so that the flow rate of the airflow is increased.

[0100] In addition, as shown in FIG3 , an air guide cover 15 is provided to wrap the blades 13 , thereby reducing the noise transmitted outward during the rotation of the blades 13 , thereby effectively reducing the noise during the operation of the HVAC equipment outdoor unit 100 .

[0101] In the present application, the HVAC equipment outdoor unit 100 also includes a compressor assembly and an electrical control box assembly 30, wherein the compressor assembly is arranged in the box body 20, the heat exchanger 40 is arranged around the circumference of the compressor assembly, and the electrical control box assembly 30 is installed on the box body 20 and electrically connected to the compressor assembly to control the operation of the compressor assembly.

[0102] In some embodiments of the present application, as shown in Figures 3 and 4 , the top cover body 14 is provided with a top surface and a first communication port 143, with the top surface facing away from the first communication port 143. One end of the air guide channel 155 of the air guide cover 15 is connected to the first communication port 143. The top of the housing 20 of the HVAC equipment outdoor unit 100 is plugged into and mated with the first communication port 143.

[0103] Specifically, the first communication port 143 of the top cover body 14 is plugged into the top of the housing 20 of the HVAC outdoor unit 100. This plug-in connection method is simple in structure, effectively optimizes the structure, and effectively reduces manufacturing costs. In addition, the plug-in connection method facilitates assembly, effectively improves production efficiency, and effectively reduces production costs.

[0104] It should be noted that the top of the box body 20 and the first communication port 143 are plugged into each other, wherein the top of the box body 20 can be inserted into the first communication port 143, or the first communication port 143 can be inserted into the top of the box body.

[0107] Specifically, a second connecting port 144 is provided on the top cover body 14 so that the box body 20 is connected to the outside through the first connecting port 143 and the second connecting port 144, thereby enabling the external air flow to exchange heat with the working parts inside the box body 20, thereby meeting the normal operation requirements of the HVAC equipment outdoor unit 100.

[0108] It should be understood that the first connecting port 143 and the second connecting port 144 are opened on opposite sides of the top cover body 14, so that the airflow can flow in a straight line when flowing in the top cover body 14, reducing the impact on the airflow velocity and improving the heat exchange efficiency of the HVAC equipment outdoor unit 100.

[0109] It should be pointed out that the top of the box body 20 of the HVAC equipment is an open structure, and the first connecting port 143 is connected to the open structure on the top of the box body 20. The interior of the box body 20 is connected to the outside world through the first connecting port 143, the interior of the top cover body 14 and the second connecting port 144.

[0111] In addition, the flow cross-section area of ​​the first communication port 143 and the flow cross-section area of ​​the second communication port 144 may be equal to or different from each other.

[0112] In some embodiments of the present application, the top cover assembly 10 further includes a mesh cover 11 mounted on the top cover body 14, wherein the second communication port 144 on the top cover body 14 is shielded by the mesh cover 11. By providing the mesh cover 11 at the second communication port 144, the second communication port 144 is shielded while enabling airflow exchange between the second communication port 144 and the outside world, thereby reducing the possibility of external foreign matter falling into the interior of the top cover body 14 and the interior of the box body 20 through the second communication port 144.

[0113] It should be noted that the mesh cover 11 is connected and fixed to the top cover body 14, and the connection and fixing methods include but are not limited to screw connection, clamping, snap connection, riveting, bonding, welding, etc.

[0114] In addition, the mesh cover 11 can be a metal part, which can be processed by welding or casting; the mesh cover 11 can also be a non-metallic part, such as plastic, which can be formed in one step by injection molding.

[0115] In addition, the mesh cover 11 has mesh holes, and the shapes of the mesh holes include but are not limited to circle, square, pentagon, hexagon, triangle, ellipse, diamond, etc.

[0116] In some embodiments of the present application, as shown in Figures 6 and 10, the side of the top cover body 14 facing away from the first connecting port 143 is a top surface, and a groove 145 is provided on the top surface, wherein a second connecting port 144 is provided on the bottom surface of the groove 145, and the first connecting port 143 and the second connecting port 144 are arranged opposite to each other, and at least part of the body of the mesh cover 11 is accommodated in the groove 145 in the direction from the first connecting port 143 to the second connecting port 144, and is abutted against the bottom surface of the groove 145.

[0117] Specifically, the shape of the groove 145 is adapted to the shape of the mesh cover 11 . The groove 145 is provided and the mesh cover 11 is limited by the groove 145 , thereby achieving positioning and installation of the mesh cover 11 , thereby improving the installation accuracy of the mesh cover 11 .

[0118] It should be understood that, in the direction from the first communicating opening 143 to the second communicating opening 144 , the mesh cover 11 may be partially disposed in the receiving groove, or the entire body may be disposed in the receiving groove.

[0119] In addition, a groove 145 is provided on the top surface of the top cover body 14 . By utilizing the structural change, the strength of the top cover body 14 is further enhanced, thereby further improving the overall structural strength of the top cover body 14 .

[0120] It should be noted that a reinforcing rib 1422 is provided on the bottom surface of the groove 145. The reinforcing rib 1422 can increase the strength of the bottom surface, thereby increasing the overall strength of the top cover assembly 10. In addition, the reinforcing rib 1422 includes but is not limited to a rib plate, a protruding structure, or a recessed structure.

[0121] In some embodiments of the present application, as shown in Figures 3 and 5, the top cover assembly 10 further includes a driving member 12. The mesh cover 11 of the top cover assembly 10 has a side surface facing the second communication port 144, and the driving member 12 is mounted and fixed on the side surface. The blades 13 are connected to the drive shaft of the driving member 12 and are rotatably disposed within the air guide channel 155 of the air guide cover 15.

[0122] Specifically, when the HVAC equipment outdoor unit 100 is running, the driving member 12 rotates and drives the blades 13 to rotate. During the rotation of the blades 13, the air flow flows from the first connecting port 143 to the second connecting port 144, or the air flow flows from the second connecting port 144 to the first connecting port 143. The air flow is driven by the blades 13 and the driving member 12, thereby improving the heat exchange efficiency of the HVAC equipment outdoor unit 100.

[0123] Furthermore, the mesh cover 11 is installed in the groove 145 at the top of the top cover body 14, and the groove 145 is used to limit the installation position of the mesh cover 11, thereby limiting the installation position of the blade 13 and reducing the noise generated by the blade 13 during operation due to vibration and other reasons.

[0124] It should be understood that, in the application, the blades 13 and the driving member 12 form an axial flow fan structure, that is, the airflow is introduced and discharged along the axial direction of the blades 13. In addition, in the application, driven by the blades 13 and the driving member 12, the airflow flows from one side of the first connecting port 143 to the other side of the second connecting port 144.

[0125] It should be noted that, in the application, the connection methods between the driving member 12 and the mesh cover 11 include but are not limited to screw connection, snap connection, bonding, welding, riveting, etc. At the same time, the blade 13, the first communication port 143, and the second communication port 144 are coaxially arranged.

[0126] In addition, the driving member 12 includes but is not limited to an electric motor or a starter motor.

[0127] In some embodiments of the present application, the top cover body 14 is an integrated structure, and the top cover body 14 of the integrated structure is integrally formed and manufactured.

[0128] In some embodiments of the present application, as shown in Figures 14 and 15, the top cover body 14 is a split structure, including a side panel 142 and a corner panel 141, wherein the number of side panel 142 is at least one, and the number of corner panel 141 is at least one, and the at least one side panel 142 forms a cylindrical structure with openings at both ends of the cylindrical structure, one of the two openings of the cylindrical structure is a first connecting port 143, and the corner panel 141 is installed at the transition position of the other opening of the cylindrical structure, and the corner panel 141 and the side panel 142 are combined to form a second connecting port 144.

[0129] By splitting the top cover body 14 into two parts, namely the side panel 142 and the angle panel 141 , the difficulty of processing can be reduced, thereby reducing the manufacturing cost, and at the same time, the yield rate of the top cover body 14 can be improved.

[0130] It should be pointed out that the corner plate 141 is a bent part, and the bending direction is bent toward the inner side of the top cover body 14. After the corner plate 141 is installed on the side plate 142 with a cylindrical structure, the bent position of the corner plate 141 constitutes a part of the groove 145 for accommodating the mesh cover 11.

[0131] When the number of the side plate 142 is one, the side plate 142 is bent and the two free ends of the bent side plate are connected and fixed by bonding or welding to form a cylindrical structure.

[0132] When there are two or more side panels 142, all side panels 142 are assembled (the assembly locations may be connected by, but are not limited to, screws, adhesives, rivets, snap-fit ​​connections, or welding), thereby forming a cylindrical structure. Providing multiple side panels 142 allows the structure to be further disassembled, further reducing the difficulty of the manufacturing process.

[0133] In addition, when the number of the angle plate 141 is one, the angle plate 141 is provided only at one corner position of the other opening of the cylindrical structure (the opening facing away from the first communication port 143 ).

[0134] When there are multiple (two or more) angle plates 141 , one angle plate 141 is provided at each corner position of the other opening of the cylindrical structure (the opening facing away from the first communication port 143 ).

[0135] In some embodiments of the present application, the side panels 142 of the top cover body 14 form a cylindrical structure having two openings arranged opposite to each other, one of which constitutes a first connecting port 143 of the top cover body 14, and the other opening is provided with a flange 1423, and the corner panel 141 of the top cover body 14 is arranged at the corner position of the other opening of the cylindrical structure and is connected and fixed to the flange 1423.

[0136] By providing the flange 1423 , the contact area between the side panel 142 and the angle panel 141 is increased, so that the connection strength between the angle panel 141 and the side panel 142 is enhanced, further improving the overall structural strength of the top cover body 14 .

[0137] In some embodiments of the present application, as shown in Figures 7 to 9, the air guide cover 15 includes a main body 151 and a shielding portion 152. The main body 151 is configured as a cylindrical structure, and the air guide channel 155 is opened along the axial direction of the cylindrical structure, and the air guide channel 155 is connected to the opposite ends of the cylindrical structure. The shielding portion 152 is connected to the outer peripheral surface of the main body 151, and the shielding portion 152 is corresponding to the corner position of the top cover body 14 of the cylindrical structure, and each corner position is respectively provided with a shielding portion 152, and the space between the top cover body 14 of the cylindrical structure and the main body 151 is blocked by the shielding portion 152.

[0138] Specifically, the top cover body 14 is a cylindrical structure, and the radial cross-section of the cylindrical structure is a rectangular structure, so that the structural strength and stability of the top cover body 14 can be improved. At this time, the top cover body 14 has four corners, and the number of the shielding parts 152 in this application is also four. The four shielding parts 152 are arranged at circumferential intervals along the outer peripheral surface of the main body 151 of the cylindrical structure, and each corner of the top cover body 14 is correspondingly provided with a shielding part 152. By providing the shielding part 152, it is possible to shield the space between the top cover body 14 and the main body 151 of the cylindrical structure, reduce the situation where the airflow enters between the top cover body 14 and the air guide cover 15 (the airflow entering between the two is prone to stagnation), thereby reducing the situation where the airflow exists in the airflow stagnation area in the HVAC equipment outdoor unit 100, and improving the heat exchange effect of the HVAC equipment outdoor unit 100.

[0139] It should be understood that the shielding portion 152 and the main body 151 can be an integral structure or a separate structure. When the shielding portion 152 and the main body 151 are an integral structure, they can be manufactured by an integrated molding method. When the shielding portion 152 and the main body 151 are separate structures, they can be processed separately and then connected and fixed by bonding, screw connection, welding, riveting, or clamping.

[0140] It should be noted that along the axial direction of the cylindrical main body 151, all shielding portions 152 can be located on the same circumferential surface or can be arranged at intervals. In the embodiment of the present application, all shielding portions 152 are located on the same circumferential surface, thereby achieving optimal structural stability of the air guide cover 15 and reducing the shaking of the air guide cover 15 caused by the rotation of the blades 13.

[0141] In addition, the shielding portion 152 may be connected to the inner wall of the top cover body 14 (the inner surface of the receiving space) or may not be connected to each other. When the two are connected, the shielding portion 152 is arranged in a close relationship with the inner wall of the top cover body 14 and is connected by bonding, screwing, welding, riveting or clamping. When the two are not connected, the shielding portion 152 can be arranged in a close relationship with the inner wall of the top cover body 14. At the same time, the shape of the shielding portion 152 is adapted to the shape of the inner wall of the top cover body 14, thereby improving the shielding effect.

[0142] Furthermore, the air guide channel 155 in the air guide cover 15 can be a straight channel or a curved channel. In the embodiment of the present application, the air guide cover 15 has a cylindrical structure, and the two ends of the cylindrical structure are open structures. In this case, the air guide channel 155 is a straight channel structure, one open end of the cylindrical structure is used for air intake, and the other open end of the cylindrical structure is used for air discharge.

[0143] Furthermore, in the axial direction of the blade 13, the size of the air guide channel 155 is greater than or equal to the size of the blade 13, so that the blade 13 can be completely accommodated in the air guide channel 155, thereby further enhancing the driving ability of the blade 13 on the airflow.

[0144] In some embodiments of the application, as shown in FIG9 , a wire hole 156 is provided on the air guide 15 for passing the connecting wire of the driving member 12. The provision of the wire hole 156 facilitates the routing of the connecting wire of the driving member 12, thereby improving the convenience of assembly and thereby effectively improving the efficiency of assembly.

[0145] It should be noted that the wire-passing holes 156 include but are not limited to round holes, square holes, diamond holes, triangular holes, elliptical holes, pentagonal holes or hexagonal holes.

[0146] The wire hole 156 is formed on the side wall of the air scoop 15 and is disposed close to the driving member 12 to reduce the length of the connecting wire in the air guide channel 155 of the air scoop 15 and to reduce the influence of the connecting wire on the air guide channel 155 .

[0147] In some embodiments of the present application, as shown in Figures 7 to 9, the air guide cover 15 also includes a connecting portion 153 connected to the outer peripheral surface of the main body 151, and the shielding portion 152 and the connecting portion 153 are arranged at intervals along the axial direction of the cylindrical structure. The connection method between the top cover body 14 of the cylindrical structure and the inner wall of the connecting portion 153 includes welding, bonding, clamping, riveting or screw connection.

[0148] Specifically, a connecting portion 153 is provided, and the connecting portion 153 is used to connect and fix the air guide cover 15 and the top cover body 14, so that the two become an integral structure, thereby improving the overall strength and reducing the shaking of the blade 13 during rotation due to poor structural strength, thereby improving the stability of the operation of the blade 13, and further effectively improving the heat exchange effect of the HVAC equipment outdoor unit 100.

[0149] In addition, by setting the connection method between the connecting portion 153 and the top cover body 14, the connection method between the two can be set according to specific needs, thereby improving the flexibility of assembly. As a specific embodiment, in this application, the air guide cover 15 is fixed to the top cover body 14 by bonding. The bonding method is convenient for assembly and the connection position has good structural strength, which can effectively meet the needs of use.

[0150] It should be understood that the connection portion 153 and the main body 151 can be an integral structure or a separate structure. When the connection portion 153 and the main body 151 are an integral structure, they can be manufactured by an integrated molding method. When the connection portion 153 and the main body 151 are separate structures, they can be processed separately and then connected and fixed by bonding, screw connection, welding, riveting, or clamping.

[0151] In some embodiments of the present application, as shown in Figures 7 and 8, the air scoop 15 is further provided with a reinforcement portion 154. The reinforcement portion 154 is provided on at least one of the shielding portion 152, the connecting portion 153, the main body 151, the connection between the main body 151 and the connecting portion 153, and the connection between the main body 151 and the shielding portion 152.

[0152] Specifically, the air guide cover 15 is coaxially arranged with the blade 13. By providing the reinforcement portion 154, the overall structural strength of the air guide cover 15 can be improved, so that the stability of the air guide cover 15 can be improved. When the blade 13 rotates relative to the air guide cover 15, the eccentricity of the blade 13 relative to the air guide cover 15 is reduced, so that the stability of the airflow formed by the blade 13 is improved, thereby improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0153] It should be pointed out that in the embodiment of the present application, a reinforcement portion 154 is provided on each of the shielding portion 152, the connecting portion 153, the main body 151, the connection position between the main body 151 and the connecting portion 153, and the connection position between the main body 151 and the shielding portion 152, so as to improve the structural strength of the air guide cover 15 as a whole.

[0154] In addition, the reinforcement parts 154 are dispersedly arranged on the air guide cover 15 , thereby further making the structure of the air guide cover 15 uniform and further improving the overall structural strength of the air guide cover 15 .

[0155] In some embodiments of the present application, the reinforcing portion 154 includes at least one of a groove 145 , a convex ridge, and a rib.

[0156] By configuring the structure of the reinforcement portion 154 , the reinforcement portion 154 can effectively meet the requirements of use. Among them, the groove 145 , the convex bump, and the rib plate can have one structure, two structures, or three structures as the reinforcement portion 154 .

[0157] In an embodiment of the present application, the groove 145 and the rib are both set as a reinforcing structure 1421, that is, a part of the reinforcing structure 1421 is the groove 145, and the other part of the reinforcing structure 1421 is the rib. Through the combination of the two, the overall structure of the air guide cover 15 can be effectively enhanced.

[0158] In some embodiments of the present application, as shown in FIG. 4 to FIG. 6 , FIG. 12 , FIG. 13 , and FIG. 15 , the top cover body 14 is further provided with a reinforcement structure 1421 located between the first communication port 143 and the top surface.

[0159] Specifically, the reinforcement structure 1421 is arranged between the top surface and the first connecting port 143. The distance between the reinforcement structure 1421 and the top surface is greater than the distance between the reinforcement structure 1421 and the first connecting port 143. The first connecting port 143 of the top cover body 14 is plugged into the top of the box body 20 of the HVAC equipment outdoor unit 100. By providing a reinforcement structure 1421 arranged close to the first connecting port 143 on the top cover body 14, the overall structural strength of the top cover assembly 10 is enhanced, thereby improving the structural strength of the connection position between the first connecting port 143 and the box body 20, thereby reducing the situation where the operation of the HVAC equipment outdoor unit 100 is adversely affected by insufficient structural strength of the top cover assembly 10.

[0160] It should be understood that the top of the box body 20 is plugged into the top cover body 14. If the reinforcing structure 1421 is not provided on the top cover body 14, the strength of the top cover body 14 itself is relatively low, especially the connection position between the top cover body 14 and the box body 20. Therefore, a reinforcing structure 1421 is provided on the top cover body 14 and the position of the reinforcing structure 1421 and the first connecting port 143 are provided close to each other, so as to improve the strength and stability of the connection position between the top cover body 14 and the box body 20.

[0161] In addition, the reinforcing structure 1421 refers to a structure formed on the top cover body 14, which can be integrally formed with the top cover body 14, or can be separately processed and then mounted and fixed on the top cover body 14. In the embodiment of the present application, the reinforcing structure 1421 is integrally formed with the top cover body 14, thereby reducing the processing steps and effectively improving the production efficiency.

[0162] It should be noted that by providing the reinforcement structure 1421 on the top cover body 14, the air guide cover 15 is not involved in the weighing. In this case, the material of the air guide cover 15 can be optimized, which not only reduces the mass of the air guide cover 15, but also effectively reduces the manufacturing cost of the air guide cover 15. For example, in the present application, the air guide cover 15 can be provided as a component formed of a plastic or foam material.

[0163] In some embodiments of the present application, the reinforcement structure 1421 is provided on the side plate 142 of the top cover body 14 , and the reinforcement structure 1421 is provided as a protruding structure.

[0164] Specifically, a reinforcement structure 1421 which is a raised structure is formed on the side plate 142 of the top cover body 14, wherein the reinforcement structure 1421 which is a raised structure is formed on the outer surface or the inner surface of the top cover body 14. When the raised structure is formed on the outer surface of the top cover body 14, it can be a convex structure formed on the outer surface of the top cover body 14, or it can be a raised structure formed by bulging from the inner surface of the top cover body 14 to the outer surface; when the raised structure is formed on the inner surface of the top cover body 14, it can be a convex structure formed on the inner surface of the top cover body 14, or it can be a raised structure formed by bulging from the outer surface to the inner surface of the top cover body 14.

[0165] In addition, the reinforcing structure 1421 of the raised structure is arranged near the first connecting port 143 of the top cover body 14, wherein, when the raised structure is formed by a bulging manner, the top of the box body 20 and the position corresponding to the reinforcing structure 1421 are provided with a structure adapted to the raised structure for concave-convex cooperation, thereby increasing the contact area between the top cover assembly 10 and the box body 20, and further increasing the connection strength and stability between the top cover assembly 10 and the box body 20.

[0166] In addition, when the outer surface of the top cover body 14 has a raised structure or a recessed structure is formed on the outer surface due to the formation of a raised structure on the inner surface, when installing the top cover assembly 10, the assembler can hold the raised structure or hold the recessed structure with his hands, thereby improving the convenience of lifting the top cover assembly 10 during assembly and effectively improving the efficiency of assembly.

[0167] In some embodiments of the present application, as shown in FIG. 4 to FIG. 6 , FIG. 12 , FIG. 13 , and FIG. 15 , the reinforcement structure 1421 is provided on the side plate 142 of the top cover body 14 , and the reinforcement structure 1421 is provided as a recessed structure.

[0168] Specifically, a reinforcing structure 1421 having a recessed structure is formed on the side wall of the top cover body 14, wherein the reinforcing structure 1421 having a recessed structure is formed on the outer surface or the inner surface of the top cover body 14. When the recessed structure is formed on the outer surface of the top cover body 14, it may be a groove 145 structure formed on the outer surface of the top cover body 14, or it may be a recessed structure formed by recessing from the outer surface to the inner surface of the top cover body 14; when the raised structure is formed on the inner surface of the top cover body 14, it may be a groove 145 structure formed on the inner surface of the top cover body 14, or it may be a recessed structure formed by recessing from the inner surface to the outer surface of the top cover body 14.

[0169] In addition, the reinforcing structure 1421 of the recessed structure is arranged near the first connecting port 143 of the top cover body 14, wherein, when the recessed structure is formed in a recessed manner, the top of the box body 20 and the position corresponding to the reinforcing structure 1421 are provided with a structure adapted to the recessed structure for concave-convex cooperation, thereby increasing the contact area between the top cover assembly 10 and the box body 20, and further increasing the connection strength and stability between the top cover assembly 10 and the box body 20.

[0170] In addition, when the outer surface of the top cover body 14 has a groove 145 structure or a convex structure is formed on the outer surface due to the formation of a concave structure on the inner surface, when installing the top cover assembly 10, the assembler can hold the convex structure or hold the position of the concave structure with his hand, which improves the convenience of lifting the top cover assembly 10 during assembly and effectively improves the efficiency of assembly.

[0171] In some embodiments of the present application, the number of reinforcement structures 1421 provided on the top cover body 14 is one, and one reinforcement structure 1421 is provided along the circumference of the first connecting port 143, and one reinforcement structure 1421 can cover a part of the circumference of the first connecting port 143, or can cover the entire circumference of the first connecting port 143.

[0172] In some embodiments of the present application, as shown in FIG. 5 and FIG. 6 , a plurality of reinforcing structures 1421 are provided on the top cover body 14 , and all the reinforcing structures 1421 are arranged at intervals along the circumference of the top cover body 14 .

[0173] Specifically, in this embodiment, the number of the reinforcing structures 1421 is set to be multiple, and the reinforcing structures 1421 can be arranged according to the different structural shapes of the top cover body 14, and the overall structural strength of the top cover body 14 can be effectively enhanced through the reinforcing structures 1421.

[0174] It should be noted that the multiple reinforcement structures 1421 are spaced apart along the circumference of the top cover body 14, and the circumference of the top cover body 14 is consistent with the circumference of the first communication port 143. The multiple reinforcement structures 1421 can cover a portion of the circumference of the first communication port 143, or can cover the entire circumference of the first communication port 143.

[0175] In some embodiments of the present application, as shown in Figures 16 to 18, the heat dissipation duct 301 includes two parts, one part is the first duct 3011, and the other part is the second duct 3012. One end of the first duct 3011 is connected to the outside world, and the other end of the first duct 3011 is connected to the interior of the box 20. One end of the second duct 3012 is connected to the outside world, and the other end of the second duct 3012 is connected to the interior of the box 20.

[0176] The electric control box assembly 30 includes a box body and an electric control assembly. The box body has an installation space, which constitutes at least part of the first air duct 3011. The electric control assembly is installed inside the installation space, and the second air duct 3012 is arranged outside the installation space.

[0177] When blades 13 drive the airflow to exchange heat with the HVAC equipment outdoor unit 100, the outside airflow enters the interior of the housing 20 through the first air duct 3011 and the second air duct 3012, respectively. The airflow inside the housing 20 is then discharged through the top cover assembly 10. The outside airflow enters the first air duct 3011 and flows along the first air duct 3011, exchanging heat with the electronic control component. Simultaneously, the outside airflow passes through the second air duct 3012. As the airflow flows within the second air duct 3012, at least a portion of the electronic control component can exchange heat with the airflow within the second air duct 3012 through the sidewalls of the installation space. The provision of the first air duct 3011 and the second air duct 3012 effectively dissipates heat from the electronic control component, reducing the likelihood of the electronic control component malfunctioning due to high temperatures, thereby enabling the electronic control component to operate stably and efficiently.

[0178] It should be pointed out that during the operation of the electronic control component, the electronic devices it possesses will generate different amounts of heat due to their different functions. For example, capacitors and inductors generate relatively high amounts of heat, while integrated chips generate relatively low amounts of heat. The airflow in the first air duct 3011 is directly introduced into the position where the electronic control component is located, and the flowing airflow is directly in contact with the various devices of the electronic control component and performs heat exchange, thereby achieving heat dissipation of the electronic control component. The second air duct 3012 is arranged outside the installation space and corresponds to the position of the devices with relatively high heat generation in the electronic control component. The airflow in the second air duct 3012 exchanges heat with the devices with relatively high heat generation in the electronic control component through the side walls of the installation space, thereby achieving auxiliary heat dissipation of the electronic control component, so that the operating temperature of the electronic control component is maintained below the safe operating temperature, and the failure rate of the electronic control component is effectively reduced.

[0179] In addition, in the embodiment of the present application, the installation space of the box body constitutes the entire first air duct 3011, that is, one end of the receiving space is connected to the outside world, and the other end of the receiving space is connected to the interior of the box body 20, thereby forming the first air duct 3011.

[0180] In some embodiments of the present application, as shown in Figures 19 to 22, the box body includes a mounting plate 31, a first side plate 32, a second side plate 33, and a third side plate 36. The mounting plate 31 is connected and fixed to the box body 20, the first side plate 32 is connected and fixed to the bottom of the mounting plate 31, and the second side plate 33 and the third side plate 36 are connected and fixed to opposite sides of the mounting plate 31. The mounting plate 31, the second side plate 33, and part of the first side plate 32 together form an installation space, and the electronic control component is disposed in the installation space and is connected and fixed to the mounting plate 31. The mounting plate 31 and the third side plate 36 form a second air duct 3012.

[0181] The mounting plate 31, the first side plate 32, the second side plate 33 and the third side plate 36 are assembled to form a box structure. The overall structure is simple and can be processed separately and then assembled, thereby simplifying the processing difficulty and effectively reducing the manufacturing cost.

[0182] It should be understood that when the airflow passes through the second air duct 3012 , the airflow in the second air duct 3012 exchanges heat with the electronic control component through the mounting plate 31 to achieve heat dissipation of the electronic control component.

[0183] It should be pointed out that in the embodiment of the present application, when the box body is installed on the box body 20, the structure of the box body is adapted to the structure of the installation position of the box body 20, that is, the box body forms a structural complement to the installation position of the box body 20, so that after the electric control box assembly 30 is installed on the box body 20, the coordination of the overall external contour of the box body 20 can be improved.

[0184] In addition, the materials of the mounting plate 31, the first side plate 32, the second side plate 33, and the third side plate 36 can be all the same, partially the same, or all different. In the embodiment of the present application, the materials of the mounting plate 31, the first side plate 32, the second side plate 33, and the third side plate 36 are all the same, and can be metal parts (such as stainless steel parts) or non-metal parts (such as plastic parts).

[0185] In addition, the connection method between the first side panel 32 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection, or a snap connection. The connection method between the second side panel 33 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection, or a snap connection. The connection method between the third side panel 36 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection, or a snap connection.

[0186] In some embodiments of the present application, as shown in Figures 19 to 20, the electronic control component includes a communication control board 35 and a main control board 34. The main control board 34 and the communication control board 35 are respectively connected and fixed on the mounting plate 31, and the main control board 34 and the communication control board 35 are spaced apart.

[0187] Specifically, the communication control board 35 is used to communicate with the wired controller of the HVAC equipment in order to receive the control signal from the wired controller. In the prior art, the communication control board is external, that is, the communication control board 35 is installed on the outside of the box body 20. After long-term use, the fixing structure of the communication control board 35 will age. The aged fixing structure will break when subjected to external force (vibration or extrusion, etc.), causing the communication control board 35 to fall off and be damaged. In the embodiment of the present application, the communication control board 35 is built into the installation space of the box body, thereby reducing the problem of the fixing structure of the communication control board 35 being easily aged when the communication control board 35 is exposed, thereby reducing the possibility of the communication control board 35 falling off and being damaged.

[0188] In addition, the main control board 34 is electrically connected to the communication control board 35, which receives control signals from the wired controller and controls the HVAC equipment outdoor unit 100 based on the control signals. The main control board 34 and the communication control board 35 are spaced apart within the installation space to prevent the heat generated between them from being superimposed, thereby reducing the problem of excessive local temperature rise in the electronic control components. Furthermore, the main control board 34 and the communication control board 35 are spaced apart within the installation space to improve the fluidity of the airflow passing through the installation space (first air duct 3011), reducing the problem of airflow stagnation areas, and thus improving the heat dissipation effect on the electronic control components.

[0189] It should be noted that the communication control board 35 can be directly fixed on the mounting plate 31 of the box body, or can be fixed on the mounting plate 31 of the box body through a fixing bracket.

[0190] In addition, the main control board 34 is connected and fixed to the mounting plate 31 of the box body, and the main control board 34 and the mounting plate 31 are connected and fixed by connecting columns, so that there is a gap between the main control board 34 and the mounting plate 31, so that the air flow can pass between the main control board 34 and the mounting plate 31, thereby increasing the contact area between the air flow and the main control board 34, so that the heat exchange effect of the main control board 34 can be effectively improved.

[0191] In some embodiments of the present application, as shown in Figure 22, the electrical control box assembly 30 further includes a heat sink 38 arranged in the second air duct 3012, wherein the heat sink 38 is connected and fixed to the mounting plate 31, and the main control board 34 is correspondingly arranged to the heat sink 38, and the main control board 34 can be thermally connected to the heat sink 38 through the mounting plate 31.

[0192] Specifically, when the HVAC equipment outdoor unit 100 is running, the blades 13 rotate, causing the external air flow to enter the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 undergoes heat exchange with the main control board 34 and the communication control board 35 of the electronic control component. The air flow after the heat exchange enters the box body 20. The air flow entering the second air duct 3012 undergoes heat exchange with the main control board 34 through the heat sink 38 and the mounting plate 31 of the box body. The air flow after the heat exchange enters the box body 20. The air flow in the box body 20 is discharged to the outside through the top cover assembly 10 driven by the blades 13.

[0193] By providing the heat sink 38, the contact area between the second air duct 3012 and the air flow is increased, thereby further improving the heat dissipation efficiency and enabling the temperature of the electronic control component to be maintained within a safe operating range.

[0194] It should be pointed out that in the embodiment of the present application, the heat sink 38 is a fin structure. The heat sink 38 with a fin structure has a larger extension area, thereby increasing the contact area with the airflow, so that the heat dissipation efficiency can be further improved.

[0195] In addition, a heat-conducting medium (such as thermal grease, etc.) can be filled between the heat sink 38 and the mounting plate 31, thereby improving the heat conduction efficiency between the heat sink 38 and the mounting plate 31 and further improving the heat dissipation effect on the main control board 34.

[0196] In some embodiments of the present application, as shown in Figures 16 to 22, a first air inlet 3221 is provided on the first side panel 32 of the box body, and the mounting plate 31 and the third side panel 36 of the box body form a first air outlet. The first air inlet 3221 is located below the first air outlet, and the outside world is connected to one end of the second air duct 3012 through the first air inlet 3221, and the interior of the box body 20 is connected to the other end of the second air duct 3012 through the first air outlet. A second air inlet 3121 and a second air outlet 3111 are provided on the mounting plate 31 of the box body, wherein the second air inlet 3121 is located below the second air outlet 3111, and the outside world is connected to one end of the first air duct 3011 through the second air inlet 3121, and the interior of the box body 20 is connected to the other end of the first air duct 3011 through the second air outlet 3111.

[0197] By setting the first air inlet 3221 and the first air outlet, the structure of the second air duct 3012 with air inlet at the bottom and air outlet at the top is realized, thereby reducing the situation where foreign objects such as rainwater enter the interior of the box 20 through the second air duct 3012, and further reducing the situation where the HVAC equipment outdoor unit 100 malfunctions caused by foreign objects entering the interior of the box 20.

[0198] Similarly, by setting the second air inlet 3121 and the second air outlet 3111, the structure of air inlet at the bottom and air outlet at the top of the first air duct 3011 is also realized, thereby reducing the situation where foreign matter such as rainwater enters the interior of the box 20 through the first air duct 3011, and further reducing the situation where the HVAC equipment outdoor unit 100 malfunctions caused by foreign matter entering the interior of the box 20.

[0199] In some embodiments of the present application, as shown in Figures 17, 21, and 22, the box body further includes a hood member 37 having a third air outlet 372 defined thereon. The hood member 37 is fixedly connected to the mounting plate 31 of the box body. The third side panel 36 and the hood member 37 are located on the same side of the mounting plate 31. The mounting plate 31 and the hood member 37 form an air guide cavity, which is connected to the first air duct 3011 via the second air outlet 3111. The air guide cavity is connected to the interior of the box body 20 via the third air outlet 372. Vertically, the third air outlet 372 is located between the second air outlet 3111 and the first air outlet, wherein the second air outlet 3111 is spaced apart above the third air outlet 372, and the first air outlet is spaced apart below the third air outlet 372.

[0200] Specifically, when the HVAC equipment outdoor unit 100 is running, the blades 13 rotate, causing the external air flow to enter the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 performs heat exchange with the main control board 34 and the communication control board 35 of the electronic control component. The air flow after heat exchange passes through the second air outlet 3111, the air guide cavity and the third air outlet 372 in turn into the box body 20. The air flow entering the second air duct 3012 performs heat exchange with the main control board 34 through the heat dissipation component 38 and the mounting plate 31 of the box body. The air flow after heat exchange enters the box body 20 through the first air outlet. The air flow in the box body 20 is discharged to the outside through the top cover assembly 10 driven by the blades 13.

[0201] A hood member 37 is provided, and the third air outlet 372 on the hood member 37 is provided between the second air outlet 3111 and the first air outlet, wherein the second air outlet 3111 is spaced apart above the third air outlet 372, and the first air outlet is spaced apart below the third air outlet 372, so that the air outlet position of the first air duct 3011 can form a bending structure, thereby reducing the situation where foreign matter such as rainwater enters the installation space of the box body through the air outlet position of the first air duct 3011, reducing the adverse effects of foreign matter such as rainwater on the electronic control components, and effectively reducing the failure rate of the electronic control components.

[0202] It should be noted that the connection methods between the wind shield member 37 and the mounting plate 31 include but are not limited to riveting, welding, soldering, screw connection or snap connection.

[0203] In some embodiments of the present application, as shown in Figure 17, the second air inlet 3121 is arranged facing the third air outlet 372, a first air guide plate body 361 is provided on the third side panel 36 and is tilted away from the mounting plate 31, and a second air guide plate body 371 is provided on the wind cover member 37 and is tilted toward the mounting plate 31.

[0204] Specifically, along the vertical direction, the third air outlet 372 is located between the second air outlet 3111 and the first air outlet, wherein the second air outlet 3111 is spaced above the third air outlet 372, and the first air outlet is spaced below the third air outlet 372. At the same time, the second air inlet 3121 is arranged facing the third air outlet 372, so that the airflow after heat exchange discharged from the first air duct 3011 and the second air duct 3012 can be gathered together so that it can be quickly discharged to the outside under the drive of the blades 13, thereby reducing the escape of the airflow after heat exchange in the box body 20 and reducing the heating of other components in the box body 20 by the airflow after heat exchange.

[0205] In addition, the second air guide plate 371 is used to guide the airflow discharged through the third air outlet 372, so that the airflow through the third air outlet 372 flows toward the side of the mounting plate 31 close to the box body. When the airflow hits the mounting plate 31, the airflow discharged through the first air outlet can be fully mixed, so that it can be discharged to the interior of the box body 20 under the guidance of the first air guide plate 361.

[0206] It should be pointed out that the first air guide plate 361 is tilted away from the mounting plate 31. At this time, the first air guide plate 361 guides the airflow in an obliquely upward direction of the box body 20. At this time, the blade 13 is located at the top of the box body 20. By setting the first air guide plate 361, the airflow led out to the inside of the box body 20 through the first air guide plate 361 can flow to the position of the blade 13, reducing the escape of airflow in the box body 20, so that the heat exchange effect of the HVAC equipment outdoor unit 100 is effectively improved.

[0207] In some embodiments of the present application, as shown in Figures 16 to 22, the first side panel 32 includes a first horizontal panel 321 and a first vertical panel 322, the first horizontal panel 321 being vertically connected to the first vertical panel 322, and the mounting plate 31 includes a second horizontal panel 312 and a second vertical panel 311, the second horizontal panel 312 being vertically connected to the second vertical panel 311. The first side panel 32 is connected to the bottom of the mounting plate 31, and the first vertical panel 322 and the second vertical panel 311 are coplanarly arranged, and the first horizontal panel 321 and the second horizontal panel 312 are coplanarly spliced.

[0208] The second side panel 33 is an arc-shaped panel, one of whose arc-shaped edges is connected to the first horizontal panel and the second horizontal panel, and the other arc-shaped edge of the arc-shaped panel can be connected and sealed to the structure of the box body 20. In this case, the other two straight edges of the arc-shaped panel are respectively connected to the mounting plate 31 of the box body. In this case, the first horizontal plate 321, the second horizontal plate 312, the second vertical plate 311, and the first side panel 32 form an installation space for the first air duct 3011. The third side panel 36 is an L-shaped cover-like structure. The third side panel 36, part of the first vertical plate 322, part of the second vertical plate 311, and part of the second horizontal plate 312 form the second air duct 3012. Specifically, a first air inlet 3221 is provided on the first vertical plate 322 of the first side panel 32, and a second air inlet 3121 is provided on the second horizontal plate 312 of the mounting plate 31.

[0209] By configuring the mounting plate 31, first side plate 32, second side plate 33, third side plate 36, and mounting plate 31, the second air inlet 3121 of the first air duct 3011 is connected to the second air duct 3012. Driven by the blades 13, external airflow enters the second air duct 3012 through the first air inlet 3221. A portion of the airflow flows along the second air duct 3012 and is discharged through the first air outlet, while the remaining portion is discharged through the second air inlet 3121, the first air duct 3011, the second air outlet 3111, the air guide cavity, and the third air outlet 372. The structural design of the first and second air ducts 3011 and 3012 improves the smoothness of airflow while simplifying the structure, thereby achieving effective heat dissipation of the electronic control components.

[0210] It should be pointed out that in an embodiment of the present application, as shown in Figures 16 and 22, the second air duct 3012 is in an L-shaped structure, and the connecting position between the second air inlet 3121 and the second air duct 3012 is arranged close to the first air inlet 3221. When the air flow enters the second air duct 3012 through the first air inlet 3221, the air flow flows through two paths, one part continues to flow along the path of the second air duct 3012, and the other part enters the air duct through the second air inlet 3121 and flows along the path of the first air duct 3011.

[0211] In addition, the amount of air entering the first air duct 3011 can be controlled by setting the connection position between the second air inlet 3121 and the second air duct 3012 to meet the heat dissipation requirements of different electronic control components.

[0212] In some embodiments of the present application, as shown in Figures 18 and 20, the first air inlet 3221 includes a first louver hole, and the number of the first louver holes is multiple. A first guide portion is provided at a part of the hole openings of the first louver hole, wherein the first guide portion is connected to the hole opening on one side of the first horizontal plate body 321 of the first louver hole close to the first side plate 32, and the first vertical plate body 322 is provided at an acute angle to the first guide portion.

[0213] Specifically, along the vertical direction, one end of the first air guide is connected to the opening on the upper side of the first louver (the opening on the side close to the first horizontal plate 321), and the other end of the first air guide is arranged at an acute angle to the first vertical plate 322. The first air guide can be located inside or outside the second air duct 3012. The drawings of this application show that the first air guide is located outside the second air duct 3012. Specifically, in this case, the air inlet direction of the first air inlet area formed between the first air guide and the first louver is obliquely upward, that is, the external airflow enters the second air duct 3012 from the obliquely downward direction of the first louver under the guidance of the first air guide structure through the first louver. The configuration of the first louver enables air inlet from the obliquely downward direction of the first air inlet 3221, thereby reducing the ingress of foreign matter such as rainwater through the first air inlet 3221, thereby reducing the adverse effects of foreign matter such as rainwater on the HVAC equipment outdoor unit 100.

[0214] It should be noted that, along the vertical direction, the cross section of the first louver hole is a fan-shaped structure.

[0215] In addition, multiple first louver holes are arranged at intervals. When the first side plate 32 is a metal part (such as a stainless steel part), the first louver holes can be processed by stamping. When the first side plate 32 is a non-metallic part (such as a plastic part), it can be processed by injection molding.

[0216] In addition, the angle between the first vertical plate 322 and the first air guide portion may be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°.

[0217] In some embodiments of the present application, as shown in Figure 18, the second air inlet 3121 includes a second louver hole, and the number of the second louver holes is multiple. A second air guide portion is provided at some of the hole openings of the second louver hole, wherein the second air guide portion is connected to the hole opening on one side of the first vertical plate body 322 of the second louver hole close to the mounting plate 31, and the second horizontal plate body 312 of the mounting plate 31 is set at an acute angle to the second air guide portion.

[0218] In the horizontal direction, one end of the second air guide portion is connected to the opening of the second louver hole near the second vertical plate body 311, and the other end of the air guide portion is set at an acute angle to the second horizontal plate body 312. The second air guide portion can be located on the inner side of the first air duct 3011, or on the inner side of the second air duct 3012 (i.e., the outer side of the first air duct 3011). The drawings of the present application show that the second air guide portion is located on the inner side of the first air duct 3011. Specifically, when the airflow in the second air duct 3012 enters the first air duct 3011 through the second louver hole, under the guidance of the second air guide portion, the airflow flows in the direction away from the second vertical plate body 311 of the mounting plate 31. By setting the second air guide portion, the airflow in the second air duct 3012 can be effectively guided into the first air duct 3011, so that the airflow can be effectively distributed in the first air duct 3011 and the second air duct 3012, thereby effectively improving the heat dissipation effect of the electronic control components.

[0219] In addition, the second air inlet 3121 of the first air duct 3011 is connected to the second air duct 3012, thereby reducing the possibility of foreign matter such as rainwater entering the interior of the box body, and reducing the possibility of malfunction of the electric control box assembly 30 caused by foreign matter such as rainwater entering the interior of the box body, thereby effectively improving the stable operation of the HVAC equipment outdoor unit 100.

[0220] It should be noted that, along the vertical direction, the cross section of the second louver holes is a fan-shaped structure.

[0221] In addition, multiple second louver holes are arranged at intervals. When the mounting plate 31 is a metal part (such as a stainless steel part), the second louver holes can be processed by stamping. When the second side plate 33 is a non-metallic part (such as a plastic part), it can be processed by injection molding.

[0222] In addition, the angle between the second horizontal plate 312 and the second air guide portion may be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°.

[0223] In some embodiments of the present application, as shown in Figures 17 and 20, the second air outlet 3111 includes a third louver hole, the number of the third louver holes is multiple, and a third guide portion is provided at some hole positions of the third louver holes, wherein the third guide portion is used to guide the airflow discharged from the first air duct 3011 toward the direction of the second air inlet 3121.

[0224] Specifically, vertically, one end of the third air guide is connected to the opening below the third louver (near the opening of the first side panel 32), and the other end of the third air guide is arranged at an acute angle to the second vertical plate 311 of the mounting plate 31. The third air guide can be located inside the first air duct 3011 or outside the second air duct 3012. The drawings of this application illustrate that the second air guide is located inside the first air duct 3011. Specifically, the airflow direction of the third air inlet area formed between the third air guide and the third louver is obliquely downward. That is, the airflow within the first air duct 3011 is guided by the third air guide and then discharged from the first air duct 3011 in an obliquely downward direction through the third louver. The provision of the third louver structure enables obliquely downward airflow from the second air outlet 3111, thereby reducing the ingress of rainwater and other foreign matter through the second air outlet 3111, thereby reducing the adverse effects of rainwater and other foreign matter on the HVAC equipment outdoor unit 100.

[0225] It should be pointed out that, along the vertical direction, the cross section of the third louver hole is a fan-shaped structure.

[0226] In addition, multiple third louver holes are arranged at intervals. When the mounting plate 31 is a metal part (such as a stainless steel part), the third louver holes can be processed by stamping. When the mounting plate 31 is a non-metallic part (such as a plastic part), it can be processed by injection molding.

[0227] In addition, the angle between the second vertical plate body 311 of the mounting plate 31 and the third air guide portion may be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°.

[0228] In some embodiments of the present application, the second air inlet 3121 is configured as a second louver hole, wherein the second louver hole has an opening area S1, 0<S1≤12mm 2 .

[0229] Specifically, when S1>12mm 2 When the opening area of ​​the second air inlet 3121 is too large, the mosquito barrier effect is poor. In the embodiment of the present application, by setting S1 to 0<S1≤12mm 2 , so that the second air inlet 3121 can block mosquitoes and the like, reducing the situation where mosquitoes enter the interior of the box through the second air inlet 3121, thereby reducing the situation where mosquitoes enter the interior of the box and damage the electronic control components, further reducing the failure rate of the electronic control box components.

[0230] It should be noted that the shape of the opening of the second louver hole can be a circular hole, a square hole, an elliptical hole, etc.

[0231] In addition, the opening area S1 of the second louver hole can be set to 2mm2 , 4mm 2 , 6mm 2 , 8mm 2 , 10mm 2 , 12mm 2 .

[0232] In some embodiments of the present application, the third air outlet 372 includes a plurality of holes, wherein the opening area of ​​each hole is S2, 0<S2≤28.26mm 2 .

[0233] Specifically, when S1>28.26mm 2 When the opening area of ​​the third air outlet 372 is too large, the mosquito barrier effect is poor. In the embodiment of the present application, by setting S2 to 0<S2≤28.26mm 2 , so that the third air outlet 372 can block mosquitoes and the like, reducing the situation where mosquitoes enter the interior of the box body through the third air outlet 372, thereby reducing the situation where mosquitoes enter the interior of the box body and damage the electronic control components, further reducing the failure rate of the electronic control box body components.

[0234] It should be noted that the shape of the hole forming the third air outlet 372 may be a circular hole, a square hole, an elliptical hole, or the like.
