An evaporator (1), for evaporating a liquid (4), particularly for a waste heat utilization device of an internal combustion engine, includes a plurality of channel plate arrangements (2) that are stacked in a stacking direction (3). A gas path (6) is formed between each pair of adjacent channel plate arrangements (2), through which a gas (7) can be conducted. The gas is used to supply the heat that is required to evaporate the liquid (4). Each channel plate arrangement (2) contains a liquid inlet (8), a steam outlet (9), and a channel (11) which connects the liquid inlet (8) and steam outlet (9) together and which forms a repeatedly-deflecting evaporation path (12) for the liquid (4) to be evaporated. Increased efficiency can be achieved if the channel (11) has, in an evaporation path (12) evaporation zone (14), a flowable cross-section (18) which increases in a direction of liquid (4) flow. |
