(57) A heat exchanger is provided comprising a stack of a plurality of pairs of heat exchanger plates (1a, 1b, 1c) formed of sheet metal having a three-dimensional structured pattern, a first flow path being defined within said pairs and a second flow path being defined between said pairs, each plate having at least one through-opening, an outermost plate being an endplate.
It is intended to facilitate the connection of the heat exchanger to external fluid lines.
To this end the through-opening of at least said endplate (1a) comprises a raised edge forming a flange (10).
