Efficient heat dissipation low-voltage switch cabinet with filter screen convenient to disassemble and assemble

Abstract

The invention belongs to the technical field of low-voltage switch cabinets, and relates to an efficient heat dissipation low-voltage switch cabinet with a filter screen convenient to disassemble and assemble, which comprises a cabinet body, a power distribution cavity is formed in the cabinet body, a through hole is formed in the rear wall of the power distribution cavity, a swing shaft is rotatably arranged on the right wall of the through hole, and a swing frame is fixedly arranged on the periphery of the swing shaft; the front side face of the swing frame is fixedly provided with two dismounting and mounting plates in bilateral symmetry, three filter screens arranged at equal intervals from front to back are slidably arranged in the through hole, two rotating shafts in bilateral symmetry are rotatably arranged on the top face of the cabinet body, rotating plates are fixedly arranged on the peripheries of the two rotating shafts, and limiting cavities are formed in the faces, close to each other, of the two rotating plates. According to the invention, not only is the filter screen convenient to disassemble and assemble, but also the cooling pipes are convenient to disassemble and assemble, the cooling fan can cool the switch cabinet and can cool the cooling pipes, and meanwhile, the cooling pipes can dissipate heat and cool through the cooling fins, so that the cooling efficiency of the switch cabinet is improved, and the service life of the switch cabinet is prolonged. Therefore, the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage switchgear, in particular to a high-efficiency heat-dissipating low-voltage switchgear for easy disassembly and assembly of filter screens. Background technique [0002] Low-voltage switchgear is a kind of electrical equipment. It is usually necessary to open a through hole on the cabinet body to dissipate heat. At the same time, it is necessary to install a filter screen at the through hole to prevent objects from entering the switch cabinet. However, the existing filter screen is generally screwed It is fixed on the switch cabinet, so it takes a lot of time to disassemble the screws when replacing the filter screen, which is extremely inconvenient, and the dust on the filter screen continues to accumulate, which reduces the heat dissipation efficiency of the switch cabinet and the heat dissipation speed is slow, resulting in the temperature inside the switch cabinet. The reduction will affec...

[0002] Low-voltage switchgear is a kind of electrical equipment. It is usually necessary to open a through hole on the cabinet body to dissipate heat. At the same time, it is necessary to install a filter screen at the through hole to prevent objects from entering the switch cabinet. However, the existing filter screen is generally screwed It is fixed on the switch cabinet, so it takes a lot of time to disassemble the screws when replacing the filter screen, which is extremely inconvenient, and the dust on the filter screen continues to accumulate, which reduces the heat dissipation efficiency of the switch cabinet and the heat dissipation speed is slow, resulting in the temperature inside the switch cabinet. Reduced, thus affecting the operation of electrical equipment in the switchgear, and may even cause a fire in the switchgear, and using coolant to continuously cool the switchgear will not only cause waste of resources and waste water pollution, but also increase cooling costs
