Patent ID: 7310228

Claim:
A air shroud for dissipating heat from an electronic component comprising a air shroud of a pre-determined length and a roughly U-shaped cross section, which is provided with a first opening and a second opening interconnected to form a passage for air flow; a modularized computer case whose interior space is provided with two vertical walls separated by a pre-determined distance, including a first wall and a second wall, respectively; a circuit board being installed on a base plate of the computer case; the air shroud being covered on the circuit board, such that a specific electronic component on the circuit board can be located in the passage; the second opening being corresponding to and connected on the second wall; the first opening being corresponding to and connected on the first wall; a flexible thin piece of an arc-shaped surface being fixed on an internal wall surface inside the air shroud; the arc-shaped surface being able to be deformed to a straight surface to be touched with a top surface of the electronic component; air in the passage flowing quickly in the passage from the first opening to the second opening, to blow toward the electronic component below the thin piece, thereby effectively reducing a working temperature of the electronic component.
