A heat exchanger (100) of flooded type, comprising: a primary tube bundle (10), inside which a first "hot" operating fluid to be cooled down flows; a skirt (1 ), circumscribed to the primary tube bundle (10), which receives a second "cold" operating fluid which laps against the primary tube bundle (10) in order to subtract heat to the first operating fluid, which second operating fluid flows inside the skirt (1) along to a vertical longitudinal direction orthogonal to the development of the tubes of the primary tube bundle, and wherein the skirt (1) has a prevalent development dimension (L) along the flow longitudinal direction of the second operating fluid; and nozzles (113) for delivering the secondary operating fluid inside the skirt, wherein an alternative configuration is provided using only the second operating fluid flooding the skirt by entering from a side inlet (8), without the presence of the above-mentioned nozzles, and an additional configuration using only the nozzles but not such side inlet (8). |
