Abstract

A packed bed for a heat exchanger may comprise a frame and a first fin layer disposed within the frame. A second fin layer may be disposed within the frame. A first perforated sheet may be disposed between the first fin layer and the second fin layer. A sorbent material may be disposed within a volume of at least one of the first fin layer or the second fin layer.

First claim

What is claimed is:

1. A method of manufacturing a packed bed for a heat exchanger, comprising:
forming a first fin layer configured to fit within a frame, the first fin layer comprising first lanced offset fins;
forming a second fin layer configured to fit within the frame, the second fin layer comprising second lanced offset fins;
staggering the first lanced offset fins with the second lanced offset fins;
disposing a perforated sheet between the first fin layer and the second fin layer;
brazing the first fin layer to the perforated sheet and the second fin layer to the perforated sheet to form the packed bed;
disposing the packed bed within the frame; and
applying a sorbent material within the packed bed.

2. The method of claim 1 , further comprising sealing the packed bed within the frame.

3. The method of claim 1 , wherein the frame defines a fill port and wherein the applying the sorbent material further includes injecting the sorbent material into the frame through the fill port.

4. The method of claim 1 , further comprising stacking a plurality of packed beds with adjacent packed beds in thermal communication to form the heat exchanger.

5. The method of claim 1 , wherein the sorbent material is configured to absorb carbon dioxide.
