▎ 摘　　要

NOVELTY - The device has a rectangular block whose upper end is fixed with an expansion board (10). A bottom plate (11) is arranged above the expansion board. The expansion board is hinged and fixed to the bottom plate. A gear (8) is coaxially fixed with a threaded rod (12). The upper end of the threaded rod is threadedly connected with a vertical sliding sleeve (13). The upper end of the casing is hinged with a connecting rod (14). The upper end of the connecting rod is hingedly fixed to the bottom plate. A fan (4) is fixed above a bottom plate (11). The upper end of a support plate is provided with a cam groove. A pulley is slidably provided in the cam groove. The upper end of the pulley runs through the cam groove and is fixedly connected with a rectangular block. The track shape of the cam groove is an irregular shape other than a circle. USE - Cooling device for production of graphene used in biological medicine and drug delivery. ADVANTAGE - The graphene device comprises a supporting frame and a furnace body that is fixedly connected with the supporting frame, where outer circumference of the furnace body is wound with a condensing pipe that is spirally arranged, and thus enables to improve the cooling efficiency of the graphene device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the cooling device for production of graphene. 4Fan 8Gear 9Rack 10Expansion board 11Bottom plate 12Threaded rod 13Sliding sleeve 14Connecting rod
