Abstract
A heat exchanger is provided for a motor vehicle air-conditioning system with an inner tube and with an outer tube, which at least in regions encloses the inner tube in the region of a line portion subject to forming an intermediate space in tube longitudinal direction through which a heat exchanger medium can flow. The intermediate space at least in portions is subdivided into at least three flow channels with at least three webs running in tube longitudinal direction, which open into a distribution or manifold space formed through radial expansion of the outer tube, in which the webs compared with the line portion have a smaller extension in radial direction.
