Abstract:
A plate heat exchanger comprising a plurality of identical corrugated heat exchanger plates, each of said identical corrugated heat exchanger plates of said plurality having a respective central plane and being asymmetrical in cross section relative to said respective central plane,wherein said corrugated heat exchanger plates are arranged next to each other in a tightly sealed arrangement and alternating corrugated heat exchanger plates are inverted so that at least one of said corrugated heat exchanger plates has (a) a first corrugated heated surface contacting a first corrugated heated surface of a first adjacent one of said corrugated heat exchanger plates to define smaller cross-sectional area flow paths therebetween and (b) a second corrugated heated surface contacting a corrugated heated surface of a second adjacent one of said corrugated heat exchanger plates to define larger cross-sectional area flow paths therebetween, said larger cross-sectional area flow paths being separated from said smaller cross-sectional flow paths.
