Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar with internal and external heat dissipation. Background Technology

[0002] Busbar trunking, as a highly efficient power transmission device, is widely used in modern buildings, factories, and data centers. With the continuous increase in electrical load, busbar trunking generates a significant amount of Joule heat during operation. If this heat cannot be dissipated in time, it will cause the conductor temperature to rise and the resistance to increase, creating a vicious cycle. This not only reduces power transmission efficiency but also accelerates the aging of insulation materials and may even lead to safety accidents such as fires.

[0003] Existing busbar cooling methods mostly rely on natural air cooling or simple heat dissipation fins on the outer casing, resulting in limited heat dissipation efficiency. For densely packed conductors inside, especially multiphase conductors, the heat generated is difficult to conduct quickly to the outer casing and dissipate into the surrounding environment, leading to heat accumulation and the formation of localized hot spots, posing a threat to the safe operation of the system. To address this issue, we propose a busbar with internal and external heat dissipation to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a busbar trunking with internal and external heat dissipation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a busbar trunking system with internal and external heat dissipation, comprising: The busbar trunking body has a trunking cover fixedly installed at its top with multiple bolts. Air guide covers are welded to the inner walls of both the bottom side of the busbar trunking body and the inner walls of the trunking cover. One end of each air guide cover is open. Two air vents are located on the bottom wall of the top side of the air guide cover away from the opening, and plug-in sleeves are welded to each of the two air vents. Two air guide pipes are welded to the top wall of the bottom side of the air guide cover away from the opening, and the two air guide pipes are movably inserted into the two plug-in sleeves. A ventilation opening is located on the bottom wall of the busbar trunking body, at the end away from the opening of the air guide cover. An exhaust fan is fixedly installed inside the exhaust fan, and an L-shaped exhaust pipe is fixedly installed on the exhaust fan.

[0006] Preferably, multiple equidistant heat sinks are fixedly welded to the outer walls of both the busbar trunking body and the trunking cover, and the heat sinks are made of aluminum.

[0007] Preferably, a temperature control switch is installed in the inner cavity of the busbar trunking body, and the temperature control switch is electrically connected to the axial flow fan in the exhaust duct.

[0008] Preferably, dustproof nets are fixedly installed at the openings of both the vent and the L-shaped exhaust pipe.

[0009] Preferably, the vent is located at the end away from the opening of the air guide cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention monitors the temperature of the inner cavity of the busbar trunking body using a temperature control switch. When the temperature of the inner cavity reaches the set maximum threshold, the axial flow fan is activated, allowing outside air to enter the inner cavity of the busbar trunking body through the ventilation opening. The airflow carries away heat as it passes through the entire inner cavity of the busbar trunking body. The heated air enters through the air guide cover opening and is discharged through the L-shaped exhaust pipe. As the heat flows through the inner cavity of the air guide pipe, it is conducted to the bottom wall and the cover of the busbar trunking body, where it is dissipated through multiple heat sinks. This achieves combined internal and external heat dissipation of the busbar trunking, resulting in not only good heat dissipation but also more uniform heat dissipation, ensuring the stable operation of the busbar trunking.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a busbar trunking with internal and external heat dissipation, comprising: The busbar trunking body 1 has a trunking cover 2 fixedly installed at its top end by multiple bolts. Air guide covers 3 are fixedly welded to the inner walls of both the bottom side of the busbar trunking body 1 and the inner walls of the trunking cover 2. One end of the air guide cover 3 is open. Two air guide ports 4 are opened on the bottom wall of the top side of the air guide cover 3 away from the opening. Insertion sleeves 5 are fixedly welded to each of the two air guide ports 4. Two air guide pipes 6 are fixedly welded to the top wall of the bottom side of the air guide cover 3 away from the opening. The two air guide pipes 6 are movably inserted into the two insertion sleeves 5. A ventilation opening 7 is opened on the bottom wall of the busbar trunking body 1, located at the end away from the opening of the air guide cover 3. An exhaust duct 8 is fixedly installed on the trunking cover 2, and an axial flow fan is fixedly installed inside the exhaust duct 8. An L-shaped exhaust pipe 9 is fixedly installed on the exhaust duct 8.

[0015] Multiple heat sinks 10 are fixedly welded to the outer walls of the busbar trunking body 1 and the trunking cover 2. The heat sinks 10 are made of aluminum, which is lightweight and has good thermal conductivity. This increases the contact area between heat and air on the busbar trunking body 1 and the trunking cover 2, thereby improving the heat dissipation effect.

[0016] A temperature control switch 11 is installed in the inner cavity of the bus trunking body 1. The temperature control switch 11 is electrically connected to the axial flow fan in the exhaust duct 8. The temperature control switch 11 can monitor the temperature of the inner cavity of the bus trunking body 1. When the temperature of the inner cavity of the bus trunking body 1 reaches the set maximum threshold, the axial flow fan will be turned on. When the temperature of the inner cavity of the bus trunking body 1 reaches the set minimum threshold, the axial flow fan will be automatically turned off.

[0017] Dustproof nets 12 are fixedly installed at the openings of the ventilation vent 7 and the L-shaped exhaust pipe 9 to prevent dust and impurities from entering the inner cavity of the busbar trunking.

[0018] The ventilation opening 7 is located at the end away from the opening of the air guide cover 3. Outside air can enter the inner cavity of the busbar trunking body 1 through the ventilation opening 7, and flow through the entire inner cavity of the busbar trunking body 1 with the airflow to enter the opening of the air guide cover 3, making the heat dissipation more uniform.

[0019] Working principle: This utility model monitors the temperature inside the busbar trunking body 1 using a temperature control switch 11. When the temperature inside the busbar trunking body 1 reaches the set maximum threshold, the axial flow fan is activated, allowing outside air to enter the inside of the busbar trunking body 1 through the ventilation port 7. The airflow carries away heat as it passes through the entire inside of the busbar trunking body 1. The heated air enters through the opening of the air guide cover 3 and is discharged through the L-shaped exhaust pipe 9. As the heat flows through the inside of the air guide pipe 3, it is conducted to the bottom wall of the busbar trunking body 1 and the trunking cover 2, where it is dissipated through multiple heat sinks 10. This achieves combined internal and external heat dissipation of the busbar trunking, resulting in better and more uniform heat dissipation and ensuring the stable operation of the busbar trunking.
