20110244778 | HEATING, VENTILATING AND AIR-CONDITIONING APPARATUS - An HVAC system is provided for use in a vehicle having a passenger compartment volume. The HVAC system includes a HVAC housing having a duct opening formed in an exterior sidewall thereof. An evaporator is further provided for exhausting air downstream that is cooler than the air on the upstream side. An auxiliary compartment, such as a storage bin, is spaced apart from the HVAC housing, such as in a remote location of the passenger compartment. An auxiliary duct fluidly interconnects the HVAC housing and the auxiliary compartment via the duct opening for transmitting the cool exhausted air to the auxiliary compartment to provide a cooling effect within the auxiliary location. The auxiliary duct, in some embodiments, is disposed external from the HVAC housing for improved service and retrofitting to existing HVAC systems. | 10-06-2011 |
20120222850 | HEAT EXCHANGER END CAP - A heat exchanger assembly, such as a condenser, may employ a portion of a heat exchanger end tank to define a slot with a second portion of the end tank. The first and second portions define an interior volume of the end tank. A flared end of a side plate may reside within the slot and may have a straight portion having a first width, a first step portion having a second width that is wider than the first width, and a second step portion that has a third width that is wider than the second width. The flared end may have a tab that protrudes from the second step portion and that is symmetrical about a longitudinal axis of the side plate. The end tank may define a second slot where the tab resides when the flared end resides over an entire cross-sectional portion of a volume defined by end tank. | 09-06-2012 |
20140260736 | GEAR WITH IDLE ZONES - The present teachings provide for a door linkage system including a drive side and a driven side. The drive side includes a drive gear and a drive arm. The driven side includes a driven gear configured to mesh with the drive gear and a guide plate in cooperation with the drive arm. The drive side moves the driven side between an open position and a closed position. Proximate to the open and the closed positions, the drive arm moves the driven side. Between the open and the closed positions, the drive gear moves the driven side. | 09-18-2014 |
20140335774 | CONVEX GRID SHAPE TO REDUCE TURBULENCE UNDER ROTARY DOOR - A fresh air and recirculation air switching case using a rotary door, since an introduced air flows along an inner surface of a circumferential wall of the rotary door, a convex grid is formed on an inner surface of the circumferential wall of the rotary door. In this system, the air flow directed toward a suction inlet is prevented from becoming turbulent behind the rotary door and the air flow noise can be suppressed. | 11-13-2014 |
20150099452 | HVAC TEMPERATURE CONTROL BYPASS THROTTLE - The present teachings provide for an HVAC assembly. A first flue can be configured to fluidly couple a first heat exchanger to a mixing flue. A second flue can be configured to fluidly couple a second heat exchanger to the mixing flue. A door can inhibit fluid communication through the second flue when in a first position. The door can inhibit fluid communication through the first flue when in a second position. The door can permit fluid communication through the first and second flues when in a third position. The third flue can be configured to fluidly couple the first heat exchanger to a portion of the second flue downstream of the second heat exchanger and upstream of the mixing flue when the door is in the third position. | 04-09-2015 |
20150111482 | SERVO LOCKING SNAP FEATURE - Disclosed is a vehicle HVAC system that provides for installation, serviceability, or replacement of at least one actuator servo without removal of the HVAC assembly from the vehicle. As due to the tight space limitations, the present invention provides for at least one fastener-less mounting element of the servo assembly to be attached to the HVAC assembly, without the need for additional fasteners which would require additional space to access with a tool. | 04-23-2015 |
20150251516 | HOUSING FOR VEHICULAR HVAC SYSTEM AND DUAL HVAC SYSTEM - A heating, ventilation, and air conditioning (HVAC) system for a vehicle is disposed within a housing. The housing includes a case and a drainage port that drains fluid from the case of the housing. The drainage port has a conduit member that defines an inlet coupled to the case and an outlet. The case and the conduit member define a fluid passage that has a first area adjacent to the inlet and a second area adjacent to the outlet, the second area is smaller than the first area such that a velocity of fluid at the outlet is greater than at the inlet of the conduit member | 09-10-2015 |
