Apparatus for cooling and dehumidifying gases, method for cooling and dehumidifying gases and vehicle with a fuel cell system and a device for cooling and dehumidifying fuel cell exhaust air

摘要

A device (2) for cooling and dehumidifying gases has a first hollow body (4) with a gas inlet (6), a gas outlet (8) and a condensate drain (10), a second hollow body (14) with a coolant inlet (20) and a coolant outlet (22) and a drive unit (32, 42). The first hollow body (4) at least partially encloses the second hollow body (42). One of the first hollow body (4) and the second hollow body (14) is rotatably mounted relative to the other hollow body (4, 14) and has at least one vertebral body (28) which extends in the direction of the other hollow body (4, 14) . The drive unit (32, 42) can be coupled to the rotatably mounted hollow body (4, 14) to rotate it. In this way, a single-stage device for cooling and dehumidifying gases containing water vapor is realized, which has a particularly low structural space requirement and a particularly low weight. The device (2) is thus particularly suitable for use in vehicles, in particular aircraft.
