Description
Technical Field
[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a multifunctional power distribution cabinet which is convenient for heat dissipation. Background Art
[0002] The power distribution cabinet, also known as the distribution box, is a commonly used power distribution cabinet, lighting distribution cabinet, and metering cabinet. It is the final equipment of the power distribution system. Because it generates a lot of heat when it is working, it often causes failures, so it needs to be cooled in time. When the power distribution cabinet in the prior art dissipates heat, it usually opens a heat dissipation port on the side wall of the cabinet to take away the heat generated by the electrical appliances inside the power distribution cabinet. However, since the electrical appliances are arranged closely before, the heat accumulates between the electrical appliances. When the outside air enters the power distribution cabinet, due to the obstruction of some electrical appliances, it is impossible to directly dissipate and cool the electrical appliances. It only takes away the heat outside the electrical appliances with the flow of air, thereby reducing the heat dissipation effect of the power distribution cabinet. Utility Model Content

A plurality of heat dissipation fins 14 are evenly arranged. By setting the heat dissipation fins 14, the heat generated by the electrical appliances can be absorbed to reduce the accumulation of heat between the electrical appliances. The number of the heat dissipation ports 5 is set to two, and they are respectively arranged at the upper and lower parts of the cabinet 1. Two ventilation pipes 15 are symmetrically arranged on the front and rear sides of the air guide tube 6 in the lower heat dissipation port 5.
