Abstract
Regenerator for a cryogenic system has lead sphere 58 packing and has grooves 54 and 56 in the regenerator walls to prevent gas bypass. Felt packing 66 between screens 64 and 68 causes continued compression of the regenerator packing as it changes size due to temperature changes. Gas spaces between the regenerator spheres is maintained low and regenerator sphere damage due to high intersphere loading is minimized.
Claims15
A thermal regenerator comprising:
- a wall enclosing a regenerator space with an inlet at one end of said wall and an outlet at the other end of said wall to define a flow direction, grooves in said wall, said grooves having a width, said grooves being oriented at an angle with respect to the flow direction;
- regenerator packing positioned within said regenerator and constrained by said walls, said regenerator packing being formed of discrete members which can exchange heat with gas passing through said regenerator packing, said discrete members having a major dimension at least as small as the width of said grooves.
