Abstract
The present paper reports the data of forced convection boiling heat transfer from a 2 cm × 2 cm simulated chip to a fluorocarbon coolant (FX3250) in a parallel-plate channel. The experimental parameters were the channel height (1 and 5 mm), the surface of the simulated chip (flat and micro-finned), and the coolant velocity (0.125 - 4 m/s). The effectiveness of longitudinal micro-fins (0.5 mm high × 0.5 mm wide) in heat transfer enhancement was studied. The experimental results suggest that, in narrow channels, a phenomenon known as 'slugging' could cause boiling crisis at low heat flux. Also, the effect of foreign gas could be diminished in narrow channels.
