Abstract
An oil cooler and a radiator hose are combined in an all polymer structure. Generally concentric hoses provide two coolant paths with the wall of the inner hose providing heat transfer from one fluid to the other. The hoses are flexible or can be formed to conform to desired radiator hose routing. The hoses have deflectable vanes extending from their walls into the fluids to flex according to flow rate. The vanes induce turbulence to improve the thermal transfer especially at low flow rates but deflect at high flow rates to minimize pressure drop due to the vanes.
