Abstract: An immersion cooling system and methods for operating the system are described. The system can comprise a vessel configured to hold thermally conductive, condensable dielectric fluid; a pressure controller to reduce or increase an interior pressure of the vessel; a computer component configured to be at least partially submerged within the dielectric fluid; and a fluid circulation system configured to draw the dielectric fluid from a sump area of the vessel, pass the dielectric fluid through a filter and deliver the dielectric fluid to a bath area of the vessel.

Abstract: A turbine has a first and second inner wall, an inner casing and a shield element. The first and second inner walls are mounted to the inner casing such that an inner volume for working fluid is separated from an outer volume for cooling fluid. The first and second inner walls and inner casing are arranged to form a cavity in outer volume. The shield element is arranged inside cavity to separate cavity in an inner and outer region in a radially outer position to the inner region. A gap is formed between the first and second inner walls for working fluid between the inner volume and inner region. The shield element is arranged in cavity to form a fluid inlet for injecting cooling fluid from outer region to inner region for generating a predefined recirculation of working fluid and cooling fluid inside inner region.

Abstract: A method for cooling a component of a turbine is provided, wherein a fluid with a pressure below 1 bar is guided away from the component. Moreover, a turbine is described comprising a component, a conduit which is connected to the component so that a fluid can be guided away from the component, and a fluid discharge which is connected to the conduit. The fluid discharge is constructed so that it removes a fluid with a pressure below 1 bar.
