A heat exchanger plate (17) for a plate heat exchanger (12), comprising a first side, a second side and a centre point (P) through which an imaginary centre axis (A) extends in a direction perpendicular to a plane of the plate (17), wherein the plate (17) comprises a first port (30) for a first medium, and at least a second port (31) and a third port (32) for a second medium. The plate (17) further comprises a first sealing (35) arranged on the second side around the first port (30), a second sealing (36) arranged on the second side at a circumference of the plate (17), and a closed third sealing (37) arranged between the first and second sealings (35, 36) to form a first heat transfer area (38) and a second heat transfer area (39) separated from the first heat transfer area (38), wherein the second port (31) is arranged in the first heat transfer area (38) and the third port (32) is arranged in the second heat trans¬ fer area (39). The invention also relates to a plate heat exchanger comprising such plates and a device for heating comprising such a heat exchanger. |
