Embodiment Construction

[0014] Please refer to figure 1 and figure 2 , the first embodiment of the fan fixing device of the present invention can fix several fans 20 . The fan fixing device includes a fan frame 10 , four pairs of vertically extending fixing pieces 30 , four first windshield pieces 40 and four second windshield pieces 50 .

[0015] Each fan 20 includes a side plate 21 . Four corners of the side plate 21 respectively define a fixing hole 213 .

[0016] The fan frame 10 includes an elongated base 12 and an elongated fixing wall 14 vertically extending upward from a rear edge of the base 12 . The fixed wall 14 defines four vents 141 at intervals along the horizontal direction. The fixing wall 14 defines a first through hole 143 at the upper portion of each vent 141 , and defines a second through hole 145 at the lower portion of each vent 141 . The fixing wall 14 defines a positioning slot 147 above each first through hole 143 .

[0017] Each fixing member 30 includes a mounting el...

Abstract

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

Description

technical field [0001] The invention relates to a fan fixing device. Background technique [0002] In an electronic product, several fans are usually installed to dissipate heat for electronic components in the electronic product. However, when some fans stop rotating due to a fault, the faulty fan will generate backflow of air flow, which will cause air flow turbulence and affect the heat dissipation of the system. Contents of the invention [0003] In view of the above, it is necessary to provide a fan fixing device capable of preventing backflow of air flow. [0004] A fan fixing device is used for fixing a fan, the fan includes a side plate, two fixing holes are arranged on the upper part of the side plate, the fan fixing device includes a fan frame, and the fan frame includes a fixing hole provided with a vent wall, the fixed wall is respectively provided with a first through hole on the upper part of both sides of the vent, and the fan fixing device also includes t...
