▎ 摘　　要

NOVELTY - The tuner has a receiving end composite structure and a transmitting end composite structure that are arranged symmetrically with respect to the spacer (4). The receiving end composite structure is composed of a receiving end DC voltage generator (1), a receiving end substrate (2) and a receiving end graphene coating (3). The receiving end graphene coating is plated on the lower surface of the receiving end substrate. The receiving end DC voltage generator is connected to the receiving end graphene coating through a wire and a grid. The transmitting terminal composite structure is composed of a emitting terminal DC voltage generator (7), a emitting terminal substrate (6) and a transmitting terminal graphene coating (5). The emitting end graphene coating is plated on the upper surface of the emitting end substrate. The emitting end DC voltage generator is connected with the transmitting end graphene coating through a wire and a grid. USE - Near-field radiant heat tuner based on DC voltage biased graphene. ADVANTAGE - The tuner have a strong adjustment effect on the near-field radiation heat exchange capacity. The adjustment based on direct current does not interfere with other electronic components. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the near-field radiant heat tuner based on DC voltage biased graphene.
