Abstract
Description
- The present invention relates to HVAC systems in vehicles and more particularly to a duct for delivering air from an HVAC case onto a delivery area at a passenger side foot well of an automobile.
- In automotive vehicles, it is common to have a climate control system located within an instrument panel which provides heated or cooled air to occupants through dash panel defrost air outlets, instrument panel venting air outlets and floor directed air outlets. These traditional climate control systems often include a heater core that performs heat exchange between the engine coolant, which is heated by the engine, and the cool air in the cabin/outside environment, in order to provide warm air to the passenger compartment. Some vehicles include an air conditioning system that cooperates with an evaporator for absorbing heat from the air in the vehicle. The heater core and evaporator are typically provided in an HVAC case located in the passenger compartment of the vehicle.
- A vehicle dash panel defines a boundary between an engine compartment and a passenger compartment. There has been an increasing trend to provide increased space within the passenger compartment of the vehicle. To accommodate such demand, automobile manufacturers are revising the layout of instrument panels to increase space. The profiles of instrument panels are becoming lower and decreasing in size. As a result, packaging challenges are created for components cooperating with or contained within the instrument panel.
- One of the major components subject to packaging challenges is the HVAC case and related ducting required to allow the hot and cold air to enter and exit the passenger compartment. The location of respective dash panel defrost air outlets, instrument panel venting air outlets and floor directed air outlets remains a critical factor in HVAC performance and overall passenger comfort. As a result, it is necessary to provide an effective ducting system for delivering heated and cooled air at the desired locations into the passenger compartment while satisfying packaging constraints.
- An HVAC assembly including an HVAC case disposed in a passenger compartment of a vehicle for delivering air at a passenger side foot well includes a duct coupled to an opening on the HVAC case. The duct is configured to deliver air from the HVAC case to the passenger foot well. The passenger foot well is defined by a front boundary, a lower boundary and two side boundaries. The duct includes an input coupled to the opening on the HVAC case and accepting air into an upstream portion having a single passage. The upstream portion directs air in a generally upward direction away from the lower boundary of the passenger side foot well. The duct further includes an intermediate portion whereby the single passage divides into a first and second passage. A first and second outlet is coupled to and downstream of the first and second passage. The first and second outlets dispense air at the passenger side foot well.
- According to other features the first and second passage include a first and second downstream portion connecting the first and second passage at the intermediate portion to the first and second outlet. The first and second passage extend in a first direction at the intermediate portion and extend at a substantially transverse direction at the first and second downstream portion. The intermediate portion includes a planar portion extending between the first and second passage. The planar portion borders the first and second downstream portion at a substantially perpendicular orientation with respect to the first and second downstream portion. The planar portion is adapted to inhibit air flow out of said storage compartment through an upper opening in said storage compartment.
- Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

- With initial reference to
FIG. 1 , a block diagram of a conventional vehicle HVAC system is shown and generally identified atreference 10. A refrigeration cycle R of thevehicle HVAC system 10 includes an air-cooling system 14. The air-cooling system 14 includes acompressor 16 which draws, compresses, and discharges a refrigerant. The power of avehicle engine 20 is transmitted to thecompressor 16 throughpulleys 22 and abelt 24. - As is well known, the
vehicle engine 20 drives not only theair conditioning compressor 16 but also such auxiliaries as a generator, a hydraulic pump for a power steering unit, and a coolant pump via belts and other power transmitting devices. - In the refrigeration cycle R, the
compressor 16 discharges a superheated gas refrigerant of high temperature and high pressure, which flows into acondenser 28. Here, heat exchange is performed with the outside air sent by a cooling fan (not shown), so that the refrigerant is cooled for condensation. The refrigerant condensed in thiscondenser 28 then flows into areceiver 30, in which the refrigerant is separated into a gas and a liquid. A redundant liquid refrigerant in the refrigeration cycle R is stored inside thereceiver 30. - The liquid refrigerant from the
receiver 30 is decompressed by anexpansion valve 34 into a gas-liquid double phase state of low pressure refrigerant. The low pressure refrigerant from theexpansion valve 34 flows into anevaporator 36 by way of aninlet pipe 38. Theevaporator 36 is arranged inside anHVAC case 42 of the vehicleair conditioning system 14. The low pressure refrigerant flowing into theevaporator 36 absorbs heat from the air inside theHVAC case 42 for evaporation. Anoutlet pipe 40 of theevaporator 36 is connected to the suction side of thecompressor 16, so that the cycle components mentioned above constitute a closed circuit. - The
HVAC case 42 forms a ventilation duct through which air conditioning air is sent into the passenger compartment. TheHVAC case 42 contains afan 44 which is arranged on the upstream side of theevaporator 36. An inside/outside air switch box (not shown) is arranged on the suction side of the fan 44 (the left side inFIG. 1 ). The air inside the passenger compartment (inside air) or the air outside the passenger compartment (outside air) switched and introduced through the inside/outside air switch box is sent into theHVAC case 42 by thefan 44. - The
HVAC case 42 accommodates, on the downstream side of theevaporator 36, a hot water heater core (heat exchanger) 46. Theheater core 46 includes aninlet pipe 48 and anoutlet pipe 50. Hot water (coolant) of thevehicle engine 20 is directed to theheater core 46 through theinlet pipe 48 by awater pump 52. Awater valve 54 controls the flow volume of engine coolant supplied to theheater core 46. Aradiator 56 and athermistor 58 further cooperate to control the temperature of the coolant. - A
bypass channel 60 is formed beside the hotwater heater core 46. Anair mix door 62 is provided to adjust the volume ratio between warm air and cool air that passes through the hotwater heater core 46 and thebypass channel 60, respectively. Theair mix door 62 adjusts the temperature of the air blown into the passenger compartment by adjusting the volume ratio between the warm air and cool air. - Additionally, a
face outlet 64, afoot outlet 68, and adefroster outlet 70 are formed at the downstream end of theHVAC case 42. Theface outlet 64 directs air toward the upper body portions of passengers, thefoot outlet 68 directs air toward the feet of the passengers, and thedefroster outlet 70 directs air toward the internal surface of a windshield. Theoutlets air mix door 62 and the outlet mode doors mentioned above are driven by such electric driving devices such as servo motors via linkages or the like. - Turning now to
FIGS. 2 and 3 , a passenger foot duct according to the present teachings is shown and generally identified atreference 70. Thepassenger foot duct 70 is coupled to theHVAC case 42 in the passenger compartment of the vehicle at attachment points 72 and configured to deliver air from theHVAC case 42 onto the feet of an occupant in the passenger seat of the vehicle. As will be described in greater detail, thepassenger foot duct 70 is adapted to route from an opening 76 (FIG. 3 ) in theHVAC case 42, around and above astorage compartment 74 disposed adjacent to theHVAC case 42, and to a first and second outlet aimed at a delivery area or foot well 78 onto the feet of a passenger. The foot well 78 is generally defined by afront boundary 79, a first andsecond side boundary lower boundary 82. - The
opening 76 in theHVAC case 42 is one of a plurality ofopenings 83 arranged on theHVAC case 42 for delivering air to other delivery destinations associated with theface outlet 64, thefoot outlet 68 and thedefroster outlet 70. In general theopenings HVAC case 42 at an intermediate position between a passenger side compartment 84 and adriver side compartment 86 of the vehicle. - With continued reference to
FIG. 2 and further reference toFIGS. 3-5 , the orientation of thepassenger foot duct 70 will be described in greater detail. Thepassenger foot duct 70 is coupled at aninput 88 to theopening 76 in theHVAC case 42 and directs air through anupstream portion 92 generally upward away from the floor of the vehicle (FIG. 2 ) and forward into the passenger compartment of the vehicle (FIG. 3 ). Thepassenger foot duct 70 is then routed to an area above thestorage compartment 74 and astorage compartment door 94. As will be described further, anintermediate portion 100 of thepassenger foot duct 70 is arranged to cover a portion of anupper opening 102 in thestorage compartment 74 to impede air flowing from thestorage compartment 74 into ablower fan 108 disposed above thestorage compartment 74. As a result, contents in thestorage compartment 74 are less likely to be ingested into theblower fan 108. - The
intermediate portion 100 directs air toward the front of the vehicle to a downstream portion 110 (FIGS. 4 and 5 ). Thedownstream portion 110 directs air downward toward the floor of the vehicle and out a first andsecond outlet - With particular reference to
FIGS. 6-10 , thepassenger foot duct 70 will be further described. Theinput 88 delivers air through theupstream portion 92 defining asingle passage 120. Thesingle passage 120 directs air from theupstream portion 92 into theintermediate portion 100. Theintermediate portion 100 divides thesingle passage 120 into a first andsecond passage single passage 120 into the first andsecond passage single passage 120 into a first andsecond passage foot well 78. - At the
intermediate portion 100 and extending between the first andsecond passage flange 130. The structure of theflange 130 and the first andsecond passage FIG. 8 ) to inhibit air flow from thestorage container 74 and into the blower fan 108 (FIG. 3 ). Theupper boundary 132 also reduces noise generated by theblower fan 108 from entering the passenger compartment through thestorage compartment 74. It is appreciated that an additional seal such as foam may be added between anupper wall 136 of thestorage container 74 and/or theupper boundary 132 of theintermediate portion 100 for further diminishing noise transmission into the passenger compartment. - From the first and
second passage intermediate portion 100, air is directed into a respective first and seconddownstream passage downstream passage passenger foot duct 70 at the first andsecond outlets - With particular reference now to
FIG. 10 , the directional orientation of thepassenger foot duct 70 will be described. Theupstream portion 92 directs air in a first direction A generally upward and away from the foot well 78 and the first andsecond outlet passenger foot duct 70. Air then transitions into theintermediate portion 100 and flows in a second direction B. From theintermediate portion 100, air then transitions into thedownstream portion 110 and flows in a third direction C. The third direction C is generally transverse to the second direction B. - Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, the specification and the following claims.
