NOVELTY - This utility model relates to electrical over-heat field, especially relates to a high heat-transfer graphene-elements. comprising a base, which is equipped with a thermal control assembly, said heat control component comprises a thermal control base which can move up and down sliding connection and heat control cover, thermal base middle part is provided with a cavity, the heat control cover is equipped with a volatilizing cavity, liquid and volatile cavity communicated up and down, heat control cover side end is graphene conductive section, the lower end is the insulating section, the base is located in the thermal control base is further provided with a graphene heat conducting module. The utility model overcomes the over-heat prevention structure in the existing technology cannot cut off the heating source from the source over the defect of bad effect of heat, so it can automatically cut off the electric circuit when the electric machine overheating, completely cutting heat source, sensitive reaction, high precision, improving the electrical safety to use.
