Conveniently mounted magnetic attached cooling fan structure

The present invention relates to a heat dissipating fan structure, in particular to a magnetic package with elastic material to achieve direct magnetic attraction to a metal casing, which is convenient for installation and at the same time achieves shock absorption and noise reduction. Attached cooling fan structure.

In order to make the heat generated by the electronic components in the electronic device operate smoothly, the cooling fan is set as an indispensable device, and for the convenience of installation and the number of cooling fans can be easily increased, many cooling fans are now changed to magnetic The design can be directly magnetically attached to the metal casing, but the conventional magnetically attached cooling fan has many disadvantages due to poor design.

The patent of the Taiwan Patent No. M316940, which is shown in Fig. 1, wherein the magnetic component is designed to be fixed through the through hole 61 provided in the fan body 6 through the rod body 51 provided on the main body 5, and the main body 5 is fixed. The front end is provided with a magnetic element 53. The elastic body member 52 can be sleeved on the rod body 51 to absorb the vibration generated by the fan body 6 during rotation and enlarge the rod diameter to be pressed into the through hole 61. Positioning, but since the fixing point of the magnetic element 53 and the fan body 6 is only the portion of the rod body 51, when the fan body 6 is magnetically operated on the metal casing, the magnetic attached fan structure is still extremely easy to shake, and The magnetic element 53 is too small and the magnetic force is insufficient, and the entire magnetically attached fan structure is displaced on the metal casing; and if the direction of the intake and exhaust of the cooling fan is to be changed, the magnetic component needs to be disassembled and installed on the fan body. On one end face, the rod body 51 is fixed only by pressing into the perforation 61, which means that it is difficult to disassemble to be disassembled, which is inconvenient in use.

In addition, the patent of Taiwan Patent No. M426986 shown in Fig. 2, the design of the suction-type fixed base 7 and the tapered portion of the fastening rod 71 and the fixing rod 71 enlarge the rod diameter, and the fixing base 7 is also fixed. After the rod 71 is installed in the through hole 81 of the fan body 8, it is difficult to disassemble, and At the fixed point with the fan body 8, there is only a portion of the fixed rod 71, so that the lack of unstable sway is still generated when the fan body 8 is operated.

In the above configuration, the sector fixing member is a rib provided on an end surface of the side of the fan body in a vertical direction.

In the above configuration, the sector fixing member is a rib provided on an end surface of the side of the fan body in a horizontal direction.

In the above configuration, the magnetic attachment fixing member is a groove that is fixed corresponding to the sector fixing member.

In the above configuration, the sector fixing member is a screw hole, and the magnetic attachment member is composed of a through hole and a screw. In this way, after the magnetic attachment component is mounted on the fan body, the magnet can be inserted through the through hole of the magnetic component and the fan fixing member (threaded hole) on the fan body. The fan body is locked to form a more stable effect.
