▎ 摘　　要

NOVELTY - The exchanger has a heat exchanger core body (1) provided with a first heat exchange plate substrate (2) alternatively overlapped with a second heat exchange plate (3). A top part of the first heat exchange plate substrate is installed with a cover plate to form a heat exchanger core body (4). The heat exchanger core body is fixedly connected with each other. A fluid flow passage and a gas flow passage are formed between the first heat exchange plate and the second heat exchange plate. USE - The anti-corrosion printed circuit board heat exchanger is useful for gas production. ADVANTAGE - The surface of the heat exchanger is coated with graphene film by vapor deposition method so as to perform anti-corrosion treatment to the heat exchanger. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the coating process for the corrosion-resistant printed circuit board heat exchanger for gas-liquid heat exchange. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of anti-corrosion printed circuit board heat exchanger.
