Description

TECHNICAL FIELD

[0001] The present application relates to the field of heating and ventilation technology, and particularly relates to a heating and ventilation device. BACKGROUND

[0002] In a heating and ventilation system, an electric control box is generally needed to control the related work of each component. When the heating and ventilation device is working, the electric control box is used to control the operation of components such as compressors in the heating and ventilation device. When the electric control box works for a long time, the circuit board assembly in the electric control box will release a large amount of heat during operation. If the heat cannot be dissipated in time, the circuit board assembly will be burned or damaged, thereby reducing the service life of the circuit board assembly. Therefore, heat dissipation is the primary consideration in the design of the electric control box.

[0003] In the related art, a radiator is installed on the electric control box to dissipate heat from the components, but the airflow of the heating and ventilation device flows through the radiator less, resulting in poor heat dissipation effect of the components, which cannot solve the technical problem that the components malfunction due to high temperature, thereby affecting the performance of the whole machine. SUMMARY

[0004] The main purpose of the present application is to provide a heating and ventilation device with good heat dissipation effect.

[0005] To achieve the above-mentioned purpose, the present application provides a heating and ventilation device, which comprises a shell assembly and an electric control box. The shell assembly comprises a shell, a partition plate and an air guide unit. The shell has a hollow accommodating cavity. The partition plate is arranged in the accommodating cavity and divides the accommodating cavity into a first accommodating cavity and a second accommodating cavity which are in communication with each other. The first accommodating cavity and the second accommodating cavity are in communication with each other through a communication port. The first accommodating cavity is configured to form a negative pressure area relative to the second accommodating cavity, so that the airflow in the second accommodating cavity is sucked into the first accommodating cavity.

[0006] The air guide unit and the electric control box are arranged on the partition plate. The side of the electric control box facing the first accommodating cavity is provided with a heat dissipation fin. The air guide unit forms an air guide channel. The air guide channel is located above the heat dissipation fin and has an opening facing the heat dissipation fin. The air guide channel is configured to guide the airflow sucked from the second accommodating cavity to the heat dissipation fin.

[0007] The present application has the following advantages. By increasing the air guide unit, and the air guide channel of the air guide unit extending along the partition plate, and the opening of the air guide channel wrapping at least part of the heat dissipation fin, the airflow in the second accommodating cavity is guided by the air guide unit to flow into the heat dissipation fin for heat dissipation, thereby improving the heat dissipation effect.

[0008] On the basis of the above technical solution, the present application can be further improved as follows.

[0009] Further, at least part of the channel segments of the air guide channel and the extension direction of the heat dissipation fin are parallel to each other.

[0010] Furthermore, the shape of the opening matches the contour of the heat dissipation fins.

[0011] Furthermore, the air guiding unit includes a first air guiding component, which is used to form at least a portion of the air guiding channel. The first air guiding component includes a first air guiding section, which has a gap with the middle partition. One end of the first air guiding section is disposed opposite to the communication port, and the other end extends to the heat dissipation fins.

[0012] Furthermore, there are multiple heat dissipation fins, and adjacent heat dissipation fins are spaced apart to form heat dissipation grooves, which extend from away from the first air guide section to closer to the first air guide section.

[0013] Furthermore, the end of the first air guide is flush with the end of at least a portion of the heat dissipation fins.

[0014] Furthermore, the first air guide is covered with at least some heat dissipation fins.

[0015] Furthermore, along the length of the heat dissipation fins, the length of the first air guide covering the heat dissipation fins is 1%-30% of the length of the heat dissipation fins.

[0016] Furthermore, there is a gap between the first air guide section and the heat dissipation fins, and the gap is less than or equal to 20mm.

[0017] Furthermore, the first air guide also includes two support parts connected to opposite sides of the first air guide section. The ends of the two support parts facing away from the first air guide section are connected to the middle partition, so that the first air guide and the middle partition together form a channel section of the air guide channel.

[0018] Furthermore, the air guiding unit also includes a second air guiding component, which is connected to the end of the first air guiding component away from the heat dissipation fins. The second air guiding component has at least one second air guiding section, with the first end of the second air guiding section extending to the communication port and the second end extending toward the first air guiding component. The extending directions of the second air guiding section and the first air guiding section have an angle.

[0019] Furthermore, the second air guide has two second air guide sections, which are respectively disposed on the upper and lower sides of the connecting opening. The second air guide section disposed on the upper side of the connecting opening extends to the first air guide section, and the second air guide section disposed on the lower side of the connecting opening is spaced apart from the first air guide section.

[0020] Furthermore, the first air guide component, the second air guide component, the support section, and the middle partition plate together form an air guide channel.

[0021] The HVAC equipment provided by the present invention includes a housing assembly and an electrical control box. The housing assembly includes a housing, a partition, and an air guide unit. The housing has a hollow receiving cavity. The partition is disposed in the receiving cavity and divides the receiving cavity into a first receiving cavity and a second receiving cavity that are interconnected. The first receiving cavity and the second receiving cavity are interconnected through a communication port. The first receiving cavity is configured to form a negative pressure area relative to the second receiving cavity so that airflow in the second receiving cavity is drawn into the first receiving cavity. The air guide unit and the electrical control box are disposed on the partition. The side of the electrical control box facing the first receiving cavity has heat dissipation fins. The air guide unit forms an air guide channel. The air guide channel is located on the upper side of the heat dissipation fins and has an opening facing the heat dissipation fins. The air guide channel is configured to guide the airflow drawn in from the second receiving cavity to the heat dissipation fins.

[0022] By adding an air guide unit, and the air guide unit having an air guide channel extending along the middle partition, the opening of the air guide channel wraps at least part of the heat dissipation fins, so that the airflow in the second receiving cavity flows into the heat dissipation fins under the guidance of the air guide unit for heat dissipation, thereby improving the heat dissipation effect.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features can be combined with each other.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0038] In HVAC systems, electrical control boxes are commonly required to control the operation of various components. During operation, these boxes control the operation of components such as compressors. When the control box operates for extended periods, the circuit board assemblies within it release a significant amount of heat. If this heat cannot be dissipated promptly, it will inevitably burn out or damage the circuit board assemblies, thus reducing their lifespan. Therefore, heat dissipation is a primary consideration in control box design. While some technologies involve installing radiators on the control box to cool the components, the airflow through these radiators is limited, resulting in poor heat dissipation and failing to address the issue of component malfunctions due to overheating. This ultimately affects the overall performance of the system.

[0039] To overcome the deficiencies in the prior art, the HVAC equipment provided by the present invention improves the heat dissipation effect by adding a first air guide component, which covers the outside of the communication opening and is covered with at least part of the heat dissipation fins, so that the airflow in the second receiving cavity flows into the heat dissipation fins under the guidance of the first air guide component.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] FIG. 1 This is a schematic diagram of the structure of the HVAC equipment provided in the embodiments of this application. FIG. 2 This is an assembly drawing of the electrical control box and the first air guide component in the HVAC equipment provided in the embodiments of this application. FIG. 3 for FIG. 2 A magnified view of a section at point I. FIG. 4 This is an assembly drawing of some air guide units and middle partitions in the HVAC equipment provided in the embodiments of this application. FIG. 5This is an assembly diagram of the air guide unit and the partition plate in the HVAC equipment provided in the embodiments of this application.

[0042] like FIG. 1 to FIG. 5 As shown in the figure, an HVAC device 100 provided in this application embodiment includes a housing assembly 110 and an electrical control box 120. The housing assembly 110 includes a housing 111, a partition 112 and an air guide unit. The housing 111 has a hollow receiving cavity 1111. The partition 112 is disposed in the receiving cavity 1111 and divides the receiving cavity 1111 into a first receiving cavity 1111a and a second receiving cavity 1111b that are interconnected. The first receiving cavity 1111a and the second receiving cavity 1111b are interconnected through a communication port 1121. The first receiving cavity 1111a is configured to form a negative pressure area relative to the second receiving cavity 1111b, so that the airflow in the second receiving cavity 1111b is drawn into the first receiving cavity 1111a.

[0043] It should be noted that the HVAC equipment 100 provided in this application embodiment can be an air conditioner, a multi-split system, a heat pump, a pool machine, etc. Specifically, this application embodiment does not impose too many restrictions here.

[0044] It is understood that the housing assembly 110 can be installed on the outdoor ground or on an outdoor wall, etc. The embodiments of the present invention will not be limited in this way. In addition, the housing assembly 110 serves to support and accommodate other structures of the HVAC equipment 100.

[0045] For example, a partition 112 is vertically installed in the receiving cavity 1111 to divide the receiving cavity 1111 into a first receiving cavity 1111a and a second receiving cavity 1111b.

[0046] In some embodiments, the housing 111 is a regular three-dimensional structure, such as a cube, and the receiving cavity 1111 can have a similar structure to the cube, thereby making the housing assembly 110 as a whole a thin-walled structure to improve its space utilization.

[0047] It should be noted that in this embodiment, the receiving cavity 1111 can be a closed receiving cavity 1111, and the housing assembly 110 can be in a sealed state, that is, the receiving cavity 1111 is a closed receiving cavity 1111. With this configuration, when the HVAC equipment 100 is used in an outdoor environment, facing the harsh outdoor climate, the housing assembly 110 can have waterproof, dustproof, and corrosion-resistant properties, so that other structures in the receiving cavity 1111, such as the electrical control box 120 in the HVAC equipment 100, have a dry and clean working environment, thereby the electrical control box 120 can work normally, improving the reliability of the electrical control box 120 and extending the service life of the HVAC equipment 100.

[0048] Correspondingly, the partition 112 divides the receiving cavity 1111 into a first receiving cavity 1111a and a second receiving cavity 1111b, wherein both the first receiving cavity 1111a and the second receiving cavity 1111b are sealed.

[0049] It should be noted that when the first receiving cavity 1111a forms a negative pressure area relative to the second receiving cavity 1111b, the airflow in the second receiving cavity 1111b can be drawn into the first receiving cavity 1111a for heat dissipation.

[0050] The air guide unit and the electrical control box 120 are disposed on the partition plate 112. The electrical control box 120 has heat dissipation fins 121 on the side facing the first receiving cavity 1111a. The air guide unit forms an air guide channel, which is located on the upper side of the heat dissipation fins 121. At least a portion of the air guide channel extends along the partition plate 112. The air guide channel has an opening facing the heat dissipation fins 121. The air guide channel is configured to guide the airflow drawn in by the second receiving cavity 1111b to the heat dissipation fins 121.

[0051] For example, the electrical control box 120 can be mounted on the partition plate 112 using a fixed or detachable connection method, or it can be mounted on the partition plate 112 using other connection methods, such as threaded connection or snap-fit ​​connection. As long as the purpose of this embodiment can be achieved, the connection method of the electrical control box 120 is not limited here.

[0052] Accordingly, the air guide unit can be fixed or detachably mounted on the partition plate 112, or it can be mounted on the partition plate 112 using other connection methods, such as threaded connection or snap-fit ​​connection. As long as the purpose of this embodiment can be achieved, the connection method of the air guide unit is not limited here.

[0053] In some examples, the shape of the partition 112 can be a rectangular plate, a trapezoidal plate, or a rectangular frame. This embodiment of the invention does not specifically limit the shape of the partition 112. This embodiment of the invention describes the partition 112 as a rectangular plate.

[0054] It should be noted that, in order to improve the heat dissipation effect, when the airflow from the second receiving cavity 1111b flows to the first receiving cavity 1111a, the airflow can be directed to the heat dissipation fins 121 for heat dissipation due to the setting of the air guide unit, which is more conducive to heat dissipation.

[0055] Specifically, the airflow guiding unit is located on the upper side of the heat dissipation fins 121, as can be seen in the following reference. FIG. 4 The airflow in the second receiving cavity 1111b flows into the air guide channel through the upper connecting port 1121. Under the guidance of the air guide channel, the airflow is directed to the heat dissipation fins 121 for heat dissipation.

[0056] In addition, the opening design of the air duct makes it easier to wrap the heat dissipation fins 121 on the upper side, thereby improving heat dissipation.

[0057] With the above configuration, namely, by adding an air guide unit, and the air guide unit having an air guide channel extending along the middle partition 112, the opening of the air guide channel covering at least part of the heat dissipation fins 121, so that the airflow of the second receiving cavity 1111b flows into the heat dissipation fins 121 for heat dissipation under the guidance of the air guide unit, thereby improving the heat dissipation effect.

[0058] like FIG. 1 to FIG. 8 As shown, in some alternative embodiments, at least a portion of the air duct and the extending direction of the heat dissipation fins 121 are parallel to each other.

[0059] It should be noted that this design facilitates the airflow of the second receiving cavity 1111b into the heat dissipation fins 121 for heat dissipation. In addition, the overall structure is compact.

[0060] In some alternative implementations, the shape of the opening matches the profile of the heat dissipation fins 121.

[0061] Understandably, this design allows for greater airflow into the heat dissipation fins 121 for heat dissipation.

[0062] It should be noted that the specific shape of the opening can be adjusted according to the actual situation, and the embodiments of this application will not impose too many restrictions here.

[0063] In some alternative embodiments, the air guiding unit includes a first air guiding member 113, which is used to form at least a portion of the air guiding channel. The first air guiding member 113 includes a first air guiding section 1131, which has a gap with the middle partition 112. One end of the first air guiding section 1131 is disposed opposite to the connecting port 1121, and the other end extends to the heat dissipation fins 121.

[0064] It is understood that the first air guide 1131 extends from the end opposite to the connecting port 1121 to the end opposite to the heat dissipation fins 121. When the airflow of the second receiving cavity 1111b enters the air guide channel through the connecting port 1121, the airflow flows into the heat dissipation fins 121 and dissipates heat under the guiding action of the first air guide 1131.

[0065] For example, the connecting port 1121 can be in any shape, such as square, ellipse, trapezoid, etc. This embodiment does not impose any specific restrictions on this.

[0066] Furthermore, it should be noted that the first air guide section 1131 and the middle partition plate 112 are spaced apart to better wrap the heat dissipation fins 121. The distance between the first air guide section 1131 and the middle partition plate 112 can be adjusted according to the size of the heat dissipation fins 121. This embodiment of the application does not impose too many limitations here.

[0067] like FIG. 1 to FIG. 8 As shown, in some optional embodiments, there are multiple heat dissipation fins 121, and adjacent heat dissipation fins 121 are spaced apart to form heat dissipation grooves 122, which extend from away from the first air guide portion 1131 toward the first air guide portion 1131.

[0068] Understandably, in order to improve the heat dissipation effect of the entire HVAC system 100, there are multiple heat dissipation fins 121, and there are heat dissipation grooves 122 between two adjacent heat dissipation fins 121 to increase the contact area between the gas and the heat dissipation fins 121, thereby improving the heat dissipation effect.

[0069] In some alternative embodiments, the end of the first air guide 113 is flush with the end of at least a portion of the heat dissipation fins 121.

[0070] In some alternative implementations, the first air guide 113 is covered with at least a portion of the heat dissipation fins 121.

[0071] It is understandable that the arrangement of the first air guide 113 is not limited in this embodiment of the application, as long as it can play an air guiding role.

[0072] In some alternative embodiments, along the length of the heat dissipation fin 121, the first air guide 113 covers the heat dissipation fin 121 for a length of 1%-30% of the length of the heat dissipation fin 121.

[0073] Of course, it is not limited to the values ​​mentioned above.

[0074] In some alternative embodiments, there is a gap between the first air guide 1131 and the heat dissipation fins 121, the gap being less than or equal to 20 mm.

[0075] It is understandable that the gap allows gas to flow out from the heat dissipation fins 121. In addition, considering the manufacturing error, there will be a certain gap between the first air guide 1131 and the heat dissipation fins 121.

[0076] For example, the gap can be 5mm, 10mm, 15mm or 20mm, or other values. The specific values ​​are not limited in this embodiment of the application.

[0077] FIG. 6 This is an exploded view of the air guiding unit in the HVAC equipment provided in the embodiments of this application.FIG. 7 This is a schematic diagram of the structure of the first air guide component in the HVAC equipment provided in the embodiments of this application. FIG. 8 This is a schematic diagram of the structure of the second air guide component in the HVAC equipment provided in the embodiments of this application.

[0078] like FIG. 1 to FIG. 8 As shown, in some optional embodiments, the first air guide 113 further includes two support portions 1132 respectively connected to opposite sides of the first air guide portion 1131. The ends of the two support portions 1132 facing away from the first air guide portion 1131 are disposed on the middle partition 112, so that the first air guide 113 and the middle partition 112 together form a channel section of the air guide channel.

[0079] Understandably, the arrangement of the two support parts 1132 and the first air guide part 1131 can better form a partial air guide channel, in other words, they work together to guide the air. In addition, the two support parts 1132 can also connect the middle partition 112 to improve the installation strength of the entire first air guide component 113.

[0080] In some examples, the support portion 1132 may be fixedly or detachably connected to the partition plate 112, or it may be connected to the partition plate 112 in other ways, such as threaded connection or snap-fit ​​connection. As long as the purpose of this embodiment can be achieved, the connection method of the support portion 1132 is not limited here.

[0081] In some embodiments, the support portion 1132 and the first air guide portion 1131 are integrally formed, which can ensure that the support portion 1132 and the first air guide portion 1131 are integrally formed and manufactured and are inseparable from each other.

[0082] On the one hand, it can reduce the number of parts used, reduce the assembly difficulty and assembly accuracy requirements, and eliminate the welding connection process between the support part 1132 and the first air guide part 1131, thereby improving assembly efficiency.

[0083] On the other hand, it can improve the overall rigidity of the first air guide 113, reduce the possibility of loosening between the support part 1132 and the first air guide 1131, and has a high structural strength.

[0084] It should be noted that in some embodiments, the support part 1132 and the first air guide part 1131 are connected by an integral connection.

[0085] In other embodiments, the support portion 1132 and the first air guide portion 1131 may also be connected in other ways. As long as the connection method can fix the support portion 1132 and the first air guide portion 1131, the purpose of this embodiment can be achieved. Here, the connection method of the support portion 1132 and the first air guide portion 1131 is not limited.

[0086] like FIG. 1 to FIG. 8 As shown, in some optional embodiments, the air guiding unit further includes a second air guiding member 114, which is connected to the end of the first air guiding member 113 away from the heat dissipation fins 121. The second air guiding member 114 has at least one second air guiding section 1141, the first end of which extends to the communication port 1121, and the second end extends toward the first air guiding member 113. The extending directions of the second air guiding section 1141 and the first air guiding section 1131 have an angle.

[0087] Understandably, the design of the second air guide 114 facilitates the guidance of the airflow from the connecting port 1121 to the channel section of the air guide channel formed by the first air guide 113.

[0088] It should be noted that the extension directions of the second air guide 1141 and the first air guide 1131 are perpendicular to each other, and may also have other angles. Specifically, the embodiments of this application will not be limited in detail here.

[0089] It should be noted that the first air guide 113 and the second air guide 114 can be metal parts, and their materials can include one or more of copper, iron, aluminum, tin, and lead. The material of the casting mold can be sand, metal, or ceramic.

[0090] In other examples, the first air guide 113 and the second air guide 114 may also be made of plastic. During injection molding, molten plastic is injected into a plastic product mold under pressure, and then cooled and solidified to obtain the desired plastic part.

[0091] It should be noted that the specific materials of the first air guide 113 and the second air guide 114 are not subject to excessive restrictions in this embodiment of the invention.

[0092] Of course, during manufacturing, provided that the strength is guaranteed, the first air guide 113 and the second air guide 114 can also be made of steel plate, plastic or synthetic materials.

[0093] For example, in order to reduce costs, both the first air guide 113 and the second air guide 114 are stamped parts.

[0094] In some examples, the shape and size of the first air guide 113 and the second air guide 114 can be adjusted according to the actual situation in this application embodiment, and this application embodiment will not impose too many restrictions here.

[0095] like FIG. 1 to FIG. 8As shown, in some optional embodiments, the second air guide 114 has two second air guide sections 1141, which are respectively disposed on the upper and lower sides of the connecting port 1121. The second air guide section 1141 disposed on the upper side of the connecting port 1121 extends to the first air guide section 1131, and the second air guide section 1141 disposed on the lower side of the connecting port 1121 and the first air guide section 1131 are spaced apart.

[0096] It is understandable that the second air guide 1141 located on the upper side of the connecting port 1121 is connected to the first air guide 1131, and there is a certain gap between the second air guide 1141 located on the lower side of the connecting port 1121 and the first air guide 1131. The design of the gap facilitates the flow of air from the connecting port 1121 to the heat dissipation fins 121 through the gap.

[0097] like FIG. 1 to FIG. 8 As shown, in some optional embodiments, the first air guide 113, the second air guide 114, the support 1132 and the middle partition 112 together form an air guide channel.

[0098] It is understandable that the first air guide 113 and the second air guide 114 form an air guide channel to facilitate the airflow of the second receiving cavity 1111b into the heat dissipation fins 121 for heat dissipation.

[0099] like FIG. 1 to FIG. 8 As shown, in some optional embodiments, the second air guide 114 further includes a connecting portion 1142, which is connected to the middle partition 112.

[0100] Understandably, the connecting part 1142 serves to connect the middle partition 112 in order to improve the installation strength of the entire second air guide 114.

[0101] In some examples, the connecting part 1142 may be fixed or detachable on the partition plate 112, or it may be connected in other ways, such as threaded connection or snap-fit ​​connection. As long as the purpose of this embodiment can be achieved, the connection method of the connecting part 1142 is not limited here.

[0102] In some embodiments, the connecting portion 1142 and the second air guide portion 1141 are integrally formed, which can ensure that the connecting portion 1142 and the second air guide portion 1141 are integrally formed and manufactured and are inseparable from each other, thereby improving assembly efficiency and having high structural strength.

[0103] In some alternative embodiments, both the first air guide 1131 and the support 1132 are plate-shaped members, so that the first air guide 113 constitutes an air guide shroud.

[0104] Understandably, the design of the plate-like structure can reduce resistance during airflow. Furthermore, due to the structural design of the first air guide 1131, when the gas in the second receiving cavity 1111b enters the first receiving cavity 1111a through the connecting port 1121, it can flow to the heat dissipation fins 121 to a greater extent under the guiding action of the first air guide 1131.

[0105] In some alternative embodiments, the first air guide 113 and the second air guide 114 are integrally formed structures.

[0106] In some embodiments, the first air guide 113 and the second air guide 114 are integrally formed, which can ensure that the first air guide 113 and the second air guide 114 are integrally formed and manufactured and are inseparable from each other.

[0107] On the one hand, it can reduce the number of parts used, reduce the assembly difficulty and assembly accuracy requirements, and eliminate the welding connection process of the first air guide 113 and the second air guide 114, thereby improving assembly efficiency.

[0108] On the other hand, it can improve the overall rigidity of the air guide unit, reduce the possibility of loosening between the first air guide 113 and the second air guide 114, and has higher structural strength.

[0109] It should be noted that in some embodiments, the first air guide 113 and the second air guide 114 are connected in an integral connection manner.

[0110] In other embodiments, the first air guide 113 and the second air guide 114 can also be connected in other ways. As long as the connection method can fix the first air guide 113 and the second air guide 114, the purpose of this embodiment can be achieved. Here, the connection method of the first air guide 113 and the second air guide 114 is not limited.

[0111] like FIG. 1 to FIG. 8 As shown, in some alternative embodiments, the first receiving cavity 1111a is provided with a fan 130, which is configured to drive airflow to create a negative pressure area in the first receiving cavity 1111a.

[0112] It should be noted that when the fan 130 is running, the first receiving cavity 1111a forms a negative pressure area.

[0113] Specifically, when the fan 130 in this application is configured to rotate clockwise, the gas in the second receiving cavity 1111b enters the second air guide section 1141 through the connecting port 1121 at the upper end of the partition plate 112, and finally enters the heat dissipation fins 121 for heat dissipation.

[0114] like​ As shown, in some alternative embodiments, the first air guide 1131 covers a portion of the heat dissipation fin 121 at one end facing the heat dissipation fin 121.

[0115] In some examples, the first air guide 1131 is covered on the upper end of the heat dissipation fins 121. The specific covering area can be adjusted according to the actual situation, and this application embodiment will not impose too many restrictions here.

[0116] The HVAC equipment provided by the present invention includes a housing assembly and an electrical control box. The housing assembly includes a housing, a partition, and an air guide unit. The housing has a hollow receiving cavity. The partition is disposed in the receiving cavity and divides the receiving cavity into a first receiving cavity and a second receiving cavity that are interconnected. The first receiving cavity and the second receiving cavity are interconnected through a communication port. The first receiving cavity is configured to form a negative pressure area relative to the second receiving cavity so that airflow in the second receiving cavity is drawn into the first receiving cavity. The air guide unit and the electrical control box are disposed on the partition. The side of the electrical control box facing the first receiving cavity has heat dissipation fins. The air guide unit forms an air guide channel. The air guide channel is located on the upper side of the heat dissipation fins and has an opening facing the heat dissipation fins. The air guide channel is configured to guide the airflow drawn in from the second receiving cavity to the heat dissipation fins.

[0117] By adding an air guide unit, and the air guide unit having an air guide channel extending along the middle partition, the opening of the air guide channel wraps at least part of the heat dissipation fins, so that the airflow in the second receiving cavity flows into the heat dissipation fins under the guidance of the air guide unit for heat dissipation, thereby improving the heat dissipation effect.
