PLATE HEAT EXCHANGER

摘要

The invention relates to a plate heat exchanger (10), in particular for exhaust heat transfer in motor vehicles, having a plurality of heat exchanger plates (12) which are arranged spaced apart from one another forming primary and secondary shafts (14; 16) for a primary medium and a secondary medium, wherein flow guiding elements (20) are arranged in each of the primary and/or secondary shafts (14; 16) which form at least one meander-shaped flow channel (24; 24a) for the primary or secondary medium in the shafts (14; 16). The flow guiding elements (20) are preferably formed by means of beads (26) on one or both heat exchanger plates (12) of the shaft (14, 16).
