Plate heat exchanger

摘要: Plate heat exchanger in the form of several plates (1) placed close to and sealed against each other having pressed-out ridges (4) heating surface relative plate order provide two different flow passages same exchanger. The according invention consists identically like (1), packing groove (9) which has its bottom central plane (1). is further divided into at least area portions (5-8), one portion (5) an angle (α 1 ) symmetry axes (X Y, respectively) lying plane, from (β formed by (6) with that or more included are turned 180° about said (x, Y) starting orientation
