Abstract
The invention discloses a graphene oxide compound electronic radiator and relates to the technical field of radiators. A graphite oxide compound conducting adhesive prepared after grinding and mixing of graphene oxide suspension liquid, prepared through the key technology of arranging a graphene oxide compound conducting adhesive and by placing graphene oxide into purified water for ultrasonic treatment, and a compound, prepared by mixing nano-graphite powder, bamboo charcoal fibers, epoxy resin, dicyandiamide and dimethylformamide is smeared on the two sides of a gum-dipped glass cloth curing sheet and dried to make a heating layer; after electrodes are distributed on the two sides of the heating layer, the two sides of the heating layer are covered with high-temperature-resistant flame-retardant epoxy resin insulation protective layers respectively, a graphene oxide compound electronic finned radiator made after pressing-fit is carried out under 160 DEG C and 6 Mpa for 2 hours is subjected to trimming, wire bonding and frame installation, and the finished product, namely the graphene oxide compound electronic radiator is made. The graphene oxide compound electronic radiator is used for heating and is simple in process, good in effect, low in cost and convenient to popularize.
Description
technical field [0001] The graphene oxide composite electronic heater of the present invention relates to the technical field of heating; in particular, it relates to the technical field of graphene oxide composite electronic heater. Background technique [0002] Existing heating systems at home and abroad mainly include resistance wire heating, carbon fiber heating, and heating film heating. The above-mentioned known heaters have deficiencies, defects and disadvantages such as small temperature resistance range, short service life, poor mechanical properties, inconvenient use, low heating efficiency, large temperature difference between cold and hot spots, and inability to be made into high-power heating products. Based on the inventor's professional knowledge and rich work experience, as well as the unremitting pursuit of business excellence, on the basis of careful and full investigation, understanding, analysis, summary, and research on existing known technologies and cu...
