A heat exchanger having manifolds in essentially parallel arrangement and having a special-section tube matrix which is arranged in a housing to project into a hot gas stream carried in the housing, the tube matrix being subdivided into sections and containing U-shaped reversal zones, where compressed air to be heated is admitted into the matrix via one manifold, is reversed in its direction and fed to the other manifold. The matrix sections are divided by transverse baffle walls. The ends of transverse supports extending around the tube matrix and the manifolds are connected to the housing in the vicinity of the U-shaped reversal zones, and the manifolds are supported in the housing for axial movement at both ends and are mounted rigidly on one support and axially movably on at least one further support. |
