Abstract

The flat tube block heat exchanger has at least one flat tube (1), which is shaped at least at one end section (1a) to open into a connection zone. The shaped end section of the flat tube is separated into a number of end part-sections (4a,4b) by one or more longitudinal dividing lines (3), with a twist towards its neighboring end section (1b), so that the facing flat sides (5a,5b) lie against each other in the connection zone.
