Description

fan mount

technical field

The utility model relates to a fan fixing device, in particular to a fan fixing device which utilizes the relative displacement between the mushroom column and the gourd hole to enable the fan to be quickly positioned on the chassis.

Background technique

No matter what kind of electronic equipment or computer equipment, they will encounter the same problem when they are turned on and running, that is, heat dissipation. Moreover, as humans pursue the convenience of use, the necessary functions and achievable performance of the equipment itself are gradually improved. In contrast, the internal functional circuits of electronic components such as processing chips contained in the equipment chassis increase, resulting in the breakdown of electronic components. The relative increase in power consumption and heating power makes the temperature inside the chassis gradually rise. However, excessive temperature will affect the normal operation of the electronic components, and if it is more serious, it may cause the electronic components to burn out. Therefore, how to maintain a stable temperature inside the chassis has become a common issue in the industry.

However, in order to solve the problem of heat dissipation, usually the industry will install a heat dissipation fan at the air vent of the chassis or the place where the heat energy is generated, so as to force the air convection to discharge the hot air out of the chassis. As far as the prior art is concerned, the methods used to fix the cooling fan on the chassis are nothing more than the following:

(1) Fix the fan directly to the chassis by screwing. In this method, a plurality of corresponding screw holes are respectively provided on the fan and the case, and then the fan is tightly fitted and fixed on the case by using a plurality of screws in a threaded manner. In addition, screw caps can be added to assist in screwing, and fan support frames can be added to assist in the positioning of the fan, so as to prevent the chassis from loosening the screws or displacing the fan due to collision.

(2) Use the fixing device to assist the fan to be fixed on the chassis. In this method, ribs or plastic plates are used to make a frame that can encircle the fan, or to form a housing that can accommodate the fan, and a plurality of fastening bolts or clasps are arranged around the frame or the housing, and are attached to the chassis. Corresponding buckle holes or sockets are provided on the top for buckle bolts or hooks to fasten, so that the fan can be fixed on the chassis by the fixing device. However, in addition to the fastening method, there are also fixing devices that are fixed on the chassis by screwing, and corresponding screw holes are provided on the fixing device and the chassis, and then screwed to fix the device on the chassis.

But the existing technology has the following unavoidable drawbacks including:

(1) Not easy to replace. If screwing is used to fix the fan, whether the fan itself or the fixing device is installed or disassembled, it is necessary to use auxiliary tools, such as a screwdriver or wrench, to screw or turn the fixing screws. In the event of a fan failure, disassembly to replace a new fan is not possible without the tools. Secondly, in terms of fastening structure, the clasp is usually fastened on the buckle hole with a barb-like fastening, and it usually needs to be assisted by an additional tool when removing it. If the method is incorrect, the fastening structure will be damaged.

(2) Assembly parts are complicated. Regardless of screwing or buckling, installing a single fan or using an auxiliary fan positioning fixture requires multiple parts for fixing operations. For screwing, multiple screws and screw caps are required, and it depends on the situation. Parts such as fan support brackets or outer frame covers may also be needed to assist in positioning. It takes a lot of time just to identify the function of the parts, let alone assemble the various parts. In addition, if one less part is installed, the amount of fixed fan may not be enough to cause displacement.

Utility model content

In order to achieve the above object, the utility model provides a fan fixing device, which clamps at least one fan and fixes the fan firmly in a case. The fan fixing device includes a plurality of mushroom posts and a frame. Each mushroom column is divided into two parts: the mushroom head and the mushroom column, and the outer diameter of the mushroom head is larger than the outer diameter of the mushroom column. The frame itself has a clamping part and multiple gourd holes. The clamping part is used to clamp the fan in the frame, and the positions of the gourd holes correspond to the mushroom columns. The gourd hole itself is divided into three parts, which are the introduction part and the positioning part. And the slide rail, the slide rail is used to connect the introduction part and the positioning part, and the aperture of the introduction part is larger than the outer diameter of the mushroom head. When the frame is being positioned, all the mushroom columns are accurately matched to each gourd hole and inserted into its introduction part, and then the mushroom columns are moved to the positioning part through the slide rail, and finally stop and positioned at the positioning part, and the frame will also be accordingly. The state of positioning is formed.

Secondly, in order to enhance the positioning effect of the fan fixing device, a set of engaging modules can be added to the whole set of devices, an abutting block is provided on the chassis, and an engaging piece is provided on the surface of the frame facing the abutting block. When the frame completes the positioning action, the engaging member and the abutting block are engaged to form a force to keep the mushroom column positioned at the positioning part, thereby enhancing the positioning effect of the frame.

Compared with the prior art, the fan fixing device provided by the utility model has the following excellent functions and capabilities:

(1) Fan replacement is easier and more convenient. The prior art uses screwing or buckling for fixing, and often requires the use of auxiliary tools, such as a screwdriver for screw locking, so that the installation or disassembly of the fan is very time-consuming and laborious; however, using this The fan fixing device of the utility model only needs to insert the mushroom column into the gourd hole, and then move to the positioning part to complete the positioning of the frame body. A snap-on module can also be added to maintain the positioning of the mushroom column through the force generated by the clip. Compared with the prior art, it is much more convenient.

(2) Save time and cost. When fixing the fan in the prior art, it is often necessary to install additional parts, such as a fan support frame or an outer frame cover to assist in fixing the fan; however, the fan fixing device of the present invention does not need to assemble complicated components, and the components it has Functions can be easily seen from the appearance and can be positioned. Even if a snap-on module is added, only one more snap-in action is required, and the fan fixing device can complete the positioning, which greatly saves the time for users to identify the functions of components and assemble them.
