Problems solved by technology

However, when a fan stops rotating due to a fault or a fan is not installed in a certain fan position in the fan rack, the air flow backflow will be generated at the faulty fan or the uninstalled fan, which will cause air flow disorder and affect the heat dissipation of the system.

Embodiment Construction

[0012] Please refer to figure 1 and figure 2 , a preferred embodiment of the fan fixing device of the present invention can fix several fans 20 . The fan fixing device includes a fan frame 10 , two installation rods 30 and eight windshields 40 .

[0013] Each fan 20 includes two opposite side panels 21 . Four corners of each side plate 21 respectively define a fixing hole 213 .

[0014] 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, and four through holes 143 are formed around each vent 141 . Both ends of the fixing wall 14 protrude forward from a first connecting portion 145 at the top and a second connecting portion 147 at the middle. Each first connecting portion 145 defines a first through hole 146 facing the other first connecting portion 145 . Each second connecting portion 147 defines a...

Abstract

The invention relates to a fan fixing device comprising a fan rack. The fan rack comprises a plurality of ventilating openings and a fixing wall, and the ventilating openings are formed horizontally at intervals. A fan, directly facing to each ventilating opening and blowing air towards the same, can be mounted on the rear side of the fixing wall; two mounting rods extending horizontally are arranged at the top and in the middle of the front side of the fixing arm; each mounting rod is pivotally provided with a plurality of air blocking pieces; the air blocking pieces are kept upright under the action of gravity to enable the front side of each ventilating opening to cover two vertically-distributed air blocking pieces; the two air blocking pieces on the front side of each ventilating opening can rotate frontwards and upwards by 90 degrees under the action of air, from front to back, of the fan directly facing to the ventilating opening, and air outgoing of the fans is unaffected; when some fans do not rotate, or some ventilating openings are not provided with the fans in the rear side, the air blocking pieces on the front sides of the corresponding ventilating openings are kept upright, and accordingly backflow air flow can be blocked.

Description

technical field [0001] The invention relates to a fan fixing device. Background technique [0002] In an electronic product, usually a plurality of fans are mounted on a fan frame to dissipate heat for electronic components in the electronic product. However, when a fan stops rotating due to a fault or a fan is not installed in a certain fan position in the fan rack, the air flow backflow will be generated at the faulty fan or the uninstalled fan position, which will cause air flow disturbance and affect system heat dissipation. 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, comprising a fan frame, the fan frame includes a fixed wall provided with a number of vents at intervals along the horizontal direction, the rear side of the fixed wall is facing each vent and can be installed towards the vent For the blowing fan, the front side of the fi...
