Plate heat exchanger plate for plate heat exchanger, plate heat exchanger comprising such a plate, heating device comprising said plate heat exchanger, and method for heat exchanger

摘要

The present invention relates to a heat exchange plate 17 for the plate heat exchanger 12, and includes a first surface, a second surface, and a center point P, and a virtual center axis A passes through the center point and the plane of the plate 17. The plate 17 comprises a first port 30 for the first medium and at least a second port 31 and a third port 32 for the second medium, and The first sealing 35 disposed on the second surface around the first port 30, the second sealing 36 disposed on the second surface at the periphery of the plate 17, and the first heat exchange region 38. And a closed third sealing 37 disposed between the first and second sealings 35, 36 to form a second heat exchange region 39. The second port 31 is provided in the first heat exchange area 38 and the third port 32 is provided in the second heat exchange area 39. The invention relates to a plate heat exchanger comprising such a plate and a heating device comprising such a heat exchanger.
