Description

Technical Field

[0001] This invention relates to the field of power transmission trunk line technology, specifically a busbar trunking with high-efficiency heat dissipation function. Background Technology

[0002] Enclosed busbar trunking, or simply busbar trunking, is a busbar system composed of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulation materials, and related accessories. It can be manufactured as a plug-in type enclosed busbar with plug-in junction boxes at intervals, or as a feeder type enclosed busbar without junction boxes in the middle. In the power supply systems of high-rise buildings, power and lighting circuits are often installed separately, and busbar trunking serves as the main power supply line, installed vertically along the wall in electrical shafts, one or more times. Busbar trunking can be classified into three types according to its insulation method: air-insulated plug-in busbar trunking, compact insulated plug-in busbar trunking, and high-strength plug-in busbar trunking. According to its structure and application, it can be classified into compact insulated, air-insulated, air-supplemented insulated, fire-resistant, resin-insulated, and sliding contact busbar trunking. Busbar trunking has outstanding advantages such as high current carrying capacity, low voltage drop, low power loss, simple branching, convenient installation and maintenance, and long service life, and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] The compact type, which began in the mid-1980s, involves covering the busbar with insulating material and then fastening it to both sides. The insulating material is PTFE tape, which can operate at temperatures up to 200 degrees Celsius. However, a drawback is that it produces deadly toxic gases when decomposed at high temperatures.

[0004] As the most widely used type of busbar trunking, heat dissipation and insulation have always been the most pressing issues to address. Poor heat dissipation will cause the internal temperature of the busbar trunking to rise, affecting power transmission and causing some wear and tear on the insulation material. In severe cases, it may even directly cause a fire, resulting in extremely serious losses and failing to meet societal needs. Therefore, a busbar trunking with efficient heat dissipation function is proposed to solve the aforementioned problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a busbar trunking with efficient heat dissipation, which has advantages such as good heat dissipation effect. This solves the problems of poor heat dissipation effect of existing busbar trunking, which affects power transmission and causes some loss of insulation materials, and in severe cases, may directly cause fire.

[0006] To achieve the aforementioned good heat dissipation effect, the present invention provides the following technical solution: a bus trunking with high-efficiency heat dissipation function, comprising a bus trunking body, an mounting plate disposed on one side of the bus trunking body, and a mounting box disposed on one side of the inner wall of the bus trunking body. The bus trunking body is provided with a heat dissipation device for dissipating heat inside the bus trunking body. The heat dissipation device includes a cooling fan fixedly installed on the inner wall of the bus trunking body. A heat dissipation groove is provided on the side of the bus trunking body away from the cooling fan.

[0007] The busbar trunking body is provided with a heat absorption device for absorbing heat near the heat dissipation tank. The heat absorption device includes a heat absorption box fixedly installed outside the heat dissipation tank and a heat absorption plate fixedly installed inside the heat absorption box. The heat absorption plate is located on the side close to the heat dissipation tank, and a heat absorption frame is fixedly installed on the side of the heat absorption box away from the heat absorption plate.

[0008] A cooling device for cooling the heat-absorbing sheet is provided on one side of the mounting plate and extending into the interior of the heat-absorbing frame. The cooling device includes a circulating cooling water pipe fixedly installed inside the heat-absorbing frame, a booster pump fixedly installed on one side of the mounting plate, and a cooling tank. An outlet pipe is fixedly connected between the circulating cooling water pipe and the booster pump, an inlet pipe is fixedly connected between the circulating cooling water pipe and the cooling tank, and a connecting pipe is fixedly connected between the booster pump and the cooling tank.

[0009] Furthermore, the mounting box has an air outlet on the side near the heat dissipation slot, and the height of the heat dissipation slot is consistent with the height of the cooling fan.

[0010] Furthermore, an air inlet is provided inside the busbar trunking body on the side near the mounting box, and a dustproof plate is provided on the outside of the air inlet.

[0011] Furthermore, the dustproof plate is fixedly connected to the outer wall of the busbar trunking body by fixing bolts, and a dustproof net is fixedly connected inside the dustproof plate.

[0012] Furthermore, the heat absorption box is a hollow cuboid, the outer diameter of the heat absorption box is larger than the inner diameter of the heat dissipation groove, and the number of heat absorption plates is multiple.

[0013] Furthermore, the heat-absorbing frame is a hollow cuboid, and both the heat-absorbing frame and the heat-absorbing box have heat dissipation holes inside.

[0014] Furthermore, the circulating cooling water pipe is externally secured with a fixing buckle, which is fixedly connected to the outer wall of the heat absorption frame.

[0015] Furthermore, the booster pump is fixedly connected to a mounting base on the side near the mounting plate, and the cooling box is a hollow cylinder.

[0016] Furthermore, a water inlet pipe is fixedly connected to one side of the cooling tank, and coolant is added inside the cooling tank.

[0017] Furthermore, two connecting plates are fixedly connected to one side of the mounting plate, and the mounting plate is fixedly connected to the wall through the two connecting plates.

[0018] Compared with the prior art, the present invention provides a busbar trunking with high-efficiency heat dissipation function, which has the following beneficial effects:

[0019] 1. This busbar trunking with high-efficiency heat dissipation function has heat dissipation grooves inside the busbar trunking body, which facilitates natural heat dissipation of the conductive busbars inside the busbar trunking body. Then, by starting the cooling fan, the heat inside the busbar trunking body is blown into the heat absorption box, and then the heat inside the heat absorption box is absorbed by multiple heat absorption fins, thus achieving the advantage of good heat dissipation effect.

[0020] 2. This busbar trunking with high-efficiency heat dissipation function has circulating cooling water pipes inside the heat absorption frame. These pipes facilitate the absorption of heat from the heat absorption box, thus cooling the heat absorption fins. During the heat absorption process, the circulating cooling water pipes deliver coolant to the cooling box for cooling, effectively reducing the internal temperature of the heat absorption box and accelerating the cooling of the heat absorption fins. This achieves excellent heat dissipation, solving the problems of poor heat dissipation in existing busbar trunking, which affects power transmission and causes wear and tear on insulation materials, potentially leading to fires in severe cases.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4 This embodiment of a busbar trunking system with high-efficiency heat dissipation includes a busbar trunking body 1, a mounting plate 2 disposed on one side of the busbar trunking body 1, and a mounting box 3 disposed on one side of the inner wall of the busbar trunking body 1. The busbar trunking body 1 is internally equipped with a heat dissipation device for dissipating heat from its interior. The heat dissipation device includes a cooling fan 4 fixedly mounted on the inner wall of the busbar trunking body 1. A heat dissipation groove 5 is formed on the side of the busbar trunking body 1 away from the cooling fan 4. The heat dissipation groove 5 facilitates natural heat dissipation from the conductive busbars inside the busbar trunking body 1. Furthermore, by activating the cooling fan 4, the heat inside the busbar trunking body 1 is easily blown into the heat absorption box 8, achieving excellent heat dissipation.

[0028] Specifically, an air outlet is provided on the side of the mounting box 3 near the heat dissipation slot 5, and the height of the heat dissipation slot 5 is consistent with the height of the cooling fan 4. An air inlet 6 is provided on the side of the busbar trunking body 1 near the mounting box 3, and a dustproof plate 7 is provided on the outside of the air inlet 6. By providing the dustproof plate 7, external dust can be effectively prevented from entering the interior of the busbar trunking body 1 through the air inlet 6.

[0029] It should be noted that the dustproof plate 7 is fixedly connected to the outer wall of the busbar trunking body 1 by fixing bolts, and a dustproof net is fixedly connected inside the dustproof plate 7.

[0030] In this embodiment, a heat-absorbing device is provided on the outside of the busbar trunking body 1 to absorb heat near the heat dissipation slot 5. The heat-absorbing device includes a heat-absorbing box 8 fixedly installed outside the heat dissipation slot 5 and heat-absorbing sheets 9 fixedly installed inside the heat-absorbing box 8. The heat-absorbing sheets 9 are located on the side close to the heat dissipation slot 5, and a heat-absorbing frame 10 is fixedly installed on the side of the heat-absorbing box 8 away from the heat-absorbing sheets 9. By absorbing heat from the inside of the heat-absorbing box 8 through multiple heat-absorbing sheets 9, the temperature inside the heat-absorbing box 8 can be effectively reduced, achieving the advantage of good heat dissipation.

[0031] Specifically, the heat absorption box 8 is a hollow cuboid, the outer diameter of the heat absorption box 8 is larger than the inner diameter of the heat dissipation groove 5, and there are multiple heat absorption plates 9.

[0032] Specifically, the heat-absorbing frame 10 is a hollow cuboid, and both the heat-absorbing frame 10 and the heat-absorbing box 8 have heat dissipation holes 11 inside. By providing heat dissipation holes 11, the heat conducted by the heat dissipation groove 5 can be easily discharged through the heat dissipation holes 11.

[0033] In this embodiment, a cooling device for cooling the heat-absorbing sheet 9 is provided on one side of the mounting plate 2 and extending into the interior of the heat-absorbing frame 10. The cooling device includes a circulating cooling water pipe 12 fixedly installed inside the heat-absorbing frame 10, a booster pump 13 fixedly installed on one side of the mounting plate 2, and a cooling tank 14. An outlet pipe 15 is fixedly connected between the circulating cooling water pipe 12 and the booster pump 13, an inlet pipe 16 is fixedly connected between the circulating cooling water pipe 12 and the cooling tank 14, and a connecting pipe 17 is fixedly connected between the booster pump 13 and the cooling tank 14. The circulating cooling water pipe 12 inside the heat-absorbing frame 10 facilitates heat absorption from the heat-absorbing tank 8, thus facilitating the cooling of the heat-absorbing sheet 9. During the heat absorption process, the circulating cooling water pipe 12 delivers coolant to the interior of the cooling tank 14 for cooling, effectively reducing the temperature inside the heat-absorbing tank 8 and accelerating the cooling of the heat-absorbing sheet 9, achieving excellent heat dissipation.

[0034] Specifically, the circulating cooling water pipe 12 is externally secured with a fixing buckle, which is fixedly connected to the outer wall of the heat absorption frame 10. By setting the fixing buckle, it is easy to fix the circulating cooling water pipe 12, which can effectively enhance the stability of the installation of the circulating cooling water pipe 12. The booster pump 13 is fixedly connected to the mounting base on the side near the mounting plate 2, and the cooling box 14 is a hollow cylinder.

[0035] Specifically, a water inlet pipe 18 is fixedly connected to one side of the cooling tank 14, and coolant is added inside the cooling tank 14. The water inlet pipe 18 allows maintenance personnel to add coolant to the cooling tank 14 regularly.

[0036] In this embodiment, two connecting plates 19 are fixedly connected to one side of the mounting plate 2, and the mounting plate 2 is fixedly connected to the wall through the two connecting plates 19.

[0037] When using this embodiment:

[0038] The conductive busbars inside the busbar trunking 1 are naturally cooled by the heat dissipation grooves 5 inside the busbar trunking 1. Then, the heat inside the busbar trunking 1 is blown into the heat absorption box 8 by starting the cooling fan 4. Then, the heat inside the heat absorption box 8 is absorbed by multiple heat absorption plates 9. While the heat absorption plates 9 are absorbing heat, the heat inside the heat absorption box 8 is absorbed by the circulating cooling water pipes 12. During the heat absorption process, the circulating cooling water pipes 12 deliver coolant to the cooling box 14 for cooling until the heat inside the busbar trunking 1 drops to a suitable temperature.

[0039] The beneficial effects of the above embodiments are as follows:

[0040] The busbar trunking with high-efficiency heat dissipation function has heat dissipation grooves 5 inside the busbar trunking body 1, which facilitates natural heat dissipation of the conductive busbars inside the busbar trunking body 1. Then, by starting the cooling fan 4, the heat inside the busbar trunking body 1 is blown into the heat absorption box 8. Then, the heat inside the heat absorption box 8 is absorbed by multiple heat absorption plates 9, which achieves the advantage of good heat dissipation effect.

[0041] This busbar trunking with high-efficiency heat dissipation function has a circulating cooling water pipe 12 installed inside the heat absorption frame 10. The circulating cooling water pipe 12 facilitates the absorption of heat inside the heat absorption box 8 and the cooling of the heat absorption fins 9. During the heat absorption process, the circulating cooling water pipe 12 delivers coolant to the cooling box 14 for cooling, which can effectively reduce the temperature inside the heat absorption box 8 and accelerate the cooling of the heat absorption fins 9. This achieves the advantage of good heat dissipation and solves the problems of poor heat dissipation of existing busbar trunking, which affects power transmission and causes some damage to insulation materials, and in severe cases, may directly cause fire.
