Abstract

A heat exchanger of flooded type, having:

a primary tube bundle, inside which a first “hot” operating fluid to be cooled down flows;a skirt, circumscribed to the primary tube bundle, which receives a second “cold” operation fluid which laps against the primary tube bundle in order to subtract heat to the first operating fluid,which second operating fluid flows inside the skirt along to a vertical longitudinal direction orthogonal to the development of the tubes of the primary tube bundle, and wherein the skirt has a prevalent development dimension (L) along the flow longitudinal direction of the second operating fluid; andnozzles 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, without the presence of the above-mentioned nozzles, and an additional configuration using only the nozzles but not such side inlet.
