NOVELTY - The utility model claims a graphene preparation device, comprising a tank body, a first pipeline and a second pipeline; the three are isolated from each other; the first pipeline is used for containing graphene mixed liquid; the second pipeline and the tank body are used for containing the cooling medium; and the cooling medium covering the first pipeline is liquid cooling medium. taking away the heat generated by graphene high temperature oxidation through the liquid radiating medium; compared with the existing technology by means of gaseous radiating medium radiating, the efficiency of the liquid radiating medium is higher; the same quality medium can take away more heat, which not only can reduce the volume of the whole radiating system, but also can improve the radiating effect.
