Zusammenfassung: | To provide an exhaust gas cooling device capable of easily cooling exhaust gas from the center of an exhaust passage.SOLUTION: The exhaust gas cooling device for cooling exhaust gas passing through the exhaust passage includes a turbulence generation member having a bar-like part extending from the inner wall of the exhaust passage to the center of the exhaust passage for generating a turbulence flow with the exhaust gas hitting the bar-like part. For example, the turbulence generation member has the plurality of bar-like parts arranged side by side in the direction crossing the exhaust passage, and the exhaust passage is constructed so that the exhaust gas flows to the center and outside air flows along the outer periphery of the center.SELECTED DRAWING: Figure 1
【課題】排気通路の中央部の排気を冷却し易くすることが可能な排気冷却装置を提供する。【解決手段】排気冷却装置は、排気通路を通る排気を冷却する排気冷却装置であって、排気通路の内壁から排気通路の中心部へ延在する棒状部を有し、棒状部に排気が当たることで乱流を発生させる乱流発生部材を備える。例えば、乱流発生部材は、排気通路を横断する方向へ並ぶように配置された複数の棒状部を有する。また、排気通路は、中心部に排気が流れるように、かつ、中心部の外周部に外気が流れるように構成される。【選択図】図1 |
