Abstract: A plate heat exchanger is disclosed. The plate heat exchanger of the present disclosure includes: a first plate having a wavy first heat transfer surface through which a first fluid flows; a second plate having a wavy second heat transfer surface through which a second fluid flows, the first plate and the second plate being stacked on top of each other; and ribs provided at a portion of the first heat transfer surface, wherein the wavy first heat transfer surface has alternating ridges and grooves; and the ribs project from the grooves toward the ridges in the first heat transfer surface, to come into contact with the second plate.
