AIR CONDITIONING DEVICE FOR VEHICLE

摘要

In an interior air conditioning unit, a divided case is provided with a main water receiver, a main drain port, a side wall, a secondary drain port, a partition wall, a notch, a droplet reservoir, a path, and a tilted portion. The side wall, the secondary drain port, the notch, the droplet reservoir, the path, and the tilted portion are respectively located such that a condensate water flows out of the main water receiver and reaches the secondary drain port through the notch before a water surface of the condensate water reaches a fitting portion between the divided cases. According to the above-described configuration, the condensate water produced in the cooling heat exchanger can be certainly prevented from leaking through the fitting portion of the air conditioning case.

主权项

1. An air conditioning device for a vehicle comprising:
an air conditioning case that is configured by fitting a plurality of divided cases together and configures an air passage guiding air toward a vehicle compartment of the vehicle; a cooling heat exchanger that has a flat shape, is arranged on a condition of being erected in the air conditioning case, and cools the air; a first water receiver that receives a condensate water produced in the cooling heat exchanger; a first drain hole that drains the condensate water from the first water receiver to an outside of the vehicle compartment; a second water receiver that is located on a downstream side of the first water receiver in an airflow direction and receives the condensate water; a second drain hole that is formed in a bottom portion of the second water receiver on one side in a width direction of the cooling heat exchanger, the second drain hole that drains the condensate water from the second water receiver to the outside of the vehicle compartment through a pathway that is different from a pathway to drain the condensate water from the first drain hole to the outside of the vehicle compartment; a side wall that is located in the second water receiver on an other side in the width direction of the cooling heat exchanger and forms the second water receiver; a partition wall that partitions the first and second water receivers from each other; an opening that is formed in the partition wall, the opening through which the first and second water receivers communicate with each other; and a droplet reservoir that is recessed in the bottom portion of the second water receiver and stores a droplet of the condensate water from the cooling heat exchanger, wherein the air conditioning case has a fitting portion in which two of the plurality of the divided cases fit together, and the opening, the side wall, the droplet reservoir, and the second drain hole are arranged respectively such that the condensate water flows out of the first water receiver and reaches the second drain hole through the opening before a water surface of the condensate water reaches the fitting portion.
