It undertakes the task of power distribution in the power supply system and is used for connecting low-voltage distribution panels with large and medium-sized loads. It is widely used in modern workshops, factories and high-rise buildings.

[0003] The busbar will generate a lot of heat during use. If the heat cannot be dissipated to the outside of the bus duct in time, the ambient temperature of the busbar will be high. Long-term exposure to high temperature will seriously affect the service life of the busbar. The existing air-type bus duct has a small heat dissipation area, and the heat can only be dissipated to the outside of the bus duct from the gap between the busbars, resulting in low heat dissipation efficiency.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 , the present invention provides a technical solution:

[0031] An improved air heat dissipation bus duct comprises two sets of side fixing plates 61, between which the top cover 2 and the bottom cover 8 are fixedly connected, respectively, and the two fixing plates 6 cooperate with the top cover 2 and the bottom cover 8 to form a rectangular structure;

[0032] The top cover 2 and the bottom cover 8 are designed as hollow structures, and a partition 9 is movably connected between the top cover 2 and the bottom cover 8 at an equal distance, and a mounting groove 4 is formed between adjacent partitions 9, and a busbar body 5 is installed in the mounting groove 4;

[0033] The lower end surface of the bottom cover 8 is provided with a modular heat dissipation mechanism;

[0034] The modular heat dissipation structure includes a bottom cover 8 whose lower end surface is movably connected to a fixed plate 6, and an axial flow fan 7 is embedded in the fixed plate 6, and a plurality of extrusion springs 10 are evenly fixedly connected to the front and rear sides of the partition 9, and the partition 9 is made of insulating material, and a transmission connection is arranged between the top of the partition 9 and the top cover 2.

[0035] The present application designs a movable partition 9 in conjunction with a rectangular bus duct structure, which allows the user to adjust the spacing of the installation slots 4 according to busbars of different thicknesses to meet the requirements of busbar placement and installation. At the same time, the busbar is flexibly clamped and fixed by squeezing the spring sheet 10 to maintain stability of the busbar.

[0036] Specifically, the transmission structure includes a movable groove 11 opened on the lower end surface of the top cover 2, and a slider 14 is slidably connected in the movable groove 11, the slider 14 and the movable groove 11 are of T-shaped structure design and cannot be separated, the lower end surface of the slider 14 is fixedly connected to the partition 9, the slider 14 is internally rotatably connected with an internal threaded sleeve 16, and an electromagnetic ring is sleeved between the slider 14 and the internal threaded sleeve 16, the electromagnetic ring is fixedly connected to the slider 14, the movable groove 11 is internally rotatably connected with a threaded rod 13, and one end of the threaded rod 13 is sleeved and fixed with a bearing 15, the bearing 15 is located inside one end of the movable groove 11, and the other end of the threaded rod 13 passes through the movable groove 11 and extends to the outside of the side fixed plate 61 and is fixed with a knob 3.

[0037] By adopting the above technical solution, when working, the space size of the installation groove 4 required for the busbars of different thicknesses is different. At this time, the user can control the slider 14 on the specified partition 9 through a controller externally connected to the electromagnetic ring, and the electromagnetic ring inside the slider 14 is magnetically attracted and fixed to the internal threaded sleeve 16. Then the user drives the threaded rod 13 to rotate by rotating the knob 3, and then drives the slider 14 to move and adjust the position of the partition 9 inside the movable groove 11, and then adjust the distance between adjacent partitions 9, thereby improving the adaptability and use effect of the device.

[0038] Specifically, a magnet 17 is embedded inside the bottom cover 8, and plug-in slots are provided at equal distances on the lower end surface of the bottom cover 8. A plug-in block 12 is plugged into the plug-in slot, and the upper end surface of the fixed plate 6 is fixedly connected to the plug-in block 12, and the fixed plate 6 is made of magnetic metal material.

[0039] By adopting the above technical solution, the plug-in block 12 is plugged into the plug-in slot, and then the fixing plate 6 is fixed by means of the magnet 17 magnetically attracting the bottom cover 8, thereby realizing the modular heat dissipation mechanism to be selectively installed according to the heating node of the bus duct, and the heating temperature can be measured by the user through a thermometer.

[0040] Specifically, the extrusion spring sheet 10 is wrapped with an insulating rubber sheet, and the partition plate 9 is made of a heat-conducting metal material.

[0041] By adopting the above technical solution, the material of the partition 9 can be selected according to the specific use requirements. For example, the bus duct used for high-current and high-power equipment must use a partition 9 made of insulating material to prevent high current breakdown. For low-power equipment, insulation can be achieved by wrapping a rubber sheet around the extruded spring sheet 10. The partition 9 is made of heat-conducting metal to improve heat conduction in the installation slot 4 and improve the effect of air heat dissipation on cooling the bus duct.

[0042] Working principle: During operation, the installation slot 4 required for busbars of different thicknesses is different in size. At this time, the user can control the slider 14 on the designated partition 9 through an external controller connected to the electromagnetic ring, and the electromagnetic ring inside the slider 14 is magnetically attracted and fixed to the internal threaded sleeve 16. Then the user drives the threaded rod 13 to rotate by rotating the knob 3, and then drives the slider 14 to move and adjust the position of the partition 9 inside the movable slot 11, and then adjust the spacing between adjacent partitions 9, thereby improving the adaptability and use effect of the device. The plug-in block 12 is plugged into the plug-in slot, and then the fixed plate 6 is connected to the plug-in slot through the magnet 17 The bottom cover 8 is fixed by means of a magnetic suction, so that the modular heat dissipation mechanism can be selectively installed according to the heating node of the bus duct. The heating temperature can be measured by the user through a thermometer. The material of the partition 9 can be selected according to the specific use requirements. For example, the bus duct used for high-current and high-power equipment must use a partition 9 made of insulating material to prevent high current breakdown. For low-power equipment, the insulation can be achieved by wrapping a rubber sheet around the outside of the extruded spring sheet 10. The partition 9 is made of heat-conducting metal to improve heat conduction in the installation slot 4 and improve the effect of air heat dissipation on cooling the bus duct.
