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 Rf 1 and Rf 2 is, 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.
一种浸没式冷却系统包括一个内部空间的外壳;一个放置在内部空间内的发热组件;以及一种工作流体液体,被放置在内部空间内,使得发热组件与工作流体液体接触。工作流体包括具有结构式(IA)的化合物。每个Rf 1和Rf 2都是独立的,(i)是具有1-6个碳原子的线性或分支的
全氟烷基,可选地含有一个或多个选自O或N的链状杂原子;或(ii)是具有3-7个碳原子的
全氟5-7环状烷基,可选地含有一个或多个选自O或N的链状杂原子。
