Abstract (en)
[origin: EP2631585A2] A heat exchanger is provided comprising a plurality of pairs of heat exchanger plates (1a) formed of sheet metal having a three-dimensional structured pattern, a first flow path being defined within the plurality of said pairs and a second flow path being defined between said pairs, each plate (1a) having at least one through-opening. It is intended to have a solid connection between adjacent heat exchanger plates (1a, 1b, 1c) in the area of the through-opening. To this end said through-opening is surrounded by tongues (10, 12, 13) cut from the area of the through-opening and bend out, wherein the tongues (10, 12) of one plate (1a, 1b) are inserted into the through-opening of a neighbouring plate (1b, 1c).
