ABSTRACT:
An oil cooler for a motor vehicle includes a fluid inlet tank and a fluid outlet tank. A plurality of heat transfer tubes provides constant fluid communication between the inlet tank and the outlet tank. A bypass arrangement provides additional fluid communication between the fluid inlet tank and the fluid outlet tank under a first operating condition and the bypass arrangement precludes additional fluid communication between the inlet tank and the outlet tank under a second operating condition. The bypass arrangement may include a bypass tube and an element for selectively blocking the bypass tube. The element for selectively blocking the bypass tube may be automatically response to a change in oil temperature or a change in oil pressure.
