Embodiment
For making the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
Cooling system described in the specific embodiment of the invention, comprising:
Checkout gear, for the heat dissipation ventilation mouth of detected electrons equipment, judges whether described heat dissipation ventilation mouth blocks by outside;
Responding device, during for judging that described heat dissipation ventilation mouth blocks by outside when described checkout gear, giving the alarm to user and/or adjusting the radiation parameter of described electronic equipment.
By described cooling system, can the heat dissipation ventilation mouth of detected electrons equipment, when judging that heat dissipation ventilation mouth blocks by outside, give the alarm reminding user, or respond, the radiation parameter of adjustment electronic equipment, system temperature is reduced, thus avoid ignoring heat dissipation ventilation mouth as user, cause the very fast rising of temperature in system when being plugged, abnormal, the even overheated situation about burning out of system running.
Below the implementation of cooling system described in the specific embodiment of the invention is described in detail.
Cooling system described in first embodiment of the invention, by detecting the situation of the placed side of the supporter being used for support electronic equipment, judging whether the heat dissipation ventilation mouth of electronic equipment exists and occurring by outside situation of blocking.
Wherein, when electronic equipment is notebook computer, this heat dissipation ventilation mouth can be the air inlet of notebook computer, it will be understood by those skilled in the art that the air inlet of notebook computer is arranged at bottom surface usually.Also, namely when heat dissipation ventilation mouth is air inlet, when being arranged at the first surface of the housing of notebook computer, this first surface is notebook computer when being positioned on the supporting surface of supporter, the surface nearest with described supporting surface.
On the base of usual notebook computer, there are some supported design in capital, if notebook computer is placed on the planar medium of hard material, these supported design effectively can support notebook computer, make between notebook computer and supporter, to keep certain airspace, the bottom of notebook computer would not be close on a support, by groove or opening (exhaust outlet/air inlet) the realization heat radiation of bottom; Preferably, laptop bottom, for arranging air inlet, makes cool exterior air flow into internal system.But, if notebook computer is placed on out-of-flatness software on the surface, such as: be placed on sofa, bed, when thing Deng softness is surperficial, the thing of these softnesses can be easy to the heat dissipation ventilation mouth of laptop bottom to block, and the heat radiation of notebook computer is gone wrong, and system temperature rises, if there is no Timeliness coverage, then the overheated situation about burning out of notebook computer may be caused to occur.
Therefore, in cooling system described in first embodiment of the invention, contacted with supporting surface by checkout gear, detect the support elasticity of described supporting surface, when the support elasticity detected is greater than predetermined value, then judge that the heat dissipation ventilation mouth of electronic equipment blocks by outside.
Like this, adopt the heat dissipating method of described cooling system, can judge exactly when electronic equipment is positioned over soft-surface, heat dissipation ventilation mouth is by outside situation of blocking, no longer simple passive tracking monitoring system temperature thus, but the residing hazardous environment of electronic equipment effectively can be detected, pass through Scenario Prediction, before problem not yet occurs (temperature does not also raise), namely adopt an effective measure and avoid danger, thus effectively avoid electronic equipment to cause overheated burning out or the generation of loss situation because heat dissipation ventilation mouth is blocked.
Cooling system described in first embodiment of the invention, described checkout gear comprises at least one pressure sensor, when the pressure that pressure sensor detects is less than the first force value, determine that the support elasticity of supporting surface to electronic equipment is greater than predetermined value, heat dissipation ventilation mouth can block by outside, and also namely supporting surface shows the force value that the support elasticity of electronic equipment is detected by pressure sensor.The pressure that responding device detects according to pressure sensor, judge whether heat dissipation ventilation mouth blocks by outside, when the pressure determining that pressure sensor detects is less than the first force value, then judge that heat dissipation ventilation mouth blocks by outside, give the alarm to user and/or adjust the radiation parameter of electronic equipment.
Fig. 1 is for adopting the bottom surface structural representation of the electronic equipment of cooling system described in first embodiment of the invention.
Electronic equipment be positioned over supporter (as on desktop time), bottom surface 110 (first surface) is the surface nearest apart from the supporting surface of supporter, usual bottom surface 110 is provided with contact pad 111, for directly contacting with the supporting surface of supporter, make to keep a clearance distance between bottom surface 110 and the supporting surface of supporter, form certain airspace, make electronic equipment realize heat radiation by the heat dissipation ventilation mouth 120 on bottom surface 110.
Each contact pad 111 is provided with a pressure sensor 130, therefore pressure sensor 130 has the number N corresponding with contact pad 111, as shown in Figure 1, in the present embodiment, the contact pad 111 of described electronic equipment has four, distribution is arranged at the corner location of bottom surface 110, then electronic equipment is provided with four pressure sensors 130.Be understandable that, the quantity of contact pad 111 is not limited to four, and therefore the magnitude setting of pressure sensor 130 is also not limited to four, as being two, three or five etc., can set according to actual conditions.
According to above setting, when electronic equipment is placed naturally, under electronic equipment Action of Gravity Field, the weight of electronic equipment can be measured by pressure sensor.When electronic equipment is positioned in hard dielectric surface situation, each contact pad 111 bears 1/4 deadweight, then each force value measured by pressure sensor 130 then equals 1/4th of electronic equipment weight, and the force value summation that each pressure sensor 130 is measured equals the total weight of electronic equipment.
When to be placed on supporting surface be under soft dielectric surface to electronic equipment, the pressure sensitive of each contact pad 111 will change, the first situation as shown in Figure 2, when supporting surface 210 elasticity placed is larger, supporting surface 210 is out of shape obviously, then the bottom surface 110 of electronic equipment is got deeply stuck in in the Supporting Media of supporting surface 210, the now deadweight of electronic equipment is disperseed, no longer all bear weight by contact pad 111, the bottom surface 110 of electronic equipment has also shared moiety by weight, the summation of the force value then measured by four pressure sensors is less than the total weight of electronic equipment, also be N1+N2+N3+N4 < G, wherein N1, N2, N3 and N4 is respectively the force value measured by four pressure sensors, G is the total weight of electronic equipment.
In above-mentioned situation, N1, N2, N3 and N4 are all non-vanishing, also namely four contact pads 111 of electronic equipment are all stressed, not unsettled, due to except four contact pads 111 contact with supporting surface 210, other positions of the bottom surface 110 of electronic equipment also contact with supporting surface 210, have shared weight, therefore make the summation of the force value measured by four pressure sensors be less than the total weight of electronic equipment.
Fig. 3 is the another kind of situation that electronic equipment is positioned over that supporting surface is soft dielectric surface.Consult shown in Fig. 3, electronic equipment is placed on to be had on certain flexible supporting surface 310, but compared to situation shown in Fig. 2, the elasticity in this kind of situation lower support face 310 is less than the elasticity in Fig. 2 situation lower support face 210.
Under situation shown in Fig. 3, supporting surface 310 slight deformation, the bottom surface of electronic equipment is not trapped in the soft dielectric surface of supporting surface 310 completely,, namely except the contact pad 111 of electronic equipment contacts with supporting surface 310, there is not the part contacted with supporting surface 310 in the bottom surface of electronic equipment yet.The weight of electronic equipment is still shared by four contact pads 111, but compare (as shown in Figure 4) with to be positioned on hard interface stressed, in situation shown in Fig. 3, because soft depression causes the lifting surface area of contact pad 111 to increase, pressure sensor 130 is arranged at the centre of contact pad 111, pressure is shared from the side due to slight deformation, therefore makes each force value detected by pressure sensor 130 diminish.
Like this, the summation of the force value that also can exist measured by four pressure sensors 130 is less than the situation of the total weight of electronic equipment, is also N1+N2+N3+N4 < G.
Situation according to above-mentioned Fig. 2 and Fig. 3, can find out, when electronic equipment be positioned over have on certain flexible supporting surface time, the summation of the force value measured by four pressure sensors 130 can be less than the total weight of electronic equipment, therefore can be normative reference according to the force value summation measured by four pressure sensors 130, determine whether supporting surface can block the predetermined value of heat dissipation ventilation mouth by being used for, corresponding with the gross weight value of electronic equipment, once the force value summation measured by pressure sensor 130 is less than the gross weight value of electronic equipment, then determine that the support elasticity of supporting surface is greater than predetermined value, judge that heat dissipation ventilation mouth can block by outside.
In addition, by analysis chart 2 and Fig. 3, can find out, under situation shown in Fig. 3, although the force value summation measured by four pressure sensors is less than the gross weight value of electronic equipment, between the bottom surface of electronic equipment and supporting surface, still leave certain interval, but be also unlikely to block heat dissipation ventilation mouth, only have when situation shown in Fig. 2, when the bottom surface of electronic equipment also contacts with supporting surface, just can block the situation of heat dissipation ventilation mouth.Therefore, for accurately detecting supporting surface blocking heat dissipation ventilation mouth, can be determined by experiment that the contact pad of situation shown in Fig. 3 111 is whole is absorbed in supporting surface, but when the bottom surface of electronic equipment does not contact with supporting surface, force value summation N5 measured by four pressure sensors 130, also namely measure supporting surface heat dissipation ventilation mouth is blocked before critical condition, determine whether supporting surface can block the predetermined value of heat dissipation ventilation mouth by being used for, corresponding with this critical pressure value N5, once the force value summation measured by pressure sensor 130 is less than this critical pressure value N5, then determine that the support elasticity of supporting surface is greater than predetermined value, judge that heat dissipation ventilation mouth can block by outside.
Certainly, those skilled in the art also can according to the heat radiation actual demand of electronic equipment, other critical parameters of setting pressure transducer, for judging whether supporting surface can cause heat radiation air port to be blocked.
In addition, by pressure sensor, cooling system described in first embodiment of the invention, can determine that whether heat dissipation ventilation mouth is by except outside situation of blocking, and can also measure the situation of the incorrect placement of electronic equipment except above-mentioned.Such as, when the force value detected by the wherein at least one pressure sensor in four pressure sensors is 0, then can determine that wherein a contact pad does not contact with the support of supporter, electronic equipment exists unsettled, be not normally positioned, in that case, responding device also can according to the detection of pressure sensor, give the alarm to user, to point out user.
Cooling system described in first embodiment of the invention, when according to above-mentioned detection mode, when checkout gear judges that heat dissipation ventilation mouth blocks by outside, for preventing causing the overheated situation about burning out of electronic equipment to occur, the testing result of responding device to checkout gear of electronic equipment responds, and specifically can carry out according to following steps:
Step S501, obtains the testing result of pressure sensor;
Step S502, checkout gear judges whether heat dissipation ventilation mouth blocks by outside, when judged result is no, then performs step S503 downwards, when judged result is for being, then performs step S504 downwards;
Step S503, electronic equipment dispels the heat according to the first radiating control state;
Step S504, alarm user, and perform step S505 downwards;
Step S505, judges whether user adjusts the placement of electronic equipment, when judged result is for being, then performs step S506 downwards, when judged result is no, then performs step S507 downwards;
Step S506, stop alarm, recover normal, electronic equipment still dispels the heat according to the first radiating control state;
Step S507, judge that system temperature is greater than the second predetermined temperature T2, is less than the first predetermined temperature T1 still between T2 and T1, wherein T2 is greater than T1; When system temperature is less than the first predetermined temperature T1, then perform step S506; When system temperature is between the first predetermined temperature T1 and the second predetermined temperature T2, then perform step S508; When system temperature is greater than the second predetermined temperature T2, then perform step S509;
Step S508, electronic equipment dispels the heat according to the second radiating control state; Wherein, system current temperature value be in be greater than the first predetermined temperature T1 and be less than the second predetermined temperature T2 time, if under the first radiating control state described, current temperature value declines with first rate, if under described the second radiating control state, current temperature value declines with the second speed, and wherein said first rate is less than described second speed;
Step S509, electronic equipment dispels the heat according to the third radiating control state; Wherein, when system current temperature value is in the temperature being greater than the second predetermined temperature T2, if under described the second radiating control state, described current temperature value declines with the second speed, if under the third radiating control state described, described current temperature value declines with third speed, and wherein said second speed is less than described third speed.
Above-mentioned radiating mode, when being judged that by checkout gear heat dissipation ventilation mouth blocks by outside, and when in system, temperature exceedes set point, for preventing causing overheated situation about burning out, adopt step S508 and step S509, change system radiating control mode, make intrasystem Current Temperatures compared with normal radiating control mode with more rapid rate decline.
Such as, with following table 1 for representing the radiating control parameter under the first radiating control state, table 2 is for representing the radiating control parameter under the second radiating control state.
Table 1
Table 2
Can be preset by electronic equipment for providing the first heat radiation table of the above-mentioned form of radiating mode and the second heat radiation table and preserve, when not detecting that heat dissipation ventilation mouth is blocked, system adopts the first radiating control state (also i.e. table 1) to dispel the heat, and adopts corresponding radiating control parameter to dispel the heat according to intrasystem current temperature value.When detecting that heat dissipation ventilation mouth is blocked, and when system temperature is between T1 and T2, system adopts the second radiating control state (also i.e. table 2) to dispel the heat.
If the first predetermined temperature T1 is 85 degree, contrasted by table 1 and table 2, can find out, when temperature in system is greater than 85 degree, the second radiating control state of employing table 2 is dispelled the heat, and the first the radiating control state compared to employing table 1 is dispelled the heat, under identical current temperature value, rotation speed of the fan improves or frequency reducing percentage increases, thus makes the temperature fall off rate under the second radiating control parameter faster.
In like manner, when temperature is greater than the second predetermined temperature value T2 in system, adopt the third radiating control state to dispel the heat, dispel the heat compared to employing the second radiating control state, in system, temperature fall off rate is faster.No longer describe in detail at this.In addition, when detecting that in system, temperature is too much higher than the second predetermined temperature value T2, the third radiating control state also can adopt the operator scheme making electronic equipment enter not eye or shutdown, and temperature in system is declined fast.
