New regenerator design for cryocoolers.

Author(s) : RÜHLICH I.

Summary

The comparison of different heat transfer surfaces shows a large potential to improve regenerators, concerning their ratio between pressure drop and heat transfer. With the use of computational fluid dynamics, shapes and arrangements of matrix elements were investigated systematically. The optimum geometry consists of slim elements in flow direction in a staggered overlapping arrangement. Such regenerators could provide equal thermal performance as stacked screens with up to five times lower pressure drop.
