Abstract
The utility model relates to the technical field of radiating devices, in particular to a rotary fan structure, which comprises an installing base, a fan support arranged on the installing base and a fan connected with the bottom of the fan support in rotary mode. Outer threads are arranged on the installing base, inner threads matched with the outer threads are arranged on the fan support, and the fan support is fixed on the installing base in threading mode. When the fan is dedusted, users only need to rotate the fan support to separate the fan support from the installing base directly, and dedusting can be conducted for the fan in the fan support. After dedusting, the users only need to fix the fan support on the installing base in threading mode. The whole dedusting operation process is simple and convenient, time-saving and effortless and compact in structural design and can effectively guarantee service life of the radiating device.
Description
Technical field:
The utility model relates to the heat abstractor technical field, relates in particular to a kind of rotary fan structure.
Background technology:
At present; Computer fittings such as the central processing unit on the computer, video card are as high-end electronic product; It can produce great amount of heat in running, if can not in time distribute the heat that accumulates on these computer fittings, reduce its temperature; Then can directly influence its normal operation and useful life, so on computer fittings such as central processing unit, video card, generally be provided with heat abstractor.And existing heat abstractor mainly comprises body, is arranged on fin and the fan that is positioned at the fin top on the body, and fan is easy to produce dust in operation; Influence the radiating effect of heat abstractor, need carry out dedusting to fan usually, because existing heat abstractor is more single; Need the entire heat dissipation device be dismantled during dedusting; Demounting procedure is cumbersome, and dedusting is inconvenient, and can't be guaranteed the useful life of heat abstractor.
The utility model content:
The purpose of the utility model is exactly the rotary fan structure that a kind of good dedusting effect is provided to the deficiency of prior art existence.
To achieve these goals, the technical scheme of the utility model employing is:
The rotary fan structure; Include mount pad, be arranged on blower tray on the mount pad, be rotatably connected on the fan of blower tray bottom; Said mount pad is provided with external screw thread, and blower tray is provided with the internal thread that cooperates with external screw thread, and blower tray screws togather and is fixed on the mount pad.
Convex with at least one installation base of hollow on the said mount pad, external screw thread is located at the circumferential outer surface of installation base, and fan is positioned at installation base.
Said fan and installation base are two, and two installation bases are set up in parallel on mount pad, and two fans are separately positioned in the installation base.
Said blower tray includes body and evenly is arranged on a plurality of wheel hubs on the body, and fan is rotatably connected on the bottom of body, and body is connected fixing with an end of wheel hub, and internal thread is arranged on the other end inboard of wheel hub.
Said wheel hub has three.
Said body and a plurality of wheel hub structure that is formed in one.
Said mount pad is connected with cooling base.
The utility model beneficial effect is: the utility model includes mount pad, be arranged on blower tray on the mount pad, be rotatably connected on the fan of blower tray bottom; Said mount pad is provided with external screw thread, and blower tray is provided with the internal thread that cooperates with external screw thread, and blower tray screws togather and is fixed on the mount pad; When fan is carried out dedusting; Only need to make blower tray and mount pad directly separate, just can carry out dedusting work, after dedusting finishes the fan in the blower tray through the rotary fan support; Blower tray screwed togather to be fixed on the mount pad get final product; Whole dust removal operation process is simple and convenient, time saving and energy saving, and structural design is compact, effectively guarantees the useful life of heat abstractor.
Description of drawings:
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the decomposing schematic representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See shown in Fig. 1～2, the rotary fan structure, it includes mount pad 1, be arranged on blower tray 2 on the mount pad 1, be rotatably connected on the fan 3 of blower tray 2 bottoms; Mount pad 1 is connected with cooling base 4; Mount pad 1 is provided with external screw thread 11, and blower tray 2 is provided with the internal thread 21 that cooperates with external screw thread 11, and blower tray 2 screws togather and is fixed on the mount pad 1.
Wherein, convex with at least one installation base 12 of hollow on the mount pad 1, external screw thread 11 is located at the circumferential outer surface of installation base 12, and fan 3 is positioned at installation base 12.In the present embodiment, fan 3 is two with installation base 12, and two installation bases 12 are set up in parallel on mount pad 1; Two fans 3 are separately positioned in the installation base 12; So form double fan 3 structures, more can to greatest extent unnecessary heat be taken away, radiating effect is better.。
This blower tray 2 includes body 22 and evenly is arranged on a plurality of wheel hubs 23 on the body 22, and fan 3 is rotatably connected on the bottom of body 22, and body 22 is connected fixing with an end of wheel hub 23, and internal thread 21 is arranged on the other end inboard of wheel hub 23.The body 22 of blower tray 2 and a plurality of wheel hubs 23 structure that is formed in one.In this enforcement, wheel hub 23 has three, and each wheel hub 23 is the arc shape structure, and is attractive in appearance and water conservancy diversion is effective, and certainly, it also can be other shape and structures, not to exceed.
When fan 3 is carried out dedusting; Only need to make blower tray 2 and mount pad 1 directly separate, just can carry out dedusting work, after dedusting finishes the fan in the blower tray 23 through rotary fan support 2; Blower tray 2 screwed togather to be fixed on the mount pad 1 get final product; Whole dust removal operation process is simple and convenient, time saving and energy saving, and structural design is compact, effectively guarantees the useful life of heat abstractor.
Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
