Abstract:
A compact cooling system, comprising:a radial fan having an axis, said radial fan directing air flow outwardly away from said fan axis; a first heat exchanger and a second heat exchanger, said heat exchangers being disposed around said radial fan with first and second headers extending generally in the same direction as said fan axis, said heat exchangers each having: an inlet in said first header, an outlet in one of said first and second headers, a plurality of flat tubes extending between said first and second headers, said plurality of tubes: being substantially parallel between first and second end tubes of said plurality of flat tubes, adapted to carry a fluid between said first and second headers, and spaced from a system front to a system back across said air flow, and said first header including a portion extending beyond one of said first and second end tubes whereby said inlet is in said extending portion of said first header; a system inlet; a first rectangular tube connecting said system inlet to said inlet in said extending portion of said first heat exchanger, said first rectangular tube being proximate and in line with said one of said first and second end tubes of said first heat exchanger and generally disposed in a space along said fan axis bounded by the ends of said extending portion of said one of said first and second headers of said first heat exchanger; and a second rectangular tube connecting said system inlet to said inlet in said extending portion of said second heat exchanger, said second rectangular tube being proximate and in line with said one of said first and second end tubes of said second heat exchanger and generally disposed in a space along said fan axis bounded by the ends of said extending portion of said one of said first and second headers of said second heat exchanger; wherein said first and second rectangular tubes have a major dimension and minor dimension, with said minor dimension extending generally parallel to said fan axis.
