[0095] like Figures 1 to 23 As shown, according to an embodiment of the present invention, a HVAC equipment outdoor unit 100 is proposed. The HVAC equipment outdoor unit 100 includes a box body 20, a heat exchanger 40, a top cover assembly 10 and an electric control box assembly 30.

[0096] 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 inside 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.

[0097] In the prior art, the heat exchanger 40 is disposed in a ring on the radially outer side of the blade 13. In this case, the diameter of the blade 13 is limited by the structural shape of the heat exchanger 40. In this case, the driving ability of the blade 13 on the airflow is limited.

[0098] In an embodiment of the present invention, Figure 2 and Fig.16 As shown, the blade 13 is arranged above the heat exchanger 40, that is, the blade 13 is arranged on the outside of the heat exchanger 40, so that the size of the blade 13 is not limited by the structural size of the heat exchanger 40. By increasing the size of the blade 13, the driving ability of the blade 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. At the same time, the interior of the box body 20 can be connected to the outside through the heat dissipation duct 301 of the electric control box assembly 30. Driven by the blade 13, the airflow can enter the heat dissipation duct 301 to achieve heat dissipation of the electric control box assembly 30, further reducing the problem of airflow stagnation area in the HVAC equipment outdoor unit 100.

[0099] It should be noted that in the embodiment of the present invention, the electric control box assembly 30 is used to control the HVAC equipment outdoor unit 100 accordingly, wherein the control methods include but are not limited to power on, power off, and working mode switching, etc. The electric control box assembly generates heat during operation. If the electric control box assembly 30 is not effectively cooled, the electric control box assembly 30 will malfunction due to excessive temperature, thereby affecting the operation of the HVAC equipment outdoor unit 100.

[0100] In some embodiments of the present invention, the top cover assembly 10 includes an air duct 15 and a top cover body 14 having a receiving space. The top of the box body 20 is connected to the top cover body 14, the air duct 15 is arranged in the receiving space and is connected and fixed to the top cover body 14, and the blades 13 are arranged in the air guide channel 155 of the air duct 15.

[0101] Specifically, the top cover assembly 10 includes an air duct 15, blades 13, and a top cover body 14 having a receiving space, the top cover body 14 is arranged outside the box body 20 and is connected and fixed to the top of the box body 20, the air duct 15 is arranged in the receiving space of the top cover body 14, and the blades 13 are arranged in the air guide channel 155 of the air duct 15 and can rotate relative to the air guide channel 155. The outside world can communicate with the heat exchanger 40 through the air guide channel 155.

[0102] like Figure 1 and Figure 3As shown, 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 blade 13 is set in the air guide channel 155 of the air guide cover 15. At this time, the blade 13 is set on the outside of the heat exchanger 40, so that the size of the blade 13 is not limited by the structural size of the heat exchanger 40. By increasing the size of the blade 13, the driving ability of the blade 13 to 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.

[0103] 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.

[0104] It should be noted that when the blades 13 rotate, driven by the blades 13, the flow direction of the airflow can be from the heat exchanger 40 to the blades 13, and the flow direction of the airflow can also be from the blades 13 to the heat exchanger 40. In the embodiment of the present invention, the flow direction of the airflow is 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 after 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, so as to achieve heat exchange between the flowing airflow and the heat exchanger 40.

[0105] In addition, the blade 13 may be a metal part or a non-metal part. In the embodiment of the present invention, the blade 13 is a non-metal part, such as plastic or carbon fiber, and can be processed and manufactured by an integral molding method, thereby improving the processing efficiency.

[0106] It should be pointed out that if Figure 3 As shown, 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 narrow 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.

[0107] In addition, if Figure 3 As shown, an air guide cover 15 is provided to wrap the blades 13, thereby reducing the noise transmitted to the outside during the rotation of the blades 13, so that the noise during the operation of the HVAC equipment outdoor unit 100 is effectively reduced.

[0108] In the present invention, 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 a 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.

The top of the box body 20 of the HVAC equipment outdoor unit 100 is plugged into the first communication port 143.

[0110] Specifically, the first communication 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. The plug-in matching method has a simple structure and can effectively optimize the structure, so that the manufacturing cost is effectively reduced. In addition, the plug-in matching method is easy to assemble, which can effectively improve the production efficiency and effectively reduce the production cost.

[0111] 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. In the embodiment of the present invention, the top of the box body 20 is plugged into the first communication port 143.

[0112] In some embodiments of the present invention, Figure 6 As shown, a second connecting port 144 is opened 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 through the second connecting port 144.

[0113] 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, the interior of the box body 20 is connected to the accommodating space of the top cover body 14 through the first connecting hole, and is connected to the outside through the second connecting port 144.

[0114] 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 airflow 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.

[0115] 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.

[0116] 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 through the first connecting port 143, the interior of the top cover body 14 and the second connecting port 144.

[0117] In addition, the shape of the hole 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 hole of the second connecting port 144 includes but is not limited to circle, square, pentagon, hexagon, triangle, ellipse, diamond, etc.

[0118] In addition, the flow cross-sectional area of ​​the first communication port 143 and the flow cross-sectional area of ​​the second communication port 144 may be equal to or different from each other.

[0119] In some embodiments of the present invention, the top cover assembly 10 further includes a mesh cover 11 installed 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 arranging the mesh cover 11 at the second communication port 144, the second communication port 144 is shielded on the basis of enabling airflow exchange between the second communication port 144 and the outside world, thereby reducing the situation where foreign matter outside falls into the inside of the top cover body 14 and the inside of the box body 20 through the second communication port 144.

[0120] It should be pointed out 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.

[0121] 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.

[0122] 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 and the like.

[0123] In some embodiments of the present invention, Figure 6 and Fig.10 As shown, 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 abuts against the bottom surface of the groove 145.

[0124] Specifically, the shape of the groove 145 matches the shape of the mesh cover 11 , and the groove 145 is provided, and the mesh cover 11 is limited by the groove 145 , so that the mesh cover 11 is positioned and installed, thereby improving the installation accuracy of the mesh cover 11 .

[0125] 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.

[0126] In addition, a groove 145 is provided on the top surface of the top cover body 14 , and the strength of the top cover body 14 is further enhanced by utilizing the structural changes, thereby further improving the overall structural strength of the top cover body 14 .

[0127] It should be noted that a reinforcing rib 1422 is provided on the bottom surface of the groove 145, and 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 concave structure.

[0128] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the top cover assembly 10 also includes a driving member 12. The mesh cover 11 of the top cover assembly 10 has a side facing the second communication port 144, the driving member 12 is fixedly mounted on the side, and the blade 13 is connected to the driving shaft of the driving member 12 and is rotatably arranged in the air guide channel 155 of the air guide cover 15.

[0129] Specifically, when the HVAC equipment outdoor unit 100 is in operation, the driving member 12 rotates and drives the blades 13 to rotate. During the rotation of the blades 13, the airflow flows from the first connecting port 143 to the second connecting port 144, or the airflow flows from the second connecting port 144 to the first connecting port 143. The airflow is driven by the blades 13 and the driving member 12, thereby improving the heat exchange efficiency of the HVAC equipment outdoor unit 100.

[0130] 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, so that the installation position of the blade 13 can be limited, reducing the noise generated by the blade 13 during operation due to vibration and other reasons.

[0131] It should be understood that, in the invention, 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 invention, driven by the blades 13 and the driving member 12, the airflow flows from one side of the first connecting port 143 to one side of the second connecting port 144.

[0132] It should be noted that in the invention, the connection between the driving member 12 and the mesh cover 11 includes but is not limited to screw connection, snap connection, bonding, welding, riveting, etc. Meanwhile, the blade 13, the first communication port 143, and the second communication port 144 are coaxially arranged.

[0133] In addition, the driving member 12 includes but is not limited to an electric motor or a starter motor.

[0134] In some embodiments of the present invention, the top cover body 14 is an integrated structure, and the top cover body 14 of the integrated structure is integrally formed and manufactured.

[0135] In some embodiments of the present invention, Fig.14 and Fig.15 As shown, the top cover body 14 is a split structure, including a side panel 142 and a corner panel 141, wherein the number of the side panel 142 is at least one, the number of the 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, 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.

[0136] By splitting the top cover body 14 into two parts, namely the side plate 142 and the angle plate 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.

[0137] 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 of the cylindrical structure, the bent position of the corner plate 141 constitutes a part of the groove 145 for accommodating the mesh cover 11 .

[0138] When the number of the side plate 142 is one, the side plate 142 is bent and the two free ends after the bending are connected and fixed by bonding or welding, so as to form a cylindrical structure.

[0139] When there are multiple side panels 142 (two or more), a cylindrical structure is formed by assembling all side panels 142 (the connection methods at the assembly positions include but are not limited to screw connection, bonding, riveting, snap connection or welding, etc.). Providing multiple side panels 142 can further split the structure, so that the difficulty of the manufacturing process is further reduced.

[0140] Furthermore, 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 ).

[0141] 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 away from the first communication port 143 ).

[0142] In some embodiments of the present invention, the side panels 142 of the top cover body 14 form a cylindrical structure, the cylindrical structure has two openings arranged opposite to each other, one of the openings 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.

[0143] By providing the flange 1423 , the contact area between the side plate 142 and the angle plate 141 is increased, so that the connection strength between the angle plate 141 and the side plate 142 is enhanced, and the overall structural strength of the top cover body 14 is further improved.

[0144] In some embodiments of the present invention, Figures 7 to 9As shown, 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 shielded by the shielding portion 152.

[0145] 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 shielding parts 152 in the present invention is also four. The four shielding parts 152 are arranged at intervals along the circumferential direction of 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 of airflow entering 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 of airflow stagnation area in the HVAC equipment outdoor unit 100, and improving the heat exchange effect of the HVAC equipment outdoor unit 100.

[0146] It should be understood that the shielding portion 152 and the main body 151 can be an integrated structure or a split structure. When the shielding portion 152 and the main body 151 are an integrated structure, they can be processed and manufactured by an integrated molding method. When the shielding portion 152 and the main body 151 are split structures, they are first processed separately and then connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0147] It should be noted that along the axial direction of the main body 151 of the cylindrical structure, all shielding parts 152 can be located on the same circumferential surface or can be arranged at intervals. In the embodiment of the present invention, all shielding parts 152 are located on the same circumferential surface, so that the structural stability of the air guide cover 15 reaches the best effect, and the shaking of the air guide cover 15 caused by the rotation of the blades 13 is reduced.

[0148] 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 is 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.

[0149] 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 invention, the air guide cover 15 is a cylindrical structure, and the two ends of the cylindrical structure are respectively 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 outlet.

[0150] 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 for the airflow.

[0151] In some embodiments of the invention, Fig. 9 As shown, a wire hole 156 for passing the connecting wire of the driving member 12 is provided on the air guide cover 15. By providing the wire hole 156, it is convenient to lead out the connecting wire of the driving member 12, improve the convenience of assembly, and thus effectively improve the efficiency of assembly.

[0152] It should be noted that the wire-passing hole 156 includes but is not limited to a round hole, a square hole, a diamond hole, a triangular hole, an elliptical hole, a pentagonal hole or a hexagonal hole, etc.

[0153] 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 scoop passage 155 of the air scoop 15 and to reduce the influence of the connecting wire on the air scoop passage 155 .

[0154] In some embodiments of the present invention, Figures 7 to 9 As shown, 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.

[0155] 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 the difference in 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.

[0156] In addition, by setting the connection mode between the connection portion 153 and the top cover body 14, the connection mode between the two can be set according to specific needs, thereby improving the flexibility of assembly. As a specific implementation, in the present invention, the air guide cover 15 is bonded and fixed to the top cover body 14, and the bonding method is convenient for assembly and the connection position has good structural strength, which can effectively meet the needs of use.

[0157] It should be understood that the connection portion 153 and the main body 151 can be an integrated structure or a split structure. When the connection portion 153 and the main body 151 are an integrated structure, they can be processed and manufactured by an integrated molding method. When the connection portion 153 and the main body 151 are split structures, they are first processed separately and then connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0158] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the air guide cover 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 connecting position between the main body 151 and the connecting portion 153, and the connecting position between the main body 151 and the shielding portion 152.

[0159] 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.

[0160] It should be pointed out that in the embodiment of the present invention, a reinforcing portion 154 is provided on each of the shielding portion 152, the connecting portion 153, the main body 151, the connecting position between the main body 151 and the connecting portion 153, and the connecting 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.

[0161] In addition, the reinforcement parts 154 are dispersedly arranged on the air guide cover 15 , so that the structure of the air guide cover 15 can be further uniform, and the overall structural strength of the air guide cover 15 can be further improved.

[0162] In some embodiments of the present invention, the reinforcing portion 154 includes at least one of a groove 145 , a convex bulge, and a rib.

[0163] By setting the structure of the reinforcement part 154, the reinforcement part 154 can effectively meet the use requirements. Among them, one structure of the groove 145, the convex bump and the rib plate can be used as the reinforcement part 154, two structures can be used as the reinforcement part 154, and three structures can be used as the reinforcement part 154.

[0164] In an embodiment of the present invention, the groove 145 and the rib plate are both set as the reinforcement structure 1421, that is, a part of the reinforcement structure 1421 is the groove 145, and the other part of the reinforcement structure 1421 is the rib plate. Through the combination of the two, the overall structure of the air guide cover 15 can be effectively enhanced.

[0165] In some embodiments of the present invention, Figures 4 to 6 , Fig.12 , Fig.13 , Fig.15 As shown, the top cover body 14 is further provided with a reinforcement structure 1421 located between the first communication port 143 and the top surface.

[0166] Specifically, the reinforcing structure 1421 is arranged between the top surface and the first connecting port 143. The distance between the reinforcing structure 1421 and the top surface is greater than the distance between the reinforcing 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 reinforcing 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 the insufficient structural strength of the top cover assembly 10.

[0167] 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.

[0168] 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 invention, the reinforcing structure 1421 is integrally formed with the top cover body 14, thereby reducing the processing steps and effectively improving the production efficiency.

[0169] It should be noted that by providing the reinforcement structure 1421 on the top cover body 14, the air guide cover 15 does not need to be weighed, and the material of the air guide cover 15 can be optimized, which can not only reduce the mass of the air guide cover 15, but also effectively reduce the manufacturing cost of the air guide cover 15. For example, in the present invention, the air guide cover 15 can be provided with a component formed of wind plastic or foam material.

[0170] In some embodiments of the present invention, the reinforcement structure 1421 is disposed on the side plate 142 of the top cover body 14, and the reinforcement structure 1421 is configured as a protruding structure.

[0171] Specifically, a reinforcing structure 1421 which is a raised structure is formed on the side plate 142 of the top cover body 14, wherein the reinforcing 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 of the top cover body 14 to the inner surface.

[0172] In addition, a reinforcing structure 1421 of a 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, a structure matching the raised structure is arranged at a position corresponding to the reinforcing structure 1421 at the top of the box body 20 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.

[0173] 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, which improves the convenience of lifting the top cover assembly 10 during assembly and effectively improves the efficiency of assembly.

[0174] In some embodiments of the present invention, Figures 4 to 6 , Fig.12 , Fig.13 , Fig.15 As shown, the reinforcement structure 1421 is disposed on the side plate 142 of the top cover body 14, and the reinforcement structure 1421 is configured as a recessed structure.

[0175] Specifically, the reinforcing structure 1421, which is a recessed structure, is formed on the side wall of the top cover body 14, wherein the reinforcing structure 1421, which is 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 can be a groove 145 structure formed on the outer surface of the top cover body 14, or it can be a recessed structure formed by being recessed 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 can be a groove 145 structure formed on the inner surface of the top cover body 14, or it can be a recessed structure formed by being recessed from the inner surface to the outer surface of the top cover body 14.

[0176] 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 arranged with a structure that matches 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.

[0177] 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 a recessed structure formed on the inner surface, when installing the top cover assembly 10, the assembler can hold the convex structure or hold the position of the recessed structure with his hand, which improves the convenience of lifting the top cover assembly 10 during assembly and effectively improves the efficiency of assembly.

[0178] In some embodiments of the present invention, 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.

[0179] In some embodiments of the present invention, Figure 5 and 6 As shown, 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 .

[0180] 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 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.

[0181] It should be noted that the plurality of reinforcing structures 1421 are arranged at intervals 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 plurality of reinforcing structures 1421 may cover a part of the circumference of the first communication port 143, or may cover the entire circumference of the first communication port 143.

[0182] In some embodiments of the present invention, Figures 16 to 18 As shown, the heat dissipation air duct 301 includes two parts, one part is the first air duct 3011, and the other part is the second air duct 3012. One end of the first air duct 3011 is connected to the outside, and the other end of the first air duct 3011 is connected to the interior of the box 20. One end of the second air duct 3012 is connected to the outside, and the other end of the second air duct 3012 is connected to the interior of the box 20.

[0183] 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.

[0184] When the blades 13 drive the airflow to exchange heat with the outdoor unit 100 of the HVAC equipment, the external airflow enters the interior of the box 20 through the first air duct 3011 and the second air duct 3012 respectively, and the airflow inside the box 20 is discharged through the top cover assembly 10. The external airflow enters the first air duct 3011 and flows along the first air duct 3011, and the flowing airflow exchanges heat with the electric control component. At the same time, the external airflow passes through the second air duct 3012. When the airflow flows in the second air duct 3012, at least part of the electric control component can exchange heat with the airflow in the second air duct 3012 through the side wall of the installation space. The first air duct 3011 and the second air duct 3012 are provided, so that the electric control component can be effectively dissipated, and the situation where the electric control component fails due to high temperature is reduced, so that the electric control component can operate stably and efficiently.

[0185] It should be pointed out that during the operation of the electric control component, the electronic devices it possesses will generate different amounts of heat due to their different functions. For example, capacitors and inductors have relatively high heat generation, while integrated chips have relatively low heat generation. The airflow in the first air duct 3011 is directly introduced to the position of the electric control component, and the flowing airflow is used to directly contact and exchange heat with the various devices of the electric control component, thereby achieving heat dissipation of the electric 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 electric control component. The airflow in the second air duct 3012 exchanges heat with the devices with relatively high heat generation in the electric control component through the side walls of the installation space, thereby achieving auxiliary heat dissipation of the electric control component, so that the operating temperature of the electric control component is maintained below the safe operating temperature, and the failure rate of the electric control component is effectively reduced.

[0186] In addition, in the embodiment of the present invention, 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, 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.

[0187] In some embodiments of the present invention, Figures 19 to 22 As shown, 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 the opposite sides of the mounting plate 31. The mounting plate 31, the second side plate 33 and a part of the first side plate 32 together enclose an installation space, the electric control component is arranged in the installation space and is connected and fixed to the mounting plate 31, and the mounting plate 31 and the third side plate 36 enclose a second air duct 3012.

[0188] 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 difficulty of processing and effectively reducing the manufacturing cost.

[0189] 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.

[0190] It should be pointed out that in the embodiment of the present invention, 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.

[0191] 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 may be all the same, partly the same, or all different. In the embodiment of the present invention, 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 may be metal parts (such as stainless steel parts, etc.) or non-metal parts (such as plastic parts, etc.).

[0192] In addition, the connection method between the first side plate 32 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection or snap connection. The connection method between the second side plate 33 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection or snap connection. The connection method between the third side plate 36 and the mounting plate 31 includes, but is not limited to, riveting, welding, welding, screw connection or snap connection.

[0193] In some embodiments of the present invention, Figure 19 to Figure 20 As shown, the electric control assembly 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 from each other.

[0194] Specifically, the communication control board 35 is used to communicate with the wire controller of the HVAC equipment so as to receive the control signal of the wire 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 fixed structure of the communication control board 35 will age. The aged fixed structure will break when subjected to external force (vibration or extrusion, etc.), thereby causing the communication control board 35 to fall off and be damaged. In the embodiment of the present invention, the communication control board 35 is built into the installation space of the box body, thereby reducing the problem of the fixed structure of the communication control board 35 being easily aged when the communication control board 35 is exposed, thereby reducing the situation of the communication control board 35 falling off and being damaged.

[0195] In addition, the main control board 34 is electrically connected to the communication control board 35, receives the control signal of the wire controller through the communication control board 35, and controls the outdoor unit 100 of the HVAC equipment according to the control signal. The main control board 34 and the communication control board 35 are arranged at intervals in the installation space, so that the heat generated between the two will not be superimposed, thereby reducing the problem of excessive local temperature rise of the electric control components. At the same time, the main control board 34 and the communication control board 35 are arranged at intervals in the installation space, so that the fluidity of the airflow passing through the installation space (first air duct 3011) can be better, reducing the problem of airflow stagnation area, thereby improving the heat dissipation effect of the electric control components.

[0196] It should be noted that the communication control board 35 can be directly fixed on the mounting plate 31 of the box body, and can also be fixed on the mounting plate 31 of the box body through a fixing bracket.

[0197] In addition, the main control board 34 is connected and fixed on 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 airflow can pass between the main control board 34 and the mounting plate 31, thereby increasing the contact area between the airflow and the main control board 34, so that the heat exchange effect of the main control board 34 can be effectively improved.

[0198] In some embodiments of the present invention, Fig. 22 As shown, the electric control box assembly 30 also includes a heat sink 38 disposed 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 disposed 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.

[0199] Specifically, when the HVAC equipment outdoor unit 100 is running, the blades 13 rotate, so that the external air flow enters the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 exchanges heat 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 exchanges heat 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 driven by the blades 13 and discharged to the outside through the top cover assembly 10.

[0200] 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, so that the temperature of the electronic control component can be maintained within a safe operating range.

[0201] It should be pointed out that in the embodiment of the present invention, the heat sink 38 is a fin structure, and the heat sink 38 with a fin structure has a larger extension area, so that the contact area with the airflow can be increased, so that the heat dissipation efficiency can be further improved.

[0202] In addition, a heat-conducting medium (such as thermal grease, etc.) can be filled between the heat sink 38 and the mounting plate 31 to improve the heat conduction efficiency between the heat sink 38 and the mounting plate 31 and further enhance the heat dissipation effect on the main control board 34 .

[0203] In some embodiments of the present invention, Figures 16 to 22As shown, a first air inlet 3221 is provided on the first side plate 32 of the box body, and the mounting plate 31 of the box body and the third side plate 36 form a first air outlet. The first air inlet 3221 is located below the first air outlet, and the outside is connected to one end of the second air duct 3012 through the first air inlet 3221, and the inside 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 is connected to one end of the first air duct 3011 through the second air inlet 3121, and the inside of the box body 20 is connected to the other end of the first air duct 3011 through the second air outlet 3111.

[0204] By setting the first air inlet 3221 and the first air outlet, a structure in which the second air duct 3012 has air inlet at the bottom and air outlet at the top is realized, thereby reducing the possibility of foreign matter such as rainwater entering the interior of the box 20 through the second air duct 3012, thereby reducing the possibility of malfunction of the HVAC equipment outdoor unit 100 caused by foreign matter entering the interior of the box 20.

[0205] Similarly, by setting the second air inlet 3121 and the second air outlet 3111, the structure of the first air duct 3011 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 first air duct 3011, and further reducing the situation where the HVAC equipment outdoor unit 100 malfunctions caused by foreign objects entering the interior of the box 20.

[0206] In some embodiments of the present invention, Fig.17 , Fig.21 as well as Fig. 22 As shown, the box body also includes a hood member 37, on which a third air outlet 372 is provided, the hood member 37 is connected and fixed to the mounting plate 31 of the box body, the third side plate 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, the air guide cavity is connected to the first air duct 3011 through the second air outlet 3111, and the air guide cavity is connected to the interior of the box body 20 through the third air outlet 372. In 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.

[0207] Specifically, when the HVAC equipment outdoor unit 100 is running, the blades 13 rotate, so that the external air flow enters the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 exchanges heat 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 through the second air outlet 3111, the air guide cavity and the third air outlet 372 in turn. The air flow entering the second air duct 3012 exchanges heat 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 through the first air outlet. Driven by the blades 13, the air flow in the box body 20 is discharged to the outside through the top cover assembly 10.

[0208] A wind cover member 37 is provided, and the third air outlet 372 on the wind cover member 37 is provided 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, so that the air outlet position of the first air duct 3011 can form a bending structure, thereby reducing the situation in which 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 electric control components, and effectively reducing the failure rate of the electric control components.

[0209] It should be pointed out that the connection methods between the wind shield member 37 and the mounting plate 31 include but are not limited to riveting, welding, welding, screw connection or snap connection.

[0211] 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 as to 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.

[0212] 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.

[0213] It should be pointed out that the first air guide plate 361 is inclined 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, thereby reducing the escape of the airflow in the box body 20, and effectively improving the heat exchange effect of the HVAC equipment outdoor unit 100.

[0214] In some embodiments of the present invention, Figures 16 to 22 As shown, the first side plate 32 includes a first horizontal plate body 321 and a first vertical plate body 322, the first horizontal plate body 321 is vertically connected to the first vertical plate body 322, the mounting plate 31 includes a second horizontal plate body 312 and a second vertical plate body 311, the second horizontal plate body 312 is vertically connected to the second vertical plate body 311.

At this time, the first horizontal plate body 321, the second horizontal plate body 312, the second vertical plate body 311 and the first side plate 32 form an installation space for the first air duct 3011.

Among them, the first vertical plate body 322 of the first side plate 32 is provided with a first air inlet 3221, and the second horizontal plate body 312 of the mounting plate 31 is provided with a second air inlet 3121.

[0216] By setting the mounting plate 31, the first side plate 32, the second side plate 33, the third side plate 36 and the 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 blade 13, after the external air flow enters the second air duct 3012 through the first air inlet 3221, a part of it flows along the second air duct 3012 and is discharged through the first air outlet, and the other part 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 form of the first air duct 3011 and the second air duct 3012 can improve the smoothness of the air flow on the basis of simplifying the structure, thereby realizing effective heat dissipation of the electronic control components.

[0217] It should be noted that, in the embodiments of the present invention, Fig.16 and Fig. 22 As shown, 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 airflow enters the second air duct 3012 through the first air inlet 3221, the airflow 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.

[0218] 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.

[0219] In some embodiments of the present invention, Fig.18 as well as Fig. 20 As shown, the first air inlet 3221 includes a first louver hole, the number of the first louver holes is plural, and a first guide portion is arranged at a part of the hole openings of the first louver holes, wherein the first guide portion is connected to the hole openings on one side of the first horizontal plate body 321 of the first louver hole close to the first side plate 32, and an acute angle is formed between the first vertical plate body 322 and the first guide portion.

[0220] Specifically, along the vertical direction, one end of the first air guide is connected to the hole on the upper side of the first louver hole (the hole on one side close to the first horizontal plate body 321), and the other end of the first air guide is set at an acute angle with the first vertical plate body 322. The first air guide can be located inside the second air duct 3012 or outside the second air duct 3012.

The structure of the first louver hole is set so that the oblique lower side of the first air inlet 3221 can be realized, thereby reducing the situation where foreign matter such as rainwater enters through the first air inlet 3221, and reducing the adverse effects of foreign matter such as rainwater on the outdoor unit 100 of the HVAC equipment.

[0221] It should be pointed out that, along the vertical direction, the cross-section of the first louver hole is a fan-shaped structure.

[0222] 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.

The second air guide 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 accompanying drawings of the present invention show that the second air guide 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, 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, the airflow in the second air duct 3012 can be effectively guided to 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.

The third air guide can be located on the inner side of the first air duct 3011 or on the outer side of the second air duct 3012.
