Description

fan holder

【Technical field】

The utility model relates to a fan fixing frame with simple structure, convenient assembly and disassembly, and good heat dissipation effect.

【Prior technology】

The main heat sources in a personal computer are the central processing unit on the motherboard and the power supply in the computer case. Usually, the heat generated by the central processing unit is discharged by installing a radiator on the central processing unit and a fan on the radiator. In addition, a fan is also installed in the power supply to dissipate the heat generated by it. With the continuous development of the computer industry, the high frequency and high power of computers have brought new problems to heat dissipation. Therefore, in order to achieve a better heat dissipation effect, an independently operated fan is installed on the computer casing to suck in cooling air from the outside of the computer casing, and cooperate with the fan of the power supply to generate convection in the computer casing. The installation and fixation between the fan and the inside of the computer casing is achieved by installing a fan fixing frame in the computer casing, and then fixing the fan on the fan fixing frame. However, in this fixing method, screws are often used to lock the fan on the fan fixing frame and the fan fixing frame is locked on the computer casing with screws, which brings a lot of inconvenience to assembly and disassembly.

With the continuous development of technology, screwless fan fixing devices have appeared, such as the fan fixing device disclosed in Chinese Patent Application No. 01201836.8. The fan fixing device includes a fan frame, the fan frame is fixed on the chassis board, and a fan is fixedly installed on the fan frame, and a hook protrudes from the side of the fan frame facing the chassis board, and the position is set on the upper frame. Tongue pieces protrude from the side of the fan frame towards the fan with a baffle, a small hook and a large hook respectively. The left and right edges of the fan frame of the fan are stuck between the baffles, and the lower edge It is clamped by the small hook, and the upper side edge is clamped by the large hook. The fan fixing device clamps the fan through large and small hooks and baffles, which makes the structure of the fan fixing device complicated. In addition, the fan is installed on the outside of the fan frame, so that the fan is not closely attached to the chassis board but blows air through the thickness of the fan frame, so that the heat dissipation effect is not very good.

【Content of invention】

The purpose of the utility model is to provide a fan fixing frame with simple structure, easy disassembly and good heat dissipation effect.

The utility model is used to fix a fan and install it on a computer casing, comprising a main body, a top wall, a bottom wall and two side walls, the top wall and the bottom wall are a group of fans from the main body The opposite edges are extended, the two side walls are formed by extending from another set of opposite edges of the main body, the fan fixing frame forms a receiving space, four corners of the fan are respectively provided with a fixing hole, and the main body protrudes from a plurality of pairs of According to the elastic fixing pin of the fan fixing hole, the outer edges of the top wall and the bottom wall respectively form a first clasp and a second clasp, and the side wall extends toward the top wall to form a pressing part. A pair of buckle blocks are protruded from the front end, and the computer case is provided with a ventilation hole area, and the periphery of the ventilation hole area is correspondingly provided with a button hole that can be buckled with the buckle hook and the buckle block of the fan fixing frame, and the fan is fixed on the The fan fixing bracket is in the accommodation space and can be closely attached to the computer casing.

The fan fixing frame of the utility model adopts a screwless structure to fix the fan on the fan fixing frame and assemble it on the computer casing, which is not only simple in structure but also convenient to assemble and disassemble. In addition, the fan fixing frame can make the fan closely adhere to the computer casing for air supply, so that the heat dissipation effect is better.
