Heat exchanger with louvered fins
The present application provides a heat exchanger for exchanging heat between a first fluid and a second fluid. The heat exchanger may include a number of fin plates and a number of tubes extending though the fin plates with the first fluid therein. The fin plates may include a number of louvers extending between the tubes such that the second fluid flows through the louvers.
1. A heat exchanger for exchanging heat between a first fluid and a second fluid, comprising:
a plurality of fin plates;
a plurality of louvers disposed on each fin plate of the plurality of fin plates;
wherein each fin plate of the plurality of fin plates includes a pair of attachment flanges;
wherein adjacent fin plates of the plurality of fin plates are attached together via the attachment flanges; and
wherein the attachment flanges comprise semi-circular bosses running along sides of each fin plate of the plurality of fin plates.
2. The heat exchanger of claim 1 , wherein each louver of the plurality of louvers comprises an angled slat that includes a leading edge that extends above a planar portion of each fin plate of the plurality of fin plates and a trailing edge that extends beneath the planar portion of each fin plate of the plurality of fin plates.
3. The heat exchanger of claim 1 , wherein each angled slat comprises an angle of fifteen degrees (15°) off of the horizontal.
4. The heat exchanger of claim 1 , wherein the heat exchanger comprises a plurality of fin plate columns.
5. The heat exchanger of claim 1 , wherein each fin plate of the plurality of fin plates comprises a plurality of tube apertures.
6. The heat exchanger of claim 5 , wherein each aperture of the plurality of tube apertures comprises a collar.
7. The heat exchanger of claim 6 , wherein each collar comprises a top mating flange and a bottom mating flange.
8. The heat exchanger of claim 1 , wherein the plurality of fin plates are made of aluminum.
9. The heat exchanger of claim 1 , further comprising a louver airflow path that passes between adjacent louvers of the plurality of louvers.
10. The heat exchanger of claim 9 , wherein the louver airflow path reduces an airflow boundary of the plurality of fin plates.
11. The heat exchanger of claim 1 , wherein the second fluid comprises a flow of air.
12. A method of exchanging heat between a first fluid and a second fluid in a fin and tube heat exchanger, comprising:
flowing the first fluid through a plurality of tubes;
flowing the second fluid between a plurality of fin plates, the plurality of tubes extending through the plurality of fin plates, each fin plate of the plurality of fin plates comprising a plurality of louvers;
exchanging heat between the first fluid and the second fluid;
wherein each fin plate of the plurality of fin plates includes a pair of attachment flanges;
wherein adjacent fin plates of the plurality of fin plates are attached together via the attachment flanges; and
wherein the attachment flanges comprise semi-circular bosses running along sides of each fin plate of the plurality of fin plates.
13. The method of exchanging heat of claim 12 , further comprising:
wherein each louver of the plurality of louvers comprises an angled slat that includes a leading edge that extends above each fin plate of the plurality of fin plates and a trailing edge that extends beneath each fin plate of the plurality of fin plates; and
wherein the angled slats reduce a boundary of airflow on the plurality of fin plates.
14. A heat exchanger for exchanging heat between a first fluid and a second fluid, comprising:
a plurality of fin plate columns;
a plurality of tubes extending through the plurality of fin plate columns and configured to flow the first fluid therethrough;
wherein each fin plate of the plurality of fin plate columns comprises a plurality of louvers extending between the plurality of tubes, the plurality of louvers configured to direct a flow of the second fluid through the plurality of louvers;
wherein each fin plate of the plurality of fin plate columns includes a pair of attachment flanges, each attachment flange comprising a semi-circular boss;
wherein adjacent fin plates of the plurality of fin plate columns are attached together via the attachment flanges; and
wherein the attachment flanges comprise semi-circular bosses running along sides of each fin plate of the plurality of fin plate columns.
15. The heat exchanger of claim 14 , wherein each louver of the plurality of louvers comprises an angled slat that includes a leading edge that extends above a planar portion of each fin plate of the plurality of fin plate columns and a trailing edge that extends beneath the planar portion of each fin plate of the plurality of fin plate columns.
