Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a track-type busbar for power applications. Background Technology

[0002] Busbar trunking is a device used for power transmission and distribution. It is primarily constructed of copper or aluminum busbars, enclosed in a metal enclosure, and is used to distribute significant power to various components of a system. Busbar trunking typically consists of a metal plate as a protective casing, conductive bars, insulating materials, and related accessories, and features high conductivity and stability.

[0003] Patent CN219760585U discloses a waterproof busbar trunking, which includes a busbar trunking body. A waterproof component is provided on one side of the connection end of the busbar trunking body. The waterproof component is set at both ends of the busbar trunking body with a staggered arrangement. The waterproof component includes a sealing plug. A sealing flexible plate is fixed to the upper end of the sealing plug. By setting the waterproof component, the busbar trunking body can form a sealed space through the sealing plug and the sealing flexible plate after installation and connection. In this way, the upper and lower ends of the busbar trunking body will not be affected by water. In addition, fixing the plug strip around the sealing plug can make the whole structure more stable.

[0004] However, this device only seals the connected busbar trunking with waterproof components to improve waterproofing. But the heat generated at the busbar trunking connection is much greater than that at other locations. Even if the connection is completely sealed with sealing plugs, sealing plates, etc., it will greatly reduce the heat dissipation performance at the busbar trunking connection, resulting in heat accumulation and overheating. This can easily cause equipment failure and may also lead to risks such as leakage. Therefore, a track-type busbar trunking for power applications is proposed to solve the problem of poor heat dissipation at the connection of existing busbar trunking, which affects normal operation.

[0015] (III) Beneficial Effects

[0016] 1. This power rail-type busbar trunking moves the heat dissipation connection shell to the middle position of the two busbar trunking bodies. After being limited by the limiting connection mechanism, when heat is generated at the connection point of the busbar trunking, the heat conduction plate installed in the trunking is used to conduct the heat out through the heat sink. At the same time, the heat dissipation fan in the fixed base is turned on to blow air towards the heat sink, which accelerates the air flow on the surface and improves the heat dissipation efficiency. This solves the problem of poor heat dissipation at the connection point of the existing busbar trunking, which affects normal operation.

[0017] 2. In the process of moving the heat dissipation connecting shell between two connected busbar trunking bodies, the limiting slider in the limiting groove improves the stability of the heat dissipation connecting shell during movement. When the limiting slider moves to one end of the limiting groove, the connecting bolt can be turned to screw the connecting bolt into the connecting screw hole in the limiting connecting block in the other busbar trunking body, connecting the heat dissipation connecting shell to the two busbar trunking bodies, further improving the firmness of the busbar trunking connection.

[0023] 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.

[0024] Example: Please refer to Figure 1-4 A track-type busbar trunking for power applications includes a busbar trunking body 1. A heat dissipation connecting shell 2 is slidably disposed at the outer end of the busbar trunking body 1. The busbar trunking body 1 and the heat dissipation connecting shell 2 are connected by a limiting connecting mechanism 3. An installation groove 4 is opened at the top of the inner cavity of the heat dissipation connecting shell 2. A heat conduction plate 5 is disposed in the inner cavity of the installation groove 4. A heat dissipation fin 6 is disposed at the top of the heat conduction plate 5. A fixing seat 7 is fixedly connected to the top of the heat dissipation connecting shell 2. Two cooling fans 8 are symmetrically arranged in the inner cavity of the fixing seat 7.

[0025] Furthermore, both the heat-conducting plate 5 and the heat sink 6 are made of materials with good thermal conductivity. The heat sink 6 penetrates the heat-conducting plate 5 and communicates with the inner cavity of the heat dissipation connecting shell 2.

[0026] Furthermore, the limiting connection mechanism 3 includes limiting grooves 301 symmetrically opened on both sides of the heat dissipation connecting shell 2. A limiting slider 302 is slidably connected to the inner cavity of one end of the limiting groove 301, and a limiting connecting block 303 is fixedly connected to the inner cavity of the other end of the limiting groove 301.

[0027] Furthermore, the limiting slider 302 is fixedly connected to the heat dissipation connecting shell 2. A connecting screw hole 304 is provided on one side of the limiting connecting block 303. Connecting bolts 305 are threaded through and screwed onto both sides of the heat dissipation connecting shell 2. During the process of moving the heat dissipation connecting shell 2 between the two connected busbar trunking bodies 1, the limiting slider 302 in the limiting groove 301 improves the stability of the movement of the heat dissipation connecting shell 2. When the limiting slider 302 moves to one end of the limiting groove 301, the connecting bolt 305 can be rotated to screw the connecting bolt 305 into the connecting screw hole 304 in the limiting connecting block 303 in the other busbar trunking body 1, connecting the heat dissipation connecting shell 2 to the two busbar trunking bodies 1, further improving the firmness of the busbar trunking connection.

[0028] Furthermore, a guide shell 9 is provided at one end of the fixed base 7. The guide shell 9 is hollow inside and has an exhaust slot 10 at the end facing the heat sink 6. The inner cavity of the guide shell 9 is connected to the air outlet of the cooling fan 8. When the cooling fan 8 is turned on, the blown air will enter the interior of the guide shell 9 and then be evenly blown onto the heat sink 6 from the exhaust slot 10. This ensures that the blown air can pass through the surface of all heat sinks 6, thus ensuring the heat dissipation effect at the connection of the power rail busbar.

[0029] Furthermore, a protective shell 11 is provided on the top of the heat dissipation connection shell 2. The protective shell 11 protects the heat dissipation fan 8 and heat sink 6 inside the fixed base 7, preventing damage to the structural components caused by falling objects, stepping or impact, which would affect the normal use of the busbar trunking.

[0030] Furthermore, sealing ring grooves 12 are provided at the top and bottom of the inner cavity of the heat dissipation connection shell 2. A sealing strip 13 is provided in the inner cavity of the sealing ring groove 12. The sealing strip 13 is in interference fit contact with the bus trunk body 1. The sealing strip 13 in the sealing ring groove 12 increases the sealing between the heat dissipation connection shell 2 and the bus trunk body 1, improves the heat dissipation at the connection of the bus trunk, and ensures the sealing at the connection of the bus trunk, so as to avoid water vapor erosion at the connection and damage to the connection of the bus trunk.

[0031] Working principle: When using this power rail-type busbar trunking, after connecting two busbar trunking bodies 1 together, the heat dissipation connecting shell 2 is moved to the middle position of the two busbar trunking bodies 1. After being limited by the limiting connecting mechanism 3, when heat is generated at the connection point of the busbar trunking, the heat is conducted out through the heat sink 6 by the heat conduction plate 5 in the mounting slot 4. At the same time, the heat dissipation fan 8 in the fixing base 7 is turned on, blowing air towards the heat sink 6 to accelerate the surface airflow and improve the heat dissipation efficiency, thus solving the problem of poor heat dissipation at the connection point of existing busbar trunking that affects normal operation. During the process of moving the heat dissipation connecting shell 2 between the two connected busbar trunking bodies 1, the limiting slider 302 in the limiting slot 301 improves the stability of the movement of the heat dissipation connecting shell 2. When the limiting slider 302 moves to one end of the limiting slot 301, the connecting bolt 305 is rotated, and the connecting bolt 305 can be screwed into the connecting screw hole 304 in the limiting connecting block 303 in the other busbar trunking body 1, connecting the heat dissipation connecting shell 2 to the two busbar trunking bodies 1, further improving the firmness of the busbar trunking connection.
