Title:
SYSTEM FOR OPTIMIZING THE DISTRIBUTION OF THE COOLANT FLUID IN A HEAT EXCHANGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/092587
Kind Code:
A8
Abstract:
A system is described for optimizing the distribution of the coolant fluid in a heat exchange device (10) of the type comprising a plurality of elements (12) arranged alongside one another and in hydraulic connection with one another. The elements (12) are internally provided with a first series of channels for the circulation of a first fluid, or coolant fluid, consisting of a biphase liquid/vapour mixture, and with a second series of channels for the circulation of a second fluid, or fluid to be cooled, capable of exchanging heat energy, through the walls of the elements (12), with such coolant fluid. The first series of channels is provided with a first inlet duct (14) for the coolant fluid and with a first outlet duct (16) for such a coolant fluid, whereas the second series of channels is provided with a second inlet duct (18) for the fluid to be cooled and with a second outlet duct (20) for such a fluid to be cooled. Along the first inlet duct (14) for the coolant fluid, upstream of the elements (12), there is at least one flow pattern modifying device (22) of the biphase liquid/vapour mixture, provided with at least one element (24; 32) capable of at least partially occluding such a first inlet duct (14) for the coolant fluid, so as to modify, according to a predetermined shape, the passage section of such first inlet duct (14) and optimize the distribution of the coolant fluid entering the heat exchange device (10), preventing the oversupply with coolant fluid of the first channels of the heat exchange device (10) arranged at such first inlet duct (14).
