Abstract
A detector, in particular an IR detector in the seeker head of a guided missile, is cooled with expanding gas generated by depressurizing a pressurized fluid. A mixture which forms a positive azeotrope, including argon or nitrogen as a main component and at least one alkane as a secondary component, is expanded as the fluid. The composition is preferably in the region of a eutectic mixture in order to avoid a component freezing adjacent to the expansion nozzle. This makes it possible to considerably extend the life of the cooler in comparison to that when using pure cooling gases such as nitrogen or argon, and to cool the detector down more quickly, subject to the same constraints.
