Abstract
Exchanger having a tube and fin bundle and comprising: a duct (4) through which a cryogenic fluid can flow between a fluid inlet (1) into the exchanger and a fluid outlet (2) from the exchanger; and a system of flat, continuous and parallel fins (3) through which said duct passes inside the exchanger, it being possible for air (12) to circulate within the exchanger by passing through channels delimited by the space between the duct and the parallel fins. The exchanger is characterized in that it comprises at least two independent ducts (10a, 10b) for the circulation of cryogenic fluid within the exchanger.
