Abstract (en)
[origin: WO2022148666A1] Regenerator (1) for a cryo-cooler with helium as a working gas and as a heat-storing medium, with at least one cell (2) with cell walls (4) which enclose a cavity (6) that has a number of sub-cavities (6-i). The sub-cavities (6-i) are connected to one another by way of at least one connecting channel (12) and, with the exception of the at least one connecting channel (12) to other sub-cavities (6-i), are enclosed by the cell walls (4). The cavity (6) of the at least one cell (2) is filled with helium gas as a heat-storing material. The regenerator also has flow channels (10) for helium as the working gas, which are formed between the individual sub-cavities (6-i) and have a pressure-equalizing opening in the form of a capillary (8), which passes through the cell walls (4) and forms a permanently open connection between the helium as the working gas outside the cavity (6) and the helium as the heat-storing material inside the cavity (6). In their interior, the sub-cavities (6-i) have supporting elements (14), which provide mutual support for the cell walls (4) delimiting a sub-cavity (6-i).
