Patent ID: 6962191

Claim:
A device for fixing and sealing a replaceable heat-exchanger cassette ( 10 ) in an air/air heat exchanger ( 20 ), wherein two spatially separated conducting areas are formed by separating strips ( 21 , 22 , 23 , 24 ) and the heat exchanger cassette ( 10 ), the device comprising: the air/air heat exchanger ( 20 ) having sealing receivers ( 32 a to 32 c ) in an area of separating strips ( 21 to 24 ), the heat exchanger cassette ( 10 ) resting against the sealing receivers ( 32 a to 32 c ) with sealing faces ( 11 a to 11 d ), and the air/air heat exchanger ( 20 ) having at least one movable slide ( 40 ) maintaining the heat exchanger cassette in the sealing receivers ( 32 a to 32 c ) under prestress, the slide ( 40 ) fastened on one of the separating strips ( 21 , 22 , 23 , 24 ) and having a bridging section with a seal ( 34 ) resting against an associated sealing face ( 11 d ) of the heat exchanger cassette ( 10 ), and the bridging section and the seal ( 34 ) bridging a transition area between a free end of the separating strip ( 24 ) and the heat exchanger cassette ( 10 ), the slide ( 40 ) having an opening shaped as an elongated hole acting as a slide guide, the opening aligned with a receiver in the separating strip ( 24 ) and a receiver of the eccentric lever ( 41 ), and a fastening screw ( 43 a ) passing through the opening of the slide ( 40 ) and the receivers of the separating strip ( 24 ) and the eccentric lever ( 41 ) and secured with a nut.
