PROBLEM TO BE SOLVED: To prevent a fault of a conventional technology by providing a device capable of providing at least one dry cold gas stream. SOLUTION: This heat exchanger device is capable of delivering at least one pressurized dry gas stream cooled to an essentially constant temperature, wherein at least one gas stream circulates, at the level of the device, in a coil whose functional part is immersed in a liquid fraction of a second gas that is present in a chamber of a corresponding container, and at least a part of a wall of the container that delimits the chamber is in contact with a liquid fraction of a third gas to constitute a condensation surface for the second gas. A calorific power apparatus comprises a monitored variable heating means of a bath formed by the liquid fraction of residual gas in the container. The total calorific power released, on the one hand, by the circulating gas to be cooled and, on the other hand, by the heating means, is constantly kept approximately equal to the specified calorific power.
