Description

fan holder

technical field

The invention relates to a fan fixing frame, in particular to a fan fixing frame for fixing at least one cooling fan in an electronic device.

Background technique

With the rapid development of electronic technology, and in order to meet consumers' requirements for data processing speed, the calculation speed of electronic components inside computer devices must be accelerated. If the heat energy cannot be dissipated in a timely manner, the high temperature will seriously affect the stability and efficiency of the electronic components during operation, shorten the service life of the computer device, and even cause damage.

In order to quickly dissipate the heat generated by the electronic components, the existing heat dissipation method installs a cooling fan inside the computer device to blow a forced airflow to the high-energy electronic components to dissipate heat and reduce the ambient temperature inside the computer device.

The four corners of the existing cooling fan are respectively provided with a fixing hole, through which locking members such as bolts pass through the fixing hole, and the cooling fan is locked on the computer case; A frame on the case to keep the fans in place for cooling.

However, when assembling or repairing the cooling fan, the user must repeatedly install and disassemble the bolts or the frame, which is a time-consuming and complicated process, and when the cooling fan needs to be repaired and replaced, the operation of the computer device must be stopped and the whole machine must be disassembled. It is not convenient to replace.

At the same time, the size of the existing fan frame is mostly only suitable for a specific fan model. If you want to replace a cooling fan with a different size, you must reconfigure the matching frame. Moreover, the size of the frame is too large. If multiple frames are installed and used at the same time, it will greatly occupy the space inside the computer device, which is not in line with the current development trend of the computer device being light, thin and small.

Furthermore, in order to have a certain structural strength, the fan frame is mostly made of rigid materials, and the cooling fan is fixed directly in contact with the frame. The vibration energy generated by the fan during operation can easily interact with the frame to generate resonance , coupled with the resonance frequency of the internal space of the computer device, the resulting resonance noise is very serious. Moreover, the fan is likely to collide due to the resonance between the frames, thereby shortening the service life of the fan.

Contents of the invention

The purpose of the present invention is to provide a fan fixing frame to improve the complicated mounting and dismounting process of the heat dissipation fan in the prior art, the size and specification between the fan and the frame do not match, and the frame has no shockproof design, resulting in high manufacturing cost, insufficient holding stability, And problems such as excessive noise generated during operation.

In order to achieve the above object, the present invention discloses a fan fixing frame for fixing at least one cooling fan on the casing of an electronic device. The fan fixing frame includes a frame and at least one positioning member. Wherein, the frame has two boards, which are arranged opposite to each other at a distance, one side of one board has a joint portion, and one side of the other board has a locking portion, so that the frame partitions at least one accommodating area , for the cooling fan to be accommodated therein, and the locking part and the joint part are combined with each other to form a clamping area. The positioning part is fixed on the casing and sandwiched in the clamping area so that the frame is fixed on the casing.

The beneficial effect of the present invention is that, the fan fixing bracket separates the accommodating area and the clamping area through the joint part and the locking part, so that the cooling fan can be accommodated and fixed in the frame, and the frame can be connected with the positioning part through the clamping area. The clamping and fixing between the cooling fans makes the cooling fan directly fixed on the casing, so as to greatly save the time and steps of assembling and disassembling the cooling fan.

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
