Abstract
Official abstract text for this publication.
An exhaust gas heat recovery device includes an inner cylinder, a first fluid passage that is formed in the inner cylinder and in which first fluid flows, an outer cylinder that is formed by at least two divided bodies to surround the inner cylinder, and a second fluid passage that is formed between the inner cylinder and the cuter cylinder and in which second fluid flows.
First claim
Opening claim text (preview).
1 - 8 . (canceled) 9 . An exhaust gas heat recovery device comprising: an inner cylinder; a first fluid passage that is formed in the inner cylinder and in which first fluid flows; an outer cylinder that is formed by at least two divided bodies to surround the inner cylinder; and a second fluid passage that is formed between the inner cylinder and the outer cylinder and in which second fluid flows, wherein each of the at least two divided bodies has a butted portion at a joining portion with a remaining adjacency of the at least two divided bodies, and a pair of pipes for flowing the second fluid into and out-from the second fluid passage is formed at the butted portions of the at least two divided bodies. 10 . The exhaust gas heat recovery device according to claim 9 , further comprising: a heat recovery member that accumulates heats and is disposed at a position in the inner cylinder and on an inner side of the second fluid passage. 11 . A manufacturing method of an exhaust gas heat recovery device, wherein the exhaust gas heat recovery device comprises an inner cylinder, a first fluid passage that is formed in the inner cylinder and in which first fluid flows, an outer cylinder that is formed by at least two divided bodies to surround the inner cylinder, and a second fluid passage that is formed between the inner cylinder and the outer cylinder and in which second fluid flows, the method comprising: forming the at least two divided bodies; forming the outer cylinder by joining the at least two divided bodies at butted portions of the at least two divided bodies; and attaching the outer cylinder onto the inner cylinder to form the second fluid passage between the inner cylinder and the outer cylinder. 12 . The manufacturing method of an exhaust gas heat recovery device according to claim 11 , wherein each of the at least two divided bodies is formed by press working. 13 . The manufacturing method of an exhaust gas heat recovery device according to claim 11 , further comprising: attaching a heat recovery member that accumulates heats at a position in the inner cylinder and on an inner side from the second fluid passage.
