NOVELTY - The method involves setting two eudipleural gas tanks (1) in a sealed chamber. A vertical transparent pipe (5) is horizontally placed with a floating plate (6) capable of sliding up and down and matched with the movable sealing. The compressed gas is injected into the two gas tanks. The floating plate is made to move a certain distance to ensure that the height of the two floating plates is same. The hot oil is injected into two liquid storage barrels (2) through a mountain-shaped connecting pipe (8). The side pipe section at the bottom end of the liquid storage barrel is closed by a control valve (9), when the liquid surface in the middle pipe section is stable. The ascending situation of the floating plates in the two vertical transparent pipe at the left and right sides are observed. USE - Method for measuring heat dissipation performance of heat dissipation film on heating power device based on graphene. ADVANTAGE - The method has high measuring precision, the measuring result is intuitive and easy to understand, and dynamically embodies heat dissipation. The method is convenient to measure and study the thickness of the heat dissipation film and corresponding heat dissipation performance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram illustrating the method for measuring heat dissipation performance of heat dissipation film. 1Gas tank 2Liquid storage barrel 3Radiating fin 4Aeration pipe 5Vertical transparent pipe 6Floating plate 8Connecting pipe 9Control valve 11Distance sensor 12Aeration branch pipe
