Abstract
A heat exchanger includes at least two tube sections wound helically to form a spiral and are arranged in an interlacing manner inside one another for guiding a heat transfer fluid. The heat exchanger includes a first tube section helically wound to form a first spiral. The first tube section is for guiding a first heat transfer fluid and a second tube section is helically wound to form a second spiral, the first spiral and the second spiral being arranged in an interlacing manner inside one another and being connected to one another.

1-11. (canceled)
A heat exchanger comprising:
- a first tube section helically wound to form a first spiral, the first tube section for guiding a first heat transfer fluid;
- and
- a second tube section helically wound to form a second spiral, the first spiral and the second spiral being arranged in an interlacing manner inside one another and being connected to one another.
A method for the production of a heat exchanger, the method comprising:
- winding a tube around a first winding core to thereby form a first spiral;
- placing a slotted second winding core around the first spiral;
- and
- from the tube, winding a second spiral on the second winding core in a manner resulting in the second spiral surrounding the first spiral.
