Power distribution box with heat dissipation function

Abstract

The present invention discloses a power distribution box with a heat dissipation function. The power distribution box comprises an outer box body; two groups of first ventilation holes which are symmetrical to each other are formed at the outer surface of the outer box body; a dust screen is fixedly connected into each first ventilation hole; the inner top wall of the outer box body is fixedly connected with a heat dissipation fan; the inner side wall of the outer box body is fixedly connected with two groups of symmetrical springs; the inner bottom wall of the outer box body is fixedly connected with an inner box body; second ventilation holes are formed at the top of the inner box body; two symmetrical notches are formed at the outer side surface of the inner box body; and the upper part of the inner side wall of the inner box body is fixedly connected with a first temperature sensor and a second temperature sensor. With the technical schemes of the invention adopted, the power distribution box can be effectively prevented from being damaged, the convection speed of air is effectively speeded up, the timely discharge of heat is ensured, and the problems of low heat dissipation efficiency and low practical performance can be solved. The power distribution box with the heat dissipation function has the advantages of more diverse heat dissipation measures, high safety performance, good heat dissipation effect and higher precision.

Description

Technical field [0001] The invention relates to the technical field of power distribution boxes, in particular to a power distribution box with heat dissipation function. Background technique [0002] The distribution box is divided into power distribution box, lighting distribution box and metering box. It is the final equipment of the power distribution system. The distribution box is the general name of the motor control center. The distribution box is used in the case where the load is relatively scattered and the circuit is less. On occasion, they distribute the electric energy of a circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control of the load. The distribution box has a reasonable distribution of electric energy to facilitate the opening and closing operations of the circuit. It has a high level of safety protection and can visually display the conduction state of the circuit...
