Plate heat exchanger, method of operating a plate heat exchanger and method of manufacturing a plate heat exchanger

摘要

A plate heat exchanger (1) for a process plant (26), with a connection device (9-18), in particular an inlet header, for supplying a liquid phase (FP) of a fluid (A-E) to be evaporated to the plate heat exchanger (1), a Heat exchanger block (2) which has a plurality of heat transfer passages (32) arranged one above the other in a depth direction (z) of the heat exchanger block (2), each heat transfer passage (32) having a distribution opening (36) provided in the heat exchanger block (2) for distributing the liquid phase (FP) is assigned to the heat transfer passage (32), a pressure loss element (52, 52 ', 52 ") being arranged at each distributor opening (36) in order to provide a To generate pressure loss, wherein each pressure loss element (52, 52 ', 52 ") has a perforation (60, 60', 60") with a plurality of openings (61, 61 ', 61 ", 62, 62', 62", 63 , 63 ', 63 "), and where the distances (b, b', b", c, c ', c ") of openings (61, 61', 61", 62, 62 ', 62 ", 63, 63 ', 63 ") of different pressure loss elements (52, 52', 52"), viewed along the depth direction (z), differ from one another.
