Air supply channel for connecting air conditioning unit e.g. heater, with air vent of e.g. motor vehicle, has air guiding unit to partially divert main flow flowing through channel, such that rotational flow is developed in channel

摘要

The channel (1) has an air guiding unit (3) to partially divert a main flow flowing through the supply channel in such a manner that a rotational flow (D) is developed in the supply channel. The air guiding unit is arranged in an area of an end of the supply channel that is connected with an air conditioning unit (2). An adjacent channel is diverted from the supply channel in an area of the guiding unit and leads back an auxiliary flow tangential to the main flow and a direction component perpendicular to the main flow into the supply channel.
