Description

Technical Field

[0001] This invention relates to the technical field of electrical control devices used in equipment such as air conditioners, and particularly to an electrical control cabinet and an air conditioning unit. Background Technology

[0002] Electrical control technology is widely used in various structural equipment such as modern heavy industry, water supply systems, central air conditioning, elevator equipment, air conditioning equipment, and vehicle equipment to control the various functional modules within the equipment. Electrical control in these devices is generally achieved through electrical control cabinets. For example, in air conditioning equipment, frequency converters are installed in the electrical control cabinet to achieve frequency conversion control.

[0003] Existing electrical control cabinets have some problems in application, such as:

[0004] Various components need to be housed in electrical control cabinets, but the internal space is limited, making assembly difficult. Expanding the cabinet after assembly is also challenging. Furthermore, maintenance is inconvenient when problems arise. Electrical control cabinets generally need to be protected from water, as water ingress can affect their normal operation and even damage the cabinet or the entire equipment. Meeting waterproofing requirements further reduces the internal space of the control cabinet, exacerbating the aforementioned problems.

[0005] Furthermore, when the structural space inside the electrical control cabinet is limited, the various components are arranged quite densely. However, a significant portion of these components generate heat during operation, sometimes substantial amounts. This places high demands on the cabinet's heat dissipation performance. Inadequate heat dissipation design, leading to poor cooling performance, will affect the operational performance of the components, potentially causing them to malfunction or stop working altogether. Summary of the Invention

[0006] This invention provides an electrical control cabinet and an air conditioning device to solve the technical problems in the prior art, such as the inconvenience of assembling, upgrading, and maintaining electrical control cabinets.

[0013] The cabinet has a second opening and a detachable second cover on its second side. The second cover is used to close the second opening to enable the opening and closing of the second opening.

[0014] The fan is detachably connected to the heat dissipation component, and the connection structure between the fan and the heat dissipation component is located within the opening range of the first opening and / or the second opening.

[0015] The heat dissipation assembly includes an evaporator, which is located in the heat dissipation assembly away from the fan; the evaporator communicates with the first installation space, and the evaporator is used to generate a low pressure at its location, which is lower than the wind pressure at the point in the first installation space where the evaporator communicates.

[0016] The heat dissipation component includes a fan and an evaporator; the fan is adjacent to a first side of the heat dissipation component, and the fan's airflow direction is towards the electronic control component; the evaporator is away from the first side of the heat dissipation component, and the evaporator is in communication with the first mounting space. The evaporator is used to generate a low pressure at its location, which is lower than the wind pressure at the point in the first mounting space in communication with the evaporator.

[0017] The electrical control components include a bearing switching power supply, a heat sink and power device assembly, a multilayer busbar assembly, a circuit breaker assembly, and a reactor assembly. The bearing switching power supply is positioned opposite the fan, and the reactor assembly is positioned opposite the evaporator. The heat sink and power device assembly, the multilayer busbar assembly, and the circuit breaker assembly are arranged sequentially between the bearing switching power supply and the reactor assembly.

[0018] The heat dissipation assembly also includes a water receiving container and a drain connector. The water receiving container is located at the lower end of the evaporator, and one end of the drain connector is connected to the water receiving container, while the other end is located outside the electrical control cabinet.

[0019] The cabinet is a columnar structure with a rectangular cross-section. It includes a top side, a bottom side, and four peripheral sides. The top side is the first side of the cabinet. The cabinet includes a first wall panel, a second wall panel, and a second cover plate. The first wall panel has three sides, each covering one of the three peripheral sides of the cabinet. These three sides are integrally formed by bending sheet metal. The second wall panel covers the bottom side of the cabinet.

[0026] The electrical control cabinet and air conditioning equipment provided by the present invention have the following advantages compared with the prior art:

[0027] The electrical control cabinet provided in this embodiment of the invention has a first opening on a first side of the cabinet body. When the first opening is open, that is, when the first cover is not closed over the first opening, the electrical control components can be moved integrally from the outside of the cabinet body to the first installation space inside the cabinet body, and can also be moved integrally from the first installation space inside the cabinet body to the outside of the cabinet body. Thus, during assembly, various electrical control devices, such as bearing switching power supplies, heat sinks and power device assemblies, circuit breaker assemblies, reactor assemblies, capacitor assemblies, etc., can be assembled into a whole outside the cabinet body to form the electrical control components. Then, with the first opening on the cabinet body open, the electrical control components are integrally installed into the first installation space of the cabinet body through the first opening and fixed. Finally, the first cover is closed over the first opening, achieving closure and sealing, thereby completing the assembly of the electrical control components. In the assembly process described above, the assembly of various electronic control devices into electronic control components is carried out and completed outside the cabinet, rather than within the limited space inside the cabinet. The ample space outside the cabinet allows for easier assembly and higher efficiency. The same beneficial effects are also achieved when the electronic control components need to be moved inside or outside the cabinet for maintenance or upgrades.

[0028] The air conditioning equipment provided by the present invention includes the above-mentioned electrical control cabinet, and naturally has the same technical effects as the above-mentioned electrical control cabinet, which will not be described in detail here. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The embodiments of the electrical control cabinet and air conditioning equipment provided by the present invention will be described below with reference to the accompanying drawings.

[0051] In one embodiment of the electrical control cabinet of the present invention, see [reference needed] Figures 1-9 The electrical control cabinet includes a cabinet body 10, an electrical control component 20, and a heat dissipation component 30. The cabinet body 10 has a first mounting space 11 and a second mounting space 12 arranged side-by-side. The electrical control component 20 is disposed in the first mounting space 11, and the heat dissipation component 30 is disposed in the second mounting space 12. The first side of the cabinet body 10 has a first opening 13 and a removable first cover 14. The first cover 14 is used to close the first opening 13 to allow the first opening 13 to be opened and closed. When the first opening 13 is open, the electrical control component 20 can be moved in and out of the first mounting space 11 along the first opening 13.

[0052] In this embodiment, a first opening 13 is provided on the first side of the cabinet 10. When the first opening 13 is open, that is, when the first cover 14 is not closed on the first opening 13, the electronic control component 20 can be moved integrally from the outside of the cabinet 10 to the first installation space 11 inside the cabinet 10, and can also be moved integrally from the first installation space 11 inside the cabinet 10 to the outside of the cabinet 10, such as... Figure 5 As shown.

[0053] In this embodiment, when assembling the electrical control cabinet, various electrical control components, such as bearing switching power supply 21, heat sink and power device assembly 22, stacked busbar assembly 23, circuit breaker assembly 24, reactor assembly 25, capacitor assembly, etc., can be assembled into a whole outside the cabinet 10 to form electrical control assembly 20. Then, with the first opening 13 on the cabinet 10 in an open state, the electrical control assembly 20 is integrally installed into the first installation space 11 of the cabinet 10 through the first opening 13 and fixed. Finally, the first cover plate 14 is placed over the first opening 13 to close the first opening 13, thereby achieving closure and sealing, and thus completing the assembly of electrical control assembly 20.

[0054] In the above assembly process, the assembly of various electronic control devices into electronic control components 20 is carried out and completed outside the cabinet 10, rather than in the limited space inside the cabinet 10. There is sufficient space outside the cabinet 10 for assembly, which reduces the assembly difficulty and can also achieve higher assembly efficiency.

[0055] Meanwhile, for the electrical control cabinet in this embodiment, when upgrading and repairing the electrical control component 20, the first cover plate 14 can be removed from the cabinet 10 first, opening the first opening 13; then, the electrical control component 20 can be taken out of the cabinet 10 as a whole and moved outside the cabinet 10 through the first opening 13. After moving the electrical control component 20 outside the cabinet 10, there is sufficient space to replace, upgrade, and repair various electrical control devices on the electrical control component 20, making the replacement, upgrade, and repair process more convenient and simple, and helping to achieve higher efficiency. After completing the above tasks, the electrical control component 20 is moved and installed into the first installation space 11 of the cabinet 10 in the aforementioned order, restoring the electrical control cabinet to its original state.

[0056] Specifically, the first side of cabinet 10 can be its upper side; in this case, such as Figure 5 As shown, when assembling the electrical control component 20 into the first installation space 11 of the cabinet 10, the electrical control component 20 can be fixed by hand or by using some devices or tooling to fix the electrical control component 20, and the whole assembly can be moved vertically into the cabinet 10 by hoisting.

[0057] Of course, the first side of the cabinet 10 can also be a side other than the top side. For example, if the cabinet 10 is a columnar structure with a rectangular cross-section, the first side of the cabinet 10 can be one of its left, right, front, or rear sides. In this case, when assembling the electrical control component 20 into the first installation space 11 of the cabinet 10, the electrical control component 20 can be fixed by hand or by using some device or tooling to fix the electrical control component 20, and moved horizontally into the cabinet 10.

[0058] In one embodiment of the electrical control cabinet, the electrical control component 20 is provided with multiple connecting parts for connecting with an external mechanism so that the external mechanism can drive the electrical control component 20 to enter and exit the first installation space 11 through the first opening 13.

[0059] In this embodiment, the connection part facilitates the fixation of the electronic control component 20 by an external mechanism. Furthermore, when moving the electronic control component 20 into the first installation space 11 of the cabinet 10 by hoisting, or moving it from inside the cabinet 10 to outside the cabinet 10, the stability of the electronic control component 20 is higher throughout the entire movement process.

[0060] In one embodiment of the electrical control cabinet, see Figure 7 The first opening is at point 13 (that is, at...) Figure 7 The area (selected by the dashed box in the image) is equipped with a waterproof sponge. When the first cover plate 14 closes at the first opening 13, the waterproof sponge is clamped between the first opening 13 and the first cover plate 14. Specifically, the waterproof sponge is fixed at the first opening 13 by adhesive. Specifically, the waterproof sponge can be made of EVA (ethylene-vinyl acetate copolymer).

[0061] In this embodiment, by providing a waterproof sponge between the first opening 13 and the first cover plate 14, the sealing performance of the first opening 13 and the protection level against water and other components can be improved, thus providing better protection for the electrical control components 20 and the heat dissipation components 30 inside the cabinet 10.

[0062] In this embodiment, the first cover plate 14 can be fixed to the cabinet 10 by screwing. In this way, the first cover plate 14 will be fixed more firmly. Correspondingly, the waterproof sponge can be effectively clamped between the first opening 13 and the first cover plate 14.

[0063] In one embodiment of the electrical control cabinet, the cabinet further includes a junction box 40, which is located on the outside of the cabinet body 10, and the junction box 40 and the electrical control component 20 are respectively located on both sides of the heat dissipation component 30. A wiring area is also provided within the second installation space 12. For example... Figure 10 and Figure 11 As shown, the heat dissipation component 30 has a channel-shaped notch 31, the two ends of which are connected to the inlet box 40 and the electronic control component 20, respectively, for wiring from the inlet box 40 to the electronic control component 20.

[0064] It is understandable that various electrical control devices on the electrical control assembly 20, such as the bearing switching power supply 21, the heat sink and power device assembly 22, the circuit breaker assembly 24, the reactor assembly 25, the capacitor assembly, etc., need to be electrically connected to external power supply devices or other devices in order to input the electrical energy required for operation, or to input and output various signals with other devices.

[0065] In this embodiment, an inlet box 40 is configured to guide some or all of the wiring required for electrical connections into the electrical control cabinet. Furthermore, the inlet box 40 and the electrical control component 20 are respectively positioned on both sides of the heat dissipation component 30, that is, on both sides of the second mounting space 12. In this case, in this embodiment, a dedicated wiring area is configured within the second mounting space 12, through which the wires or signal lines in the inlet box 40 are connected to the electrical control component 20, and connected to various electrical control devices on the electrical control component 20.

[0066] In this embodiment, the wiring area within the second installation space 12 is specifically represented by a notch 31 on the heat dissipation component 30. The two ends of the notch 31 are respectively connected to the inlet box 40 and the electronic control component 20, so that the notch 31 forms a wiring channel, thereby realizing the wiring electrical connection between the inlet box 40 and the electronic control component 20.

[0067] In this embodiment, the necessary structures for electrical connection in the wiring area, such as incoming copper plates or other structures, can be fixed to the wall panel of the heat dissipation assembly 30 adjacent to the wiring area. To achieve this, a structure such as bakelite can be fixed to the wall panel of the heat dissipation assembly 30 adjacent to the wiring area.

[0068] In one embodiment of the electrical control cabinet, see Figure 10 and Figure 11 The second mounting space 12 has a first corner and a second corner in the first lateral direction. A notch 31 is located at the first corner and forms a wiring channel connecting the inlet box 40 and the electrical control assembly 20 in the first corner. The heat dissipation assembly 30 occupies the second corner in the first lateral direction of the second mounting space 12.

[0069] In this embodiment, the shape of the second mounting space 12 can be varied. Here, for the sake of brevity and convenience in description, this embodiment uses a rectangular shape for the second mounting space 12 as an example, with the first side direction as the upper side. In this case, see... Figure 10 and Figure 11 The notch 31 is set at the first corner, and the heat dissipation component 30 occupies the second corner. The shape of the heat dissipation component 30 is semi-convex (no other extra structures occupying a large space are generally set in the second installation space 12 except for the wiring area. Therefore, the heat dissipation component 30 can almost completely occupy the other second installation space 12).

[0070] This arrangement facilitates cable routing within the second installation space 12. Specifically, when the junction box 40 is located on the upper side of the cabinet 10, placing the cable routing area directly opposite the junction box 40 to the wall panel of the cabinet 10 reduces cable length, simplifies wiring difficulty and complexity, and makes the structure more compact. Simultaneously, it allows the heat dissipation component 30 to occupy more space within the second installation space 12, thereby contributing to better heat dissipation.

[0071] In one embodiment of the electrical control cabinet, the heat dissipation assembly includes a fan 32 and an evaporator 24; the fan 32 is adjacent to a first side of the heat dissipation assembly 30, and the airflow direction of the fan 32 is towards the electrical control assembly 20; the evaporator 34 is away from the first side of the heat dissipation assembly 20, and the evaporator 34 communicates with a first mounting space 11. The evaporator 34 is used to generate a low pressure at its location, which is lower than the air pressure at the point of communication between the evaporator 34 and the first mounting space 11. Specifically, in Figure 10 and Figure 11 In the example structure shown, the fan 32 is located on the first side of the heat dissipation assembly 30, that is, the upper side in the figure, and the evaporator 34 can be correspondingly set on the lower side of the heat dissipation assembly 30 shown in the figure.

[0072] In this embodiment, the fan 32 blows air onto the electronic control component 20 located in the first mounting space 11 from the first side; based on the negative pressure generated by the evaporator 34, an airflow is generated at a position away from the first side, from the first mounting space 11 to the location of the evaporator 34 in the second mounting space 12, that is, air is drawn from the first mounting space 11. This forms an airflow circulation 37 between the fan 32, the first mounting space 11, and the evaporator 34. In this airflow circulation 37, the fan 32 blows air onto the electronic control component 20 in the first mounting space 11, and the evaporator 34 draws air from the electronic control component 20 in the first space 11. The combined effect of these two aspects allows the airflow circulation 37 to have a high flow rate and heat exchange efficiency, thereby achieving good heat dissipation for the various electronic control devices of the electronic control component 20 in the first mounting space 11.

[0073] In one embodiment of the electrical control cabinet, a fan 32 is disposed in the area occupied by the heat dissipation assembly 30 at the second corner, and the air outlet direction of the fan 32 is toward the electrical control assembly 20.

[0074] In this embodiment, the fan 32 is positioned at the second corner of the second mounting space 12, and with respect to the heat dissipation assembly 30, the fan 32 is located at the top of the semi-convex structure. The fan 32 faces the electronic control assembly 20 from this position, blowing cool air onto the electronic control assembly 20 to dissipate heat from it.

[0075] In one embodiment of the electrical control cabinet, the second side of the cabinet 10 has a second opening 15 and a removable second cover 16, the second cover 16 being used to close the second opening 15 to enable the opening and closing of the second opening 15.

[0076] In this embodiment, the cabinet 10 is a columnar structure with a rectangular cross-section. The first side is the top side. The first installation space 11 and the second installation space 12 are arranged side by side along the left and right sides inside the cabinet 10 (i.e., the first installation space 11 is located to the left of the second installation space 12 and is adjacent to the left side wall panel of the cabinet 10; the second installation space 12 is located to the right of the first installation space 11 and is adjacent to the right side wall panel of the cabinet 10). Specifically, the second side of the cabinet 10 can be its front side, rear side, or right side.

[0077] In this embodiment, by providing the second opening 15 and the second cover plate 16, when assembling the heat dissipation component 30 into the second mounting space 12, the heat dissipation component 30 can be moved integrally into the second mounting space 12 of the cabinet 10 through the second opening 15, and the heat dissipation component 30 can also be moved integrally from inside the cabinet 10 to outside the cabinet 10. This facilitates the assembly, upgrading, and maintenance of the heat dissipation component 30, which is similar to the electronic control component 20 described above, and will not be repeated here.

[0078] Of course, in this embodiment, the various components of the heat dissipation assembly 30 can also be assembled and installed into the second installation space 12 of the cabinet 10, respectively and in sequence.

[0079] In one embodiment of the electrical control cabinet, the fan 32 is detachably connected to the heat dissipation assembly 30, and the connection structure between the fan 32 and the heat dissipation assembly 30 is disposed within the opening range of the first opening 13 and / or the second opening 15.

[0080] In this embodiment, after the heat dissipation component 30 is installed in the second mounting space 12, when the fan 32 needs to be cleaned, replaced, repaired, or upgraded, the first cover plate 14 or the second cover plate 16 can be removed from the cabinet 10. Then, by dismantling the connection structure between the fan 32 and the heat dissipation component 30, the fan 32 can be removed from the heat dissipation component 30 and moved from inside the cabinet 10 to outside the cabinet 10. This eliminates the need to disassemble the entire heat dissipation component 30 from inside the cabinet 10, making the entire process much simpler. The process of assembling the cooling fan 32 onto the heat dissipation component 30 located in the second mounting space 12 of the cabinet 10 is the reverse of the above and will not be described again.

[0081] For example, in Figure 10 and Figure 11In this configuration, fan 32 is connected and fixed to heat dissipation assembly 30 via mounting bracket 33, which can be a sheet metal part. The mounting bracket 33 and heat dissipation assembly 30 are screwed together, and the screw connection structure is located within the opening range of the first opening 13 and the second opening 15. Figure 10 and Figure 11 In the structure shown, with the first opening 13 and the second opening 15 open, the fan 32 and the mounting part 33 can be removed from the heat dissipation assembly 30 simply by unscrewing the screw connection between the mounting part 33 and the heat dissipation assembly 30. And, the fan 32 and the mounting part 33 can be reassembled onto the heat dissipation assembly 30 simply by tightening the screw connection between the mounting part 33 and the heat dissipation assembly 30.

[0082] In one embodiment of the electrical control cabinet, the electrical control assembly 20 includes a bearing switching power supply 21, a heat sink and power device assembly 22, a multilayer busbar assembly 23, a circuit breaker assembly 24, and a reactor assembly 25. The bearing switching power supply 21 is positioned opposite the fan 32, and the reactor assembly 25 is positioned opposite the evaporator 34. The heat sink and power device assembly 22, the multilayer busbar assembly 23, and the circuit breaker assembly 24 are sequentially arranged between the bearing switching power supply 21 and the reactor assembly 25.

[0083] In this embodiment, the airflow generated by the fan 32 and evaporator 34 of the heat dissipation assembly 30 within the first mounting space 11 first blows towards the bearing switching power supply 21, then sequentially passes through the heat sink and power device assembly 22, the stacked busbar assembly 23, the circuit breaker assembly 24, and finally through the reactor assembly 25. At the reactor assembly 25, the airflow flows towards the evaporator within the second mounting space 12, thus completing the entire airflow cycle. This airflow cycle sequentially flows through multiple electronic control devices on the electronic control assembly 20, achieving heat dissipation for these devices.

[0084] In one embodiment of the electrical control cabinet, the heat dissipation assembly 30 further includes a water receiving container 35 and a drain connector 36. The water receiving container 35 is located at the lower end of the evaporator 34, and one end of the drain connector 36 is connected to the water receiving container 35, while the other end is located outside the electrical control cabinet.

[0085] For the heat dissipation assembly 30, its evaporator 34 will generate condensate during operation. In this embodiment, a water receiving container 35 located below the evaporator 34 can collect the condensate generated by the evaporator 34 and discharge it to the outside of the electrical control cabinet through a drain connector 36. This prevents condensate from accumulating inside the electrical control cabinet, thus preventing the accumulated condensate from affecting the normal operation of the electrical control assembly 20 inside the cabinet or causing damage to various electrical control devices on the electrical control assembly 20.

[0086] In one embodiment of the electrical control cabinet, the cabinet body 10 is a columnar structure with a rectangular cross-section; the cabinet body 10 includes a top side, a bottom side, and four peripheral sides. For example... Figure 1 , Figure 2 and Figure 6 As shown, the first side of the cabinet 10 is the top side. The cabinet 10 includes a first wall panel 17, a second wall panel 18, a first cover plate 14, and a second cover plate 16. Regarding the first cover plate 14 and the second cover plate 16, the first cover plate 14 covers the first side of the cabinet 10, that is, the top side; the second cover plate 16 covers one perimeter of the cabinet 10. Figure 1 The example structure shown is the front side of cabinet 10, and the second cover plate 16 is detachably connected to cabinet 10. The first cover plate 14 and the second cover plate 16 have been described and explained above, and further technical features of the first cover plate 14 and the second cover plate 16 will not be repeated here.

[0087] The first wall panel 17 includes three sides, namely sides 17a, 17b, and 17c, which respectively cover the three perimeters of the cabinet 10. Figure 6 As shown, sides 17a, 17b, and 17c cover the left, rear, and right sides of the cabinet, respectively. Specifically, the three sides 17a, 17b, and 17c of the first wall panel 17 can be a single, integral structure formed by bending sheet metal. The second wall panel 18 covers the bottom side of the cabinet 10.

[0088] Specifically, the first wall panel 17 and the second wall panel 18 are welded together, and the welding method is full welding. This makes the connection between the first wall panel 17 and the second wall panel 18 more secure, and makes the cabinet 10 stronger and provides better physical protection.

[0089] In one embodiment of the electrical control cabinet, at least one edge of the top side of the first wall panel 17 has a folded edge structure 170, which is welded and fixed at the folded seam of the folded edge structure 170, and the welding method is full welding. This can further improve the structural strength of the cabinet 10.

[0090] In one embodiment of the electrical control cabinet, such as Figure 7 As shown, the folding structure 170 folds inward, and then folds the inward-folded portion outward again. This reduces the outward protrusions on the cabinet 10, reduces the geometric space required by the electrical control cabinet, and can also improve or avoid interference between the electrical control cabinet and other external structures.

[0091] like Figure 7As shown, the pleated structure 170 is provided with an outward clearance opening 171, which is located at a position corresponding to the protrusion of the electronic control component 20. Specifically, the protrusion on the electronic control component 20 may be, for example, a refrigerant connector of a radiator, which is generally more prominent than other parts of the electronic control component 20. Therefore, by providing the clearance opening 171 at the corresponding position, collisions between the electronic control component 20 and the pleated structure 170 can be avoided when the electronic control component 20 is moved into the first mounting space 11 inside the cabinet 10, or when it is moved from the first mounting space 11 inside the cabinet 10 to the outside of the cabinet.

[0092] In one embodiment of the electrical control cabinet, the periphery of the cabinet body 10 that is connected and fixed to the second cover plate 16 is the front periphery of the cabinet body 10; the electrical control component 20 is screwed and fixed to the rear periphery of the cabinet body 10. This makes the fixing of the electrical control component 20 within the first installation space 11 of the cabinet body 10 more secure.

[0093] Specifically, a screw hole is provided at the rear of the electrical control component 20, and a window is opened on the rear periphery of the cabinet 10. A mounting component 172 is provided at this window. The mounting component 172 can be a sheet metal part, and it also has screw holes. Figure 2 and Figure 12 As shown, a bolt or similar structure can be passed sequentially through the screw holes on the mounting part 172 and the screw holes at the rear of the electrical control assembly 20 to secure it to the cabinet 10 at the rear.

[0094] For mounting component 172, a bend may be provided at its edge where it meets the window. This bend is nested on the window and can further enhance the strength of the rear periphery of the cabinet 10.

[0095] In one embodiment of the electrical control cabinet, the bottom of the electrical control component 20 is screwed to the cabinet body 10. This arrangement makes the connection and fixation of the electrical control component 20 within the cabinet body 10 more secure.

[0096] Specifically, such as Figure 5 and Figure 7 As shown, the bottom of the electronic control assembly 20 is provided with a bottom fixing hole. Figure 7 As shown in the dashed line, a sheet metal reinforcement 19 is provided on the bottom side of the cabinet 10. The sheet metal reinforcement 19 and the electrical control component 20 are fixed together by bolts screwed to the bottom fixing hole.

[0097] In summary, the electrical control cabinet provided in the above embodiments of the present invention has a first opening 13 on the first side of the cabinet 10. When the first opening 13 is in the open state, that is, when the first cover plate 14 is not closed on the first opening 13, the electrical control component 20 can be moved as a whole from the outside of the cabinet 10 to the first installation space 11 inside the cabinet 10, and can also be moved as a whole from the first installation space 11 inside the cabinet 10 to the outside of the cabinet 10. For the electrical control cabinet, during assembly, various electrical control components, such as bearing switching power supplies, heat sinks and power device assemblies, circuit breaker assemblies, reactor assemblies, and capacitor assemblies, can be assembled into a single unit outside the cabinet 10 to form the electrical control assembly 20. Then, with the first opening 13 on the cabinet 10 open, the electrical control assembly 20 is integrally installed into the first mounting space 11 of the cabinet 10 through the first opening 13 and secured. Finally, the first cover plate 14 is closed over the first opening 13, achieving closure and sealing, thus completing the assembly of the electrical control assembly 20. In this assembly process, the assembly of various electrical control components into the electrical control assembly 20 is performed and completed outside the cabinet 10, rather than within the limited space inside the cabinet 10. Sufficient space outside the cabinet 10 allows for assembly with lower difficulty and higher efficiency. The same beneficial effects are also achieved when the electrical control assembly 20 needs to be moved inside or outside the cabinet 10 for maintenance or upgrades.
