A self-ventilating heat exchange type power distribution cabinet

Abstract

The invention discloses an autonomously ventilated and heat-exchanging power distribution cabinet, which belongs to the technical field of power distribution cabinets. By adding an inner ventilation cover and an outer dust-proof board to the left and right vents of the cabinet body, when the cabinet body is in a normal low-temperature environment, , a pair of outer dust-proof boards are sealed and connected to the vent to prevent dust and water vapor. When the cabinet is in a high-temperature environment, the multiple memory deformation rods connected to the flexible magnetic isolation sheet return to their spring phase state, and pull the flexible magnetic isolation sheet to flip outwards. When the inner magnetic sheet is slowly exposed, at this time, because the inner magnetic sheet acts as a magnetic repulsion to the outer magnetic sheet, the outer dust-proof plate moves outward. After the outer dust-proof board is separated from the vent, the elastic dust-proof cloth connected between the outer dust-proof board and the positioning frame is exposed. At this time, the air outside the cabinet is introduced into the cabinet through the elastic dust-proof cloth to realize the realization according to the environment inside the cabinet. Independent ventilation and heat exchange, and at the same time, with the help of the cooling fan, the ventilation and heat dissipation effect is further improved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, and more specifically relates to a self-ventilating and heat-exchanging power distribution cabinet. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is used in the occasions where the load is relatively scattered and the circuit is small. It distributes the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. Because there are many electrical components inside the power distribution cabinet, it will generate a lot of heat when it is working. When the heat accumulates too much, it is not conducive to the normal operation of the power distribution cabinet. [0003] In the prior art, in order to prevent a large amount of heat stored in the cabinet from dissipating, a cooling fan is generally installed at the vent on the end wall...

Problems solved by technology

Because there are many electrical components inside the power distribution cabinet, it will generate a lot of heat when it is working. When the heat accumulates too much, it is not conducive to the normal operation of the power distribution cabinet.

[0003] In the prior art, in order to prevent a large amount of heat stored in the cabinet from dissipating, a cooling fan is generally installed at the vent on the end wall of the cabinet to dissipate heat. Although it plays the role of air flow, it is difficult to remove the dust in the outside air. Interception, and in low temperature environment, due to the vents make the inside of the cabinet and the outside still maintain a certain air circulation effect, so in the case of long-term use, there will still be a lot of dust inside the cabinet, and at the same time, the water vapor from the outside will also enter the cabinet , is not conducive to the safe use of electrical components
