Heat exchanger for indirect heat exchange between two mediums, has multiple pipes wound around core pipe such that two sections of pipe bundles are formed, where former and latter sections circulate core pipe separately

摘要

The heat exchanger has multiple pipes that form pipe bundles (10) for receiving a medium, where the pipes are wound around a core pipe such that two sections (11,12) of the pipe bundles are formed. The former section circulates the core pipe, where the latter section circulates the core pipe separately. The latter section surrounds the former section. The both sections have assigned inlet (E,E') such that the both sections are separated with the former medium.
