Description

fan module

technical field

The utility model relates to a fan module, in particular to a fan module used in servers or computers.

Background technique

As we all know, electronic components often generate a certain amount of heat when they are working. If the heat is not taken away in time, it will cause damage to the electronic components. Therefore, some cooling devices are often needed to dissipate heat from electronic components.

For example, in a computer or server case, a fan is generally installed to achieve the purpose of heat dissipation. During installation, the fan is first locked in a fixing frame by screws, the fixing frame is provided with a plurality of through holes, and a side panel or a rear panel of the case is provided with a plurality of screw holes corresponding to the through holes. Then, the fan and the fixing frame are leaned against the side plate or the rear plate, and the through holes of the fixing frame are aligned with the screw holes of the side plate or the rear plate. A plurality of screws penetrate through the through holes of the fixing frame and are locked in the screw holes of the side plate or the rear plate, so that the fan can be fixed in the computer or server case. However, this fixing method using screws is extremely inconvenient when disassembling the fan.

Contents of the invention

In view of the above, it is necessary to provide a fan module that facilitates disassembly and assembly of the fan.

A fan module includes a fan, a bracket and a locking member fixed on the fan, the bracket includes two side plates parallel to each other, the two side plates can accommodate the fan therebetween, the One of the two side plates of the bracket is provided with a buckle hole, and the locking member is clamped between the fan and the side plate provided with the buckle hole, and an elastic arm is arranged on it, and the elastic arm is A buckle block for buckle fit with the buckle hole is provided.

Compared with the prior art, the fan module of the utility model is snap-fitted with the buckle hole of the side plate of the bracket through the buckle block of the elastic arm, so as to facilitate the fixing of the fan and the locking member to the side plate of the bracket. Between the two side panels, when disassembling, the elastic arm is pulled to disengage the buckle block from the buckle hole, and the fan and the locking piece can be taken out from the storage space, which is very convenient for fixing and disassembling. described fan.

Detailed ways

Please refer to FIG. 1 , a fan module according to a preferred embodiment of the present invention includes a fan 10 , a bracket 20 and a locking member 30 .

The fan 10 has two sidewalls 12 parallel to each other, and four through holes 122 are defined in four corners of each sidewall 12 .

The bracket 20 is installed in a computer or server case 40 and includes a plurality of storage spaces, each of which can accommodate one fan 10 . Each of the accommodating spaces is surrounded by a front panel 22 , a rear panel 24 and two side panels 26 . The front panel 22 is parallel to the rear panel 24 , and each defines ventilation holes 222 , 242 . The two side panels 26 are respectively perpendicular to the front panel 22 and the rear panel 24 , and each defines a buckle hole 262 .

Please refer to FIG. 2 and FIG. 3 , the locking member 30 is substantially in an “L” shape, and includes a mounting portion 32 and an operating portion 34 perpendicular to the mounting portion 32 . The upper part of the installation part 32 is provided with an elastic arm 322 extending to the operation part 34, and the upper edge and the two side edges of the elastic arm 322 form gaps with the operation part 34 and the installation part 32 respectively, so as to The elastic arm 322 can be elastically deformed. A locking block 3222 corresponding to the locking hole 262 of the side plate 26 protrudes outward from the middle of the outer surface of the elastic arm 322 , and a notch 3224 is defined on the upper side of the locking block 3222 . The upper end of the elastic arm 322 is bent to form a folded wall 3226 , and the notch 3224 extends to the folded wall 3226 . The outer surface of the mounting part 32 is respectively provided with two elastic pieces 324 protruding outward near the two long edges, and the inner surface is respectively protruded with an elastic post 326 near each long edge. The protruding post 326 A hemispherical protrusion 3262 protrudes outward from the ends of each. An arc-shaped notch 342 is defined on an edge of the operating portion 34 opposite to the upper edge of the elastic arm 322 . The locking member 30 is bent inwards to form a folded edge 36 on two side edges of the mounting portion 32 and the operating portion 34 .

Please refer to FIG. 4 , when installing, place the fan 10 on the protrusion 3262 of the stud 326 of the locking member 30 , and push the fan 10 to move toward the installation portion 32 of the locking member 30 , the fan 10 presses the protrusion 3262 to elastically deform the protrusion 326 inward, and the protrusion 3262 slides into the space between the two sidewalls 12 of the fan 10 . When the protrusion 3262 reaches the position of the through hole 122 of the fan 10, the protrusion 326 elastically recovers so that the protrusion 3262 is inserted into the through hole 122, and the protrusion 326 is clamped on the fan. Between the two side walls 12 of the fan 10, the fan 10 is fixed with the locking member 30. At this time, the folded edges 36 of the locking member 30 respectively abut against the two side walls 12 of the fan 10, so that the operation part 34 slightly protrudes from the upper edge of the two side plates 12 of the fan 10, so as to It is convenient to pull the operation part 34 when dismounting.

The fan 10 is slid into the receiving space of the bracket 20 together with the locking member 30, and the side plate 26 elastically deforms the elastic arm 322 by pressing the buckle block 3222, and the fan 10 10 and the locking member 30 can further slide into the receiving space. When the buckle block 3222 reaches the position of the buckle hole 262 of the side plate 26, the elastic arm 322 returns elastically so that the buckle block 3222 snaps into the buckle hole 262, thereby blocking all The fan 10 and the locking member 30 slide out of the receiving space, as shown in FIG. 5 . At this time, the notch 3224 of the elastic arm 322 slightly exposes the receiving space, and the elastic piece 324 of the locking member 30 is elastically deformed by being pressed by the side plate 26, thereby generating an elastic force to lock the lock. The firmware 30 and the fan 10 are stably accommodated in the accommodation space.

After installation, the two side walls 12 of the fan 10 are perpendicular to the two side plates 26 of the bracket 20, and the locking member 30 is clamped between the side plate 26 provided with the buckle hole 262 and the side plate 26 of the bracket 20. Between the fans 10 , the mounting portion 32 of the locking member 30 is roughly parallel to the two side plates 26 of the bracket 20 . Air flows in through the ventilation holes 222 of the front panel 22 , passes through the fan 10 , and then flows out of the ventilation holes 242 of the rear panel 24 . The flow direction of the air in the accommodation space of the fan 10 is substantially perpendicular to the front panel 22 and the rear panel 24 and parallel to the side panel 26 . The locking member 30 is fixed on the fan 10 along a direction perpendicular to the wind flow of the fan 10 .

When dismounting, operate the locking member 30 through the notch 3224 of the elastic arm 322 and the notch 342 of the operating part 34, and at the same time, pull the elastic arm 322 to elastically deform it, and make the elastic arm 322 The snapping block 3222 of the receiving space is disengaged from the snapping hole 262 of the side plate 26 , and then the locking member 30 is pulled upwards so that the locking member 30 slides upward together with the fan 10 out of the receiving space.
