Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a fan module, and in particular, to a fan module suitable for being disposed inside a portable device for The hot air inside the device is discharged to the external fan module. [Previous technology] In recent years, with the rapid advancement of computer technology, the computer's operating speed has been continuously improved, which has continuously increased the heating power of electronic components inside the computer mainframe. A temporary or permanent failure occurs, so the heat dissipation performance of the electronic components inside the computer becomes very important. Therefore, in addition to the power supply of the host computer, the central processing unit (CPU) and the graphics processing unit (GPU), and even the electronic components that easily increase the temperature, such as a chipset, an additional cooling system is additionally installed. In order to reduce the temperature of electronic components at high speed, a fan module can be installed inside the host computer to generate thermal convection inside and outside the host computer, so that the host computer can operate more smoothly. . It is worth noting that because the internal space of a notebook computer is very small, the thermal energy generated by its electronic components can easily accumulate in the gas inside the notebook computer, so the conventional technology usually installs a The fan module is used to discharge the internal heat of the notebook computer to the outside for the purpose of heat dissipation. Please refer to FIG. 1, which shows a perspective view of a conventional fan module. A fan module 100 commonly used in notebook computers generally includes

Therefore, when the fan module 100 is applied to a cooling system of a notebook computer, the fan module 100 can effectively discharge the internal heat of the notebook computer to the outside world, so that the notebook computer can operate more smoothly. As far as the conventional technology is concerned, the air outlet 116 of the fan module 100 is not currently provided with any grid. Therefore, 'When the fan module 100 is arranged inside a notebook computer, the maximum outer diameter of the user during carrying or carrying the notebook computer is smaller than the small conductive objects of the air inlet 11 4 and the air outlet 116. (Such as paper clips or staples, etc.) can easily pass through the air outlet 116, the accommodation space 112, and the air inlet 114 of the casing 1 10 in order to enter the interior of the notebook computer and touch the notebook computer. The internal electrical contacts or circuits may cause the internal circuit of the notebook computer to fail. Therefore, in order to reduce the possibility of the above-mentioned small conductive objects entering the interior of the notebook computer, in the current safety regulations for portable devices, the narrow and long position is located on the surface of the portable device and can communicate with the interior of the portable device. The width of the opening will be limited to 1 mm.
