Abstract

Abstract The exchanger tube comprises at least three concentric cylinders (1a, 1b, 1c) defining annular spaces (2a, 2b) in which circulate respectively the fluids between which the thermal exchanges are to be brought about, the said annular spaces comprising a plurality of radial ribs (3) interconnecting with the said cylinders (1a, 1b, 1c). The radial ribs (3) are disposed - in the annular spaces (2a, 2b) - in line with one another and are thermally integral with the walls of the cylinders (1a, 1b, 1c) which they connect, and consist of the same material as the material making up the said cylinders. <IMAGE>
