[0033] In some embodiments of the utility model, as shown in Figure 1 As shown in the drawings, a heating and ventilation equipment 100 is provided, which comprises a box body 10, a control cabinet 20 and a sealing element 30. Among them, the box body 10 is specifically the shell 11 structure of the heating and ventilation equipment, and the heating and ventilation equipment includes but is not limited to the whole wall-mounted liquid-cooled energy storage air conditioning unit, the vertical cabinet type air conditioner, the window type air conditioner, the ceiling type air conditioner. The box body 10 is the whole machine shell 11 in the above-mentioned air conditioning equipment, and the box body 10 bears the core components of the whole equipment and provides a relatively stable, safe installation space for the internal control cabinet 20 and other components.

[0034] The box body 10 has a containing cavity 101, the box body 10 is provided with a wire outlet 104 communicated with the containing cavity 101, the control cabinet 20 is arranged in the containing cavity 101, the inside of the control cabinet 20 is limited to the electric control cavity 21, and a plurality of wire holes 22 are arranged, the wire holes 22 are communicated with the electric control cavity 21, and the wire holes 22 are key channels for realizing cable connection. Various electrical elements in the control cabinet 20, such as controllers, relays, switches and the like, need to be connected with external equipment to realize power transmission, signal interaction and the like. The cable enters the control cabinet 20 through the wire hole 22 and is connected with the internal elements, so that the whole system constitutes a complete electrical circuit, and normal operation of the equipment is ensured. Along the through direction of the wire hole 22, the plurality of wire holes 22 are oppositely arranged with the wire outlet 104. In the actual electrical system, the cable needs to be connected from the inside of the control cabinet 20 to the external equipment, and the oppositely arranged wire holes 22 and wire outlet 104 can make the cable pass through the wire holes 22 and wire outlet 104 in sequence, so as to realize wiring in the shortest and most direct path, reduce the bending and winding of the cable. And for construction personnel and maintenance personnel, the oppositely arranged wire holes 22 and wire outlet 104 are more convenient to operate. When installing, the construction personnel can quickly find the corresponding wire hole 22 and wire outlet 104 for cable connection, improving the installation efficiency; when maintaining the equipment, the maintenance personnel can clearly judge the cable direction, quickly locate the fault point, and conveniently perform the inspection, replacement and the like of the cable.

[0035] Further, the sealing member 30 is annularly arranged between the inner wall of the control cabinet 20 and the inner wall of the cavity 101, and is annularly arranged outside the plurality of wire passing holes 22 and the wire outlet 104. One end of the sealing member 30 is sealingly connected to the outer wall of the control cabinet 20, and the other end of the sealing member 30 is sealingly connected to the inner wall of the cavity 101. Thus, the sealing member 30 forms an overall sealing structure between the control cabinet 20 and the inner wall of the cavity 101. The sealing structure formed by the sealing member 30 separates the wire passing holes 22 and the wire outlet 104 from the cavity 101, thereby achieving sealing of the wire passing holes 22 in the cavity 101, preventing dust and liquid in the cavity 101 from entering the interior of the control cabinet 20 through the wire passing holes 22, and prolonging the service life of the control cabinet 20 and the entire heating and ventilation equipment. In addition, compared with the sealing mode of the conventional waterproof joint or aviation joint, the heating and ventilation equipment 100 is not limited by factors such as the magnetic ring on the cable, the large terminal, and the plug-in port wire group, and has stronger applicability. Furthermore, compared with the form of using a wire passing rubber ring and sealing glue, this structure is more convenient to operate during production, and is more convenient to maintain in the later period. The production and maintenance costs are reduced, and the work efficiency is improved.

[0036] In some embodiments, the sealing member 30 can be a rubber O-ring, and the material of the rubber O-ring includes but is not limited to nitrile rubber and fluororubber. The rubber O-ring has good elasticity and wear resistance, and can provide reliable sealing effect in a small installation space. The O-ring can be directly embedded in the groove around the wire passing hole 22 and the wire outlet 104, and form a sealed space between the control cabinet 20 and the inner wall of the cavity 101, which is isolated from the cavity 101. The wire passing hole 22 is in communication with the sealed space formed by the electric control cavity 21 and the sealing member 30, and the cable passing through the wire passing hole 22 to the wire outlet 104 is located in the sealed space.

[0037] In some embodiments, the sealing member 30 can be a rubber O-ring, and the material of the rubber O-ring includes but is not limited to nitrile rubber and fluororubber. The rubber O-ring has good elasticity and wear resistance, and can provide reliable sealing effect in a small installation space. The O-ring can be directly embedded in the groove around the wire passing hole 22 and the wire outlet 104, and form a sealed space between the control cabinet 20 and the inner wall of the cavity 101, which is isolated from the cavity 101. The wire passing hole 22 is in communication with the sealed space formed by the electric control cavity 21 and the sealing member 30, and the cable passing through the wire passing hole 22 to the wire outlet 104 is located in the sealed space.

[0038] In other embodiments, the seal 30 may also be configured as a seal 30 with a metal outer shell and an internal filling of rubber or other elastic sealing materials. The metal outer shell provides good mechanical strength and corrosion resistance, while the internal elastic material ensures sealing performance. The HVAC equipment 100 is suitable for harsh working environments, such as locations with high temperature, high humidity, or chemical corrosion risks. For example, in the cabinet-type air conditioning control cabinet 20 used in chemical plants, the seal 30 can resist the erosion of chemical substances, ensuring that the protective performance of the control cabinet 20 is not affected.

[0039] In some embodiments, such as Figure 1 As shown, the enclosure 10 includes a shell 11 and a partition 12. The shell 11 forms the external outline of the entire enclosure 10, and its interior is hollow, providing a space for the various components of the HVAC equipment. The partition 12 is installed inside the shell 11 and divides the interior of the shell 11 into two functional areas: a cavity 101 and a component cavity 103. The component cavity 103 is mainly used to install the core operating components of the HVAC equipment, such as the compressor. As a key component for cooling or heating in HVAC equipment, the stable operation of the compressor is crucial to the performance of the equipment. Placing the compressor and other components in the component cavity 103 allows them to work in a relatively independent space, avoiding interference with other components, and also facilitates centralized maintenance and management of these components. The cable outlet 104 is located on the partition 12 and serves as a communication channel between the cavity 101 and the component cavity 103. The cable outlet 104 not only realizes the physical connection between the cavity 101 and the component cavity 103, but more importantly, it also provides the necessary path for the passage of cables. Through the outlet 104, the cable leading from the control cabinet 20 can be smoothly connected to the compressor and other equipment in the device cavity 103, thereby realizing power transmission and signal interaction and ensuring the normal operation of the entire HVAC equipment. The seal 30 is sandwiched between the control cabinet 20 and the partition 12. The interior of the housing 11 is hollow, and the partition 12 is located inside the housing 11 and divides the interior of the housing 11 into the cavity 101 and the device cavity 103. The device cavity 103 is used to install the compressor and other devices of the HVAC equipment. The outlet 104 is located on the partition 12 and connects the cavity 101 and the device cavity 103. The seal 30 is sandwiched between the control cabinet 20 and the partition 12.

[0040] In some embodiments, the sealing member 30 comprises a body portion and first and second sealing surfaces arranged at opposite ends of the body portion along the through direction of the wire passing hole 22. The body portion, as the main supporting part of the sealing member 30, has a certain thickness and width, which can ensure sufficient elastic deformation space to achieve good sealing effect and maintain the stability of the structure. For example, in some exemplary embodiments, the thickness of the body portion can be between 5 mm and 10 mm, and the width is adaptively adjusted according to the distribution and size of the wire passing hole 22 to ensure that it can completely cover the area between the wire passing hole 22 and the partition plate 12. The first sealing surface is connected to the outer wall surface of the control cabinet, and the second sealing surface is connected to the partition plate 12. In actual installation, the sealing member 30 is sleeved around the wire passing hole 22, and the first sealing surface is tightly connected to the outer wall surface of the control cabinet and the second sealing surface is tightly connected to the partition plate 12 by appropriate external force, thereby forming an effective sealing barrier between the control cabinet and the partition plate 12, effectively preventing air, dust and possibly existing liquid and other substances in the cavity 101 from entering the interior of the control cabinet through the wire passing hole 22, and also preventing the entry into the device cavity 103 through the wire outlet 104, thereby protecting the clean and dry environment inside the control cabinet 20, and also serving as a buffer and fixing function to enhance the stability of the entire equipment structure.

[0041] In some embodiments, the control cabinet 20 is provided with a first connecting portion 23, the partition plate 12 is provided with a second connecting portion 13 arranged opposite to the first connecting portion 23, and the heating and ventilation equipment 100 further comprises a connecting member 40 (not shown in the figure) connected to the first connecting portion 23 and the second connecting portion 13 respectively, so as to fix the control cabinet 20 to the partition plate 12 and apply a pre-tightening force to the control cabinet 20 towards the partition plate 12.

[0042] In an exemplary embodiment, as shown in Figure 3 The position of the first connecting portion 23 on the control cabinet 20, the number of the first connecting portion 23 can be one or multiple, when the number of the first connecting portion 23 is multiple, the multiple first connecting portions 23 are arranged around the periphery of the wire passing hole 22, and the shape of the multiple first connecting portions 23 is configured as multiple uniformly distributed protruding block structures, each block structure is provided with a threaded hole, the threaded hole is a blind hole and does not communicate with the electric control cavity 21. The second connecting portion 13 on the partition plate 12, the number of the second connecting portion 13 matches the number of the first connecting portion 23, and the second connecting portion 13 is in precise correspondence with the position of the first connecting portion 23, and the shape of the second connecting portion 13 can be a through hole matched with the protruding block of the first connecting portion 23 for facilitating the penetration of the connecting member 40.

[0043] In addition, the warm air conditioning device 100 also includes a connecting piece 40, which can be selected from high-strength bolts. The bolts are sequentially threaded through the through hole of the second connecting part 13 and the threaded hole of the first connecting part 23, and then tightened. During the tightening of the bolts, the bolts will exert a pre-tightening force on the control cabinet 20 towards the middle partition plate 12, which makes the sealing piece 30 more tightly pressed between the control cabinet 20 and the middle partition plate 12, further enhancing the sealing effect and effectively preventing air, dust and possibly existing liquids and other substances in the cavity 101 from entering the electric control cavity 21 or the device cavity 103. Secondly, in terms of structural stability, the firm connection makes the control cabinet 20 and the middle partition plate 12 form a stable whole, reducing the displacement or shaking of the control cabinet 20 during the operation of the device due to factors such as vibration, and improving the stability of the entire device structure. Furthermore, the above-mentioned connection method is relatively simple to operate during installation and maintenance, and only requires conventional tools to complete the disassembly and installation of the bolts, reducing the difficulty of construction and maintenance, improving work efficiency, and also reducing the risk of damage to the device due to frequent maintenance.

[0044] In another exemplary embodiment, please refer to Figure 1 and Figure 2 , the first connecting part 23 is configured as a first connecting hole 231, and the second connecting part 13 is configured as a second connecting hole 131. Along the through direction of the wire passing hole 22, the first connecting hole 231 is oppositely arranged with the second connecting hole 131. The positions of the first connecting hole 231 are uniformly distributed in a certain area of the periphery of the wire passing hole 22, and the size of the first connecting hole 231 is determined according to the size of the connecting piece 40, which is slightly larger than the outer diameter of the connecting piece 40 to ensure that the connecting piece 40 can smoothly pass through, while not generating too large a gap to affect the stability of the connection. The size of the second connecting hole 131 on the middle partition plate 12 is consistent with that of the first connecting hole 231 to ensure that the connecting piece 40 can smoothly pass through. Please refer to Figure 2 and Figure 4 , the sealing piece 30 is additionally provided with a third connecting hole 301 through which the first sealing surface and the second sealing surface pass. Along the through direction of the wire passing hole 22, the two ends of the third connecting hole 301 are oppositely arranged with the first connecting hole 231 and the second connecting hole 131, respectively. In actual installation process, the connecting piece 40 can be a bolt and a nut. The bolt is sequentially threaded through the second connecting hole 131, the third connecting hole 301 and the first connecting hole 231, and then the nut is tightened at one end of the first connecting hole 231, so as to stably fix the control cabinet 20 to the middle partition plate 12.

[0045] In this embodiment, when the bolt is tightened, uniform pressure can be generated on the sealing member 30, so that the first sealing surface of the sealing member 30 is tightly attached to the outer wall surface of the control cabinet 20, and the second sealing surface is tightly attached to the partition plate 12, further improving the reliability of the sealing, effectively preventing air, dust, and possibly existing liquid and other substances between the cavity 101 and the device cavity 103 from entering the electric control cavity 21 and the device cavity 103. From the structural stability, the control cabinet 20 and the partition plate 12 are tightly connected into a whole through the connecting piece 40, greatly enhancing the stability of the entire equipment structure, effectively reducing the influence of vibration, displacement and other factors on the control cabinet 20 during equipment operation, and ensuring long-term stable operation of the equipment. It should be noted that the above connection method is relatively simple to operate, and only common tools are required to complete the disassembly and installation of the bolt, greatly reducing the difficulty of construction and maintenance, improving work efficiency, and reducing the risk of damage to the equipment due to frequent maintenance., provides a strong guarantee for the long-term stable operation of the equipment.

[0046] In some embodiments, the shell 11 is provided with an air inlet (not shown in the figure) and an air outlet (not shown in the figure) arranged opposite to each other, the air inlet and the air outlet are respectively connected with the cavity 101, and the cavity 101 is connected with the outdoor side through the air inlet and the air outlet, that is, the cavity 101 is essentially an air duct in the heating and ventilation equipment.

[0047] Understandably, in other embodiments, the cavity 101 can also be any inner cavity of other parts of the heating and ventilation equipment, as long as it is used for installing the control cabinet.

[0048] In some embodiments, the heating and ventilation equipment 100 further comprises a plurality of wire protection rubber rings (not shown in the figure), which are installed one by one in the wire holes 22. The wire protection rubber rings can protect the cables entering and exiting the control cabinet, and the installation of the wire protection rubber rings in the wire holes 22 can ensure that the magnetic ring and the wiring terminal on the wire body can easily enter and exit the control cabinet.

[0049] In some embodiments, as Figure 5 and Figure 6As shown, the cabinet 10 includes a shell and a partition 12, the shell includes a bottom plate 1001, a top cover 1002, a front panel (not shown in the figure), a left side plate 1003 and a right side plate 1004, the bottom plate, the top cover, the front panel, the left side plate and the right side plate together enclose a cavity 101, the partition 12 is arranged in the cavity 101, the partition 12 is connected with the front panel, the bottom plate 1001 and the top cover 1002 respectively, and the partition 12 is arranged between the left side plate 1003 and the right side plate 1004 and separates the cavity 101 into a first chamber 105 and a second chamber 106. The first chamber 105 is used for accommodating heat exchangers and fans and the like. The heat exchanger is a core component for realizing heat exchange. In the process of refrigeration or heating, the heat exchanger adjusts the temperature of the air by heat transfer with the air. The fan drives the air to flow in the first chamber 105, so that the air can fully contact the heat exchanger and improve the heat exchange efficiency. The control cabinet 20 is installed in the second chamber 106, and the outlet 104 is arranged on the right side plate 1004 of the shell and communicates the second chamber 106 with the external environment. The outlet 104 provides a channel for the electrical elements in the control cabinet 20 to connect with external equipment. Through the outlet 104, the cable can transmit power and signals to the external equipment, realizing the interaction and cooperative work of the equipment and the external system.

[0050] The sealing element 30 is clamped between the control cabinet 20 and the inner wall of the right side plate 1004, and the sealing element 30 is annularly arranged outside the plurality of wire holes 22 and the outlet 104, so that the sealing element 30 forms an overall sealing structure between the control cabinet 20 and the inner wall of the right side plate 1004, and the sealing structure formed by the sealing element 30 isolates the wire holes 22 and the outlet 104 from the second chamber 106, thereby realizing the sealing of the wire holes 22 in the second chamber 106. When the second chamber has a leak of flammable refrigerant gas, the refrigerant gas is prevented from entering the interior of the control cabinet through the wire holes 22 of the control cabinet 20, thereby prolonging the service life of the control cabinet 20 and the entire heating and ventilation equipment.

[0051] According to the embodiment of the utility model, the heating and ventilation equipment further includes a heat exchanger, a compressor, a fan and the like. The heat exchanger is a core component for realizing heat exchange.

The fan includes a centrifugal fan, an axial flow fan and the like. The fan functions to promote the flow of air in the equipment. The fan is arranged in the cavity 101. The airflow generated by the fan drives the air to flow from the air inlet into the cavity 101, passes through the heat exchanger and then flows out from the air outlet, realizing the heat exchange between indoor and outdoor air.

[0052] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
