Operating Principles of Rotating Unions
plants. In order to obtain a long service life and maximum productivity of the rotating union, the coolant is to be filtered according to ISO 4406:1999 Code 17/15/12, SAE 749 Class 5 or NAS 1638 class 8, maximum particle size 60 u (fig. 12). Comparison: Pumps (fixed piston as well as variable...
The Position of the Supply Lines and Drainage as Well as Their Influence on the Efficiency and Service Life of a Rotating Union
to ISO 4406:1999 Code 17/15/12, SAE 749 Class 5 or NAS 1638 class 8, maximum particle size 60 u. Comparison: Pumps (fixed piston as well as variable volumes) normally require coolant filtration according to ISO 4406, Code 16/14/11 or better - in other words: They only tolerate half as much...

Designing a Liquid Cooling Loop for High-Performance Systems
). The board generates waste heat, which is transferred from the board to the thermally conductive plate, and then to the liquid coolant that flows through the cold plate. Typically, the fluid path matches the hot spots on the board. The heated coolant is then pumped through the heat exchanger, where...
