  • Patent number: 11772019
    Abstract: A method of and system for recovering a dielectric fluid used for immersion cooling of electronic devices, the method including filtering the dielectric fluid to remove a first group of solid contaminants; distilling the filtered dielectric fluid in one or more distillation tanks to produce a vaporized dielectric fluid; separating the vaporized dielectric fluid from less volatile contaminants, such that the vaporized dielectric fluid is introduced as a condensate into a circulation tank; circulating the condensate by pumping the condensate from the circulation tank through one or more filters; filtering the circulating condensate through the filter(s) to remove a second group of contaminants; and returning the filtered condensate to the circulation tank.

  • Patent number: 11778781
    Abstract: A method and system for controlling operation of an immersion cooling system to filter a heat transfer fluid having an immersion cooling tank adapted to contain the heat transfer fluid used to immersion cool a heat-generating object contained therein, the method and system comprises: sampling the heat transfer fluid in the tank; measuring at least one property or parameter of the sampled heat transfer fluid; generating and transmitting measurement data to a control unit; comparing measurement data with respective threshold data using the control unit; and filtering the heat transfer fluid with a filter based on the comparison results of the control unit.

  • Patent number: 11758687
    Abstract: A device for and method of hot swapping one or more electronic devices from an immersion cooling tank having a first opening, the device including a condensing device removably locatable in the first opening of the immersion cooling tank, the condensing device having a condensing coil forming a second opening through which the electronic device(s) is removable and an apparatus coupled to the condensing device for selectively adjusting a height and/or a location of the condensing device about the first opening of the immersion cooling tank.

  • Patent number: 11608217
    Abstract: A device for and method of hot swapping one or more electronic devices from an immersion cooling tank having a first opening, the device including a condensing unit removably locatable in first opening of the immersion cooling tank, the condensing device having a condensing coil forming a second opening through which the electronic device(s) is removable. A retractable cover sheet assembly, under computer control, is positioned to form a sized opening, which may include a containment structure, prior to opening the tank lid to minimize dielectric fluid loss.

  • Patent number: 11101630
    Abstract: Embodiments of busbar assemblies for immersion cooling are described herein. In one embodiment, a busbar assembly can include an insulator block and a busbar. The insulator block can include a first barrier extending from a first end of the insulator block to a second end of the insulator block. The insulator block can a second barrier extending from the first end to the second end. The first barrier can include a first support surface. The second barrier can include a second support surface. The insulator block can include a channel between the first barrier and the second barrier. The channel can extend from the first end to the second end. The busbar can be positioned in the channel. The busbar may have a top surface that is recessed below the first support surface and the second support surface. Other examples may be described and claimed.
