Abstract
A heat transfer plate for a plate heat exchanger has a heat transfer portion ( ) having elevations and depressions ( ), a first port portion (G), a second port portion (H), first sealing portions ( ), and second sealing portions ( ). The plate has a symmetry line (S), which extends from a first edge ( ) to a second edge ( ) of the plate and in relation to which the plate's heat transfer portion, sealing portions and ports to be passed by each of the heat transfer fluids are symmetrically arranged. The elevations and depressions ( ), are located in such manner relative to the symmetry line (S) that when two identical plates are brought to abut against each other—one of the plates being rotated through 180 degrees about the symmetry line (S)—the elevations ( ) on the plates will form distance means between the plates in a large number of positions distributed over the heat transfer portions ( ) of the plates.
