The invention relates to heating and/or air conditioning apparatus for the cabin of a motor vehicle, of a kind in which two separate fans deliver air into a common housing through which the air is passed to a heat exchanger. The object of the invention is to obtain even distribution of the air delivered through the heat exchanger, despite any differences in the flow rates of air delivered by one fan as compared with the other. The apparatus includes a housing having two inlet sections which are arranged facing each other and which are connected to the two respective fans for introducing the two air streams into the housing in parallel and opposed inlet directions. These directions are parallel to a base wall of the housing, and this base wall is provided with a separating bulkhead which projects from it into the interior of the housing. The bulkhead extends in a direction close to the inlet direction, which is substantially diagonal so as to define two chambers within the housing and extending over substantially the same width in the inlet direction. The two chambers exhaust into an outlet section which leads to the heat exchanger.

Heating and/or air conditioning apparatus for a motor vehicle, having

A heating and/or air conditioning installation for a motor vehicle is of the kind having two air blower units, each supplied with air through a respective air admission housing, and each having a volute casing arranged to deliver air into a common distribution housing. The air blower unit comprises a connection member having an input edge which is adapted to be fitted to the outlet aperture of the air admission housing in either one of two different positions; and a casing having a lateral wall defining a volute chamber within the casing. The latter also has a delivery or outlet orifice, and two opposed abutment surfaces, either of which can be fitted to an output edge of the connection member, so as to give two different mounting positions. The blower unit further includes a motor support member having a further abutment edge which is adapted to fit to whichever one of the abutment edges of the casing is not fitted to the connection member; and a motorized blower comprising a motor secured to the motor support member and carrying a blower rotor which rotates within the casing.

Air blower unit for a motor vehicle heating and/or air conditioning

The air blower unit includes a casing having a lower wall, and upper wall and two opposed side walls, which together define two open and opposed end faces of the same profile. The casing also includes a mounting frame, together with an air blower which is mounted within the casing and which comprises a blower rotor, a drive motor for the blower rotor, and two symmetrical half shells which are mated together to define a volute chamber in which the blower rotor and the motor are mounted. This unit is readily adaptable to two different configurations, according to whether the vehicle in which it is to be installed is of the left hand drive or right hand drive type.
