AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES

摘要

PURPOSE: An air conditioning device for a vehicle is provided to enable hot air blowing to an air mixing area to have uniform air distribution and pressure distribution regardless of position. CONSTITUTION: An air conditioning device for a vehicle comprises a cold-air path(14), a hot-air path(16), an air mixing area(A), and a stepped unit(22). Cold air emitted from a vaporizer(12a) flows in the cold-air path. Hot air emitted from a heater core(16a) flows in the hot-air path. The air mixing area mixes cold air emitted from the cold-air path with hot air emitted from the hot-air path. For the hot air emitted from the heater core to be able to be guided to the air mixing area, the hot-air path comprises a hot-air guide wall(18), which is extended from the lower part of the heater core toward the air mixing area.
