Filed:

Jan 10, 2003

Appl. No.:

10/340053

Inventors:

Thomas Martin Urbank - Lockport NY
Aaron P. Running - Rochester Hills MI
Karma Vir Sangwan - East Amherst NY

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B60H 132

US Classification:

62133, 236 51

Abstract:

A manually controlled motor vehicle HVAC system is activated for automatically pre-heating or pre-cooling the cabin following remote starting of the vehicle engine. When the engine has been remotely started, an HVAC controller estimates initial outside air and cabin air temperatures, and determines if pre-heating or pre-cooling is appropriate based on the estimated initial temperatures, the engine coolant temperature and a measure of the engine soak time. When pre-heating or pre-cooling is deemed to be appropriate, the HVAC parameters normally set by a driver interface panel are selectively overridden based on the estimated initial outside air and cabin air temperatures. In a particularly advantageous embodiment, the initial outside air temperature is estimated based on an inlet air temperature sensor of the engine or on a refrigerant pressure sensor of the HVAC system prior to activation of the refrigerant compressor.

Abstract:

A shroud for a vehicle engine cooling fan mounted to a generally rectangular radiator that has fixed air guide vanes in strategic areas of the shroud outside of the periphery of the fan blades to direct and channel streams of peripheral air flowing through the corners of the radiator into these areas inward and in a swirling pattern into the fan blades and more particularly in a generally smooth and circuitous path counter to the direction of rotation of the fan and directly onto the pumping surfaces of the fan blades. This effectively feeds additional air into the fan and preloads the blades so that air pumping efficiency is resultantly improved and more air is moved through the radiator for improved heat exchange.
