Problems solved by technology

[0002] In the power distribution room, a large number of power distribution cabinets are used, and the heat accumulation is serious. Electrical components will generate heat during work. Therefore, in order to ensure a safer working environment, the power of the air conditioning system in the power distribution room is relatively large, and Continuous operation has resulted in very high cooling energy consumption, and after the hot air in the power distribution cabinet is discharged, in order to avoid the loss of indoor cold air, the exhausted hot air can only be neutralized and cooled by cold air. It is also the main cause of higher energy consumption, and the indoor space of the power distribution room is large, so if the cold air is to be evenly distributed, it is necessary to greatly increase the working power

Embodiment 1

[0046]A power distribution cabinet with air supply from the bottom, including a basic structure 1 laid in the machine room, and a cabinet structure 2 installed on the top of the basic structure 1;

[0047] The basic structure 1 includes a keel 101 laid above the ground, and the keel 101 is vertically arranged; the main function of the keel 101 is to bear weight, and the keel 101 adopts a light steel keel, which is light in weight and has sufficient supporting capacity; A plurality of height adjustment mechanisms 3 are installed at the bottom of the 101; through the height adjustment mechanisms 3, the horizontal support for the keel 101 can be completed on uneven ground. The upper end of the keel 101 is welded with a vertical rod 102; between the horizontally adjacent keels 101, a heat insulation cotton 103 is laid, and a floor 104 is laid above the heat insulation cotton 103; the vertical rod 102 Extending upward to the outside of the floor 104, a limit nut 105 is arranged on ...

Embodiment 2

[0053] A box body 4 is assembled at the socket 111; the top of the box body 4 has an outer edge portion 401, and the outer edge portion 401 is limited to the top of the floor 104; the air inlet box 205 is inserted into the box body 4, the bottom of the cabinet 201 acts on the outer part 401; the outer part 401 is sealed between the cabinet 4 and the cabinet 201; the outer surface of the cabinet 4 is provided with a tuyere, An insect-proof net 402 is installed in the tuyere; when the supporting feet 206 are limited to the bottom of the limiting block 106, the distance between the bottom of the cabinet 201 and the floor 104 is greater than the height of the cabinet 4 , at this time the casing 4 is taken out upwards.

[0054] In practical applications, it is inevitable that there will be rodent pests. After adopting the above box body 4, a protection can be formed on the bottom of the air intake box 205, which can prevent the entry of rodents and insects while not affecting the ...

Embodiment 3

[0056] An air inlet cover 5 is threadedly connected at the air inlet hole 204, and the top of the air inlet cover 5 is a plane on which a motor 501 is installed, and the output shaft of the motor 501 extends downward to the In the air inlet box 205; the output shaft of the motor 501 is equipped with a negative pressure fan blade 502; when the negative pressure fan blade 502 rotates, an air inlet negative pressure is formed at the bottom of the air inlet cover 5; On the outer side of the air inlet cover 5 , a plurality of air outlet holes 503 are arranged in a ring above the negative pressure fan blade 502 .

[0057] The negative pressure generated at the bottom of the cabinet by the heat exhaust fan alone is limited, so we adopt the structure of the motor 501 and the negative pressure fan blade 502, which can draw the cold air under the floor into the cabinet 201 to increase the exchange rate .

Abstract

The invention discloses a power distribution cabinet capable of supplying air from the bottom and a heat dissipation method. The power distribution cabinet comprises a base structure laid in a machine room and a cabinet body structure installed at the top of the base structure. The base structure comprises keels laid on the ground, and the keels are longitudinally arranged. The keels are mainly used for bearing load, and the keels are light steel keels which are light in weight and sufficient in supporting capacity. A plurality of height adjusting mechanisms are mounted at the bottoms of the keels; through the height adjusting mechanisms, horizontal supporting of the keels on the uneven ground can be achieved; vertical rods are welded at the upper ends of the keels; and heat insulation cotton is laid between the adjacent keels in the transverse direction. The device can reduce the cold air distribution loss, and enables the cold air to effectively act on each power distribution cabinet.
