The motor drives the fan blade to rotate under the action of the PCB board to provide air flow for heat dissipation. The fan housing structure 1 of the present application has a receiving cavity 3 for accommodating the fan main machine 2.

[0033] The first embodiment of the fan housing structure 1 of the present application and Figure 1 - Figure 5 the second embodiment of the fan housing structure 1 of the present application will be described below. Figure 6 -Figure 11 The second embodiment of the fan housing structure 1 of the present application is further described in detail.

[0034] As shown in the drawings, Figure 1 - Figure 5 The fan housing structure 1 of the present application comprises a fan bracket 11 having a receiving cavity 3 for receiving a fan main machine 2, a back cover 12 and a plurality of locking ears 13. The receiving cavity 3 of the present application has a back opening 31, and the back cover 12 of the present application is arranged on the fan bracket 11 and covers the back opening 31. In order to facilitate assembly and maintenance, specifically, the back cover 12 of the present application is detachably clamped on the fan bracket 1 and covers the back opening 31 in a flush or sunken manner. Further, Figure 2 The embodiment of the back cover 12 covering the back opening 31 in a flush manner 121 is given, that is, the upper end surface of the back cover 12 is flush with the upper end surface of the fan bracket 11. If the sunken manner is adopted for installation, the back cover 12 of the present application is sunken by 1 mm relative to the fan bracket 11, that is, the upper end surface of the back cover 12 is 1 mm lower than the upper end surface of the fan bracket 11. The inner side wall 111 of the fan bracket 11 is provided with a horizontal sliding groove 4, and the outer side wall 112 of the fan bracket 11 is provided with a sliding opening 5 communicating with the sliding groove 4.

When the fan 100 having the fan housing structure 1 of the present application is installed, the sliding part 131 of the locking ear 13 is slid in the sliding groove 4 of the fan bracket 11 by operating the fixing part 133. At the same time, the arc-shaped connecting part 132 is in arc-shaped contact with the sliding opening 5, which effectively reduces the friction of the connecting part 132 at the sliding opening and improves the smoothness of the sliding of the locking ear 13. The locking ear 13 slides until the fixing hole 134 of the fixing part 133 is aligned with the locking hole position of the carrier of the electronic equipment to which it is attached, and then a screw is sequentially passed through the fixing hole 133 and the locking hole of the carrier and tightened, so that the fan of the present application is fixed on the electronic equipment. As can be seen, the sliding locking ear 13 is arranged on the fan bracket 11, so that the position of the fixing hole 134 of the locking ear 13 can be adjusted to be consistent with the position of the locking hole of the carrier to which it is attached according to the actual installation and fixing requirements of the fan 100, so that the fan housing structure 1 and the fan 100 of the present application are suitable for assembly in various electronic equipment. The structure design of the present application is reasonable, simple and practical, and can effectively improve the production speed and reduce the cost.

[0035] As shown in the drawings, Figure 1 , Figure 2 , Figure 6And Figure 9 As shown in the figure, the fan bracket 11 of the fan casing structure 1 of the present application has a protruding clamping protrusion 113. The rear cover 12 of the present application has a clamping opening 122 corresponding to the clamping protrusion 113, which is detachably connected with the clamping protrusion 113. When assembling the fan 100 of the present application, first, the fan main body 2 is installed in the receiving cavity 3 of the fan bracket 11, and then the rear cover 12 of the present application is covered at the rear opening 31 and the clamping protrusion 113 is inserted into the clamping opening 122, so that the fan bracket 11 and the rear cover 12 of the present application are detachably connected by the clamping of the clamping protrusion 113 and the clamping opening 122, and the rear cover 12 covers the rear opening 31. Further, the rear cover 12 of the present application is an iron component.

[0036] As shown in the figure, Figure 1 - Figure 8 As shown in the figure, the fan bracket 11 of the fan casing structure 1 of the present application has a protruding inner bearing 114, which is parallel to the inner side wall 11 of the fan bracket 11, and the gap between the inner side wall 111 and the inner bearing 114 forms the sliding groove 4. The sliding groove 4 for the locking lug 13 is formed by the gap between the protruding inner bearing 114 and the inner side wall 11 of the fan bracket 11, so that the sliding groove 4 is formed by two plate-shaped bodies, which is simple in structure and easy to use; effectively avoiding the complex process of opening a groove on the fan bracket 11 to form the sliding groove 4. Further, in order to better realize that the rear cover 12 of the present application is detachably clamped on the fan bracket 1 and covers the rear opening 31 flush or sunken, the clamping protrusion 113 of the fan casing structure 1 of the present application is arranged on the inner bearing 114.
