Abstract

A structure of an intercooler cover integrated into a fan shroud includes an intercooler rear-side portion mounted to a rear side of the intercooler. A cooling module rear-side portion is mounted to a rear side of a cooling module. A ventilator communicates with one side of the intercooler rear-side portion and one side of the cooling module rear-side portion.

First claim

What is claimed is:

1. A structure of a vehicle intercooler cover integrated into a fan shroud, the structure comprising:
an intercooler rear-side portion which covers a rear side of an intercooler;
a cooling module rear-side portion which covers a rear side of a cooling module; and
a ventilator which allows communication between one side of the intercooler rear-side portion and one side of the cooling module rear-side portion,
wherein the ventilator comprises a partition wall which prevents air from flowing backward from the cooling module rear-side portion to the intercooler rear-side portion.

2. The structure of claim 1 , further comprising:
at least one flap door which is installed at another side of the intercooler rear-side portion, the other side being vertical to a vehicle driving direction to block heat to be transferred from an engine compartment to the intercooler when a vehicle stops and idles.

3. The structure of claim 2 , further comprising:
a hinge rotatably coupling the flap door with the intercooler rear-side portion.

4. The structure of claim 3 , wherein the hinge is a spring.

5. The structure of claim 2 , wherein the flap door is opened when the vehicle travels.

6. The structure of claim 2 , wherein the flap door is closed when the vehicle stops with idling.

7. The structure of claim 2 , wherein the flap door is formed of an insulator.

8. The structure of claim 2 , wherein the intercooler rear-side portion comprises a stopper formed at an opening of the flap door to open the flap door in one direction opposite to the vehicle driving direction.

9. The structure of claim 1 , wherein the partition wall is installed at the one side of the cooling module rear-side portion.

10. The structure of claim 1 , wherein the partition wall comprises a first partition wall which is connected to a front end toward a rear end of the ventilator with respect to a vehicle driving direction.

11. The structure of claim 1 , wherein the partition wall comprises a second partition wall which is slantingly connected to a rear end of the ventilator with respect to a vehicle driving direction into the ventilator.

12. The structure of claim 1 , wherein a central cross-sectional area of the ventilator is wider than cross-sectional areas of both ends of the ventilator.

13. The structure of claim 12 , wherein the ventilator has a diffuser shape having an increasing cross-sectional area, a pipe shape having a uniform cross-sectional area, and a nozzle shape having a decreasing cross-sectional area,
wherein the cross-sectional areas of the ventilator are sequentially coupled from the intercooler rear-side portion toward the cooling module rear-side portion.

14. A method for operating a structure of a vehicle intercooler cover integrated into a fan shroud, the method comprising:
opening a flap door by headwind when a vehicle travels; and
closing the flap door when the vehicle stops and idles
wherein the structure includes an intercooler rear-side portion, a cooling module rear-side portion, and a ventilator, and
wherein the ventilator allows communication between the intercooler rear-side portion and the cooling module rear-side portion and has a partition wall which prevents air from flowing backward from the cooling module rear-side portion to the intercooler rear-side portion.

15. The method of claim 14 , further comprising prior to the step of opening:
determining whether the vehicle travels.

16. The method of claim 15 , comprising:
closing the flap door when the vehicle does not travel.

17. The method of claim 14 , further comprising:
determining whether a vehicle engine is off.
