▎ 摘 要
NOVELTY - An optical fibre module switching device, comprising a switching box, the switching box end face is provided with a crystal head assembling groove, and the switching box side wall is provided with a radiating hole, the radiating groove on the lower surface of the switching box is compounded with a graphene patch, the bottom of the graphene patch is fixedly connected with a copper-aluminium alloy heat-conducting plate, the lower surface of the copper-aluminium alloy heat-conducting plate is fixedly connected with the copper-aluminium alloy radiating plate, the corner position of the lower surface of the switching box is fixedly connected with the ceramic supporting leg, the upper surface of the switching box is detachably cover plate, the middle position of the lower surface is cover plate connected with the desiccant storage box, on the basis of the original radiating hole of the switching box, the lower surface of the switching box is provided with a graphene patch, a copper-aluminium alloy heat-conducting plate and a copper-aluminium alloy radiating plate, the graphene patch performs heat-conducting treatment to the switching box, the copper-aluminium alloy heat-conducting plate and the copper-aluminium alloy radiating plate accelerate the heat dissipation of the switching box, reducing the accumulation of the heat in the switching box, improving the radiating performance and using effect.
