Abstract
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.
