Abstract: 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.

Abstract: A plate heat exchanger has flow channels through which a first flow and a second flow pass in concurrent or countercurrent flow. The flow channels are formed for the first medium between individual plates (1) joined together to form in each case a pair (P) of plates, and for the second medium between pairs (P) of plates joined together to form a stack (S) of plates, wherein the individual plates (1) within an inlet region (E) have guide blades (2) which are formed by stamped embossments and protrude into the flow channel, wherein the guide blades (2) are formed in an arch-shaped manner with an inflow leg (21) aligned substantially parallel to the main flow direction and an outflow leg (22) aligned at an angle to the inflow leg (21).

Abstract: The invention relates to a method for heat energy transmission between a gaseous, warmer medium on one hand and a liquid, colder medium on the other hand. In order to provide an improved method for heat energy transmission, the invention suggests a method in which the liquid and the gaseous media are passed by each other using a plate heat exchanger, wherein the gaseous medium is cooled down and the water contained therein is condensed out, while the heat energy released due to condensation is transferred to the liquid medium.

Abstract: A plate heat exchanger including adjoining plates disposed adjacent one another and having peripheral grooves and channels alternately for media giving off heat and absorbing heat, seals made of an elastic material each being emplaced between the adjoining plates in the groove of one of the plates, attachment holes in each plate, and nipples on each seal insertable in the holes and with cross-sections different from the penetration cross-sections of the holes such that the nipples when inserted into the holes are not compressed about their entire circumference but only at spaced sites thereon at which the nipples project beyond the margin of the holes. The holes are defined by downturned edges which have radii and point in the insertion direction of the nipples into the holes.
