USE - Method for preparing modified graphene fluoroplastic heat exchanger. ADVANTAGE - The method for preparing modified graphene fluoroplastic heat exchanger helps in improving applicability of heat exchanger, has good thermal conductivity, which greatly improves heat exchange performance of heat exchanger. DETAILED DESCRIPTION - Preparing modified graphene fluoroplastic heat exchanger involves preparing modified graphene fluoroplastic raw materials, fins, seals and graphene coatings required for manufacture of heat exchangers, and calculating modified graphene fluoroplastic raw materials required for heat exchangers of different sizes and specifications weight; selecting heat exchangers of different specifications to make molds, and complete inspections of molds to ensure integrity and cleanliness of molds, ensuring quality of heat exchangers produced, after inspection is completed, applying release agent on surface of molds; injecting modified graphene fluoroplastic raw materials into heat exchanger mold, and injecting raw materials in high temperature environment, cooling entire heat exchanger mold to form heat exchanger, molding, taking out modified graphene fluoroplastic heat exchanger and check defects on the surface of modified graphene fluoroplastic heat exchanger, when produced heat exchanger has burrs, then needs to cutting with cutter at same time; processing burrs, performing pressure test to check air tightness of different joints of modified graphene fluoroplastic heat exchanger, when air leakage is present, then needs to reworked and repaired, when air tightness is good, then no air leakage, and user check size of heat exchanger which is in normal error range according to requirements of drawing; cleaning outer surface of heat exchanger, spraying and drying, packaging, labeling and leaving factory.
