Title:
EXHAUST HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2015/162897
Kind Code:
A1
Abstract:
 An exhaust heat exchanger is provided with fins (120) having a plurality of plates (221), said fins (120) being provided inside an exhaust channel (111) through which exhaust flows in the flow direction from the upstream side to the downstream side. The plurality of plates are provided so as to line up with the flow direction and the direction that is orthogonal to the flow direction. The plurality of plates adjacent to the flow direction are offset in a direction orthogonal to the flow direction. The plurality of plates have protruding parts (224) that protrude from the plurality of plates in the direction orthogonal to the flow direction. In the exhaust channel, when a direction orthogonal both to the flow direction and to the direction orthogonal to the flow direction is configured to be the direction of the fin height, the amount of protrusion pf the protruding parts for a second portion (B) positioned downstream from a first portion (A) of the protruding parts in the flow direction is greater than that of the first portion (A), and the protrusion amount of the protruding parts for a third portion (C) of the protruding parts is greater than that of a fourth portion (D) positioned farther away than the third portion (C) from the central portion of the protruding parts in the direction of the fin height.
