With this, an air flow W4 prevented from flowing to a vehicle compartment space 12 by the air deflector 20 is introduced to the top end of the air suction part 36 and flows into the interior of the air suction part 36. In this manner, the air flow W4 flowing at a speed corresponding to the running speed of a vehicle 10 flows into the interior of the air suction part 36, so that even though the air flow W4 is the outside air, the air flow W4 can effectively air-cool a battery 34 installed in a battery housing part 32.Type: ApplicationFiled: September 5, 2007Publication date: August 5, 2010Inventor: Atsuki Nemoto

Patent number: 7766078Abstract: An automotive vehicle air conditioning system has air introduced into an air conditioning case. The introduced air is always discharged to both sides of a passenger compartment regardless of the air conditioner mode while the air conditioning system maintains the amount of air discharged through defrost openings in a defrost mode. Air leakage between both sides of a mode door and the air conditioning case is effectively prevented by a cover carried by the mode door without additional sealing to improve air conditioning performance.Type: GrantFiled: January 9, 2004Date of Patent: August 3, 2010Assignee: Halla Climate Control Corp.Inventors: Jong-Su Kim, Dae-Woong Lee

Publication number: 20100155015Abstract: A HVAC assembly includes a temperature mixing valve that comprises a shaft, an upper paddle, a lower paddle, and a yielding means. The upper paddle and the lower paddle attach to the shaft. The yielding means applies a force to keep the upper paddle sealed to prevent cold air in a cold air inlet from entering a mixing zone and the lower paddle moves away from a shared sealing boundary over a predetermined angle of rotation before the upper paddle initially moves to allow cold air to enter the mixing zone. Movement of the lower paddle away from the shared sealing boundary allows cold air to enter a hot air inlet and admix with hot air to mix in the mixing zone to produce non-stratified air.Type: ApplicationFiled: December 18, 2008Publication date: June 24, 2010Applicant: Delphi Technologies, Inc.Inventor: Garrett Wade Hoehn

Patent number: 7730734Abstract: A cooling apparatus of a fuel cell vehicle in which a cooling efficiency of a fuel cell cooling heat exchanger located downstream of an air conditioner external heat exchanger does not decrease. (1) In the cooling apparatus, the air conditioner external heat exchanger and the fuel cell cooling heat exchanger are partially offset from each other so that a high-temperature portion of the air conditioner external heat exchanger is not overlapped with the fuel cell cooling heat exchanger in a front view taken from a front side of the vehicle. (2) A portion of the fuel cell cooling heat exchanger extending beyond an end of the air conditioner exterior heat exchanger opposite the high-temperature portion is disposed outside a fan shroud so as to be cooled by a vehicle-running wind only.Type: GrantFiled: January 24, 2006Date of Patent: June 8, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Jun Hoshi, Susumu Ichikawa

Patent number: 7726142Abstract: There is a need for a compact and high capacity HVAC system for a vehicle cab. This need is met by a roof enclosed HVAC system. The system includes a roof upper panel, a roof lower panel, a fresh air duct communicated with a fresh air inlet exposed to an exterior of the cab, a recirculation air duct communicated with a recirculation air inlet exposed to an interior of the cab, and a conditioned air duct communicated with an air outlet exposed to the interior of the cab. An HVAC unit is mounted between the roof upper and lower panels. The HVAC unit includes a fan unit, a heater unit and an evaporator unit. The heater and evaporator units are concentrically arranged around and surrounding the fan unit.Type: GrantFiled: September 8, 2006Date of Patent: June 1, 2010Assignee: Deere & CompanyInventor: Eric Albert Keen
