Abstract
A heat exchanger apparatus having a first fluid channel, a second fluid channel, a bypass channel, and inlet and outlet manifolds. A thermal bypass valve assembly is positioned within the inlet manifold, and contains an outer sleeve having a first, second and third apertures axially displaced. An inner sleeve positioned within the outer sleeve and moveable from a first to a second position upon actuation of a first actuator. The inner sleeve has a first orifice on a wall of the inner sleeve and a second orifice defined by the inner sleeve second end. The first orifice aligns with the first aperture in the first position and the second aperture in the in the second position. A second actuator coupled to a stopper that engagingly disengages from the second orifice upon actuation of the second actuator.
