Abstract

A method of making and operating a heat exchanger that includes introducing a first fluid into a fluid chamber of a membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a non-flat configuration while the membrane heat exchanger is disposed within a chamber with the membrane heat exchanger extending from a first end to a second end of the chamber and generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber. The membrane heat exchanger includes sheets that form a fluid chamber.

First claim

What is claimed is:

1. A method of making and operating a heat exchanger, the method comprising:
introducing a first fluid into a fluid chamber of a membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a non-flat configuration while the membrane heat exchanger is disposed within a chamber with the membrane heat exchanger extending from a first end to a second end of the chamber, the membrane heat exchanger comprising a first and second sheet that form at least one fluid chamber defined by the first and second sheet and a first and second end that respectively communicate with a first and second port defined by at least one of the first and second sheet, the first end of the membrane heat exchanger disposed at the first end of the chamber and the second end of the membrane heat exchanger disposed at the second end of the chamber, wherein the non-flat configuration includes one or more of a spiral or helical configuration; and
generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between the first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber.

2. The method of claim 1 , wherein the first fluid within the fluid chamber of the membrane heat exchanger is a liquid and the second fluid within the duct chamber is a gas.

3. The method of claim 1 , wherein the first temperature is lower than the second temperature and the heat exchange between the first and second fluid results in cooling of the second fluid within the duct chamber.

4. A method of making and operating a heat exchanger, the method comprising:
inserting an elongated membrane heat exchanger into a chamber at a first end so that the elongated membrane heat exchanger extends from the first end to a second end of the chamber, the elongated membrane heat exchanger comprising a first and second sheet that form at least one fluid chamber defined by the first and second sheet and a first and second end that respectively communicate with a first and second port defined by at least one of the first and second sheet, the first end of the membrane heat exchanger disposed at the first end of the chamber and the second end of the membrane heat exchanger disposed at the second end of the chamber;
introducing a first fluid into the fluid chamber of the membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a spiral configuration while the membrane heat exchanger is disposed within the chamber; and
generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between the first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber.

5. The method of claim 4 , wherein the chamber is defined by one or more of a duct, pipe and tube.

6. The method of claim 4 , wherein the chamber defines a plurality of one or more of bends, convolutions, curves, spirals, changes in size and changes in shape.

7. The method of claim 4 , wherein the chamber is long and winding.

8. The method of claim 4 , wherein the chamber is defined by one or more of an HVAC system, a vehicle exhaust system, a vehicle cooling system, a liquid supply line, and a liquid dump line.

9. The method of claim 4 , wherein the fluid flow includes the first fluid entering the fluid chamber of the membrane heat exchanger at the first end of the membrane heat exchanger having a first temperature and the first fluid leaving the fluid chamber of the membrane heat exchanger at the second end of the membrane heat exchanger having a second temperature that is different from the first temperature.

10. The method of claim 9 , wherein the first temperature is lower than the second temperature and the heat exchange between the first and second fluid results in cooling of the second fluid within the chamber.

11. The method of claim 4 , wherein the membrane heat exchanger is configured to have the flat configuration when fluid is not present within the fluid chamber and configured to have the spiral configuration when fluid is present within the fluid chamber.

12. The method of claim 4 , wherein the membrane heat exchanger has symmetry about a central axis X.

13. The method of claim 4 , wherein the first fluid within the fluid chamber of the membrane heat exchanger is a liquid and the second fluid within the chamber is a gas.

14. A method of making and operating a heat exchanger, the method comprising:
introducing a first fluid into a fluid chamber of a membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a non-flat configuration while the membrane heat exchanger is disposed within a chamber with the membrane heat exchanger extending from a first end to a second end of the chamber, the membrane heat exchanger comprising a first and second sheet that form at least one fluid chamber defined by the first and second sheet and a first and second end that respectively communicate with a first and second port defined by at least one of the first and second sheet, the first end of the membrane heat exchanger disposed at the first end of the chamber and the second end of the membrane heat exchanger disposed at the second end of the chamber; and
generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between the first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber.

15. The method of claim 14 , wherein the chamber is defined by one or more of a duct, pipe and tube.

16. The method of claim 14 , wherein the chamber defines a plurality of one or more of bends, convolutions, curves, spirals, changes in size and changes in shape.

17. The method of claim 14 , wherein the chamber is long and winding.

18. The method of claim 14 , wherein the first end and the second end of the chamber are terminal ends of the chamber.

19. The method of claim 14 , wherein the chamber is defined by one or more of an HVAC system, a vehicle exhaust system, a vehicle cooling system, a liquid supply line, and a liquid dump line.
