A plate heat exchanger comprising a plurality of plates ( 12,13 ) which are stacked against each other and which are of a first and second type in order to form flow channels for a first and second medium. The plates form a heat exchanger block ( 2 ) with an upper side and a lower side and with two opposite side surfaces ( 10 ) and front faces ( 9 ). The first flow channels are peripherally sealed for the first medium and are fluidically connected to distributor and collector channels which are arranged in a vertical position with respect to the plate plane and which lead into inlet and outlet connection pieces ( 6,7 ) which are respectively arranged on the upper side and/or lower side ( 3,11 ). The second flow channels are open at the front surfaces ( 9 ) thereof and are sealed at the side surfaces ( 10 ) thereof. The open sides ( 9 ) form an inlet and outlet plane for the second medium.
