Abstract
A ventilation unit for heating or air-conditioning in a motor vehicle. The unit includes a blower and a heat exchanger, with a diffuser positioned in the flow of air from the blower. The diffuser spreads the air flow so that it substantially covers the heat exchanger area. A grid positioned between the diffuser and the heat exchanger aids in spreading the flow of air to the peripheral portions of the heat exchanger.
