For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0026] The specific embodiments of the electrical component mounting plate of the present application will be described below in conjunction with Figs. 1-3 The specific embodiments of the electrical component mounting plate of the present application will be described below in conjunction with

[0027] The present application provides an electrical component mounting plate, comprising: a weak current mounting plate 10, the upper surface of which has a weak current area 11 for arranging low-voltage electrical components; a strong current mounting plate 20, the upper surface of which has a strong current area 21 for arranging high-voltage electrical components, the strong current mounting plate 20 being parallel to the weak current mounting plate 10; a connecting plate 30, which is connected vertically to the weak current mounting plate 10 and the strong current mounting plate 20 respectively, the weak current mounting plate 10, the connecting plate 30 and the strong current mounting plate 20 forming a stepped structure to form a height difference between the weak current mounting plate 10 and the strong current mounting plate 20 based on the height of the connecting plate 30. The electrical component mounting plate realizes effective isolation of strong and weak currents through the layered stepped structure, solves the problem of electromagnetic interference, and thus ensures the accuracy of controller signal acquisition and the stable operation of the entire air conditioning system.

[0028] Specifically, the upper surface of the weak current installation plate 10 is planned to have a weak current area 11 for arranging low-voltage electrical components (such as controllers, sensors, small intermediate relays, and other low-voltage electrical components with a rated working voltage of DC 24V and AC 220V). Low-voltage electrical components are usually responsible for precise control tasks such as data acquisition, signal processing, and command output, and are highly sensitive to electromagnetic environments. The strong current installation plate 20 is arranged in parallel with the weak current installation plate 10, and the upper surface thereof is arranged with a strong current area 21 for installing high-voltage electrical components (such as circuit breakers, frequency converters, contactors, and other high-voltage electrical components with a rated working voltage of AC 380V). Strong current components usually carry large currents and high voltages, and generate strong electromagnetic fields during operation. The two installation plates are connected by a connecting plate 30. The connecting plate 30 is perpendicular to the weak current installation plate 10 and the strong current installation plate 20, and forms a stepped three-dimensional structure. Through the height difference of the connecting plate 30, a physical gap is created between the weak current installation plate 10 and the strong current installation plate 20, thereby significantly enhancing the isolation effect between strong and weak currents in space.

[0029] In view of the problem that in existing air conditioning systems, strong and weak current components are often isolated by wire slots, but the isolation effect is not good and is easily affected by electromagnetic interference, the present application adopts the above-mentioned layered stepped installation plate structure. The layered stepped electrical component installation plate not only effectively avoids the direct action of the electromagnetic field generated by the strong current components on the weak current components, significantly reduces the influence of electromagnetic interference on the signal acquisition and processing of weak current equipment such as controllers, ensures the accurate measurement of key parameters such as temperature and pressure, and further improves the control accuracy and response speed of the air conditioning system; at the same time, it also fundamentally improves the rationality of the layout of strong and weak current components and the electrical safety, providing a strong guarantee for the long-term stable operation of the air conditioning system.

[0030] The height of the connecting plate 30 is preferably 100mm or more, to form a height difference of 100mm or more between the weak current installation plate 10 and the strong current installation plate 20. By creating a sufficient height difference, effective isolation of strong and weak currents is achieved, electromagnetic interference is reduced, the installation space requirements of electrical components are met, and the overall heat dissipation conditions are optimized, thereby ensuring the stable and efficient operation of the air conditioning system.

[0031] Further, the application provides an electrical component mounting plate, wherein the strong current mounting plate 20 is provided with an insulation groove 22 connected to the weak current area 11, the insulation groove 22 is in a tubular structure; the control cable and / or communication cable between the low-voltage electrical component and the high-voltage electrical component extends from the weak current area 11 to the strong current area 21 through the insulation groove 22. The strong current mounting plate 20 is provided with an insulation groove 22 connected to the weak current area 11, the insulation groove 22 is in a tubular structure, so as to provide a safe and reliable transmission channel for the control cable and / or communication cable between the low-voltage electrical component (such as a controller) and the high-voltage electrical component (such as a frequency converter). When the controller needs to collect the running state or feedback signal of the high-voltage electrical component such as the frequency converter, the related control cable can be laid through the pre-set tubular insulation groove 22. The insulation groove 22 not only plays a role of physical isolation to prevent the directly exposed cable from being directly interfered by the electromagnetic field of the strong current area 21, but also effectively wraps the cable through the tubular structure, so as to further reduce the electromagnetic coupling between the cable and the surrounding environment, and improve the purity and stability of signal transmission. As the insulation groove 22, the material is preferably good in insulation performance, such as being made of high-temperature-resistant, anti-aging, and excellent electrical insulation performance engineering plastics or ceramics, or being made of metal material and being grounded to prevent electric leakage.

[0032] The application provides a special transmission path with good electromagnetic shielding effect for the control cable and / or communication cable between the low-voltage electrical component and the high-voltage electrical component through the tubular insulation groove 22 arranged on the strong current mounting plate 20. Preferably, according to the application, the insulation groove 22 is a metal pipe welded on the upper surface of the strong current mounting plate 20, and the insulation groove 22 is grounded; and / or the inner side wall or outer side wall of the insulation groove 22 is provided with a tin paper layer to improve the signal insulation performance.

[0033] The metal pipe is fixed on the upper surface of the strong current mounting plate 20 through welding, so as to ensure the firm connection between the metal pipe and the mounting plate, and also form a continuous and complete shielding layer to effectively block the influence of the external electromagnetic field on the internal cable. The insulation groove 22 made of the metal pipe is grounded, when the electromagnetic interference tries to enter the inside through the metal pipe, the interference current will be rapidly discharged along the grounding path instead of flowing into the cable, so as to effectively protect the signal integrity of the internal cable and improve the shielding performance of the insulation groove 22, and provide a solid electromagnetic protection barrier for the control cable.

[0034] In order to further improve the signal insulation performance of the insulation groove 22, a layer of tin paper can be arranged on the inner side wall or the outer side wall of the insulation groove 22. The tin paper has excellent electrical conductivity and good electromagnetic shielding effect, can effectively reflect or absorb electromagnetic waves, and reduce the penetration of electromagnetic energy. The addition of the tin paper layer in the insulation groove 22 is equivalent to adding another shielding layer on the basis of the original metal tube shielding, forming a double-layer or even multi-layer shielding effect, and enhancing the electromagnetic protection of the control cable.

[0035] According to the electric appliance element mounting plate provided by the application, at least part of the strong current cable connected to the high-voltage electric appliance element passes through the connecting plate 30 and is arranged on the side of the low-voltage mounting plate 10 facing away from the low-voltage area 11. By arranging the running path of the strong current cable to pass through the connecting plate 30 and be arranged on the side of the low-voltage mounting plate 10 facing away from the low-voltage area 11, the separation of the strong current cable and the low-voltage cable is successfully realized, the height difference of the mounting plate is effectively utilized, and both electromagnetic interference is avoided and the thickness of the cabinet is saved.

[0036] Specifically, at least part of the strong current cable connected to the high-voltage electric appliance element (such as a frequency converter) is arranged to pass through the connecting plate 30 and be arranged on the side of the low-voltage mounting plate 10 facing away from the low-voltage area 11. By arranging the running path of the strong current cable on the back of the low-voltage mounting plate 10, the strong current cable and the low-voltage electric appliance element (such as a controller) on the low-voltage mounting plate 10 are avoided from being directly adjacent or intersecting, and the effective separation of the strong current cable and the low-voltage cable in space is realized. In the traditional strong and weak current integrated cabinet design, the strong current cable and the low-voltage cable are often arranged in the same plane or adjacent planes, and a large space needs to be reserved to avoid mutual interference, which may lead to an increase in the thickness of the cabinet. The application ingeniously utilizes the three-dimensional space between the mounting plates by arranging the strong current cable on the back of the low-voltage mounting plate 10, reduces the space required for cable arrangement in the cabinet, and thus helps to reduce the overall thickness of the cabinet and realize the miniaturization and compactness of the equipment.

[0037] According to the electric appliance element mounting plate provided by the application, the connecting plate 30 is provided with a first connector 31 for connecting the strong current cable located in the strong current area 21, and the low-voltage mounting plate 10 is provided with a second connector 12 corresponding to the first connector 31, and the first connector 31 and the second connector 12 are connected by a cable on the side of the low-voltage mounting plate 10 facing away from the low-voltage area 11. By arranging the first connector 31 on the connecting plate 30, the second connector 12 corresponding to the first connector 31 on the low-voltage mounting plate 10, and connecting by a cable on the side of the low-voltage mounting plate 10 facing away from the low-voltage area 11, not only the safe and reliable power and signal transmission between the strong current area 21 and the low-voltage area 11 is realized, but also the strong and weak current isolation is further strengthened, and the wiring structure is optimized.

[0038] The cable connection part between the first connector 31 and the second connector 12 is away from the weak current area 11, further avoiding close contact between the strong current cable and the weak current element, strengthening the strong and weak current isolation effect, and effectively suppressing electromagnetic interference. Moreover, through the combined connection of the connector and the cable, the wiring of the strong current cable and the back of the weak current mounting plate 10 is more regular, facilitating later maintenance and troubleshooting. The use of the connector makes the connection between the strong current and the weak current more flexible. When the cable length needs to be adjusted or the equipment needs to be replaced, the connector only needs to be reconnected, without the need to change the hard wiring, greatly simplifying the installation and maintenance process.

[0039] The strong and weak current integrated cabinet of the application innovatively realizes the isolation of the strong current cable and the weak current area 11 through directional wiring and connector connection, ensures that the controller can still accurately collect signals without interference when the strong current system is running. The strong current cable is connected through the second connector 12 on the back of the weak current mounting plate 10 and extends to the first connector 31 of the connecting plate 30, avoiding the weak current area 11, ensuring physical isolation, and effectively blocking electromagnetic interference. During maintenance, only the first and second connectors need to be operated, without the need to disassemble the cabinet maintenance opening, simplifying the process, reducing downtime, and greatly improving equipment maintenance efficiency and availability.

[0040] According to the electric element mounting plate provided by the application, the number of the first connector 31 and the second connector 12 is multiple; each first connector 31 and second connector 12 has a plurality of corresponding terminal heads. Through the configuration of multiple connectors and multiple terminal heads, the demand of complex electrical connection of the air conditioning system is met, and the versatility and expansibility of the mounting plate are improved.

[0041] The number of the first connector 31 and the second connector 12 is multiple, which can simultaneously process the connection of multiple strong current cables and weak current systems, and is suitable for scenes containing multiple high-voltage electric elements (such as multiple frequency converters) or requiring multiple power distribution in the air conditioning system. Each first connector 31 and the corresponding second connector 12 is equipped with multiple terminal heads, so that each group of connectors can simultaneously connect multiple wires or cables to respectively transmit different power or signals. The multiple terminal head design between the first connector 31 and the second connector 12 maintains a one-to-one correspondence, ensuring the accuracy and integrity of power or signal transmission between each pair of connectors.

[0042] The application preferably adopts a detachable terminal head design to improve the convenience and flexibility of strong current cable maintenance. When troubleshooting or adjusting the line of the strong current cable, the continuity between the first connector 31 on the connecting plate 30 and the corresponding terminal head of the second connector 12 on the weak current mounting plate 10 can be directly detected by using a multimeter, without the need to disassemble the terminal head, to quickly determine whether the cable has problems such as short circuit, open circuit or misconnection. If it is confirmed that the cable has problems such as damage or wiring error, the maintenance personnel can easily disassemble the terminal head, rewire or correct the wiring error, and then fix the repaired terminal head to complete the fault repair or line adjustment work, greatly simplifying the maintenance process and shortening the maintenance time.

[0043] The terminal head preferably adopts a double-sided structure design, both sides of which can be connected to the cable, so that a single terminal head can realize reliable conduction of the cable, improving the wiring density and space utilization. Preferably, the terminal head can support a wide range of cable cross-sectional areas, from a minimum of 4mm2 to a maximum of 120mm2, which can adapt to the connection requirements of different specifications of strong current cables in air conditioning systems.

[0044] According to the electric element mounting plate provided by the application, the connecting plate 30 is provided with a heat dissipation opening 32 for heat dissipation of the strong current area 21. Through the arrangement of the heat dissipation opening 32, an effective heat dissipation path is provided for the high-voltage electric element (such as a frequency converter) mounted on the strong current mounting plate 20, so as to ensure that it maintains an appropriate working temperature during long-time operation, avoiding performance degradation, shortened service life or even failure shutdown due to overheating.

[0045] The heat dissipation opening 32 is arranged on the connecting plate 30, and its specific position, shape and size can be reasonably planned according to the actual heat dissipation demand of the strong current area 21 and the air flow condition inside the cabinet. The existence of the heat dissipation opening 32 enables the external cold air to enter the strong current area 21, cool the heating elements, and then discharge the generated hot air, forming an effective heat dissipation cycle.

[0046] Further, in order to strengthen the thermal isolation between the strong current and weak current areas 11 and prevent the hot air flow generated by the strong current area 21 from affecting the normal operation of the weak current elements, according to the electric element mounting plate provided by the application, a first flow guide plate 13 is arranged at the connecting position of the weak current mounting plate 10 and the connecting plate 30, and an obtuse angle structure is formed between the first flow guide plate 13 and the connecting plate 30 towards the side of the strong current area 21. The flow guide plate and the connecting plate 30 jointly constitute an obtuse angle structure towards the side of the strong current area 21, which ingeniously utilizes the principle of aerodynamics to guide and block the flow direction of the hot air flow. The specific angle between the first flow guide plate 13 and the connecting plate 30 can be set according to the specific application environment, and is preferably 160°.

[0047] Specifically, the obtuse angle structure formed by the first flow guide plate 13 and the connecting plate 30 can guide the upward hot air flow generated by the strong electric region 21 to flow along a predetermined path, avoiding its direct diffusion to the weak electric region 11. Through the blocking effect of the first flow guide plate 13, the high-temperature hot air flow of the strong electric region 21 is effectively prevented from directly invading the weak electric region 11, reducing the influence of heat conduction and convection on weak electric elements, further improving the thermal isolation effect between strong and weak electricity, ensuring that weak electric elements (such as controllers, sensors, etc.) are not affected by high temperature, and maintaining stable signal acquisition and processing performance.

[0048] At least a part of the heat dissipation port 32 is preferably arranged below the first flow guide plate 13. The presence of the first flow guide plate 13 not only blocks the diffusion of hot air flow to the weak electric region 11, but also plays a role in converging the hot air flow. The heat dissipation port 32 is located below it, further strengthening this convergence effect, so that more hot air flow can be concentrated and directed to the heat dissipation port 32, thereby more efficiently exhausting the cabinet.

[0049] When traditional multiple frequency converters are stacked, the hot air discharged from the lower end of the frequency converter is often sucked into the air inlet of the upper end of the frequency converter. This condition can cause the hot air to circulate repeatedly, seriously affecting the heat dissipation efficiency of the upper end of the frequency converter, and thus shortening its service life. According to the electric element mounting plate provided by the present application, a second flow guide plate 23 is arranged on the strong electric mounting plate 20 in the strong electric region 21; an acute angle structure is formed between the second flow guide plate 23 and the strong electric mounting plate 20 towards the side of the connecting plate 30; high-voltage electric elements are distributed on both sides of the second flow guide plate 23; and the height of the second flow guide plate 23 is lower than that of the first flow guide plate 13 relative to the strong electric mounting plate 20. The angle between the second flow guide plate 23 and the strong electric mounting plate 20 can be flexibly set according to the specific application environment, and is preferably 45°.

[0050] As shown by the two dotted arrows, Fig. 2 The two dotted arrows respectively show the heat flow discharge paths of the high-voltage electric elements on the front and back sides of the second flow guide plate 23. The second flow guide plate 23 and the strong electric mounting plate 20 together form an acute angle structure towards the side of the connecting plate 30 to guide the hot air flow generated by the high-voltage electric elements such as frequency converters. When the frequency converter on the back side of the second flow guide plate 23 is working, the hot air released from its air outlet can pass over the air inlets of other frequency converters in front of the second flow guide plate 23 under the guidance of the second flow guide plate 23, avoiding the direct backflow of hot air to the interior of the adjacent front frequency converter. When the hot air flow reaches the first flow guide plate 13, the hot air will be effectively blocked and diverted due to the obtuse angle structure formed by the first flow guide plate 13 and the connecting plate 30, and further guided to the heat dissipation port 32 below.

[0051] The height of the second flow guide plate 23 is lower than that of the first flow guide plate 13. The height difference ensures that the second flow guide plate 23 can effectively guide the hot air from the inverter outlet to bypass the inverter air inlet in front, and the hot air can be smoothly guided to the heat dissipation port 32 when it reaches the first flow guide plate 13. Preferably, the height of the second flow guide plate 23 is at least 70 mm lower than that of the first flow guide plate 13. The present application sets the second flow guide plate 23 on the high-voltage installation plate 20, cooperates with the first flow guide plate 13 and reasonable height layout, and constructs an efficient hot air flow guiding system. This system can effectively prevent the hot air from the inverter outlet from flowing back to other inverters, while ensuring that the hot air flow is effectively guided to the heat dissipation port 32 for discharge, thereby significantly improving the heat dissipation environment of the high-voltage area 21, prolonging the service life of the inverter and other high-voltage electrical components, and ensuring the stable operation of the air conditioning system.

[0052] According to the electrical component installation plate provided by the present application, a plurality of assembly holes 33 are arranged at the edge positions of the low-voltage installation plate 10 and / or the high-voltage installation plate 20. The assembly holes 33 are preferably connecting bolt holes. The assembly holes 33 located at the low-voltage installation plate 10 (higher) can be fixed by connecting the vertical columns on the side of the cabinet body. The assembly holes 33 located at the high-voltage installation plate 20 (lower) can be fixed by connecting the bottom plate or back plate of the cabinet body.

[0053] According to the preferred embodiment of the present application, the overall installation plate is preferably made of a 2.5 mm thick galvanized sheet. The thickness of 2.5 mm not only ensures the structural stability of the installation plate when carrying various electrical components, but also effectively resists physical wear and chemical corrosion in the working environment, prolonging the service life. The galvanized layer further enhances the corrosion resistance of the installation plate, reducing the risk of electrical failure caused by rust. The flow guide plate is preferably made of a 1.5 mm thick galvanized sheet. The thinner thickness is beneficial to reduce air resistance and optimize the air flow guiding effect. The flow guide plate is fixed to the installation plate by welding, ensuring the structural strength. The flow guide plate effectively isolates the hot air of the high-voltage area 21 from the low-voltage area 11 by guiding and blocking the air flow, preventing heat pollution and ensuring the stable working environment of the low-voltage components. The insulation groove 22, as a key component for isolating high and low voltage, is preferably made of a 1.5 mm thick iron sheet to ensure its mechanical strength and heat resistance. The iron sheet is tightly combined with the high-voltage installation plate 20 by welding, forming a continuous grounding path, effectively preventing the risk of electric leakage caused by insulation failure, and ensuring the safety of operators and equipment. To further improve the signal insulation performance, a layer of tin paper is laid inside the insulation groove 22. The tin paper has good electrical conductivity and electromagnetic shielding effect, can effectively reflect and absorb electromagnetic waves, reduce the interference of the electromagnetic field of the high-voltage area 21 on the signal lines of the low-voltage area 11, and ensure the accuracy of signal acquisition of the controller and other low-voltage components.
