Patent number: 9772126Abstract: A cooling system for transferring heat from a heat load to an environment has a volatile working fluid. The cooling system includes first and second cooling cycles that are thermally connected to the first cooling cycle. The first cooling cycle is not a vapor compression cycle and includes a pump, an air-to-fluid heat exchanger, and a fluid-to-fluid heat exchanger. The second cooling cycle can include a chilled water system for transferring heat from the fluid-to-fluid heat exchanger to the environment. Alternatively, the second cooling cycle can include a vapor compression system for transferring heat from the fluid-to-fluid heat exchanger to the environment.Type: GrantFiled: January 22, 2016Date of Patent: September 26, 2017Assignee: Liebert CorporationInventors: Steven A.

Patent number: 8118084Abstract: An improved precision cooling system for high heat density applications comprises a heat exchanger having more fluid outlet conduits than fluid inlet conduits to optimize the pressure drop across the heat exchanger at a given fluid flow rate. The heat exchanger may be of microchannel or tube fin construction, and the cooling system may utilize single phase or multi-phase pumped or compressed fluids.Type: GrantFiled: May 1, 2007Date of Patent: February 21, 2012Assignee: Liebert CorporationInventor: Thomas E.

Publication number: 20110101118Abstract: A method of preventing condensation on equipment inside a temperature-controlled enclosure comprises measuring the temperature in at least one location inside the enclosure. The temperature inside the enclosure is compared with a safe temperature, at which the risk of condensation is reduced. The temperature inside the enclosure is increased until the safe temperature is achieved. A user is then notified that it is safe to access the enclosure.Type: ApplicationFiled: January 6, 2011Publication date: May 5, 2011Applicant: LIEBERT CORPORATIONInventors: Karl M. CRISS, David A.

Patent number: 7788940Abstract: The disclosure provides an improved cooling system and associated cabinet for electronic equipment, and optionally, a backup ventilation system for cooling related failures. Generally, the disclosure includes a high capacity closed loop refrigeration system in a modified cabinet, while accommodating standard sized computer equipment. Further, the system provides directed heat removal by altering typical airflow paths within the cabinet. The backup ventilation system is powered by auxiliary power in the case of power failure and uses the same fan(s) for ventilation as is used for cooling. The disclosure provides a more efficient, higher capacity cooling cabinet in less space than otherwise known in the art. Further, the cooling system can anticipate heat loads and therefore operate in a predictive capacity by monitoring input power to the electronic equipment and adjusting the cooling for the expected increase or decrease in heat load generated based on the input power.Type: GrantFiled: July 20, 2006Date of Patent: September 7, 2010Assignee: Liebert CorporationInventors: Steven M.

Patent number: 5701837Abstract: A boat dock bumper is provided for protecting the hull of a watercraft when the watercraft is moored to a dock, pier, piling, or like structure, and includes a flexible, generally rectangular-shaped member attachable to the watercraft, a flexible upper portion for resting on the gunwale of the watercraft, and a deformable major body portion which can be conformably positioned contiguous to the hull of the watercraft. Disposed within and extending through the rectangular-shaped member from the upper portion to the major body portion are a plurality of flexible, bendable, elongated batten members which provide support and stability for the rectangular-shaped member when the boat dock bumper is attached to the watercraft.Type: GrantFiled: August 2, 1996Date of Patent: December 30, 1997Inventor: Thomas E.

Patent number: 4568281Abstract: A self-temperature regulating hermetically sealed dental mirror includes a mirror encasement comprised of an inverted metal cup that contains electronic heating and temperature control components secured in its interior cavity by a heat conductive resin base potting material. The external surface of the closed end of the cup is a light reflective surface that functions as a mirror. The open end of the inverted cup is imbedded in a plastic base that is molded around and sealed to the sides of the cup in such a manner that the potting material and electronic components are completely sealed and not exposed to the exterior. A molded handle extends radially outwardly from the base, and electric wire leads for conducting electricity to the heating components are positioned longitudinally through the handle. A male jack plug is molded into the distal end of the handle for connecting the wire leads to a power source.Type: GrantFiled: December 15, 1983Date of Patent: February 4, 1986Inventors: Thomas E.
