▎ 摘　　要

NOVELTY - The device has a soil coupler (2) that is arranged in an energy storage well (1), and the soil coupler is arranged along the depth direction of the energy storage well. The soil coupler has a fluid channel for fluid to circulate, which externally extend coupling unit (4) is fixedly arranged on the outer periphery of the soil coupler, and the coupling unit or/and the soil coupler have a graphene heat conducting layer. The coupling unit is provided with multiple coupling portions are distributed at intervals on the outer circumference of the soil coupler, and one heat exchange tube (5) is arranged between adjacent coupling unit. USE - Device for enhancing radiation energy storage by using graphene. ADVANTAGE - The method enables strengthening the radiation heat exchange power of the soil coupler by adding the graphene material to the soil coupler and outer peripheral coupling unit of the soil coupler, thereby enhances the radiation energy storage capacity of the soil coupler. The heat conducting coefficient of the graphene soil coupler reaches 0.79W/(m.k), and the radiation heat exchange power is greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for enhancing radiation energy storage by using graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a top view of the device for enhancing radiation energy storage by using graphene.
