A HEAT EXCHANGER PLATE AND A PLATE HEAT EXCHANGER HAVING IMPROVED JOINING PLACES AS WELL AS MANUFACTURING METHODS THEREOF

摘要

The invention relates to a heat exchange plate (1) containing a lower plate plane (U) and an upper plate plane (U) for a plate heat exchanger (10) and a manufacturing method of a plate heat exchanger (10). The invention also relates to a heat exchanger plate (1) for a plate heat exchanger (10) containing more than one heat exchanger plates (1), and a plate heat exchanger (10). The invention particularly relates to forming forms (A) around inlet and/or outlet holes (5, 6) of a heat exchanger plate (1) extending from lower plane (U) to upper plane (O).
