1. A heat exchanger adapted to perform heat exchange between a supply air flow and an exhaust air flow, the heat exchanger comprising:
a heat exchange element in a prism shape;
a plurality of frame bars, each of the plurality of frame bars being attached to a corresponding side of the heat exchange element, the corresponding side extending along an axial direction of the heat exchange element; and
an end face plate adapted to cover at least partially an axial end face of the heat exchange element, and the plurality of frame bars are joined to the end face plate, wherein
the frame bars are joined to the end face plate in such a way as to be movable relative to the end face plate in the axial direction of the heat exchange element.
