▎ 摘　　要

NOVELTY - The device has thermocouple (5) and sheet heating film which are fixedly arranged between heat insulation plate (1) and phase change material cube module (4). The heat insulation plate and phase change material cube module are formed on sheet heating film. The phase change material cube module is tightly connected with sheet heating film to form a heat conducting bridge. The phase change material cube module is kept in contact with any foreign object. The temperature of phase change material cube module is detected by thermocouple. USE - Device for detecting heat radiation performance of phase change material of graphene-paraffin composite material. ADVANTAGE - The heat dissipation effect of different ratios of graphene/paraffin composite materials is measured conveniently and accurately. The heat dissipation performance of different ratios of graphene/paraffin composites is compared and analyzed easily. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for detecting heat radiation performance of phase change material of graphene-paraffin composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for detecting heat radiation performance of phase change material.
