<P>PROBLEM TO BE SOLVED: To improve fuel economy, and to improve a heating effect in a vehicle room using cooling water by performing heat exchange between an exhaust gas in an internal combustion engine and the cooling water in the internal combustion engine, recovering the heat of the exhaust gas to the heat of the cooling water, and progressing the warm-up of the internal combustion engine. <P>SOLUTION: This exhaust gas heat recovery device includes an exhaust heat exchanger which performs efficient heat exchange by a simple structure by facilitating manufacture of the heat exchanger installed in the gas flowing direction of an exhaust gas passage in the exhaust gas passage in which a cooling water passage is formed of a pipe, and by progressing the heat exchange between the exhaust gas and a cooling water pipe by using a fixing member which supports and fixes the heat exchanger to the exhaust gas passage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
