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

[0015] 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.

[0016] Furthermore, the first air guide also has a second air guide section, the first end of which is connected to the first air guide section, and the second end of which is adjacent to the heat dissipation fins to guide the airflow to the heat dissipation fins.

[0017] Furthermore, the inner diameter of the second air guide gradually increases from the first end to the second end.

[0018] Furthermore, the second air guide section and the first air guide section are integrally formed.

[0019] Furthermore, the first air guide and the middle partition together form an air intake channel, which is connected to the connecting port to guide the airflow to the heat dissipation fins.

[0020] Furthermore, the first air guide extends from the end opposite to the heat dissipation fins to the middle region of the partition plate, and the connection port is located in the middle region of the partition plate.

[0021] Furthermore, the first air guide extends from the end opposite to the heat dissipation fins to the bottom of the middle partition, and the connecting port is located in the bottom area of ​​the middle partition.

[0022] Furthermore, it also includes a second air guide, which is connected to the middle partition plate. The second air guide covers the top of the heat dissipation fins, or the second air guide abuts against the top of the heat dissipation fins, or there is a gap of less than or equal to 20 mm between the second air guide and the heat dissipation fins.

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.

[0036] 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.

[0037] 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.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0039] 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.

[0040] 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 that 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.

[0041] 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.

[0042] 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 an electrical control box and a first air guide component in a heating, ventilation, and air conditioning system provided in an embodiment of this application. FIG. 3 for FIG. 2 A magnified view of a section at point I; FIG. 4 An exploded view of an electrical control box and a first air guide component in a heating, ventilation, and air conditioning system provided in an embodiment of this application.

[0043] like FIG. 1 to FIG. 4 As shown in the embodiment of this application, a heating and ventilation device 100 includes a housing 110, an electrical control box 120, a partition 130, and a first air guide 140. The housing 110 has a hollow receiving cavity 111. The partition 130 is disposed in the receiving cavity 111 and divides the receiving cavity 111 into a first receiving cavity 111a and a second receiving cavity 111b. The first receiving cavity 111a and the second receiving cavity 111b are interconnected through a communication port 131. The first receiving cavity 111a is configured to form a negative pressure area relative to the second receiving cavity 111b, so that the airflow in the second receiving cavity 111b is drawn into the first receiving cavity 111a.

[0044] 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.

[0045] It is understood that it can be installed on the outdoor ground or on the outdoor wall, etc. The embodiments of the present invention are not limited in this way. In addition, it serves to support and accommodate other structures of the HVAC equipment 100.

[0046] For example, a partition 130 is vertically installed in the receiving cavity 111 to divide the receiving cavity 111 into a first receiving cavity 111a and a second receiving cavity 111b.

[0047] In some embodiments, the housing 110 is a regular three-dimensional structure, such as a cube, while the receiving cavity 111 can have a similar structure to a cube, thereby forming a thin-walled structure as a whole to improve its space utilization.

[0048] It should be noted that in this embodiment, the receiving cavity 111 can be a closed receiving cavity 111, which can be in a sealed state, that is, the receiving cavity 111 is a closed receiving cavity 111. With this configuration, when the HVAC equipment 100 is used in an outdoor environment, it can have waterproof, dustproof and corrosion-resistant properties in the face of harsh outdoor climate conditions. This allows other structures inside the receiving cavity 111, such as the electrical control box 120 in the HVAC equipment 100, to have a dry and clean working environment, so that 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.

[0049] Correspondingly, the partition 130 divides the receiving cavity 111 into a first receiving cavity 111a and a second receiving cavity 111b, wherein both the first receiving cavity 111a and the second receiving cavity 111b are sealed.

[0050] It should be noted that when the first receiving cavity 111a forms a negative pressure area relative to the second receiving cavity 111b, the airflow in the second receiving cavity 111b can be drawn into the first receiving cavity 111a for heat dissipation.

[0051] like FIG. 1 to FIG. 4 As shown, the electrical control box 120 and the first air guide 140 are both connected to the partition plate 130. The electrical control box 120 has heat dissipation fins 121 on the side facing the first receiving cavity 111a. The first air guide 140 covers the outside of the connecting port 131. At least part of the first air guide 140 is located on the lower side of the heat dissipation fins 121. The first air guide 140 is configured to guide the airflow drawn in by the second receiving cavity 111b to the heat dissipation fins 121.

[0052] For example, the electrical control box 120 can be fixed or detachably mounted on the partition plate 130, or it can be mounted on the partition plate 130 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.

[0053] Accordingly, the first air guide 140 can be fixed or detachably connected to the middle partition 130, or it can be connected to the middle partition 130 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 first air guide 140 is not limited here.

[0054] In some examples, the shape of the partition 130 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 130. This embodiment of the invention describes the partition 130 as a rectangular plate.

[0055] It should be noted that, in order to improve the heat dissipation effect, when the airflow from the second receiving cavity 111b flows to the first receiving cavity 111a, the airflow can be directed to the heat dissipation fins 121 for heat dissipation due to the setting of the first air guide 140, which is more conducive to heat dissipation.

[0056] With the above configuration, that is, by adding a first air guide 140, and the first air guide 140 covering the outside of the connecting port 131 and covering at least part of the heat dissipation fins 121, the airflow of the second receiving cavity 111b is guided by the first air guide 140 to flow into the heat dissipation fins 121 for heat dissipation, thereby improving the heat dissipation effect.

[0057] like FIG. 1 to FIG. 4As shown, in some alternative embodiments, the first air guide 140 has a first air guide portion 141 that covers the communication opening 131 to guide the airflow drawn in by the second receiving cavity 111b to the heat dissipation fins 121.

[0058] It is understandable that the first air guide 141 covers the outside of the connecting port 131, so that when the gas in the second receiving cavity 111b enters the first receiving cavity 111a through the connecting port 131, it flows into the heat dissipation fins 121 for heat dissipation under the guiding action of the first air guide 141.

[0059] For example, the connecting port 131 can be any shape, such as square, elliptical, trapezoidal, etc. This embodiment does not impose any specific restrictions on this.

[0060] In some alternative embodiments, the end of the first air guide 140 is flush with the end of at least a portion of the heat dissipation fins 121.

[0061] In some alternative implementations, the first air guide 140 is covered with at least a portion of the heat dissipation fins 121.

[0062] It is understandable that the arrangement of the first air guide 140 is not limited in this embodiment of the application, as long as it can play a guiding role.

[0063] In some examples, the first air guide 140 is covered at the upper or lower end of the heat dissipation fins 121. Specifically, it can be adjusted according to the actual situation. This application embodiment does not impose too many restrictions here.

[0064] In some examples, the first air guide 140 may be a metal component, and its material may include one or more of copper, iron, aluminum, tin, and lead. The casting mold may be made of sand, metal, or ceramic.

[0065] In other examples, the first air guide 140 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.

[0066] It should be noted that the specific material of the first air guide 140 is not subject to further restrictions in this embodiment of the invention.

[0067] Of course, during manufacturing, the first air guide 140 can also be made of steel plate, plastic or synthetic materials, provided that the strength is guaranteed.

[0068] For example, in order to reduce costs, the first air guide 140 are all stamped parts.

[0069] In some examples, the shape and size of the first air guide 140 can be adjusted according to the actual situation in this application embodiment, and this application embodiment will not impose too many restrictions here.

[0070] In some alternative embodiments, along the length of the heat dissipation fin 121, the first air guide 140 covers the heat dissipation fin 121 for a length of 1%-30% of the length of the heat dissipation fin 121.

[0071] Of course, it is not limited to the values ​​mentioned above.

[0072] In some alternative embodiments, there is a gap between the first air guide 141 and the heat dissipation fins 121, the gap being less than or equal to 20 mm.

[0073] 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 141 and the heat dissipation fins 121.

[0074] 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.

[0075] like FIG. 1 to FIG. 4 As shown, in some optional embodiments, the first air guide 141 has a flat plate structure, and the first air guide 141 extends from away from the heat dissipation fins 121 toward the heat dissipation fins 121.

[0076] Understandably, the flat plate structure design can reduce resistance during airflow. Furthermore, due to the structural design of the first air guide 141, when the gas in the second receiving cavity 111b enters the first receiving cavity 111a through the connecting port 131, it can flow to the heat dissipation fins 121 to a greater extent under the guiding effect of the first air guide 141.

[0077] like FIG. 1 to FIG. 4 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 141 toward the first air guide 141.

[0078] 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.

[0079] like FIG. 1 to FIG. 4As shown, in some optional embodiments, the first air guide 140 further has a second air guide portion 142, the first end of the second air guide portion 142 being connected to the first air guide portion 141, and the second end of the second air guide portion 142 being adjacent to the heat dissipation fins 121 to guide airflow to the heat dissipation fins 121.

[0080] It should be noted that the second air guide 142 and the first air guide 141 can be connected by a fixed or detachable connection, or by 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 between the second air guide 142 and the first air guide 141 is not limited here.

[0081] In addition, it should be noted that the first air guide 141 guides the airflow of the second receiving cavity 111b to the heat dissipation fins 121. Then, under the guidance of the second air guide 142, the airflow makes greater contact with the heat dissipation fins 121 to dissipate heat.

[0082] Continue to refer to FIG. 1 to FIG. 4 In some alternative embodiments, the second air guide 142 forms a cover that wraps around the outside of the heat dissipation fins 121. The first end of the cover is connected to the first air guide 141, the second end of the cover forms an opening, and the inner diameter of the cover gradually expands from the first end to the second end to accommodate the bottom end of the heat dissipation fins 121 inside the cover.

[0083] It is understood that the second air guide 142 is wrapped around the lower area of ​​the outer side of the heat dissipation fins 121, wherein the second air guide 142 has a first end and a second end that correspond to the first end and the second end of the cover, respectively.

[0084] The opening at the second end of the cover faces the middle region of the heat dissipation fins 121, and the first end of the cover is connected to the first air guide 141.

[0085] The second air guide 142 cooperates with the first air guide 141 to introduce the airflow of the second receiving cavity 111b into the first air guide 141 through the connecting port 131. The airflow is then introduced into the bottom area of ​​the heat dissipation fins 121 through the second air guide 142. After heat exchange, the gas exits from the opening at the second end of the cover, which is the middle area of ​​the heat dissipation fins 121.

[0086] Furthermore, it should be noted that the size and dimensions of the second air guide 142 and the first air guide 141 can be adjusted according to actual conditions, and this application embodiment does not impose too many restrictions here.

[0087] In some alternative embodiments, the second air guide 142 and the first air guide 141 are integrally formed.

[0088] In some embodiments, the second air guide 142 and the first air guide 141 are integrally formed, which can ensure that the second air guide 142 and the first air guide 141 are integrally formed and manufactured and are inseparable from each other.

[0089] 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 second air guide 142 and the first air guide 141, thereby improving assembly efficiency.

[0090] On the other hand, it can improve the overall rigidity of the first air guide 140, reduce the possibility of loosening between the second air guide 142 and the first air guide 141, and has high structural strength.

[0091] It should be noted that in some embodiments, the second air guide 142 and the first air guide 141 are connected in an integral connection manner.

[0092] In other embodiments, the second air guide 142 and the first air guide 141 may also be connected in other ways. As long as the connection method can fix the second air guide 142 and the first air guide 141, the purpose of this embodiment can be achieved. Here, the connection method of the second air guide 142 and the first air guide 141 is not limited.

[0093] In some alternative embodiments, the first air guide 140 and the middle partition 130 together form an air inlet channel, which is connected to the connecting port 131 and is opposite to the heat dissipation fins 121, so as to guide the airflow to the heat dissipation fins 121.

[0094] Understandably, the airflow in the second receiving cavity 111b flows through the connecting port 131 to the air inlet channel and flows out from the middle region of the heat dissipation fins 121.

[0095] In some examples, the partition 130 may be a metal component, and its material may include one or more of copper, iron, aluminum, tin, and lead.

[0096] In other examples, the partition 130 may also be made of plastic. It should be noted that the embodiments of the present invention do not impose excessive limitations on the specific material of the partition 130.

[0097] Of course, during manufacturing, the partition 130 can also be made of steel plate, plastic or synthetic materials, provided that the strength is guaranteed.

[0098] For example, in order to reduce costs, the partitions 130 are all stamped parts.

[0099] In some examples, the shape and size of the partition 130 can be adjusted according to the actual situation in this application embodiment, and this application embodiment will not impose too many restrictions here.

[0100] Continue to refer to FIG. 5 In some alternative embodiments, the first air guide 141 extends from one end away from the heat dissipation fins 121 to the middle region of the partition 130, and the communication port 131 is located in the middle region of the partition 130.

[0101] It is understood that the first air guide 141 is located in the middle region of the partition 130, and the connecting port 131 is also located in the middle region of the partition 130. The airflow of the second receiving cavity 111b flows in from the middle region of the partition 130 through the connecting port 131, and heat dissipation fins 121 are introduced into the first air guide 141 and the second air guide 142 for heat dissipation.

[0102] FIG. 6 This is a schematic diagram of the structure of a heating and ventilation device with another first air guide provided in an embodiment of this application. FIG. 7 This is an assembly diagram of another type of electrical control box and a first air guide component in the HVAC equipment provided in this application embodiment. FIG. 5 to FIG. 7 An exploded view of another electrical control box and a first air guide component in the HVAC equipment provided in the embodiments of this application.

[0103] like FIG. 1 to FIG. 7 As shown, in some alternative embodiments, the first air guide 141 extends from the end opposite to the heat dissipation fins 121 to the bottom of the partition 130, and the communication port 131 is located in the bottom region of the partition 130.

[0104] In some examples, a compressor housing 160 is also included, which is used to house the compressor and has a cable mounting hole 161 located in the central region of the partition 130.

[0105] It should be noted that when the compressor housing 160 is provided in the second receiving cavity 111b, the cable mounting hole 161 is located in the middle area of ​​the partition plate 130 in order to facilitate wiring. In order to avoid the cable mounting hole 161 and the connecting port 131 being too close to each other, which would cause noise and other problems, the position of the connecting port 131 can be set relatively far away from the cable mounting hole 161, so that there is a large distance between the connecting port 131 and the cable mounting hole 161.

[0106] Specifically, the end of the first air guide 141 can be extended to the bottom of the partition 130. In other words, the first air guide 141 can be made longer. At this time, the connecting port 131 is located in the bottom area of ​​the partition 130, which can avoid noise and other problems during the airflow.

[0107] like FIG. 4 As shown, in some alternative embodiments, the first receiving cavity 111a is provided with a fan 170, which is configured to drive airflow to create a negative pressure area in the first receiving cavity 111a.

[0108] It should be noted that when the fan 170 is running, the first receiving cavity 111a forms a negative pressure area.

[0109] Specifically, you can refer to FIG. 7 as well as FIG. 1 to FIG. 7 In the direction of the middle arrow, when the fan 170 in this application is configured to rotate counterclockwise, the gas in the second receiving cavity 111b enters the first air guide section 141 and the second air guide section 142 through the connecting port 131 at the bottom of the partition plate 130 or the connecting port 131 in the middle of the partition plate 130, and finally enters the heat dissipation fins 121 for heat dissipation.

[0110] like ​ As shown, in some optional embodiments, a second air guide 150 is also included. The second air guide 150 is connected to the middle partition 130. The second air guide 150 covers the top of the heat dissipation fin 121, or the second air guide 150 abuts against the top of the heat dissipation fin 121, or there is a gap of less than or equal to 20 mm between the second air guide 150 and the heat dissipation fin 121.

[0111] Understandably, the second air guide 150 is located at the top of the heat dissipation fin 121 to guide the gas at the top of the heat dissipation fin 121 to flow to the heat dissipation fin 121 for heat dissipation.

[0112] In addition, the second air guide 150 can be configured with reference to the first air guide 140. The specific details will not be elaborated further in the embodiments of this application.

[0113] The HVAC equipment provided by the present invention includes a housing, an electrical control box, a partition plate, and a first air guide. The housing has a hollow receiving cavity, and the partition plate is disposed in the receiving cavity and divides the receiving cavity into a first receiving cavity and a second receiving cavity. The first receiving cavity and the second receiving cavity are interconnected through a connecting port, and the first receiving cavity is configured to form a negative pressure area relative to the second receiving cavity so that the airflow in the second receiving cavity is drawn into the first receiving cavity. The electrical control box and the first air guide are both connected to the partition plate. The side of the electrical control box facing the first receiving cavity is provided with heat dissipation fins. The first air guide covers the outside of the connecting port and is located below the heat dissipation fins. The first air guide is configured to guide the airflow drawn in from the second receiving cavity to the heat dissipation fins.

[0114] By adding a first air guide that covers the outside of the connecting opening and is covered with at least part of the heat dissipation fins, the airflow in the second receiving cavity is guided by the first air guide to flow into the heat dissipation fins for heat dissipation, thereby improving the heat dissipation effect.
