Heat dissipation type power distribution cabinet

Abstract

The invention discloses a heat dissipation type power distribution cabinet. The cabinet comprises a cabinet body, a water storage cavity is formed in the upper part of the cabinet body; a detection groove is formed in the top end of the cabinet body; and a falling hole communicating with the interior of the water storage cavity is formed in the inner bottom of the detection groove in a penetratingmode. Two symmetrically-arranged conductive plates are fixed to the inner wall of the detection groove, two symmetrically-arranged water pumping mechanisms are arranged in the water storage cavity, diffusion cavities are formed in the two side walls of the cabinet body, and a plurality of communicating pipes communicating with the interiors of the diffusion cavities are inserted into the side walls of the water storage cavity. The heat dissipation type power distribution cabinet has the advantages that by arranging a fan, air in the cabinet body is driven by the fan to be conveyed outwards, external air enters the cabinet body, so that the circulating flow of the air in and out of the cabinet body is realized, the heat exchange between the inside and the outside of the cabinet body is completed, the heat in the cabinet body is quickly diffused outwards along with airflow, and the temperature in the cabinet body is kept stable.

Description

technical field [0001] The invention relates to the technical field of power facilities, in particular to a heat dissipation type distribution cabinet. Background technique [0002] 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; [0003] Due to the relatively concentrated internal components of the power distribution cabinet, more heat will be generated during long-term operation. Therefore, it is necessary to dissipate heat inside the power distribution cabinet. At present, the commonly used heat dissipation is to drive heat exchange through air flow to complete heat dissipation, but In rainy weather, the ventilation channel is vulnerable to the impact of rainwater, causing water to enter the power distribution c...
