Efficient heat-dissipation type bus duct

Abstract

The invention relates to the field of bus ducts, in particular an efficient heat-dissipation type bus duct. The bus duct comprises a bus duct shell which is a hollow structure, the bus duct shell comprises a top plate, a support frame and a bottom plate, multi-group of electric conductors are arranged in a placing cavity of the support frame, and a plastic insulating layer is filled in the placing cavity; a side plate at each of two sides of the support frame is provided with a heat conducting layer, the outside of the heat conducting layer is provided with a heat-dissipation net layer, heat-dissipation curved sheets and heat-dissipation ribs are respectively arranged between the heat-dissipation net layer and the heat conducting layer, the heat-dissipation curved sheets are arranged in waveform, and the heat-dissipation curved sheets and the heat-dissipation ribs are respectively fixed and connected with the heat-dissipation net layer; the bottom surface of the bottom plate is provided with a rubber cushion. The bus duct disclosed by the invention is simple in structure and low in cost, the structure of multi-layer of heat-dissipation and cooling is adopted so that the heat is fast volatilized, the aim of heat-dissipating, cooling and damping through the bus duct shell is achieved, the normal use of the bus duct is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of bus ducts, in particular to a high-efficiency heat dissipation bus duct. Background technique [0002] As a new type of distribution wire, bus duct has become more and more popular. It has the advantages of long service life, high safety performance, convenient power feeding, easy installation, and small installation space. The traditional busway includes a shell, which is composed of a cover plate and a side plate. With the continuous improvement of the current capacity, the busway uses air conduction to dissipate heat, and dissipates the heat through the steel or aluminum shell in close contact, but Under this heat dissipation method, the heat dissipation area is small, and the heat dissipation effect of the bus duct is not ideal. In order to ensure the long-term normal use of the bus duct, the heat dissipation requirements for it are getting higher and higher. Contents of the invention [0003] The ...
