## 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.

## Claims

### Claim 1

A heat exchanger assembly, comprising:
a first packed bed having a first fin layer comprising first lanced offset fins, a second fin layer comprising second lanced offset fins, and a first sorbent material disposed within the first packed bed; and
a second packed bed in thermal communication with the first packed bed, the second packed bed having a third fin layer and a second sorbent material disposed within the second packed bed,
wherein the first lanced offset fins are staggered with the second lanced offset fins to facilitate multi-directional airflow and allow for a compact configuration of the first packed bed.

### Claim 2 (depends on 1)

The heat exchanger assembly of claim 1, wherein the first packed bed comprises a perforated sheet brazed with the first fin layer.

### Claim 3 (depends on 1)

The heat exchanger assembly of claim 1, wherein the first fin layer, the second fin layer and the perforated sheet comprise aluminum.

### Claim 4 (depends on 1)

The heat exchanger assembly of claim 1, wherein the first sorbent material and the second sorbent material are configured to adsorb and desorb carbon dioxide.

### Claim 5 (depends on 4)

The heat exchanger assembly of claim 4, wherein heat generated exothermically by adsorption of carbon dioxide by the first sorbent material is transferred to the second packed bed.

### Claim 6 (depends on 5)

The heat exchanger assembly of claim 5, wherein the second packed bed receives heat from the first packed bed, and wherein the heat exchanger assembly is substantially isothermal.
