[0022] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Here, the schematic embodiments and descriptions of the present utility model are used to explain the present utility model, but do not limit the present utility model.

[0023] As Figures 1-3 shown, a corrugated cable tray facilitating heat dissipation includes a tray body 1 and a cover plate 2 installed on the top of the tray body 1.

[0024] The tray body 1 includes a bottom surface 11 and side surfaces 12 oppositely arranged on both sides thereof. The bottom surface 11 and the side surfaces 12 are corrugated. The length direction of the upward protruding part 16 of the bottom surface does not coincide with the length direction of the tray body 1, and the length direction of the inward protruding part 17 of the side surface coincides with the length direction of the tray body 1. The inward protruding part of the side surface 12 is provided with heat dissipation ventilation holes 13, and splicing structures are provided at both ends of the tray body.

[0025] The length direction of the upward protruding part 16 of the bottom surface is perpendicular to the length direction of the tray body.

[0026] The heat dissipation ventilation holes 13 on the two side surfaces 12 are oppositely arranged.

[0027] By designing the concave-convex corrugated structure, the heat dissipation performance of the cable tray is improved, the energy consumption and operation cost of the cable line system are reduced, and the overheating of the cable is avoided, reducing the risk of safety accidents such as fires, and improving the safety and stability of the cable line system. By designing the concave-convex corrugated structure, its strength and bearing capacity are improved, and the self-weight of the cable tray is reduced, thereby saving material costs and having significant energy-saving and environmental protection effects. The reduction of the self-weight also reduces the lifting difficulty during the installation process, thereby accelerating the project progress.

[0028] The heat dissipation ventilation holes 13 are arranged in groups of several, and several groups are arranged along the length direction of the side surface 12. By designing the concave-convex corrugated structure and providing the heat dissipation ventilation holes 13 on the side surface 12 to form a convection structure for the exchange of cold and hot air on both sides, the heat dissipation effect is further enhanced, and the cable tray can dissipate the heat generated by the cable to the maximum extent.

[0029] The top of the side surface 12 is provided with side surface screw holes 14 for installing the cover plate 2.

[0030] Furthermore, the cover plate 2 is provided with cover plate screw holes 21 matching the side surface screw holes 14, and the side surface screw holes 14 and the cover plate screw holes 21 are installed together through cover plate screws.

[0031] The splicing structure is splicing screw holes 15 and splicing screws. The splicing screw holes 15 are located at both ends of the non-inward protruding part of the side surface 12.

[0033] The materials of the cable tray body 1 and the cover plate 2 are selected from steel with a VCI bimetallic coating on the surface and color steel.

[0034] The surfaces of the cable tray body 1 and the cover plate 2 are treated by any one of the methods of fire prevention, plastic spraying, and galvanizing.

[0035] The galvanizing is hot-dip galvanizing.

[0036] During installation, match the splicing screw holes 15 at the front end of the rear cable tray body 1 with the splicing screw holes 15 at the rear end of the previous cable tray body 1, then connect the matched splicing screw holes 15 with splicing screws. After splicing the cable tray body to the specified length, lay the cable, and then place the cover plate 2 on the cable tray body 1. Match the cover plate screw holes 21 with the side screw holes 14, and then connect the matched cover plate screw holes 21 and side screw holes 14 with cover plate screws to complete the installation.

[0037] The advantages of the present utility model include: The cable tray adopts a concave-convex corrugated structure, and convection holes are provided on the side plates, so that the air inside the cable tray forms convection, enabling the heat inside the tray to be fully dissipated to the outside, avoiding overheating of the cable.

[0038] The design of the corrugated structure reduces the weight of the cable tray itself, reduces the difficulty of lifting and installation during the installation process, thus speeding up the project progress, and also improves its strength, bringing higher bearing capacity; The steel consumption of the cable tray of the present utility model saves more than 30% - 50% compared with the traditional ordinary cable tray.
