A heat exchanger is disclosed comprising a pair of laterally spaced fluid conducting tanks operatively interconnected by a plurality of elongated fluid conducting tubes having sector shaped cross sections and arcuately spaced from one another in a circular pattern to present parallel interfacing sides. A plurality of elongated corrugated fins or air centers each having convolutions of substantially constant height and width to have spaced lines of contact along the width and length of each of the sides of the tubes for maximizing heat transfer and so that the tubes will be optimally supported to provide increased resistance to pressure ballooning and burst. These air centers are standard corrugated rectilinear components that reduce complexity and cost of this circular heat exchanger. This heat exchanger can be arranged in a parallel relationship with a transverse automotive engine and a cooling fan operatively mounted within the heat exchanger can be directly driven by the engine. An annular oil cooler and air conditioner condenser can also surround the heat exchanger.

A heat exchanger having laterally spaced first and second tank portions for receiving heat transferring fluid from a supply of fluid heated by a source of heat energy and after an exchange of heat energy for returning said fluid to said source, a plurality of elongated fluid conducting tubes operatively interconnecting said tank portions to one another, each of said tubes having opposing side walls which diverge from a common inner edge of a minimized width to a common wall to substantially define in cross section the sector of a circle support means provided by an end wall of each of said tank portions for connecting said fluid conducting tubes in a curved pattern adjacent to one another, fluid diverting means in said tank portions so that fluid circulates through said heat exchanger in a serpentined pattern, said side walls of said tubes which facing said side walls of adjacent tubes being disposed at substantially equal distances from each other, a plurality of air center means comprising convoluted heat transfer means defined by a continuous pattern of ridge and groove portions of a substantially constant height operatively interposed between said facing side walls, said ridge portions directly contacting said facing side walls so that said air center means mechanically interconnects and supports said tubes to increase the burst strength thereof and for effectively increasing the external heat radiating surface area of said tubes for augmenting the heat transfer efficiency of said heat exchanger.
