"...will it ever fly in the datacenter, I doubt it but there are better ways."
I appreciate your sentiments. Believe me, I appreciate any and all skepticism concerning immersion cooling. After 15 years working as a liquid cooling Thermal Engineer, I can TRULY appreciate it.
I also appreciate the cost and complexity of all the liquid cooling technologies that HAVE succeeded (immersion among them). They include pumps, quick couplings, heat exchangers, manifolds, tubing, clamshells, hermetic IO connectors, and risk that will ultimately prove unacceptable in the context of commodity computational electronics, at least so long as there is a simpler, safer, cheaper and more efficient technology. I think this may be it. I’d like to know of a better way.
