2. In combination:
-
a heat exchanger comprising; a fluid impervious unitary tubular body having a first end, a second end, and fluid impervious sidewalls formed out of a single length of conduit wound in a spiral coil; and means for coupling with an exhaust pipe positioned at each of the first end and the second end of the tubular body; an hydrocarbon fuelled engine of a vehicle; a series of axially aligned exhaust pipes connected to the engine, the tubular body being connected to the exhaust pipes, such that exhaust gases from the engine pass through the tubular body; an hydraulic system; and a closed loop fluid circulation conduit connecting the hydraulic system to the coil, such that hydraulic fluids used are circulated through the coil and back to the hydraulic system. - View Dependent Claims (3)
