Method for the sealed mounting of the end of a tube in a hole of a wall, and heat exchanger with a tube bundle made by implementing this method

摘要

The invention relates to a heat exchanger with a tube bundle having a non-circular transverse section, for example an oblong section 26 which is transformed, at the ends of the tubes, into a biconvex lenticular cross-section 28 by compression between two jaws 34 of identical shape.
