Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct heat dissipation structure. Background Art

[0002] The bus duct in the prior art is generally composed of a bus duct housing, a clamp located inside the bus duct housing, a conductive copper busbar, and a cover plate located on the bus duct housing.

[0003] In the prior art, in the process of dissipating heat from the conductive copper busbar in the bus duct, heat dissipation holes are generally opened on both sides of the bus duct shell or heat dissipation fins are added on both sides of the bus duct shell. Although these two methods can dissipate heat, the air circulation is slow and the heat dissipation efficiency is not high. Heat is easily accumulated in the bus duct shell, affecting the normal use of the bus duct. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a bus duct heat dissipation structure, which can increase the air flow in the shell and improve the heat dissipation efficiency.

[0005] The utility model discloses a bus duct heat dissipation structure, comprising a shell, a clamp is arranged in the shell, a copper bar is arranged on the clamp, a cover plate is arranged on the shell, air inlet holes are evenly arranged on the bottom surface of the shell, an air outlet hole is arranged in the middle of the cover plate, a V-shaped guide plate is arranged on the upper end of the shell, both side ends of the V-shaped guide plate are fixedly connected to the shell, through holes are evenly arranged on both side surfaces of the V-shaped guide plate near the two side ends, and a heat insulation layer is arranged on the cover plate directly above the through holes.

[0006] The principle of the above technical solution is that the heat generated by the copper busbar when it is powered on heats the air in the shell, the heated air rises and contacts the V-shaped guide plate, then flows to both sides along the V-shaped guide plate and enters between the V-shaped guide plate and the insulation layer from the through holes on the V-shaped guide plate, and finally flows out through the air outlet in the middle of the cover plate, while the cooler air flows into the shell from the air inlet. The function of the insulation layer is to isolate and prevent the hot air coming out of the through hole from encountering the cover plate and becoming cold and sinking, affecting the outflow of the hot air in the through hole. The function of the V-shaped guide plate is to guide the hot air in the shell to flow out, and at the same time, the dust falling from the air outlet will accumulate in the middle of the V-shaped guide plate, thereby reducing the dust entering the shell.

[0007] Furthermore, the lower end surface of the heat insulation layer is inclined upward toward the air outlet, which can further guide the hot air to flow out from the air outlet.

[0008] Preferably, the thermal insulation layer is an aerogel thermal insulation layer, which has a good thermal insulation effect.

[0009] The utility model provides a bus duct heat dissipation structure, which has the beneficial effect that, through the design of the V-shaped guide plate and the heat insulation layer, not only can the hot air be effectively discharged from the air outlet, the air flow in the shell is increased, the heat dissipation efficiency is increased, but also the dust entering the shell can be effectively reduced.

The function of the insulation layer 6 is to isolate and prevent the hot air coming out of the through hole 5 from encountering the cover plate 7 and becoming cold and sinking, affecting the outflow of the hot air in the through hole 5. The function of the V-shaped guide plate 9 is to guide the hot air in the shell 1 to flow out, and at the same time, the dust falling from the air outlet 8 will accumulate in the middle of the V-shaped guide plate 9, thereby reducing the dust entering the shell 1.
