ABSTRACT:
Heat exchangers depend for efficiency upon optimum fluid flow, such as air, through their fins and about tubes extending through the fins. The air flow, particularly at the ends of a heat exchanger, can sometimes be of a significantly reduced amount owing to the construction of, or arrangement of elements in, the heat exchanger. First and second cores (12,14) of a heat exchanger (10) are positioned in a general "V" configuration with their inlet ends (24,42) adjacent one another. Apparatus (64) is provided upstream of the inlet ends (28,46) of the cores (12,14) to direct the air flow in a preselected orientation to inlet surfaces (20,38) of the cores (12,14) at the ends (28,46) of the cores (12,14). Air flow is thus improved over a portion of the heat exchanger (10) to increase its heat transfer efficiency.
