Abstract

A coolant control valve (CCV) includes an outer housing, an actuator, a valve body, and one or more thermoelectric generators (TEGs). The outer housing includes at least one inlet and at least one outlet. The TEG is operatively connected to the actuator and can be a lone source of power to the CCV or assist a primary power source. The CCV can utilize a power management device that can receive power input from either the TEG or the primary power source. The TEG has a first surface and a second surface, either of which can be exposed to air or a cooling system fluid or coolant; the coolant can be water, ethylene glycol, a combination thereof, or any other fluid that is utilized in a system that provides temperature management for a component or system.

First claim

What we claim is:

1. A coolant control valve comprising:
an actuator;
a valve body actuated by the actuator;
an outer housing having:
at least one inlet; and,
at least one outlet; and,

at least one thermoelectric generator formed within a wall of the coolant control valve, the at least one thermoelectric generator having:
a first surface in contact with a first medium; and,
a second surface in contact with a second medium; and,

the at least one thermoelectric generator operatively connected to the actuator.

2. The coolant control valve of claim 1 , wherein the at least one thermoelectric generator generates power to solely power the actuator to actuate the valve body.

3. The coolant control valve of claim 1 , wherein at least one of a primary power source and the at least one thermoelectric generator provide power to the actuator.

4. The coolant control valve of claim 1 , further comprising a power management device that receives power input from at least one of a primary power source and the at least one thermoelectric generator.

5. The coolant control valve of claim 4 , wherein in a first power state, the power input from the at least one thermoelectric generator exceeds the power input from the primary power source.

6. The coolant control valve of claim 4 , wherein in a second power state, the power input from the primary power source exceeds the power input from the at least one thermoelectric generator.

7. The coolant control valve of claim 1 , wherein the at least one thermoelectric generator is overmolded within the outer housing.

8. The coolant control valve of claim 1 , wherein the outer housing further comprises at least one end cover.

9. The coolant control valve of claim 8 , wherein the at least one thermoelectric generator is arranged within the at least one end cover.

10. The coolant control valve of claim 1 , wherein the at least one thermoelectric generator is arranged within an outer wall of the outer housing.

11. The coolant control valve of claim 1 , wherein the at least one thermoelectric generator is arranged within an inner wall of the outer housing.

12. The coolant control valve of claim 1 , wherein the first medium comprises air and the second medium comprises cooling system fluid.

13. The coolant control valve of claim 1 , wherein the first medium comprises cooling system fluid and the second medium comprises cooling system fluid.

14. The coolant control valve of claim 1 , wherein the valve body is rotationally actuated by the actuator.

15. The coolant control valve of claim 1 , wherein the valve body is linearly actuated by the actuator.

16. The coolant control valve of claim 1 , wherein the valve body is configured with at least one fluid opening.

17. A coolant control valve comprising:
an actuator;
a valve body engaged with the actuator;
an outer housing having:
at least one inlet; and,
at least one outlet; and,

at least one thermoelectric generator formed within a wall of the coolant control valve, the at least one thermoelectric generator having:
a first surface in contact with a first medium; and,
a second surface in contact with a second medium.

18. The coolant control valve of claim 17 , wherein the at least one thermoelectric generator is formed in the outer housing.

19. The coolant control valve of claim 17 , wherein the coolant control valve is configured to receive an electronic signal to move the valve body to a desired position.

20. A coolant control valve comprising:
an actuator integrated within the coolant control valve;
a valve body actuated by the actuator;
an outer housing having:
at least one inlet; and,
at least one outlet; and,

at least one thermoelectric generator formed within a wall of the coolant control valve, the at least one thermoelectric generator having:
a first surface in contact with a first medium; and,
a second surface in contact with a second medium.
