Distribution box with cooling and dehumidifying functions

Abstract

The invention discloses a distribution box with cooling and dehumidifying functions. The distribution box comprises a distribution box; a mounting plate is arranged in the distribution box; the inner cavity of the distribution box is divided into a front part and a rear part by the mounting plate; a plurality of electronic components are fixedly mounted on the front surface of the mounting plate; a long hole and a plurality of ventilation holes are formed in the left and right side surfaces of the distribution box; the long hole and the ventilation holes are located in the rear half parts of the left side surface and the right side surface of the distribution box; the long hole is located in the middle of the rear half part of the side surface of the distribution box; the length direction of the long hole is vertically extending downward along the side surface of the distribution box; an air guide pipe and an electric air pump are arranged in the distribution box; the lower end of the air guide pipe is fixedly connected with the bottom face of the distribution box; the air guide pipe is perpendicular to the bottom face of the distribution box; and the electric air pump is fixedly installed on the bottom face of the distribution box. The device has the advantages of being simple and practical in structure and having the dual functions of heat dissipation and dust removal.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a power distribution box with the function of cooling and dehumidifying. Background technique [0002] The distribution box is a commonly used device in power equipment. Generally, there are many electronic components and circuits in the distribution box. During the operation of the distribution box, these electronic components and circuits will continue to emit heat after being powered on. As a result, the temperature in the distribution box rises sharply, and the electronic components and circuits are extremely susceptible to the influence of humid air. High temperature and humidity will seriously affect the working quality and service life of electronic devices.

Problems solved by technology

[0002] The distribution box is a commonly used device in power equipment. Generally, there are many electronic components and circuits in the distribution box. During the operation of the distribution box, these electronic components and circuits will continue to emit heat after being powered on. As a result, the temperature in the distribution box rises sharply, and the electronic components and circuits are extremely susceptible to the influence of humid air. High temperature and humidity will seriously affect the working quality and service life of electronic devices.

[0003] In order to solve the above technical problems, those skilled in the art generally set cooling holes or cooling fins on the distribution box, and reduce the temperature in the distribution box through this passive cooling method, and at the same time use a desiccant to maintain the temperature of the distribution box. The dry environment inside; however, the passive heat dissipation method has a limited cooling effect on the distribution box, and cannot effectively reduce the temperature inside the distribution box in high-temperature weather.
