Description
Technical Field
[0001] This utility model relates to the cabinet of a self-circulating control cabinet. Background Technology
[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Existing control cabinets are usually equipped with ventilation holes and auxiliary cooling fans to dissipate heat inside the cabinet, thereby preventing the temperature inside the control cabinet from becoming too high and affecting the normal operation of the electronic components inside. However, when the control cabinet dissipates heat through ventilation holes and fans, the air inside the control cabinet comes into contact with the outside air. The outside air can easily cause dust, oil, and harmful gases in the outside air to pollute the control cabinet. Therefore, it is necessary to develop a self-circulating control cabinet to solve the above problems. Summary of the Invention
[0003] The purpose of this utility model is to provide a cabinet for a self-circulating control cabinet to solve the problems mentioned in the background art.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] A self-circulating control cabinet includes a base plate, side plates, a top plate, a door, and a back plate. Two side plates are positioned between the base plate and the top plate. The door is hinged to one side of one side plate. The back plate is located on the back of the base plate, side plates, and top plate, and is bolted to all three. The top plate has multiple air vents, and a first air guide is fixedly mounted on its top. The back plate has multiple air inlets, and a second air guide is mounted on one side of each inlet, fixed to the back plate. The first air guide has multiple first air pipes, and the second air guide has multiple second air pipes corresponding to the first air pipes. Each first air pipe and its corresponding second air pipe are connected to a cooling pipe, the middle of which has a helical structure. The back plate has a mounting plate, and the cooling pipes pass between the back plate and the mounting plate. The mounting plate has multiple powerful fans.
[0006] Preferably, the mounting plate has a U-shaped structure, with bent edges on both sides. The mounting plate and the bent edges are an integral structure, and the bent edges are connected to the back plate by bolts. A guide plate is provided between the two side walls of the mounting plate, and the guide plate has multiple guide holes one and guide holes two.
[0007] Preferably, both guide hole one and guide hole two are inclinedly arranged on the guide plate, and guide hole one and guide hole two are symmetrically arranged along the central axis of the guide plate.
[0008] Preferably, a fixing plate is fixedly provided on both sides of the guide plate, and the fixing plate is connected to the inner wall of the mounting plate by bolts.
[0009] Preferably, mounting strips are provided on both sides of the bottom plate and the top plate, and the mounting strips on the side plate and the bottom plate are connected by bolts.
[0010] The beneficial effects of this utility model are as follows: This utility model allows hot air inside the control cabinet to flow into the cooling pipe through the air outlet, the first guide shroud, and the first air supply pipe. Then, the cold air generated by the powerful fan blows onto the cooling pipe, thereby cooling the hot air in the cooling pipe. The cooled air then flows back into the cabinet through the second air supply pipe, the second guide shroud, and the air inlet, thus completing a self-circulation. The whole process ensures that the inside of the control cabinet is cooled while preventing outside air from entering the control cabinet, thus preventing dust, oil, and harmful gases from polluting the inside of the control cabinet.

[0019] See Figures 1 to 6 The cabinet of a self-circulating control cabinet shown includes a base plate 11, side plates 12, a top plate 13, a door 15, and a back plate 19. There are two side plates 12, positioned between the base plate 11 and the top plate 13. The door 15 is hinged to one side of one of the side plates 12. The back plate 19 is located on the back of the base plate 11, side plates 12, and top plate 13, and is bolted to all three. The base plate 11, side plates 12, top plate 13, and back plate 19 form a rectangular cabinet. The door 15 serves as the door to enclose the cabinet. The top plate 13 has multiple air vents 17, and a flow guide shroud 14 is fixedly mounted on the top of the top plate 13. The interior of the flow guide shroud 14 communicates with the interior of the base plate 11 through the air vents 17. The back plate 19 has multiple air inlets 18, and a flow guide is provided on one side of each air inlet 18. The second shroud 23 is fixed to the back plate 19. The interior of the second shroud 23 is connected to the interior of the base plate 11 through the air inlet 18. The first shroud 14 is provided with multiple air supply pipes 20, which are connected to the interior of the first shroud 14. The second shroud 23 is provided with multiple air supply pipes 22 corresponding to the air supply pipes 20, which are connected to the interior of the second shroud 23. Each air supply pipe 20 and its corresponding air supply pipe 22 is connected to a cooling pipe 21. The middle part of the cooling pipe 21 has a spiral tube structure. The back plate 19 is provided with a mounting plate 24. The cooling pipe 21 passes through the back plate 19 and the mounting plate 24. The mounting plate 24 is provided with multiple powerful fans 25. The mounting plate 24 has multiple mounting windows corresponding to the powerful fans 25. The powerful fans 25 are installed in the mounting windows on the mounting plate 24.
[0020] Furthermore, the mounting plate 24 has a U-shaped structure, and both sides of the mounting plate 24 are provided with bent edges 26. The mounting plate 24 and the bent edges 26 are an integrated structure. The bent edges 26 are connected to the back plate 19 by bolts. A guide plate 27 is provided between the two side walls of the mounting plate 24. The guide plate 27 is provided with a plurality of guide holes 1 29 and guide holes 2 30.
[0021] Furthermore, both guide holes 29 and 30 are inclinedly arranged on the guide plate 27. The guide holes 29 and 30 are symmetrically arranged along the central axis of the guide plate 27, and the guide holes 29 and 30 are inclined to both sides respectively. The airflow generated by the powerful fan 25 blows towards the guide plate 27, and the airflow diffuses appropriately to both sides through the guide holes 29 and 30 and blows towards the cooling pipe 21, thereby expanding the coverage of the airflow blowing towards the cooling pipe 21 and ensuring that the airflow can blow to all parts of the cooling pipe 21 to ensure the cooling effect.
[0022] Furthermore, fixing plates 28 are fixedly provided on both sides of the guide plate 27. The fixing plates 28 are connected to the inner wall of the mounting plate 24 by bolts. The guide plate 27 can be stably installed between the two side walls of the mounting plate 24 by means of the fixing plates 28 and bolts.
[0023] Furthermore, mounting strips 16 are provided on both sides of the bottom plate 11 and the top plate 13. The mounting strips 16 on the side plate 12 and the bottom plate 11 are connected by bolts. The side plate 12 can be stably installed between the bottom plate 11 and the top plate 13 through the mounting strips 16 and bolts to form a stable cabinet structure.
[0024] The working principle of this utility model is as follows: When the control cabinet is in use, the electronic components inside the control cabinet generate heat, which in turn heats the air inside the cabinet, generating an upward hot airflow. The hot airflow enters the air guide shroud 14 through the air outlet 17, and then enters the cooling pipe 21 through the air supply pipe 20. The powerful fan 25 is activated, and the powerful fan 25 generates a cold airflow that blows onto the cooling pipe 21, thereby cooling the hot airflow flowing through the cooling pipe 21. The solenoid-shaped cooling pipe 21 lengthens the flow path of the hot airflow, thus extending the cooling path and allowing for more thorough cooling. After cooling, the hot airflow becomes cold airflow. This cold airflow flows into the air guide shroud 23 through the air supply pipe 22, and then into the cabinet through the air inlet 18, thus achieving a self-circulation of hot airflow being discharged and cooled, and then the cooled airflow flowing back into the cabinet. This allows the control cabinet to be continuously cooled while preventing outside air from entering the control cabinet, thus preventing dust, oil, and harmful gases from contaminating the control cabinet.
[0025] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
