[0056] ​​​At present, the existing technology usually has an electric control box inside the heating and ventilation equipment, and the control circuit board carrying electronic components is arranged in the electric control box, so as to control the heating and ventilation equipment through the control circuit board. When the heating and ventilation equipment is running, some electronic components on the control circuit board will generate a large amount of heat, which will affect the normal operation of the electronic components, so that the heat management efficiency of the electric control box in the heating and ventilation equipment is low, and the heat dissipation performance of the control circuit board is poor.

[0057] In order to improve the heat management efficiency of the electric control box in the prior art, the electric control box in the related art is arranged as an open structure, and a specific heat dissipation structure is arranged inside or outside the electric control box, for example, a heat dissipation fan is arranged in the electric control box. However, the electric control box has many electrical components, and the addition of the heat dissipation component increases the occupied space of the electric control box and its related accessories in the heating and ventilation equipment, which not only has low space utilization, but also has insufficient heat dissipation efficiency.

[0058] Therefore, the present application provides a heating and ventilation equipment, which improves the heat management efficiency of the electric control box by improving the structure of the shell of the electric control box in the heating and ventilation equipment, and divides the electric control box into multiple independent electric control boxes arranged at different positions in the heating and ventilation equipment. The high-heat circuit components can be efficiently cooled, and the low-heat circuit components do not use separate cooling means, thereby improving the heat management efficiency of the electric control box and solving the technical problem of low heat management efficiency of the existing electric control box.

[0059] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0060] In order to facilitate understanding, first, the application scenario of the electric control box and the heating and ventilation equipment provided by the embodiments of the present application will be described.

[0061] In the heating and ventilation equipment provided by the embodiments of the present application, the electric control box is used to control the operation of the heating and ventilation equipment. The heating and ventilation equipment can be applied to occasions for adjusting temperature, for example, adjusting the water temperature of a swimming pool to maintain the pool water in the swimming pool in a relatively constant temperature. The pool water in the swimming pool can be circulated into the heating and ventilation equipment for heat exchange. In addition, the heating and ventilation equipment can be used in fields requiring water temperature control, such as aquaculture, and can be used for adjusting air temperature to realize the functions of heating or cooling.

[0063] Referring to FIG. 1 to FIG. 8 The heating and ventilation device of the present application includes a device main body 200, a first electric control box 100 and a second electric control box 300. The device main body 200 can include a cabinet 210 and a first partition plate 220 arranged in the cabinet 210. The first partition plate 220 divides the interior of the cabinet 210 into a fan cavity 211 and a compressor cavity 212. The first electric control box 100 is arranged on the first partition plate 220, so that the first electric control box 100 is located at the division between the fan cavity 211 and the compressor cavity 212, to realize the installation of the second electric control box 300 in the cabinet 210. The second electric control box 300 is arranged in the compressor cavity 212. The first electric control box 100 and the second electric control box 300 can be independently installed, and the first electric control box 100 and the second electric control box 300 cooperate to realize the control function of the heating and ventilation device.

[0064] The first electric control box 100 includes a first shell 110 and a first circuit assembly 120, and the first circuit assembly 120 is arranged in the first shell 110. The second electric control box 300 includes a second shell 310 and a second circuit assembly 320, and the second circuit assembly 320 is arranged in the second shell 310. When the heating and ventilation device is working, the heat generation of the second circuit assembly 320 is lower than that of the first circuit assembly 120. Therefore, the heat dissipation requirement of the first circuit assembly 120 is greater than that of the second circuit assembly 320.

[0065] It can be understood that the first shell 110 is at least partially located in the fan cavity 211, and the first electric control box 100 is configured to be cooled by the airflow in the fan cavity 211, so that the first circuit assembly 120 with high heat dissipation requirement can transfer heat to the first shell 110 and dissipate heat by the airflow in the fan cavity 211, and the second shell 310 located in the compressor cavity 212 can be set at the edge gap position in the compressor cavity 212 according to the space utilization of the compressor cavity 212, and dissipate heat naturally, thereby fully utilizing the space.

[0066] It should be noted that in the heating and ventilation equipment provided by the embodiments of the present application, the first electric control box 100 and the second electric control box 300 are arranged relatively independently, and the first circuit assembly 120 and the second circuit assembly 320 are arranged in the first electric control box 100 and the second electric control box 300 respectively according to the difference in heat generation, so that the first circuit assembly 120 in the first electric control box 100 located on the first partition plate 220 has high heat dissipation efficiency, and the second electric control box 300 can accommodate the second circuit assembly 320 with low heat dissipation requirement, which is arranged in the compressor cavity 212, thereby fully utilizing the space inside the cabinet 210, improving the space utilization, and then the second circuit assembly 320 with relatively high heat generation can dissipate heat by the airflow in the fan cavity 211, so that the electric control components of the heating and ventilation equipment can be maintained in a suitable working temperature range.

[0067] Next, the specific installation method and installation structure of the second electric control box 300 in the compressor cavity 212 will be described in detail.

[0068] Please refer to FIG. 1 to FIG. 6 In a possible implementation, the second electric control box 300 can be located on the side of the compressor cavity 212 away from the first partition plate 220, so that the second electric control box 300 with low heat dissipation requirement can fully utilize the space in the compressor cavity 212 and improve the space utilization.

[0069] It can be understood that the second shell 310 can be vertically arranged in the compressor cavity 212, and the shell wall of the second shell 310 can be arranged as much as possible to fit the cavity wall of the compressor cavity 212.

[0070] In some embodiments, the second partition plate 250 is arranged in the compressor cavity 212, the compressor 240 is located between the first partition plate 220 and the second partition plate 250, and the second electric control box 300 is connected to the side of the second partition plate 250 away from the compressor 240.

[0071] It can be understood that the weight of the second electric control box 300 is borne by the second partition plate 250. In addition, the second shell 310 can be movably connected with the second partition plate 250, so that the second electric control box 300 can be taken out of the compressor cavity 212, thereby facilitating the maintenance of the second electric control box 300.

[0072] In some embodiments, the second shell 310 can include a shell body 311 and a cover plate 312, the shell body 311 has an opening 3113 on the side away from the first partition plate 220, and the cover plate 312 is arranged on the opening 3113, and the shell body 311 and the cover plate 312 form a sealed containing cavity, and the second circuit assembly 320 is located in the containing cavity.

[0073] Among them, the second circuit assembly 320 can be connected on the inner wall of the side of the shell body 311 close to the first partition plate 220, and the cover plate 312 is sealingly connected with the shell body 311, so that the second electric control box 300 has good waterproof, dustproof and refrigerant-proof effect, keeps the internal space of the second shell 310 clean and dry, and can prevent the refrigerant from entering the second electric control box 300 to cause the risk of burning or explosion when the refrigerant leaks in the heating and ventilation equipment.

[0074] It should be noted that the box body 210 has a top plate, when the top plate is opened, the internal space of the fan cavity 211 and the compressor cavity 212 can be exposed, and the second electric control box 300 can be installed in the compressor cavity 212 in a detachable manner, so that the second electric control box 300 can be disassembled after the top plate is opened.

[0075] In some embodiments, the side of the shell body 311 can be provided with a hanging part 3114, and the inner wall of the box body 210 is provided with a supporting part, the hanging part 3114 is movably inserted with the supporting part, or the hanging part 3114 is rotatably connected with the supporting part, which can ensure the reliable connection between the second shell 310 and the box body 210, improve the convenience of disassembling or opening the second shell 310 from the box body 210, and facilitate the maintenance operation.

[0076] It can be understood that when the hanging part 3114 is movably inserted with the supporting part, the second electric control box 300 can be placed into the compressor cavity 212 from the top of the box body 210 in the vertical direction, or taken out of the compressor cavity 212 in the vertical direction. For example, the inner walls on both sides of the side of the compressor cavity 212 away from the first partition plate 220 can be provided with guide grooves, and the two sides of the second shell 310 can be opposite to the guide grooves, and the guide grooves can guide the movement of the second electric control box 300 when it is inserted and assembled in the compressor cavity 212.

[0077] When the hanging part 3114 is connected with the supporting part, the hanging part 3114 can play the role of a rotating shaft. When the hanging part 3114 is connected with the supporting part, the hanging part 3114 can have a certain gap with the supporting part, thereby reserving space for the rotation of the hanging part 3114 relative to the supporting part.

[0078] In some embodiments, the hanging part 3114 can be multiple, and the multiple hanging parts 3114 can be distributed along the side edges of the shell body 311, so that the second shell 310 has multiple bearing stress points on the box 210, thereby improving the stability of the installation of the second control box 300. The two side edges of the shell body 311 extending in the vertical direction can be provided with the hanging part 3114, so that the two sides of the second shell 310 can be effectively supported.

[0080] For example, the length of the first folded edge 3115 matches the length of the side edge of the second shell 310, and the mounting hole 3115a can be multiple. The multiple first mounting holes 3115a can be spaced along the length direction of the first folded edge 3115.

[0081] In some embodiments, the edge of the cover plate 312 can be attached to the first folded edge 3115, and the cover plate 312 can be provided with a relief gap 3121 opposite the mounting hole 3115a. While preventing interference between the cover plate 312 and the fastener, the cover plate 312 and the shell body 311 have good sealing performance.

[0082] It can be understood that the cover plate 312 can be a flat plate structure, the first folded edge 3115 can be parallel to the cover plate 312, the shape of the cover plate 312 can match the shape of the opening 3113 of the shell body 311, and the size of the cover plate 312 can be slightly larger than the size of the opening 3113.

In addition, when the refrigerant of the heating and ventilation equipment leaks, the closed first electric control box 100 can prevent the refrigerant from entering the inside of the first electric control box 100, so as to avoid the risk of burning or explosion.

[0103] It can be understood that, since the containing cavity of the first shell 110 is a closed space, the heat of the control circuit board can be transmitted to the heat conduction structure of the first shell 110 through heat conduction, and the heat conduction structure can be cooled through the airflow in the fan cavity 211, so that the first electric control box 100 can be directly cooled through the airflow in the fan cavity 211, and the airflow for cooling does not need to pass through the compressor cavity 212, thereby shortening the cooling path and improving the cooling efficiency.

[0104] In some embodiments, the first shell 110 is provided with a first heat dissipation part 112 on the side wall facing the fan cavity 211, and the first heat dissipation part 112 extends into the fan cavity 211.

[0105] The fan cavity 211 can be provided with a fan 230, and the compressor cavity 212 can be provided with a compressor 240, a pipeline and other structures.

The first electric control box 100 can further include a wire outlet pipe 140, which is arranged in the wire outlet 130 and is in sealed connection with the first shell 110. In this way, by arranging the wire outlet pipe 140, the control circuit board can pass out wires from the wire outlet pipe 140, realize the electrical connection between the control circuit board and the second circuit assembly 320 in the second electric control box 300 and other components of the device main body 200, so as to realize signal transmission between the first electric control box 100 and the second electric control box 300 and control the device main body 200, and by arranging the wire outlet 130, the sealing assembly of the wire outlet pipe 140 on the first shell 110 can be realized, so as to ensure the sealing performance of the first electric control box 100 at the wire outlet 130.
