NOVELTY - The utility model claims a graphene material interface thermal resistance measuring device. the measuring device comprises an upper cylinder, a lower cylinder, an upper top cover, a press, water circulation cooling unit, a displacement detecting unit, a heating unit, a temperature detecting unit and a data processing unit, the upper and lower cylinders are respectively provided with a first metal block and a second metal block, the test sample is set between two metal blocks, the upper top cover is located above the first metal block, press connected with the upper top cover. The utility model uses the pressure machine exerts pressure to the upper top cover, an upper top cover transmits the pressure to the test sample, the test sample is compressed using a displacement detecting unit for real-time monitoring and collecting the test sample displacement value under different stress, obtaining the compression rate of the test sample, and the test sample measurement of interface thermal resistance at different compression ratios. The device of the utility model has simple structure, high measuring precision, good reliability and measuring range.
