Description

Technical Field

[0001] This invention relates to an air-type busbar trunking with an internal circulating heat dissipation device. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections.

[0003] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute larger power to various components of a distributed system; it has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0004] Existing busbar trunking generates heat during operation, which can pose safety hazards if not dissipated in time. In addition, existing busbar trunking is prone to moisture ingress when operating in humid environments, which can also create safety hazards. Furthermore, busbar trunking often uses a splicing and assembly structure, which is prone to shaking and has poor installation stability. Therefore, an air-type busbar trunking with an internal circulating heat dissipation device has emerged. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an air-type busbar trunking with an internal circulating heat dissipation device.

[0006] An air-type busbar trunking with an internal circulating heat dissipation device includes an outer ring, an inner ring inside the outer ring, and a busbar trunking housing outside the outer ring. Both ends of the outer and inner rings are connected by cover plate rings. The inner ring includes multiple equidistantly arranged convex rings, with adjacent convex rings connected by concave rings. Each convex ring has multiple mounting openings on its sidewall, and fan blades are horizontally mounted inside each mounting opening. The fan blades are rotatably connected to the convex rings on both sides via rotating shafts. Each concave ring has a fixing ring abutting its inner sidewall. Each fixing ring has a fan mounting mechanism inside, and a fan is installed inside each fan mounting mechanism. The sidewall of the fan mounting mechanism is connected to the fixing ring via multiple connecting plates.

[0007] As a further improvement, the busbar trunking outer shell includes multiple heat dissipation shells, and adjacent heat dissipation shells are connected by sealing shells. The busbar trunking outer shell is an integrally formed structure, and the manufacturing process is simple. The number of heat dissipation shells is equal to the number of sealing plates, the sealing shells have the same area, the heat dissipation shells have the same area, and the area of ​​the heat dissipation shells is smaller than the area of ​​the sealing shells. The heat generated inside the busbar trunking outer shell is discharged through heat dissipation holes.

[0008] As a further improvement, the surface of the heat dissipation shell is provided with multiple heat dissipation holes. These holes are used to dissipate heat energy from the busbar trunking shell, preventing the heat generated inside from being unable to dissipate and avoiding heat accumulation. This ensures normal internal operation, improves the safety of the busbar during use, and achieves the effect of automatic circulating heat dissipation.

[0009] As a further improvement, multiple sealing plates are provided between the outer ring and the outer casing of the busbar trunking. Each sealing plate is connected to the outer wall of the outer ring via a connecting rod. When the sealing plate overlaps with the heat dissipation housing, the outer casing of the busbar trunking is sealed, preventing external dust and liquids from entering and ensuring the cleanliness of the busbar trunking. This allows it to be used in harsher environments, extending its service life and applicability. When the sealing plate overlaps with the sealing housing, the outer casing of the busbar trunking is opened, providing heat dissipation and ensuring a normal internal temperature, preventing overheating and further extending its service life and applicability.

[0010] As a further improvement, the outer casing, outer ring, and inner ring of the busbar trunking are all circular, which is simple in structure, easy to install, and the special structural design can effectively avoid vibration and impact caused by external force.

[0011] As a further improvement, the sealing plate is arc-shaped and abuts against the outer shell of the busbar trunking. The arc design provides better sealing, strong structural stability, and convenient installation and use.

[0012] As a further improvement, the inner ring has an "S" shaped cross-section, which is simple in structure.

[0013] As a further improvement, the connecting plate, fixing ring, and inner ring are all made of ceramic material. The inner and outer rings are provided with multiple heat dissipation openings on their surfaces. Ceramic material has advantages such as heat dissipation, insulation, thermal conductivity, and durability, which greatly extends the service life of the busbar trunking and accelerates heat dissipation, thereby improving the heat dissipation effect. Beneficial effects

[0014] This device adopts a special circular structure design to improve the stability of the entire structure. At the same time, the integrated design avoids shaking and deformation. The heat dissipation and sealing effect can be achieved by rotating the sealing plate. The structure is simple and easy to adjust. It can not only keep the bus trunking clean and tidy, but also be more suitable for harsher environments, thus improving the scope of use and service life. It can also dissipate heat, prevent internal moisture and water ingress, and reduce the possibility of safety accidents. It solves the shortcomings of existing bus trunking with spliced ​​assembly structure, which is prone to shaking, has poor installation stability, and poor heat dissipation.

[0015] This device controls the rotation of fan blades to accelerate the circulation of heat energy inside the busbar trunking, thus achieving the function of heat dissipation. It has a simple structure and is easy and convenient to operate. It effectively avoids excessive temperature inside the busbar trunking, prevents damage to its internal cables, and improves the reliability and safety of the busbar trunking. It solves the shortcomings of existing busbar trunking, which generate heat during operation and pose safety hazards if not dissipated in time. Moreover, existing busbar trunking is prone to moisture ingress when operating in humid environments, which also poses certain safety hazards. Attached Figure Description

[0017] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] like Figures 1-3 As shown in a specific embodiment of the present invention, an air-type busbar trunking with an internal circulating heat dissipation device includes a busbar trunking outer shell 1, a sealing plate 2, a cover ring 3, a mounting opening 4, a fan blade 5, a connecting plate 6, a fan mounting mechanism 7, an inner ring 8, and an outer ring 9.

[0019] An air-type busbar trunking with an internal circulating heat dissipation device includes an outer ring 9, an inner ring 8 inside the outer ring 9, and a busbar trunking housing 1 outside the outer ring 9. The two ends of the outer ring 9 and the inner ring 8 are connected by a cover plate ring 3. The inner ring 8 includes multiple convex rings arranged in an equidistant array, and adjacent convex rings are connected by concave rings. Each convex ring has multiple mounting openings 4 on its sidewall. Fan blades 5 are horizontally mounted inside each mounting opening 4. Both sides of the fan blades 5 are rotatably connected to the convex rings through a rotating shaft. Each concave ring has a fixing ring abutting its inner sidewall. Each fixing ring has a fan mounting mechanism 7 inside its fixing ring. Each fan mounting mechanism 7 has a fan installed inside its fan mounting mechanism 7. The sidewall of the fan mounting mechanism 7 is connected to the fixing ring through multiple connecting plates 6.

[0020] The busbar trunking outer shell 1 includes multiple heat dissipation shells, and adjacent heat dissipation shells are connected by sealing shells. The busbar trunking outer shell 1 is an integrally formed structure, and the manufacturing process is simple. The number of heat dissipation shells is equal to the number of sealing plates 2. The sealing shells have the same area, and the heat dissipation shells have the same area. The area of ​​the heat dissipation shells is smaller than the area of ​​the sealing shells. The heat generated inside the busbar trunking outer shell 1 is discharged through heat dissipation holes.

[0021] The surface of the heat dissipation shell is provided with multiple heat dissipation holes. These holes are used to dissipate the heat energy inside the busbar trunking shell 1, preventing the heat energy generated inside from not being able to dissipate, and preventing the heat energy from accumulating. This ensures normal internal operation, improves the safety of the busbar during use, and achieves the effect of automatic circulating heat dissipation.

[0022] Multiple sealing plates 2 are provided between the outer ring 9 and the outer casing 1 of the busbar trunking. The sealing plates 2 are all connected to the outer wall of the outer ring 9 through connecting rods. When the sealing plate 2 overlaps with the heat dissipation shell, the outer casing 1 of the busbar trunking is sealed. At this time, external dust and liquid cannot enter, ensuring the cleanliness of the busbar trunking and making it more suitable for harsher environments, thus improving its service range and lifespan. When the sealing plate 2 overlaps with the sealing shell, the outer casing 1 of the busbar trunking is opened. At this time, it plays a heat dissipation role, ensuring the normal internal temperature of the busbar trunking and preventing its internal temperature from becoming too high, thus improving its service range and lifespan.

[0023] The outer casing 1, outer ring 9, and inner ring 8 of the busbar trunking are all circular in shape, which is simple in structure and easy to install. The special structural design can effectively avoid vibration and impact caused by external force.

[0024] The sealing plate 2 is arc-shaped and abuts against the outer shell 1 of the busbar trunking. The arc design can provide better sealing, has strong structural stability, and is easy to install and use.

[0025] The inner ring has an "S" shaped cross-section, making its structure simple.

[0026] The connecting plate 6, the fixing ring, and the inner ring 8 are all made of ceramic. The inner ring 8 and the outer ring 9 are provided with multiple heat dissipation openings. Ceramic material has the advantages of heat dissipation, insulation, thermal conductivity, and durability, which greatly extends the service life of the busbar trunking and accelerates the heat dissipation speed and improves the heat dissipation effect.

[0027] In use, the fan is remotely controlled, starting and stopping via a control device. When the fan is on, it blows the blades to rotate, dissipating heat. Then, rotating the sealing plate seals and opens the busbar trunking casing. When the sealing plate and the heat dissipation housing are in contact, the busbar trunking casing is sealed, preventing external dust and liquids from entering, ensuring cleanliness and allowing it to be used in harsher environments, thus extending its service life. When the sealing plate and the sealing housing are in contact, the busbar trunking casing opens, providing heat dissipation and ensuring a normal internal temperature, preventing overheating and further extending its service life. The structure is simple and easy to adjust.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
