▎ 摘　　要

NOVELTY - The closed cycle type graphene smart wearable device comprises a heat generating module (1) realizes heat generation by a graphene film on a wall of a partial silica gel pipe equipped inside. The inside of the heat generating module is provided with a hose passage (2) for transferring heat. The hose passage is connected to a peristaltic pump (3) for providing heat transfer power. USE - Closed cycle type graphene smart wearable device used for low voltage. ADVANTAGE - The closed cycle type graphene smart wearable device has good safety, improved heating effect, low energy consumption and green energy saving for low voltage. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of closed cycle type graphene smart wearable device. Heat generating module (1) Hose passage (2) Peristaltic pump (3) Control system (4) Temperature sensor (5)
