Abstract
In a heat exchanger such as a steam generator equipping a nuclear power station the secondary fluid is injected into the upper part of an annular space (30) formed between an outer envelope (10) and a bundle or core envelope (26) having a common vertical axis. Injection takes place by means of a supply pipe (44), which issues into an overflow or weir (62). The latter has an upper horizontal edge (64) from which the secondary fluid is discharged onto a deflecting wall (54). The secondary fluid flows along this wall towards the bottom of the annular space (30). A device (60) for trapping migrating bodies can also be placed in the overflow (62) or between the latter and the deflecting wall (54).
