Wound heat exchanger with a plurality of inlets and method for adjusting a heating surface of the heat exchanger

The invention relates to a heat exchanger (1), with a plurality of inlets (30-36), which are each connected to at least one assigned pipe (20) of the heat exchanger (1), such that at least one flow (S) of a first medium and a flow (S') of a second medium can each be introduced through at least...

Zusammenfassung:	The invention relates to a heat exchanger (1), with a plurality of inlets (30-36), which are each connected to at least one assigned pipe (20) of the heat exchanger (1), such that at least one flow (S) of a first medium and a flow (S') of a second medium can each be introduced through at least one assigned inlet (30, 32, 36, 33, 35) into the at least one assigned pipe (20). The heat exchanger (1) has a shell (10) which encloses a shell space (11) in which said pipes (20) are arranged, such that a flow (S'") of a medium guided in the shell space (11) particularly comes into an indirect heat exchange with a flow (S, S') of a medium guided in the pipe concerned (20), and wherein said pipes (20) are each wound around a core pipe (12) of the heat exchanger (1). According to the invention, each of the pipes (20) assigned to its inlet (30-36) defines a heating surface. The heat exchanger (1) has at least one switching means (100) designed to switch at least one of the inlets (30) back and forth between at least one first operating condition and a second operating condition, such that in the first operating condition the flow (S) of the first medium and in the second operating condition the flow (S') of the second medium can be introduced through the at least one inlet (30) into the at least one assigned pipe (20) in order to make more heating area available to the flow (S) of the first medium in the first operating condition and correspondingly less heating area available to the flow (S') of the second medium, and in the second operating condition to make more heating area available to the flow (S') of the second medium and correspondingly less heating area available to the flow (S) of the first medium.
