Abstract

In a plate heat exchanger for evaporation of a liquid by means of a heat emitting vapor every second plate interspace forms an evaporation passage (28) and the rest of the plate interspaces form condensation passages (30). Aligned openings (16) in the plates form an inlet channel through the plate heat exchanger for introduction of evaporation liquid into the evaporation passages (28). For enabling use of a large inlet area of each condensation passage (30) and a large outlet area of each evaporation passage (28) the plate heat exchanger is arranged in a container (1), the interior of which is divided in two chambers (6, 7) by the plate heat exchanger itself and a partition (5). Sealing means (13, 26) are arranged in the plate interspaces in a way such that the evaporation passages are closed from one chamber (6) but communicate with the other chamber (7) along the edges of the plates, whereas the condensation passages (30) communicate with said one chamber (6) along the edges of the plates but are closed from the other chamber (7).
