摘要 |
A method of mechanically joining tubes to headers in tubular heat exchangers of a high density, high performance type. The headers are made of a heat recoverable metallic material and worked while in a martensitic state to be subsequently shrunk upon installed tubes. Procedural steps are carried out with particular regard to a header construction characterized by a multiplicity of closely spaced apart tube accommodating holes separated by relatively narrow ligaments in which working stresses are to be absorbed. |
