▎ 摘　　要

NOVELTY - The evaporator has a refrigerating pipeline (1) fixed with a radiating fin. A surface of the refrigerating pipeline and the surface of the radiating fin are coated with graphene heat dissipation slurry (3), where coating thickness of the graphene heat dissipation slurry is in a range of 1-30 micro-meter, ratio of the area of the graphene heat dissipation slurry coated on an evaporator to an area of an entire evaporator is about 1 : 3, and ratio of the area of the graphene heat dissipation slurry coated on the evaporator to an area of the entire evaporator is about 2:3. USE - Evaporator for a refrigerator defrosting device (claimed). ADVANTAGE - The evaporator is coated with graphene heat dissipation slurry so as to enhance ability to absorb heat from a defrost heater during defrosting. The evaporator improves energy utilization efficiency, and reduces product energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a refrigerator defrosting device. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of an evaporator for a refrigerator defrosting device. Refrigerating pipeline (1) Graphene heat dissipation slurry (3)
