  • a heat exchanger sometimes referred to as a radiator, typically includes several channels or tubes through which a fluid selectively flows. Heat which is generated by a device or assembly (e.g., an engine) is transferred to or "exchanged with” the movably contained fluid and the fluid is then cooled and communicated to a reservoir, thereby allowing the fluid to cool before it "re-circulates" through the exchanger.
  • the transfer or the exchange of heat is typically enhanced by "fins” or other members which cooperatively interconnect the tubes and which increase the amount of surface area that the produced heat contacts and/or the amount of time that the produced heat is in heat exchanging contact with the tubes and the heat exchanger assembly.

Adjacent portions 14 of a tube 12 are integrally connected by a portion 17 which is substantially similar to portion 16. Further, as shown, the cross sectional area of each portion 14 is generally bulbous or substantially oval and each portion 14, of a tube 12, is generally symmetrical about an axis 18 which also and substantially comprises the longitudinal axis of symmetry of the corresponding cross sectional area of the portion 16 of that tube 12 (e.g., the term "corresponding" means that the referenced cross sectional area of portion 16 is substantially co- planar to the referenced cross sectional area of the portion 14) .
  • each portion 14 has a substantially identical and generally oval shaped cavity 20 which is longitudinally coextensive to the portion 14 and which terminates upon opposed and open ends 22, 24 of the portion 14.

Opposed ends 22, 24 are respectively sealingly secured within header assemblies 26, 28 by a "friction fit", brazing, welding, and/or by use of conventional fasteners or sealer type members and header assembly 26 is coupled to a source of fluid (not shown) by conduit assembly 30 and header assembly 28 is coupled to the same source of fluid (not shown) by conduit assembly 32.

  • fluid 31 is communicated into the tubes 12 by the cooperation of conduit assembly 30, header assembly 26, and open ends 22.

  • each portion 14 of a tube 12 is placed between portions 14 of adjacent tubes 12, thereby allowing a convoluted or serpentine flow path, such as flow path 35, to be created, thereby increasing the amount of time that the warm air 33 (the air which "carries" the heat which is generated by the. device or assembly) remains in heat exchanging contact with the tubes 12, thereby obviating the need for fins or similar assemblies and allowing the heat exchanger to have a relatively uncomplicated overall design.
  • tubes 12 may be extruded and/or constructed by "traditional brazing, welding, or other tube forming techniques (such as folding) , thereby obviating the need for tubular seams, thereby reducing failure or fluid leakage and increasing resistance to internal pressure.
  • the contained fluid may therefore traverse the heat exchanger 10 at a relatively high pressure which allows for a relatively efficient heat transfer.
