| Zusammenfassung: | Heat exchange inefficiencies found in round tube plate fin heat exchangers are eliminated in an aluminum heat exchanger that includes first and second headers (
20
), (
22
) and at least one flattened tube (
24
), (
70
) extending between the headers (
20
), (
22
). A plurality of generally parallel tube runs are defined and each has opposite edges. A plurality of plate fins (
26
), (
50
) are arranged in a stack and each has a plurality of open ended slots (
34
), one for each run of the tubes (
24
), (
70
). Each of the tube runs (
24
), (
70
) is nested within corresponding slots (
26
) and the fins (
26
), (
50
) with one of the edges (
40
) of the tube runs extending outwardly of the corresponding fin (
26
). The assembly is brazed together. |
