Abstract

A combined heat exchanger and active grille shutter assembly. The assembly includes a rotatable shutter and an actuator configured to rotate the shutter. A conduit of the shutter is configured to accommodate flow of fluid therethrough and permit heat transfer between the fluid and air about the shutter. An inlet and an outlet are in fluid communication with the conduit.

First claim

What is claimed is:

1. A combined heat exchanger and active grille shutter assembly comprising:
a rotatable shutter;
an actuator configured to rotate the shutter;
a conduit of the shutter configured to accommodate flow of fluid therethrough and permit heat transfer between the fluid and air about the shutter;
an inlet in fluid communication with the conduit through which fluid enters the conduit; and
an outlet in fluid communication with the conduit through which fluid exits the conduit.

2. The assembly of claim 1 , wherein the rotatable shutter is one of a plurality of rotatable shutters movable from at least one open position in which a gap is defined between the plurality of rotatable shutters, and a closed position in which no gap is defined between the plurality of rotatable shutters; and
wherein the assembly includes at least one active grill shutter that is without the conduit.

3. The assembly of claim 1 , wherein the rotatable shutter includes a plurality of fins configured to facilitate heat transfer.

4. The assembly of claim 3 , wherein the fins are at an exterior of the rotatable shutter.

5. The assembly of claim 3 , wherein the fins extend outward from the rotatable shutter.

6. The assembly of claim 3 , wherein the fins are at an interior of the conduit.

7. The assembly of claim 1 , further comprising an inlet tank and an outlet tank;
wherein the inlet includes an inlet tube connecting the inlet tank to the rotatable shutter, and the outlet includes an outlet tube connecting the outlet tank to the rotatable shutter.

8. The assembly of claim 7 , wherein the actuator is further configured to rotate the inlet tank and the outlet tank with the rotatable shutter.

9. The assembly of claim 1 , wherein the conduit is a multi-passage conduit.

10. The assembly of claim 1 , wherein the inlet is a first inlet and the outlet is a first outlet of the conduit, which is a first conduit;
wherein the assembly further includes a second inlet and a second outlet of a second conduit; and
wherein the first conduit and the second conduit are arranged to permit heat transfer between fluid flowing through the first conduit and fluid flowing through the second conduit.

11. The assembly of claim 1 , wherein the conduit is a first conduit of the rotatable shutter;
wherein the assembly further includes a second conduit that is opposite to the first conduit;
wherein the inlet is an inlet of the first conduit and the outlet is an outlet of the second conduit; and
wherein a tank is between, and connects, the first conduit and the second conduit.

12. The assembly of claim 1 , wherein the conduit is defined by an extruded tube.

13. The assembly of claim 1 , wherein the conduit is defined by a brazed tube.

14. The assembly of claim 13 , wherein the brazed tube includes wings that overlap with wings of neighboring rotatable shutters to restrict airflow past the assembly.

15. The assembly of claim 1 , wherein the fluid is one of air, refrigerant, coolant, water, oil, transmission oil, engine oil, and power steering oil.

16. A combined heat exchanger and active grille shutter assembly for a vehicle comprising:
a plurality of shutters each rotatable to at least one open position in which a gap is defined between neighboring ones of the plurality of shutters, and a closed position in which no gap is defined between neighboring ones of the plurality of shutters to restrict airflow across the assembly;
an actuator configured to rotate the plurality of rotatable shutters;
each one of the plurality of shutters defining a conduit configured to accommodate flow of fluid therethrough and permit heat transfer between the fluid and air about the plurality of shutters;
an inlet tank in fluid communication with the conduit; and
an outlet tank in fluid communication with the conduit.

17. The assembly of claim 16 , wherein the actuator is configured to rotate the inlet tank and the outlet tank, or individual shutters.

18. The assembly of claim 16 , wherein the plurality of shutters include a plurality of heat dissipating fins at at least one of an interior and exterior of the plurality of shutters.

19. The assembly of claim 16 , wherein each one of the plurality of shutters includes wings that overlap with one another when the plurality of shutters are closed to restrict airflow past the assembly.

20. The assembly of claim 16 , wherein the conduit of each one of the plurality of shutters is defined by a brazed tube including wings that overlap with wings of neighboring rotatable shutters to restrict airflow past the assembly.
