Description

Technical Field

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

[0002] With the increasing application of busbar trunking in construction, its safety has become a growing concern. Due to the resistance and impedance of the conductors, heat is generated during the energization of the busbar trunking. The temperature of various parts of the busbar trunking gradually rises. If the heat is not dissipated in time, the overall temperature rise of the busbar will increase, leading to increased power loss, accelerated aging of insulation materials, a rapid shortening of the service life of the busbar trunking, and even short circuit accidents.

[0003] Traditional busbar trunking relies primarily on its outer casing for heat dissipation, which is not ideal and cannot achieve rapid heat dissipation. Therefore, this invention proposes a high-efficiency heat-dissipating busbar trunking to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a high-efficiency heat-dissipating busbar trunking. Through the heat dissipation channels of the first, second, and third heat dissipation components, heat on the intermediate I-beam, the first side plate, and the second side plate can be discharged from the heat dissipation channels, thereby achieving rapid heat dissipation. The cross-bracing structure ensures the heat dissipation capacity of the heat dissipation channels while also ensuring the structural strength and stability of the intermediate I-beam, the first side plate, and the second side plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The first, second, and third heat dissipation components have the same structure, each including a heat dissipation channel and a cross inner support frame, and the cross inner support frame is detachably installed inside the heat dissipation channel.

[0008] A further improvement is that the multiple heat dissipation channels on the first side plate and the multiple heat dissipation channels on the second side plate are staggered, and the size of the heat dissipation channel on the intermediate I-beam frame is larger than the size of the heat dissipation channel on the first side plate and the second side plate.

[0009] A further improvement is that: slots are provided at the four corners of the heat dissipation channel, the slots are connected to the heat dissipation channel, and blocks are provided at the four corners of the cross inner support, the blocks are adapted to the slots for installation.

[0019] To deepen the understanding of this utility model, the following detailed description of the utility model will be provided in conjunction with the embodiments. These embodiments are only used to explain the utility model and do not constitute a limitation on the scope of protection of the utility model.

[0020] according to Figure 1-4 As shown, this embodiment proposes a high-efficiency heat-dissipating busbar trunking, including a top plate 1, a bottom plate 2, a middle I-beam frame 3, and a heat dissipation structure. The top plate 1 and the bottom plate 2 are opposite each other, and the middle I-beam frame 3 is provided between the top plate 1 and the bottom plate 2. The middle I-beam frame 3 is symmetrically provided with first side plates 4 on both sides, and each of the two first side plates 4 is provided with a second side plate 5 on one side. The upper ends of the first side plates 4 and the second side plates 5 are connected to the middle I-beam frame 3 at their lower ends. The heat dissipation structure includes a first heat dissipation component 6, a second heat dissipation component 7, and a third heat dissipation component 8. The first heat dissipation component 6 is provided on the middle I-beam frame 3, the second heat dissipation component 7 is provided on the first side plate 4, and the third heat dissipation component 8 is provided on the second side plate 5. Multiple sets of the first heat dissipation component 6, the second heat dissipation component 7, and the third heat dissipation component 8 are provided. The first heat dissipation component 6, the second heat dissipation component 7, and the third heat dissipation component 8 have the same structure, each including a heat dissipation channel 9 and a cross inner support frame 10. The cross inner support frame 10 is detachably installed in the heat dissipation channel 9.

[0021] In this utility model, the cavity between the intermediate I-beam 3 and the first side plate 4 and the second side plate 5 of the busbar trunking contains L1-phase busbar, L2-phase busbar, L3-phase busbar and N-phase busbar respectively. When the busbar trunking of this utility model dissipates heat during operation, the heat transferred to the intermediate I-beam 3, the first side plate 4 and the second side plate 5 will be discharged from the heat dissipation channel 9, which avoids the heat from accumulating on the intermediate I-beam 3, the first side plate 4 and the second side plate 5 for a long time, and also avoids the heat from being transferred from the intermediate I-beam 3 to the top plate 1 and the bottom plate 2, which would cause poor heat dissipation of the entire busbar trunking structure.

[0022] The multiple sets of heat dissipation channels 9 on the first side plate 4 and the multiple sets of heat dissipation channels 9 on the second side plate 5 are staggered. The size of the heat dissipation channel 9 on the intermediate I-beam 3 is larger than the size of the heat dissipation channel on the first side plate 4 and the second side plate 5. This arrangement can improve the structural stability of the entire busbar trunking and avoid a decrease in the structural strength of the busbar trunking at the location of the heat dissipation channel 9 due to the same location of the heat dissipation channel 9.

[0023] The heat dissipation channel 9 has slots 11 at its four corners, which communicate with the heat dissipation channel 9. The cross inner support frame 10 has blocks 12 at its four corners, which are fitted and installed in accordance with the slots 11. This design allows for quick assembly of the cross inner support frame 10, and the cross inner support frame 10 improves the structural stability of the busbar trunking, preventing a decrease in structural strength due to the heat dissipation channel 9.

[0024] An aluminum alloy heat sink 13 is provided on the outer wall of the second side plate 5. Multiple sets of the aluminum alloy heat sink 13 are provided, and each set is wavy with an arched middle section. The aluminum alloy heat sink 13 can quickly conduct heat from the second side plate 5 and dissipate heat through convection with the air.

[0025] The second side plate 5 has heat dissipation grooves 14 on one side wall. The number of heat dissipation grooves 14 is adapted to the number of heat dissipation channels 9 of the third heat dissipation component 8, and the heat dissipation grooves 14 are connected to the heat dissipation channels 9 of the third heat dissipation component 8. By setting the heat dissipation grooves 14, the heat dissipation in the heat dissipation channels 9 can be further accelerated.

[0026] The aluminum alloy heat sink 13 is provided with cooling water tanks 15 at both the top and bottom, and the shape of the cooling water tanks 15 is adapted to the form of the aluminum alloy heat sink 13. The cooling water tanks 15 enable the aluminum alloy heat sink 13 to be rapidly cooled and dissipated using cooling water.

[0027] This utility model provides a first heat dissipation component 6 on the intermediate I-beam 3, a second heat dissipation component 7 on the first side plate 4, and a third heat dissipation component 8 on the second side plate 5. The first heat dissipation component 6, the second heat dissipation component 7, and the third heat dissipation component 8 have the same structure, all consisting of a heat dissipation channel 9 and a cross inner support frame 10. The heat dissipation channel 9 can dissipate heat from the intermediate I-beam 3, the first side plate 4, and the second side plate 5 through the heat dissipation channel 9, thereby achieving rapid heat dissipation. The cross inner support frame 10 ensures the heat dissipation capacity of the heat dissipation channel 9 while also ensuring the structural strength and stability of the intermediate I-beam 3, the first side plate 4, and the second side plate 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
