Abstract

A mounting apparatus includes a bracket, two mounting members, a first shield plate, and a second shield plate. The bracket includes a fixing plate defining a vent. Two through holes are defined in an upper portion of the fixing plate at opposite sides of the vent. Upper portions of the mounting members extend through the through holes and engage in two fixing holes of upper portions of a sidewall of a fan. Opposite ends of the top of the first shield plate are pivotably connected to upper portions of the mounting members, and opposite ends of the top of the second shield plate are pivotably connected to lower portions of the mounting members. The first and second shield plates hang vertically by gravitational force, to cover the vent. When the fan blows air towards the first and second shield plates, the first and second shield plates are capable of rotating away from the fan 90 degrees.

Description

Fan fixture

The present invention relates to a fan fixing device.

In electronic products, a plurality of fans are usually installed to dissipate heat from electronic components in the electronic product. However, when some fans stop rotating due to a fault, windflow will occur at the faulty fan, causing disturbance of the wind flow and affecting system heat dissipation.

In view of the above, it is necessary to provide a fan fixing device capable of preventing backflow of wind.

A fan fixing device is used for fixing a fan. The fan includes a side plate. The upper part of the side plate is provided with two fixing holes. The fan fixing device includes a fan frame, and the fan frame includes a fixed wall provided with a vent. The fixing wall is respectively provided with a first through hole on the upper part of the two sides of the venting port, and the fan fixing device further comprises two vertically extending fixing members, a first wind blocking piece and a second wind blocking piece, the two The upper part of the fixing member is respectively inserted into the two fixing holes of the fan, and the two ends of the top of the first windshield are pivotally connected to the upper portions of the two fixing members, respectively. The two ends of the top of the second windshield are respectively pivotally connected to the lower portions of the two fixing members, and the first and second windshields are vertically shielded from the side of the venting opening facing the fan by gravity. The first and second windshields are capable of rotating away from the fan to a maximum of 90 degrees when subjected to the wind force of the fan.

Compared with the prior art, the fan fixing device pivotally mounts a first windshield and a second windshield in front of the vent, and the first and second windshield can be rotated by the wind force of the fan to The maximum 90 degrees does not affect the fan's airflow. When the fan does not rotate, the first and second windshields on the front side of the vent remain vertical, which blocks the return airflow.
