Description

Technical Field

[0001] This utility model relates to the field of busbar bridge technology, and more specifically, to a closed busbar bridge. Background Technology

[0002] A busbar bridge is an electrical connection device based on bridge wiring. Its core function is to electrically connect two power supply lines and two transformers through a jumper circuit breaker (BCD) to form a simplified main wiring structure. Depending on the location of the circuit breaker, busbar bridges can be divided into internal wiring bridges suitable for long lines and stable load scenarios, and external wiring bridges suitable for short lines and large load fluctuation scenarios. In some specific scenarios, enclosed busbar bridges are required.

[0003] For example, patent number CN219627324U discloses a closed high-voltage busbar bridge, including a bridge body and a three-phase copper busbar installed inside the bridge body. One end of the bridge body is a bridge head, which is a flared opening. The three-phase copper busbar inside the flared opening is used to connect to an external high-voltage power supply. A movable cover plate is hinged to the upper part of the bridge head and fixed to the upper part of the bridge head by a buckle. A pressure relief cover a is hinged to the movable cover plate. The three-phase copper busbar inside the other end of the bridge body is connected to a high-voltage cabinet. A pressure relief cover b is hinged to the upper part of the other end of the bridge body. Observation windows are provided at the lower part of the bridge body.

[0004] For example, patent number CN223285550U discloses a busbar bridge that is easy to disassemble and maintain, including a first cable tray side plate, a second cable tray side plate is provided on one side of the first cable tray side plate, a bottom plate is provided at the bottom of the first and second cable tray side plates, a fixing screw is provided through the bottom plate and the top plate, a triangular connector is provided at one end of the bottom plate and the top plate, a connecting plate is provided on the triangular connector, a fixing bolt is provided through the connecting plate and extends to the side wall of the first and second cable tray side plates.

[0005] However, in actual use, since the busbar bridge is in a closed state, its overall heat dissipation relies solely on a single heat sink structure. However, the heat sink has a limited heat dissipation speed and cannot accelerate the air flow rate inside and outside the heat sink as needed. This results in an inability to accelerate the dissipation of heat from the heat sink, and consequently, an inability to accelerate the absorption of heat from the busbar bridge. Consequently, the heat dissipation effect of the busbar bridge is poor, which in turn directly affects the normal operation of the internal equipment and poses a significant safety hazard. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a closed bus bridge to solve the problem that the prior art cannot accelerate the gas flow rate inside and outside the heat sink as needed, which leads to the inability to accelerate the heat dissipation rate on the heat sink and thus the inability to accelerate the heat absorption rate of the heat sink inside the bus bridge, resulting in poor heat dissipation effect of the bus bridge.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a closed busbar bridge, including a busbar bridge body, wherein multiple sets of U-shaped heat dissipation plates with gradually decreasing overall size are embedded in the front and back of the busbar bridge body from top to bottom, a suspension bracket is fixed at the bottom of the busbar bridge body, a controller is fixed at the bottom of the suspension bracket, and auxiliary heat dissipation components that cooperate with the U-shaped heat dissipation plates are provided on the suspension bracket and the busbar bridge body.

[0008] The auxiliary heat dissipation assembly includes cavities formed within each group of U-shaped heat dissipation plates. One end of each group of U-shaped heat dissipation plates is connected to a first pipe that communicates with the cavity, and the other end of each group of U-shaped heat dissipation plates is connected to a second pipe that communicates with the cavity. An air pump and a cooler are sequentially fixed within the suspension frame along the left-right direction. The air outlet of the air pump is connected to a T-connector. The two ends of the T-connector away from the air pump are respectively connected to a first connecting frame and a second connecting frame along the left-right direction. The end of the first pipe away from the U-shaped heat dissipation plate is connected to the second connecting frame, and the end of the second pipe away from the U-shaped heat dissipation plate is connected to the first connecting frame. The air outlet of the air pump and the air inlet of the cooler are interconnected. Multiple sets of blowing pipes that cooperate with the U-shaped heat dissipation plates are sequentially fixed along the vertical direction of the first connecting frame. Each set of second pipes is equipped with an auxiliary one-way valve.

[0009] Among them, an auxiliary heat dissipation plate is fixed on the side of the adjacent U-shaped heat dissipation plates that are close to each other. The auxiliary heat dissipation plate has a U-shaped structure. Multiple sets of ventilation holes are evenly opened on each set of auxiliary heat dissipation plates. A reinforcing bend is provided on the side of the adjacent two sets of first pipes that are close to each other. One end of the reinforcing bend is connected to the second connecting frame. The end of the reinforcing bend away from the second connecting frame extends to the inside of the auxiliary heat dissipation plate.

[0010] There is a gap between the first connecting frame and the second connecting frame and the bottom mounting frame of the busbar bridge body.

[0011] The number of U-shaped heat dissipation plates on the front and back of the bus bridge body is at least three.

[0012] The first connecting frame is fixed at both ends away from the tee pipe on the left side of the front and back top of the busbar bridge body.

[0013] Each of the blowing pipes in the group has an inwardly inclined structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, by setting up auxiliary heat dissipation components, using a cooler and an air pump, cool air below room temperature can be rapidly circulated within the cavity of the U-shaped heat sink. The airflow can simultaneously accelerate the gas flow rate inside the U-shaped heat sink, quickly carrying heat away from the cavity and simultaneously cooling the entire interior of the U-shaped heat sink. This allows for simultaneous cooling of the busbar bridge body. Furthermore, multi-directional blowing on the surface of the U-shaped heat sink accelerates the gas flow rate, simultaneously increasing the dissipation rate of heat absorbed on the U-shaped heat sink from both inside and outside. This allows for better and faster heat conduction and dissipation, facilitating faster heat absorption within the busbar bridge body, improving the overall heat dissipation speed of the busbar bridge body, and preventing overheating that could affect the normal operation of the internal equipment.

Detailed Implementation

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 4This utility model provides a technical solution: a closed busbar bridge, including a busbar bridge body 1. Multiple sets of U-shaped heat dissipation plates 3, with gradually decreasing overall dimensions, are sequentially embedded on the front and back of the busbar bridge body 1 from top to bottom. The number of U-shaped heat dissipation plates 3 on both the front and back of the busbar bridge body 1 is at least three sets. This limitation on the number of U-shaped heat dissipation plates 3 is to further improve the heat absorption rate inside the busbar bridge body 1 and enhance its heat dissipation effect. A suspension bracket 2 is fixed to the bottom of the busbar bridge body 1, and a controller is fixed to the bottom of the suspension bracket 2. The hanger 2 and the busbar bridge body 1 are equipped with auxiliary heat dissipation components that work in conjunction with U-shaped heat dissipation plates 3. The auxiliary heat dissipation components include cavities 4 formed in each group of U-shaped heat dissipation plates 3. One end of each group of U-shaped heat dissipation plates 3 is connected to a first pipe 10 that communicates with the cavity 4, and the other end of each group of U-shaped heat dissipation plates 3 is connected to a second pipe 11 that communicates with the cavity 4. An air pump 5 and a cooler 6 are fixed sequentially in the left-right direction inside the hanger 2. The air outlet of the air pump 5 is connected to a three-way pipe 7, and the two ends of the three-way pipe 7 away from the air pump 5 are respectively connected to the left-right direction. There are a first connecting frame 8 and a second connecting frame 9. Both the first connecting frame 8 and the second connecting frame 9 have gaps between them and the bottom mounting frame of the busbar bridge body 1. The gaps are designed to prevent the first connecting frame 8 and the second connecting frame 9 from interfering with the normal installation of the busbar bridge body 1, facilitating quick assembly of the busbar bridge body 1. The end of the first pipe 10 furthest from the U-shaped heat sink 3 is connected to the second connecting frame 9, and the end of the second pipe 11 furthest from the U-shaped heat sink 3 is connected to the first connecting frame 8. The air outlet of the air pump 5 and the air inlet of the air conditioner 6 are interconnected. The vertical end of the frame 8 is fixed with multiple sets of blowing pipes 13 that work with the U-shaped heat sink 3. Each set of blowing pipes 13 has an inwardly inclined structure so that the blowing pipes 13 can blow on the surface of the U-shaped heat sink 3 over a wide area, further accelerating the heat dissipation speed of the U-shaped heat sink 3. Each set of second pipes 11 is equipped with an auxiliary one-way valve 12. The two ends of the first connecting frame 8 away from the three-way pipe 7 are fixed on the left side of the front and back top of the busbar bridge body 1, which improves the overall stability of the first connecting frame 8 and avoids shaking and easy breakage.

[0024] By setting up auxiliary heat dissipation components, using the air cooler 6 and the air pump 5, cool air below room temperature can be rapidly circulated within the cavity 4 of the U-shaped heat sink 3. Simultaneously, the first connecting frame 8 guides the gas flow, creating a negative pressure at the second pipe 11 to simultaneously accelerate the gas flow rate inside the U-shaped heat sink 3, quickly carrying heat away from the cavity 4. This also simultaneously cools the entire interior of the U-shaped heat sink 3, thereby simultaneously cooling the interior of the busbar bridge body 1, further improving the cooling speed of the busbar bridge body 1. Furthermore, multiple sets of blowing pipes 13 can blow air in multiple directions onto the surface of the U-shaped heat sink 3, accelerating the gas flow rate on the surface of the U-shaped heat sink 3, thus simultaneously accelerating the dissipation of heat absorbed on the U-shaped heat sink 3 from both inside and outside. This allows the U-shaped heat sink 3 to conduct and dissipate heat better and faster, facilitating faster heat absorption within the busbar bridge body 1, improving the overall heat dissipation speed of the busbar bridge body 1, and preventing overheating inside the busbar bridge body 1 from affecting the normal operation of the internal equipment.

[0025] Example 2: Based on Example 1, in order to further accelerate the heat absorption and conduction speed of the U-shaped heat sink 3 and accelerate the cooling speed of the bus bridge body 1, it is necessary to expand the heat conduction area of ​​the U-shaped heat sink 3. An auxiliary heat sink 15 is fixed on the side of the adjacent U-shaped heat sink 3 that is close to each other. The auxiliary heat sink 15 has a U-shaped structure. Multiple sets of vent holes 16 are evenly opened on each set of auxiliary heat sink 15. A reinforcing bend 14 is provided on the side of the adjacent two sets of first pipes 10 that are close to each other. One end of the reinforcing bend 14 is connected to the second connecting frame 9. The end of the reinforcing bend 14 away from the second connecting frame 9 extends to the inside of the auxiliary heat sink 15.

[0026] By utilizing the auxiliary heat dissipation plate 15 and in conjunction with multiple sets of vent holes 16, the overall heat dissipation area of ​​the U-shaped heat dissipation plate 3 can be further expanded. Furthermore, the reinforced bend 14 can guide the gas flow within the second connecting frame 9, thereby accelerating the gas flow rate on the auxiliary heat dissipation plate 15 and further accelerating the heat dissipation rate on the U-shaped heat dissipation plate 3. This improves the heat absorption and heat conduction efficiency of the U-shaped heat dissipation plate 3, thereby enhancing the cooling speed and effect of the busbar bridge body 1.

[0027] The working process of this utility model is as follows:

[0028] When the busbar bridge body 1 is in use, high temperatures are generated inside. At this time, the U-shaped heat sink 3 can absorb the heat inside the busbar bridge body 1 and conduct it to the outside. At this time, the controller turns on the air cooler 6 and the air pump 5. The air cooler 6 delivers air below room temperature to the three-way pipe 7 via the air pump 5, and then to the first connecting frame 8 and the second connecting frame 9 via the three-way pipe 7. At the same time, the second connecting frame 9 delivers air to the cavity 4 of the U-shaped heat sink 3 via the first pipe 10. At this time, the air below room temperature can accelerate the air flow rate inside the U-shaped heat sink 3, quickly remove the heat from the cavity 4, and simultaneously cool the entire interior of the U-shaped heat sink 3. This allows the busbar bridge body 1 to be cooled synchronously, enabling the U-shaped heat sink 3 to absorb more heat. At the same time, the second connecting frame 9 can simultaneously deliver air below room temperature to the inside of the auxiliary heat sink 15 via the reinforced bend pipe 14, thereby accelerating the air flow rate on the auxiliary heat sink 15 and further accelerating the heat dissipation on the U-shaped heat sink 3. The first connecting frame 8 can guide some of the gas below room temperature, and the gas flow rate in the first connecting frame 8 is greater than the gas flow rate in the cavity 4. At this time, the flow rate difference can be used to form a negative pressure state at the second pipe 11, which can accelerate the movement speed of the gas in the cavity 4, thereby quickly removing the heat from the U-shaped heat sink 3 and increasing the heat dissipation speed inside the U-shaped heat sink 3. At the same time, the gas that has been fused with a certain amount of heat and heated up can be neutralized with the gas below room temperature in the first connecting frame 8, so that the gas returns to a low temperature state. The gas is then blown in multiple directions on the surface of the U-shaped heat sink 3 and the auxiliary heat sink 15 through multiple sets of blowing pipes 13, which accelerates the gas flow rate on the surface of the U-shaped heat sink 3 and the auxiliary heat sink 15, thereby accelerating the heat dissipation speed on the U-shaped heat sink 3 and the auxiliary heat sink 15, thus accelerating the absorption speed of heat in the bus bridge body 1 by the U-shaped heat sink 3, and thus improving the overall heat dissipation speed of the bus bridge body 1.

[0029] Compared to the prior art and common existing technologies, no auxiliary heat dissipation structure is added to the busbar bridge body 1. In actual use, both ends of the busbar bridge body 1 are connected to the equipment, and the interior of the busbar bridge body 1 is in a relatively closed state. The overall heat dissipation method of the traditional busbar bridge body 1 mostly relies on a single fixed heat sink structure or heat dissipation hole structure. However, the heat dissipation speed of this method is very limited, and it cannot accelerate the air flow rate inside and outside the traditional fixed heat sink, thus failing to accelerate the heat dissipation speed of the traditional fixed heat sink. Consequently, it cannot promote the fixed heat sink to quickly absorb the heat inside the busbar bridge body 1, which directly leads to poor heat dissipation effect of the busbar bridge body 1. The internal temperature cannot be reduced quickly, making the internal equipment prone to malfunction due to high temperature, and also posing significant safety hazards such as overheating short circuits or fires. This application utilizes an auxiliary heat dissipation component to simultaneously accelerate the dissipation of heat absorbed on the U-shaped heat sink 3 from both inside and outside, so that the U-shaped heat sink 3 can conduct and dissipate heat better and faster. This facilitates faster heat absorption within the busbar bridge body 1, improves the overall heat dissipation speed of the busbar bridge body 1, and prevents overheating of the busbar bridge body 1 from affecting the normal operation of the internal equipment. Compared with the prior art, this application has a faster cooling speed, ensuring the long-term operation of the internal equipment of the busbar bridge body 1, and has a low failure rate.
