Appeal No. 97-3006
Application 08/571,032
the merits of this rejection.
Hoshino discloses a refrigerant condenser 10 composed of
headers 13 and 14, coolant inlet and outlet pipes 16 and 18,
and a core consisting of a plurality of planar tubes 11 and
corrugated fins 12. Each of the headers includes an internal
partition 20 and 21 for “turning” the refrigerant flow path
through the condenser (see Figure 8). In discussing the
provision of a core which enhances heat exchange efficiency,
Hoshino indicates that a delicate balance must be struck
between the various dimensional characteristics of the tubes
11 and fins 12 (see column 5, line 59, through column 6, line
38).
Guntly also discloses a refrigerant condenser composed of
headers 10 and 12, coolant inlet and outlet fittings 26 and
32, and a core consisting of a plurality of flattened tubes 20
and serpentine fins 34. In contrast to the Hoshino condenser,
Guntly’s headers do not include internal partitions. As a
result, the coolant flows through the condenser in
hydraulically parallel fluid flow paths with no turns. Like
Hoshino, Guntly is concerned with improving the heat exchange
