Abstract

An oil cooler comprises a cooler core having an oil fin. The oil fin includes a moveable window. The moveable window includes a base and a first flap on one side of the base. The first flap moves between a closed position and an open position. The first flap is in the open position when the cooler core is in a hot condition.

First claim

I claim:

1. An oil cooler, comprising:
a cooler core having an oil fin;
wherein the oil fin includes a fin element;
wherein the fin element includes a moveable window that provides an opening from one side of the fin element through and to an opposite side of the fin element;
wherein the moveable window includes a window base that divides the opening, a first flap attached on one side of the window base, and a second flap attached on an opposite side of the window base;
wherein the first and second flaps move between a closed position and an open position;
wherein, when the first and second flaps move to the open position, the first and second flaps move towards one another.

2. The cooler of claim 1 , wherein the fin is in a serpentine configuration.

3. The cooler of claim 1 , wherein the fin element includes an element base, a first leg, and a second leg.

4. The cooler of claim 1 , wherein the fin is made of a bi-material.

5. The cooler of claim 1 , wherein the fin has a first coefficient of thermal expansion and a second coefficient of thermal expansion.

6. The cooler of claim 5 , wherein the first coefficient of thermal expansion is on one side of the fin and the second coefficient of thermal expansion in on another side of the fin.

7. The cooler of claim 1 , wherein the fin provides an oil flow path, and wherein the first flap extends into the oil flow path when the first flap is in the open position.
