CONTROLLED LIQUID DISTRIBUTOR OF COIL TUBULAR HEAT EXCHANGER FOR IMPLEMENTATION OF VARIOUS LIQUID LOADS Russian patent published in 2023 - IPC F28D7/02 F28F27/02 F28F9/02 

FIELD: heat exchangers.

SUBSTANCE: invention relates to a heat exchanger (1) comprising: a drawer (2) surrounding the inner space (3) of the heat exchanger (1), the inner space (3) being configured to receive the first fluid (M); an inner pipe (4) extending in the inner space (3); a tube bundle (5) containing several tubes (50) wound around the inner tube (4), wherein the tube bundle (5) is configured to receive at least one second fluid (M') with the possibility of indirect heat transfer between the first medium (M) and at least one second medium (M'), and a liquid distributor (6) located above the tube bundle (5) in the inner space (3) for supplying the liquid phase (F) of the first medium (M) to the tube bundle (5), wherein the liquid distributor (6) comprises distribution elements (60) protruding in the radial direction (R) from the inner tube (3); an annular channel (61) passing over the distribution elements (60) in the direction along the circumference (U) of the shell (2), and a collection tank (62) formed by an inner pipe (4), each of the annular channel (61) and the collection tank (62) is configured to collect the first medium (M). In accordance with the invention, the distribution elements (60) for supplying the liquid phase (F) of the first medium (M) to the tube bundle (5) form at least one first container (60a) and at least one second container (60b), separated from the first container (60a).

EFFECT: effective performance.
