Patent ID: 10029800

Abstract:
The system comprises at least one evaporator device arranged around a tube inside which a hot fluid flows and, for each evaporator device, a respective conduit connected at its opposite ends to the evaporator device so as to form with the latter a closed circuit containing a two-phase fluid. Each evaporator device comprises a casing, having an inner wall in contact with the respective tube and an outer wall enclosing a cavity with the inner wall, and a separating member of porous material arranged inside the casing so as to divide radially the cavity into an inner cavity, extending between the inner wall and the separating member, and an outer cavity extending between the separating member and the outer wall. Each conduit is in fluid communication at its opposite ends with the inner cavity and with the outer cavity, respectively, of the respective evaporator device so as to allow fluid in vapor phase to flow out from the evaporator device and the fluid in liquid phase to flow back into the evaporator device, respectively.
