Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a heat-dissipating busbar. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of various 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. As a new type of power distribution conductor, plug-in busbar trunking has emerged. Compared with traditional cables, it fully demonstrates its superiority and safety reliability in high-current transmission, which has led to its widespread use.

[0003] During use, existing air-cooled busbar trunking generates a large amount of heat. Although cooling fans can help dissipate heat, this method has limited effectiveness. As the heat generated by the busbar trunking continues to accumulate, it will remain at a certain temperature and cannot be lowered, thus affecting the service life of the busbar trunking.

[0004] Based on this, a heat-dissipating busbar trunking is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a heat-dissipating busbar trunking to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat-dissipating busbar trunking includes two busbar trunking frames connected by two top covers. Sealing plates are fixedly connected to both ends of the two busbar trunking frames. Each sealing plate has a mounting groove containing a busbar conductor. An insulating sleeve is provided at the outer end of each busbar conductor. Ventilation holes are provided on both busbar trunking frames, and heat dissipation boxes are fixedly connected to the vents. One of the heat dissipation boxes contains a cooling mechanism. Both heat dissipation boxes have ventilation openings containing ventilation components.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative embodiment: the refrigeration mechanism includes a cooling pipe disposed in a heat dissipation box, the outer end of the cooling pipe is provided with a support block, the support block is fixedly connected to the inner wall of the heat dissipation box, the outlet of the cooling pipe is connected to the inlet of the compressor, the outlet of the compressor is connected to the inlet of the condenser, the liquid outlet of the condenser is connected to the liquid inlet of the cooling pipe through an expansion valve, and the compressor, condenser and expansion valve are located in the heat dissipation box.

[0010] In one alternative: the ventilation component includes a fan, which is fixedly connected to the vent, and a dustproof plate is connected to the vent via a disassembly unit.

[0011] In one alternative embodiment: the disassembly unit includes two grooves located on a dustproof plate, with a slidably connected locking block in each groove. Each groove is equipped with a spring, one end of which is fixedly connected to the locking block, and the other end of which is fixedly connected to the inner wall of the groove. The dustproof plate has two sliding grooves that connect the grooves to the outside. A pull rod is slidably connected in the sliding grooves and fixedly connected to the locking block. The vent has a locking groove that engages with the locking block.

[0012] In one alternative: the outer frame of the busbar trunking is provided with superabsorbent resin near the vent of the refrigeration mechanism.

[0015] In one alternative: the two grooves are symmetrically arranged on both sides of the dustproof plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a heat-dissipating busbar trunking includes two busbar trunking frames 100 connected by two top covers 200. Sealing plates 101 are fixedly connected to both ends of the two busbar trunking frames 100. Each sealing plate 101 has a mounting groove 102, in which a busbar conductor 103 is placed. An insulating sleeve 104 is provided at the outer end of each busbar conductor 103. Ventilation holes 105 are provided on both busbar trunking frames 100, and heat dissipation boxes 106 are fixedly connected to the ventilation holes 105. One heat dissipation box 106 contains a cooling mechanism, and both heat dissipation boxes 106 have ventilation openings 107. Each ventilation opening 107 contains a ventilation component. The ventilation component draws outside air through the cooling mechanism, cools it, and then blows it into the busbar trunking for further cooling. The hot air generated by the busbar trunking is then discharged through the other side, improving the heat dissipation effect of the busbar trunking and increasing its service life.

[0026] In this embodiment, as Figure 2 and Figure 5As shown, the refrigeration mechanism includes a cooling pipe 201, which is disposed in a heat dissipation box 106. A support block 202 is provided at the outer end of the cooling pipe 201, and the support block 202 is fixedly connected to the inner wall of the heat dissipation box 106. The outlet of the cooling pipe 201 is connected to the inlet of the compressor 203, and the outlet of the compressor 203 is connected to the inlet of the condenser 204. The liquid outlet of the condenser 204 is connected to the liquid inlet of the cooling pipe 201 through an expansion valve 205. The compressor 203, the condenser 204, and the expansion valve 205 are located in the heat dissipation box 106. The refrigerant in the cooling pipe 201 absorbs heat from the air. After absorbing heat, the refrigerant is pressurized by the compressor 203 and then enters the condenser for heat exchange, carrying away heat and causing the refrigerant to gradually condense into a liquid state. It then re-enters the cooling pipe 201 through the expansion valve 205 for heat exchange.

[0027] In one embodiment, such as Figure 3 As shown, the ventilation component includes a fan 301, which is fixedly connected to the vent 107. A dustproof plate 302 is connected to the vent 107 via a disassembly unit. The fan 301 near the cooling pipe 201 blows air into the heat sink 106, where it is cooled by the heat absorption of the cooling pipe 201 before entering the busbar trunking for further cooling. The fan 301 on the other side exhausts the hot air generated by the busbar trunking, thus improving the heat dissipation effect of the busbar trunking. The dustproof plate 302 prevents dust in the air from entering the busbar trunking.

[0028] In one embodiment, such as Figure 4 As shown, the disassembly unit includes two grooves 401 located on the dustproof plate 302. A locking block 402 is slidably connected within each groove 401. A spring 403 is provided in each groove 401; one end of the spring 403 is fixedly connected to the locking block 402, and the other end is fixedly connected to the inner wall of the groove 401. Two sliding grooves 404 are provided on the dustproof plate 302, connecting the grooves 401 to the outside. A sliding mechanism is provided within the sliding grooves 404. A connecting rod 405 is fixedly connected to a locking block 402. A slot 406 is provided at the ventilation opening 107 to cooperate with the locking block 402. When the connecting rod 405 is moved, it slides in the sliding groove 404 and drives the locking block 402 to move into the groove 401. The locking block 402 compresses the spring 403 and leaves the slot 406, making it easy to remove the dustproof plate 302 for disassembly and cleaning, thus preventing dust adhering to the dustproof plate from reducing the heat dissipation effect on the busbar trunking.

[0029] In one embodiment, such as Figure 2 As shown, the outer frame 100 of the busbar trunking is provided with super absorbent resin 500 near the vent 105 of the refrigeration mechanism to prevent moisture in the air from entering the busbar trunking and corroding the components in the busbar trunking.

[0030] In one embodiment, such as Figure 2 As shown, the outer end of the cooling pipe 201 is provided with a hydrophilic coating. The hydrophilic coating enables the condensate to form a uniform water film on the surface, rather than water droplets. This can increase the evaporation rate of the water film, remove more heat, and enhance the heat dissipation effect.

[0031] In one embodiment, such as Figure 2 As shown, the top cover 200 is provided with heat dissipation fins 600 on the side near the bus conductor 103, which can increase the contact area between the top cover 200 and the air, increase air turbulence, and improve heat dissipation efficiency.

[0032] In one embodiment, such as Figure 1 As shown, the two grooves 401 are symmetrically arranged on both sides of the dustproof plate 302, making the dustproof plate 302 more secure and preventing it from falling off.

[0033] The above embodiment discloses a heat dissipation busbar trunking. A fan 301 near the cooling pipe 201 blows air into the heat sink 106. The air is cooled by the heat absorption of the cooling pipe 201. After heat exchange between the refrigerant in the cooling pipe 201 and the air, the refrigerant is pressurized by the compressor 203 and then enters the condenser for heat exchange, carrying away heat and gradually condensing into a liquid state. The liquid then re-enters the cooling pipe 201 through the expansion valve 205 for heat exchange. The cooled air enters the interior of the busbar trunking for further cooling. The fan 301 on the other side exhausts the hot air generated by the busbar trunking, improving the heat dissipation effect of the busbar trunking. A movable lever 405 slides in the slide groove 404, causing the locking block 402 to move into the groove 401. The locking block 402 compresses the spring 403, disengaging from the groove 406, facilitating the removal and cleaning of the dustproof plate 302, preventing dust adhering to the dustproof plate from reducing the heat dissipation effect of the busbar trunking.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
