Abstract

The disclosure provides an airflow regulation and control apparatus. A ventilation hole is formed in a windshield in a penetrating manner; a rectangular plate is mounted on the windshield; the rectangular plate is lifted by means of power provided by a lifting wing disposed thereon, and the height of the rectangular plate when moving upwards exceed the height of an upper edge of a main body portion of the windshield; when wind strength is low, the rectangular plate is located at a lower portion under the action of gravity and shields the ventilation hole; when the wind strength is increased, the lifting wing is blown by an airflow to generate upwards lifting force, and drives the rectangular plate to moved upwardly so as to shield an opening in an upper portion of the windshield and block the airflow.

First claim

What is claimed is:

1. An airflow regulation and control apparatus, comprising a windshield, wherein a ventilation hole is formed in the windshield in a penetrating manner;
a rectangular plate being slidingly mounted on the windshield, the rectangular plate being capable of moving vertically relative to the windshield;
and a lifting wing being arranged on the rectangular plate, and the lifting wing being blown by an airflow to generate upward lifting force, and driving the rectangular plate to upwards moved upwardly so as to shield an opening in an upper portion of the windshield and block the airflow, so that the airflow flows through the ventilation hole and an upper portion and both sides of a wind blocking surface defined by the windshield and the rectangular plate.

2. The airflow regulation and control apparatus according to claim 1 , wherein an upper surface of the lifting wing is a curved surface and a lower surface of the lifting wing is a flat surface.

3. The airflow regulation and control apparatus according to claim 1 , wherein there are two lifting wings, the two lifting wings are respectively located at both sides of the rectangular plate, a height of the lifting wings being lower than a height of an upper edge of the rectangular plate.

4. The airflow regulation and control apparatus according to claim 1 , wherein the windshield is arranged in two layers, the rectangular plate being sandwiched between the two layers.

5. The airflow regulation and control apparatus according to claim 1 , wherein both sides of the windshield protrude upwards and are provided with a guide rail, the guide rail being capable of limiting the highest position of the rectangular plate.

6. The airflow regulation and control apparatus according to claim 5 , wherein a width of the ventilation hole is less than one third of a width of the windshield, a height of the ventilation hole being less than a height of the windshield, and a top end of the ventilation hole being communicated with the outside.

7. The airflow regulation and control apparatus according to claim 1 , wherein a base is arranged on a lower surface of the windshield, a thickness of the base being greater than a thickness of the windshield.

8. The airflow regulation and control apparatus according to claim 7 , wherein both ends of the base in a length direction respectively extend out of the windshield to form connecting lugs, the windshield being fixed to a main board in a bolted manner through the connecting lugs.

9. A server, comprising the airflow regulation and control apparatus according to claim 1 .

10. The server according to claim 9 , wherein one side or both sides of the windshield are provided with a flow guiding cover, the flow guiding cover being configured to lead airflow to blow to a component with a higher calorific value.

11. The server according to claim 10 , wherein the flow guiding cover is a tapered cylindrical structure.

12. The server according to claim 10 , wherein the airflow regulation and control apparatus is arranged in front of the component.

13. The server according to claim 9 , wherein the server comprises a main board, the windshield is fixedly arranged.

14. The server according to claim 13 , wherein the windshield is approximately perpendicular to a surface of the main board.

15. The airflow regulation and control apparatus according to claim 1 , wherein a penetrating direction of the ventilation hole is perpendicular to the wind blocking surface of the windshield.

16. The airflow regulation and control apparatus according to claim 1 , wherein a width of the ventilation hole is smaller than a width of the windshield.

17. The airflow regulation and control apparatus according to claim 1 , wherein the ventilation hole in a middle of the windshield.

18. The airflow regulation and control apparatus according to claim 17 , wherein the ventilation hole is symmetrically relative to a symmetry axis of the windshield.

19. The airflow regulation and control apparatus according to claim 1 , wherein a curvature of an upper surface of a vertical section of the lifting wing is greater than a curvature of a lower surface of the vertical section of the lifting wing.

20. The airflow regulation and control apparatus according to claim 5 , wherein the guide rail is a two-layer structure with an enclosed upper end part.
