An indoor distribution box with good cooling effect

Abstract

The invention belongs to the technical field of electrical equipment, and discloses an indoor distribution box with a high heat dissipation effect; the indoor distribution box is characterized by comprising a box body, a box door and an electrical element, and further comprising a partition plate and a heat conduction plate which are arranged in the box body, wherein the partition plate and the heat conduction plate are parallel to the box door; the partition plate is located between the heat conduction plate and the box door; a containing cavity is formed between the partition plate and the box door; a heat exchange cavity is formed between the partition plate and the heat conduction plate; a heat dissipation cavity is formed between the heat conduction plate and the back side of the boxbody; two heat exchange holes are formed in the partition plate, and a heat exchange fan is arranged at the position of at least one heat exchange hole; an air inlet and an air outlet are formed in the box body, and the air inlet and the air outlet are both communicated with the heat dissipation cavity; a heat dissipation fan is arranged in the heat dissipation cavity; and a driving motor used fordriving the heat exchange fan and the heat dissipation fan to rotate is further arranged on the box body. The indoor distribution box has the advantage that external air cannot be guided into the distribution box, and the heat of the distribution box can be effectively dissipated, so that an effect of preventing dust from entering the distribution box is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an indoor distribution box with good heat dissipation effect. Background technique [0002] The power distribution box is the final equipment of the power distribution system. It is used in the occasions where the load is scattered and the circuit is small. It is used to distribute the electric energy of a certain circuit of the upper power distribution equipment to the nearby load. There are various electrical components inside the distribution box, which will generate a lot of heat during the working process. When the heat accumulates too much, it is not conducive to the operation of the distribution box and will also affect the performance of the distribution box. If you only rely on the heat exchange between the distribution box itself and the outside world, due to the small air flow in the distribution box, the heat dissipation efficiency is extremely low, and t...

Problems solved by technology

But in actual use, dust will quickly accumulate on the filter and block the filter after a period of time

In order to ensure that the air pump can smoothly deliver low-temperature air into the box, frequent cleaning or replacement of the filter screen is required, which is inconvenient to operate
