Abstract:
A heat transfer system for transferring heat for use onboard a vehicle, the heat transfer system comprisingexhaust conductor means for conducting exhaust gas discharged from an engine in series along a serpentine path through an annular outer exhaust gas passageway in a first direction, an annular intermediate exhaust gas passageway in a second direction opposite to the first direction, and an inner exhaust gas passageway in the first direction to generate back pressure for transmission to the engine discharging exhaust gas to the annular outer exhaust gas passageway so that heat of exhaust gas discharged into the annular outer exhaust gas passageway is maximized, and fluid conductor means for conducting a fluid through the outer exhaust gas passageway to heat the fluid using heat from the exhaust gas and providing the heated fluid for use onboard a vehicle.
