A method la proposed for producing a plate heat exchanger with flow channels through which a first and a second medium flow, the flow channels formed for the first medium between individual plates joined together to form a pair of plates, and for the second medium between pairs of plates joined together to form a stack of plates. For a cost-effective production of countercurrent flow plates and cross flow plates within a single manufacturing plant, the individual plates are produced from a non-pressed plate blank, wherein first a tool is converted with exchangeable mold members for producing cross flow plates or countercurrent flow plates, and subsequently, the plate blank is pressed by the converted tool into a cross flow plate or a countercurrent flow plate, thereby forming corresponding edges and/or contact surfaces as well as inflow and outflow cross-sections. |
