摘要

A heat exchanger plate for a plate heat exchanger (12) includes 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. The plate comprises a first port for a first medium, and at least a second port and a third port for a second medium. The plate further comprises a first sealing arranged on the second side around the first port, a second sealing arranged on the second side at a circumference of the plate, and a closed third sealing arranged between the first and second sealings to form a first heat transfer area and a second heat transfer area separated from the first heat transfer area. The second port is arranged in the first heat transfer area and the third port is arranged in the second heat transfer area.
