Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] Embodiment 1

[0031] As Figure 1 shown;

[0032] A ventilated slot type cable bridge facilitating heat dissipation of cables, comprising a body 1 and a slot cover 12 arranged on the surface of the body 1.

[0033] In the present embodiment: the existing body 1 is reinforced by a reinforcing bottom plate and side ribs, which originally form an integral cable bridge. The reinforcing bottom plate and side ribs ensure the stability of the connection between the bridge slot body and the reinforcing bottom plate and side ribs, thereby improving the strength of the overall bridge, and the structure is simple and convenient for production. For specific working processes, refer to the technology disclosed in "CN219843367U discloses a slot type cable bridge". However, in the existing design, the heat generated by the above-mentioned cables during operation is difficult to dissipate. This existing technology adopts a closed structure, relies only on natural heat dissipation, lacks effective air flow channels, has poor material thermal conductivity, and heat is easily accumulated. The cables run in a high-temperature environment for a long time, accelerating the aging of the insulation layer, shortening the service life, and high temperature easily causes short circuit, fire and other safety accidents, reduces power transmission efficiency, and increases energy consumption. In combination, this problem is obviously a real problem and difficult to solve. Therefore, to solve this technical problem, adjustable heat dissipation mechanism 2 and auxiliary heat dissipation mechanism 3 are added in the present application.

[0034] Further,

[0038] In the embodiment, the body 1 serves as the main structure of the body 1 for accommodating the cable, and the slot cover 12 serves to protect the cable. Since there is a heat source such as the cable inside the body 1, the internal air temperature will rise, and the hot air will rise, thereby forming a certain negative pressure inside the body 1.

The air inlet amount and the air inlet direction can be automatically adjusted according to the temperature, humidity and other parameters in the body 1, the intelligent level of heat dissipation is improved, and the manual intervention is reduced.
