Abstract:The connection structure between a heat exchanger tube and a tube plate works great effects on the service life of the heat exchanger, and the rational selection of the connection structure in line with the technical conditions is an important link during the heat exchanger design. The type of the connection structure between the heat exchanger tube and the tube plate are to be discussed and determined,and the suitable selection basisunder different technical conditions is brought forward in this work.
Key words:heat exchanger tube; tube plate; connection |
