Abstract
A plurality of segmented components are arranged to form a fixed radial heat exchanger. Each segment is an independent heat exchanger having a core of fluid tubes and air flow corridors between the tubes. Air flow is maintained through the heat exchanger by means of a propeller type fan mounted coaxially with the heat exchanger.
Claims4
A toroidal heat exchanger comprising a plurality of arcuate heat exchanger cores, each for independently effecting the heat content of one of a plurality of vehicle related fluids, each arcuate heat exchanger core being one arcuate segment of said toroidal heat exchanger and each arcuate heat exchanger core having an arcuate inlet header tank and an arcuate outlet header tank connected by a plurality of liquid carrying conduits arranged parallel to the central axis of said toroidal heat exchanger, each arcuate heat exchanger core curved around said central axis of said toroidal heat exchanger further having said inlet and outlet header tanks located at the respective top and bottom of said toroidal heat exchanger.
A toroidal heat exchanger for use in effecting the transfer of heat energy from each of a plurality of said toroidal heat exchanger comprising:
- a first arcuate heat exchanger core, being one arcuate segment of said toroidal heat exchanger, having an arcuate inlet header tank and an arcuate outlet header tank connected together by a plurality of fluid conduits arranged parallel to the central axis of said toroidal heat exchanger, said first arcuate heat exchanger core curved around said central axis further having said inlet and outlet header tanks located at the respective top and bottom of said toroidal heat exchanger;
- a second arcuate heat exchanger core, being a second arcuate segment of said toroidal heat exchanger, having an arcuate inlet header tank and an arcuate outlet header tank connected together by a plurality of fluid conduits arranged parallel to the central axis of said toroidal heat exchanger, said second arcuate heat exchanger core curved around said central axis further having said inlet and outlet header tanks located at the respective top and bottom of said toroidal heat exchanger;
- a third arcuate heat exchanger core, being a final segment of said toroidal heat exchanger, having an arcuate inlet header tank and an arcuate outlet header tank connected together by a plurality of fluid conduits arranged parallel to the central axis of said toroidal heat exchanger, said third arcuate heat exchanger core curved around said central axis further having said inlet and outlet header tanks located at the respective top and bottom of said toroidal heat exchanger whereby said first, second and third arcuate heat exchanger cores are arranged adjacent each other to form said toroidal heat exchanger.
A toroidal heat exchanger for use in effecting the heat content of a plurality of fluids, said toroidal heat exchanger comprising:
- a plurality of arcuate heat exchanger cores each having an inlet header tank and an outlet header tank having respective integral inlet and outlet apertures, said inlet header tank connected to said outlet header tank through a plurality of fluid passages running parallel to the central axis of said toroidal heat exchanger separated by air passages, further said arcuate heat exchanger cores arranged end-to-end around said central axis whereby said toroidal heat exchanger is formed.
