Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2024/071222
Kind Code:
A1
Abstract:
This heat exchanger is provided with a core portion with which it is possible to exchange heat between a plurality of types of fluid. The core portion includes a core outer peripheral wall constituting an outer peripheral surface, and one or a plurality of unit structures disposed inside the outer circumferential wall. The unit structures each comprise a plurality of flow passages formed to extend in a prescribed direction as a whole, and separating walls dividing the plurality of flow passages. The plurality of flow passages include a first flow passage through which a first fluid is caused to flow, and a second flow passage through which a second fluid that exchanges heat with the first fluid via the separating wall is caused to flow. The separating walls include a partition wall portion. The partition wall portion has a shape that is twisted so as to rotate, in accordance with a position in the prescribed direction, about a central axis of rotation that extends in the prescribed direction, and is formed so as to extend in a spiral shape from the central axis of rotation in a cross section perpendicular to the prescribed direction.
