Inventor(s) include Girardi, Simone; and Fiorese, Federico.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Disclosed is a heat exchanger (1,100) of horizontal tube falling film evaporator type, said heat exchanger (1,100) comprising a shell (10,110), at least one bundle (20,120,140) of heat exchanger tubes (21,121,141) that is arranged within the shell (10,110), said heat exchanger tubes (21,121,141) having a tube length (Lt) defining a horizontal x-direction and said bundle (20, 120,140) of heat exchanger tubes (21,121,141) having a vertical extension (Htb,Htb1,Htb2) defining a z-direction that is orthogonal to said x-direction, and at least one refrigerant distribution layer (30,130,150) located above at least one bundle (20,120, 140) of heat exchanger tubes (21,121,141), said at least one refrigerant distribution layer (30,130,150) comprising perforated pipes (31,131,151) which have holes (133a.1,133a.2, 133a.3,133a.4,133a.5,133a.6,133a.7) for emitting refrigerant towards the bundle (20,120,140) of heat exchanger tubes (21, 121,141) above which said refrigerant distribution layer (30, 130,150) is located, wherein at least some of said perforated pipes (31,131,151) have a longitudinal axis defining a horizontal y-direction that is orthogonal to the x-direction defined by said heat exchanger tubes (21,121,141) and wherein perforations of the perforated pipes (31,131,151) having a longitudinal y-direction that is orthogonal to the x-direction defined by said heat exchanger tubes are formed by holes (133a.1,133a.2,133a.3,133a.4,25 133a.5,133a.6,133a.7) that are arranged in sets (133a,133b, 133c,133d), wherein each set (133a,133b,133c,133d) of holes is arranged on a circumference lying on a vertical xz-plane that passes through a heat exchanger tube (21,121, 141) of the bundle (20,120,140) and located above a respective heat exchanger30 tube (121a.1,121a.2,121b.1,121b.2,141a.1,141a.2,141b.1,141b.2) of said bundle (20,120,140) of heat exchanger tubes (21,121, 141)."
The patent application was internationally filed on Apr. 27, 2023, under International application No.PCT/EP2023/061172.
