I agree that there will always be "knock off" products of questionable quality. By the way, the fluid is 99.9% of the time water and the pressure is set by the vapor pressure of the fluid. By the time heat pipes began to be used by the computer industry the designs had been pretty well established in the military and specialty markets. The wicks are for the most part sintered copper powder (sometimes, grooves, mesh or wires) and all commercial applications use water for the working fluid.
No announcement yet.
