Abstract
Abstract A regenerator for effecting heat exchange between two fluids, one of which transfers heat to a mass within the regenerator while the other abstracts heat from this mass. The regenerator is provided with a portion in which a fluid, e.g. water, is condensed. The regenerator has stacked matrices, hurdles, baffles or stages of the heat-absorbing material which comprise corrugated sheets with the corrugations of the several stages being inclined at different angles to the axis of the regenerator. The angle between the longitudinal axis of the regenerator and the direction of the corrugation in the condensation stage is less than that in other stages.
