FIELD: transport engineering. ^ SUBSTANCE: invention relates to ventilation, heating and provision of comfortable conditions for driver and passengers in cars. Proposed device arranged in instrument panel contains heater connected with inlet hole to deliver air into guide channel of device distributing air between nozzles for blowing side window glasses and windshield of automobile. Novelty is that device contains air pressure distributing chamber with section decreasing from maximum value in center of blowing zone to minimum value at edges of zone and communicating with guide channel of constant section over entire length of windshield blowing zone and containing channels formed by ribs to direct air for blowing side window glasses. ^ EFFECT: provision of uniform distribution of air flow as to velocity and volume, improved efficiency of blowing zones of visibility, prevention of misting and freezing of windshield and side window glasses of automobile. ^ 6 dwg |
