Abstract

The invention discloses a distribution box comprising a heat dissipation box body, an exhaust box body, a distribution box body and a distribution box door. A transverse partition plate is arranged inthe distribution box body, a plurality of first air inlet holes and a plurality of first air outlet holes are arranged in the distribution box body, a plurality of second air inlet holes are arrangedin the heat dissipation box body, and the first air outlet is communicated with the corresponding second air inlet hole; a third air inlet hole and a third air outlet hole are arranged in the exhaustbox body, a waterproof fan is arranged in the exhaust box body, a second air outlet hole is arranged in the heat dissipation box body, and the second air outlet hole is communicated with the third air inlet hole; an upper air inlet hole communicated with the upper air cavity and an upper air outlet hole communicated with the upper air cavity are arranged in the distribution box body, and a middlehole communicated with the upper air outlet hole is arranged in the heat dissipation box body. The distribution box has the beneficial effects that: a plurality of conventional electrical equipment can be accommodated, structural protection and overheating protection are carried out on the internal electrical equipment, the continuous heat dissipation capacity is achieved, and the heat dissipation effect is good.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a distribution box. Background technique [0002] The distribution box is a common electrical assembly in life. The distribution box can assemble various electrical equipment and electrical components such as switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet. The circuit can be turned on or off by means of a manual or automatic switch. Since the distribution box may be equipped with various electrical equipment, it will continue to generate heat when it is working. In relatively high-temperature areas or environments outdoors, especially for distribution boxes that are equipped with electrical equipment that is not suitable for long-term high-temperature environments As far as the electric box is concerned, heat dissipation is the top priority. However, the current distribution box ...
