Description

Technical Field

[0001] This utility model relates to the field of busbar trunking technology, specifically a busbar trunking cover with air convection. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute large power to various components of a distributed system. As a new type of power distribution conductor, busbar trunking is becoming increasingly popular. It has advantages such as long service life, high safety performance, convenient power supply, easy installation, and small installation space.

[0003] For busbar trunking, good heat dissipation is essential to ensure the service life of the trunking and its insulation materials. Most existing busbar trunking systems are enclosed structures with poor overall heat dissipation. During operation, busbar trunking generates a lot of heat, which can easily damage internal electrical components and reduce the service life of the busbar trunking. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a busbar trunking cover with air convection, which solves the problem that existing busbar trunking covers rely mainly on heat conduction for heat dissipation of the main components of the busbar trunking, resulting in poor heat dissipation for internal components.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A busbar trunking cover with air convection includes an upper cover and a lower cover arranged on the upper and lower end faces of the main body of the busbar trunking. Both the upper cover and the lower cover are provided with a plurality of convection heat dissipation holes, and a convection heat dissipation channel communicating with the convection heat dissipation holes is arranged between the upper cover and the lower cover.

[0009] Preferably, the upper cover plate and the lower cover plate have the same shape and are symmetrically arranged on the upper and lower end faces of the main body of the busbar trunking, and waterproof corrugated protrusions are symmetrically arranged on the end faces of the upper cover plate and the lower cover plate near the main body of the busbar trunking.

[0010] Preferably, the convection heat dissipation holes are arranged independently of each other and are any one of circular, elliptical, or polygonal shapes.

[0011] Preferably, the two convection heat dissipation holes are interconnected.

[0012] Preferably, the upper cover plate and the lower cover plate are integrally formed from magnesium-aluminum alloy.

[0013] (III) Beneficial Effects

[0014] This utility model has the following beneficial effects:

[0015] This busbar trunking cover with air convection, through the convection heat dissipation holes arranged on the upper and lower cover plates, enables air convection to be formed during the use of the busbar trunking. This facilitates efficient heat dissipation for the main components of the busbar trunking, effectively ensuring its heat dissipation performance, preventing heat accumulation on the cover plate or the main components of the busbar trunking, and extending the service life of the components and insulation parts inside the busbar trunking.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution: a busbar trunking cover with air convection, including an upper cover plate 1 and a lower cover plate 5 arranged on the upper and lower end faces of the main busbar trunking component 4. Both the upper cover plate 1 and the lower cover plate 5 are provided with a plurality of convection heat dissipation holes 2. A convection heat dissipation channel 6 communicating with the convection heat dissipation holes 2 is arranged between the upper cover plate 1 and the lower cover plate 5.

[0024] This utility model, through the convection heat dissipation holes 2 arranged on the upper cover plate 1 and the lower cover plate 5, enables the bus trunk to form air convection during use through the convection heat dissipation holes 2 and the convection heat dissipation channel 6, thereby efficiently dissipating heat from the main component 4 of the bus trunk, effectively ensuring the heat dissipation performance of the bus trunk, avoiding heat accumulation on the cover plate or the main component 4 of the bus trunk, and improving the service life of the components and insulating parts inside the bus trunk.

[0025] Reference Figure 3 As shown, in this embodiment, the upper cover plate 1 and the lower cover plate 5 are identical in shape and symmetrically arranged on the upper and lower end faces of the busbar trunking main assembly 4. Waterproof corrugated protrusions 3 are symmetrically arranged on the end faces of both the upper cover plate 1 and the lower cover plate 5 near the busbar trunking main assembly 4. By setting the upper and lower cover plates 5 to have identical shapes, processing steps and production costs can be reduced. The waterproof corrugated protrusions 3 facilitate cooperation with the sealing assembly to further improve the sealing performance between the cover plate and the busbar trunking main assembly 4, thereby extending the service life of the internal components of the busbar trunking main assembly 4.

[0026] Reference Figure 4 As shown, in this embodiment, the convection cooling holes 2 are arranged independently and can be any one of circular, elliptical, or polygonal shapes. By setting convection cooling holes 2 of various shapes, different shapes of convection cooling holes 2 can be selected according to actual application needs, thereby improving the efficiency of convection exchange and further improving the heat dissipation performance of the busbar trunking main component 4.

[0027] Reference Figure 5 As shown, in this embodiment, the two convection heat dissipation holes 2 are interconnected. By connecting the two convection heat dissipation holes 2 to each other, the air convection exchange efficiency between the upper cover plate 1 and the lower cover plate 5 can be further improved, the overall heat exchange efficiency can be improved, and the heat dissipation performance of the entire busbar trunking can be guaranteed.

[0028] In this embodiment, the upper cover plate 1 and the lower cover plate 5 are integrally formed from magnesium-aluminum alloy. Magnesium-aluminum alloy has excellent lightweight, corrosion resistance, and heat resistance, which can effectively reduce the weight of the upper cover plate 1 and the lower cover plate 5 and ensure the stability of the cover plate after installation, thus extending the service life of the entire busbar trunking.
