Description

Cooling fan installation mechanism

technical field

The utility model relates to the technical field of fan installation mechanisms, in particular to a cooling fan installation mechanism.

Background technique

With the development of science and technology, computers have entered our daily life. For computers, the core part is the storage device, which is the so-called processor, that is, the hard disk, which stores all the data information of users, and the value of these data. It is far higher than the processor itself. At the same time, the processor is the main component of the computer, and its performance directly affects the running speed of the computer and the user's operating experience. Hard disks are divided into two types according to their working forms, mechanical hard disks and solid-state hard disks (SSD). A mechanical hard disk is a traditional ordinary hard disk, which is mainly composed of a platter, a platter shaft, a magnetic head assembly, a magnetic head drive mechanism, and a control circuit. The solid state drive is an all-electronic structure with no mechanical moving parts. It adopts integrated circuit storage technology and consists of a control unit and a storage unit. When it processes information, it will inevitably generate a lot of heat, causing the temperature in the hard disk to rise sharply. When assembling computers, people have to install a cooling fan mechanism next to the hard disk to ensure the normal use of the hard disk.

At present, the existing cooling fan installation mechanism is easy to vibrate during use, which leads to the problem of excessive computer noise; therefore, it does not meet the existing requirements, and we propose a cooling fan installation mechanism.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-4, an embodiment provided by the present invention: a cooling fan installation mechanism, including a main fan frame 1, the outer wall of the main fan frame 1 is provided with a trapezoidal groove 15, the interior of the main fan frame 1 is provided with Fastening the screw holes 6 can improve the firmness of the main fan frame 1 and avoid large vibrations during use. The side of the fastening screw holes 6 is provided with a chute 12, which can increase the air flow area, thereby It can better dissipate heat. The main blade 17 is arranged inside the chute 12, which can improve the speed of air flow. The sealing cover 2 is arranged above the main blade 17 to prevent the main blade 17 from falling due to centrifugal force during rotation. Next, a heat sink 5 is arranged under the main fan frame 1, which can improve the heat dissipation speed. A copper tube protective cover 7 is arranged inside the heat sink 5, which can prevent corrosion and oxidation of the copper tube 4. The inside of the copper tube protective cover 7 The copper tube 4 is provided, which can speed up the transfer of heat. The outer wall of the copper tube 4 is provided with a heat-conducting block 3, which can quickly absorb heat. When the movement occurs, the auxiliary fan frame 9 is arranged below the heat sink 5, which can improve the heat dissipation on the surface of the heat sink 5. The interior of the auxiliary fan frame 9 is provided with a fixing hole 13, which can improve the firmness of the auxiliary fan frame 9.
