Patent ID: 7490662

Claim:
A heat exchanger for a vehicle, the heat exchanger comprising: an inlet and an outlet port for receiving a fluid flow; a manifold in fluid communication with the inlet port; a plurality of cooling tubes in fluid communication with the manifold; a thermal bypass valve located in the manifold and including a valve body and a sleeve, the sleeve being separately formed from the manifold, the inlet port has a wall extending into the sleeve, the valve body being moveable between first and second positions, the valve body being configured in the first position to divert at least a portion of the fluid flow from the inlet port to the outlet port through the sleeve without passing the at least a portion of the fluid flow through the cooling tubes, and in the second position the valve body being moved in a direction generally perpendicular to the cooling tubes such that a surface of the valve body cooperates with the sleeve to restrict flow through the sleeve between the inlet and outlet ports and the fluid flow is directed from the inlet port to the outlet port through the cooling tubes.
