FIELD: heat engineering.
SUBSTANCE: heat exchanger tube is proposed, containing a flat body with parallel internal partitions made in one piece. The body is made of aluminium in the form of a parallelepiped, the small side edges of which are rounded, and the outer surface of the large side faces contains corrugation in the form of parallel ribs. The said body contains an external coating of a material comprising a combination of a barium-containing component and graphene.
EFFECT: improved efficiency of communication.
