Abstract

New evaporator for absorption refrigerators formed by three groups of elements located in superimposed planes. The upper plane consists of a thick, long tube curved in loops, one end of which is lowered to join with the element of the lower plane, and the other end of which is lowered to initiate the element of the intermediate plane. The intermediate plane element is a continuation of the upper tube; It is folded into a long loop covered with cooling fins. The element of the lower plane constitutes the temperature changer: it consists of two wide concentric tubes, bent at right angles if necessary for the arrangement between the other components of the refrigerator. The external tube at one end receives the graft from a tube that rises from the reservoir of the apparatus and at the other end receives the graft from one end of the fin-covered tube of the intermediate plane; the inner tube, concentric with the previous one, receives at one end the tube coming from the absorber and at the other end it is connected with the said tube that goes down from the end of the loop of the upper plane. Both concentric tubes carry at intervals, placed under pressure, metal disks, cut into alternating segments, whose purpose is to make winding the path of the gases that circulate through them and increase the heat exchange surfaces. A thin tube, coming from the condenser of the apparatus, lowers and adapts to the external lower surface of the temperature changer and then ascends towards the element of the upper plane; said tube is externally welded to the ends of the loops of said upper plane and ends up grafting at the beginning of the loop whose branch is attached to the inner tube of the temperature changer.
