20080200110 | Box vane mixing element for automotive heating, ventilating and air conditioning system - An HVAC housing assembly includes a novel structure to aid the mixing of hot and cold air downstream of the evaporator and heater core. One or more variable nozzles are carried for displacement with the temperature door for accelerating some of the cold air stream through an internal housing opening and varying the cold air stream impingement angle with the hot air stream at their point of confluence to establish secondary mixing sites and substantially improving the resulting heat transfer coefficient. | 08-21-2008 |
20080318118 | Metering schemes for reducing thermal spread in a battery pack - A battery pack assembly comprising a plurality of battery packs each including a plurality of cells and at least one metering plate for metering the quantity of air flowing respectively through each of the air paths of the battery packs. An inlet metering plate is disposed upstream of the battery packs to meter the uneven flow of cooling air generated by the inlet manifold. The inlet metering plate utilizes a plurality of apertures, which can vary in size and shape, to produce equal streams of cooling air to cool all the battery packs to a substantially uniform temperature. An outlet metering plate can be disposed downstream of the battery packs to meter the flow of outgoing cooling air through the channels of the upper cylindrical sections to produce equal air flow around all of the cells in a stack to cool all of the cells to a substantially uniform temperature. | 12-25-2008 |
20100035139 | Low thermal spread battery module - A battery pack assembly including a plurality of cells surrounded by a spacer for creating a radial space between the cell and cylindrical sections defining a casing. At least two of the cylindrical sections are conical or in different radial positions to define differing volumes between the respective two cells. Each of the cylindrical sections may be eccentrically offset from the respective cell to define a greater radial space adjacent the air inlet chamber and a lesser radial space adjacent the respective exit to increase the velocity of the discharging air adjacent the respective exit. Each of the cylindrical sections may have a casing undulating surface extending circumferentially and/or each of the walls of the cells may have a similar cell undulating surface to increase the cooling capacity of the cooling air. | 02-11-2010 |
20110111278 | LOW THERMAL SPREAD BATTERY MODULE - A battery pack assembly having a casing enclosing stacks of cells. The casing defines a plurality of air intake chambers for receiving a flow of air and a plurality of slots diametrically opposite of the air intake chambers for dispensing the flow of air, and the air flows circumferentially through a gap around the cell walls to cool the cells. A plurality of circumferentially and radially spaced flow interrupters are disposed on at lest one of the cell wall and the casing for disrupting the flow of air to increase the heat transfer coefficient of that air. | 05-12-2011 |
20110139414 | Low Pressure Drop Fin with Selective Micro Surface Enhancement - The assembly includes a heat exchanger assembly including a plurality of tubes extending between first and second manifolds. A plurality of fins extend back and forth between and long the tubes in a continuous patch and define a plurality of legs extending between the tubes. Each of the legs includes a plurality of front long louvers for conveying a stream of air through the legs. Each of the legs further defines a plurality of main spoilers between the front long louvers and the back edges of the legs for inducing turbulence in the stream of air with each of the main spoilers having a spoiler height in the range of 50 to 90 percent of the long louver height and each of the main spoilers having a spoiler length in the range of 10 to 35 percent of the long louver length. | 06-16-2011 |
20120276831 | System and Method of Providing Quick Thermal Comfort with Reduced Energy by Using Directed Spot Conditioning - A heating, ventilation, and air conditioning (HVAC) system and a method of controlling a HVAC system that is configured to provide a perceived comfortable ambient environment to an occupant seated in a vehicle cabin. The system includes a nozzle configured to direct an air stream from the HVAC system to the location of a thermally sensitive portion of the body of the occupant. The system also includes a controller configured to determine an air stream temperature and an air stream flow rate necessary to establish the desired heat supply rate for the sensitive portion and provide a comfortable thermal environment by thermally isolating the occupant from the ambient vehicle cabin temperature. The system may include a sensor to determine the location of the sensitive portion. The nozzle may include a thermoelectric device to heat or cool the air stream. | 11-01-2012 |
20140096945 | HEATING AND COOLING SYSTEM FOR OCCUPANTS OF THE REAR PORTION OF A VEHICLE - A heating, ventilation, and air conditioning (HVAC) system configured for use in a vehicle to provide a perceived comfortable thermal environment to an occupant seated in a rear portion of a vehicle cabin. A heat exchanger provides a first airstream characterized as having a first temperature to an air moving device configured to generate a second airstream characterized as having a second temperature. The second airstream comprises a mixture of the first airstream and cabin air drawn from the rear portion of the vehicle cabin. The air moving device may be disposed in the rear portion of the vehicle. The HVAC system further includes a nozzle that may be configured to direct the second airstream toward an occupant in the rear portion of the vehicle cabin to provide spot conditioning. | 04-10-2014 |
20140271166 | LOW POWER AND LOW NOISE FAN-SCROLL WITH MULTIPLE SPLIT INCOMING AIR-STREAMS - The disclosure relates to a blower assembly having a blower housing, an impeller adapted for rotation about an axis A-A disposed in blower housing, and an intake plenum cooperating with the interior first surface of the blower housing to define an air entrance passage for receiving an incoming air flow. The intake plenum includes means to split the incoming air flow into a plurality of air streams and direct the air streams to predetermined portions of the impeller susceptible to stall conditions as the impeller rotates about the axis A-A. The means to split the incoming air may include a splitter plate disposed in the air entrance passage or at least one port defined in a portion of the air intake plenum adjacent the impeller. | 09-18-2014 |
