Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and in particular to a fireproof switch cabinet with high heat dissipation efficiency. Background Technology

[0002] High-voltage switchgear generates high temperatures during operation, requiring a cooling system to dissipate heat from its interior.

[0003] According to the patent document with publication number CN222802379U, a chilled water circulator cools water and delivers it to the interior of the cooling coil through an inlet pipe. During this process, the interior of the duct is cooled. As the fan delivers airflow from the outside to the high-voltage switchgear, it passes through the duct. The cooling water inside the duct, in conjunction with the cooling coil, cools the airflow, allowing for sufficient contact between the airflow and the cooling coil. The cooled airflow then enters the interior of the high-voltage switchgear, effectively cooling the internal components and providing high-efficiency cooling. In this patent, a dust filter is fixedly installed on one side of the fan to protect the cooling coil from dust. However, over time, dust accumulates on the filter. If it cannot be removed for cleaning, it reduces airflow and thus affects heat dissipation. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a fireproof switch cabinet with high heat dissipation efficiency, which solves the problem that the dustproof screen of the existing switch cabinet cannot be disassembled and cleaned.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fireproof switch cabinet with high heat dissipation efficiency, including a cabinet body. Multiple air ducts are equidistantly installed on one outer surface of the cabinet body along a vertical direction. A fan is installed inside each air duct. A dustproof net is detachably installed on the outer side of each air duct. Multiple grooves are equidistantly formed along the circumferential direction at the edge of the outer surface of the dustproof net. A telescopic rod is installed in each groove, and the telescopic rod is telescopically connected to the groove. When its telescopic end is extended, it is inserted into the air duct, thus enabling the detachable connection of the dustproof net. A drive assembly, which is an elastic mechanism, is sleeved on the telescopic rod. One end of the drive assembly is fixedly connected to the inner wall of the groove, and the other end is fixedly sleeved on the outside of the telescopic end of the telescopic rod. The drive assembly is used to drive the telescopic rod to retract and extend, realizing the connection and separation of the telescopic rod and the air duct.

[0006] Preferably, the drive assembly includes a movable plate fixedly sleeved outside the telescopic end of the telescopic rod. A spring is sleeved outside the telescopic rod, one end of which is fixed to the inner wall of the groove and the other end is fixed to the movable plate. A sliding handle is horizontally and vertically fixedly connected to the front outer surface of the movable plate, and the sliding handle is slidably mounted on the dustproof net.

[0007] Preferably, a groove is formed on the outer surface of the dustproof net corresponding to the sliding handle, the groove and the recess are interconnected, and the sliding handle is slidably disposed in the groove.

[0008] Preferably, a slot is provided on the inner surface of the duct corresponding to the telescopic rod, and the telescopic rod is inserted into the slot.

[0009] Preferably, a first cooling coil and a second cooling coil are installed inside the air duct. The bottoms of the first cooling coil and the second cooling coil are connected. The top of the first cooling coil is connected to a water inlet pipe, and the top of the second cooling coil is connected to a water return pipe. A chilled water circulator is fixedly installed on the top of the cabinet. The output end of the chilled water circulator is connected to the water inlet pipe, and the water return pipe is connected to the input end of the chilled water circulator.

[0010] Preferably, the outer sides of the first cooling coil and the second cooling coil are provided with shields, the shields are fixed to the cabinet, and the inner walls of the shields are equipped with heat insulation pads.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] This device uses a telescopic rod and a drive assembly. Pulling the drive assembly allows the telescopic rod to be inserted into or detached from the slot, thus enabling the connection and separation of the dustproof net from the air duct. This makes the dustproof net a detachable mechanism, facilitating its removal for cleaning. Attached Figure Description

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a fireproof switch cabinet with high heat dissipation efficiency, including a cabinet body 1. Multiple air ducts 4 are equidistantly installed vertically on one outer surface of the cabinet body 1. A fan 5 is installed inside each air duct 4. A dustproof net 6 is detachably installed on the outer side of each air duct 4. Multiple grooves 7 are equidistantly formed along the circumferential direction at the edge of the outer surface of the dustproof net 6. A telescopic rod 8 is installed in each groove 7. The telescopic rod 8 is telescopically connected to the groove 7, and its extended end is inserted into the air duct 4 to achieve detachable connection of the dustproof net 6. A drive assembly 9 is an elastic mechanism that is sleeved on the telescopic rod 8. One end of the drive assembly 9 is fixedly connected to the inner wall of the groove 7, and the other end is fixedly sleeved on the outside of the telescopic end of the telescopic rod 8. The drive assembly 9 is used to drive the telescopic rod 8 to retract and extend, realizing the connection and separation of the telescopic rod 8 and the air duct 4.

[0022] The drive assembly 9 includes a movable plate 901 fixedly sleeved on the outside of the telescopic end of the telescopic rod 8. A spring 902 is sleeved on the outside of the telescopic rod 8. One end of the spring 902 is fixed to the inner wall of the groove 7, and the other end is fixed to the movable plate 901. A sliding handle 903 is horizontally and vertically fixedly connected to the front outer surface of the movable plate 901. The sliding handle 903 is slidably mounted on the dustproof net 6.

[0023] A groove 904 is provided on the outer surface of the dustproof net 6 at a position corresponding to the sliding handle 903. The groove 904 and the groove 7 are interconnected, and the sliding handle 903 is slidably disposed in the groove 904.

[0024] A slot 801 is provided on the inner surface of the duct 4 at a position corresponding to the telescopic rod 8, and the telescopic rod 8 is inserted into the slot 801.

[0025] In this embodiment, pulling the sliding handle 903 causes it to slide within the groove 904, moving the moving plate 901. The moving plate 901 then causes the telescopic rod 8 to retract or extend, simultaneously compressing or extending the spring 902. When the moving plate 901 retracts the telescopic rod 8, it disengages from the slot 801, at which point the dustproof net 6 is in an active state and can be removed. When installing the dustproof net 6, first pull the sliding handle 903 to fully retract the telescopic rod 8 into the groove 7. Then align the telescopic rod 8 with the slot 801, place the dustproof net 6, and release the sliding handle 903. Under the action of the spring 902, the telescopic rod 8 inserts into the slot 801, connecting the dustproof net 6 and the duct 4.

[0026] This embodiment allows for the disassembly and installation of the dustproof net 6. By using the telescopic rod 8 and the drive component 9, pulling the drive component 9 can cause the telescopic rod 8 to be inserted into or disengaged from the slot 801, thereby enabling the connection and separation of the dustproof net 6 from the air duct 4. This makes the dustproof net 6 a detachable mechanism, facilitating its removal for cleaning.

[0027] Example 2

[0028] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 4 , Figure 5 As shown, to further better realize this utility model, the following arrangement is specifically adopted: In this embodiment, a first cooling coil 11 and a second cooling coil 12 are installed inside the air duct 4. The bottoms of the first cooling coil 11 and the second cooling coil 12 are connected. The top of the first cooling coil 11 is connected to the water inlet pipe 10, and the top of the second cooling coil 12 is connected to the water return pipe. A chilled water circulator 2 is fixedly installed on the top of the cabinet 1. The output end of the chilled water circulator 2 is connected to the water inlet pipe 10, and the water return pipe is connected to the input end of the chilled water circulator 2.

[0029] A shield 3 is provided on the outside of the first cooling coil 11 and the second cooling coil 12. The shield 3 is fixed on the cabinet 1, and an insulation pad is installed on the inner wall of the shield 3.

[0030] In this embodiment, the shield 3 can protect the cooling coil from external objects. By setting the insulation pad, the cooling water inside the cooling coil can be kept warm, preventing the water temperature inside the cooling coil from losing too quickly and improving the temperature retention effect of the cooling coil. During heat dissipation, the fan 5 and the cooling water circulator are started. The cooling water circulator 2 cools the water and delivers it to the inside of the cooling coil through the water inlet pipe 10. At this time, the inside of the air duct 4 is cooled. When the fan 5 delivers the external airflow to the inside of the switch cabinet, it will pass through the air duct 4. The cooling water inside the air duct 4, together with the cooling coil, will cool the airflow. The airflow can fully contact the cooling coil. The cooled airflow enters the inside of the switch cabinet. The cold airflow can cool the components inside the switch cabinet, thus achieving the advantage of efficient cooling and preventing the temperature inside the switch cabinet from becoming too high, which could lead to a fire.
