Cup (extreme cooling)
See also: Cup
In Extreme cooling, a cup is a Récipient built in a Métal which leads very well the heat, intended to contain a substance which will be used to cool the component located under the cup.
Description
A cup measures in general from 20 to 30 Centimètre S height even more, round or square section most of the time, and consists of Cuivre or Aluminum for example. The thickness of the bottom is from approximately 1 Centimètre, seldom more than 2 in order to preserve optimal performances. The bottom of the cup comprises sometimes a refines, in order to offer more a large surface of contact between the cup and the Liquide present inside this one.
Use
The cups are never used for the daily cooling of a Ordinateur, because they require a frequent filling: most of the time they are used with Azote liquidates (LN2 cooling) or of the carbonic Glace (Dry ice cooling) for example, which vaporizes in the air then, and can thus be used only for one limited time if the cups are not filled régulièrement.The use of cups also requires a horizontal Mother chart because of the Gravité, i.e. posed flat, without turn, where in the majority of those the Mother chart is vertical.
The cups are fixed most of the time on CPU, GPU, and sometimes on the Northbridge, in order to cool them.
The products used having Temperature S lower than -70 °C (hottest being in general the carbonic Ice, with -78 °C) and lacks it facility of use make cups a technique reserved for the Extreme cooling, where the only goal is to reach the lowest possible Température S.
