Abstract

A collapsible heat exchanger comprising a first sheet; a second sheet on an opposing side of the collapsible heat exchanger from the first sheet; a first expansion element coupled to and extending between the first and second sheets; a second expansion element coupled to and extending between the first and second sheets; a manifold including a plurality of channels defined by at least one of a plurality of internal sidewalls; and a heat exchanger cavity defined at least by the plurality of channels and a first and second fluid conduit.

First claim

What is claimed is:

1. A method of operating a portable collapsible air conditioner, the method comprising:
transporting the portable collapsible air conditioner in a collapsed configuration from a first location to a second location that is remote from the first location, the portable collapsible air conditioner comprising:
a first sheet;
a second sheet on an opposing side of the collapsible air conditioner from the first sheet, the first sheet disposed parallel to the second sheet and to an axis X;
a first bellows coupled to and extending between the first and second sheets and perpendicularly to the first and second sheets at a first end of the first and second sheets;
a second bellows coupled to and extending between the first and second sheets and perpendicularly to the first and second sheets at a second end of the first and second sheets;
a manifold disposed between the first and second bellows and the first and second sheets, the manifold including:
a plurality of channels extending along the axis X, the plurality of channels defined by at least one of a plurality of internal sidewalls,
a first channel of the plurality of channels defined at least in part by the first sheet, and
a second channel of the plurality of channels defined at least in part by the second sheet,

a plurality of internal passages defined by the internal sidewalls, the passages extending through the collapsible air conditioner to opposing sides of the collapsible air conditioner along an axis Y that is perpendicular axis X and to axis Z, the plurality of internal passages in a closed configuration with the internal sidewalls touching when the collapsible air conditioner is in the collapsed configuration, and the plurality of internal passages in an open configuration with the internal sidewalls spaced apart when the collapsible air conditioner is in an expanded configuration;
a first fluid conduit disposed on a first side of the manifold;
a second fluid conduit disposed on a second side of the manifold opposing the first side;
a first fluid port communicating with the first fluid conduit;
a second fluid port communicating with the second fluid conduit; and
a heat exchanger cavity defined at least by the plurality of channels and the first and second fluid conduit;

introducing a first fluid into the heat exchanger cavity at the second location to expand the collapsible air conditioner from the collapsed configuration to the expanded configuration;
causing heat exchange between the first fluid and a second fluid surrounding the collapsible air conditioner, including within the plurality of internal passages, while the collapsible air conditioner is in the expanded configuration at the second location;
removing the first fluid from the heat exchanger cavity at the second location to collapse the collapsible air conditioner from the expanded configuration to the collapsed configuration; and
transporting the collapsible air conditioner while in the collapsed configuration from the second location to a third location that is remote from the first and second locations.

2. The method of operating a portable collapsible air conditioner of claim 1 , wherein introducing the first fluid into the heat exchanger cavity at the second location to expand the collapsible air conditioner from the collapsed configuration to the expanded configuration comprises: introducing the first fluid into the first fluid port so that the first fluid travels into the first conduit, then travels into the plurality of channels of the manifold to the second conduit and then leaves the heat exchanger cavity via the second port.

3. The method of operating a portable collapsible air conditioner of claim 1 , wherein the first fluid is a liquid and wherein the second fluid is air.

4. The method of operating a portable collapsible air conditioner of claim 1 , wherein the portable collapsible air conditioner is part of a portable refrigeration bag or portable freezer bag.

5. A method of operating a collapsible heat exchanger, the method comprising:
introducing a first fluid into the collapsible heat exchanger to change the collapsible heat exchanger from a collapsed configuration to an expanded configuration, the collapsible heat exchanger comprising:
a first sheet;
a second sheet on an opposing side of the collapsible heat exchanger from the first sheet,
a first bellows coupled to and extending between the first and second sheets at a first end of the first and second sheets;
a second bellows coupled to and extending between the first and second sheets at a second end of the first and second sheets;
a manifold disposed between the first and second bellows and the first and second sheets, the manifold including:
a plurality of channels defined by at least one of a plurality of internal sidewalls,
a first channel of the plurality of channels defined at least in part by the first sheet, and
a second channel of the plurality of channels defined at least in part by the second sheet,

a plurality of internal passages defined by the internal sidewalls, the passages extending through the collapsible heat exchanger, the plurality of internal passages in a closed configuration with the internal sidewalls touching when the collapsible heat exchanger is in the collapsed configuration, and the plurality of internal passages in an open configuration with the internal sidewalls spaced apart when the collapsible heat exchanger is in the expanded configuration;
a first fluid conduit disposed on a first side of the manifold;
a second fluid conduit disposed on the second side of the manifold opposing the first side;
a first fluid port communicating with the first fluid conduit;
a second fluid port communicating with the second fluid conduit; and
a heat exchanger cavity defined at least by the plurality of channels and the first and second fluid conduit; and

causing heat exchange between the first fluid and a second fluid surrounding the collapsible heat exchanger, including within the plurality of internal passages, while the collapsible heat exchanger is in the expanded configuration.

6. The method of operating a collapsible heat exchanger of claim 5 , wherein the first sheet is disposed parallel to the second sheet.

7. The method of operating a collapsible heat exchanger of claim 5 , wherein the bellows extend perpendicularly to the first and second sheets at a respective first end and second end of the first and second sheets.

8. The method of operating a collapsible heat exchanger of claim 5 , wherein the plurality of channels extend in parallel to each other.

9. The method of operating a collapsible heat exchanger of claim 5 , wherein introducing the first fluid into the heat exchanger cavity to expand the collapsible heat exchanger from the collapsed configuration to the expanded configuration comprises:
introducing the first fluid into the first fluid port so that the first fluid travels into the first conduit, then travels into the plurality of channels of the manifold to the second conduit and then leaves the heat exchanger cavity via the second port.

10. A method of operating a collapsible heat exchanger, the method comprising:
introducing a first fluid into the collapsible heat exchanger to change the collapsible heat exchanger from a collapsed configuration to an expanded configuration, the collapsible heat exchanger comprising:
a first sheet;
a second sheet on an opposing side of the collapsible heat exchanger from the first sheet;
a first expansion element coupled to and extending between the first and second sheets;
a second expansion element coupled to and extending between the first and second sheets;
a manifold including a plura
