▎ 摘　　要

NOVELTY - The compound heat-conducting structure has a heat conducting base whose two sides are provided with multiple mounting seats. The mounting seat is provided with a mounting hole. The top end of the mounting seat is fixedly provided with an evaporation type heat conducting cavity that is connected with a liquid storage type heat-conduction cavity (8). The bottom end of a composite heat conduction heat conducting plate is formed with multiple low boiling point medium reflux grooves and multiple second low-boiling point medium reflux groove. The inner side wall of the low-Boiling point reflux groove and a heat convection chamber (13) are fixedly formed with a graphene- like heat conducting inner film layer (15). USE - Composite heat-conducting structure based on ultra-wide artificial graphite high-conductivity film for use in electronic device such as mobile phone. ADVANTAGE - The composite heat-conducting structure can collect heat conduction and heat convection to form a combined heat conducting structure, using ultra-wide artificial graphite high-thermal conductivity film to improve the heat conducting effect, at the same time, using the heat pipe principle to effectively improve the conduction efficiency, so as to realize the fast transmission of heat, realizing high performance heat dissipation.
