Spiral heat exchanger with power through the central tube

摘要

Heat exchanger with: - a jacket that extends along a longitudinal axis (L) and that surrounds a housing (M) of the heat exchanger (1), - a bundle of tubes (R) arranged in the housing (M) with a plurality of tubes (70) helically wound around a central tube (10) extending along the longitudinal axis (L) and - at least one predistribution tank (50) disposed in the housing (M) for the reception and degassing of a mixture of liquid and gas (F ') designed for the contribution of degassed liquid (F) in at least one predistribution tank (50) to a distribution device (60), configuring the distribution device (60) so that the liquid (F) is applied to the tube bundle (R), characterized in that the jacket (20) has an inlet (30) at the top (2) of the heat exchanger (1) ) aligned with the longitudinal axis (L), especially in the form of an inlet tube (30), which has one with exion of flow with the central tube (10), and because the central tube (10) has at least one hole (100) that flows into at least one predistribution tank (50) so that the mixture of liquid and gas ( F ') can be introduced into the predistribution tank (50), which is provided with at least one, through the inlet (30), the central tube (10) and the side hole (100), at least one, of the central tube (10).
