Abstract
The utility model relates to a circular fan for a CPU radiator. The utility model comprises a base of a motor of the fan, blades, a conducting wire, a frame of the fan, frame ears, positioning holes and a connecting rib. The specific structure and the connecting relation of the utility model are as follows: the frame of the fan is circular, the center of one side of the frame of the fan is provided with the base of the motor, the base is provided with the motor, and the motor drives the blades to rotate; in addition, the eight symmetrical frame ears are uniformly arranged on the circumferential surface at both sides of the frame of the fan, the positioning hole is arranged on each frame ear and is used for connecting heat radiating fins (a cover of the fan), and the positioning hole can also be connected with an air deflection cover. The fan is suitable for various kinds of CPU radiators. The utility model has the maximum characteristics that in the past, a frame of a fan is square, and the frame of the fan of the utility model is circular; in the past, the size of a blade is small, and the size of the blade of the utility model is big; the integral size of the fan is not changed, the ventilated area of the fan is enlarged and the heat radiating efficiency is improved.
Description
Technical field
The utility model relates to cpu heat, mainly is meant a kind of Circular fan that is used for cpu heat.
Background technology
Fan is one of main heat radiation instrument, and range of application is very wide, also is the same in computing machine, and fan is playing an important role.In the mainframe box of computing machine, CPU (central processing unit) is maximum heater members (power reaches about 100 watts), thus need dispose heating radiator to CPU, so that dispel the heat effectively.In heating radiator, the effect of fan is exactly that the heat that heat radiator absorbs is taken away by flow air.Because be subjected to the restriction of chassis space, the framework of known fan all is square, this diminishes with regard to the circle diameter that makes flabellum, influences wind-force and air quantity.In addition, the flabellum size of said fans is less, and quantity is more, and this also influences wind-force, and finally influences radiating effect.If want to increase fan dimension, will be subjected to the restriction in space, so improve the structure and the shape of existing fan, making it to improve radiating efficiency is a kind of valid approach.
Summary of the invention
The purpose of this utility model is intended to overcome the defective that existing cpu heat fan exists, and proposes a kind of Circular fan of cpu heat.
The realization the technical solution of the utility model is: the primary structure of heating radiator comprises heat-conducting cream, heat radiator, fan and fastener; And the improvement part of fan that to be fan frame be is circular, and be provided with the frame ear that connects fan cover and wind scooper respectively at the end face of circular frame, on this frame ear pilot hole is arranged.
This technical scheme also comprises:
End face center at fan frame is provided with the fan electromotor base, and this base is fixed on the fan frame by dowel.With
Both ends of the surface at fan frame are provided with uniform, symmetrical frame ear.With
The flabellum of fan is 5-7, and the width of this flabellum is 4/3-2 a times of traditional flabellum width.With
On dowel, be provided with the groove of putting the motor lead.With
Be provided with the frame ear of 8 symmetries altogether in the both ends of the surface of fan frame.
The utlity model has following advantage:
1. under the situation that does not change original installation dimension, increased the size of fan.
2. increase ventilation, improved radiating effect.
3. adaptive various heat radiator, versatility is good.
Description of drawings
Fig. 1 is a general structure schematic perspective view of the present utility model, wherein 1 fan electromotor base, 2 flabellums, 3 leads, 4 fan frames, 5 frame ears, 6 pilot holes.
Fig. 2 be the A of Fig. 1 to view, the bottom surface of expression fan frame, wherein 7 dowels, 8 grooves.
Fig. 3 is the synoptic diagram that the utility model and heat radiator are fixed together, wherein 9 heat radiator, 10 bases, 11 fasteners.
Embodiment
The utility model is mainly used on the cpu heat, is one of critical piece of cpu heat, and the fan after improving can better be brought into play thermolysis, increases work efficiency.The structure of this fan is, one, fan frame is circular; Two, the flabellum of fan becomes dimensionally greatly, quantitatively reduces.In addition, on fan frame, be provided with the frame ear that connects fan cover and wind scooper.This fan can make fan become big under the situation that does not increase former installation dimension and structure, has reached the purpose that increases air quantity.
Embodiment
This fan comprises fan electromotor base 1, flabellum 2, lead 3, fan frame 4, frame ear 5, pilot hole 6 and dowel 7.Its concrete structure and annexation are: fan electromotor base 1 is fixed on the center of Circular fan framework 4 one sides by dowel 7, on motor base 1 motor is installed, and driven by motor flabellum 2 rotates, and flabellum has 7; In addition, the frame ear 5 of uniform 8 symmetries (shape of frame ear is a triangle) on the periphery of the both sides of fan frame 4, wherein each side is 4, and on each frame ear, pilot hole 6 is arranged, the frame ear is in the outside of fan frame 4 peripheries, its effect is to connect heat radiator (fan cover) 9, also can connect wind scooper.When fan connected heat radiator (fan cover), the reference column on the heat radiator support was inserted in the pilot hole 6 of frame ear 5, and the claw on the fan cover just is stuck on the limit of frame ear 5.In addition, the gap that passes on 5 jiaos in groove 8 on the dowel 7 and the frame ear of the lead 3 of fan electromotor meets CPU by terminal.This fan is applicable to various types of cpu heats, it is compared with the fan that was used in cpu heat in the past, maximum characteristics are to be changed into the Circular fan framework and changed undersized flabellum into large-sized flabellum by square fan frame, realized under the situation that does not change the fan overall dimensions, increase the draught area of fan, improved radiating efficiency.
