A holder for an interior trim part, in particular for covering the passenger compartment of a motor vehicle, has at least one supply line for guiding a temperature-controllable, liquid or gaseous fluid, to an outlet via which the fluid can emerge from the supply line, and an inlet via which the fluid can enter a discharge line. An interior trim part can be arranged on the holder in such a manner that the outlet of the holder is fluidically connected to an inlet of the interior trim part, and the inlet of the discharge line of the holder is fluidically connected to an outlet of the interior trim part.

HVAC MODULE

An HVAC module for a vehicle includes a housing having a plurality of airflow paths to guide the air that passes through a cooling unit or a heating unit. An upper discharge outlet temperature is indeterminate based on a temperature of a single temperature sensor in one of the plurality of airflow paths and a blend setting. The HVAC module includes a temperature sensor to determine a reference temperature of the air at a sensor location. The reference temperature is offset from a floor outlet temperature by a floor offset function of the blend setting. The reference temperature is offset from the upper discharge outlet temperature by an upper offset function of the blend setting.

DEFROST DUCT WITH ACOUSTIC MATERIAL INSERTS

A defrost duct assembly for a vehicle includes a housing having a wall that defines an air passage. The air passage extends between an inlet and an outlet of the housing. The wall includes an opening into the air passage. A noise attenuation panel is attached to the housing, and covers the opening in the housing. The noise attenuation panel is an acoustic material that is operable to attenuate noise from within the passage of the housing, while maintaining sufficient air flow to adequately defrost a front windshield of the vehicle. The housing may include multiple outlets and multiple openings covered by one or more noise attenuation panels. The noise attenuation panel is preformed to mate with the housing, and minimize disturbance to the flow of air within the passage.

The base has foam cells having an average diameter of 20 μm to 50 μm are distributed on thereon.

VEHICLE AIR CONDITIONING DEVICE

A vehicle air conditioning device (10; 10A; 10B) has a casing (20) configuring a temperature adjustment section (12; 12A; 12B). The casing (20) has provided in a position thereof opposed to an inflow surface (41) of a heat exchanger (40) a flow direction change section (30) which causes the flow direction of air led to the temperature adjustment section (12; 12A; 12B) from a duct section (13; 13A; 13B) to bend approximately 90 degrees and leads the air to the inflow surface (41). Guide portions (60, 70; 60A, 70A; 60B) smaller in area than the flow direction change section (30) as seen when directly facing the inflow surface (41) are provided in a heat exchanger upstream space (22) between the inner wall surface of the casing (20) and the inflow surface (41).

An air conditioning device for a vehicle has an air-conditioning case, a heater core, a first air mix door, a second air mix door, and an actuator. The air-conditioning case therein has a first air passage and a second air passage. The first air mix door and the second air mix door are arranged in the first air passage and the second air passage respectively, and adjust a ratio between a flow rate of air passing through the heater core and a flow rate of air bypassing the heater core by an opening/closing operation. The actuator interlocks the opening/closing operations of the first air mix door and the second air mix door such that opening degrees of the first air mix door and the second air mix door are different from each other.

Method of Making an Acoustic Automotive HVAC and AIS Duct with a Particle Fiber Slurry

Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such products so as to allow large scale implementation.

AIRFLOW OUTLET

An airflow outlet is provided. The airflow outlet comprises at least a first housing, a second housing, a first shut-off door, a second shut-off door, and a control apparatus. The first housing defines an outlet opening and the second housing defines an inlet opening. The first housing and the second housing are operatively coupled and define a substantially closed airflow path between the inlet opening and the outlet opening. The first shut-off door is coupled to the second housing and rotatable about a first axis. The second shut-off door is coupled to the second housing and rotatable about a second axis. The first shut-off door and the second shut-off door are operatively configured to meter a flow of air through the inlet opening by occupying a selectable operating position. The control apparatus is configured to control the selectable operating position of the first shut-off door and the second shut-off door.
