Abstract:
1. A heat exchanger assembly for cooling an electronic device comprising; a housing defining a boiling chamber extending along an axis between opposite ends for containing a refrigerant to undergo a liquid-to-vapor-to-condensate cycle, a plurality of first condensing tubes extending axially in one direction from said housing at a first predetermined angle from said axis and a plurality of second condensing tubes extending axially in an opposite direction from said housing at a second predetermined angle from said axis for condensing vapor boiled from the refrigerant, and said first condensing tubes extending below said axis and said second condensing tubes extending above said axis; wherein said housing has a top wall and a bottom wall both extending axially and a first end wall and a second end wall both extending from said bottom wall upwardly and outwardly to said top wall; wherein said first condensing tubes extend perpendicular from said first end wall; and wherein said second condensing tubes extend upwardly and outwardly from said top wall of said housing adjacent to said second end wall.
