Abstract
Structured thermal transfer article comprising a plurality of metal bodies and a plurality of interstitial elements disposed between and connecting the plurality of metal bodies to one another. The metal bodies comprise an inner portion comprising a first metal and an outer portion comprising an alloy comprising the first metal and a second metal. The interstitial elements comprise the alloy of the outer portion.
Description
technical field [0001] The present invention relates generally to structured thermal transfer articles. More particularly, the present invention relates to shaped porous metal articles and methods of making and using the same. Background technique [0002] A cooling system for a heat dissipating element includes an evaporating or boiling fluid. The steam produced is then condensed using external means and sent back to the boiler. In order to improve the heat transfer of the fluid at the boiler, porous boiling surfaces can be used. [0003] A variety of porous boiling surfaces can be used including, for example, coatings made by flame or plasma spraying. But controlling porosity and uniformly coating three-dimensional substrates can be difficult using these processes. Other known coatings include conductive particles combined with an organic binder. These coatings typically have poor bulk thermal conductivity and thus require precise thickness control, which is difficult...
