Patent number: 11337340Abstract: A cooling system for a computer server is disclosed. The system includes a flow divider within the server enclosure interior constructed to create a continuous flow path. At least one fan is positioned within the flow path. An inlet air valve is positioned to regulate airflow across the server input air vent. Likewise an outlet air valve is positioned to regulated airflow across the server output air vent. A controller is connected to the fan and the systems has two configurations.Type: GrantFiled: September 30, 2019Date of Patent: May 17, 2022Assignee: Chilldyne, Inc.Inventor: Steve Harrington

Patent number: 11317535Abstract: A reliable, leak-tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump and/or an air compressor in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. Alternatively, the system can use a single vacuum pump and a valve assembly to circulate coolant. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected. Leak detection and mitigation structures are also disclosed. Various turbulators are also provided, as well as a system and method for optimizing the heat transfer characteristics of a heat exchanger to minimize total energy requirements.Type: GrantFiled: October 12, 2017Date of Patent: April 26, 2022Assignee: Chilldyne, Inc.Inventor: Steve Harrington

Patent number: 11175102Abstract: A liquid-cooled cold plate for removing heat from a heat-generating component is disclosed. The liquid-cooled cold plate includes a lower heat transfer plate with a flat component contact surface constructed to make thermal contact with the heat-generating component, and a plurality of parallel turbulator channels, holding a plurality of turbulators, the channels having walls that extend away from the component contact surface. The liquid-cooled cold plate also includes a lid forming a liquid tight seal with the lower heat transfer plate. The lid has an inlet end with an inlet port in fluid connection with an inlet channel manifold that allows for fluid communication between the plurality of parallel turbulator channels and the inlet port. The lid also has an outlet end with an outlet port in fluid connection with an outlet channel manifold that allows for fluid communication between the plurality of parallel turbulator channels and the outlet port.Type: GrantFiled: April 26, 2021Date of Patent: November 16, 2021Assignee: Chilldyne, Inc.Inventors: Steven Merrill Harrington, Carl Eugene Tedesco

Patent number: 10920772Abstract: A pump with two independent motors is disclosed. The first motor is mechanically connected to a first rotor comprising a first plurality of teeth radiating from the center of the first rotor. The second motor is mechanically connected to a second rotor comprising a second plurality of teeth radiating from the center of the first rotor, wherein the first plurality of teeth meshes with the second plurality of teeth. A sealed case may house the first and second rotors, and the case may include a suction inlet and a pressure outlet. Rotating the rotors propels a liquid from the suction inlet to the pressure outlet. Because the motors are independent of each other, when one motor fails to rotate the other motor will rotate both rotors and maintain the propelling liquid from the suction inlet to the pressure outlet. The pump may be a gear pump or a rotary lobe pump.Type: GrantFiled: November 12, 2017Date of Patent: February 16, 2021Assignee: Chilldyne, Inc.Inventor: Steve Harrington

Patent number: 10582641Abstract: A central distribution unit (CDU) for circulating coolant is disclosed. The CDU may operate under negative pressure and can have a number of operation modes including: normal operation, pump priming, fill, drain, purge and vacuum test. The CDU includes various valves, pumps and sensors, the placement and actuation of which transitions the CDU into the various modes.Type: GrantFiled: November 12, 2017Date of Patent: March 3, 2020Assignee: CHILLDYNE, INC.Inventor: Steve Harrington

The system may use a vacuum pump and a liquid pump in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. The system provides both air and liquid cooling so that if the liquid cooling system does not provide adequate cooling, the air cooling system will be automatically activated. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected.Type: GrantFiled: July 10, 2013Date of Patent: October 13, 2015Assignee: Chilldyne, Inc.Inventor: Steve Harrington

Publication number: 20140373933Abstract: A connector for use in a negative pressure coolant system is disclosed. The connector connects coolant system circulating to an electrical component thereby allowing the coolant to circulate through the electrical component. The connector is made up of two components, a component side connector and a pump side connector, and can be in three positions: disengaged, semi-engaged and fully-engaged. An electrical component can be drained of its coolant while the connector is shifted from the fully-engaged position, to the semi-engaged position and to the disengaged position. This can be accomplished without shutting down the negative pressure coolant system, thus allowing a particular electrical component to be disconnected without affecting the cooling efficiency of other electrical components connected to the system. Because the coolant is drained, it will not spill on the electrical component and cause damage.Type: ApplicationFiled: May 28, 2014Publication date: December 25, 2014Applicant: CHILLDYNE, INC.Inventors: Steve Harrington, Peter C.
