Description

Technical Field

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

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute large power to various components of a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced wires and cables. Due to the power needs of various buildings such as buildings and factories, and this need is increasing year by year, the original circuit wiring method, namely the conduit method, brings many difficulties during construction. Moreover, it is almost impossible to simplify the power distribution system when it needs to be changed. Using busbar trunking can achieve the goal very easily. In addition, it can also make the building more aesthetically pleasing.

[0003] In practical applications, busbar trunking generates a lot of heat during operation due to the lack of effective heat dissipation methods. This causes heat to accumulate inside the busbar trunking, leading to an increase in internal temperature and affecting its normal connection and use. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-dissipating, easily connectable busbar trunking, comprising a busbar trunking body, copper conductors evenly distributed on the inner side of the busbar trunking body, end caps provided at the top and bottom of the busbar trunking body, a cooling pipe connected to the inner side of the busbar trunking body between two copper conductors, a liquid inlet pipe connected to the bottom of one end of the cooling pipe, and a liquid return pipe connected to the top of the other end of the cooling pipe;

[0006] The end of the return pipe is connected to a liquid storage box at the back of the busbar body. A micro liquid pump is connected to the bottom of the liquid storage box. The micro liquid pump is powered by an external power source. A liquid collection pipe is connected to the bottom of the micro liquid pump along the length of the busbar body. The inlet end of the inlet pipe is connected to the outlet end of the liquid collection pipe.

[0007] The back end face of the liquid storage box is uniformly provided with heat dissipation fins. The back of the busbar trunking body is equipped with a back shell located outside the liquid storage box, and the back shell is uniformly provided with heat dissipation grooves. Several sets of metal heat-conducting strips are embedded and connected to the top inner side of the end cover located at the top of the busbar trunking body, and an isolation net is embedded and installed on the top of the end cover.

[0008] Preferably, multiple sets of cooling pipes and liquid inlet pipes are equidistantly arranged along the length of the busbar trunking body, and the end cap has an internal cavity, with the corners of the liquid inlet pipes and cooling pipes located within the internal cavity.

[0009] Preferably, the liquid storage box is filled with coolant, and the micro liquid pump delivers the coolant to the liquid collection pipe, which then delivers the coolant to the liquid inlet pipe.

[0010] Preferably, the bottom end of the metal heat-conducting strip extends to the inner side of the built-in cavity, the back shell is detachably installed on the back of the busbar trunking body by bolts, and the back shell provides shielding for the outside of the liquid storage box, micro liquid pump, and liquid collection pipe.

[0012] The sliding seat is connected to a connecting seat at one end, and an insulating pressure plate is fixedly connected to the end of the connecting seat. A support plate is connected to the bottom of the insulating pressure plate along its vertical direction.

[0013] Preferably, the sliding seat and the threaded rod are connected by a thread, the connecting seat and the insulating pressure plate are positioned corresponding to the copper busbar of the conductor, and the distance between the connecting seat and the insulating pressure plate is equal.

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0015] 1. By equidistantly installing multiple sets of cooling pipes between adjacent copper busbars within the busbar trunking, combined with a circulating liquid delivery and distribution structure consisting of an inlet pipe, return pipe, storage box, micro liquid pump, and collecting pipe, the coolant in the storage box can be quickly and evenly distributed into the multiple sets of cooling pipes. This utilizes the coolant in the cooling pipes to absorb the heat generated by the copper busbars during operation, allowing the heat to be carried away with the flow of coolant, thus reducing the operating temperature of the copper busbars. Furthermore, the cooling pipes are arranged on the sides of adjacent copper busbars, and multiple sets of cooling pipes are installed to ensure the uniformity and sufficiency of the cooling treatment of the copper busbars, ensuring the stable long-term operation of the copper busbars.

[0016] 2. The heat dissipation fins on the side of the coolant reservoir allow heat to be conducted and dissipated as the coolant flows back into the reservoir. Combined with the heat dissipation grooves inside the back cover, heat can be quickly radiated and dissipated, reducing the internal temperature of the reservoir. Furthermore, the metal heat-conducting strips allow heat dissipated from the outside of the return pipe to be quickly conducted away during the coolant return process, resulting in a lower temperature of the coolant flowing back into the return pipe. This ensures that the coolant can be circulated and used for cooling, guaranteeing the continuous cooling effect of the cooling pipe on the copper busbars.

[0017] 3. By installing guide rails, threaded rods, sliding seats, rotating seats, connecting seats, insulating pressure plates, and support plates, the rotating seats drive the threaded rod to rotate, which in turn drives multiple sliding seats distributed on its outer side to move at equal distances. In turn, the sliding seats drive multiple connecting seats, insulating pressure plates, and support plates to move at equal distances. When the copper busbar is connected, the insulating pressure plate squeezes and limits the wire plate to which the copper busbar is connected, thus ensuring a tight contact between the copper busbar and the wire plate. The support plate provides convenient support and limitation for the bottom of the wire plate, thereby ensuring the accuracy of the position between the insulating pressure plate and the copper busbar.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-6 As shown, this utility model provides a technical solution: a heat-dissipating, easily connectable busbar trunking, including a busbar trunking body 1. Copper conductors 2 are evenly distributed on the inner side of the busbar trunking body 1. End caps 3 are provided at both the top and bottom of the busbar trunking body 1. A cooling pipe 4 is connected to the inner side of the busbar trunking body 1 between two copper conductors 2. A liquid inlet pipe 5 is connected to the bottom of one end of the cooling pipe 4. Multiple sets of cooling pipes 4 and liquid inlet pipes 5 are evenly distributed along the length of the busbar trunking body 1. An internal cavity 13 is provided inside the end cap 3, and the corners of the liquid inlet pipe 5 and the cooling pipe 4 are all located within the internal cavity 13. The multiple sets of cooling pipes 4 ensure uniform and sufficient cooling of the copper conductors 2, while facilitating the connection between the liquid inlet pipe 5 and the cooling pipe 4. A return pipe 6 is connected to the top of the other end of the cooling pipe 4.

[0029] The end of the return pipe 6 is connected to a storage box 7 at the back of the busbar trunking body 1. A micro liquid pump 8 is connected to the bottom of the storage box 7. The micro liquid pump 8 is powered by an external power source. The bottom of the micro liquid pump 8 is connected to a collection pipe 9 along the length of the busbar trunking body 1. The storage box 7 is filled with coolant. The micro liquid pump 8 delivers the coolant to the collection pipe 9. The collection pipe 9 delivers the coolant to the inlet pipe 5, which facilitates the rapid and even distribution of the coolant in the storage box 7 to multiple sets of cooling pipes 4. The coolant in the cooling pipes 4 absorbs the heat generated by the copper busbar 2 during operation, allowing the heat to be carried away with the flow of the coolant. The inlet end of the inlet pipe 5 is connected to the outlet end of the collection pipe 9.

[0030] The back end face of the liquid storage box 7 is uniformly provided with heat dissipation fins 10. The back shell 14 is installed on the back of the bus trunking body 1 at the position outside the liquid storage box 7. The bottom end of the metal heat conduction strip 11 extends to the inner side of the built-in cavity 13. The back shell 14 is detachably installed on the back of the bus trunking body 1 by bolts. The back shell 14 provides shielding treatment for the outside of the liquid storage box 7, the micro liquid pump 8, and the liquid collection pipe 9. With the metal heat conduction strip 11, the heat dissipated from the outside of the return pipe 6 can be quickly discharged through the metal heat conduction strip 11 during the process of the return pipe 6 driving the coolant back. This facilitates the installation and removal of the back shell 14. The back shell 14 also provides convenient shielding treatment for the outside of the liquid storage box 7, the micro liquid pump 8, and the liquid collection pipe 9. The back shell 14 is uniformly provided with heat dissipation grooves 15. Several sets of metal heat conduction strips 11 are embedded and connected to the top inner side of the end cover 3 located at the top of the bus trunking body 1. An isolation net 12 is embedded and installed on the top of the end cover 3.

[0031] The bottom of the wiring terminals on both sides of the busbar trunking body 1 is fixedly installed with mounting guide rails 16. The mounting guide rails 16 are embedded with a rotatable threaded rod 17. One end of the threaded rod 17 is connected to a rotating seat 19. The inner side of the mounting guide rails 16 is embedded with a sliding seat 18 corresponding to the side of the copper busbar 2.

[0032] The end of the sliding seat 18 is connected to the connecting seat 20, and the end of the connecting seat 20 is fixedly connected to the insulating pressure plate 21. The sliding seat 18 and the threaded rod 17 are connected by threads. The connecting seat 20 and the insulating pressure plate 21 correspond to the positions of the conductor copper busbar 2, and the distance between the connecting seat 20 and the insulating pressure plate 21 is equal. The rotating seat 19 drives the threaded rod 17 to rotate, which facilitates the equal-distance driving movement of the multiple sliding seats 18 distributed on its outer side. The insulating pressure plate 21 is used to squeeze and limit the conductor plate connected to the conductor copper busbar 2, so that the conductor copper busbar 2 is in close contact with the conductor plate it is connected to. The bottom of the insulating pressure plate 21 is connected to the support plate 22 along its vertical direction.

[0033] The working principle and usage process of this utility model: In the actual application process, when connecting the conductor copper busbar 2 inside the busbar body 1 with the external conductor plate, the external conductor plate is first attached to the edge of the conductor copper busbar 2, and the support plate 22 is used to support and limit the bottom of the conductor plate to ensure the accuracy of the position between the insulating pressure plate 21 and the conductor copper busbar 2.

[0034] Then, the rotating seat 19 drives the threaded rod 17 to rotate, and the threaded rod 17 drives the multiple sliding seats 18 distributed on its outer side to move at equal distances. The sliding seats 18 drive the multiple connecting seats 20, insulating pressure plate 21 and support plate 22 to move at equal distances, so that when the conductor copper busbar 2 is connected, the insulating pressure plate 21 squeezes and limits the conductor plate connected to the conductor copper busbar 2, so that the conductor copper busbar 2 and the conductor plate connected to it are in close contact.

[0035] During the actual operation of the busbar trunking 1, when a large amount of heat accumulates on the outside of the copper busbar 2 inside it, the micro liquid pump 8 is started to transport the coolant in the storage box 7 to the collection pipe 9. The collection pipe 9 is used to distribute the coolant evenly to multiple inlet pipes 5, and the inlet pipes 5 further transport the coolant to multiple cooling pipes 4. In this way, the coolant in the storage box 7 can be quickly and evenly distributed to multiple sets of cooling pipes 4. The coolant in the cooling pipes 4 is used to absorb the heat generated by the copper busbar 2 during operation, so that the heat can be carried away with the flow of coolant, thereby reducing the temperature of the copper busbar 2 during operation.

[0036] Furthermore, cooling pipes 4 are arranged on the side of adjacent copper busbars 2, and multiple sets are provided to ensure the uniformity and sufficiency of cooling treatment of copper busbars 2, and to ensure the stable long-term operation of copper busbars 2. After heat is absorbed inside the cooling pipes 4, the coolant carrying the heat is returned to the storage box 7 through the return pipe 6. When the coolant returns through the return pipe 6, the metal heat-conducting strip 11 is used to enable the heat dissipated outside the return pipe 6 to be quickly dissipated through the metal heat-conducting strip 11 during the process of the return pipe 6 carrying the coolant back, thereby making the temperature of the coolant returning in the return pipe 6 lower.

[0037] After the coolant flows back into the reservoir 7, the heat dissipation fins 10 on the side of the reservoir 7 can conduct and dissipate the heat as the coolant carrying heat flows back into the reservoir 7. Combined with the heat dissipation grooves 15 in the back shell 14, the heat can be quickly radiated and dissipated, reducing the internal temperature of the reservoir 7. In this way, the coolant can be circulated for cooling and ensure the continuous cooling effect of the cooling pipe 4 on the copper busbar 2.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
