Description

Technical Field

[0001] This utility model relates to the field of busbar cooling housing, and more particularly to a busbar cooling housing. Background Technology

[0002] Busbar trunking is a closed conductive system used for transmitting and distributing high currents. It is a new type of conductor formed by using copper or aluminum as conductors, supported by non-aluminum insulation, and then installed in a metal trough. The internal structure of the busbar trunking uses copper or aluminum busbars as conductors, providing excellent conductivity, while the external structure is encased in a robust and durable metal shell for protection.

[0003] The busbar trunking shell is a crucial component of the busbar trunking system, primarily serving to protect the internal conductors, insulation materials, and other accessories. Busbar trunking shells are mainly made of steel plates, aluminum alloy plates, and plastics. Steel plate shells are corrosion-resistant, wear-resistant, and have high structural strength, making them suitable for installations in harsh environments such as ships, mines, and docks. Aluminum alloy shells are lightweight, easy to process, and aesthetically pleasing, making them suitable for installations in refined environments such as high-rise buildings, shopping malls, and factories. Plastic shells offer good insulation, are lightweight, and are corrosion-resistant, making them suitable for installations in environments such as computer rooms and offices. Busbar trunking shells have diverse structures, but they typically include four symmetrical snap-fit ​​plates (top, bottom, left, and right), which are connected by snap-fit ​​mechanisms to form a closed busbar trunking cavity. The top-bottom symmetrical snap-fit ​​plates are called snap-fit ​​cover plates, and the left-right symmetrical snap-fit ​​plates are called snap-fit ​​side plates. The snap-fit ​​side plate and snap-fit ​​cover plate engage to form a busbar trunking cavity inside. The cavity consists of multiple electrical-specific screws, nuts, special conductor clamps, clamp pads, and conductors (copper or aluminum). The busbar trunking housing prevents external dust and moisture from entering the busbar trunking, avoiding contamination, corrosion, and damage to the equipment, thereby improving its service life. The busbar trunking housing also prevents personnel from accidentally touching the live parts inside the busbar trunking, protecting personal safety.

[0004] In the design and application of busbar trunking, the heat dissipation housing is a crucial component. Its design directly impacts the busbar trunking's operational efficiency and safety. Traditional busbar trunking cooling methods typically rely on natural convection or simple forced ventilation, which may fail to meet cooling requirements under certain high-load or special environmental conditions. This can lead to excessively high busbar trunking temperatures, affecting transmission efficiency and potentially causing safety issues due to overheating.

[0005] With the increasing demand for electricity and the trend towards energy conservation and environmental protection in electrical equipment, effectively improving the heat dissipation performance of busbar trunking has become an urgent problem to be solved. Therefore, developing new heat dissipation shells with high-efficiency heat dissipation characteristics has become one of the key research focuses in the field of electrical engineering. These new heat dissipation shells not only need to have excellent heat dissipation performance, but also need to meet requirements such as lightweight structure, low manufacturing cost, and convenient installation to adapt to the development needs of modern power systems.

[0006] When existing busbar trunking is in operation, the internal conductors generate heat, which is transferred to the outer shell of the busbar trunking, causing the shell temperature to rise and resulting in damage, thereby reducing the service life of the busbar trunking shell.

[0007] Therefore, it is particularly important to design a busbar housing that can be used for heat dissipation. Utility Model Content

[0008] This application provides a busbar heat dissipation housing, which adopts the following technical solution:

[0009] A busbar cooling housing includes a housing with upper and lower corresponding housings, a busbar array between the two housings, and side plates on both sides of the housing. The housing is connected and fixed to the side plates by nuts. The housing is characterized by having raised fins on its surface, the fins including long fins and short fins, the long fins and short fins being staggered and arranged, and protrusions at the tips of the long fins and short fins.

[0010] Optionally, the height ratio of short fins to long fins ranges from 1:2 to 2.5.

[0011] Optionally, the height of the protrusions on the long fins shall not exceed two-thirds of the overall height of the long fins.

[0012] Optionally, the height of the protrusions on the short fins shall not exceed two-thirds of the overall height of the short fins.

[0013] Optionally, the housing material can be any one of aluminum alloy, copper alloy, titanium alloy or plastic composite material.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: the design of the busbar trunking heat dissipation shell effectively improves heat dissipation, significantly reduces the temperature rise of the busbar trunking during operation, thereby enhancing the safety and stability of the system; its special heat dissipation structure can not only quickly dissipate heat during operation, but also prevent heat accumulation in the shell, reducing the impact of temperature rise on the insulation performance of the busbar trunking and extending its service life; at the same time, the optimized shell structure increases the contact area with air, and the heat is carried away by airflow, ensuring rapid heat dissipation, further ensuring the efficient operation of the equipment, and improving the reliability and service life of the overall system.

[0023] An embodiment of this utility model provides a busbar heat dissipation housing.

[0024] Example 1: As Figure 1-2 As shown, a busbar cooling housing includes a housing 1, which is C-shaped and has corresponding upper and lower sections. A busbar 3 is provided between the two housing sections 1, and side plates 2 are provided on both sides of the housing 1. The housing 1 is connected and fixed to the side plates 2 by nuts 4.

[0025] The surface of the housing 1 is provided with raised fins, which include long fins 5 and short fins 6. The long fins 5 and short fins 6 are arranged in a staggered manner. The tips of the long fins 5 and short fins 6 are provided with protrusions. The purpose of providing long fins 5 and short fins 6 is to increase the contact area between the fins on the housing 1 and the air. The protrusions on the long fins 5 and short fins 6 further increase the contact area with the air. The air flow and contact with the housing 1 remove the heat from the housing 1, thereby reducing the heat on the housing 1 and preventing the busbar housing 1 from overheating and causing damage.

[0026] The height ratio of short fin 6 to long fin 5 ranges from 1:2 to 2.5.

[0027] The height of the protrusion on the long fin 5 shall not exceed two-thirds of the overall height of the long fin 5;

[0028] The height of the protrusion on the short fin 6 shall not exceed two-thirds of the overall height of the short fin 6.

[0029] The shell 1 is made of aluminum alloy, which has good thermal conductivity and can effectively transfer heat.

[0030] Optionally, in certain specific cases, the material of the housing 1 can also be a copper alloy, titanium alloy, or plastic composite material.

[0031] like Figure 3 As shown, this is a double-layer busbar structure, where two busbars are combined together. Additional busbars can be added as needed.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims.
