The drycube contains a bottom and a lid, between which a spiral tape with several turns is vertically arranged, the outer of which is hermetically fixed between the bottom and the lid, and all other turns have a lower height and are evenly spaced to its center, where a spigot is installed, which is placed above the inner surface of the bottom so that it overlaps the level of the lower edge of the spiral tape, which has a gap with the bottom. The spiral tape with the upper edge of all the inner turns is hermetically fixed to the lid, and the last turn – to the bottom near the protrusion of the nozzle, and the outer turn has a flat bend, on which there is a fitting for connecting the dry cooler to the refrigerator, between the turns of the spiral tape there is a regular nozzle, and the tightness of all connections is performed by soldering or welding.
