Description

Technical Field

[0001] The present invention is a high heat dissipation busbar trunking based on modular design. Background Art

[0002] A busbar trunking is an enclosed metal device composed of copper or aluminum busbars, used to distribute relatively high power to each component of a decentralized system. It has increasingly replaced wire and cable in indoor low-voltage power transmission trunk line engineering projects.

[0003] The heat dissipation problem of the busbar trunking is mainly reflected in its poor heat dissipation performance, which is mainly caused by its structural characteristics. The poor heat dissipation of the air-type busbar trunking is mainly because of its large volume, and since both ends are closed and there are insulating brackets separating each section, the air cannot circulate inside the busbar trunking, thus affecting the heat dissipation effects of convection and conduction. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and provide a high heat dissipation busbar trunking based on modular design.

[0005] A high heat dissipation busbar trunking based on modular design includes a busbar trunking body, and the busbar trunking body is installed in a housing. The housing includes an upper cover plate, a lower bottom plate, a left side plate, a right side plate, a front side plate, and a rear side plate. An installation groove is provided on the upper end surface of the upper cover plate, and an air cooling mechanism is provided in the installation groove. A through hole is provided at the bottom of the installation groove, and the through hole is communicated with an installation cavity. The installation cavity is located inside the upper cover plate and penetrates the left end surface and the right end surface of the upper cover plate. An installation rack is installed in the installation cavity. A plurality of first ventilation holes are arranged at intervals and in parallel on the upper end surface of the installation rack.

[0007] Further, the refrigeration material is a phase change material.

[0008] Further, the left side plate and the right side plate have the same structure and are mirror-symmetrically arranged on both sides of the upper cover plate. The right side plate is a C-shaped groove plate-like structure, which includes an upper plate, a middle plate, and a lower plate. The upper end and the lower end of the middle plate are respectively connected to one end of the upper plate and the lower plate. A plurality of installation holes are arranged in parallel at intervals on the surface of the middle plate, and heat dissipation fins are inserted into the installation holes.

[0009] Further, the heat dissipation fins are fixed in the installation holes by welding.

[0010] Furthermore, the upper plate sections of the left and right plates are provided with downwardly concave curved slide grooves, and the two ends of the lower end surface of the upper cover plate are provided with raised positioning blocks, and the positioning blocks are slidably matched with the slide grooves.

[0011] Furthermore, the air cooling mechanism includes a limit bar and a supporting shell. An air-cooled radiator is arranged in the supporting shell. The limit bar is installed on the two side edges inside the mounting groove. The inner side wall surface of the limit bar is provided with a groove-shaped guide rail.

[0015] Beneficial effect: Compared with the prior art, the present invention installs an air-cooled radiator by cooperating with the guide rails on the limit bars in the installation groove and the guide blocks on both sides of the supporting shell, and sets the refrigeration material through the inner cavity in the installation frame. The cold air emitted by the refrigeration material below the air-cooled radiator is blown into the interior of the shell through the air-cooled radiator, and then discharged through the second ventilation holes on the lower bottom plate. In the process, not only the hot air originally inside the shell is discharged, but also the bus duct body is cooled by the cold air. At the same time, the heat dissipation fins of the left and right plates can also assist in heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS
