Description

Heat abstractor

The utility model relates to a kind of heat abstractor that is applied to computer cpu (CPU), especially has the heat abstractor of high-speed computation processing capacity processor.Because high speed processor can produce high temperature in running, absorbed thermal source so must rely on the large tube-like radiator, and principal character of the present utility model is exactly will design a kind of and this tubular heat radiation physical efficiency to mate and do the fan group that the time spent can not disturb mutually, makes whole heat abstractor can bring into play the radiating effect of the best.

Because the job that computer is handled is increasingly sophisticated, speed also makes the working temperature of processor (CPU) increase sharply more and more soon, relatively, if heat dissipation problem does not achieve a solution, be to make the high main cause of functional processor performance, think the coupling high speed processor heat radiation, the dealer proposes the scheme improved one after another, in the K7 processor that is used in the exploitation of US business AMD recently, just has heat abstractor as shown in Figures 1 and 2 to come out.This class heat abstractor is called " power Cooler ", and the meaning is to have superpower radiating treatment effect.Can see from diagram: two kinds of heat abstractors all are that the radiator with a tubular serve as basic, dispose the fan group of two kinds of different types again, and purpose all is more, the thermal source faster of large-scale whereby heat radiation physical efficiency absorption, is dispelled via the fan group again.

The applicant does not have different suggestions for the above-mentioned thermal source that utilizes cartridge type radiator (Heat Sink) to draw heater, but, commonly use the fan group that heat abstractor sets at these two kinds different views is but arranged, think that these two kinds of fan structures and the mode that is fixed in radiator have necessity of improvement in fact, division is as follows:

One, as the disclosed heat abstractor of Fig. 1, this fan 10 directly is locked in the inner bottom surface of tubular radiator 12 by some screws 11, and the problem of its existence has:

1, fan base 13 very is close to bottom surface 16 (see figure 3)s of radiator 12, make the bottom surface (temperature highest point) of originally approaching most heater (CPU), (figure does not show to add driving element in the fan base 13, objects such as finger coil, pole piece) heat of being sent because of work produces heating effect, not only be helpless to heat radiation, increase thermal source on the contrary, cause radiating effect to be difficult to perform to optimum condition.

2, as shown in Figure 3, at location fan 10 in radiator 12 in the time,, cause being difficult to carry out with deeply the lock work of fan base 13 of instrument owing to being subjected to stopping of fan blade 14; Unless painstakingly strengthen the spacing between the fan blade 14, but can therefore reduce the area of blade, reduce the efficient of heat radiation on the contrary.

3, be Fig. 3 equally, the power lead 15 under the fan base approaches the bottom surface 16 (being the temperature higher position) of radiator equally, and causes the insulation of power lead 16 to be damaged easily, makes the fan can't normal operation.

Two, the heat abstractor of commonly seeing of another kind as shown in Figure 2 is the framework 22 fan attachment seats 23 that hang down and establish with a ring frame 21 belows, though improved the problem that aforementioned first kind of fan group is difficult to be positioned tubular radiator 20, as seen following shortcoming is arranged still:

1, the wind path that has directly stopped fan 24 owing to framework 22, the efficient that causes dispelling the heat reduces, and the effect of heat abstractor is given full play to.

2, fan base 23 still points to the bottom surface of tubular radiator 20, makes this kind design still produce the shortcoming of heating effect just like first kind of person of commonly using.

3, ring frame 11 is with gluing opening surface in radiator 20, so locating effect is very poor; High temperature is especially arranged, the predicament that can cause the fan group to drop the fixing glue fusion during this radiator 20.

Because above two kinds of same heat abstractors of tubular radiators that use all have important disadvantages like this, find out and crucial problem is very clear, all be because the design of fan group bad due to.

Fundamental purpose of the present utility model provides a kind of heat abstractor, makes flabellum after the driving element of inside drives running, can be directly with wind in radiator, and radiator absorbed the thermal source that comes from heater leave; So, allow the fan seat be away from the bottom surface of radiator, when making fan be subjected to driving element to drive running, the working temperature that is produced also can not interfere with radiator.

Another purpose of the present utility model provides a kind of heat abstractor, and without any obstruction, it is high that the efficient of fan is performed on the path of wind-guiding (or blowing) for fan, and then, increase the radiating effect of whole pack heat dissipation device.

Another purpose of the present utility model provides a kind of heat abstractor, and power lead also is away from the high temperature bottom surface of radiator, makes it not insulated by temperatures involved, and can provide normal power supply to fan, makes fan keep stable operating condition always.

A purpose more of the present utility model provides a kind of heat abstractor, provide one group of setting element to aforesaid ring frame, make this ring frame can be fixed on the opening surface of tubular radiator highly stablely, and mode fixing or dismounting simply is not subjected to any obstruction, so as to reducing the trouble of user at fit on.

The purpose of this utility model is achieved in that a kind of heat abstractor, comprise a tubular radiator, and one be fixed in the fan group of tubular radiator opening surface with sus-pension, wherein, the tubular radiator is to be formed by the radiating fin assembly group that most arranged askew form, have between each fin at interval, then be protruding with in the bottom surface of radiator contact with heater one connect face, it is characterized in that: the fan group includes a ring frame, one fan seat and rotation flabellum, wherein, interlink with rib between ring frame and the fan seat, flabellum is hubbed on the fan seat, and the bottom surface of flabellum is directed to the inner bottom surface of tubular radiator, and the fan seat then is away from the bottom surface of radiator.

Be directed on the face of radiator at described ring frame, hanging down is provided with the location inserted sheet that corresponds to a group in twos, has a pilot hole again on the ring frames between the two location inserted sheets, and the ring frame is located the inserted sheet branch whereby and inserted in the interval of radiating fin.

Between described two inserted sheets, be horizontally set with a catch, and this catch abuts against the inner edge surface in fin.

Offer air-permeating hole on the surface of described ring frame.

The one line hole of passing power lead is set on the surface of described ring frame.

Owing to adopt such scheme: increase the radiating effect of whole pack heat dissipation device, and make fan keep stable operating condition always, person capable of reducing using again is in the trouble of fit on.

Relevant detailed technology content of the present utility model and embodiment, cooperate now stationary explanation as after.
