Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically relating to a high heat dissipation busbar. Background Technology

[0002] In order to reduce the heat generated by the busbar trunking during operation and prevent damage caused by overheating, the existing technology will install heat dissipation fins on the outer shell of the busbar trunking to dissipate the heat generated by the busbar trunking.

[0003] However, under harsh operating conditions, the heat dissipation effect of heat dissipation fins will deteriorate due to the adhesion of dust and other substances. Therefore, existing technologies have developed devices for cleaning dust from heat dissipation fins, such as a heat dissipation busbar trough with patent number CN202420620856.8, which includes: a shell, a busbar, and a dust removal component. The shell includes a mounting bracket and a heat dissipation plate. The mounting bracket has a mounting groove. The heat dissipation plate includes a plate body and heat dissipation fins. The plate body is connected to the mounting bracket and has a ventilation groove. The ventilation groove is arranged along the length direction of the plate body. The heat dissipation fins are disposed in the ventilation groove. The busbar is snapped into the mounting groove. The dust removal component is slidably disposed in the ventilation groove and is in contact with the heat dissipation fins.

[0004] While existing devices can achieve a certain degree of scraping and dust removal to improve the heat dissipation of busbar trunking, their scraping and dust removal effect is limited in actual use, and they are easily blocked by dust, resulting in poor sliding performance. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a high heat dissipation busbar trunking to improve the heat dissipation effect of the busbar trunking.

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

[0007] A high-heat-dissipation busbar trunking includes a busbar trunking body. A plurality of heat dissipation fins are symmetrically arranged on the outer surface of the busbar trunking body. Exhaust pipes are provided between adjacent heat dissipation fins, and the exhaust pipes have a plurality of exhaust holes. An annular air supply pipe is provided on the outer surface of one end of the busbar trunking body, and the annular air supply pipe is connected to one end of the plurality of exhaust pipes. An air supply assembly is provided on the annular air supply pipe for introducing air into the annular air supply pipe. The air supply assembly is connected to the outer surface of the busbar trunking body. An annular sealing pipe is provided on the other end of the busbar trunking body, and the annular sealing pipe seals the other end of the plurality of exhaust pipes. A fixing block is provided on the outer surface of the busbar trunking body, and the fixing block fixes the annular air supply pipe and the annular sealing pipe to the busbar trunking body.

[0008] Furthermore, the air supply assembly includes a first air pump and a second air pump, which are symmetrically arranged. Both the first air pump and the second air pump are fixed on the outer surface of the busbar trunking body, and the output ends of both the first air pump and the second air pump are connected to the annular air supply pipe through connecting pipes.

[0009] Furthermore, the annular air supply pipe is equipped with a first control valve and a second control valve, and the connecting pipes of the first air pump and the second air pump to the annular air supply pipe are respectively located between the first control valve and the second control valve.

[0010] Furthermore, a sealing tube is fitted over the exhaust pipe, and the sealing tube is slidably disposed on the exhaust pipe. The sealing tube has a plurality of connecting holes that match the position of the exhaust hole. When the connecting holes are misaligned with the exhaust hole, the sealing tube blocks the exhaust hole on the exhaust pipe.

[0011] Furthermore, a U-shaped plate is provided on one end of a plurality of symmetrically arranged sealing tubes, the ends of the plurality of sealing tubes are fixed on the U-shaped plate, a U-shaped frame is provided on the symmetrically arranged U-shaped plate, and a drive component for controlling the sliding of the sealing tubes is provided on the U-shaped frame.

[0012] Furthermore, the driving component is a symmetrically arranged linear push rod, which is fixed to the surface of the busbar trunking body, and the output end of the linear push rod is fixed to the closed end of the U-shaped frame.

[0013] Furthermore, several exhaust holes are evenly distributed around the circumference of the exhaust pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] This technical solution pumps air into the annular air supply pipe. The high-speed airflow enters the exhaust pipe and is discharged from the exhaust port. The discharged air acts on the surface of several heat dissipation fins, which can cool the surface of the heat dissipation fins, accelerate heat dissipation, and speed up the heat exchange effect of the heat dissipation fins. At the same time, it can also blow away the dust adhering to the heat dissipation fins, preventing dust from sticking, thereby improving the cooling efficiency of the busbar trunking and ensuring the cooling effect of the busbar trunking.

[0016] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0025] like Figures 1-5 As shown, a high-heat-dissipation busbar trunking includes a busbar trunking body 1. A plurality of heat dissipation fins 2 (existing technology, which can be understood as heat-conducting copper sheets) are symmetrically arranged on the outer surface of the busbar trunking body 1. An exhaust pipe 4 is provided between adjacent heat dissipation fins 2, and the exhaust pipe 4 has a plurality of exhaust holes 10. An annular air supply pipe 5 is provided on the outer surface of one end of the busbar trunking body 1, and the annular air supply pipe 5 is connected to one end of the plurality of exhaust pipes 4. An air supply assembly is provided on the annular air supply pipe 5 to introduce air into the annular air supply pipe 5. The air supply assembly is connected to the outer surface of the busbar trunking body 1. An annular sealing pipe 15 is provided on the other end of the busbar trunking body 1, sealing the other end of the plurality of exhaust pipes 4. A fixing block 6 is provided on the outer surface of the busbar trunking body 1, fixing the annular air supply pipe 5 and the annular sealing pipe 15 to the busbar trunking body 1.

[0026] The working principle of the above technical solution is as follows:

[0027] When the temperature inside the busbar trunking body 1 is too high, simply turn on the air supply component to pump air into the annular air supply pipe 5. The high-speed airflow enters the exhaust pipe 4 and is discharged from the exhaust port 10. The discharged air acts on the surface of several heat dissipation fins 2, which can cool the surface of the heat dissipation fins 2, accelerate heat dissipation, and speed up the heat exchange effect of the heat dissipation fins 2. At the same time, it can also blow away the dust adhering to the heat dissipation fins 2, prevent dust from adhering, and thus improve the cooling efficiency inside the busbar trunking body 1, ensuring the cooling effect of the busbar trunking.

[0028] In one feasible embodiment, the air supply assembly includes a first air pump 7 and a second air pump 16, which are symmetrically arranged. Both the first air pump 7 and the second air pump 16 are fixed to the outer surface of the busbar trunking body 1, and their output ends are connected to the annular air supply pipe 5 via connecting pipes. The symmetrical arrangement of the first air pump 7 and the second air pump 16 allows them to work in coordination and alternately, avoiding damage caused by long-term operation in high-temperature environments. This redundant arrangement ensures that even if one fails, the other can continue to operate, facilitating maintenance without shutting down the system.

[0029] In one feasible embodiment, the annular air supply pipe 5 is equipped with a first control valve 8 and a second control valve 17. The connecting pipes of the first air pump 7 and the second air pump 16 connected to the annular air supply pipe 5 are respectively located between the first control valve 8 and the second control valve 17. It can be understood that the first control valve 8 and the second control valve 17 divide the annular air supply pipe 5 into two parts, and the connecting pipes of the first air pump 7 and the second air pump 16 are respectively located in the two parts of the annular air supply pipe 5. The advantage of this arrangement is that the air supply operation can be performed separately by the two air pumps on several exhaust pipes 4 at two symmetrically arranged positions, which can improve the effect of uniformly entering several exhaust pipes 4 and increase the gas flow rate and pressure in each exhaust pipe 4, so as to ensure the air supply effect in high heat environment or emergency cooling situation.

[0030] In one feasible embodiment, a sealing pipe 9 is fitted over the exhaust pipe 4. The sealing pipe 9 is slidably mounted on the exhaust pipe 4 and has several connecting holes 11 that match the positions of the exhaust holes 10. When the connecting holes 11 are offset from the exhaust holes 10, the sealing pipe 9 blocks the exhaust holes 10 on the exhaust pipe 4. The sealing pipe 9 can be slidably used to block and open the exhaust holes 10. That is, when cooling is not required, the exhaust holes 10 of the exhaust pipe 4 are blocked to prevent dust, insects and other foreign objects from entering the exhaust pipe 4 under harsh working conditions and causing blockage (when there is airflow during operation, foreign objects will not enter).

[0031] In one feasible embodiment, a plurality of symmetrically arranged sealing tubes 9 are provided with a U-shaped plate 12 at one end, and the ends of the sealing tubes 9 are fixed to the U-shaped plate 12. A U-shaped frame 13 is provided on the symmetrically arranged U-shaped plate 12, and a drive assembly for controlling the sliding of the sealing tubes 9 is provided on the U-shaped frame 13. In another feasible embodiment, the drive assembly is a symmetrically arranged linear push rod 14, which is fixed to the surface of the busbar trunking body 1, and the output end of the linear push rod 14 is fixed to the closed end of the U-shaped frame 13. That is, by the U-shaped frame 13 acting on the U-shaped plate 12, the plurality of sealing tubes 9 can be driven to move synchronously at the same time, improving the movement effect and speed. Of course, the drive assembly can be manually pulled to move the U-shaped plate 12 or electrically driven. In this technical solution, the linear push rod 14 is used for driving. The linear push rod 14 is preferably symmetrically arranged, and the synchronous movement of the linear push rods 14 on both sides under the control system or control program is the prior art, which will not be described in detail here.

[0032] In one feasible approach, a number of exhaust holes 10 are evenly distributed around the exhaust pipe 4, which facilitates the setting of the connecting holes 11 on the sealing pipe 9, and at the same time can act on a larger area on the heat dissipation fins 2, further improving the heat dissipation effect.

[0033] It should be noted that the structure and components of the main body 1 of the busbar trunking are existing technologies and will not be elaborated upon here. For example, the tubular busbar trunking in the existing technology should include: conductors (busbars), usually hollow copper or aluminum tubes, which carry current transmission and have low skin effect and high current carrying capacity; insulation layer, wrapped around the conductor, commonly made of PVC, cross-linked polyethylene, epoxy resin, etc., which serves as insulation and temperature resistance; shielding layer, made of semi-conductive material or metal braided mesh, used to balance the electric field distribution and prevent partial discharge; outer shell (sheath), usually made of metal (aluminum or steel) or high-strength plastic, providing mechanical protection, fireproof, moisture-proof and corrosion-proof functions; connectors / joints, including terminals, connectors, plug boxes, etc., used for inter-section connection, branching or system expansion, and connection terminals 3 at the ends of the outer shell, etc.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
