HEAT RECOVERY SYSTEM

A tube stack 30 is created by stacking multiple flat tubes 32. Each flat tube 32 is formed to have upper and lower cutout areas 34 and 35 obtained by linearly cutting off an upper arc-shape and a lower arc-shape from a hollow, flat, and circular donut-shape. An emission inflow-side end plate 42 is a...

Zusammenfassung:	A tube stack 30 is created by stacking multiple flat tubes 32. Each flat tube 32 is formed to have upper and lower cutout areas 34 and 35 obtained by linearly cutting off an upper arc-shape and a lower arc-shape from a hollow, flat, and circular donut-shape. An emission inflow-side end plate 42 is attached to a casing 22, such that a cutout area 44 of the emission inflow-side end plate 42 is aligned with upper cutout areas 34 of the multiple flat tubes 32 to face upward. An emission outflow-side end plate 52 is attached to the casing 22, such that a cutout area 55 of the emission outflow-side end plate 52 is aligned with lower cutout areas 35 of the multiple flat tubes 32 to face downward. A shutoff valve 68 is provided on an emission inflow end of an emission flow conduit 60, which is arranged to pass through the center of the tube stack 30 and to have a heat insulating effect. During warm-up of an internal combustion engine, the shutoff valve 68 is closed to make an overall downward flow of the emission through intervals of the respective flat tubes 32. A flow of a heat exchange medium is, on the other hand, flowed overall upward within the respective flat tubes 32. Heat exchange is accordingly performed between the flow of the emission and the flow of the heat exchange medium for recovery of heat from the emission.
