Description

Technical Field

[0001] The utility model relates to the technical field of bus duct application, in particular to an I-type high-heat dissipation performance intensive bus duct. Background Art

[0002] In order to meet the needs of high-current low-voltage transmission lines in industrial and civil engineering construction, power distribution design adopts bus duct trunk system. In recent years, with the continuous increase in the capacity of transmission and distribution lines, bus duct trunk system has been widely used in engineering, and the structural design of bus duct products has also been gradually updated from air insulation type to dense insulation type, from steel plate shell to aluminum alloy shell. Bus duct is a closed metal device composed of copper and aluminum busbar columns. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk engineering projects.

[0003] When manufacturing and processing the existing intensive bus duct, generally multiple parts are assembled on the outer aluminum alloy shell, so that the whole structure needs a large number of bolts to connect and fix during use, which makes the operation difficult and unstable. At the same time, the intensive bus duct will generate a lot of high temperature during long-term use. The traditional heat dissipation method only conducts heat through the extruded plates on both sides, which cannot dissipate the internal high temperature in a timely and effective manner, resulting in reduced heat dissipation performance, thereby reducing the service life of the entire bus duct. Therefore, the utility model proposes an I-type high heat dissipation performance intensive bus duct. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an I-type high-heat dissipation performance intensive bus duct, by detachably arranging a plurality of heat-conducting dissipating mechanisms inside the intensive bus duct, so that the heat generated by the copper bar inside the bus duct can be quickly conducted and dissipated, so that the copper bar can be quickly cooled during use, and the overall service life is improved. At the same time, a graphite sheet is arranged between two adjacent copper bars, and the heat-conducting dissipating mechanisms are further cooperated to quickly absorb and conduct the heat generated by the copper bar, thereby achieving a high-performance heat dissipation effect.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an I-type high-heat dissipation performance intensive bus duct, including an I-type bus duct body, a plurality of installation grooves are evenly opened on both sides of the I-type bus duct body, and the interiors of the plurality of installation grooves are all snap-connected with heat dissipation mechanisms, and the two side walls of the I-type bus duct body are symmetrically and tightly provided with copper bars, and graphite heat sinks are tightly provided between two groups of the copper bars.

[0006] The utility model is further configured as follows: the heat dissipation mechanism includes two heat-conducting frames engaged in the mounting groove, both side walls of the two heat-conducting frames are fixedly connected with heat-conducting sheets, U-shaped grooves are provided on the side walls of the two heat-conducting frames that are far away from each other and close to the end faces, two sliding rods are slidably connected through the opposite end faces of the two heat-conducting frames and located at the U-shaped grooves, springs are sleeved on the outer walls of the two sliding rods near the end faces, the end faces of the two groups of springs are respectively tightly fitted with the inner walls of the two U-shaped grooves, and the end faces of the two heat-conducting frames that are far away from each other are fixedly connected with heat dissipation blocks.

[0007] Through the above technical solution, two heat-conducting frames are used to slide on the slide rod to squeeze the springs on both sides, so that the entire heat-conducting frame can be placed in the installation groove, and then the heat-conducting frame is loosened, and the elasticity of the internal spring is used to make the two heat-conducting frames slide relative to each other through the U-shaped groove, so that the heat dissipation block on the end surface is engaged in the first slot, and then the installation is completed, and the copper bars on both sides can quickly transfer the generated heat to the heat-conducting frame through the heat-conducting sheet, and then quickly dissipate it through multiple heat dissipation blocks, thereby improving the heat dissipation efficiency of the heat generated inside the copper bar.

[0008] The utility model is further configured as follows: the two heat-conducting frames have the same structure and are slidably arranged to cover each other through the U-shaped groove.

[0009] The above technical solution facilitates mutual sliding of the heat-conducting frames during installation, thereby facilitating adjustment of the heat-conducting dissipation mechanism to be installed, and further allowing the heat-conducting dissipation mechanism to be quickly and accurately installed inside the installation slot.

[0010] The utility model is further configured as follows: first card slots are provided at the tops and bottoms of the plurality of mounting slots, and the plurality of groups of first card slots penetrate the I-type bus trough body; the plurality of groups of heat dissipation blocks are respectively connected to the plurality of corresponding first card slots in a card-engaging manner, and penetrate the top and bottom of the I-type bus trough body through the plurality of groups of first card slots.

[0011] The above technical solution facilitates the positioning and engagement of the entire heat dissipation mechanism during installation, and the first card slot and the heat dissipation block are used for positioning, thereby facilitating rapid installation and subsequent disassembly of the heat dissipation mechanism.

[0012] The utility model is further configured as follows: two copper bars close to the I-type bus trough body are arranged in close contact with the side walls of the plurality of heat dissipation mechanisms.

[0013] Through the above technical solution, the heat generated by the copper busbar installed inside the entire bus duct can be quickly absorbed and transferred, preventing the heat generated by the internal copper busbar from being difficult to quickly remove, thereby improving the service life of the entire bus duct.

[0014] The utility model is further configured as follows: the tops and bottoms of the two graphite heat sinks are fixedly connected with a plurality of heat dissipation extension blocks, the tops and bottoms of the I-type busbar trough body and near the middle are provided with a plurality of second card slots, and are respectively connected with the plurality of heat dissipation extension blocks through the plurality of second card slots.

[0015] Through the above technical solution, the heat generated between the two copper bars can be quickly absorbed and transferred by utilizing the thermal conductivity of the graphite material itself, thereby quickly conducting the absorbed heat out, thereby improving the heat dissipation efficiency between the two copper bars.

[0016] The utility model is further configured as follows: the top and bottom of the I-type bus trough body and near the end surface are bolted with positioning mounting blocks, and the two groups of positioning mounting blocks at the top and bottom are bolted to the two extruded side panels, and the side walls away from the two extruded side panels are fixedly connected with a plurality of heat dissipation fins, and the cross-sections of the two groups of heat dissipation fins are arranged in an isosceles trapezoidal shape, and the end surfaces of the I-type bus trough body are respectively bolted with side connecting frames through positioning mounting block bolts.

[0017] Through the above technical scheme, the two sets of positioning and mounting blocks on the I-type bus trough body can be used to quickly bolt and fix the side connecting frame of the end face, and it is convenient to disassemble and replace it later. The multiple heat dissipating fins on the extruded side panel can absorb and dissipate the heat emitted by the internally bonded copper busbar, and the cross-section of the heat dissipating fin is arranged in an isosceles trapezoidal shape, which can gradually increase the space between adjacent heat dissipating fins, thereby facilitating the rapid dissipation of heat and improving the heat dissipation efficiency.
