Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning (HVAC) equipment, in particular to an outdoor unit of HVAC equipment and HVAC equipment. Background Art

[0002] The information provided in this part is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] In the existing outdoor unit of HVAC equipment, its top cover assembly integrates corresponding functional components (such as a fan, etc.), and the corresponding functional components operate to meet the operating requirements of the HVAC equipment. When the outdoor unit of HVAC equipment is operating, the blades rotate to achieve heat exchange between the heat exchanger and the external air flow.

[0004] In the prior art, an air flow stagnation area is likely to appear in the outdoor unit of HVAC equipment, resulting in poor heat exchange effect of the outdoor unit of HVAC equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to at least solve the technical problem of poor heat exchange effect of the existing outdoor unit of HVAC equipment. This purpose is achieved by the following technical solutions:

[0006] The utility model provides an outdoor unit of HVAC equipment, comprising:

[0007] A box body;

[0008] A heat exchanger, which is arranged in the box body;

[0009] An electric control box assembly, which is installed on the box body and has a heat dissipation air duct. The interior of the box body is communicated with the outside through the heat dissipation air duct. The heat dissipation air duct has a first air inlet and a first air outlet;

[0010] A top cover assembly, which is installed on the top of the box body and includes blades. The interior of the box body is communicated with the outside through the top cover assembly. The blades are rotatably arranged above the heat exchanger and are used for driving the external air flow to enter the heat dissipation air duct through the first air inlet, and then enter the interior of the box body through the first air outlet, and for driving the air flow inside the box body to be discharged to the outside through the top cover assembly;

[0011] Wherein, along the height direction of the box body, the minimum distance from the first air inlet to the first air outlet is H1, the minimum distance from the first air outlet to the top cover assembly is H2, and the ratio of H2 to H1 is between 0.1 and 0.5.

[0012] According to the HVAC equipment outdoor unit of the present invention, the top cover assembly is arranged on the top of the box body, and the heat exchanger is arranged inside the box body. At this time, the top cover assembly is located on the outside of the heat exchanger, and the blades are arranged above the heat exchanger, that is, the blades are arranged on the outside of the heat exchanger, so that the size of the blades is not limited by the structural size of the heat exchanger. By increasing the size of the blades, the driving ability of the blades on the airflow is improved, thereby reducing the problem of airflow stagnation area in the HVAC equipment outdoor unit, so that the heat exchange effect of the HVAC equipment outdoor unit is effectively improved. At the same time, the interior of the box body is connected with the outside through the heat dissipation duct of the electric control box assembly. Driven by the blades, the airflow enters the heat dissipation duct to achieve heat dissipation of the electric control box assembly, further reducing the problem of airflow stagnation area in the HVAC equipment outdoor unit. Furthermore, by limiting the proportional relationship between the minimum distance from the first air outlet to the top cover assembly and the minimum distance from the first air inlet to the first air outlet, the first air outlet of the heat dissipation duct is at a moderate distance from the top cover assembly, thereby preventing the first air outlet from being too far away from the blades, resulting in insufficient suction force on the heat dissipation duct due to the rotation of the blades, and preventing the first air outlet from being too far away from the blades or too close to the blades, resulting in excessive suction force on the heat dissipation duct due to the rotation of the blades and weakening the heat dissipation effect on other areas inside the box, such as the heat exchanger area, thereby ensuring that the outdoor unit of the HVAC equipment has a good heat exchange effect.

[0023] In some embodiments of the present utility model, a first air inlet is provided on the first side plate.

[0025] In some embodiments of the present utility model, the box body further includes a wind hood member having a third air outlet. The wind hood member is mounted on the mounting plate and is on the same side of the mounting plate as the third side plate. The wind hood member and the mounting plate enclose a wind guiding cavity communicated with the second air outlet.

At this time, the top cover assembly is located outside the heat exchanger, and the blades are arranged above the heat exchanger, that is, outside the heat exchanger. This enables the size of the blades to be unrestricted by the structural size of the heat exchanger. By increasing the size of the blades, the driving ability of the blades for the air flow is improved, thereby reducing the problem of air flow stagnation areas in the HVAC outdoor unit, and effectively improving the heat exchange effect of the HVAC outdoor unit. At the same time, the inside of the box body is communicated with the outside through the heat dissipation air duct of the electronic control box assembly. Driven by the blades, the air flow can enter the heat dissipation air duct to dissipate heat from the electronic control box assembly, further reducing the problem of air flow stagnation areas in the HVAC outdoor unit. Moreover, by defining the proportional relationship between the minimum distance from the first air outlet to the top cover assembly and the minimum distance from the first air inlet to the first air outlet, the distance between the first air outlet of the heat dissipation air duct and the top cover assembly is appropriate, avoiding insufficient suction of the heat dissipation air duct caused by too far a distance when the blades rotate, and weakening the heat dissipation effect on other areas inside the box body due to too close a distance resulting in excessive suction of the heat dissipation air duct by the rotating blades.

[0065] The exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0066] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0067] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly dictates otherwise, terms such as "first", "second", and other numerical terms when used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are to be interpreted accordingly.

[0069] As Figures 1 to 23As shown in the figure, a first aspect of the present utility model provides an outdoor unit 100 of a heating, ventilation and air conditioning (HVAC) device, which includes a box body 20, a heat exchanger 40, an electric control box assembly 30 and a top cover assembly 10. The heat exchanger 40 is disposed inside the box body 20. The electric control box assembly 30 is installed on the box body 20 and has a heat dissipation air duct 301. The interior of the box body 20 communicates with the outside through the heat dissipation air duct 301. The heat dissipation air duct 301 has a first air inlet 3221 and a first air outlet 3222. The top cover assembly 10 is installed on the top of the box body 20 and includes blades 13. The interior of the box body 20 communicates with the outside through the top cover assembly 10. The blades 13 are rotatably disposed above the heat exchanger 40 and are used to drive the outside air flow to enter the heat dissipation air duct 301 through the first air inlet 3221, enter the interior of the box body 20 through the first air outlet 3222, and drive the air flow inside the box body 20 to be discharged to the outside through the top cover assembly 10. Wherein, along the height direction of the box body 20 ( Figure 2 in the F direction shown in the figure), the minimum distance from the first air inlet 3221 to the first air outlet 3222 is H1, and the minimum distance from the first air outlet 3222 to the top cover assembly is H2. The ratio of H2 to H1 is between 0.1 and 0.5.

[0070] 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 40. The blades 13 of the top cover assembly 10 are located above the heat exchanger 40. At this time, the blades 13 are located outside the heat exchanger 40. The electric control box assembly 30 has a heat dissipation air duct 301. One end of the heat dissipation air duct 301 is communicated with the outside, and the other end of the heat dissipation air duct 301 is communicated with the interior of the box body 20. The blades 13 can rotate, and the rotation of the blades 13 drives the air flow, enabling the outside air flow to enter the interior of the box body 20 through the heat dissipation air duct 301. At the same time, the air flow inside the box body 20 can exchange heat with the heat exchanger 40 and then be discharged to the outside through the top cover assembly 10.

[0071] In the prior art, the heat exchanger 40 is arranged in a ring shape on the radial outside of the blades 13. At this time, the diameter of the blades 13 is limited by the structural shape of the heat exchanger 40. At this time, the driving ability of the blades 13 for the air flow is limited.

[0072] In the embodiments of the present invention, as shown in Figure 2 and Figure 16As shown in the figure, the blade 13 is arranged above the heat exchanger 40, that is, the blade 13 is arranged outside 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 for the air flow is improved, thereby reducing the problem of air flow stagnation area in the outdoor unit 100 of the HVAC equipment, and effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment. At the same time, the inside of the box body 20 can be communicated with the outside through the heat dissipation air duct 301 of the electronic control box assembly 30. Driven by the blade 13, the air flow can enter the heat dissipation air duct 301 to realize the heat dissipation of the electronic control box assembly 30, further reducing the problem of air flow stagnation area in the outdoor unit 100 of the HVAC equipment.

[0073] It should be noted that in the embodiment of the present invention, the electronic control box assembly 30 is used to control the outdoor unit 100 of the HVAC equipment accordingly. Among them, the control methods include but are not limited to power on, power off, and working mode switching, etc. The electronic control box assembly will generate heat during operation. If the electronic control box assembly 30 is not effectively cooled, the electronic control box assembly 30 will malfunction due to overheating, which will further affect the operation of the outdoor unit 100 of the HVAC equipment.

[0074] According to the outdoor unit 100 of the HVAC equipment of the present invention, the top cover assembly 10 is arranged on the top of the box body 20, the heat exchanger 40 is arranged inside the box body 20. At this time, the top cover assembly 10 is located outside the heat exchanger 40, and the blade 13 is arranged above the heat exchanger 40, that is, the blade 13 is arranged outside 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 for the air flow is improved, thereby reducing the problem of air flow stagnation area in the outdoor unit 100 of the HVAC equipment, and effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment. At the same time, the inside of the box body 20 is communicated with the outside through the heat dissipation air duct 301 of the electronic control box assembly 30. Driven by the blade 13, the air flow enters the heat dissipation air duct 301 to realize the heat dissipation of the electronic control box assembly 30, further reducing the problem of air flow stagnation area in the outdoor unit 100 of the HVAC equipment. And by defining the proportional relationship between the minimum distance from the first air outlet 3222 to the top cover assembly 10 and the minimum distance from the first air inlet 3221 to the first air outlet 3222, the distance from the first air outlet 3222 of the heat dissipation air duct 301 to the top cover assembly 10 is made appropriate, avoiding insufficient suction of the blade 13 rotation on the heat dissipation air duct 301 due to too far distance, and weakening the heat dissipation effect on other areas inside the box body 20 due to too close distance and too large suction of the blade 13 rotation on the heat dissipation air duct 301.

[0075] In some embodiments of the present invention, the outdoor unit 100 of the HVAC equipment further includes a compressor assembly 50. The compressor assembly 50 includes a compressor, which may be an ejector enhanced compressor 51. Along the radial direction of the ejector enhanced compressor 51, the ejector enhanced compressor 51 is spaced apart from the electric control box assembly 30.

[0076] It should be understood that in the existing outdoor unit of HVAC equipment, the compressor is usually arranged below the electric control component. The heat generated by the compressor is not easily dissipated, and it has an adverse impact on the electric control component. The compressor assembly 50 of the present utility model can be fixed on the bottom plate of the box body 20. Specifically, it can be fixed by snap fasteners, bolts or brackets. The compressor assembly 50 includes an ejector enhanced compressor 51 and supporting pipelines, heat exchangers and other components. The ejector enhanced compressor 51 generates a large amount of heat during use. Therefore, the ejector enhanced compressor 51 and the electric control box assembly 30 can be arranged at intervals in the radial direction. That is, after the position of the box body 20 is fixed, the ejector enhanced compressor 51 and the electric control box assembly 30 are arranged at intervals in the horizontal direction, so that the suction force generated by the top cover assembly 10 sucks external air into the box body 21 from the side of the box body 20, and dissipates heat from both sides to the electric control box assembly 30 and the ejector enhanced compressor 51 respectively, so that the heat generated by the ejector enhanced compressor 51 can be quickly taken away, improving the heat dissipation effect.

[0077] In some embodiments of the present invention, along the height direction of the box body 20, the first air inlet 3221 is located at the bottom end of the electric control box assembly 30, and the minimum distance from the bottom end of the electric control box assembly 30 to the bottom end of the compressor is H3, and the ratio of H3 to H1 is between 0.1 and 0.5.

[0078] It should be understood that taking the ejector enhanced compressor 51 as an example of the compressor, along the height direction of the box body 20, there is a certain distance from the bottom end of the electric control box assembly 30 to the bottom end of the ejector enhanced compressor 51, so that there is a certain space between the bottom end of the electric control box assembly 30 and the bottom end of the ejector enhanced compressor 51, which is convenient for the pipeline layout of the compressor assembly 50. At the same time, there is a certain height between the first air inlet 3221 and the plane where the outdoor unit 100 of the HVAC equipment is placed, reducing the phenomenon of external dust and accumulated water entering the first air inlet, and improving the reliability of the outdoor unit 100 of the HVAC equipment. Specifically, the ratio of H3 to H1 is between 0.1 and 0.5, making both the structural compactness and the equipment reliability achieved.

[0079] In some embodiments of the present invention, the top cover assembly 10 includes a wind guide cover 15 and a top cover body 14 having a receiving space. Among them, the top of the box body 20 is connected to the top cover body 14, the wind guide cover 15 is arranged in the receiving space and is fixedly connected to the top cover body 14, and the blades 13 are arranged in the wind guide channel 155 of the wind guide cover 15.

[0080] Specifically, the top cover assembly 10 includes a wind guide cover 15, blades 13, and a top cover body 14 having a receiving space. The top cover body 14 is disposed outside the box body 20 and fixedly connected to the top of the box body 20. The wind guide cover 15 is disposed in the receiving space of the top cover body 14, and the blades 13 are disposed in the wind guide channel 155 of the wind guide cover 15 and can rotate relative to the wind guide channel 155. Among them, the outside can communicate with the heat exchanger 40 through the wind guide channel 155.

[0081] As Figure 1 and Figure 3 shown, by disposing the top cover body 14 on the top of the box body 20 and the heat exchanger 40 inside the box body 20, at this time, the top cover body 14 is located outside the heat exchanger 40, the wind guide cover 15 is disposed in the receiving space of the top cover body 14, and the blades 13 are disposed in the wind guide channel 155 of the wind guide cover 15. At this time, the blades 13 are disposed outside 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 for the air flow is improved, thereby reducing the problem of the occurrence of air flow stagnation areas in the outdoor unit 100 of the HVAC equipment, and effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0082] It should be understood that the wind guide channel 155 has an air inlet and an air outlet. When the blades 13 rotate in the wind guide channel 155, the air flow can be driven, so that the air flow enters the wind guide channel 155 through the air inlet, and the air flow in the wind guide channel 155 is discharged from the air outlet of the wind guide channel 155.

[0083] It should be noted that when the blades 13 rotate, under the drive of the blades 13, the flow direction of the air flow can be from the heat exchanger 40 to the blades 13, and the flow direction of the air flow can also be from the blades 13 to the heat exchanger 40. In the embodiment of the present invention, the flow direction of the air flow is from the heat exchanger 40 to the blades 13, that is, the air flow at the position of the heat exchanger 40 is drawn away by the rotation of the blades 13, so that the air flow after heat exchange with the heat exchanger 40 is drawn out and the air flow that has not undergone heat exchange flows to the position of the heat exchanger 40 to realize heat exchange between the flowing air flow and the heat exchanger 40.

[0084] In addition, the blades 13 can be metal parts or non-metal parts. In the embodiment of the present invention, the blades 13 are non-metal parts, such as plastic or carbon fiber, etc., and can be processed and manufactured by an integral molding method, thereby improving the processing efficiency.

[0085] It should be noted that as Figure 3As 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the top cover body 14 is provided with a top surface and a first communication port 143, the top surface is arranged away from the first communication port 143, and 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 box body 20 of the HVAC equipment outdoor unit 100 is plugged into the first communication port 143.

[0089] 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.

[0090] 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.

[0091] In some embodiments of the present invention, Figure 6As shown, a second communication port 144 is formed on the top surface of the top cover body 14. At this time, the second communication port 144 and the first communication port 143 are located on opposite sides of the top cover body 14. The air guide cover 15 is arranged in the accommodation space of the top cover body 14. One end of the air guide channel 155 of the air guide cover 15 is communicated with the first communication port 143, and the other end is communicated with the outside through the second communication port 144.

[0092] Among them, the top cover assembly 10 is arranged on the top of the box body 20 of the outdoor unit 100 of the heating and ventilation equipment. The first communication port 143 of the top cover body 14 is in plug-in fit with the top of the outdoor unit. The inside of the box body 20 is communicated with the accommodation space of the top cover body 14 through the first communication hole, and is communicated with the outside through the second communication port 144.

[0093] Specifically, the second communication port 144 is arranged on the top cover body 14 so that the box body 20 can be communicated with the outside through the first communication port 143 and the second communication port 144, so that the external air flow can exchange heat with the working components inside the box body 20, thereby meeting the normal operation requirements of the outdoor unit 100 of the heating and ventilation equipment.

[0094] It should be understood that the first communication port 143 and the second communication port 144 are formed on opposite sides of the top cover body 14, so that the air flow can flow in a straight line when flowing on the top cover body 14, reducing the influence on the air flow velocity and improving the heat exchange efficiency of the outdoor unit 100 of the heating and ventilation equipment.

[0095] It should be noted that the top of the box body 20 of the heating and ventilation equipment is an open structure. The first communication port 143 is communicated with the open structure at the top of the box body 20. The inside of the box body 20 is communicated with the outside through the first communication port 143, the inside of the top cover body 14 and the second communication port 144.

[0096] In addition, the orifice shape of the first communication port 143 includes but is not limited to circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc.; similarly, the orifice shape of the second communication port 144 includes but is not limited to circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc.

[0097] In addition, the area of the flow cross-section of the first communication port 143 and the area of the flow cross-section of the second communication port 144 can be equal or unequal.

[0098] In some embodiments of the present invention, in the top cover assembly 10, there is also a mesh cover 11 installed on the top cover body 14, wherein the second communication port 144 on the top cover body 14 is blocked by the mesh cover 11. By providing the mesh cover 11 at the second communication port 144, while enabling air flow exchange between the second communication port 144 and the outside, the blocking of the second communication port 144 is achieved, thereby reducing the situation where external foreign objects fall into the interior of the top cover body 14 and the interior of the box body 20 through the second communication port 144.

[0099] It should be noted that the mesh cover 11 is fixedly connected to the top cover body 14, and the connection and fixation methods include but are not limited to screw connection, snap connection, buckle connection, riveting, bonding, welding, etc.

[0100] In addition, the mesh cover 11 can be a metal part, and can be processed by welding or casting during processing; the mesh cover 11 can also be a non-metal part, such as plastic, and can be integrally formed by injection molding during processing.

[0101] Furthermore, the mesh cover 11 has mesh holes, and the shapes of the mesh holes include but are not limited to circular, square, pentagonal, hexagonal, triangular, oval, diamond, etc.

[0102] In some embodiments of the present invention, as Figure 6 and Figure 10 shown, the side of the top cover body 14 facing away from the first communication port 143 is the top surface, and a groove 145 is formed on the top surface. Among them, the second communication port 144 is formed on the bottom surface of the groove 145. At the same time, the first communication port 143 and the second communication port 144 are arranged opposite to each other. At least a part of the body of the mesh cover 11 is received in the groove 145 in the direction from the first communication port 143 to the second communication port 144 and abuts against the bottom surface of the groove 145.

[0103] Specifically, the shape of the groove 145 is adapted to the shape of the mesh cover 11. By providing the groove 145, the mesh cover 11 is limited by the groove 145, realizing the positioning and installation of the mesh cover 11, thereby improving the installation accuracy of the mesh cover 11.

[0104] It should be understood that in the direction from the first communication port 143 to the second communication port 144, part of the body of the mesh cover 11 can be arranged in the receiving groove, or the entire body can be arranged in the receiving groove.

[0105] In addition, by providing the groove 145 on the top surface of the top cover body 14, with the change in structure, the strength of the top cover body 14 is further enhanced, thereby further improving the overall structural strength of the top cover body 14.

[0106] It should be noted that reinforcing ribs 1422 are provided on the bottom surface of the groove 145. By using the reinforcing ribs 1422, the strength of the bottom surface can be increased, thereby increasing the overall strength of the top cover assembly 10. In addition, the reinforcing ribs 1422 include, but are not limited to, rib plates, convex structures, or concave structures, etc.

[0107] In some embodiments of the present invention, as Figure 3 and Figure 5 shown, the top cover assembly 10 further includes a driving member 12. Among them, the mesh cover 11 of the top cover assembly 10 has a side facing the second communication port 144, and the driving member 12 is fixedly installed on this side. The blade 13 is connected to the driving shaft of the driving member 12 and is rotatably arranged in the air guiding channel 155 of the air guiding cover 15.

[0108] Specifically, when the outdoor unit 100 of the heating and ventilation equipment operates, the driving member 12 rotates and drives the blade 13 to rotate. During the rotation of the blade 13, the air flow is caused to flow from the first communication port 143 to the second communication port 144, or the air flow is caused to flow from the second communication port 144 to the first communication port 143. The driving of the air flow is realized by using the blade 13 and the driving member 12, thereby improving the heat exchange efficiency of the outdoor unit 100 of the heating and ventilation equipment.

[0109] Furthermore, the mesh cover 11 is installed in the groove 145 at the top of the top cover body 14. By using the groove 145 to limit the installation position of the mesh cover 11, 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.

[0110] It should be understood that in the invention, the blade 13 and the driving member 12 form an axial flow fan structure, that is, the air flow enters and exits along the axis of the blade 13. In addition, in the invention, under the drive of the blade 13 and the driving member 12, the air flow flows from one side of the first communication port 143 to one side of the second communication port 144.

[0111] It should be noted that in the invention, the connection manner between the driving member 12 and the mesh cover 11 includes, but is not limited to, screw connection, snap connection, bonding, welding, riveting, etc. At the same time, the blade 13, the first communication port 143, and the second communication port 144 are coaxially arranged.

[0112] In addition, the driving member 12 includes, but is not limited to, a motor or a starting motor, etc.

[0113] In some embodiments of the present invention, the top cover body 14 is an integral structure, and the integral top cover body 14 is integrally formed and processed.

[0114] In some embodiments of the present invention, as Figure 14 and Figure 15As 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.

[0115] 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.

[0116] 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 .

[0117] 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.

[0118] When there are multiple side panels 142 (two or more), a cylindrical structure is formed by assembling all side panels 142 (the connection methods of 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.

[0119] 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 ).

[0120] 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 ).

[0121] 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.

[0122] By providing the flanging 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.

[0123] In some embodiments of the present invention, as Figures 7 to 9 shown, the air guide cover 15 includes a main body portion 151 and a shielding portion 152. Among them, the main body portion 151 is arranged in 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 communicated with the opposite ends of the cylindrical structure. The shielding portion 152 is connected to the outer peripheral surface of the main body portion 151, and the shielding portion 152 is correspondingly arranged at the corner positions of the top cover body 14 of the cylindrical structure, and one shielding portion 152 is arranged at each corner position, and the space between the top cover body 14 of the cylindrical structure and the main body portion 151 is shielded by the shielding portion 152.

[0124] Specifically, the top cover body 14 is in 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 portions 152 in the present invention is also four. The four shielding portions 152 are arranged at intervals along the circumferential direction of the outer peripheral surface of the main body portion 151 of the cylindrical structure, and one shielding portion 152 is correspondingly arranged at each corner of the top cover body 14. By providing the shielding portion 152, the space between the top cover body 14 of the cylindrical structure and the main body portion 151 can be shielded, and the situation of air flow entering between the top cover body 14 and the air guide cover 15 can be reduced (the air flow entering between the two is prone to stagnation), so that the situation of air flow stagnation areas in the outdoor unit 100 of the HVAC equipment is reduced, and the heat exchange effect of the outdoor unit 100 of the HVAC equipment is improved.

[0125] It should be understood that the shielding portion 152 and the main body portion 151 can be an integral structure or a split structure. When the shielding portion 152 and the main body portion 151 are an integral structure, they can be processed and manufactured by an integral molding method. When the shielding portion 152 and the main body portion 151 are a split structure, they are processed separately first, and then the two are connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0126] It should be noted that along the axial direction of the main body portion 151 of the cylindrical structure, all the shielding portions 152 can be located on the same circumferential surface or arranged at intervals. In the embodiment of the present invention, all the shielding portions 152 are located on the same circumferential surface, so that the structural stability of the air guide cover 15 reaches the optimal effect, and the situation of the air guide cover 15 shaking caused by the rotation of the blade 13 is reduced.

[0127] In addition, the shielding portion 152 may or may not be connected to the inner wall of the top cover body 14 (the inner surface of the accommodation space). When they are connected, the shielding portion 152 is arranged in contact with the inner wall of the top cover body 14 and is connected by bonding, screw connection, welding, riveting or snap connection. When they are not connected, the shielding portion 152 is just arranged in contact 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.

[0128] Further, the air guiding channel 155 in the air guiding cover 15 can be a straight channel or a bent channel. In the embodiment of the present invention, the air guiding cover 15 has a cylindrical structure, and both ends of the cylindrical structure are open structures. At this time, the air guiding channel 155 is a straight channel structure. One open end of the cylindrical structure is for air intake, and the other open end of the cylindrical structure is for air outlet.

[0129] Further, in the axial direction of the blade 13, the size of the air guiding 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 guiding channel 155, and further, the driving ability of the blade 13 for the air flow is further enhanced.

[0130] In some embodiments of the invention, as Figure 9 shown, a wire passing hole 156 for passing the connection wire of the driving member 12 is provided on the air guiding cover 15. By providing the wire passing hole 156, it is convenient to lead out the connection wire of the driving member 12, improving the convenience of assembly, and further effectively improving the assembly efficiency.

[0131] It should be noted that the wire passing hole 156 includes but is not limited to a round hole, a square hole, a rhombic hole, a triangular hole, an oval hole, a pentagonal hole or a hexagonal hole, etc.

[0132] The wire passing hole 156 is opened on the side wall of the air guiding cover 15 and is arranged close to the driving member 12 to reduce the length of the connection wire in the air guiding channel 155 of the air guiding cover 15 and reduce the influence of the connection wire on the air guiding channel 155.

[0133] In some embodiments of the present invention, as Figures 7 to 9 shown, the air guiding cover 15 further includes a connecting portion 153 connected to the outer peripheral surface of the main body portion 151. The shielding portion 152 and the connecting portion 153 are arranged at intervals along the axial direction of the cylindrical structure. The connection methods between the top cover body 14 of the cylindrical structure and the inner wall of the connecting portion 153 include welding, bonding, snap connection, riveting or screw connection.

[0134] Specifically, a connecting portion 153 is provided. The air guide cover 15 is connected and fixed to the top cover body 14 by means of the connecting portion 153, so that the two form an integral structure, thereby improving the overall strength and reducing the shaking of the blade 13 caused by poor structural strength during rotation, thereby improving the running stability of the blade 13, and further effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0135] In addition, by setting the connection mode between the connecting portion 153 and the top cover body 14, the connection mode between the two can be set according to specific requirements, improving the flexibility of assembly. As a specific implementation manner, in the present invention, the air guide cover 15 is adhesively fixed to the top cover body 14. The adhesive connection method is convenient for assembly and the connection position has good structural strength, which can effectively meet the usage requirements.

[0136] It should be understood that the connecting portion 153 and the main body portion 151 can be of an integral structure or a split structure. When the connecting portion 153 and the main body portion 151 are of an integral structure, they can be processed and manufactured by an integral molding method. When the connecting portion 153 and the main body portion 151 are of a split structure, they are first processed separately, and then the two are connected and fixed by means of bonding, screw connection, welding, riveting or clamping.

[0137] In some embodiments of the present invention, as Figure 7 and Figure 8 shown, a reinforcing portion 154 is further provided on the air guide cover 15. Among them, the reinforcing portion 154 is provided on at least one of the shielding portion 152, the connecting portion 153, the main body portion 151, the connection position between the main body portion 151 and the connecting portion 153, and the connection position between the main body portion 151 and the shielding portion 152.

[0138] Specifically, the air guide cover 15 and the blade 13 are coaxially arranged. By providing the reinforcing 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, and the stability of the air flow formed by the blade 13 is improved, thereby improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0139] It should be noted that in the embodiments of the present invention, the reinforcing portion 154 is provided at each of the shielding portion 152, the connecting portion 153, the main body portion 151, the connection position between the main body portion 151 and the connecting portion 153, and the connection position between the main body portion 151 and the shielding portion 152, so as to improve the structural strength of the air guide cover 15 as a whole.

[0140] In addition, the reinforcing portions 154 are dispersedly arranged on the air guide cover 15, so that the structure of the air guide cover 15 can be further made uniform, and the overall structural strength of the air guide cover 15 can be further improved.

[0141] In some embodiments of the present invention, the reinforcing portion 154 includes at least one of a groove 145, a convex hull, and a rib plate.

[0142] By setting the structure of the reinforcing portion 154, the reinforcing portion 154 can effectively meet the usage requirements. Among them, one of the structures of the groove 145, the convex hull, and the rib plate can be used as the reinforcing portion 154, or two structures can be used as the reinforcing portion 154, or three structures can be used as the reinforcing portion 154.

[0143] In an embodiment of the present invention, the groove 145 and the rib plate are both set as the reinforcing structure 1421, that is, a part of the reinforcing structure 1421 is the groove 145, and another part of the reinforcing 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.

[0144] In some embodiments of the present invention, as Figures 4 to 6 , Figure 12 , Figure 13 , Figure 15 shown, a reinforcing structure 1421 is further provided on the top cover body 14 between the first communication port 143 and the top surface.

[0145] Specifically, the reinforcing structure 1421 is provided between the top surface and the first communication 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 communication port 143. The first communication port 143 of the top cover body 14 is inserted and matched with the top of the box body 20 of the outdoor unit 100 of the heating, ventilation and air conditioning equipment. By providing the reinforcing structure 1421 close to the first communication 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 communication port 143 and the box body 20, and further reducing the situation that the operation of the outdoor unit 100 of the heating, ventilation and air conditioning equipment is adversely affected due to the insufficient structural strength of the top cover assembly 10.

[0146] It should be understood that the top of the box body 20 is inserted and matched with the top cover body 14. If the reinforcing structure 1421 is not provided on the top cover body 14, the self-strength of the top cover body 14 is relatively low, especially the connection position between the top cover body 14 and the box body 20. Therefore, by providing the reinforcing structure 1421 on the top cover body 14 and arranging the reinforcing structure 1421 close to the position of the first communication port 143, the strength and stability of the connection position between the top cover body 14 and the box body 20 can be improved.

[0147] In addition, the strengthening structure 1421 refers to a structure formed on the top cover body 14. This structure can be integrally formed with the top cover body 14 or can be separately processed and then installed and fixed on the top cover body 14. In an embodiment of the present invention, the strengthening structure 1421 is integrally formed with the top cover body 14, thereby being able to reduce the processing procedures and effectively improving the production efficiency.

[0148] It should be noted that by providing the strengthening structure 1421 on the top cover body 14, the air guide cover 15 can be made not to participate in weighing. At this time, 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 as a component formed of plastic or foam.

[0149] In some embodiments of the present invention, the strengthening structure 1421 is provided on the side plate 142 of the top cover body 14, and the strengthening structure 1421 is provided as a convex structure.

[0150] Specifically, the strengthening structure 1421 as a convex structure is formed on the side plate 142 of the top cover body 14. Among them, the strengthening structure 1421 as a convex structure is formed on the outer surface or the inner surface of the top cover body 14. When the convex structure is formed on the outer surface of the top cover body 14, it can be a convex hull structure formed on the outer surface of the top cover body 14, or it can be a convex structure bulging from the inner surface of the top cover body 14 to the outer surface; when the convex structure is formed on the inner surface of the top cover body 14, it can be a convex hull structure formed on the inner surface of the top cover body 14, or it can be a convex structure bulging from the outer surface of the top cover body 14 to the inner surface.

[0151] In addition, the strengthening structure 1421 as a convex structure is provided close to the first communication port 143 of the top cover body 14. Among them, when the convex structure is formed by bulging, a structure adapted to the convex structure is provided at a position corresponding to the strengthening structure 1421 on 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.

[0152] In addition, when the outer surface of the top cover body 14 has a convex structure or a concave structure is formed on the outer surface due to the formation of a convex structure on the inner surface, when installing the top cover assembly 10, the assembler can hold the convex structure or dig with the hand at the position of the concave structure, which improves the convenience of lifting the top cover assembly 10 during assembly and effectively improves the assembly efficiency.

[0153] In some embodiments of the present invention, such as Figures 4 to 6 、 Figure 12 、Figure 13 , Figure 15 As shown in Figure 15 , the strengthening structure 1421 is disposed on the side plate 142 of the top cover body 14, and the strengthening structure 1421 is configured as a concave structure.

[0154] Specifically, the strengthening structure 1421, which is a concave structure, is formed on the side wall of the top cover body 14. Among them, the strengthening structure 1421, which is a concave structure, is formed on the outer surface or the inner surface of the top cover body 14. When the concave 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 a concave structure formed by recessing from the outer surface of the top cover body 14 towards the inner surface; when the convex 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 a concave structure formed by recessing from the inner surface of the top cover body 14 towards the outer surface.

[0155] In addition, the strengthening structure 1421, which is a concave structure, is disposed close to the first communication port 143 of the top cover body 14. Among them, when the concave structure is formed by recessing, a structure adapted to the concave structure is provided at a position corresponding to the strengthening structure 1421 on 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.

[0156] Furthermore, when the outer surface of the top cover body 14 has a groove 145 structure or has a convex structure formed on the outer surface due to the formation of a concave structure on the inner surface, during the installation of the top cover assembly 10, the assembler can hold the convex structure or dig at the position of the concave structure, improving the convenience of lifting the top cover assembly 10 during assembly and effectively enhancing the assembly efficiency.

[0157] In some embodiments of the present invention, the number of the strengthening structures 1421 provided on the top cover body 14 is one. One strengthening structure 1421 is disposed along the circumference of the first communication port 143, and one strengthening structure 1421 can cover a part of the circumference of the first communication port 143 or the entire circumference of the first communication port 143.

[0158] In some embodiments of the present invention, as Figure 5 and 6 shown, a plurality of strengthening structures 1421 are provided on the top cover body 14, and all the strengthening structures 1421 are spaced apart along the circumference of the top cover body 14.

[0159] Specifically, in this embodiment, the number of the strengthening structures 1421 is set to be multiple, so that the strengthening 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 is effectively enhanced by the strengthening structures 1421.

[0160] It should be noted that the multiple strengthening structures 1421 are arranged at intervals along the circumferential direction of the top cover body 14, and the circumferential direction of the top cover body 14 is the same as that of the first communication port 143. Among them, the multiple strengthening structures 1421 can cover a part of the circumferential direction of the first communication port 143 or can cover the entire circumferential direction of the first communication port 143.

[0161] In some embodiments of the present invention, as Figures 16 to 18 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 communicated with the outside, and the other end of the first air duct 3011 is communicated with the inside of the box body 20. One end of the second air duct 3012 is communicated with the outside, and the other end of the second air duct 3012 is communicated with the inside of the box body 20.

[0162] The electronic control box assembly 30 includes a box body and an electronic control component. The box body has an installation space, and the installation space constitutes at least part of the first air duct 3011. The electronic control component is installed inside the installation space, and the second air duct 3012 is arranged outside the installation space.

[0163] When the blades 13 drive the air flow to exchange heat with the outdoor unit 100 of the HVAC equipment, the outside air flow enters the inside of the box body 20 through the first air duct 3011 and the second air duct 3012 respectively, and the air flow inside the box body 20 is discharged through the top cover assembly 10. The outside air flow enters the first air duct 3011 and flows along the first air duct 3011, and the flowing air flow exchanges heat with the electronic control component. At the same time, the outside air flow passes through the second air duct 3012. When the air flow flows in the second air duct 3012, at least part of the electronic control component can exchange heat with the air flow in the second air duct 3012 through the side wall of the installation space. By setting the first air duct 3011 and the second air duct 3012, the effective heat dissipation of the electronic control component can be realized, the situation that the electronic control component fails due to high temperature is reduced, and further the electronic control component can operate stably and efficiently.

[0164] It should be noted that during the operation of the electronic control component, the electronic devices it has generate different amounts of heat due to different functions. For example, devices such as capacitors and inductors generate relatively high amounts of heat, while integrated chips generate relatively low amounts of heat. The air flow in the first air duct 3011 directly enters the position where the electronic control component is located, and the flowing air directly contacts each device of the electronic control component and conducts heat exchange, thereby realizing the heat dissipation of the electronic control component. The second air duct 3012 is arranged outside the installation space and corresponds to the position of the device with relatively high heat generation in the electronic control component. The air flow in the second air duct 3012 exchanges heat with the device with relatively high heat generation in the electronic control component through the side wall of the installation space, thereby realizing the auxiliary heat dissipation of the electronic control component, so that the operating temperature of the electronic control component is maintained below the safe operating temperature, effectively reducing the failure rate of the electronic control component.

[0165] In addition, in the embodiment of the present invention, the installation space of the box body constitutes all of the first air duct 3011, that is, one end of the accommodation space is communicated with the outside, and the other end of the accommodation space is communicated with the inside of the box body 20, thereby forming the first air duct 3011.

[0166] In some embodiments of the present invention, as Figures 19 to 22 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 fixedly connected to the box body 20, the first side plate 32 is fixedly connected to the bottom of the mounting plate 31, and the second side plate 33 and the third side plate 36 are fixedly connected to opposite sides of the mounting plate 31. Among them, part of the structures of the mounting plate 31, the second side plate 33, and the first side plate 32 together enclose the installation space, and the electronic control component is arranged in the installation space and fixedly connected to the mounting plate 31. The mounting plate 31 and the third side plate 36 enclose the second air duct 3012.

[0167] The mounting plate 31, the first side plate 32, the second side plate 33, and the third side plate 36 are assembled to form the box body structure. The overall structure is simple and can be processed separately and then assembled, thereby simplifying the processing difficulty and effectively reducing the manufacturing cost.

[0168] It should be understood that when the air flow passes through the second air duct 3012, the air flow in the second air duct 3012 exchanges heat with the electronic control component through the mounting plate 31 to realize the heat dissipation of the electronic control component.

[0169] It should be noted 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 supplement to the installation position of the box body 20, so that after the electronic control box component 30 is installed on the box body 20, the coordination of the overall external contour of the box body 20 can be improved.

[0170] In addition, the materials of the mounting plate 31, the first side plate 32, the second side plate 33, and the third side plate 36 can all be the same, partially the same, or all different. In the embodiments 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 completely the same, and can be metal parts (such as stainless steel parts, etc.) or non-metal parts (such as plastic parts, etc.).

[0171] In addition, the connection methods between the first side plate 32 and the mounting plate 31 include but are not limited to riveting, welding, screw connection, or snap connection. The connection methods between the second side plate 33 and the mounting plate 31 include but are not limited to riveting, welding, screw connection, or snap connection. The connection methods between the third side plate 36 and the mounting plate 31 include but are not limited to riveting, welding, screw connection, or snap connection.

[0172] In some embodiments of the present invention, as Figures 19 to 20 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 fixedly connected to the mounting plate 31, and there is a space between the main control board 34 and the communication control board 35.

[0173] Specifically, the communication control board 35 is used for communicating with the wire controller of the HVAC equipment to receive the control signal of the wire controller. In the prior art, the communication control board is externally disposed, that is, the communication control board 35 is installed outside the box body 20. After long-term use, the fixing structure of the communication control board 35 will age. When the aged fixing structure is subjected to external forces (such as vibration or extrusion, etc.), it will break, resulting in the situation that the communication control board 35 falls off and is damaged. In the embodiments of the present invention, the communication control board 35 is built into the installation space of the box body, thereby reducing the problem that the fixing structure of the communication control board 35 is prone to aging when it is exposed, and further reducing the situation that the communication control board 35 falls off and is damaged.

[0174] 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 spaced apart 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 assembly. At the same time, the main control board 34 and the communication control board 35 are spaced apart in the installation space, so that the fluidity of the air flow passing through the installation space (the first air duct 3011) is better, reducing the problem of the occurrence of air flow stagnant areas, and further improving the heat dissipation effect of the electric control assembly.

[0175] It should be noted that the communication control board 35 can be directly fixed on the mounting plate 31 of the box body, or can be fixed on the mounting plate 31 of the box body through a fixing bracket.

[0176] In addition, the main control board 34 is fixedly connected to the mounting board 31 of the box body. The main control board 34 and the mounting board 31 are connected and fixed by connecting columns, so that there is a gap between the main control board 34 and the mounting board 31, enabling air flow to pass through between the main control board 34 and the mounting board 31. Furthermore, the contact area between the air flow and the main control board 34 is increased, effectively improving the heat exchange effect of the main control board 34.

[0177] In some embodiments of the present invention, as Figure 22 shown, in the electric control box assembly 30, there is also a heat dissipation member 38 disposed in the second air duct 3012. Among them, the heat dissipation member 38 is fixedly connected to the mounting board 31, and the main control board 34 is correspondingly arranged with the heat dissipation member 38. The main control board 34 can be thermally connected to the heat dissipation member 38 through the mounting board 31.

[0178] Specifically, when the outdoor unit 100 of the HVAC equipment operates, the blades 13 rotate, causing the outside air flow to enter the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 exchanges heat with the main control board 34 and the communication control board 35 of the electric control assembly. After the heat exchange, the air flow 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 dissipation member 38 and the mounting board 31 of the box body. After the heat exchange, the air flow enters the box body 20. The air flow in the box body 20 is discharged to the outside through the top cover assembly 10 under the drive of the blades 13.

[0179] By setting the heat dissipation member 38, the contact area with the air flow in the second air duct 3012 is increased, further improving the heat dissipation efficiency and keeping the temperature of the electric control assembly within the safe operating range.

[0180] It should be noted that in the embodiments of the present invention, the heat dissipation member 38 is in a fin structure. The heat dissipation member 38 in the fin structure has a large extension area, which can increase the contact area with the air flow and further improve the heat dissipation efficiency.

[0181] In addition, a heat-conducting medium (such as heat-conducting silicone grease, etc.) can be filled between the heat dissipation member 38 and the mounting board 31, which can improve the heat conduction efficiency between the heat dissipation member 38 and the mounting board 31 and further enhance the heat dissipation effect on the main control board 34.

[0182] In some embodiments of the present invention, as Figures 16 to 22As shown in the figure, a first air inlet 3221 is formed on the first side plate 32 of the box body. The mounting plate 31 and the third side plate 36 of the box body enclose a first air outlet 3222. The first air inlet 3221 is located below the first air outlet 3222. The outside is communicated with one end of the second air duct 3012 through the first air inlet 3221, and the inside of the box body 20 is communicated with the other end of the second air duct 3012 through the first air outlet 3222. A second air inlet 3121 and a second air outlet 3111 are formed on the mounting plate 31 of the box body. Among them, the second air inlet 3121 is located below the second air outlet 3111. The outside is communicated with one end of the first air duct 3011 through the second air inlet 3121, and the inside of the box body 20 is communicated with the other end of the first air duct 3011 through the second air outlet 3111.

[0183] By setting the first air inlet 3221 and the first air outlet 3222, the structure of the second air duct 3012 with air inlet from the bottom and air outlet from the top is realized, thus reducing the situation that rainwater and other foreign objects enter the inside of the box body 20 through the second air duct 3012, and further reducing the situation of failure of the outdoor unit 100 of the heating and ventilation equipment caused by foreign objects entering the inside of the box body 20.

[0184] 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 from the bottom and air outlet from the top is also realized, thus reducing the situation that rainwater and other foreign objects enter the inside of the box body 20 through the first air duct 3011, and further reducing the situation of failure of the outdoor unit 100 of the heating and ventilation equipment caused by foreign objects entering the inside of the box body 20.

[0185] In some embodiments of the present invention, as Figure 17 、 Figure 21 and Figure 22 shown, the box body further includes a wind hood member 37. A third air outlet 372 is formed on the wind hood member 37. The wind hood member 37 is fixedly connected to the mounting plate 31 of the box body. The third side plate 36 and the wind hood member 37 are located on the same side of the mounting plate 31. The mounting plate 31 and the wind hood member 37 enclose a wind guiding cavity. The wind guiding cavity is communicated with the first air duct 3011 through the second air outlet 3111, and the wind guiding cavity is communicated with the inside of the box body 20 through the third air outlet 372. Along the vertical direction, the third air outlet 372 is located between the second air outlet 3111 and the first air outlet 3222. Among them, the second air outlet 3111 is spaced above the third air outlet 372, and the first air outlet 3222 is spaced below the third air outlet 372.

[0186] Specifically, when the outdoor unit 100 of the HVAC equipment operates, the blades 13 rotate, enabling the outside air flow to enter the first air duct 3011 and the second air duct 3012 respectively. The air flow entering the first air duct 3011 exchanges heat with the main control board 34 and the communication control board 35 of the electronic control assembly. After heat exchange, the air flow passes through the second air outlet 3111, the air guiding cavity, and the third air outlet 372 in sequence and 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 dissipation member 38 and the mounting plate 31 of the box body. After heat exchange, the air flow enters the box body 20 through the first air outlet 3222. The air flow in the box body 20 is discharged to the outside through the top cover assembly 10 under the drive of the blades 13.

[0187] A wind hood member 37 is provided, and the third air outlet 372 on the wind hood member 37 is arranged between the second air outlet 3111 and the first air outlet 3222. Among them, the second air outlet 3111 is spaced above the third air outlet 372, and the first air outlet 3222 is spaced below the third air outlet 372. Thus, the air outlet position of the first air duct 3011 can form a bent structure, reducing the situation that rainwater and other foreign objects enter the installation space of the box body through the air outlet position of the first air duct 3011, reducing the adverse effects of rainwater and other foreign objects on the electronic control assembly, and effectively reducing the failure rate of the electronic control assembly.

[0188] It should be noted that the connection method between the wind hood member 37 and the mounting plate 31 includes but is not limited to riveting, welding, screw connection, or snap connection.

[0189] In some embodiments of the present invention, as Figure 17 shown, the second air inlet 3121 is arranged facing the surface of the third air outlet 372. A first air guiding plate body 361 inclined away from the mounting plate 31 is provided on the third side plate 36, and a second air guiding plate body 371 inclined towards the mounting plate 31 is provided on the wind hood member 37.

[0190] Specifically, in the vertical direction, the third air outlet 372 is located between the second air outlet 3111 and the first air outlet 3222. Among them, the second air outlet 3111 is spaced above the third air outlet 372, and the first air outlet 3222 is spaced below the third air outlet 372. At the same time, the second air inlet 3121 is arranged facing the surface of the third air outlet 372. Thus, the heat-exchanged air flows 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, reducing the situation that the heat-exchanged air flow escapes in the box body 20 and reducing the situation that the heat-exchanged air flow heats other components in the box body 20.

[0191] In addition, the second air guide plate body 371 is used to guide the air flow discharged from the third air outlet 372, so that the air flow through the third air outlet 372 flows toward the side close to the mounting plate 31 of the box body. When the air flow impacts on the mounting plate 31, it can fully mix with the air flow discharged from the first air outlet 3222, and then can be discharged into the interior of the box body 20 under the guidance of the first air guide plate body 361.

[0192] It should be noted that the first air guide plate body 361 is inclined away from the mounting plate 31. At this time, the guiding direction of the first air guide plate body 361 for the air flow is obliquely upward to 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 body 361, the air flow led into the interior of the box body 20 through the first air guide plate body 361 can flow toward the position of the blade 13, reducing the situation of air flow escaping in the box body 20, and effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0193] In some embodiments of the present invention, as Figures 16 to 22 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 perpendicularly 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 perpendicularly connected to the second vertical plate body 311. The first side plate 32 is connected to the bottom of the mounting plate 31, and the first vertical plate body 322 and the second vertical plate body 311 are coplanar, and the first horizontal plate body 321 and the second horizontal plate body 312 are coplanarly spliced.

[0194] The second side plate 33 is an arc-shaped plate. One arc-shaped side of the arc-shaped plate is connected to the first horizontal plate and the second horizontal plate, and the other arc-shaped side of the arc-shaped plate can be connected to the structure of the box body 20 to be closed. At this time, the other two straight sides of the arc-shaped plate are respectively connected to the mounting plate 31 of the box body. 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 enclose an installation space for the first air duct 3011. The third side plate 36 is an L-shaped cover structure. The third side plate 36, a part of the structure of the first vertical plate body 322, a part of the structure of the second vertical plate body 311 and a part of the structure of the second horizontal plate body 312 enclose the second air duct 3012. Among them, a first air inlet 3221 is opened on the first vertical plate body 322 of the first side plate 32, and a second air inlet 3121 is opened on the second horizontal plate body 312 of the mounting plate 31.

[0195] 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 communicated with the second air duct 3012. Driven by the blade 13, after the outside 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 3222, and the other part passes through the second air inlet 3121, the first air duct 3011, the second air outlet 3111, the air guiding cavity and the third air outlet 372. The structural forms 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.

[0196] It should be noted that, in the embodiments of the present invention, as Figure 16 and Figure 22 shown, wherein, the second air duct 3012 has an L-shaped structure, and the connection position of the second air inlet 3121 and the second air duct 3012 is close to the first air inlet 3221. When the air flow enters the second air duct 3012 through the first air inlet 3221, the air flow flows through two paths. One part continues to flow along the path of the second air duct 3012, and the other part enters the air duct through the second air inlet 3121 and flows along the path of the first air duct 3011.

[0197] In addition, the air flow rate entering the first air duct 3011 can be controlled by setting the connection position of the second air inlet 3121 and the second air duct 3012 to meet the heat dissipation requirements of different electronic control components.

[0198] In some embodiments of the present invention, as Figure 18 and Figure 20 shown, the first air inlet 3221 includes a plurality of first louver holes, and a first guiding portion is provided at a partial orifice position of the first louver holes. Among them, the first guiding portion is connected to the orifice on the side of the first louver hole close to the first horizontal plate body 321 of the first side plate 32, and an acute angle is formed between the first vertical plate body 322 and the first guiding portion.

[0199] Specifically, in the vertical direction, one end of the first air guiding portion is connected to the orifice above the first louver hole (the orifice on the side close to the first horizontal plate body 321), and the other end of the first air guiding portion is arranged at an acute angle with the first vertical plate body 322. The first air guiding portion can be located inside the second air duct 3012 or outside the second air duct 3012. In the drawings of the present invention, it is shown that the first air guiding portion is located outside the second air duct 3012. Specifically, at this time, the air inlet direction of the first air inlet area formed between the first air guiding portion and the first louver hole is obliquely upward, that is, the outside air flow enters the second air duct 3012 through the first louver hole under the guidance of the first air guiding structure from the lower oblique side of the first louver hole. The structure of the first louver hole is provided, so that the air can enter from the lower oblique side of the first air inlet 3221, thereby reducing the situation that rainwater and other foreign matters enter through the first air inlet 3221, and reducing the adverse effects of rainwater and other foreign matters on the outdoor unit 100 of the HVAC equipment.

[0200] It should be noted that, in the vertical direction, the cross section of the first louver hole is in a fan-shaped structure.

[0201] In addition, a plurality of 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-metal part (such as a plastic part), it can be processed by injection molding.

[0202] In addition, the included angle between the first vertical plate body 322 and the first air guiding portion can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°.

[0203] In some embodiments of the present invention, as Figure 18 shown, the second air inlet 3121 includes second louver holes. The number of the second louver holes is multiple. Second air guiding portions are arranged at partial orifice positions of the second louver holes. Among them, the second air guiding portion is connected to the orifice on the side of the second louver hole close to the first vertical plate body 322 of the mounting plate 31, and an acute angle is formed between the second horizontal plate body 312 of the mounting plate 31 and the second air guiding portion.

[0204] In the horizontal direction, one end of the second air guide portion is connected to the orifice of the second louver hole near the second vertical plate body 311, and the other end of the second air guide portion is arranged at an acute angle with the second horizontal plate body 312. The second air guide portion can be located inside the first air duct 3011 or outside the first air duct 3011 (i.e., inside the second air duct 3012). In the drawings of the present invention, it is shown that the second air guide portion is located inside the first air duct 3011. Specifically, when the air flow in the second air duct 3012 enters the first air duct 3011 through the second louver hole, under the guidance of the second air guide portion, the air flow flows in the direction away from the second vertical plate body 311 of the mounting plate 31. By providing the second air guide portion, the air flow in the second air duct 3012 can be effectively guided into the first air duct 3011, so that the air flow can be effectively distributed in the first air duct 3011 and the second air duct 3012, thereby effectively improving the heat dissipation effect on the electronic control component.

[0205] In addition, the second air inlet 3121 of the first air duct 3011 is communicated with the second air duct 3012, so as to reduce the situation that foreign matters such as rainwater enter the interior of the box body, and reduce the situation of the failure of the electronic control box assembly 30 caused by foreign matters such as rainwater entering the interior of the box body, thereby effectively improving the stable operation of the outdoor unit 100 of the heating and ventilation equipment.

[0206] It should be noted that in the vertical direction, the cross-section of the second louver hole is in a fan-shaped structure.

[0207] In addition, a plurality of second louver holes are arranged at intervals. When the mounting plate 31 is a metal part (such as a stainless steel part), the second louver holes can be processed by stamping. When the second side plate 33 is a non-metal part (such as a plastic part), it can be processed by injection molding.

[0208] In addition, the included angle between the second horizontal plate body 312 and the second air guide portion can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°.

[0209] In some embodiments of the present invention, as Figure 17 and Figure 20 shown, the second air outlet 3111 includes a plurality of third louver holes, and a third air guide portion is arranged at a partial orifice position of the third louver holes. Among them, the third air guide portion is used to guide the air flow discharged from the first air duct 3011 in the direction of the second air inlet 3121.

[0210] Specifically, in the vertical direction, one end of the third air guiding part is connected to the orifice (the orifice close to the first side plate 32) below the third louver hole, and the other end of the third air guiding part is arranged at an acute angle with the second vertical plate body 311 of the mounting plate 31. The third air guiding part can be located inside the first air duct 3011 or outside the second air duct 3012. In the drawings of the present invention, it is shown that the second air guiding part is located inside the first air duct 3011. Specifically, the air outlet direction of the third air inlet area formed between the third air guiding part and the third louver hole is obliquely downward, that is, the air flow in the first air duct 3011 is guided by the third air guiding part and discharged from the first air duct 3011 obliquely downward through the third louver hole. The structure of the third louver hole is arranged, so that the air outlet obliquely downward of the second air outlet 3111 can be realized, and further, the situation that foreign matters such as rainwater enter through the second air outlet 3111 can be reduced, and the adverse influence of foreign matters such as rainwater on the outdoor unit 100 of the HVAC equipment is reduced.

[0211] It should be noted that in the vertical direction, the cross section of the third louver hole is in a fan-shaped structure.

[0212] In addition, a plurality of third louver holes are arranged at intervals. When the mounting plate 31 is a metal part (such as a stainless steel part), the third louver holes can be processed by stamping. When the mounting plate 31 is a non-metal part (such as a plastic part), the third louver holes can be processed by injection molding.

[0213] In addition, the included angle between the second vertical plate body 311 of the mounting plate 31 and the third air guiding part can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°.

[0214] In some embodiments of the present invention, the second air inlet 3121 is arranged as a second louver hole, wherein the second louver hole has an opening area S1, 0 < S1 ≤ 12 mm 2 .

[0215] Specifically, when S1 > 12 mm 2 At this time, the opening area of the second air inlet 3121 is too large, and the blocking effect on mosquitoes is poor. In the embodiments of the present invention, by setting S1 to 0 < S1 ≤ 12 mm 2 , the second air inlet 3121 can block mosquitoes and the like, reduce the situation that mosquitoes enter the inside of the box body through the second air inlet 3121, thereby reducing the situation that the electric control components are damaged due to mosquitoes entering the inside of the box body, and further reducing the failure rate of the electric control box body components.

[0216] It should be noted that the orifice shape of the second louver hole can be a circular hole, a square hole or an oval hole, etc.

[0217] In addition, the value of the opening area S1 of the second louver hole can be 2 mm2 , 4 mm 2 , 6 mm 2 , 8 mm 2 , 10 mm 2 , 12 mm 2 。

[0218] In some embodiments of the present invention, the third air outlet 372 includes a hole portion, and the number of the hole portions is multiple. Among them, the opening area of each said hole portion is S2, and 0 < S2 ≤ 28.26 mm 2 。

[0219] Specifically, when S1 > 28.26 mm 2 , the opening area of the third air outlet 372 is too large, and the blocking effect on mosquitoes is poor. In the embodiments of the present invention, by setting S2 to 0 < S2 ≤ 28.26 mm 2 , the third air outlet 372 can block mosquitoes and the like, reducing the situation where mosquitoes enter the interior of the box body through the third air outlet 372, thereby reducing the situation where the electronic control components are damaged due to mosquitoes entering the interior of the box body, and further reducing the failure rate of the electronic control box body components.

[0220] It should be noted that the shape of the hole portion constituting the third air outlet 372 can be a circular hole, a square hole, an oval hole, or the like.

[0221] In addition, the value of the opening area S2 of the hole portion constituting the third air outlet 372 can be 2 m 2 , 4 mm 2 , 6 mm 2 , 8 mm 2 , 10 mm 2 , 12 mm 2 , 14 mm 2 , 16 mm 2 , 18 mm 2 , 20 mm 2 , 22 mm 2 , 24 mm 2 , 26 mm 2 , 28 mm 2 , 28.26 mm 2 。

[0222] In some embodiments of the present invention, as Figures 1 to 23 shown, such as Figure 2 , Figure 3 and Figure 23As shown, the box body 20 includes a bottom plate and side enclosing plates. Among them, the side enclosing plates and the heat exchanger 40 are respectively installed on the bottom plate, and the side enclosing plates are arranged circumferentially around the heat exchanger 40. A plurality of grille holes and notches are provided on the side enclosing plates. The grille holes are correspondingly arranged with the heat exchange positions of the heat exchanger 40 (such as heat exchange fins, etc.), and the open position of the heat exchanger 40 is correspondingly arranged with the notches. The electric control box assembly 30 is arranged at the position of the notch, and at least the side enclosing plates are connected to the electric control box assembly 30 (the bottom plate can also be connected to the electric control box assembly) to fix the electric control box assembly 30.

[0223] Specifically, the heat exchanger 40 is fixedly connected to the bottom plate, so as to use the bottom plate to support the heat exchanger 40, thereby reducing the shaking of the heat exchanger 40, and effectively reducing the faults of the heat exchanger 40. At the same time, grille holes are provided on the side enclosing plates. When the blade 13 rotates, the outside air flow can enter the box body 20 through the grille holes and exchange heat with the heat exchanger 40, so as to realize the heat exchange operation of the outdoor unit 100 of the heating and ventilation equipment. In addition, the electric control box assembly 30 is installed at the notch position, so as to structurally supplement the structure of the box body 20 and the open position of the heat exchanger 40, and further optimize the overall structural layout, effectively improving the space utilization rate of the overall structure of the outdoor unit 100 of the heating and ventilation equipment.

[0224] It should be noted that the connection and fixing methods between the heat exchanger 40 and the bottom plate include but are not limited to screw connection, riveting, welding, bonding or clamping. At the same time, the connection and fixing methods between the side enclosing plates and the bottom plate include but are not limited to screw connection, riveting, welding, bonding or clamping. In addition, the connection and fixing methods between the electric control box assembly 30 and the side enclosing plates include but are not limited to screw connection, riveting, welding, bonding or clamping.

[0225] In addition, the plurality of grille holes are dispersedly arranged on the side enclosing plates, so as to reduce the blockage of the air flow, thereby increasing the air flow entry volume, and further improving the heat exchange efficiency of the heat exchanger 40.

[0226] In some embodiments of the present invention, as Figure 23 shown, the outdoor unit 100 of the heating and ventilation equipment further includes a compressor assembly 50 installed in the box body 20. The heat exchanger 40 installed in the box body 20 is arranged circumferentially around the compressor assembly 50. Among them, the compressor assembly 50 includes an ejector-enhanced compressor 51, a valve group 52 with a four-way valve, a gas-liquid separator 53 and a plate heat exchanger 54. The ejector-enhanced compressor 51, the four-way valve, the gas-liquid separator 53 and the plate heat exchanger 54 are installed and fixed on the bottom plate. The four-way valve is respectively connected to the heat exchanger 40 and the ejector-enhanced compressor 51 through pipelines. The gas-liquid separator 53 is respectively connected to the four-way valve and the ejector-enhanced compressor 51 through pipelines. The plate heat exchanger 54 is respectively connected to the heat exchanger 40, the ejector-enhanced compressor 51 and the four-way valve through pipelines.

[0227] By setting the jet enthalpy-increasing compressor 51, simultaneously arranging corresponding jet enthalpy components in the pipeline, and combining with the use of the plate heat exchanger 54, the subcooling and superheat degrees of the refrigerant during operation are improved, and the energy efficiency of the outdoor unit 100 of the HVAC equipment is enhanced.

[0228] In some embodiments of the present invention, as Figure 23 shown, in the compressor assembly 50, there is also a bracket group having a plate heat exchanger bracket 55. Among them, the plate heat exchangers are fixedly arranged on the bottom plate, and the plate heat exchanger 54 is fixed on the plate heat exchanger bracket 55, so that the plate heat exchanger 54 can be in a vertical state, and further the plate heat exchanger 54 can fully exert its performance.

[0229] It should be noted that the connection and fixation methods between the plate heat exchanger bracket 55 and the bottom plate include but are not limited to screw connection, riveting, bonding, welding or clamping. Similarly, the connection and fixation methods between the plate heat exchanger 54 and the plate heat exchanger bracket 55 include but are not limited to screw connection, riveting, bonding, welding or clamping.

[0230] In addition, there are also multiple brackets in the bracket group. Among them, the jet enthalpy-increasing compressor 51, the gas-liquid separator 53, etc. can be respectively fixed on the bottom plate through the brackets, so that the compressor assembly 50 and the bottom plate can be arranged at intervals, and further the air flow can pass through the installation position of the compressor assembly 50, reducing the direct flow area of the air flow, improving the heat dissipation effect of the compressor assembly 50, and effectively reducing the failure rate of the outdoor unit 100 of the HVAC equipment.

[0231] In some embodiments of the present invention, as Figure 23 shown, the plate heat exchanger bracket 55 is arranged in an L-shaped structure. The bottom plate is connected and fixed to one side wall of the L-shaped structure, and the plate heat exchanger 54 is connected and fixed to the other side wall of the L-shaped structure. The structure of the plate heat exchanger bracket 55 is simple, which can effectively reduce the manufacturing cost.

By increasing the size of the blade 13, the driving ability of the blade 13 for the air flow is improved, thereby reducing the problem of the air flow stagnation area in the outdoor unit 100 of the HVAC equipment, effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment. At the same time, the inside of the box body 20 can communicate with the outside through the heat dissipation air duct 301 of the electric control box assembly 30. Driven by the blade 13, the air flow can enter the heat dissipation air duct 301 to realize the heat dissipation of the electric control box assembly 30, further reducing the problem of the air flow stagnation area in the outdoor unit 100 of the HVAC equipment.
