Heat Exchanger Core With Varied-Angle Tubes Abstract Heat exchangers depend for efficiency upon maximizing fluid flow, such as air, through their fins about tubes extending through the fins. The air flow, particularly at the ends of a heat exchanger, can some- times be of a significantly reduced amount owing to flow restrictions caused by the construction of, or arrangement of elements in, a heat exchanger. A core of a heat exchanger of the present invention utilizes a relatively varied angular arrangement for tubes in the core which improves air flow, particularly at the ends of the core. Air flow is thus improved over a portion of the heat exchanger to increase heat transfer, as well as purging of debris, for the folded or zigzag core arrangement described.
