Abstract: A heating ventilation and cooling (HVAC) system includes: a fan blower; and a cross-flow heat exchanger in fluid communication with the fan blower. The cross-flow heat exchanger includes a first set of conduits which define a first communication path, a second set of conduits which define a second communication path and a thermoelectric device therebetween.

Abstract: A vehicle HVAC system includes a HVAC components such as a duct, vent, manually adjustable airflow control head, toggle or housing manufactured from a molded plastic material having an antimicrobial additive. The antimicrobial additive is preferably introduced as an additive during molding of the HVAC components that are typically injection or blow molded parts. Usage of a plastic having an antimicrobial additive continuously fights the growth of microbes such as most common bacteria, yeasts, molds and fungi that cause stains, odors and product degradation that can cause stains, odors and product degradation. The antimicrobial additive becomes an integral part of the HVAC components and therefore is maintenance free.

Abstract: Induction heating is utilized to braze together a plurality of components for a heat exchanger. The induction heater is provided with flux concentrators that raise the applied temperature at locations on the heat exchanger components which require a higher temperature. In this manner, a relatively small inductor heater can replace the relatively massive furnaces of the prior art.

Abstract: A door for use in a vehicle HVAC system is formed to have a portion preferably formed of a magnesium alloy. In one embodiment, the magnesium alloy forms a sub-frame, and a plastic is placed over said sub-frame.

Abstract: An electric motor having a snap-together construction without the use of separate fasteners. The construction of the motor removes additive tolerances for a more accurate assembly. The motor is capable of programming and testing after final assembly and can be non-destructively disassembled for repair or modification. The motor is constructed to inhibit the ready entry of water into the motor housing and to limit the effect of any water which manages to enter the housing.

Abstract: A stator device for an axial flow fan has a plurality of first stator elements and a corresponding plurality of second stator elements, the first stator elements being disposed axially rearwardly of the second stator elements so as to define an air flow slot therebetween.

Abstract: A heat exchanger comprises a bundle of tubes connected between two water boxes, each of the latter being delimited by a wall of moulded plastics material having two opposed, lateral faces on which are secured lateral portions of two mountings which join the two water boxes together and which enclose the tube bundle between them. Each water box is secured to each mounting by means of at least one self-tapping screw which passes through an aperture formed in a lateral portion of the mounting and which engages in a bore formed in the wall of the water box.
