<p>In a heat exchanger of falling film type comprising heat exchange plates with area enlarging corrugation forming ridges and valleys extending in the falling film direction, repeated redistribution of the falling film is brought about by having the ridges and the valleys extending continuously within each of a number of zones formed one after the other in the falling direction, whereas the ridges and the valleys with regard to two consecutive zones are laterally displaced in relation to each other such that the ridges and the valleys, respectively, in one zone extend in alignment with the valleys and the ridges, respectively, in a consecutive zone.</p> |
