Abstract
Official abstract text for this publication.
A connection device of a double-walled heat exchanger tube is provided, in particular for the heat exchanger of a motor vehicle air conditioning system. The heat exchanger tube has an outer tube and an inner tube that runs coaxially inside the outer tube spaced radially apart from it. The connection device further has a fitting for accommodating radially overlapping end sections of the inner and outer tube. The outer and inner tubes according to the invention are at least sectionally joined together without soldering in the area of the fitting, and with the fitting.
