Abstract

A system for conditioning and moving a fluid can include a thermoelectric device comprising a first side and a second side, the first side configured to heat or cool the fluid with electrical current applied to the thermoelectric device. The system can include a fluid conduit configured to allow a fluid to flow therein and to transfer the fluid into being in thermal communication with the thermoelectric device. The system can include a flow control device in fluid communication with the thermoelectric device, the flow control device configured to direct the fluid in the fluid conduit with respect to the thermoelectric device. The system can include a flapper valve configured to move relative to the thermoelectric device to at least partially block flow of the fluid through a portion of the fluid conduit.

First claim

What is claimed is:

1. A method for conditioning and moving a fluid, the method comprising:
applying electrical current into a thermoelectric device;
heating or cooling the fluid with a first side of the thermoelectric device;
moving the fluid with a flow control device through a fluid conduit to flow the fluid into being in thermal communication with the thermoelectric device; and
moving a flapper valve relative to the thermoelectric device to block flow of the fluid through a portion of the fluid conduit.

2. The method of claim 1 , wherein the flapper valve is positioned in the fluid conduit outside of a perimeter in the fluid conduit, the perimeter defined in the fluid conduit by a surface area of the first side of the thermoelectric device in the fluid conduit.

3. A system for conditioning and moving a fluid, the system comprising:
a thermoelectric device comprising a first side and a second side, the first side configured to heat or cool the fluid with electrical current applied to the thermoelectric device;
a fluid conduit configured to allow the fluid to flow therein and to transfer the fluid into being in thermal communication with the thermoelectric device or away from being in thermal communication with the thermoelectric device, wherein the thermoelectric device is positioned in the fluid conduit;
a flow control device in fluid communication with the thermoelectric device, the flow control device configured to direct the fluid in the fluid conduit with respect to the thermoelectric device; and
a flapper valve configured to move relative to the thermoelectric device to block flow of the fluid through a portion of the fluid conduit,
wherein the flapper valve is positioned in the fluid conduit outside of a perimeter in the fluid conduit, the perimeter defined in the fluid conduit by a surface area of the first side or the second side of the thermoelectric device in the fluid conduit.

4. The system of claim 3 , wherein the flapper valve is positioned at an inlet portion of the fluid conduit.

5. The system of claim 3 , wherein the flapper valve is configured to move to permit flow of the fluid fully through the fluid conduit.

6. The system of claim 3 , wherein the flapper valve is configured to move to fully block flow of the fluid through the portion of the fluid conduit.

7. The system of claim 3 , wherein the flapper valve is configured to move to fully block flow of the fluid through an other portion of the fluid conduit, the other portion opposite the portion of the fluid conduit relative to flapper valve.

8. The system of claim 3 , wherein the flapper valve is configured to rotate relative to the thermoelectric device to at least partially block flow of the fluid through the portion of the fluid conduit.

9. The system of claim 3 , further comprising a control device configured to control the flapper valve based on a parameter of the fluid.

10. The system of claim 9 , wherein the parameter of the fluid comprises temperature of the fluid.

11. The system of claim 9 , further comprising a sensor configured to monitor the parameter of the fluid.

12. A system for conditioning and moving a fluid, the system comprising:
a thermoelectric device comprising a first side and a second side, the first side configured to heat or cool the fluid with electrical current applied to the thermoelectric device;
a fluid conduit configured to allow the fluid to flow therein and to transfer the fluid into being in thermal communication with the thermoelectric device or away from being in thermal communication with the thermoelectric device, wherein the thermoelectric device is positioned in the fluid conduit;
a flow control device in fluid communication with the thermoelectric device via the fluid conduit, the flow control device configured to move the fluid in the fluid conduit with respect to the thermoelectric device;
a divider wall separating the fluid conduit into a first fluid channel and a second fluid channel, the first fluid channel configured to direct the fluid to the first side of the thermoelectric device; and
a flapper valve connected to the divider wall, the flapper valve configured to rotate relative to the divider wall to block flow of the fluid through the first fluid channel or the second fluid channel,
wherein both the divider wall and the flapper valve are positioned outside of a perimeter in the fluid conduit, the perimeter defined in the fluid conduit by a surface area of the first side or the second side of the thermoelectric device in the fluid conduit.

13. The system of claim 12 , wherein the divider wall and the flapper valve are positioned at an inlet portion of the fluid conduit, and wherein the flapper valve is directly connected to the divider wall.

14. The system of claim 12 , wherein the flapper valve is proximate to the thermoelectric device relative to the divider wall.

15. The system of claim 12 , wherein the flapper valve is configured to rotate to permit flow of the fluid through both the first and second fluid channels.

16. The system of claim 12 , wherein the flapper valve is configured to rotate to fully block flow of the fluid through the first fluid channel.

17. The system of claim 12 , wherein the flapper valve is configured to rotate to fully block flow of the fluid through the second fluid channel.

18. The system of claim 12 , wherein the second fluid channel is configured to direct the fluid to the first side of the thermoelectric device.

19. The system of claim 12 , further comprising an other flow control device in fluid communication with the thermoelectric device via the fluid conduit, the other flow control device configured to move the fluid with respect to the thermoelectric device.

20. The system of claim 19 , wherein the flow control device is configured to direct the fluid through the first fluid channel, and wherein the other flow control device is configured to direct the fluid through the second fluid channel.

21. The system of claim 12 , further comprising a control device configured to control the flapper valve based on a parameter of the fluid.

22. The system of claim 21 , wherein the parameter of the fluid comprises temperature of the fluid.

23. The system of claim 21 , further comprising a sensor positioned in the fluid conduit configured to monitor the parameter of the fluid.
