權(quán)利要求
What is claimed is:1. A cooling system disposed on a vehicle, comprising:an enclosure comprising a vent at a base of the enclosure, the enclosure housing one or more sensors; and a deflector connected to the enclosure and configured to channel an airflow and direct the channeled airflow into the vent of the enclosure, wherein the deflector curves outward as a distance between the deflector and the enclosure increases. 2. The cooling system of claim 1 , further comprising a groove in which the deflector moves up and down. 3. The cooling system of claim 2 , wherein the one or more sensors is configured to determine a speed of the vehicle, an internal temperature of an enclosure, an external temperature, and a wind speed, and further comprising:a controller configured to adjust a height of the deflector by moving the deflector up or down in the groove, based on the speed of the vehicle, the internal temperature of the enclosure, the external temperature, a difference between the internal temperature of the enclosure and the external temperature, or the wind speed. 4. The cooling system of claim 3 , wherein:the enclosure further comprises a fan; and the controller is further configured to adjust a rotation speed of the fan based on the height of the deflector. 5. The cooling system of claim 3 , wherein the controller is configured to operate the deflector in an inactive mode in which the deflector is fully embedded in the groove and an active mode in which the deflector extends above the groove. 6. The cooling system of claim 3 , wherein the controller is configured to operate the deflector in a first mode in which the deflector extends to a first height above the groove and a second mode in which the deflector extends to a second height above the groove, the second height being greater than the first height. 7. The cooling system of claim 6 , wherein, a length of a portion of the deflector above a roof of the vehicle in the first mode is smaller than a length of a portion of the deflector above the roof of the vehicle in the second mode. 8. The cooling system of claim 1 , wherein a height of the deflector decreases based on a distance from the deflector to the enclosure. 9. The cooling system of claim 8 , wherein the height of the deflector decreases at a nonconstant rate of decrease as the distance from the deflector to the enclosure increases. 10. The cooling system of claim 3 , wherein the controller is configured to adjust a height of the deflector by moving the deflector up or down in the groove, based on an anticipated speed of the vehicle, an anticipated internal temperature of the enclosure, an anticipated external temperature, a difference between the anticipated internal temperature of the enclosure and the anticipated external temperature, or an anticipated wind speed. 11. The cooling system of claim 1 , wherein the deflector comprises a first section in which a height of the deflector decreases as a distance from the deflector to the enclosure increases and a second section in which a height of the deflector increases as a distance from the deflector to the enclosure increases. 12. The cooling system of claim 1 , further comprising a second deflector disposed on an opposite side of the vent and being spaced equidistant from the vent as the deflector. 13. The cooling system of claim 1 , further comprising a second deflector that forms a mirror image with the deflector with respect to an axis through the vent and parallel to a flat section of a roof of the vehicle. 14. A cooling system disposed on a vehicle, comprising:an enclosure comprising a vent at a base of the enclosure, the enclosure housing one or more sensors; and a deflector connected to the enclosure and configured to channel an airflow and direct the channeled airflow into the vent of the enclosure, wherein the deflector extends along a straight line from the enclosure. 15. A cooling system disposed on a vehicle, comprising:an enclosure comprising a vent at a base of the enclosure, the enclosure housing one or more sensors; a deflector connected to the enclosure and configured to channel an airflow and direct the channeled airflow into the vent of the enclosure; a second deflector disposed on an opposite side of the vent and being spaced equidistant from the vent as the deflector.
