Abstract: A heat exchanger comprises a shell having an elongated shape and a cylindrical geometry. A first fluid, fed through one or more first inlet pipes, flows inside the shell and a second fluid, fed through at least one second inlet pipe, flows inside the shell in order to perform heat exchange with the first fluid. The heat exchanger also comprises a fluid distributor assembly placed at the first inlet pipes. The fluid distributor assembly is provided with a first perforated plate, in turn provided with first through holes, and with at least one second perforated plate, in turn provided with second through holes. The second perforated plate is disposed parallel and downstream of the first perforated plate with respect to the flow direction of the first fluid flowing into the first through holes and the second through holes. Between the first perforated plate and the second perforated plate a hermetic seal device is disposed.

Abstract: There is described a heat exchanger comprising a plurality of tubes arranged parallel with each other in order to form one or more tube bundles axially inserted into a shell. A first fluid, fed through one or more first inlet nozzles flows inside the tubes and a second fluid, fed through at least one second inlet nozzle, flows inside the shell in order to perform the heat exchange with the first fluid through the walls of the tubes. Inside the shell two or more baffles are formed and arranged perpendicularly with respect to the centre axis of the shell. Between each baffle and the inner walls of the shell there is defined a corresponding window constituted by the cross-section for the passage of the second fluid, with a crossing direction parallel with the centre axis of the shell and the tubes, delimited by the free edge of the respective baffle on the one side and by the inner profile of the shell, at the intersection of the shell with the plane of the baffle, on the other side.
