Closed type multi-heat-dissipation distribution box

Abstract

The invention discloses a closed type multi-heat-dissipation distribution box. The closed type multi-heat-dissipation distribution box comprises a horizontally-arranged heat dissipation base; a supporting mounting cylinder is vertically arranged at the upper end of the heat dissipation base; the outer side of the supporting mounting cylinder is uniformly covered with corrugated heat dissipation plates; power distribution mounting plates are vertically arranged in the supporting mounting cylinder at equal intervals through flow-guiding mounting columns which are arranged in a front-back symmetrical and uniform mode; a liquid storage box is horizontally inlaid in the interior of the left half section of the heat dissipation base; a liquid conveying power cavity is inlaid in the middle position, matched with the right side of the liquid storage box, of the heat dissipation base; the upper left corner of the liquid conveying power cavity is connected with the right lower corner of the liquid storage box through a pumping pipe; a liquid conveying pump is inlaid at the left end, matched with the liquid storage box, of the pumping pipe; and an electromagnetic valve is arranged at the right end, matched with the liquid conveying power cavity, of the pumping pipe. The closed type multi-heat-dissipation distribution box has the advantages of compact structural design, a full-closed structure, direct contact type heat dissipation, comprehensive heat dissipation, long-time operation and the like.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a closed multiple heat dissipation distribution box. Background technique [0002] The distribution box 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 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. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control for the loads. The stable operation of the distribution box determines the efficiency and safety of the operation, but the currently used There are many problems with the distribution box. [0003] In order to solve the above problems, ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention is proposed, which overcomes the problems of the currently used power distribution device, due to the use of a semi-open structure, which causes serious dust accumulation, affects the normal operation of the equipment, and even short-circuits. Due to the air-guiding structure, the heat dissipation speed is slow, the heat accumulation is obvious after long-term use, the circuit board is deformed, the life is short, and there are safety hazards, etc., so that the present invention has a compact structure design, a completely closed structure, and direct contact heat dissipation , comprehensive heat dissipation, can run for a long time and so on
