A plate heat exchanger comprising a pack of heat transfer plates (2) provided with inlet ports (9) forming an inlet channel (11) and with sealing means co operating with the plates to delimit first (13) and second flow passages in alternate plate interspaces. A first sealing area (17, 23) is located around the respective inlet port (9). The inlet channel (11) communicates with each first flow passage (13) by way of at least one inlet passage (15) while being blocked from the second flow passages by said first sealing area. The plates which form said first flow passage (13) have an essentially tight surface abutment against each other in a second sealing area (16) in connection to the respective inlet ports (9), and said inlet passage (15) is delimited by at least one of said heat transfer plates (2) between the at sealing area (17, 23) and the inlet port (9) of the heat transfer plate (2).
