Abstract

A heat exchanger, in particular an exhaust gas heat exchanger for a motor vehicle, has tubes through which a first fluid can flow and around which a second fluid can flow, and a headpiece. The headpiece includes a dual-walls structure in at least a part thereof and a distribution chamber that communicates with the tubes.
