Description

A kind of bus duct omnirange convection heat dissipation structure

Technical field

The utility model relates to transmission facility, especially a kind of bus duct structure.

Background technology

Existing common compact bus bar groove organization plan is as Fig. 1, and from schematic diagram direction, left and right two shell A is connected by the mode such as bolt or riveted joint with upper and lower two shell B, clamps the conductor 2 wrapped up by insulation material layer 1.As shown in Figure 2, the compact bus bar shell of this organization plan and the direct contact surface of conductor only have two, easily cause the heat radiation of bus duct entirety poor, especially two phase conductors in the middle of, owing to there is no heat-dissipating space, temperature rise meeting can be caused higher, directly reduce the useful life of bus duct.

Utility model content

The purpose of this utility model is to overcome prior art bus duct overall structure and dispels the heat poor technical problem, provides one can increase conductor and bus duct housing contacts area, increases the bus duct omnirange convection heat dissipation structure of heat-dissipating space.

For realizing above object, the utility model takes following technical scheme: a kind of bus duct omnirange convection heat dissipation structure, for clamping the conductor wrapped up by insulation material layer, comprise the upper groove body shell, middle slot body case and the lower groove shell that are respectively equipped with spacing between opposite face, described conductor is placed in the cavity surrounded separately by upper groove body shell, middle slot body case and lower groove shell respectively, and insulation material layer and cavity inner wall are fitted; Also include two connectors, the two ends of upper groove body shell, middle slot body case and lower groove shell are connected on this connector, and described upper groove body shell, middle slot body case, lower groove shell are surrounded by heat-dissipating space between face, between connector opposite face toward each other.

This structure can form six direct radiating surfaces on bus duct surface, is upper groove body upper surface of outer cover respectively, two faces that upper groove body shell is relative with middle slot body case, two faces that middle slot body case is relative with lower groove shell, and lower groove shell lower surface.Cause to improve dense conductor in bus duct difficult problem of dispelling the heat, improve radiating efficiency.

Described connector comprises bolt and cushion block, the two ends of described upper groove body shell and lower groove shell are connected on bolt, and the position that described cushion block is arranged is: on the vertical direction at bolt place, between upper groove body shell and middle slot body case, between middle slot body case and lower groove shell; Described heat-dissipating space is respectively the region surrounded between upper groove body shell lower surface, the upper surface of middle slot body case and two cushion block opposite faces, and, the region surrounded between the lower surface of middle slot body case, the upper surface of lower groove shell and two cushion block opposite faces.

The utility model compared with prior art, tool has the following advantages: be compared to existing compact bus bar groove organization plan, the compact bus bar groove of the utility model structure, the radiating surface that conductor and shell directly contact is six, substantially increase the integral heat sink efficiency of bus duct, especially some for centre conductors are separated and form multiple heat-dissipating space, reduce the temperature rise of bus duct, make the serviceability of bus duct more reliable, useful life can be guaranteed.

Embodiment

Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.

Embodiment one:

Refer to shown in Fig. 3 to Fig. 5, a kind of bus duct omnirange convection heat dissipation structure, for clamping the conductor 2 wrapped up by insulation material layer 1, comprise the upper groove body shell 3, middle slot body case 4 and the lower groove shell 5 that are respectively equipped with spacing between opposite face, conductor 2 is placed in the cavity surrounded separately by upper groove body shell 3, middle slot body case 4 and lower groove shell 5 respectively, insulation material layer 1 and cavity inner wall are fitted, and particularly fit with the inner surface up and down of corresponding shell respectively; Also include two connectors, the two ends of upper groove body shell 3, middle slot body case 4 and lower groove shell 5 are connected on this connector, upper groove body shell 3, middle slot body case 4, lower groove shell 5 are surrounded by heat-dissipating space between face, between connector opposite face toward each other, this structure can form six direct radiating surfaces on bus duct surface, upper groove body upper surface of outer cover respectively, two faces that upper groove body shell is relative with middle slot body case, two faces that middle slot body case is relative with lower groove shell, and lower groove shell lower surface.

In the present embodiment, connector comprises bolt 6 and cushion block 7, the two ends of upper groove body shell 3 and lower groove shell 4 are connected on bolt 6, and the position that cushion block 7 is arranged is: on the vertical direction at bolt 6 place, between upper groove body shell 3 and middle slot body case 4, between middle slot body case 4 and lower groove shell 5; Heat-dissipating space is respectively the region surrounded between upper groove body shell bottom surface, the upper surface of middle slot body case and two cushion block 7 opposite faces, and, the region surrounded between the lower surface of middle slot body case, the upper surface of lower groove shell and two cushion block 7 opposite faces.
