Abstract

A heat exchanger for indirectly transferring heat between a process medium and at least one first refrigerant, comprising: a shell which surrounds a shell space and extends along a longitudinal axis; and a pipe bundle which is disposed in the shell space and extends along the longitudinal axis of the shell from a lower end to an upper end of the pipe bundle in the shell space; wherein: the pipe bundle has a plurality of first pipes for receiving the first refrigerant; the first pipes are wound helically onto a core pipe of the heat exchanger. According to the invention, the first pipes each have an end which is formed by at least one nozzle via which the first refrigerant can be introduced into the shell space, the ends being disposed along the longitudinal axis of the shell at different heights.
