In one embodiment, the fixing seat is a trapezoid table, a bottom surface of the trapezoid table is fixed on the case side plate, and the top surface of the trapezoid table is provided with the groove.

In one embodiment, the shape of the recess matches the profile of the fan.

In one embodiment, a first through hole is formed in the case side plate, a protrusion matched with the first through hole is formed in the fixing seat, and the fixing seat is fixed to the case side plate through the protrusion and the first through hole.

In one embodiment, a boss is arranged at the joint of the bottom of the fixed seat and the groove, and a predetermined distance is formed between the boss and the case side plate.

A fan module comprises a fan fixing device and a fan fixed on the fan fixing device, wherein the fan fixing device comprises a case side plate and a fixing seat fixed on the case side plate, a groove used for containing the fan is formed in the fixing seat, a preset distance is formed between the bottom of the groove and the case side plate, and an elastic element used for fixing the fan is arranged in the groove.

In one embodiment, the elastic element includes a positioning column and an elastic hook, the positioning column is located at an edge of the groove, the elastic hook is located at two sides of the groove, the fan is provided with a second through hole matched with the positioning column, the positioning hole extends into the second through hole, and the elastic hook is clamped at two sides of the fan to fix the fan on the fixing base.

According to the fan fixing device, the fixing seat is arranged on the case side plate, the groove for containing the fan is formed in the fixing seat, and a preset distance is formed between the bottom of the groove and the case side plate. Thereby, the effect of enlarging the radiating surface of the fan is achieved.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention can be embodied in many different forms than those herein described and many modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 3, a fan module 100 includes a fan fixing device 200 and a fan 30 fixed on the fan fixing device 200. The fan fixing device 200 includes a case side plate 10 and a fixing base 20 fixed on the case side plate 10. The fixing seat 20 is provided with a groove 11 for accommodating the fan 30, and a predetermined distance is formed between the bottom of the groove 11 and the case side plate 10. An elastic element 110 is arranged in the groove 11, and the fan 30 is fixed on the fixed seat 20 through the elastic element 110.
