Abstract
An air-to-air heat exchanger, is provided that comprises a folded fin core formed from a continuous sheet of thermally conductive material that has been folded into alternating flat ridges and troughs; an insert overlay having an opening including two sets of uniform fingers, wherein each finger has a portion protruding into and essentially filling each trough on one surface of the folded fin core; an inset region between each finger portion and the end edges of each trough; a sealant within each inset region sealably attaching the insert overlay to the folded fin core; and an air flow divider plate. Heat exchanger components are also provided.
Claims16
An air-to-air heat exchanger comprising:
- a folded fin core including a plurality of troughs and ridges;
- a frame having peripheral rails that together define a central opening and a plurality of fingers extending from confronting portions of said peripheral rails, said frame being positioned in overlying relation to said folded fin core so that one of said plurality of fingers is sealingly received within each trough of said folded fin core;
- and
- an air flow divider plate positioned in overlying relation to said folded fin core and between said confronting portions of said peripheral rails.
An air-to-air heat exchanger comprising:
- a folded fin core including a plurality of substantially parallel, thin fin walls that are spaced apart from one another by alternating ridges and troughs so as to define a top face and a bottom face;
- a frame having a pair of spaced-apart confronting lateral rails and a pair of spaced apart longitudinal rails that together define said central opening;
- a plurality of fingers projecting inwardly and downwardly from an interior side of each of said lateral rails, wherein said frame is positioned in overlying relation to said folded fin core so that one of said plurality of fingers is sealingly received within each trough of said folded fin core;
- and
- an air flow divider plate positioned in overlying relation to said top face and between said lateral rails.
An air-to-air heat exchanger comprising:
- a folded fin core including a plurality of fin walls defining troughs and ridges therebetween;
- a folded fin insert positioned between said fin walls;
- a frame having peripheral rails that together define a central opening and a plurality of fingers extending from confronting portions of said peripheral rails, said frame being positioned in overlying relation to said folded fin core so that one of said plurality of fingers is sealingly received within each trough of said folded fin core;
- and
- an air flow divider plate positioned in overlying relation to said folded fin core and between said confronting portions of said peripheral rails.
