A filtration system for a tank includes a filter housing, at least a portion of which is disposed in a tank and in fluidic communication with a dielectric fluid within the tank; at least one filtration element, disposed within the filter housing; and a fluid pump, at least a portion of which is disposed within the filter housing and immersed in the dielectric fluid, the fluid pump in fluidic communication with the at least one filtration element.

Filtration design for immersion cooling tank systems

Described herein is fluorinated dye comprising: a fluorescing coumarin-derived moiety connected to an oligomer of hexafluoropropylene oxide via a non-fluorinated divalent linking group. Such fluorinated dyes are soluble in fluorinated fluids and may be used to detect leaks in various systems such as refrigerant, air conditioning and/or heat transfer systems.

Fluorinated coumarins

An immersion cooling system includes a housing having an interior space; a heat-generating component disposed within the interior space; and a working fluid liquid disposed within the interior space such that the heat-generating component is in contact with the working fluid liquid. The working fluid comprises a compound having Structural Formula (IA) Each Rand Ris, independently, (i) a linear or branched perhalogenated acyclic alkyl group having 1-6 carbon atoms and optionally contains one or more catenated heteroatoms selected from O or N; or (ii) a perhalogenated 5-7 membered cyclic alkyl group having 3-7 carbon atoms and optionally contains one or more catenated heteroatoms selected from O or N.

Fluids for immersion cooling

An optical system including first and second optical elements for guiding light therein. For each optical element, the propagating light enters or exits the optical element through a coupling surface of the optical element. The coupling surfaces of the optical elements face, and align with, each other so that light propagating in one of the optical elements exits the optical element through the coupling surface of the optical element and enters the other optical element through the coupling surface of the other optical element. The coupling surfaces are separated from each other and define a region therebetween. The region is filled with a coolant, the coolant substantially surrounding at least one of the first and second optical elements.
