▎ 摘　　要

NOVELTY - The device has a heat preservation cover movably connected with a top end of a box body. The box body is equipped with a heat radiation component that is provided with a photo-thermal absorbing plate (15), a heat transfer rib plate (12), a heat storage medium layer (13) and a graphene infrared radiation plate (11). The photo-thermal absorption plate is connected with the heat preservation cover and the graphene infrared radiation plate. The graphene infrared radiation plate is connected with a power source. The graphene infrared radiation plate radiates heat energy to a greenhouse, where the photo-thermal absorbing plate is an aluminum plate, the heat transmission rib plate is a Z-shaped plate, the heat storage medium layer is selected from paraffin or stearic acid and a heat insulating filling layer is made of rubber heat insulating material. USE - Graphene radiation enhancement device for greenhouse used in auxiliary facility field of agricultural planting. Can also be used in vegetable, flower, forest and other plant cultivation or seedling. ADVANTAGE - The graphene infrared radiation plate can radiate heat energy to the environment after switching on the power source. The photo-thermal absorption plate absorbs solar energy into heat energy during the day and stores solar energy in the heat storage medium layer through the heat transfer rib plate when the environment temperature is low, so that the heat radiation temperature can be maintained in the cold environment, thus setting graphene coating between the rigid substrate and the rigid clamping plate. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of a graphene radiation enhancement device.
