Abstract
A serpentine, multiple pass heat exchanger includes at least one flattened, multiple port tube in serpentine configuration with a plurality of general parallel runs defining at least three hydraulically separate flow paths fins. Fins extend between and are in thermal conducting relation with adjacent ones of the runs and an inlet manifold is located on one end of the tubes with an outlet manifold located on the other. A baffle is located in the outlet manifold and the inlet manifold includes a partition which extends both longitudinally and transversely within the inlet manifold to hydraulically separate one flow path from the inlet port while connecting other flow paths to each other to provide for multiple passes.
Claims10
A serpentine, multiple pass heat exchanger comprising:
- at least one flattened multiple port tubes in a serpentine configuration with a plurality of generally parallel runs defining at least three hydraulically separate flow paths;
- fins extending between and in thermal conducting relation with adjacent ones of said runs for each flow path;
- an inlet manifold on one end of said tube(s) and in fluid communication with the ports therein;
- and
- an outlet manifold on an opposite end of said tube(s) and in fluid communication with the ports therein;
- the cross sectional area of one of said flow paths being greater than the cross sectional area of another of said flow paths with said one flow path being adjacent a back side of said heat exchanger through which a coolant may exit and said another flow path being adjacent a front side of said heat exchanger through which a coolant may enter;
- a baffle in said outlet manifold separating said another flow path and one of the other of said flow paths from the remaining flow path(s);
- said inlet manifold having inlet port through which a fluid may enter said inlet manifold and located adjacent said front side of said heat exchanger and a partition extending both longitudinally and transversely within said inlet manifold to hydraulically separate said one flow path from said inlet port while connecting said another flow path to at least one other flow path other than said one flow path.
