Abstract (en)
[origin: FR2700383A1] Heat exchanger has an outer envelope (28) and a bundle envelope (26) with a common vertical axis and between them forming an annular space (30). Sec. fluid supply means is located in an upper area of annular space (30). Supply pipe (44) traverses outer envelope (28) and communicates with the sec. fluid supply means. Overflow or weir is placed in the upper area of the annular space (30) and extends over at least part of the circumference of space (30). Overflow has a horizontal upper edge.Supply pipe (44) issues into the overflow entirely at a level below the level of the edge. Deflecting wall is positioned in front of the edge and extends downwards and obliquely below the edge. This is so that sec. flow admitted into the overflow by the supply pipe (44) and which is discharged over the edge, flows downwards into the annular space (30) along the deflecting wall
