▎ 摘　　要

NOVELTY - The exchanger has a flanges fixed set at two sides of a shell. An inner side of the shell is provided with a plate bundle assembly. Left and right sides of the plate bundle assembly is fixedly connected with the shell. A lower end of the shell is provided with a dielectric inlet. An upper end of the shell is provided with a dielectric outlet. The shell is a rectangular-shaped shell. Left and right sides of the shell are connected with a ultrasonic contaminant transducer. The ultrasonic contaminant transducer is connected to an external ultrasonic power supply. USE - Oxidation graphene nano fluid based plate-shell heat exchanger. ADVANTAGE - The exchanger improves operation safety, guarantees device operation reliability and reduces maintenance cost. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an oxidation graphene nano fluid based plate-shell heat exchanger.
