Air flow device for vehicle

1. An air flow device for a vehicle,

the vehicle including:

a vehicle compartment;

a windshield at a front of the vehicle compartment;

an instrument panel dashboard disposed below the windshield; and

a seat disposed closer to a back end of the vehicle than the instrument panel dashboard,

wherein the instrument panel dashboard includes:

an upper surface that faces upward in opposition to the windshield; and

a lower surface that faces downward in opposition to a floor of the vehicle, and

wherein the upper surface includes:

(i) a front part adjacent to an edge of the windshield, wherein the front part of the upper surface faces upward in opposition to the windshield in a perpendicular direction; and

(ii) a back part closer to the back end of the vehicle than the front part, wherein the back part of the upper surface diagonally faces an upper part of the seat of the vehicle, and wherein the back part is inclined more than the front part and is adjacent to the front part, and

the air flow device comprising:

a first inlet disposed on the front part of the upper surface adjacently to the edge of the windshield, the first inlet extending along the edge of the windshield;

a first outlet disposed on the front part of the upper surface, the first outlet extending along a direction parallel to the first inlet;

a second inlet disposed on the back part of the upper surface, the second inlet extending along the direction parallel to the first inlet;

a second outlet disposed on the back part of the upper surface apart from the second inlet, the second outlet extending along the direction parallel to the first inlet; and

a blower coupled to the first inlet, the first outlet, the second inlet, and the second outlet via a flow path,

wherein the blower makes a first air flow along the upper surface from the first outlet to the first inlet, and makes a second air flow along the upper surface from the second outlet to the second inlet, and

wherein a flow direction of the first air flow and a flow direction of the second air flow are identical.

2. The air flow device according to according to claim 1 , wherein the air flow device further comprises a guide including a plasma actuator on the upper surface of the instrument panel dashboard.

3. The air flow device according to claim 1 , wherein, in the extending direction of the first inlet, the first outlet, the second inlet, and the second outlet have lengths substantially identical to a length of the first inlet.

4. The air flow device according to claim 1 , wherein the upper surface of the instrument panel dashboard gradually inclines downward to a back of the vehicle.

5. The air flow device according to claim 1 , wherein the first inlet, the first outlet, the second inlet, and the second outlet are further coupled to a cooling heat exchanger that cools air via the flow path.

6. The air flow device according to according to claim 5 ,

wherein the lower surface of the instrument panel dashboard gradually inclines upward to a back of the vehicle,

wherein the air flow device further comprises:

a lower surface outlet disposed on the lower surface of the instrument panel dashboard; and

a lower surface inlet disposed on the lower surface of the instrument panel dashboard apart from the lower surface outlet, and wherein the lower surface outlet is coupled to a heating heat exchanger that heats air, and a third air flow heated by the heating heat exchanger is flown from the lower surface outlet into the lower surface inlet.
