Abstract

A refrigerating device for supplying human beings with foodstuffs and/or drinks is improved in such a way that it can be transported in use, in particular in portable or movable containers in land vehicles, watercrafts and aircrafts. For that purpose, the device has a vortex tube (11) composed of a heat exchanger tubular section (5) with at least two tangentially arranged nozzles for a compressed air supply (2) and a cold tubular section (4) provided with a stop (3). The heat exchanger tubular section (5) is linked to the compressed air supply (2) through an air deflector (7) and carries on its outlet end a baffle plate (8) with several openings (9) distributed around its circumference.
