Patent number: 11965846Abstract: A system for detecting contamination in a two-phase immersion cooling system based on temperature differences between component surface temperature and fluid temperature, a previous component surface temperature and a present component surface temperature and a component surface temperature and a component surface temperature threshold value. Large differences between the component surface temperature and the fluid temperature or between the component surface temperature and a previous component surface temperature or a component surface temperature exceeding a component surface temperature threshold value may indicate contaminants in the fluid that are inhibiting the ability for the component to effectively transfer heat to the fluid. A temperature monitoring system may monitor the temperatures and communicate with a service system to apply corrective measures before the residue can cause significant damage to an information handling system.Type: GrantFiled: April 23, 2021Date of Patent: April 23, 2024Assignee: Dell Products L.P.Inventors: Jon Taylor Fitch, Steven Embleton, David Lyle Moss

Patent number: 11435410Abstract: A system for detecting contamination in a two-phase immersion cooling system based on current leakage between two combs on a printed circuit board. A first comb is opposite a second comb, wherein each finger of the first comb is positioned between two adjacent fingers on the second comb. The combs are positioned near a heat source in the liquid portion of the fluid. As the fluid boils, contaminants are distilled out of the fluid. Acidic contaminants deposited on either comb may cause metal migration to occur, resulting in bridging between two combs. A current sensor may detect the current leakage and send a signal to allow the information handling system, the fluid, or the cooling system to be serviced before damage occurs to the information handling system.Type: GrantFiled: February 24, 2021Date of Patent: September 6, 2022Assignee: DELL PRODUCTS L.P.Inventors: Jon Taylor Fitch, Steven Embleton, David Lyle Moss

Patent number: 11429165Abstract: A system for detecting residue in a two-phase immersion cooling system based on contact resistance. A structure is formed to represent a type of connection between a component and a connector. The structure is positioned near a heat source in the two phase fluid in its liquid state. As the fluid boils, residues are deposited on the structure. An increase in the current resistance across the structure may indicate the presence of a residue or corrosion caused by the residue. Structures may be formed using materials that are similar to existing connections in the information handling system. A heating element may generate more heat than existing components such that the system detects the presence of contaminants with sufficient time to allow less expensive and less intensive corrective measures.Type: GrantFiled: February 5, 2021Date of Patent: August 30, 2022Assignee: Dell Products L.P.Inventors: Jon Taylor Fitch, Steven Embleton, David Lyle Moss

Publication number: 20220252523Abstract: A system for detecting residue in a two-phase immersion cooling system based on changes in the intensity of energy reflected off a reflective surface. An energy source is positioned at an incident angle relative to a reflective surface and an intensity sensor is positioned at a target reflected energy angle relative to the reflective surface, wherein the intensity sensor detects light or other energy reflected off the reflective surface. If residues are deposited on the reflective surface, the reflectivity of the residue will change the reflected energy angle or otherwise change the amount of energy reflected toward the sensor. A heating element may generate more heat than existing components such that the system detects the presence of residues with sufficient time to allow less expensive and less intensive corrective measures.Type: ApplicationFiled: February 5, 2021Publication date: August 11, 2022Inventors: Jon Taylor Fitch, Steven Embleton, David Lyle Moss

Patent number: 7826216Abstract: An information handling center includes an information handling system (IHS) rack configured to receive cooled fluid from a pressurized plenum. The IHS rack includes at least one ventilator that is operable to cause cooled fluid to be drawn from the pressurized plenum into the IHS rack. A cooling fluid supply unit is coupled to the pressurized plenum and operable to cool a fluid passing through the cooling fluid supply unit and direct that cooled fluid into the pressurized plenum. A fluid flow control is located in the cooling fluid supply unit and coupled to a pressure sensor that is operable to determine a pressure in the pressurized plenum. The fluid flow control is operable to adjust the flow rate of the fluid passing through the cooling fluid supply unit based on the pressure determined by the pressure sensor.Type: GrantFiled: December 3, 2008Date of Patent: November 2, 2010Assignee: Dell Products L.P.Inventor: David Lyle Moss

Patent number: 5793610Abstract: The present invention provides a cooling fan system for a chassis configured to contain heat generating electrical components and to assume horizontal and vertical alternative operating orientations. The cooling fan system includes a support member securable within the chassis and having an air flow opening formed therein.
