    • The cylindrical enclosure 12 of a recuperator 10 as in FIG. 2 contains an annular coaxial heat exchanger 50 full of cooling liquid 22 circulating therethrough. Exhaust gas from an internal combustion engine flows from an inlet end 32 through the heat exchanger 50, first in an axial region 15 via a conduit 14, then back through a surrounding annular region 18, then through tubes 37 to an outlet end 34. The inlet 30 and outlet 31 for the gas are in the side wall 40 of the cylindrical body 12, and the exhaust gas 11 enters and leaves via conduits 14 and 19 that are perpendicular to the side wall 40 at the inlet 30 and at the outlet 31. So the ends 41 and 42 of the body 12 are free of adjacent obstruction, and at least one of them is removable, as in FIG. 4 or FIG. 5 . Thus, the recuperator 10 can be opened and closed to make the interior accessible for inspection, cleaning, or other desired purpose.
    • 如图1所示的换热器10的圆柱形外壳12。 图2包含一个环形同轴热交换器50,其中充满了通过其循环的冷却液22。 来自内燃机的废气从入口端32流经热交换器50,首先经由管道14在轴向区域15中流动,然后通过周围的环形区域18,然后通过管37到出口端34。 用于气体的入口30和出口31位于圆柱体12的侧壁40中,并且废气11通过导管14和19进入并离开,导管14和19在入口30处和出口31处垂直于侧壁40 因此,主体12的端部41和42没有相邻的障碍物,并且它们中的至少一个是可移除的,如图1所示。 图4或图4。 5。 因此,可以打开和关闭换热器10以使得内部可以进行检查,清洁或其它期望的目的。
