▎ 摘　　要

NOVELTY - The phase change heat storage module has several phase change sheets and several high thermal conductivity graphene films enclosed in a box frame. The box frame is a metal box. The hot pressed into a thin sheet, after uniformly mixing the phase change material and the thermal conductive material. The phase change material is phase change paraffin, phase change hydrated salts, polyethylene glycol or solid polyol. USE - Phase change heat storage module used in phase change regenerative electric heater (Claimed). ADVANTAGE - The thermal conductivity graphene film in the box is high. The thermal conductivity of the module is enhanced. The phase change material is fully absorbed or release heat. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of phase change heat storage module.
