Description

Technical Field

[0001] This utility model relates to the field of heat dissipation bracket technology, and in particular to an electrical busbar trunking. Background Technology

[0002] In layman's terms, busbar trunking is used to support and organize electrical wires. Busbar trunking is commonly used in low-voltage power transmission trunk line projects, mainly including power supply and distribution sites such as factories, commercial centers, high-rise buildings, data centers, and lighting systems.

[0003] For example, publication number CN221828571U discloses an electrical busbar trunking system, including a base plate, a side plate at the top of the base plate, a top plate at the top of the side plate, heat sinks on both sides of the side plate, and fixed supports at both ends of both sides of the side plate. A limit plate is provided at one end of each fixed support, and a dust cover is provided on the surface of the limit plate. An insulating layer is provided on the surface of the conductive sheet, and a first fireproof cotton is provided on the surface of the insulating layer. A partition is provided on the other side of the first fireproof cotton, and a second fireproof cotton is provided on the other side of the partition. This invention, through the provision of the first and second fireproof cotton, effectively wraps the conductive sheet inside during use, thereby preventing fires and improving the safety of the busbar trunking. The dust cover, which slides at the connection points at both ends of the busbar trunking, provides protection for the conductive sheet, thus reducing energy consumption caused by dust on the surface of the conductive sheet.

[0004] The aforementioned patent improves heat dissipation by transferring the heat generated during operation to the surface of the heat sink. However, the problem remains: relying solely on the heat sink itself for heat dissipation can lead to heat accumulation on the heat sink, making it difficult to dissipate heat in a timely manner and significantly reducing the heat dissipation effect. Therefore, there is a need for an electrical busbar trunking that can effectively dissipate heat. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology of traditional electrical busbar trunking, which relies solely on the heat sink itself for heat dissipation. The heat absorbed on the heat sink is easily accumulated and it is difficult to dissipate the heat in time, which greatly reduces the heat dissipation effect. Therefore, this utility model proposes an electrical busbar trunking.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrical busbar trunking, comprising a busbar trunking body, wherein a heat dissipation device is provided on the outside of the busbar trunking body, the heat dissipation device comprising four bolts, the arc surfaces of the four bolts being fixedly connected to the busbar trunking body, an L-shaped block being slidably connected to the arc surfaces of the bolts, a U-shaped plate being fixedly connected to one end of the four L-shaped blocks, a cooling fan being fixedly connected to one side of the U-shaped plate, two connecting plates being fixedly connected to one side of the U-shaped plate, two elastic sheets being fixedly connected to one side of the connecting plates, and heat-conducting fins being fixedly connected to one end of the two elastic sheets.

[0007] The effect achieved by the above components is that the cooling fan starts to generate cold airflow, which is then transported to the heat-conducting fins, thereby blowing away the heat absorbed by the heat-conducting fins from the busbar trunking.

[0008] Preferably, one end of the cooling fan is fixedly connected to two fixing blocks, and one side of the two fixing blocks is fixedly connected to an air guide plate.

[0009] The aforementioned components achieve the following effect: the fixing block is fixed on the cooling fan, thus fixing the air guide plate.

[0010] Preferably, a retaining ring is fixedly connected to one side of the U-shaped plate, and a rubber retaining block is interference-fitted inside the retaining ring.

[0011] The effect achieved by the above components is that the rubber block and the groove ring are compatible.

[0012] Preferably, an arc-shaped block is fixedly connected to one side of the rubber block, and a dust filter is fixedly connected to one side of each of the four arc-shaped blocks.

[0013] The above components achieve the following effect: the dust filter and the arc-shaped block are fixed, and the arc-shaped block is fixed on the rubber clip.

[0014] Preferably, the busbar trunking body is provided with a protective device on its exterior. The protective device includes a retaining plate, one side of which is fixedly connected to the busbar trunking body, and a rubber retaining rod is interference-fitted inside the retaining plate.

[0015] The effect achieved by the above components is that the rubber clamp rod and the clamp plate are compatible.

[0016] Preferably, a mounting plate is fixedly connected to one side of the rubber clamp.

[0017] The aforementioned components achieve the effect of fixing the mounting plate and rubber clamp.

[0018] Preferably, a protective cover is fixedly connected to one side of the mounting plate.

[0019] The effect achieved by the above components is that the movement of the protective cover causes the mounting plate to move.

[0020] Preferably, the protective cover is slidably connected to two limit plates on both sides, and the side of the two limit plates that are close to each other is fixedly connected to the slot plate.

[0021] The effect achieved by the above components is to prevent the protective cover from shifting position.

[0022] Preferably, the protective cover has two U-shaped blocks slidably connected to its exterior, and one side of each U-shaped block is fixedly connected to a U-shaped plate.

[0023] The effect achieved by the above components is that the U-shaped block limits the movement of the protective cover after it slides into the protective cover.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] In this invention, when the electrical busbar trunking needs to dissipate heat during operation, the cooling fan starts to generate a cold airflow that blows away the heat absorbed on the heat-conducting fins. This heat dissipation device solves the problem that in traditional electrical busbar trunking, heat is easily accumulated on the heat sinks due to their fins, making it difficult to dissipate heat in a timely manner and greatly reducing the heat dissipation effect.

[0026] In this invention, a protective cover is installed to protect the copper busbars of the electrical busbar from damage during transportation. The protective cover can then protect the copper busbars of the busbar body. This solves the problem that traditional electrical busbars are easily damaged by impacts during transportation because they lack protective components for the copper busbars.

[0033] Reference Figure 1 As shown, this utility model provides a technical solution: an electrical busbar trunking, including a busbar trunking body 1, a heat dissipation device 2 on the outside of the busbar trunking body 1, and a protective device 3 on the outside of the busbar trunking body 1.

[0034] The specific setup and function of its heat dissipation device 2 and protection device 3 will be explained below.

[0035] Reference Figure 2 , Figure 3 and Figure 5 As shown in this embodiment: the heat dissipation device 2 includes four bolts 201. The arc surfaces of the four bolts 201 are fixedly connected to the busbar trunking body 1. L-shaped blocks 202 are slidably connected to the arc surfaces of the bolts 201. A U-shaped plate 203 is fixedly connected to one end of each L-shaped block 202. A cooling fan 204 is fixedly connected to one side of the U-shaped plate 203. Two connecting plates 205 are fixedly connected to one side of the U-shaped plate 203. Two elastic plates 206 are fixedly connected to one side of each connecting plate 205. A heat-conducting fin 207 is fixedly connected to one end of each elastic plate 206. This achieves the effect of the cooling fan 204 generating a cold airflow, which is then transported to the heat-conducting fins 207, thereby blowing away the heat absorbed by the heat-conducting fins 207 from the busbar trunking body 1. Two fixing blocks 213 are fixedly connected to one end of the cooling fan 204. An air guide plate 208 is fixedly connected to one side of each fixing block 213. The fixing block 213 is fixed to the cooling fan 204, achieving the effect of fixing the air guide plate 208. A retaining ring 209 is fixedly connected to one side of the U-shaped plate 203, and a rubber retaining block 211 is interference-fitted inside the retaining ring 209. This achieves the effect of the rubber retaining block 211 and the retaining ring 209 fitting together. An arc-shaped block 210 is fixedly connected to one side of the rubber retaining block 211, and a dust filter 212 is fixedly connected to one side of each of the four arc-shaped blocks 210. This achieves the effect of fixing the dust filter 212 to the arc-shaped blocks 210, and fixing the arc-shaped blocks 210 to the rubber retaining block 211.

[0036] Reference Figure 4As shown in this embodiment: the protective device 3 includes a slot plate 31, one side of which is fixedly connected to the busbar trunking body 1. A rubber clamp rod 32 is interference-fitted inside the slot plate 31, achieving a matching effect between the rubber clamp rod 32 and the slot plate 31. A mounting plate 33 is fixedly connected to one side of the rubber clamp rod 32, achieving a fixed effect between the mounting plate 33 and the rubber clamp rod 32. A protective cover 35 is fixedly connected to one side of the mounting plate 33, achieving the effect that the movement of the protective cover 35 drives the movement of the mounting plate 33. Limiting plates 34 are slidably connected to both sides of the protective cover 35, with the side of the two limiting plates 34 that is close to each other fixedly connected to the slot plate 31. This achieves the effect that the limiting plates 34 prevent the protective cover 35 from shifting position. Two U-shaped blocks 36 are slidably connected to the outside of the protective cover 35, with one side of the two U-shaped blocks 36 fixedly connected to a U-shaped plate 203. This achieves the effect that after the protective cover 35 slides into the U-shaped blocks 36, the U-shaped blocks 36 limit the position of the protective cover 35.

[0037] Working principle: When the electrical busbar needs to be cooled during operation, the operator first connects the cooling fan 204 to the controller to control its on / off state. After the busbar body 1 starts working, the cooling fan 204 is turned on. The cooling fan 204 generates a cold airflow, which is directed to the air guide plate 208. The air guide plate 208 guides the cold airflow onto the heat-conducting fins 207. Because the heat-conducting fins 207 are pressed against the surface of the busbar body 1 by the elastic force applied by the elastic plate 206, the heat generated inside the busbar body 1 is continuously absorbed. When the cold airflow is directed to the heat-conducting fins 207, the heat absorbed on the heat-conducting fins 207 is blown away. Through the cooling device 2, the problem of traditional electrical busbars relying solely on the heat sinks for heat dissipation, where heat is easily accumulated on the heat sinks and difficult to dissipate in time, greatly reducing the heat dissipation effect, is solved.

[0038] With the protective device 3, when it is necessary to prevent the copper busbars of the electrical busbar trunking from being damaged by bumps during transportation, the operator first moves the protective cover 35 towards the copper busbars of the busbar trunking body 1 until the mounting plate 33 drives the rubber clamp 32 and the clamping plate 31 to complete the assembly. After the protective cover 35 slides into the U-shaped block 36, the protective cover 35 can protect the copper busbars of the busbar trunking body 1. With the protective device 3, the problem of traditional electrical busbar trunking being easily damaged by bumps during transportation is solved because there are no protective components for the copper busbars.
