Description

{AIR CONDITIONING APPARATUS FOR AUTOMOTIVE VEHICLE}

The present invention relates to an air conditioning system for a vehicle.

In large vehicles such as passenger cars, an overhead type air conditioner may be additionally installed in addition to the main air conditioner installed in front of the driver's seat to cool and heat the passenger space in the first row.

An air conditioner for a vehicle is installed on the ceiling of a vehicle and can supply cool air to the passenger space of two or three rows. To this end, the air conditioner for a vehicle may include an air conditioner case fixed to a roof panel of the vehicle, and an evaporator, a blower fan, etc. placed within the air conditioner case.

As described above, when the vehicle air conditioner is configured, since cold refrigerant circulates inside the evaporator during operation, condensate is generated around the evaporator during the heat exchange process with the outside air. This condensate flows down the evaporator in the direction of gravity or falls to the bottom of the air conditioner case by the blown wind, and is then discharged to the outside through the condensate drain portion formed at the bottom of the air conditioner case. At this time, the vehicle air conditioner has the structural characteristics of a small height difference between the bottom of the air conditioner case and the evaporator, and a small angle of inclination for drainage.

In these conventional vehicle air conditioners, condensate formed in the evaporator or at the bottom of the air conditioner case may be mixed with the blown air and dispersed, and there is a risk that the dispersed condensate may be discharged into the vehicle interior through the air discharge port, causing discomfort to the passengers.

Referring to FIGS. 1 to 3, the vehicle air conditioning device includes a case part (110), a driving part (120), a drain part (130), and a condensate filter part (140).

The case part (110) forms the exterior. At this time, a driving part (120) is arranged inside the case part (110). An air discharge port (110h) is formed at the front of the case part (110), and an air intake port (not shown) is formed at the other side of the case part (110).

The case part (110) can have air drawn into the interior through the intake port (not shown), and the drawn air can be cooled to a predetermined temperature by the driving part (120) and then discharged to the exterior through the air discharge port (110h). At this time, the air discharge port (110h) can be connected to the vehicle interior. In addition, a grill structure can be combined with the air intake port (not shown) and the air discharge port (110h).

Referring to FIG. 2, the case part (110) may be composed of a first body (111), a second body (112), and a third body (113).

The first body (111) may have the above driving unit (120) placed thereon. At this time, a blower (121) may be placed at the rear of the first body (111), and an evaporator (122) may be placed at the front of the first body (111). At this time, the first body (111) may be formed such that the length in the horizontal direction is longer than the length in the vertical direction.

The second body (112) can be extended forward from the first body (111). At this time, the second body (112) can be inclined upward so as to go forward.

The third body (113) may extend forward from the second body (112). At this time, the third body (113) may have an air discharge port (211) formed at the front end.

In this way, the vehicle air conditioning system according to the present invention is a roof-type vehicle air conditioning system (Roof HVAC), and the angle of inclination of the second body (112) is relatively small, and the height difference between the lower surfaces of the first body (111) and the third body (1113) is not large, so that condensate collected on the lower surface of the first body (111) may fly away.

The driving unit (120) is placed inside the case unit (110). The driving unit (120) cools the fluid and transports it toward the air discharge port (111). The driving unit (120) may include a blower (121) and an evaporator (122).

The air conditioning device according to the present invention may include the condensate filter unit (140) and the baffle unit (200) at the same time.

The above condensate filter unit (140) is installed in front of the evaporator (122) and passes the fluid that has passed through the evaporator (122). At this time, the condensate filter unit (140) passes the air contained in the fluid and guides some of the condensate contained in the fluid to the drain unit (130) by colliding with it.

At this time, a small amount of condensate may remain in the fluid discharged through the air discharge port (110h) after passing through the condensate filter unit (140). Then, the fluid discharged through the air discharge port (110h) collides with the collision surface (201) of the baffle unit (200), and the remaining condensate may be captured and discharged by the condensate discharge unit (230).

The air conditioning device according to the present invention can improve the efficiency of preventing condensate from flying by first filtering condensate through a condensate filter section and then capturing and discharging the remaining condensate through a baffle section.
