HEAT EXCHANGER WITH ULTRASOUND GENERATORS

摘要

A heat exchanger (10) comprises a plurality of fluid flow channels (11) and a header (12) fed with a stream (F) of a two‑phase fluid having two phases (PL, PV), one of them being the liquid phase (PL) and distributing said stream (F) to the plurality of channels (11). Each channel (11) has an inlet opening into the header (12). The heat exchanger (10) comprises at least one main ultrasound generator (13) associated with at least one of said channels (11) and configured to generate a deformation (14) of a free surface of said liquid phase (PL) extending close to the inlet of the associated channel (11), notably toward the inlet of the associated channel (11).
