▎ 摘　　要

NOVELTY - The heater has an insulating outer shell (1) whose side is fixedly connected with a water inlet pipe (3). Another side of the insulating outer shell is fixedly connected with a water outlet pipe (5). An inner part of the insulating outer shell is equipped with U-shaped micro-channel core (2). A back side of the insulating outer shell is fixedly connected with a hanging rack (6). An inner side of the water outlet pipe is equipped with an electric control temperature adjusting valve (4). The U-shaped micro-channel core comprises multiple inner tooth micro-channel plates. An upper end of a collecting pipe is provided with a cold water inlet port. A side of the collecting pipe is provided with a hot water outlet port. An inner tooth micro-channel plate and the collecting pipe are made of Aluminum materials. USE - Flat U-shaped micro-channel graphene heating water heater. ADVANTAGE - The heater can heat the inner tooth micro-channel plate through a graphene heating membrane, and reduces loss of the heat generated by graphene electric heating membrane through an ultra-conducting film for quickly heating cold water in the inner tooth micro-channel plate, prevents redness, burning and fire so as to avoid occurrence of explosion accident. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a U-shaped micro-channel core processing method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a flat U-shaped micro-channel graphene heating water heater. Insulating outer shell (1) U-shaped micro-channel core (2) Water inlet pipe (3) Electric control temperature adjusting valve (4) Water outlet pipe (5) Hanging rack (6)
