Abstract
Description
Technical Field
[0001] This utility model relates to the field of stirring technology, and in particular to a stirring device for the production of graphene thermal conductive sheets. Background Technology
[0002] Graphene thermal pads are a novel type of heat-conducting and heat-dissipating material that conducts heat evenly in both directions, shielding heat sources and components while improving the performance of consumer electronics.
