DETAILED DESCRIPTION

[0021] 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.

[0022] A bus duct with a heat dissipation structure according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0023] Example

[0024] For easier understanding, see Figures 1 to 3 The utility model provides an embodiment of a bus duct with a heat dissipation structure, comprising a bus duct body 1, mounting plates 2 are fixedly installed on both sides of the top of the bus duct body 1, and heat absorbing plates 4 are installed in the mounting plates 2. Two bundles of PE busbars 3 passing through the heat absorbing plates 4 are arranged in the middle of the bus duct body 1, and heat conducting plates 5 are fixedly connected to both sides of the bottom of the heat absorbing plates 4, and a heat conducting mechanism is arranged on one side of the heat conducting plates 5;

[0025] The heat-conducting mechanism includes two heat-conducting parts 6, a plurality of heat-conducting tubes 7 and a heat collecting block 8. The two heat-conducting parts 6 are fixedly connected to the two ends of one side of the heat-conducting plate 5, the plurality of heat-conducting tubes 7 are respectively fixedly connected to the side walls of the two heat-conducting parts 6, and the heat collecting block 8 is fixedly connected between the heat-conducting tubes 7 on the two heat-conducting parts 6.

[0026] It should be noted that the bus duct body 1 is a hollow structure to accommodate the cable arrangement of electrical equipment. A heat absorbing plate 4 is embedded in the mounting plate 2, and the heat absorbing plate 4 runs through the top of the bus duct body 1 to absorb the heat generated during the operation of the PE busbar 3. The bottom of the heat absorbing plate 4 is connected to the heat conducting plate 5 through fasteners, and the heat conducting plate 5 has a heat conducting mechanism. A certain gap is maintained between the heat conducting plate 5 and the side of the bus duct body 1 to facilitate air circulation and improve the heat dissipation effect.

[0027] In the heat conduction mechanism, two heat conducting members 6 are fixed on both sides of the heat conducting plate 5, and the side walls of the heat conducting members 6 are connected to a plurality of heat conducting thin tubes 7 through fixing members, and the thin tubes 7 are arranged along the length direction of the heat conducting members to form an effective heat conduction path. The heat collecting block 8 is located between the two heat conducting members 6 and connected through the heat conducting thin tubes 7 to achieve heat concentration and dissipation, thereby ensuring that the bus duct has good heat dissipation performance.

[0028] Among them, an interlayer board located between two bundles of PE busbars 3 can also be arranged inside the bus duct body 1, and a hollow heat dissipation hole can be arranged at one end of the bus duct body 1. An interlayer board is arranged inside the bus duct body 1, and the interlayer board is located between the two bundles of PE busbars 3. The material of the interlayer board is also selected to have excellent insulation performance and high temperature resistance, such as FR-4 glass fiber board or polycarbonate board. Its function is to effectively isolate busbars of different phases to prevent electrical interference and short circuit risks. At the same time, it can also serve as a physical support to maintain the stable arrangement of the busbars and avoid damage caused by vibration. Considering the heat generated during the operation of electrical equipment, hollow heat dissipation holes are cleverly arranged at one end of the bus duct body 1. These heat dissipation holes are reasonably distributed, and can be either regular geometric arrangements, such as circular and rectangular arrays, or irregular opening patterns. The design is optimized based on thermal flow analysis to maximize air circulation. The size and number of heat dissipation holes are determined by calculation to ensure that heat can be effectively dissipated without affecting the insulation performance and dustproof and waterproof level of the internal busbar. Air circulates freely through these pores, taking away the heat in the busbars and bus ducts, thereby improving the system's thermal management efficiency and extending the life of the equipment.

[0029] In an optional embodiment: a screw hole is opened on the top of the mounting plate 2, and the mounting plate 2 is fixed on the bus duct body 1 through a fastener in the screw hole.

[0030] It should be noted that the mounting plate 2 is fixed to the bus duct body 1 by fasteners to ensure the firmness of the connection between the mounting plate 2 and the bus duct body 1 .

[0031] In an optional embodiment: two bundles of PE busbars 3 are located on both sides of the bus duct body 1, and a partition is provided in the middle.

[0032] It should be noted that two bundles of PE busbars 3 are arranged on both sides of the bus duct body 1, with a partition in the middle to prevent electromagnetic interference and short circuit risks, while also helping to maintain air circulation and optimize the heat dissipation channel.

[0033] In an optional embodiment: one end of the heat conducting member 6 is in a truncated cone shape, and the bottom of the truncated cone is fixedly connected to one end of the heat conducting plate 5 .

[0034] It should be noted that one end of the heat conducting member 6 is designed to be truncated into a cone shape, which is tightly combined with the heat conducting plate 5 to enhance thermal conductivity and structural stability.

[0035] In an optional embodiment: a heat insulating sleeve 9 is fixedly connected to the side wall of the heat conducting member 6 , and the heat insulating sleeve 9 is sleeved on the outside of the heat conducting capillary tube 7 and the heat collecting block 8 .

[0036] It should be noted that in order to avoid reverse heat transfer, an insulating sleeve 9 is installed on the side wall of the heat conductor 6. The insulating sleeve 9 not only wraps the heat-conducting tube 7, but also extends to cover the outside of the heat collecting block 8 to form an insulating layer to ensure directional heat transfer.

[0037] In an optional embodiment: the heat insulation sleeve 9 is made of rock wool material, and the heat collecting block 8 is made of copper material.

[0038] It should be noted that the insulation sleeve 9 is made of lightweight and efficient rock wool material with good thermal insulation performance, thereby reducing the impact of the heat collecting block 8 on the PE busbar 3; the heat collecting block 8 is made of copper material because copper has excellent thermal conductivity and can quickly conduct the absorbed heat to the external environment.

[0039] In an optional embodiment: a heat dissipation port 10 is provided on one side of the heat insulation sleeve 9 , and the heat dissipation port 10 is located on one side of the heat collecting block 8 .

[0040] It should be noted that a heat dissipation port 10 is provided on one side of the heat insulation sleeve 9 , and the heat dissipation port is aligned with the heat collecting block 8 , which promotes the effective release of heat and enhances the heat dissipation efficiency.

[0041] The fasteners in the present invention can be bolted or welded, and the heat absorbing plate 4 is made of aluminum alloy, and the heat conducting plate 5, the heat conducting member 6 and the heat conducting tube 7 are all made of copper.

[0042] Working principle: The PE busbar 3 generates heat when current passes through it, and the heat is first absorbed by the heat absorbing plate 4 which is close to the top of the busbar main body 1. As the first line of defense, the heat absorbing plate 4 quickly absorbs and conducts heat to prevent heat accumulation around the busbar. The heat conducting plate 5 connected to the bottom of the heat absorbing plate 4 further transfers the heat to the heat conducting mechanism. The heat conducting mechanism includes a heat conducting member 6, a heat conducting capillary 7 and a heat collecting block 8, forming an efficient heat conduction path. The heat conducting member 6 acts as a bridge to transfer heat from the heat conducting plate 5 to the heat conducting capillary 7. The heat conducting capillary 7 acts as an efficient channel for heat conduction, dispersing the heat and quickly transferring it to the heat collecting block 8. The heat collecting block 8 acts as a concentration point of heat energy, and due to the excellent thermal conductivity of the copper material, it can quickly diffuse the heat. The heat dissipation port 10 is located on one side of the insulation sleeve 9, with the purpose of providing a discharge port for hot air flow. When the heat collected by the heat collecting block 8 is transferred and accumulated through the heat conducting tube 7, the hot air flows through the heat dissipation port 10 for natural convection or forced exhaust by the fan, accelerating the heat dissipation to the external environment, thereby achieving effective heat dissipation. The symmetrical arrangement of the two PE busbars 3 and the partition design in the middle help to isolate the electricity and reduce electromagnetic interference, while providing a path for the hot air to circulate, avoiding local overheating and enhancing the overall heat dissipation effect.

[0043] 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
