Patent number: 10295263Abstract: A technique facilitates removal of heat. The technique involves moving a process fluid through a buffer tank which is combined with a heat exchange system. The heat exchange system includes a conduit carrying a coolant fluid which removes excess heat from a heat source. The conduit is routed to the buffer tank so that the cooler process fluid moving through the buffer tank is able to remove heat from the coolant fluid before it is routed back to the heat source for continued heat removal. In a well application, for example, a heat source, e.g. an electric motor, may be located on a transport vehicle and cooled by the coolant fluid. The heat transferred to the coolant fluid from the heat source is removed by routing the coolant fluid through the conduit associated with the buffer tank. This enables the cooler process fluid in the buffer tank to be used in lowering the temperature of the coolant fluid.Type: GrantFiled: December 5, 2014Date of Patent: May 21, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jonathan Wun Shiung Chong, Rod William Shampine, Garud Bindiganavale Sridhar, Christopher Joseph Decker, Gregoire Omont, Rajesh Luharuka

Patent number: 9902430Abstract: A baffle assembly includes a body, and a vehicle includes a bumper beam and the baffle assembly. The body includes an edge facing outwardly away from the body. A region of the edge includes a plurality of supports spaced from each other. The baffle assembly further includes a seal member secured to the edge of the body. The seal member includes a plurality of protrusions spaced from each other and interleaved with the plurality of supports such that the protrusions and the supports cooperate with each other in an alternating pattern which creates an area configured to absorb energy when a force is applied in the region.Type: GrantFiled: February 11, 2016Date of Patent: February 27, 2018Assignee: GM Global Technology Operations LLCInventors: Scott A. Sytsma, Ana Isabel Payro Romero, Fulgencio Sergio Mendez Morales

Patent number: 9896942Abstract: A turbine airfoil has a suction side wall and a pressure side wall of an airfoil cavity, through which a cooling fluid flows for cooling of the side walls. The suction side wall has one or more protrusions extending therefrom into the airfoil cavity. The protrusions are arranged such that: a number of the one or more protrusions on the suction side wall is higher than a number of protrusions on the pressure side wall; and/or a protrusion density on the suction side wall is higher than a protrusion density on the pressure side wall, and/or a total protrusion surface area on the suction side wall is larger than a total protrusion surface area on the pressure side wall, so that the heat transfer from the suction side wall to the cooling fluid is higher compared to that of the pressure side wall during operation of the turbomachine.Type: GrantFiled: October 2, 2012Date of Patent: February 20, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventor: Andrew Shepherd

Patent number: 9786969Abstract: A vehicle traction battery assembly is provided. The vehicle traction battery assembly may include an array of battery cells, a thermal plate in thermal communication with the array and defining a coolant path, and an electromagnet. The electromagnet may be positioned proximate to the path and configured to selectively output a magnetic field to influence movement of magnetic particles within coolant flowing through the path to control the flowing. The assembly may also include at least one sensor located proximate to the array and configured to output a signal indicative of a temperature of at least one of the battery cells. A controller may be configured to, in response to the signal, direct the electromagnet to adjust the magnetic field.Type: GrantFiled: November 11, 2014Date of Patent: October 10, 2017Assignee: Ford Global Technologies, LLCInventor: Alvaro Masias

Patent number: 9777932Abstract: A system is provided for heat recovery from shower greywater. An outlet for greywater is connected to a heat exchanger's inlet for greywater and the heat exchanger is designed so that a cold supply water flows in the opposite direction through the heat exchanger relative to the relatively hot greywater, so that heat exchange works under a counterflow principle and heat energy is transferred from the hot greywater to the cold supply water. A manifold having a nozzle outlet for hot supply water is connected to a waste pipe so that the manifold nozzle outlet for hot supply water opens into the waste pipe at a position downstream of the waste pipe inlet for greywater but upstream of the waste pipe outlet for greywater.Type: GrantFiled: February 2, 2016Date of Patent: October 3, 2017Inventors: Henrik Hagman, Gustav Nillson
