Värmeöverföringsplatta, plattpaket samt plattvärmeväxlare

摘要

A heat transfer plate for a plate heat exchanger including a number of ridges ( 210 ) and troughs ( 220 ) which have been pressed into the plate, the heat transfer portion of the plate having a plurality of juxtaposed rows ( 200 ) of the ridges ( 210 ) and troughs ( 220 ). The rows ( 200 ) of ridges ( 210 ) and troughs ( 220 ) are separated from each other by essentially plane channel portions ( 240 ). Each row ( 200 ) presents alternating elongated ridges ( 210 ) and elongated troughs ( 220 ) which extend along a main flow direction (F). The transition between each ridge ( 210 ) and an adjacent trough ( 220 ) in the same row ( 200 ) is formed by a transition portion ( 230 ) which is inclined relative to the central plane (P 1 ) of the plate ( 1 ). The heat transfer plate is used in a plate pack for a plate heat exchanger.
