Abstract:
A rotary heat exchanger through which a first fluid flow—an outside air or inlet air flow, for example—and a second fluid flow—an exit air or outgoing air flow, for example—can flow in a counterflow configuration, has a rotatably mounted rotor ( 5 ) that has a first flow sector for the first fluid flow and a second flow sector for the second fluid flow through which the rotor ( 5 ) passes during a rotation, a frame in which the rotor ( 5 ) is rotatably supported, and a sealing assembly ( 9 ) by means of which an inflow side of the first fluid flow and an outflow side of the second fluid flow can be separated from the outflow side of the first fluid flow and from an inflow side of the second fluid flow, respectively. In order to simplify the sealing assembly, with the aim being that a reliable seal between the inflow and outflow sides of the two fluid flows be automatically ensured during operation of the rotary heat exchanger, it is proposed that the sealing assembly ( 9 ) have a first seal ( 12 ) that bears sealingly against the side of a partition ( 10 ) directed upstream into the first fluid flow ( 2 ), and a second seal ( 13 ) that bears sealingly against the side of the same partition ( 10 ) directed upstream into the second fluid flow ( 3 ).

Claim (Index 13):
A rotary heat exchanger comprising:\n a frame; a partition in the frame having axially oppositely directed faces, defining a circular opening centered on an axis, and defining a first flow sector through which a first gas stream flows in one axial direction through the opening and, angularly offset therefrom, a second flow sector through which a second gas stream flows in an opposite axial direction through the opening; a rotor rotatable about the axis in the opening of the frame, constructed such that the gas streams in the flow sectors can flow axially oppositely through the rotor and exchange heat therewith, and having a radially outwardly directed cylindrical edge surface spacedly juxtaposed with a circular inner edge of the opening; and respective first and second annular L-section seals each extending circumferentially around the rotor and each having two mutually perpendicular parts of which one part extends axially and is fastened to the edge surface of the rotor and another part extends radially and bears axially on the partition around the opening thereof, whereby pressure in the flow sector presses the axially and oppositely against the partition.
