Abstract: A plate heat exchanger includes a stack of plate pairs arranged within a housing. Comb-like baffles extend into flow gaps between the plate pairs to direct a fluid flow in a sinusoidal pattern within the flow gaps. The flow gaps are divided into two sub-sets of flow gaps, preferably alternatingly arranged along the height of the stack. Legs of some baffles extend into a first sub-set but not into the second sub-set, while legs of some baffles extend into the second sub-set but not into the first sub-set. The baffles are arranged so that the sinusoidal pattern in the second sub-set is phase-shifted form the sinusoidal pattern in the first sub-set.
