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.

[0057] As shown in FIG. 1 to FIG. 15 , 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 and a top cover assembly 10 .

[0058] 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 is connected to the heat exchanger 40 through the air guide channel 155.

[0059] 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.

[0060] 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.

[0061] In the prior art, the heat exchanger 40 is arranged in an annular manner radially outside the blades 13, and the diameter of the blades 13 is limited by the structural shape of the heat exchanger 40. As shown in FIG2 , in an embodiment of the present application, the top cover body 14 is located above the heat exchanger 40, and the blades 13 are arranged in the air guide channel 155 of the air guide cover 15. At this time, the blades 13 are located outside the heat exchanger 40, which removes the restriction of the heat exchanger 40 on the blades 13, allowing the diameter of the blades 13 to be effectively increased. The enlarged blades 13 can have a stronger driving force for the airflow, thereby reducing the airflow stagnation inside the HVAC equipment outdoor unit 100 and enhancing the heat exchange capacity of the HVAC equipment outdoor unit 100.

[0062] 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 can be from the heat exchanger 40 to the blades 13, that is, the airflow at the position of 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 position of the heat exchanger 40, thereby achieving heat exchange between the flowing airflow and the heat exchanger 40.

[0063] 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.

[0064] 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.

[0065] 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 .

[0066] 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.

[0067] 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.

[0068] 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.

[0069] It should be noted that the top of the box body 20 and the first communication port 143 are plugged into each other, which means 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. In the embodiment of the present application, the top of the box body 20 is plugged into the first communication port 143.

[0070] In some embodiments of the present application, as shown in Figure 6, a second connecting port 144 is provided on the top surface of the top cover body 14. At this time, the second connecting port 144 and the first connecting port 143 are located on opposite sides of the top cover body 14.

One end of the air guide channel 155 of the air guide cover 15 is connected to the first connecting port 143, and the other end is connected to the outside world through the second connecting port 144.

[0071] Among them, the top cover assembly 10 is arranged on the top of the box body 20 of the HVAC equipment outdoor unit 100, the first connecting port 143 of the top cover body 14 is plugged into the top of the outdoor unit, and the interior of the box body 20 is connected to the receiving space of the top cover body 14 through the first connecting hole, and is connected to the outside world through the second connecting port 144.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] In addition, the shape of the opening of the first connecting port 143 includes but is not limited to circle, square, pentagon, hexagon, triangle, ellipse, diamond, etc.; similarly, the shape of the opening of the second connecting port 144 includes but is not limited to circle, square, pentagon, hexagon, triangle, ellipse, diamond, etc.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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 .

[0083] It should be understood that, in the direction from the first communication opening 143 to the second communication 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.

[0084] 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 .

[0085] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 ).

[0099] 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 ).

[0100] 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.

[0101] 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 .

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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 .

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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 a separate structure, they can be processed separately and then connected and fixed by bonding, screw connection, welding, riveting, or clamping.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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 .

[0120] 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.

[0121] 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 .

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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 .

[0138] 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.

[0139] 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.

The blades 13 are arranged in the air guide channel 155 of the air guide cover 15. At this time, 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 area in the HVAC equipment outdoor unit 100, so that the heat exchange effect of the HVAC equipment outdoor unit 100 is effectively improved.
