Abstract:

Direct application of two-phase heat transfer in the liquid cooling of electronic components in fluorinated hydrocarbons FC-72, is severely inhibited by the excessive amount of superheat required to initiate nucleate boiling. This phenomenon is well documented. To experimentally study the effects of nucleate pool boiling, a test chamber was constructed. This chamber utilized a substrate with nine chips on it and a platinum wire of 0.05 mm diameter. The wire was progressively heated to produce a plume of increasing intensity. A study was made of the effects of the boiling wake from the wire on the heat transfer from the chips.
