International Classification:

H04M 342

US Classification:

379 68, 379 8825, 37920701

Abstract:

International Classification:

US Classification:

622283, 622281, 123 4144, 123 4119, 417279, 417366

Abstract:

A novel pump pressure limiting method for preventing coolant in a cooling system from reaching pressures that exceed predetermined system coolant pressure limits. The method includes reducing the system coolant pressure, as needed to prevent system over-pressurization, by reducing the operational speed of a coolant pump used to pump the coolant through the system. In one embodiment, the system coolant pressure is determined directly, by measurement of the pressure of the coolant in the system typically using pressure sensors. The operational speed of the coolant pump is then reduced until the system coolant pressure decreases to within the predetermined pressure limits. In another embodiment, the system pressure is determined indirectly, by obtaining pressure-indicating data such as coolant temperature. The coolant system pressure is then correlated with the coolant temperature or other data and then the operational speed of the coolant pump is reduced accordingly.

Filed:

Jan 11, 2006

Appl. No.:

11/306787

Inventors:

William Schwartz - Pleasant Ridge MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

F01P 7/02
F01P 7/10

US Classification:

123 4104, 123 4111, 123 4149

Abstract:

A cooling system for an internal combustion engine mounted within a vehicle includes a radiator for rejecting heat to ambient air and an axial fan mounted within a fan shroud associated with a radiator. The fan has a stationary hub equipped with louvers which may be controlled so as to either block off or allow airflow through the hub, and consequentially through the radiator. In this manner, the airflow past the fan may be greatly increased when the vehicle is operated at a higher groundspeed, while decreasing the amount of power consumed by the fan.

Abstract:

A flush and fill process is used to ready a fuel cell cooling circuit for initial use. An external flushing system releasably connected to the cooling circuit circulates flushing coolant through the cooling circuit to remove contaminants from the wetted surfaces of the cooling circuit before the fuel cell is put into use. The flushing system includes a pump for circulating the flushing coolant through the cooling circuit, filters for removing contaminants from the coolant and a heater for elevating the temperature of the coolant. Following the flushing process to remove contaminants, the flushing system is disconnected from the cooling circuit and the cooling circuit is filled with fresh coolant.

237 123R, 237 5, 237 123 B, 123 411

Abstract:

A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

US Classification:

73 2902

Abstract:

A humidity sensing device for determining the amount of humidity in at least one primary fluid stream that is passed to a fuel cell stack is provided. The sensing device includes an outer housing and an inner housing. The outer housing is positioned within at least one conduit such that the outer housing and the conduit coact with each other to generate at least one secondary fluid stream from the primary fluid stream. The inner housing is positioned within the outer housing such that the inner housing is configured to receive the secondary fluid stream and to measure an amount of water present in the secondary fluid stream to determine the amount of humidity in the primary fluid stream.
