Abstract: An evaporator for dissipating heat from a heating, ventilation and air conditioning (HVAC) system has a first side plate and a second side plate. The second side plate is spaced apart and parallel to the first side plate. An electronic circuit for controlling the HVAC system is printed on the first side plate.

Abstract: An automotive heat, ventilation and air conditioning (HVAC) system includes an electrical control module for controlling the motor of the system. The module includes a connector base supporting a circuit board having spaced side edges extending into the housing. The invention is distinguished by the circuit board having a first leg extending from the base and through a curved section and into a second leg to a distal end spaced from the base with an electrical circuit extending over the exterior of the first leg and over the curved section and over the second leg. The circuit board includes an offset section between the base and the first leg for centralizing the legs on the base.

Abstract: The invention provides an isolator for isolating vibration associated with an electric motor. The isolator includes a first body portion operable to be positioned adjacent to an external surface of a motor case of the electric motor. The isolator also includes a tongue integrally formed with and narrower than the first body portion. The tongue is operable to be received in a groove formed in the motor case. The isolator also includes a second body portion integrally formed with and wider than the tongue. The second body portion is operable to be disposed adjacent an internal surface of the motor case. As a result, at least a portion of the motor case of the electric motor is disposed between the first and second body portions.

Abstract: A heating and air-conditioning (HVAC) module for an automotive vehicle wherein the electric motor for the blower includes a double walled motor housing for noise abatement. The housing defines a cup-shaped inner casing with an open end and a closed end. An outer casing surrounds and is integrally connected to the inner casing by an integral flange. The outer casing extends upwardly from the flange to a rim to define a space surrounding the inner casing. An end cap includes a groove to engage the rim and extends over and in spaced relationship to the closed end of the inner casing. The end cap is held in place by fasteners threadedly engaging posts extending upwardly from the flange, with one of the posts extending upwardly from a female electrical connector that extends radially between the outer casing and the inner casing for supplying electrical power to the motor.

Abstract: A multi-function condenser for an air conditioning system includes a first header, a second header, a plurality of tubes, and a conduit. The tubes extend in parallel relationship between the headers for establishing fluid communication between the first header and the second header. The second header includes a header portion and a receiver portion. A conduit extends into and out of and is surrounded by the receiver portion to define a space between the conduit and the receiver portion. Heat is transferred between hot refrigerant flowing in the receiver portion, the header portion, and cooler refrigerant flowing through the conduit as the refrigerant flows through the conduit independently of the refrigerant flowing in the space and in the header portion to increase an overall efficiency of the air conditioning system.

Abstract: A casing for a HVAC system in an automobile for moving air comprises a plurality of sections, each of which is molded of plastic material. The sections of the casing are connected and sealed to one another at a plurality of joints. The improvement resides in the tongue having a slot extending into the distal end thereof for splitting the tongue into first and second forks in frictional engagement with the side-walls of the groove. The forks are compressed together by the groove to narrow the slot from top to bottom to retain the tongue in the groove and to seal the sections together.
