[0002] Busbars are conductive metal materials widely used in power distribution systems. They are mainly used to conduct electricity from the power source to various loads. They are mainly made of copper and aluminum and have the characteristics of high conductivity and corrosion resistance. Common forms include flat bars, rectangular bars, and tubular bars. Their oxidation resistance can be enhanced by tin plating. As a key connection point of electrical equipment, the heat dissipation characteristics and standardized design of busbars ensure the safety and stability of power transmission.

[0010] Preferably, the heat sink has a plurality of ventilation holes evenly distributed on it.

[0011] By adopting the above technical solution, the ventilation holes increase the heat dissipation area of ​​the heat sink, improve air circulation, and further enhance the heat dissipation effect.

[0012] Preferably, the edge portion of the heat sink is provided with a protective plate, and a protective mesh is provided on the protective plate.

[0013] By adopting the above technical solutions, the guard plate and protective net can prevent foreign objects from entering the cooling device, thereby improving safety and reliability.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] An active heat dissipation structure for a marine high-current busbar includes a composite busbar 1, a circulating pump 2, and a cooling device 3.

A circulation pipeline 6 connects the shunt pipes 4, the circulating pump 2, and the cooling device 3 to interconnect them. The composite busbar 1 includes a busbar body 11, with insulating and thermally conductive layers 12 on both the upper and lower sides of the busbar body 11. The insulating and thermally conductive layers 12 are made of engineering plastic through epoxy resin vacuum injection, providing high thermal conductivity and high insulation. Heat dissipation layers 13 are respectively provided on the two sets of insulating and thermally conductive layers 12, and multiple sets of heat dissipation channels 14 are connected to the heat dissipation layers 13. The multiple sets of heat dissipation channels 14 are respectively connected to the multiple sets of guide pipes 5, allowing coolant to flow through the heat dissipation channels 14, thereby improving the heat dissipation efficiency of the busbar body 11 and enhancing the busbar's performance.

[0023] Furthermore, the cooling device 3 includes a heat sink 31, which is hollow and contains an appropriate amount of coolant. Both ends of the heat sink 31 are connected to the circulation pipe 6. A drive motor 33 is fixedly connected to the heat sink 31, and a fan blade 34 is fixedly connected to the output shaft of the drive motor 33. The drive motor 33 controls the fan blade 34 to rotate stably, thereby cooling the heat sink 31 and removing the heat carried in the coolant.

[0024] Furthermore, multiple ventilation holes 36 are evenly provided on the heat sink 31, which can increase the heat dissipation area of ​​the coolant and improve the heat dissipation effect.

[0025] Furthermore, a protective plate 37 is provided at the edge of the heat sink 31, and a protective mesh 35 is provided on the protective plate 37, which can protect the cooling device 3 and improve its safety.

[0026] Furthermore, four sets of support legs 32 are provided at the bottom of the heat sink 31 to support the cooling device 3.

[0027] The implementation principle of this embodiment is as follows: when the busbar body 11 generates heat through a large current, the heat is conducted to the heat dissipation layer 13 through the insulating heat-conducting layer 12. The coolant flows from the circulation pump 2 through the circulation pipe 6 into the branch pipe 4, and enters the heat dissipation channel 14 through the guide pipe 5. After absorbing heat, it returns to the cooling device 3. In the cooling device 3, the coolant in the heat dissipation plate 31 is cooled by the airflow generated by the fan blade 34, and then circulates again to achieve active heat dissipation.
