Description
Technical field
The present invention relates to the computer chip heat abstractor, particularly a kind of dynamic computer chip radiator, the substrate that this dynamic computer chip radiator contacts with heating surface is in the motion shape, can strengthen its thermotransport ability.
Background technology
Current, along with the growth at full speed of computer chip integrated level, the solution of superhigh intensity heat dissipation problem is more and more got into a difficult position.The present state of the art is, computing machine generally adopts the forced convection air to cool off heater members, promptly by the expansion fin, the improvement air-flow distributes, increase blast, the cooling air force feed was loose should locate heat to spreader surface, and the cooling effectiveness of this kind mode is directly proportional with fan speed, thereby can produce obvious noise; In case and the micro element heat generation density is when too high, traditional air cooling will be difficult to be competent at.Therefore, must be improved this.
For in the performance that promotes the fin heat dissipation technology to a greater extent, the present invention provides a kind of notion of dynamic computer chip radiator first.The principle of work of this dynamic computer chip radiator is like this: heat spreader structures is consistent with traditional finned radiator, air-flow cooling radiator fin by fans drive, but the substrate that dynamic computer chip radiator comprises not is to be fixed in the euthermic chip surface as traditional approach, and the motion state that is in contact all the time on the euthermic chip surface or breaks away from, like this, substrate by this heating radiator contacts and disengaging with the dynamic of euthermic chip hot junction, the heat of chip surface can be transferred to far-end rapidly; Relend the relative motion that helps fan airstream and substrate, the heat that can continuously chip heating end be produced better transmission is rapidly walked; Afterwards, cooled heating radiator substrate is returned to and the contacted state of heating surface once again, accepts heating, so moves in circles, and the heat delivered that is about to chip heating end is to far-end.
The present invention is because the heating radiator substrate is in the motion state as the fluid, thereby provide simultaneously and flowed and two kinds of heat transfer modes of heat conduction, and because the heating radiator substrate is high-thermal conductive metal, thereby its transfer rate surmounts in any fluid type of cooling in the past; And it is not high to drive the required power consumption of heating radiator motion, and control is convenient, compact conformation, and this is the not available advantage of conventional fluid type of drive, it also becomes extremely valuable place of the present invention.
Summary of the invention
The object of the present invention is to provide a kind of dynamic computer chip radiator, be used for cooling to euthermic chip, this is a kind of active heat removal device of low-power consumption, adopt high thermal conductivity the metal conduct the heating radiator substrate and utilize the motion of heating radiator substrate to reach the purpose of heat transportation.
Technical scheme of the present invention is as follows:
Dynamic computer chip radiator provided by the invention comprises:
One with computer chip heater element 1 surperficial contacted heating radiator substrate 3 to be cooled; Have radiated rib 4 on the surface, other end of described heating radiator substrate 3; With

During use, the heat that spreads out of from chip heater element to be cooled 1 surface is absorbed by heating radiator substrate 3, heating radiator substrate 3 temperature behind the absorption heat raise rapidly and leave chip heater element to be cooled 1 surface, cool off by heat conduction and convection type afterwards, finish cooled heating radiator substrate 3 again with euthermic chip surface contact heat-exchanging.
Because the temperature conductivity height of heating radiator substrate 3, thereby the end heating that is easy to be generated heat, thereby its substrate breaks away from when generating heat end surfaces and being exposed to surrounding environment, because surface temperature is higher, its radiating effect is very remarkable, this just is equivalent to the heater element surface is expanded greatly, thereby helps the discharging of heat.
Whole process heater element 1 surface can contact (as Fig. 1 with heating radiator substrate 3 continuously, shown in Figure 2) or batch (-type) contact (as shown in Figure 3), be easy to by environment cools with the heating radiator substrate 3 after heater element 1 surface contacts, this has just overcome in traditional heating radiator need pass to the fin surface by the bottom surface by means of heat conduction, thereby outside surface and circumstance of temperature difference are less, so that be unfavorable for the drawback of dispelling the heat.In Fig. 1, heating radiator substrate 3 contacts with the euthermic chip surface continuously, and the noncontact part is cooled off with fan or other modes, between heater element 1 and heating radiator substrate 3, is added with the heat-conducting medium layer so that reduce thermal contact resistance and friction.In Fig. 2, slip heating radiator substrate 3 contacts with chip surface to be cooled, the noncontact part is cooled off with fan or other modes, between euthermic chip and heating radiator substrate 3, also there is heat-conducting medium to be used to reduce thermal contact resistance and reduces and rub, in Fig. 3, heating radiator substrate 3 is with after chip surface to be cooled contacts certain hour, by breaking away from the euthermic chip surface after the effect of driving mechanism 9, adopt modes such as convection current or jet impulse that euthermic chip surface and heating radiator substrate 3 are cooled off during the disengaging, heating radiator substrate 3 contacts with the euthermic chip surface again behind the certain hour.Heating radiator substrate 3 is driven by micro driving mechanism, can rotate, and slides or breaks away from and move.The dynamic computer chip radiator that the present invention proposes, fin can be by highly heat-conductive material or the manufacturings of its compound substance such as copper, aluminium, silver, graphite, carbon, and its fin shape or distribution mode can variations.At dynamic computer chip radiator, can implement to be forced to the air cooling to the heating radiator substrate by one or several fans, position of fan can be installed in heating radiator substrate 3 tops as required, perhaps the below, be installed in the below fan be for cooling radiator substrate faster 3.
Crucial part of the present invention is to have introduced campaign-styled heating radiator, thereby the heating radiator substrate 3 that temporarily breaks away from the euthermic chip surface can contact with the euthermic chip surface after the cooling that stands environment once again, thereby increased the temperature difference of euthermic chip surface with heating radiator substrate 3, and utilized two kinds of heat transfer types of similar convection current and heat conduction, thereby strengthened heat exchange.The present invention changes the traditional die heating radiator and euthermic chip is fixed thereby the mode of the difficult cooling in bottom, can make total heat radiation density higher.
