Abstract
Abstract A regenerative heat exchanger. The rotor is an annular body and includes several rotationally symmetrical chambers which are separated from one another by walls, with the axially parallel dividing walls being permeable for the gaseous heat-dissipating or heat-receiving medium, and the radial dividing walls being permeable for the gaseous medium; heat-transferring elements for the regenerative heat exchange are arranged in the chambers accompanied by formation of a whirl layer during operation. The chambers have radial flow therethrough.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A regenerative heat exchanger, including a rotor which is in the form of an annular body and comprises a plurality of rotationally symmetrical chambers which are separated from one another, the formation and separation of said chambers being effected by axially parallel dividing walls and radially extending dividing walls, said axially parallel dividing walls being permeable for gaseous heat-dissipating and heat-receiving medium, and said radial dividing walls being impermeable for said gaseous medium; heat-transferring elements for the regenerative heat exchange being arranged in said chambers, said heat-transferring elements being accompanied by the formation of a whirl or fluidized layer during operation of said rotor.
Claim 2
Dependent Claim
