Abstract
A heat exchanger includes: an inner tube through which a heat medium is allowed to flow; an outer tube through which the inner tube is to be inserted, the outer tube including an inner peripheral surface that faces an outer peripheral surface of the inner tube through intermediation of a gap, and allowing vapor to flow through a region between the outer peripheral surface and the inner peripheral surface; and a flow path wall portion stretching from the outer peripheral surface to the inner peripheral surface. The flow path wall portion stretches along an extending direction of the inner tube or the outer tube while extending spirally between the outer peripheral surface and the inner peripheral surface.
Claims6
A heat exchanger, comprising:
- at least one heat exchange unit, configured to transfer heat between a first heat medium and a second heat medium,
- wherein the heat exchange unit includes:
- a first tube, through which the first heat medium is allowed to flow;
- a second tube, through which the first tube is to be inserted, the second tube including a second inner peripheral surface that faces a first outer peripheral surface of the first tube through intermediation of a gap, and allowing the second heat medium to flow through a region between the first outer peripheral surface and the second inner peripheral surface;
- and
- a flow path wall portion, stretching from the first outer peripheral surface to the second inner peripheral surface,
- wherein the flow path wall portion stretches along an extending direction of the first tube or the second tube while extending spirally between the first outer peripheral surface and the second inner peripheral surface.
