description abstract | An experimental study of forced convection in impinging flow, using fluorocarbon FX3250 and a simulated electronic chip, was performed. A test section consisting of a 35 mm long, 1 mm wide slot nozzle in a 2 mm thick plate offset 2 mm from the heat source was used. The simulated chip array consisted of five foil strip (4 mm wide) heaters, positioned with the center strip directly beneath the slot nozzle. The velocity of the coolant was varied from 0.53 to 5 m/s, and the subcooling in the range from 2 to 21 K. The experiments were conducted focusing on two cases. First, only the center strip was heated. Second, all the heaters were energized, and the strip-by-strip variations of heat transfer were measured. The critical heat flux (CHF) on the center strip, determined by sensing the onset of oscillations and subsequent rapid rise of foil temperatures, was found considerably lower than those predicted by the existing correlations. It is pointed out that the thermal mass of the test heater could be an important factor for the CHF. The heat transfer behavior of other strips showed channel-flow or jet-impingement mode depending on the strip location and the coolant flow rate. [S1043-7398(00)00202-4] | |
