Liquid cooling coolant selection: a four factor score
Liquid cooling coolant selection comes down to one question: does the liquid cooling fluid move heat fast, pump cheap, stay safe, and survive the cold? The answer is written in molecular structure. Rank any candidate by a four factor score that weighs thermal conductivity, viscosity, electrical conductivity, and freezing point, then match the winner to your scenario. For data centers the best balance is usually a fluorinated immersion fluid or glycol water, while a cold plate loop wins retrofits on cost. Why liquid cooling beats air cooling by a generational margin Heat leaves a chip in three ways: conduction, convection, and radiation. Air is poor at all three. Air molecules…

Decoding the Dripping Dilemma: Unraveling the Mystery of the Teapot Effect
Do you often encounter this annoying phenomenon: no matter how careful you are, the water poured from the teapot always fails to enter the teacup according to the expected trajectory, but flows along the spout, against the wall of the pot, and onto the table? At this time, have you ever complained about the poor quality of the teapot or that you were not careful enough? In fact, this really cannot be blamed on the teapot or the tea pourer. This is a very common physical phenomenon. The mysterious “teapot effect” In 1965, Israeli physicist Marquez Reina conducted a series of “simple” experiments: pouring tea out of the teapot at…
