Enhancement of boiling heat transfer in di-electric fluids.

MetadataShow full item record
Direct application of two-phase heat transfer in the liquid cooling of electronic components in flouorinated hydrocarbons (FC-72), is severely inhibited by the excessive amount of superheat required to initiate nucleate boiling. To conduct an experimental study of nucleate pool boiling of FC-72, an experimental test chamber was constructed. This chamber utilized five horizontal platinum wires of 0.05 mm diameter spaced 2.0 cm vertically from each other. The lowest wire was progressively heated from the natural convection region through nucleate boiling, and a study was made on the effects of the boiling wake plume on the heat transfer rate of the upper wires.
