Abstract: Provided is a vehicle air conditioning device including an air conditioning unit in which: a unit case (10) of the air conditioning unit is formed of a plurality of lower and upper divided cases (23, 24, 25); and the divided cases (23, 24, 25) are coupled integrally to each other through a mating portion (34) provided to division end surfaces (30A, 30B, 32). The vehicle air conditioning device also includes a space. (35) having a given height in the top-bottom direction and a given width is formed between respective case inner division end surfaces (32, 30B) of the divided cases (24, 25) on one side and the divided case (23) on the other side, the divided cases (23, 24, 25) constituting the mating portion (34).

Abstract: An object is to provide an aspirator capable of increasing the amount of aspirated secondary air and improving performance and to provide a vehicle air conditioner using the same. The aspirator includes a nozzle 15 that aspirates secondary air; a main body 17 that forms a scroll-shaped airflow path 16 on the outer circumference of the nozzle 15; a primary-air inflow path 18 that tangentially communicates with the airflow path 16; and a diffuser that is connected to an open end of the main body 17 and has a throat portion at which a tip portion of the nozzle 15 is disposed. An inner wall 18A of the primary-air inflow path 18, which communicates with the scroll-shaped airflow path 16, is offset outward from the center of the nozzle 15, and primary air introduced from the primary-air inflow path 18 flows into the scroll-shaped airflow path 16 from one direction.

Abstract: Provided is a vehicle heating ventilation and air conditioning unit capable of improving the performance of a side demister in a foot mode where a DEF damper is set to a small degree of opening, and capable of securing window clearness of side window glass.

Abstract: Provided is a vehicle air conditioner capable of maintaining comfortable temperature-controlling properties by improving the air mixing performance while reducing separation in the air channel to increase the air flow rate and reduce noise.

Abstract: An object is to provide a vehicle air conditioner that has increased heating ability and reduced noise by improving the heat-exchange efficiency of a heater core by improving an air inlet channel of the heater core and that suppresses stagnation and separation of an air flow at the air inlet channel. Provided is an air-mixing damper type vehicle air conditioner (1) including an air-mixing damper (6), wherein a heater-core inlet channel sidewall (2A) of a casing (2) from a sealing portion (11) of the casing (2) to an edge of a heater core (5) is an inclined surface (30), the sealing portion (11) being contacted by a tip portion (6C) of the air-mixing damper (6) when the inlet of a heating-side air channel (13) is completely closed, and wherein the inclined surface (30) is formed as a curved surface protruding toward the inlet channel of the heater core (5).
