▎ 摘　　要

NOVELTY - The device has a LED light source unit adhered on a bottom part of a substrate. A single-layer graphene interface is fixed on the substrate. The LED light source unit is engaged with a contact interface that is formed with a composite layer, where the composite layer is coated with heat-conducting adhesive material. A screwing bolt is fixed on the substrate, where the heat-conducting adhesive material is selected from silicon glue, silicone or epoxy resin material. USE - Large power LED graphite alkenyl radiating device. ADVANTAGE - The device has high heat conductivity effect, better heat sink temperature uniformity and reasonable design, and increases heat exchange ability and radiating efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a large power led graphite alkenyl radiating device.
