| 摘要 |
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.
