The invention relates to a plate package for a heat exchanger device, wherein the plate package (200) includes a plurality of heat exchanger plates (100) of a first type (A) and a plurality of heat exchanger plates (100) of a second type (B). At least the heat exchanger plates (100) of the first type (A) comprise, along at least a section of the opposing side portions (105), a draining channel flange (109). The draining channel flanges (109) are oriented in one and the same direction such that a draining channel flange (109) of a first heat exchanger plate (100) of the first type (A) abuts or overlaps a draining channel flange (109) of a subsequent heat exchanger plate (100). The draining channel flanges (109) form outer walls to the outer draining portions (DP) thereby transforming the outer draining portions (DP) into draining channels (111). The invention also relates to the use of such plate package in a heat exchanger device and also a heat exchanger device as such.
