Abstract

The invention relates to a heat exchanger system comprising a jacket extending along a longitudinal axis and surrounding a jacket space. A pipe bundle is arranged in the jacket space wherein pipes are wound helically around a central pipe. At least one pre-distributor container is arranged in the jacket space for accommodating and degassing a liquid-gas mixture and designed to coat a distributing means with liquid degassed in the at least one pre-distributor container. The distributing means is designed to deliver the liquid to the pipe bundle. At the top the jacket has an inlet which is aligned with the longitudinal axis and in fluid connection with the central pipe. The central pipe has at least one lateral opening so that the liquid-gas mixture can be fed via the inlet, the central pipe, and the at least one lateral opening into the at least one pre-distributor container.
