A heating and ventilation unit for a motor vehicle comprises a mixing chamber containing a heat exchanger and disposed within the vehicle interior. Pipe connections extending from the heat exchanger pass through the rear wall of the mixing chamber. An aperture in a wall of the mixing chamber is provided for enabling the heat exchanger to be withdrawn from the mixing chamber into the vehicle interior. The aperture is formed in a side wall of the chamber and is dimensioned to permit passage of the heat exchanger as well as the rearwardly projecting connections. A closure and support element is provided which is insertable through the aperture and which, when inserted, serves to support the heat exchanger within the chamber and prevent forward displacement of the exchanger away from the rear wall of the mixing chamber.

Heating and ventilation system for vehicles

An evaporator is fabricated from metal pipes bundled together by cooling fins. The pipes have their ends embedded in a curable plastic securing them to a plastic collecting box. The collecting box has a distributing section with a plurality of injection orifices and return orifices flowing respectively into injection chambers and return flow chambers. The injection chambers merge into an injection collecting chamber and the return flow chambers merge into a return collecting chamber. A plastic connecting section has an integral injection pipe and return pipe and is connected to the distributor pipe by a tongue and groove connection sealably secured together by a curable plastic. The injection pipe and return flow pipe are in fluid communication with the injection collecting chamber and return collecting chamber respectively.
