Abstract

The invention relates to a heat exchanger (1) having a tube bundle (10) with a large number of tubes wound around a central pipe (100), a shell (20) enclosing the tube bundle (10) and defining a shell space (200) surrounding the tube bundle (10), and a liquid distributor (30) having distributor arms (300) for distributing a liquid (F) into the shell space (200) and onto the tube bundle (10), and drain pipes (340) for supplying the distributor arms with liquid (F). The distributor arms (300) are connected in a flow-guiding manner to a ring channel (400) positioned along the periphery of the shell (20). For degassing liquid (F), central pipe (100) is connected in a flow-guiding manner to the distributor arms (300).
