Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar with a heat dissipation structure. Background Technology

[0002] Busbar trunking is an enclosed metal device consisting of an aluminum cover plate and copper / aluminum busbars. It is often used in power transmission projects to replace electric wires and cables.

[0003] Existing busbar trunking systems dissipate heat through U-shaped side plates installed on both sides of the cover plate. However, since the busbar trunking generates a certain temperature when energized, the U-shaped side plates alone are insufficient for effective heat dissipation, especially for densely packed busbars where heat from the busbar in the middle is difficult to transfer through the side plates. Therefore, this invention proposes a busbar trunking system with a heat dissipation structure that improves heat dissipation without compromising the stability of the cover plate and U-shaped side plates. Utility Model Content

A first busbar and a second busbar are provided on the inner side of the left U-shaped side plate and the first busbar is attached to the left U-shaped side plate, and the second busbar is attached to the right U-shaped side plate. The feature is that a heat dissipation plate is provided on the side of the first busbar away from the left U-shaped side plate and the side of the second busbar away from the right U-shaped side plate. The heat dissipation plate includes a heat-conducting part and a heat dissipation part fixedly connected to one end of the heat-conducting part. The heat-conducting part is attached to the first busbar or the second busbar, and the heat dissipation part is attached to the left U-shaped side plate or the right U-shaped side plate. The length of the heat dissipation part is 1.5 to 1.8 times the shorter side of the left U-shaped side plate and the right U-shaped side plate.

[0006] Furthermore, the upper and lower cover plates are fitted to the heat dissipation section of the heat sink.

[0007] Furthermore, the heat sink is an L-shaped heat sink, with the heat dissipation part perpendicular to the heat conduction part.

[0009] Furthermore, the heat-conducting part is attached to the first busbar or the second busbar, and the heat-dissipating parts on the four L-shaped heat sinks are divided into two groups and attached to the left U-shaped side plate and the right U-shaped side plate respectively.

[0010] Furthermore, the heat sink is a U-shaped heat sink, with the heat dissipation part perpendicular to the heat conduction part.

[0011] Furthermore, at least two U-shaped heat sinks are provided. One U-shaped heat sink is provided on the side of the first busbar away from the left U-shaped side plate, and one U-shaped heat sink is provided on the side of the second busbar away from the right U-shaped side plate.

[0016] In this invention, a heat dissipation plate is installed to cool the inside of the busbar trunking, preventing the busbar temperature from becoming too high and reducing potential safety hazards.

[0021] This application discloses a busbar trunking with a heat dissipation structure, as shown in the embodiments below. Figure 1 It includes an upper cover plate 1, a lower cover plate 2 symmetrically arranged with respect to the upper cover plate 1, and a left U-shaped side plate 3 and a right U-shaped side plate 4 symmetrically arranged on the left and right sides. A first busbar 5 and a second busbar 6 are provided on the inner sides of the left U-shaped side plate 3 and the right U-shaped side plate 4, respectively. The first busbar 5 is fitted with the left U-shaped side plate 3, and the second busbar 6 is fitted with the right U-shaped side plate 4. The upper cover plate 1 and the lower cover plate 2 are H-shaped covers.

[0022] Example 1:

[0023] Reference Figure 1 and Figure 2 The first busbar 5 has two L-shaped heat dissipation plates on the side away from the left U-shaped side plate 3, and the second busbar 6 has two L-shaped heat dissipation plates on the side away from the right U-shaped side plate 4. The four L-shaped heat dissipation plates 7 are arranged symmetrically in the vertical and horizontal directions. Each L-shaped heat dissipation plate 7 includes a heat-conducting part 72 and a heat dissipation part 71 fixedly connected to one end of the heat-conducting part. The heat dissipation part 71 is perpendicular to the heat-conducting part 72. The heat-conducting part 72 is attached to the first busbar 5 or the second busbar 6. The heat dissipation parts 71 on the four L-shaped heat dissipation plates 7 are evenly divided into two groups and attached to the left U-shaped side plate 3 and the right U-shaped side plate 4 respectively. On the U-shaped side plate 4, the upper cover plate 1 and upper cover plate 2 are also attached to the heat dissipation part 71. The heat conduction part 72 can transfer the heat generated by the first busbar 5 and the second busbar 6 to the heat dissipation part 71. The heat dissipation part 71 can transfer the heat to the left U-shaped side plate 3, the right U-shaped side plate 4, and the upper cover plate 1 and upper cover plate 2 respectively, and then dissipate it through the left U-shaped side plate 3, the right U-shaped side plate 4, and the upper cover plate 1 and upper cover plate 2, thereby achieving the purpose of cooling the inside of the busbar trunking, preventing the busbar temperature from becoming too high, and reducing the safety hazards of the busbar trunking. At the same time, the heat dissipation part 71 of the L-shaped heat dissipation plate 7 is attached parallel to the left U-shaped side plate 3, the right U-shaped side plate 4, and the upper cover plate 1 and upper cover plate 2 respectively, which can increase the contact area between the L-shaped heat dissipation plate 7 and the left U-shaped side plate 3, the right U-shaped side plate 4, and the upper cover plate 1 and upper cover plate 2, further improving the heat dissipation effect.

[0024] Reference Figure 1 The length of the heat dissipation section 71 of the four L-shaped heat sinks 7 is 1.5 to 1.8 times the short side of the left U-shaped side plate 3 and the right U-shaped side plate 4, so that part of the heat dissipation section 71 is exposed outside the short side of the left and right U-shaped side plates, further improving the heat dissipation effect. The upper cover plate 1 and the upper cover plate 2 are attached to the heat dissipation section 71 of the L-shaped heat sink 7, and the left U-shaped side plate 3 and the right U-shaped side plate 4 are attached to the heat dissipation section 71 of the L-shaped heat sink 7, enhancing the stability of the left and right U-shaped side plates and the upper and lower cover plates.

[0025] Example 2:

[0026] Reference Figure 3 and Figure 4 This embodiment discloses another U-shaped heat sink distribution method: a U-shaped heat sink is provided on the side of the first busbar 5 away from the left U-shaped side plate 3, and a U-shaped heat sink is provided on the side of the second busbar 6 away from the right U-shaped side plate 4. The two U-shaped heat sinks 8 are arranged symmetrically on the left and right.

[0027] The U-shaped heat sink 8 includes a heat dissipation section 81, a heat dissipation section 83, and a heat conduction section 82. The heat dissipation sections 81 and 83 are perpendicular to the heat conduction section 82. The heat conduction section 82 is attached to the first busbar 5 or the second busbar 6. The heat dissipation sections 81 and 83 on the U-shaped heat sink 8 are respectively attached to the U-shaped side plate 3 and the U-shaped side plate 4. The upper cover plate 1 and the upper cover plate 2 are respectively attached to the heat dissipation sections 81 and 83. The heat conduction section 82 can dissipate heat from the first busbar 5 and the second busbar 6. The heat generated by 6 is transferred to the heat dissipation parts 81 and 83. The heat dissipation parts 81 and 83 can transfer the heat to the left U-shaped side plate 3, the right U-shaped side plate 4, the top cover plate 1 and the top cover plate 2 respectively, and then dissipate it through the left U-shaped side plate 3, the right U-shaped side plate 4, the top cover plate 1 and the top cover plate 2. At the same time, the heat dissipation parts 81 and 83 of the U-shaped heat dissipation plate 8 are parallel and attached to the left U-shaped side plate 3, the right U-shaped side plate 4, the top cover plate 1 and the top cover plate 2 respectively.

[0028] The arrangement of two U-shaped heat sinks 8 can increase the connection stability between the heat sink and the upper cover plate 1 and the upper cover plate 2, and between the heat sink and the left U-shaped side plate 3 and the right U-shaped side plate 4, further ensuring the heat dissipation effect.

[0029] In the above embodiments, the heat sink is an aluminum plate.
