A radial flow heat exchanger for heating or cooling a fluid includes a sealed fluid manifold for passage of fluid. A sealed fluid receiving hub is spaced interiorly of the interior peripheral portion of the manifold and includes a passageway for passage of fluid into or out of the heat exchanger. A plurality of separate and spaced fluid flow tubes are disposed between the manifold and the hub. Each of the tubes are in sealed fluid communication with the manifold at one end and the other end is in sealed fluid communication with the hub. A fin assembly is positioned between the manifold and the hub and includes a heat conducting material arranged at spaced intervals between the manifold and the hub, the heat conducting material including a plurality of spaced apertures through which tubes pass. The heat conducting material is in intimate heat conducting contact with the tubes whereby fluid flowing between the manifold and the hub flows into each of the tubes in a radial direction between the manifold and the hub and wherein the heat conducting material of the fin assembly operates to give up or pick up heat from the fluid through the wall of the tubes.

1. A radial heat exchanger for heating or cooling a fluid, comprising:a sealed fluid manifold for receiving and for passage of fluid from an outside source into or out of said heat exchanger and having an interior peripheral portion, a sealed fluid receiving hub spaced interiorly and radially with respect to said interior peripheral portion of said manifold and including a passageway for passage of fluid from or to an outside source into or out of said heat exchanger, a plurality of separate and spaced fluid flow tubes, each having an inner and outer wall and a first end and second end, the first end of each tube being in sealed fluid communication with said manifold, the second end of each tube being in sealed fluid communication with said hub, said fluid to be heated or cooled flowing through said tubes in one direction between said fluid manifold and said hub, said fluid to be heated or cooled either flowing into said manifold from an outside source and then into and through said tubes to said hub or said manifold receiving flow of fluid from said tubes for discharge of the same out of said heat exchanger, a fin assembly positioned between said manifold and said hub, said fin assembly including a heat conducting material arranged at spaced intervals between said manifold and said hub, said heat conducting material arranged in a spiral and including a plurality of spaced apertures therein for passage therethrough of said tubes, said fin assembly having a progressively increasing surface area between said manifold and said hub whereby the maximum surface area of said fin assembly in the region of said manifold and the minimum surface area is in the region of said hub, said heat conducting material being disposed in a generally annular orientation between said hub and said manifold, and said heat conducting material being in intimate heat conducting contact with the outside wall of each said tube whereby fluid flowing between said manifold and said hub flows into each of said tubes in a radial direction between the manifold and said hub and wherein said heat conducting material of said fin assembly operates to give up or pick up heat from said fluid through the wall of said tubes.
