Description

fan mount

【Technical field】

The invention relates to a fan fixing device, in particular to a fan fixing device which can be used to fix fans of different models.

【Background technique】

A system fan is generally installed in the computer mainframe case, which is mainly used to remove heat from the computer mainframe case to avoid overheating of the computer system.

Such as a computer fan positioning device disclosed in Chinese Patent No. 98116072.7, the fan is installed on the computer mainframe chassis, which can introduce the air outside the computer mainframe chassis and strengthen the air convection in the computer mainframe chassis, and can cooperate with the electronic components on the computer substrate. Components, such as the position of the central processing unit, change the position of the fan to concentrate the air convection on the central processing unit, so that the central processing unit can obtain the best cooling effect. It mainly includes a fan seat and a bracket. The fan seat is used to install a computer fan. The support includes a fixing frame and a fan fixing frame. The fixing frame is fixed on the computer mainframe chassis. The fan fixing frame can be equipped with a fan seat, and the position of the fan seat can be adjusted according to the configuration of the computer substrate. Although the computer fan positioning device can achieve the best heat dissipation effect for the central processing unit, only one type of fan can be installed in the fan seat, and in some specific cases, such as system fan failure or computer system testing in the laboratory At that time, there is no fan of the corresponding type available, but there is an urgent need to use the computer or in order not to affect the progress of the test work. At this time, even if there are other types of fans at hand, the fan base can only be installed with one type of fan. Due to the limitation, other types of fans cannot be installed at all, so it is necessary to design a fan fixing device that can fix fans of different types.

【Content of invention】

In view of the above, it is necessary to provide a fan fixing device capable of fixing fans of different models.

A fan fixing device, which can be used to fix different types of fans. The four corners of the fan are provided with locking holes. The fan fixing device includes a mounting part and a fixing part for installing the mounting part. The fixing part includes several fixing parts. The fixing frame of the arm, each fixing arm is provided with a fixing structure corresponding to the locking holes of at least two different types of fans.

Compared with the prior art, the fan fixing device achieves the purpose of fixing different types of fans by means of the locking piece to make the fixing structure of the fixing piece fit into the locking holes of different types of fans.

Please refer to FIG. 1 and FIG. 2 , the fan fixing device of the present invention can be used to fix fans of different types, and the preferred embodiment of the fan fixing device includes fixing parts 10 capable of fixing fans of different types and installation parts for installing the fixing parts 10 40 pieces.

The fixing member 10 includes a square hollow frame body 12 and a “cross”-shaped fixing bracket 20 disposed in the frame body 12 . The four corners of the frame body 12 are respectively provided with mounting holes 14; the fixed frame 20 includes a circular central part 22 placed in the center of the frame body 12 and fixed arms 24 extending from the periphery of the central part 22 to the four corners of the frame body 12, each fixed arm 24 is provided with a fixed structure, such as the fixed holes 34, 32, 30, 28, 26 provided in each fixed arm 24, the fixed holes 34, 32, 30, 28, 26 are respectively extended along the corresponding fixed arm 24 According to the direction, they correspond to five types of fans respectively.

The mounting part 40 is provided with a heat dissipation net 42 having a plurality of heat dissipation holes, and through holes 44 corresponding to the mounting holes 14 of the fixing part 10 are respectively defined around the heat dissipation net 42 .

Please refer to FIG. 3 at the same time. During assembly, use a locking member 92 (such as a screw) to pass through the fixing hole 28 of the fixing member 10 and screw it to the locking hole 84 of the fan 82, thereby fixing the fan 82 to the fixing member 10; The connecting part 94 passes through the through hole 44 of the mounting part 40 and is screwed into the mounting hole 14 of the fixing part 10 to fix the fixing part 10 and the fan 82 to the mounting part 40 together.

Please continue to refer to Figure 4. When there is only the fan 86 at hand, use the locking piece to pass through the fixing hole 30 of the fixing piece 10 (as shown in Figure 2) and screw it into the locking hole 87 of the fan 86 to fix the fan 86, and then follow the The aforementioned method fixes the fixing member 10 and the fan 86 to the mounting member 40 together.
