Device for minimising an undesired fluid overflow from a first sector to a second sector and heat exchanger system comprising a device of this type

摘要

The invention relates to a measure for minimising an undesired fluid overflow from a first sector (1) to a second sector (2) that are separated by a non-fluid tight partition (3), a first pressure (P1-1) prevailing in the first sector (1) and a second pressure (P2-1) that is lower than the first pressure (P1-1) prevailing in the second sector (2). An intermediate chamber (4) is located next to the partition (3), said chamber separating the two sectors (1, 2). A delivery unit (5) is designed to deliver fluid from the intermediate chamber (4) to the first sector (1) in order to produce a negative pressure in the intermediate chamber (4) in relation to the first pressure (P1-1) that prevails in the first sector (1), the pressure (P4-1) produced in the intermediate chamber (4) being equal to or greater than the second pressure (P2-1) prevailing in the second sector (2).
