Power distribution cabinet with good heat dissipation effect

Abstract

The invention discloses a power distribution cabinet with a good heat dissipation effect. The cabinet comprises a cabinet body; the bottom of the cabinet body is fixedly connected with a motor throughscrews; a rotating shaft is welded to an output shaft of the motor; a first plate body is welded on the outer side wall of the rotating shaft; the rotating shaft penetrates through the first plate body and is fixedly connected with three fan blades; second plate bodies are fixedly connected to the two sides of the bottom of the first plate body; the motor, the rotating shaft and a sleeve are matched with one another, so that the first plate body drives the second plate body, a frame body and the plurality of single fan blades to rotate; an inverted conical design is formed between the two second plate bodies, so that air flows spirally from bottom to top, and therefore, the air in the cabinet body can be dissipated towards two sides, and meanwhile, under the driving of the motor, the three fan blades rotate at the top of power distribution equipment, a wind direction is diffused, and the outward flowing of hot air is accelerated under the influence of the spiral airflow, so that thehot air of the power distribution equipment is high in flowability and rapid to diffuse, and is discharged from filter screens on the two sides.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with good heat dissipation effect. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. China's publicly authorized invention: Lo...

Problems solved by technology

This level of equipment should provide protection, monitoring and control for the load. China's publicly authorized invention: Low-voltage power distribution with ventilation and heat dissipation (application number: CN201620956973.7) discloses a low-voltage power distribution cabinet with ventilation and heat dissipation, including low-voltage power distribution The side screen of the electric cabinet, the side screen of the low-voltage power distribution cabinet is provided with ventilation and heat dissipation holes, and the side screen of the low-voltage power distribution cabinet is provided with a movable and adjustable sealing plate corresponding to the ventilation and heat dissipation holes. Open or close the ventilation holes to improve the heat dissipation effect of the low-voltage power distribution cabinet, but the heat dissipation effect is low, and the internal equipment of the power distribution cabinet is always in the working state, and the temperature in the power distribution cabinet gradually rises, which cannot guarantee timely To turn on the heat dissipation is more troublesome and laborious. Therefore, a power distribution cabinet with good heat dissipation effect is proposed
