PROCEDE DE FABRICATION D'UN ECHANGEUR DE CHALEUR A TUBES CONCENTRIQUES |
摘要 |
A method is provided for manufacturing a concentric-tube heat exchanger which includes at least a pair of concentric tubes disposed one within the other to form an annular longitudinally extending flow channel in which a plurality of heat transfer promoting fins reside. The method includes the step of applying a radially directed force to one of the pair of concentric tubes in sufficient magnitude to permanently deform the tube into engagement with the plurality of heat transfer promoting fins. |
