Device for cooling material flows

摘要

The device (1) has an evaporation heat exchanger (5) for evaporating a condensed gas by heat exchange with a gaseous medium. The evaporation heat exchanger has an inlet (28) for the condensed gas and a delivery pipe (29) for evaporated gas, and has an inlet (33) and a delivery pipe (27) for the gaseous medium. The evaporation heat exchanger is mounted on a product cooling heat exchanger (6). The evaporation heat exchanger is equipped with a heat exchanger surface (24) for the heat exchange with the substance flow in the product cooling heat exchanger.
