Patent number: 8011536Abstract: A dispenser of cooled or heated liquid which in one embodiment is a server cart for an aircraft. To avoid the need for a pump, the reservoir has a cooling or heating heat exchanger that helically coils around the main reservoir, which cools from the top down or heats from the bottom up, forming a counter current. The reservoir is connected to at least two conduits, one near the cooler top of the reservoir and one near the relatively warmer bottom of the reservoir. The two conduits connect to one another at a distance from the reservoir forming a dispensing passage, thereby allowing fluid to constantly circulate through the dispensing passage due to difference in the specific gravity in the fluid caused by the temperature difference. The elimination of the pump device is especially desirable for weight sensitive environments such as an aircraft.Type: GrantFiled: August 3, 2006Date of Patent: September 6, 2011Assignee: Airbus Deutschland GmbHInventors: Matthias Witschke, Wolfgang Ebigt, Marco Mundt, Peter Detjen

Publication number: 20090304531Abstract: An integrated pumping module for use in a thermal management system, for example for a fuel cell. The integrated pumping module includes a diverting or mixing valve closely coupled to a pump element, such as the volute chamber of a centrifugal pump. The valve chamber and the pump chamber are closely and directly coupled through a connecting passage so as to minimize pressure drop as a liquid coolant passes through the connecting passage from the valve chamber to the pump chamber. A bypass inlet and outlet opening are provided in the valve chamber to permit all or a portion of the coolant flow to be diverted to a radiator once the coolant reaches a predetermined temperature. The integrated pumping module may also be provided with a filter housing into which a portion of the coolant flow may be diverted.Type: ApplicationFiled: June 5, 2008Publication date: December 10, 2009Applicant: DANA CANADA CORPORATIONInventor: Doug Vanderwees
