Abstract

In one aspect, a heat exchanger layer for an adsorption bed heat exchanger assembly is provided. The heat exchanger layer includes at least one fluid tube configured to supply a heat transfer fluid, a sorbent containment structure having a plurality of compartments, and a sorbent disposed within the plurality of compartments.

First claim

The invention claimed is:

1. A heat exchanger layer for an adsorption bed heat exchanger assembly, the heat exchanger layer comprising:
at least one fluid tube configured to supply a heat transfer fluid;
a first sorbent containment structure having a plurality of compartments;
a second sorbent containment structure having a plurality of compartments;
a sorbent disposed within the plurality of compartments;
a first fine screen and a second fine screen disposed adjacent the plurality of compartments and a first coarse screen and a second coarse screen disposed adjacent the first and second fine screens, respectively;
wherein the first coarse screen, the first fine screen, the first sorbent containment structure, the at least one fluid tube, the second sorbent containment structure, the second fine screen and the second coarse screen are arranged in sequence in a stacked relationship.

2. The heat exchanger layer of claim 1 , wherein the at least one fluid tube is a plurality of tubes fluidly coupled between the first and second headers, and wherein a plurality of fins coupled between adjacent tubes of the plurality of tubes, wherein the plurality of fins and the plurality of tubes define sorbent containment structure having the plurality of compartments.

3. The heat exchanger layer of claim 2 , further comprising: a first header disposed at a first end; and
a second header disposed at a second end, the plurality of tubes fluidly coupled between the first and second headers.

4. The heat exchanger layer of claim 2 , wherein the plurality of tubes comprises a plurality of flat tubes.

5. The heat exchanger layer of claim 4 , wherein each flat tube of the plurality of flat tubes has a substantially rectangular cross-section.

6. The heat exchanger layer of claim 4 , wherein at least one flat tube of the plurality of flat tubes comprises a plurality of ports extending therethrough configured to receive a refrigerant.

7. The heat exchanger layer of claim 1 , wherein the sorbent containment structure is a first honeycomb layer and a second honeycomb layer disposed on either side of the at least one fluid tube.

8. An adsorption bed heat exchanger assembly comprising:
a pressure vessel; and
a plurality of heat exchanger layers disposed within the pressure vessel, wherein each heat exchanger layer of the plurality of heat exchanger layers comprises:
at least one fluid tube configured to supply a heat transfer fluid;
a first sorbent containment structure having a plurality of compartments;
a second sorbent containment structure having a plurality of compartments;
a sorbent disposed within the plurality of compartments;
a first fine screen and a second fine screen disposed adjacent the plurality of compartments and a first coarse screen and a second coarse screen disposed adjacent the first and second fine screens, respectively;
wherein the first coarse screen, the first fine screen, the first sorbent containment structure, the at least one fluid tube, the second sorbent containment structure, the second fine screen and the second coarse screen are arranged in sequence in a stacked relationship.

9. The assembly of claim 8 , wherein each heat exchanger layer of the plurality of heat exchanger layers is rectangular.

10. The assembly of claim 8 , wherein the plurality of tubes comprises a plurality of flat tubes.

11. The assembly of claim 10 , wherein each flat tube of the plurality of flat tubes has a substantially rectangular cross-section.

12. The assembly of claim 10 , wherein at least one flat tube of the plurality of flat tubes comprises a plurality of ports extending therethrough configured to receive a refrigerant.

13. The assembly of claim 8 , wherein the at least one fluid tube is a plurality of tubes fluidly coupled between the first and second headers, and wherein a plurality of fins coupled between adjacent tubes of the plurality of tubes, wherein the plurality of fins and the plurality of tubes define sorbent containment structure having the plurality of compartments.

14. The assembly of claim 8 , wherein the sorbent containment structure is a first honeycomb layer and a second honeycomb layer disposed on either side of the at least one fluid tube.
