New regenerator types for cryocoolers.

Neuer Regeneratortyp für Kryokühler.

Author(s) : RÜHLICH I., QUACK H.

Summary

A comparison of various heat-exchange surfaces reveals a great potential for improving regenerators in terms of pressure loss during heat exchange. A digital flow simulation was developed in order to calculate various regenerator geometries, with a view to determining the parameters of their matrices, which affect the relationship between pressure loss and heat transfer. Based on the findings, a geometry was developed with performances similar to currently used wire-sieve generators, but with up to four times less pressure loss.
