NOVELTY - The utility model relates to the technical field of refrigerator production, specifically to an ice chest back coil heat conduction heat insulation layer, comprising a graphene slurry layer; aerogel insulating felt layer and foaming layer; the graphene slurry layer is set on the top surface of the aerogel insulating felt layer; the foaming layer is set on the bottom surface of the aerogel insulating felt layer; the top surface of the graphene slurry layer is provided with a back plate; the graphene slurry layer is embedded with a S-shaped coil pipe; the outer wall of the coil pipe is tightly jointed with the back plate. The utility model uses graphene slurry as heat exchange medium to increase heat exchange area, the whole back plate becomes the main body of heat exchange, which greatly improves the heat exchange effect, solves the problem that the back plate and heat exchange coil pipe because contact area is not enough and heat exchange is hindered; At the same time, the heat exchange medium is reinforced with air gel felt to enhance the heat insulating effect, so as to improve the refrigerating effect of the refrigerator/refrigerator, so as to reach the purpose of saving energy and low consumption.
