Corrugated folded plate heat exchanger

A heat exchanger for supporting heat exchange between two high pressure fluid media flowing therein, said heat exchanger comprising:

• a core comprising a continuous sheet having continuous corrugations running angularly to the direction of said sheet, said core being folded to form a plurality of folds, said continuous sheet having extreme ends that are not folded;
• a pair of symmetrical elongated housing shells, each having a respective pair of side edges, that compress said core when joined at said respective pair of side edges such that said plurality of folds conform to the shape of an interior wall formed by the joined elongated housing shells, said extreme ends of said folded sheet being captured by said joined symmetrical elongated housing shells along said respective pair of side edges, said joined symmetrical elongated housing shells forming a heat exchanger housing;
• said housing having a first set of inlet and outlet ports for circulating a first medium through said housing and a second set of inlet and outlet ports for circulating a second medium through said housing;
• said compressed core forming alternating isolated channels within said housing without the need for any sealants, said alternating isolated channels comprising a first set of channels that is in fluid communication with said first set of ports and a second set of channels that is in fluid communication with said second set of ports, said first and second media forming parallel flows within said respective sets of channels;
• wherein the interior of each one of said first and second set of channels comprise crossed corrugations that are in contact with each other, said crossed corrugations not being joined together;
• and
• said core transmitting forces from differential internal pressures, caused by said first and second flowing media, to said housing.
