Abstract

An evaporator for an absorption heat pump or a single coolant cooling process comprises a number of stacked plates provided with a pressed pattern to hold the plates on a distance from one another to form a heat exchanging strip, vapor leading spaces and outer walls, the heat exchanging strip being designed such that flow channels are formed by internal surfaces of the strip, said flow channels connecting a heat carrier inlet and a heat carrier outlet, wherein a coolant forms a falling film on external surfaces of the heat carrier channels by being provided above the heat carrier channels by a coolant inlet, wherein coolant being vaporized from the external surfaces by heat from a heat carrier flowing from the inlet to the outlet rapidly enters the vapor leading spaces. The vapor leading spaces are provided between the heat exchanging strip and the outer walls.
