Abstract
The utility model relates to the technical field of computer fans, particularly to a computer graphic card fan. The computer graphic card fan comprises a base with the center in a hollow structure, a rotating shaft is arranged inside the base, a double-ball bearing is arranged between the base and the rotating shaft, a sealing ring is arranged above the double-ball bearing, and a retaining ring is arranged under the double-ball bearing; a fan blade frame with blades is arranged above the base, and the rotating shaft is fixedly connected with the fan blade frame; a motor is arranged under the rotating shaft and inside the base and connected with wires extending out of the base. The computer graphic card fan is simple in structure and reasonable in design, by means of the double-ball bearing, is wearing-resistant and long in service life, and by means of the sealing ring and the retaining ring for dust prevention, achieves good heat dissipating performance.
Description
Technical field
The utility model relates to computer electric fan technical field, especially a kind of computer display card fan.
Background technique
The loom of Internet bar is almost to open for 24 hours, and do not possess good ventilated environment, dust is also many, so to having brought great test the life of equipment of cabinet inside, there is no the environment of good ventilation, the temperature rise of cabinet inside, inner hardware is also to rise with the temperature of environment thereupon, dust is also hardware killer, if stood covered in dust on radiator, heat radiation be can be described as and is had a greatly reduced quality.If the oil-impregnated bearing that radiator fan adopts, owing to containing lubricant oil, the time has been grown oily can volatilization, dust also can enter bearing the inside, causes rotation speed of the fan slack-off, and bearing wear causes the eccentric strenuous vibration that causes of fan, serious also can cause fan stall, video card DIE Temperature is too high and burn.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, long service life, good heat dissipation effect and dustproof computer display card fan.
The utility model solves the technological scheme that its technical problem adopts: a kind of computer display card fan, there is the pedestal that center is hollow structure, described pedestal is built-in with running shaft, between pedestal and running shaft, be provided with two ball bearings, described pair of ball bearing top is provided with seal ring, and two ball bearings below is provided with clasp; Described pedestal top is provided with the flabellum framework with flabellum, and running shaft is fixedly connected with flabellum framework; Described running shaft below is provided with motor, and motor is positioned at base interior, and motor is connected with the electric wire stretching out outside pedestal.
Further, described flabellum is positioned on the circumferential edges of flabellum framework, and flabellum and flabellum framework adopt PVC single injection-molded.
Further, described running shaft is flexibly connected with motor.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, are provided with two ball bearings, rub resistance, long service life; Be provided with seal ring and clasp for dustproof, there is good heat dispersion simultaneously.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. pedestals in figure, 2. flabellum framework, 3. flabellum, 4. running shaft, 5. pair ball bearing, 6. seal ring, 10. electric wire, 8. clasp, 9. motor.
Embodiment
Computer display card fan as shown in Figure 1, having center is the pedestal 1 of hollow structure, and pedestal 1 is built-in with running shaft 4, is provided with two ball bearings 5 between pedestal 1 and running shaft 4, and two ball bearings 5 tops are provided with seal ring 6, and two ball bearings 5 belows are provided with clasp 8; Pedestal 1 top is provided with the flabellum framework 2 with flabellum 3, and running shaft 4 is fixedly connected with flabellum framework 2; Running shaft 4 belows are provided with motor 9, and motor 9 is positioned at pedestal 1 inside, and motor 9 is connected with the electric wire 10 stretching out outside pedestal 1; Flabellum 3 is positioned on the circumferential edges of flabellum framework 2; Running shaft 4 is flexibly connected with motor 9.
When work, electric wire 10 is connected with power supply, and motor 9 task driven running shafts 4 rotate, and because running shaft 4 is fixedly connected with flabellum framework 2, thereby drives flabellum 3 to rotate, and the heat of video card is taken away, and reaches radiating effect.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art, all should fall in protection domain of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment according to design of the present utility model.
