Abstract

This utility model relates to an electrical cabinet and its guide rail assembly, including a vertically arranged first support column, a vertically arranged second support column, and multiple horizontal guide rails. The first support column has a first ventilation channel inside, and each guide rail has a second ventilation channel running through it along its length. The second support column has a third ventilation channel. One end of the first ventilation channel has an air inlet structure, and one end of the third ventilation channel has an air outlet structure. Both ends of the guide rails are connected to the first and second support columns, respectively, and both ends of the second ventilation channels are connected to the first and third ventilation channels. Since the electrical components are mounted on the guide rails, the heat generated can be quickly transferred to the guide rails.

The airflow carries away the heat from the guide rail assembly, thereby dissipating heat from the electrical components.

Description

Technical Field

[0001] This utility model belongs to the field of electrical cabinets, and in particular to an electrical cabinet and its guide rail assembly. Background Technology

[0002] Electrical cabinets typically house various electrical components, such as circuit breakers, disconnect switches, voltmeters, ammeters, relays, and PLCs. These components are usually mounted via DIN rails. Specifically, the DIN rails are first installed inside the electrical cabinet, and then each electrical component is mounted onto the DIN rails using screws. This process is convenient, the positions of the electrical components are adjustable, facilitating future modifications, and allows for an orderly and compact arrangement of the components.

[0003] Electrical components generate heat during operation, so electrical cabinets typically require cooling systems such as fans or heat pipes. However, if outside air is directly vented into the cabinet using fans, dust and water vapor carried in the air can easily affect the performance and lifespan of the electrical components. While various types of guide rails exist, none offer auxiliary heat dissipation capabilities. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an electrical cabinet and its guide rail assembly, which, in conjunction with a fan, can play a role in auxiliary heat dissipation.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a guide rail assembly, including a vertically arranged first support column, a vertically arranged second support column, and multiple horizontal guide rails. The first support column has a first ventilation channel inside, and each guide rail has a second ventilation channel that runs through the guide rail along its length. The second support column has a third ventilation channel inside. One end of the first ventilation channel has an air inlet structure, and one end of the third ventilation channel has an air outlet structure. The two ends of the guide rail are respectively connected to the first support column and the second support column, and the two ends of the second ventilation channel are respectively connected to the first ventilation channel and the third ventilation channel.

[0006] Furthermore, the air inlet structure is an air inlet pipe detachably connected to the first support column, and the air outlet structure is an air outlet pipe detachably connected to the second support column.

[0007] Furthermore, the guide rail has an H-shaped cross-section, and the first and second support columns include a main body with a U-shaped cross-section. A connecting plate is provided on the outer wall of the open part of the main body, and mounting holes are provided on the connecting plate.

[0008] Furthermore, a sealing gasket is provided on the connecting plate.

[0009] Furthermore, the first support column, the second support column, and the guide rail are made of aluminum or steel.

[0010] An electrical cabinet includes a fan and a cabinet body, wherein the aforementioned guide rail assembly is installed inside the cabinet body, and the fan is connected to an air intake structure.

[0011] Furthermore, the air inlet structure is an air inlet pipe detachably connected to the first support column, and the air outlet structure is an air outlet pipe detachably connected to the second support column. Both the air inlet pipe and the air outlet pipe penetrate the cabinet, and the air inlet pipe is connected to the fan.

[0012] The beneficial effects of this utility model are: since the electrical components are installed on the guide rail, the heat generated can be quickly transferred to the guide rail. This utility model sets up a network of ventilation channels inside the guide rail assembly, and a fan can be used to transport external cold air into the ventilation network. When the air circulates, it can carry away the heat of the guide rail assembly, thereby dissipating heat from the electrical components.

[0013] In this invention, air flows in an independent ventilation channel and will not enter the installation space of electrical components. This prevents dust, moisture and other impurities in the outside air from entering the electrical cabinet and affecting the performance or service life of the electrical components.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] The guide rail assembly of this utility model, such as Figure 1 As shown, it includes a vertically arranged first support column 1, a vertically arranged second support column 2, and multiple horizontal guide rails 3. The first support column 1 has a first ventilation channel 4 inside. Each guide rail 3 has a second ventilation channel 5 that runs through the guide rail 3 along its length. The second support column 2 has a third ventilation channel 6 inside. One end of the first ventilation channel 4 has an air inlet structure 7, and one end of the third ventilation channel 6 has an air outlet structure 8. The two ends of the guide rail 3 are connected to the first support column 1 and the second support column 2, respectively, and the two ends of the second ventilation channel 5 are connected to the first ventilation channel 4 and the third ventilation channel 6, respectively.

[0027] The first support column 1 and the second support column 2 support the guide rail 3, which is used to install various electrical components. By setting multiple guide rails 3, each guide rail 3 can be used to install multiple electrical components, enabling the electrical components to be installed in rows, thus facilitating the orderly installation of electrical components into the electrical cabinet. The two ends of the guide rail 3 can be welded to the first support column 1 and the second support column 2, or they can be connected using screws or other connectors.

[0028] The first ventilation channel 4, the second ventilation channel 5, and the third ventilation channel 6 form an independent ventilation channel network. This ventilation channel network has an air inlet and an air outlet and is not connected to the space where electrical components are installed in the electrical cabinet. When external cold air circulates in this ventilation channel network, it will not directly contact the electrical components, thereby preventing dust, moisture, etc. in the air from adhering to the electrical components and affecting their performance and service life.

[0029] The auxiliary heat dissipation process of this utility model is as follows: the guide rail 3 is made of a material with a high thermal conductivity. Since the electrical components are installed on the guide rail 3, the heat generated by the electrical components can be directly transferred to the guide rail 3. The external cold air is transported to the first ventilation channel 4 through the air intake structure 7. The cold air can then enter the second ventilation channel 5 inside each guide rail 3, taking away the heat of the guide rail 3, thereby dissipating heat from the electrical components. After the cold air flows through each second ventilation channel 5, it gathers in the third ventilation channel 6 and is discharged to the external space of the electrical cabinet through the air outlet structure 8.

[0030] The electrical cabinet of this utility model, such as Figure 2 As shown, it includes a fan 200 and a cabinet 100, with the cabinet 100 containing... Figure 1 The guide rail assembly shown has the fan 200 connected to the air intake structure 7. Specifically, the cabinet 100 is a cuboid cavity formed by a top plate, bottom plate, left side plate, right side plate, back plate, and cabinet door. The first support column 1 and the second support column 2 can be installed on the left and right edges of the back plate, or on the left and right side plates respectively. The guide rail 3 is located on the side wall of the back plate. The fan 200 is used to continuously deliver cool outside air into the first ventilation channel 4 to dissipate heat from the electrical components; the fan 200 can be made using existing technology.

[0031] The first ventilation channel 4 extends to one end face of the first support column 1, and the air inlet structure 7 is the opening of the first ventilation channel 4. The third ventilation channel 6 extends to one end face of the second support column 2, and the air outlet structure 8 is the opening of the third ventilation channel 6. However, since the air inlet structure 7 and the air outlet structure 8 need to connect the internal and external spaces of the cabinet 100, in order to facilitate the installation of the guide rail assembly into the cabinet 100, in this utility model, the air inlet structure 7 is an air inlet pipe detachably connected to the first support column 1, and the air outlet structure 8 is an air outlet pipe detachably connected to the second support column 2. During installation, the first support column 1, the second support column 2, and the guide rail 3 are first installed as a whole into the cabinet 100. Then, through holes are opened on the cabinet 100, and the air inlet pipe and the air outlet pipe are passed through the through holes and connected to the first support column 1 and the second support column 2 respectively. The air inlet pipe can be threaded to the first support column 1, and the air outlet pipe can be threaded to the second support column 2. The air inlet pipe and the air outlet pipe can be metal pipes, plastic pipes, or various flexible hoses. Fan 200 is connected to the air inlet duct and can be installed on the outer wall of cabinet 100.

[0032] The first ventilation channel 4, the second ventilation channel 5, and the third ventilation channel 6 can be various shapes such as circular channels and rectangular channels. The cross-sections of the first support column 1, the second support column 2, and the guide rail 3 can also be of various shapes. For example, one feasible implementation of the guide rail 3 is as follows: Figure 3As shown, the guide rail 3 has an H-shaped cross-section, consisting of two parallel horizontal plates and a partition perpendicular to the horizontal plates. One side of the partition serves as the second ventilation channel 5, while the other side is used for mounting electrical components. When this shape of guide rail 3 is used, the guide rail 3 and the back panel of the cabinet 100 form an independent second ventilation channel 5, as shown... Figure 4 As shown. Similarly, the cross-sections of the first support column 1 and the second support column 2 can be as follows. Figure 5 As shown, each component includes a main body with a U-shaped cross-section. A connecting plate 9 is provided on the outer wall of the open portion of the main body, and mounting holes 10 are provided on the connecting plate 9. When installing the first support column 1 and the second support column 2, the U-shaped main body and the side wall of the cabinet 100 form a first ventilation channel 4 and a third ventilation channel 6. The first support column 1 and the second support column 2 are fixedly installed by passing screws through the mounting holes 10 and threading them into the cabinet 100. To ensure airtightness and prevent air leakage from the first ventilation channel 4, the second ventilation channel 5, and the third ventilation channel 6 into the space where electrical components are installed, a sealing gasket 11 is provided on the connecting plate 9. The sealing gasket 11 is located between the connecting plate 9 and the side wall of the cabinet 100. Similarly, a sealing gasket 11 can also be provided between the guide rail 3 and the back panel of the cabinet 100.

[0033] Another feasible implementation of guide rail 3 is as follows: Figure 7 As shown, the guide rail 3 includes a rectangular annular heat dissipation section. Mounting plates are provided at the top and bottom of one side of the heat dissipation section. The two mounting plates and the side wall of the heat dissipation section form a recessed mounting space, in which electrical components can be installed. The guide rail 3 mates with the cabinet 100 as follows: Figure 8 As shown. Similarly, the cross-sections of the first support column 1 and the second support column 2 can be as follows. Figure 9 As shown, a rectangular ring-shaped column is used, and one side wall of the column is directly installed to the cabinet 100 with screws, as shown. Figure 10 As shown.

[0034] In this invention, the first support column 1, the second support column 2, and the guide rail 3 are made of aluminum or steel, which have high strength and excellent thermal conductivity, thus facilitating rapid heat dissipation.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
