Abstract
An electronic device includes an air dam module. The air dam module includes a frame and a rotating member. The frame defines a vent. The rotating member is received in the vent and includes a pivot rotatably connected to midpoints of opposite sides of the frame, a first shield plate extending up from a top side of the pivot, to vertically block an upper half of the vent. In addition, a second shield plate heavier than the first shield plate and extending down from a bottom side of the pivot, to vertically block a lower half of the vent by gravity.
Claims15
An air dam module, comprising:
- a frame defining a vent through a front end and a rear end of the frame;
- and
- a rotating member received in the vent, and comprising a horizontal pivot, a first shield plate extending up from a top side of the pivot, and a second shield plate heavier than the first shield plate extending down from a bottom side of the pivot, wherein opposite ends of the pivot are rotatably connected to midpoints of opposite sides of the frame, and upon a condition that the gravity of the second shield plate is not overcome by an airflow passing through the vent, the gravity of the second shield plate causes the rotating member to rotatably stay in a position where the second shield plate vertically blocks a lower half of the vent and the first shield plate vertically blocks an upper half of the vent.
An electronic device, comprising:
- a chassis;
- and
- an air dam module comprising a frame mounted to the chassis and defining a vent extending from front to back, wherein the frame has the same shape and size as a standard fan, the air dam module comprises a rotating member received in the vent, the rotating member comprises a horizontal pivot, a first shield plate extending up from a top side of the pivot, and a second shield plate heavier than the first shield plate and extending down from a bottom side of the pivot, opposite ends of the pivot are rotatably connected to midpoints of opposite sides of the frame, and upon a condition that the gravity of the second shield plate is not overcome by an airflow passing through the vent, the gravity of the second shield plate causes the rotating member to rotatably stay in a position where the second shield plate vertically blocks a lower half of the vent and the first shield plate vertically blocks an upper half of the vent.
An electronic device, comprising:
- a chassis;
- a standard fan mounted in the chassis and comprising a first frame, the first frame defining a first vent through a front end and a rear end of the first frame;
- and
- an air dam module mounted to the front end of the first frame, the air dam module comprising a second frame defining a second vent aligning with the first vent, wherein the second frame has the same shape and size as the first frame, the air dam module comprises a rotating member received in the second vent, the rotating member comprises a horizontal pivot, a first shield plate extending up from a top side of the pivot, and a second shield plate heavier than the first shield plate and extending down from a bottom side of the pivot, opposite ends of the pivot are rotatably connected to midpoints of opposite sides of the second frame, upon a condition that the gravity of the second shield plate is not overcome by an airflow passing through the vent, the gravity of the second shield plate causes the rotating member to rotatably stay in a position where the second shield plate vertically blocks a lower half of the vent and the first shield plate vertically blocks an upper half of the vent, and wherein the second shield plate rotates forward 90 degrees, and the first shield plate rotates backward 90 degrees, in response to the standard fan blowing air towards the air dam module.
