Description

Radiation fan

The utility model is the radiation fan that improves structure about a kind of, particularly at being installed on the various electronic heating device innovative design of getting rid of high temperature for heat radiation and itself attaching a kind of radiation fan of safety guard net.

The running that arrives and be enough to self-destruction or damage other abutment means or element because the accumulation of the variation of voltage or circuit all can make some electronic equipment or element be easy to produce high temperature in general host computer or other electrical appliance, all can set up radiator so those are easily given birth on the electronic equipment of high temperature or the element, and the radiator of normal use is radiation fan.

Be a kind of traditional heat-dissipating fan 1 as shown in Figure 1, its structure consists essentially of the fan pedestal 10 that plastic cement material makes and is hubbed on the flabellum body 11 that rotates on the fan pedestal, and flabellum body 11 only utilizes the ribs 12 of a side to be connected with 10 of fan pedestals and supports flabellum body 11 stator positions, but the another side then is completed into hollow out and makes the air free flow, only so will produce the problem in the binomial practicality at least: the one problem is that flabellum body 11 lacks suitable protective net structure for preventing to point or the intrusion of other foreign matter thereby injured or impaired, so be equiped with itself must to prepare on the electronic equipment of this radiation fan 1 protective net or similar protective construction (for example the power supply unit of host computer is an example) arranged, so often cause the puzzlement in the use, generally in a single day the protective net that may not reckon with or make in advance same size because of each manufacturer of dealer's system electronic equipment cooperatively interacts with it, can't not reach predetermined protection effect so have when the design of this protecting wire net or size are inconsistent; Its two problem is not have protecting wire net and the radiation fan 1 of hollow out will produce EMI (electromagneticinterference) penetration to the electronic equipment of periphery, so in case this radiation fan 1 is installed in nothing when preparing on the electronic equipment that protecting wire net is arranged in advance, may produce electromagnetic interference to peripheral electronic equipment, in fact can not be accidentally and the plot solution.

So in view of this, this case creator is long-pending be engaged in computer hardware and relevant spare part product professional development and production and marketing experience for many years, several times trial-production is done with real, can develop a kind of radiation fan that itself to attach the metal protecting wire net eventually.

At the shortcoming of prior art, main purpose of the present utility model is to provide a kind of and is installed with the radiation fan of metal protecting wire net at it.

The purpose of this utility model can realize by following mode, the utility model includes the fan pedestal and the flabellum body of plastic cement system, it is characterized in that: fan pedestal one is embedded and is fixed with the metal protecting wire net, and the metal protecting wire net can be inserted in advance in the mould and be fixed with plastic cement fan pedestal one ejection formation; Fan pedestal four corners are provided with perforation, and metal protecting wire net four corners are provided with corresponding with it positioning hole simultaneously; Or metal protecting wire net four corners respectively are provided with the chucking lug of protrusion, and respectively are provided with a positioning hole on each chucking lug; Promptly, make radiation fan itself both set up the metal protecting wire net in advance, being useful in widely with energy supply variously has protecting wire net or does not have on the electronic equipment of protecting wire net, and simultaneously can reach preferable EMI effect of control and promote practicability and convenience, and metal protecting wire net four corners respectively convex with the pre-buried chucking lug of metal of tool positioning hole again for the screw interlocking, so more can add strong wind fan locking force amount.

For enabling further to understand the utility model is to reach technology, means and the effect that predetermined purpose is taked, now describe in detail for a preferable feasible embodiment and conjunction with figs. as after, think letter the purpose of this utility model, feature and advantage when can be thus one go deep into and concrete understanding.
