Cirkulær pladevarmeveksler

摘要

The invention relates to a heat transfer plate (10) and a circular plate heat exchanger (1) comprising such a plate. The heat transfer plate (10) comprises at least two holes (11, 12) which form inlet or outlet passages for heat transfer media. The heat transfer plate (10) comprises grooves in its plane and ridges (18) therebetween, along which grooves a heat transfer medium is intended to flow between said holes. The grooves and/or ridges (18) therebetween are at least partly curved parabolas or hyperbolas which form several identical sectors on the circular heat transfer plate (10).
