Definitions

  • the present invention relates to an air-mixing-type vehicle air-conditioning apparatus having a heater core and an air mixing damper.
  • An HVAC unit (heating ventilation and air conditioning unit) of an air conditioning apparatus to be installed in a vehicle is structured such that an evaporator, an air mixing damper, and a heater core are disposed in an air flow path in a unit case, sequentially from the upstream side of the air flow path, and air whose temperature has been adjusted by these units is blown into the vehicle interior selectively from any of a face vent duct, a foot vent duct, and a defroster vent duct, which are formed at the downstream side thereof, via a plurality of blowing-mode switching dampers.
  • the air flow path is branched into a bypass flow path and a heating flow path at a downstream side of the evaporator, and the heater core is disposed in the heating flow path.
  • the ratios of airflows to be separately circulated to the bypass flow path and the heating flow path can be adjusted by the rotation angle of the air mixing damper, and the airflow passing through the bypass flow path and the airflow passing through the heater core meet at a downstream area of the air mixing damper and are mixed, thereby producing air that is adjusted to a set temperature.
  • the heater core is disposed on the bottom face of the unit case so as to intersect the heating flow path, and an upper surface thereof is supported along the entire width by a heater-core upper-portion supporting part that extends from right and left side faces of the unit case along the entire width in the width direction.
  • the heater-core upper-portion supporting part segments the air flow path at the upper portion of the heater core (for example, see PTLs 1, 2, and 3).
  • the lower portion of the heater core disposed in the heating flow path is supported on the bottom face of the unit case, and the entire upper surface thereof in the width direction is supported by the heater-core upper-portion supporting part, which extends from the right and left side faces of the unit case along the entire width in the width direction.
  • the heater-core upper-portion supporting part having at least a length equal to half the length of the unit case in the width direction.
  • this heater-core upper-portion supporting part is large in size in the width direction, the draft angle needs to be large during plastic molding, the wall thickness of a root portion thereof is increased, and the wall thickness of a tip portion thereof is reduced, there is a problem in that the wall is likely to lean (to be tilted), thereby leading to a poor molding accuracy. This problem is difficult to avoid with current plastic molding accuracy, and it is difficult to set a constant wall angle of the unit case.
  • a certain space exists between the heater-core upper-portion supporting part and the rotating shaft of the air mixing damper, and cool air cooled by the evaporator flows through this space. Because it is difficult to set a constant wall angle of the unit case, the space becomes non-uniform, thus causing a non-uniform amount of bypass cool air and deterioration of the temperature control performance.
  • the present invention has been made in view of such circumstances, and an object thereof is to provide a vehicle air-conditioning apparatus in which a space formed between the upper surface of the heater core and the rotating shaft of the air mixing damper can be set to a given axially-uniform space, thereby making the temperature adjustment easier and improving the temperature control performance.
