Abstract (en)
[origin: WO2017121951A1] The invention relates to a cabinet used for freezing or storing food, medical or biological products, using a cryogenic fluid as cooling fluid, said cabinet being of the type that is: provided with one or more convection fans located in the enclosure of the cabinet and capable of moving the air inside the cabinet and thus of contributing to the thermal exchange that occurs therein; and provided with a system for extracting the gases formed in the enclosure of the cabinet due to the vaporisation of said cryogenic fluid, said extraction system including an extraction tube (1) connecting to one wall of the cabinet and linking the enclosure to the outside; characterised in that it includes a flap (2), located on said wall, at the point where the extraction tube enters the cabinet, and extending into the cabinet, the shape, position and direction of said flap making it possible to divert all or part of the turbulence (3) created by the or said convection fans towards the extraction tube.
