Patent number: 9920828Abstract: A system for regulating lubricant temperature within a vehicle axle is provided. A differential housing has a primary chamber that contains the differential, and a secondary chamber separated from the primary chamber. A sump is in the primary chamber for collecting lubricant. An inlet to the secondary chamber allows the lubricant to flow from the primary chamber into the secondary chamber. An outlet to the secondary chamber allows the lubricant stored therein to be purged into the sump. When the lubricant is below a certain threshold temperature, a temperature-responsive valve is configured to close to inhibit the fluid to travel through the outlet. When the temperature of the lubricant rises to exceed the threshold, the valve is configured to open and permit the fluid to travel through the outlet.Type: GrantFiled: June 27, 2016Date of Patent: March 20, 2018Assignee: Ford Global Technologies, LLCInventors: Mathew John Fast, Sunil Katragadda, Danrich Henry Demitroff, W.

In one example, a three-way split conduit may include one fluid inlet conduit splitting into two outlet conduits with an included angle of less than 90 degrees between the two splitting outlet conduits. A movable rotary ring coupled to the three-way split conduit may be rotated by an actuator to open or block the three way split conduits, regulating the fluid flow passages along the three-way valve assembly.Type: GrantFiled: November 10, 2015Date of Patent: March 20, 2018Assignee: Ford Global Technologies, LLCInventors: Danrich Henry Demitroff, Cary Cole, Sunil Katragadda, Lawrence Marshall, Furqan Shaikh Zafar

Patent number: 9856779Abstract: Methods and systems are provided for a phase change material (PCM) integrated radiator. In one example, a method may include adjusting a radiator control valve into a first position to flow coolant only through a first zone of a radiator containing phase change material (PCM) and not through a second zone of the radiator not containing phase change material. The method may further include adjusting the radiator control valve into a second position to flow coolant only through the second zone of the radiator and not the first zone.Type: GrantFiled: April 2, 2015Date of Patent: January 2, 2018Assignee: Ford Global Technologies, LLCInventors: Sunil Katragadda, Cary Cole, Michael Levin, Danrich Henry Demitroff, Mathew John Fast, Furqan Zafar Shaikh

Patent number: 9789746Abstract: An air-conditioning system which may be included in a motor vehicle may include a single pair of tube-and-plate heat exchangers arranged within a common vacuum enclosure, the heat exchangers selectively coupled with a heat source, a radiator, and an air-conditioning core. During an adsorbing/evaporating mode, coolant may circulate between a first heat exchanger and the radiator and vapor may evaporate from the surface of non-adsorbent-coated plates of the second heat exchanger and be adsorbed at adsorbent-coated plates of the first heat exchanger while coolant circulates between the second heat exchanger and the core. During a desorbing/condensing mode, coolant may circulate between a heat source and the first heat exchanger to effect desorption of vapor from the adsorbent in the first heat exchanger, while melting PCM in the core exchanges heat with air blown through the core to provide cooling.Type: GrantFiled: March 25, 2014Date of Patent: October 17, 2017Assignee: Ford Global Technologies, LLCInventors: Michael Levin, Furqan Zafar Shaikh, Danrich Henry Demitroff, Lawrence Marshall

Patent number: 9610825Abstract: A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine.Type: GrantFiled: April 6, 2015Date of Patent: April 4, 2017Assignee: Ford Global Technologies, LLCInventors: Yongfang Zhong, Michael Levin, Furqan Zafar Shaikh, Danrich Henry Demitroff, Donald Masch
