Description
The utility model relates to a kind of radiator fan device, particularly relate to a kind of can be effective and rapid radiating and cooling and in good time save the double-fan radiation device of electric energy.
Because the notebook computer volume is little, the inner member setting is comparatively intensive, when its inner generation is hot, also be difficult for shedding voluntarily, therefore at present on general notebook computer, the capital is provided with a radiation fan forced heat radiation in its inside, this radiation fan may be to start shooting promptly to be activated automatically, or controlled by a temperature measurement circuit, just is activated when the inner intensification of notebook computer reaches a predetermined temperature.But; no matter this radiation fan is to start automatically or controlled by temperature measurement circuit; when the notebook computer inside temperature continues to remain high; this radiation fan just must be fought the reforwarding commentaries on classics with heat radiation; right because only by single fan exhaust heat radiation; can't produce good cross-ventilation; hot gas can't be discharged so that still be accumulated in the notebook computer bottom rapidly and successfully; cause notebook computer inside not only can not effectively lower the temperature but also persistently overheating; thereby cause this radiation fan long-time continuous running to dispel the heat; not only cause the lifting of system power consumption, and radiating effect is still bad, and thereby causes system unstable or shut down easily.
Therefore, main purpose of the present utility model provides a kind of double-fan radiation device, makes it reach rapid radiating and cooling and to have effect persons such as in good time saving electric energy by in good time forced air convection.
According to above-mentioned purpose, radiator fan device of the present utility model is arranged in the electronic equipment, it comprises that mainly one can suck cool ambient air the drawing fan in this electronic equipment, one venter that the hot air in the electronic equipment can be discharged, an and temperature control circuit that is electrically connected this drawing fan and venter, and this temperature control circuit can be when this electronic equipment intensification reaches one first temperature, start this venter running, and heat up at this electronic equipment and to reach one when being higher than second temperature of this first temperature, restart this drawing fan running, make to form good cross-ventilation, thus the effect that reaches rapid radiating and cooling and save electric energy in good time.
So double-fan radiation device of the present utility model is arranged in the electronic equipment, it includes devices such as a drawing fan, a venter and a temperature control circuit; Wherein this drawing fan can suck ambient air in this electronic equipment, this venter can be extracted the air in this electronic equipment out, and this temperature control circuit is electrically connected with above-mentioned drawing fan and venter respectively, when this temperature control circuit reaches one first temperature in this electronic equipment intensification, start this venter running, and in this electronic equipment, heat up and reach one when being higher than second temperature of this first temperature, restart this drawing fan running, by forcing to form cross-ventilation, reach the effect of in good time saving electricity and reach rapid radiating and cooling.
The above-mentioned purpose that is to realize for the utility model, technological means and the effect thereof that feature adopts now exemplify preferred embodiment and conjunction with figs. is described as follows:
Shown in Figure 1 is the fan arrangement schematic representation of a preferred embodiment of the present utility model.
Shown in Figure 2 is the circuit block diagram of a preferred embodiment of the present utility model.
DETAILED DESCRIPTION OF THE PREFERRED
At first, Fig. 1 is the configuration schematic diagram of the radiator fan device of a preferred embodiment of the present utility model, and Fig. 2 is the circuit block diagram of the radiator fan device of a preferred embodiment of the present utility model, the radiator fan device 1 of present embodiment is to be arranged in the electronic equipment (being to be a notebook computer 5 in the present embodiment), and it consists predominantly of devices such as a drawing fan 2, a venter 3 and a temperature control circuit 4.
As shown in Figure 1, be the side sectional view of a notebook computer 5, this drawing fan 2 is arranged at 52 1 ventilating holes, 53 places, rear end of notebook computer 5, cool ambient air can be sucked in the notebook computer 5; 3 of this venters are arranged at 51 1 ventilating holes, 54 places, notebook computer 5 bottoms, be in order to notebook computer 5 internal heat air are discharged, and this drawing fan 2 can make the cool air f1 of drawing fan 2 suctions flow to this venter 3 through the formed hot air f2 in heating source (as CPU) 6 backs with the relative position relation of venter 3, by venter 3 hot air is drained into notebook computer 5 outsides.
This temperature control circuit 4 is electrically connected with above-mentioned drawing fan 2 and venter 3 respectively, and it comprises that mainly one surveys the temperature transducer 41 of notebook computer 5 inside temperatures (being above-mentioned heating source 6), and a control chip 42; Wherein this control chip 42 is electrically connected with this temperature transducer 41 and drawing fan 2 and venter 3 respectively, its be available for users to by first temperature and that keyboard to set up one starts this venter 3 start this drawing fan second temperature, and this second temperature is to be higher than this first temperature, then the measured value that temperature transducer 41 can be passed back of this control chip 42 respectively with first temperature that configures and second temperature relatively, when this measured value during greater than first temperature, then start venter 3, and, restart drawing fan 2 when this measured value during greater than second temperature.
So, when notebook computer 5 one is opened use, fan 2,3 is not started at once, when the temperature transducer 41 of temperature control circuit 4 detects notebook computer 5 inside temperatures and is first temperature of setting in greater than control chip 42, promptly start this venter 3 and carry out exhaust, the notebook computer 5 inner hot gas that produce are discharged in good time; And when notebook computer 5 when making for a long time inner persistently overheating second temperature that extremely sets greater than this control chip 42, expression only can't be dispelled the heat rapidly by single venter 3 this moment, then control chip 42 promptly can start this drawing fan 2, and as shown in Figure 1, make drawing fan 2 suck cool ambient air f1, and formed hot air f2 can be discharged into outside the notebook computer by venter 3 after suitably water conservancy diversion makes cool air f1 by heating source 6 process heat exchanges, and form a good cross-ventilation, to pass through the forced air convection mode, increase heat dissipation rate, and reach the effect of rapid reduction notebook computer 5 inside temperatures.
Similarly, when notebook computer 5 inside temperatures comparatively reduce, during second temperature that the measured value that makes this temperature transducer 41 is set less than control chip 42, expression temperature this moment need not use two fans and turn round simultaneously, therefore, control chip 42 fan 2 that can stop suction, and only dispel the heat with venter 3, so can save the power consumption of system in good time, and be closed or its inside temperature is reduced to first temperature that this control chip 42 sets when following in notebook computer 5, just can stop this venter 3 again.
Above-described only is embodiments more of the present utility model, so other equivalent structure of using the utility model specification and claim changes, ought to be included in the claim of the present utility model.
