[0019] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0020] A bus duct of a connector with a heat dissipation device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example

[0022] For easier understanding, see Figures 1 to 3The utility model provides an embodiment of a bus duct of a connector with a heat dissipation device, comprising a bus duct body 1, a plurality of heat dissipation devices 3 are arranged on the inner side of the bus duct body 1, and a plurality of bus bodies 2 are arranged on both sides of the heat dissipation device 3, the heat dissipation device 3 comprises a plurality of heat dissipation frames 31, heat dissipation strips 32, corrugated fins 33 and pin-shaped fins 34, a plurality of the heat dissipation strips 32 are fixedly connected to the two side walls of the heat dissipation frame 31, and the heat dissipation frame 31 has three ventilation ducts inside, a plurality of the corrugated fins 33 are respectively fixedly connected to the three ventilation ducts in the heat dissipation frame 31, and a plurality of the pin-shaped fins 34 are fixedly connected to the end faces of the corrugated fins 33.

[0023] It should be noted that the heat dissipation devices 3 are located on both sides of the busbar body 2 to ensure effective conduction and dissipation of heat.

[0024] The heat dissipation device 3 is composed of a heat dissipation frame 31, heat dissipation strips 32, corrugated fins 33 and pin-shaped fins 34. Three ventilation ducts are designed inside the heat dissipation frame 31 to promote air flow. The heat dissipation strips 32 are fixed to the two side walls of the heat dissipation frame to increase the strength and thermal conductivity of the overall structure. The corrugated fins 33 not only improve the corrosion resistance of the fins, but also increase the surface area, which is beneficial to heat radiation. The corrugated fins 33 and the pin-shaped fins 34 are respectively fixed in three ventilation ducts, further optimizing the airflow channel. The pin-shaped fins 34 are fixed on the end face of the corrugated fins, and the heat dissipation area is increased through their slender structure, thereby enhancing the convection heat dissipation effect.

[0025] Among them, the pin-shaped fins 34 are made of composite fin materials, and the composite fin materials are composed of metal (such as copper) and ceramics or carbon-based materials with high thermal conductivity (such as carbon fiber) to form a composite structure, which not only ensures high thermal conductivity but also reduces weight. A hollow heat dissipation hole can be provided at one end of the bus duct body 1, and a better heat dissipation effect can be achieved by using the heat dissipation hole.

[0026] In an optional embodiment: a connecting member 4 is fixedly connected between the two heat dissipation devices 3 in the vertical direction, and the interior of the connecting member 4 is hollow.

[0027] It should be noted that two adjacent heat dissipation devices 3 are fixedly connected via a connector 4 . The interior of the connector 4 is hollow, which not only plays a structural connection role, but also helps to form an air flow path to enhance the heat dissipation effect.

[0028] In an optional embodiment: a supporting bar 5 is fixedly connected to one side of the bus duct body 1 , and the supporting bar 5 is supported on one side of the busbar body 2 .

[0029] It should be noted that a support bar 5 is installed on one side of the bus duct body 1 to provide a stable lateral support for the bus body 2 to avoid deformation caused by gravity or external force.

[0030] In an optional embodiment: a mounting bolt 6 penetrating a plurality of connectors 4 is fixedly mounted on one end of the bus duct body 1 .

[0031] It should be noted that a mounting bolt 6 is disposed at one end of the bus duct body 1 , and the mounting bolt 6 passes through the connecting piece 4 to fix the entire structure and ensure the reliability and stability of the connection.

[0032] In an optional embodiment: the heat dissipation frame 31 is made of magnesium alloy material.

[0033] It should be noted that the heat dissipation frame 31 is made of a magnesium alloy material that is lightweight and has excellent thermal conductivity, and an aluminum alloy is even lighter, which can achieve extreme lightweight.

[0034] In an optional embodiment: the heat dissipation strip 32 is made of graphene reinforced material.

[0035] It should be noted that the heat dissipation strip 32 is made of graphene-reinforced material, and the graphene-reinforced material can significantly improve the thermal conductivity of the material by adding graphene nanosheets to the polymer.

[0036] In an optional embodiment, the corrugated fins 33 are ceramic-coated metal fins.

[0037] It should be noted that the corrugated fins 33 are made of ceramic-coated metal material. By coating a layer of ceramic material on the surface of the metal fin, the high temperature resistance and oxidation resistance of the metal can be improved while maintaining the high thermal conductivity of the metal.

[0038] Working principle: In the actual assembly process, first install the heat dissipation frame 31 inside the bus duct body 1, then install the heat dissipation bar 32, corrugated fins 33 and pin-shaped fins 34 to ensure that the components are tightly combined to form an efficient heat dissipation device. Then connect the adjacent heat dissipation devices through the connector 4, install the support bar 5 and finally use the mounting bolt 6 to tighten the whole. Effective heat dissipation inside the bus duct is achieved, the firmness and stability of the structure are ensured, and the needs of high-power and high-load electrical transmission are met.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
