Heat exchanger tube and heat exchanger comprising such a tube

摘要

The tube (100) has a folded wall defining a housing. An internal separator is inserted into the housing. The internal separator defines a set of fluid passage channels (136). The tube is configured such that a clearance between the wall and the internal separator is filled along length of a beam (110). The internal guide is corrugated, and includes a dish at a top part (132) of the separator, where the dish is in contact with the wall. An independent claim is also included for a method for obtaining a heat exchanger tube.
