Graphene heating plate with packaging structure

Abstract

The invention discloses a graphene heating plate with a packaging structure, and the graphene heating plate is characterized by comprising a graphene heating film, an insulating layer, a metal housing, and an end cover; the graphene heating film comprises a graphene film sheet and two electrodes fixedly arranged along the edge of the graphene film sheet, one end of each electrode forms an electrode leading-out end at the wide edge of the graphene film sheet, the insulating layers fixedly cover the upper surface and the lower surface of the graphene heating film to form a heating plate body, the metal shell is a thin-wall shell, the cross section of the heating plate body is of a flat annular structure, the heating plate body is sealed, packaged and fixed in an inner cavity of the metal shell through end covers at the two ends of the metal shell, wire outlet grooves are formed in the positions, corresponding to the electrode leading-out ends, of the end cover or the surface of the end of the metal shell, and the electrode leading-out ends penetrate through the wire outlet grooves and are in sealed connection with the end cover or the metal shell. The heating plate is safe, insulatedand efficient in heat conduction, has enough impact strength, and can be suitable for household electric heating products of different types.

Description

technical field [0001] The invention relates to the field of graphene heating, in particular to a graphene heating plate with an encapsulation structure. Background technique [0002] Nowadays, household appliances with heating function are very popular and widely used; their energy efficiency and durability are gradually valued by users and the industry. At the same time, small and concise appearance design is also the current industry trend. [0003] At present, many household electric heaters use electric heating wire or PTC heating tube heating technology. Such electric heating cores are often overheated and need to be packaged with a large amount of high-temperature-resistant heat-insulating materials (ceramics, etc.), which will inevitably reduce their heat conduction efficiency. , The energy efficiency is low. Due to the long-term internal high temperature, its service life is also greatly reduced. At the same time, a large amount of high-temperature-resistant heat-in...
