Method and press tool for fabricating a plate heat exchanger

摘要

The method involves producing individual plates (1) from a non-pressed plate blank by converting a tool with exchangeable mold elements to a converted tool that produces cross flow plates or countercurrent flow plates. The plate blank is pressed with the converted tool into the cross flow plate or countercurrent flow plate. Corresponding edges (12) and/or contact surfaces (13) and inflow cross-sections (Z1, Z2) and outflow cross-sections (A1, A2) are formed in main flow directions of two respective mediums. Distance between adjacent individual plates is determined. Independent claims are also included for the following: (1) a pressing tool for pressing individual plates for plate heat exchangers (2) a system for manufacturing individual plates for plate heat exchangers.
