Around 1995-1997, I worked at a nuclear engineering consulting company where there was a thermo engineer VP who was also a professor of thermodynamics in microgravity research. Several times, he opined heat pipes would be amazing for cooling the new generation of very hot PC CPUs in desktops and laptops because these were what were used in satellites to remove heat from systems that needed to radiate heat away from point heat sources to cold sources elsewhere. And, sure enough, not a year later did Zalman have a giant copper block heatsink with a heatpipe for cooling Socket A CPUs.
If someone weren't familiar, heat pipes are typically self-starting, passive cooling loops that use a sub-atmospheric sealed pressure chamber filled a very high latent of vaporization coolant (i.e., water or ammonia) and usually a wick core or channelized piping surface to make the journey from cold to hot without gravity assistance. (Passive two-phase fluid flow, even with gravity, is very painful.) Mobile phone vapor chambers are basically extremely short heat pipes. I guess one could make an aluminum or lithium as coolant heat pipe for rocket engines, scramjets, reactors, or blast furnaces if they had exotic enough materials to contain them.
