Fig. 2 shows that part components and parts position concerns synoptic diagram among electronic processing equipment second embodiment of the present invention, and wherein this electronic processing equipment embodiment is a notebook computer, and the low-temperature sensitive device is a battery.As shown in Figure 2, this notebook computer comprises mainboard (not shown), shell (not shown), battery (not shown), battery cover 1, battery cover grid 8, microprocessor (CPU) (not shown), CPU radiating fin (not shown) and cpu fan 5, also comprise the first heat radiation grid 3, the second heat radiation grid 4, the first grid switch (not shown), the second grid switch (not shown), heat insulation gusset 2 and temperature-detecting device (not shown), wherein:
The first heat radiation grid 3 is arranged on (in other words around the CPU, to conduct the heat that CPU work produces well) around the cpu fan 5, all is provided with rotary grid sheet on each grid; Cpu fan 5 is in order to the accelerated heat conduction, by the CPU radiating fin conduction heat that CPU produced, to accelerate the heat radiation of CPU;
The second heat radiation grid 4 is arranged on around the cpu fan 5, all is provided with rotary grid sheet on each grid;
The first grid switch is used to control the rotation of those grid sheets on this first heat radiation grid 3, to open or to cut out this first grid;
The second grid switch is used to control the rotation of those grid sheets on this second heat radiation grid 4, to open or to cut out this second grid; Wherein this first grid switch and the second grid switch are the control device that control heat radiation grid is opened or closed;
Temperature-detecting device, link to each other with the first grid switch and the second grid switch, be used for the temperature that the electronic processing equipment start time detects the battery that this equipment arranges in pairs or groups, when if the temperature of battery is lower than presetting first threshold T1 (such as 10 degrees centigrade), send shutdown signal to the first grid switch and the second grid switch, if this moment, this first heat radiation grid and the second heat radiation grid were in open mode, this first grid switch and the second grid switch are closed this first heat radiation grid and the second heat radiation grid according to this shutdown signal; If being higher than the second default threshold value T2 and this first heat radiation grid and the second heat radiation grid, the temperature of battery is in closed condition, then send start signal to the first grid switch and the second grid switch, this the first grid switch and the second grid switch are opened this first heat radiation grid and the second heat radiation grid according to this start signal, wherein this second threshold value T2 is more than or equal to first threshold T1, and this second threshold value T2 equals this first threshold T1 in the present embodiment.
Above-mentioned isolation gusset 2, role is exactly when notebook computer just starts, the heat that electric capacity on CPU and the mainboard etc. is produced is transmitted to battery surface with heating battery, and separate second heater members, 170 (not shown)s such as electric capacity on the mainboard simultaneously, avoid second heater members 170 rising temperature and influence work efficiency and serviceable life fast under the heat heat effect of generations such as CPU.
Above-mentioned cpu fan 5 when closing, quickens the effect of air flow by it at the first heat radiation grid 3 and the second heat radiation grid 4, when accelerating the CPU heat radiation, has also quickened the intensification of battery.
This notebook computer as shown in Figure 2, its battery is arranged on the mainboard, and battery cover 1 covers on battery surface.When notebook computer was worked under common environment such as room temperature, the heat that battery produces gave out battery cover by battery cover grid 8, avoided the battery operated heat accumulation that produces to quicken cell degradation.
Be under the open mode at this first heat radiation grid 3 and the second heat radiation grid 4, this notebook computer is when work, drive air flow by cpu fan 5, make the air and the fin on the CPU radiating fin that are driven carry out heat interchange, carry the air of heat, the second heat radiation grid 4 by this first heat radiation grid 3 exchanges to notebook computer outside (arrow is represented air-flow direction among the figure), air outside enters in the notebook computer in the mode of compensation, realizes reducing the purpose of cpu temperature.
Be under the closed condition at this first heat radiation grid 3 and the second heat radiation grid 4, the heat that the operation of components and parts such as CPU is produced during this working with notebook computer, air flow that is caused by means of cpu fan 5 and heat insulation gusset to the air guiding function, pass battery cover grid 8 and deliver to battery surface, make the temperature of battery rise as early as possible.
During use, after this notebook computer is started shooting under low temperature environment, the temperature that temperature-detecting device detects battery is lower than first threshold T1, for as early as possible with the temperature increase of battery to suitable battery operated temperature range, temperature-detecting device sends shutdown signal to the first grid switch and the second grid switch.According to this shutdown signal, the first grid switch and the second grid switch are closed this first heat radiation grid 3 and the second heat radiation grid 4.
Because the heats that thermal source produced such as CPU can't distribute by the first heat radiation grid 3 and the second heat radiation grid 4 under the drive of the moving air that cpu fan 5 is caused.Add the existence of heat insulation gusset 2,, impel the temperature of battery to be promoted so have to via battery cover grid 8, be sent to battery according to the water conservancy diversion of heat insulation gusset 2.
Certainly, in actual applications, closing or open the first heat radiation grid 3 and the second heat radiation grid 4, also can be before the notebook computer start, is manually finished according to environment temperature by the user.
Notebook computer is after operation a period of time, because the battery operated heat that produces itself, and the heat that produces by the CPU work of cpu fan 5 and heat insulation gusset 2 conduction, after making that the temperature of battery rises in the normal range of operation (25 spend to 45 degree) rapidly, temperature for fear of battery continues to rise, just should manage to keep or reduce the temperature of battery, battery be had a negative impact to avoid too high temperature.
After the temperature that temperature-detecting device detects battery is higher than the second default threshold value T2, show that the temperature of battery has risen in the normal range of operation, the heat that must again components and parts such as CPU be produced does not conduct to battery, therefore these heats should be distributed.Temperature-detecting device sends start signal to the first grid switch and the second grid switch, and the first grid switch and the second grid switch are opened this first heat radiation grid 3 and the second heat radiation grid 4 according to this start signal.Because this moment first, the heat radiation grid 3 and the second heat radiation grid 4 were in open mode, therefore the heat that produces of components and parts such as CPU, under the moving air effect that cpu fan caused,, be dispersed into the outside of treatment facility via the first heat radiation grid 3 that is in open mode and the second heat radiation grid 4.
Need to prove that this heat insulation gusset 2 not only has guide functions, also has heat-blocking action, with other components and parts except that battery in the protection electronic processing equipment.Because most components and parts in the electronic processing equipment, all very sensitive to temperature, too high temperature can exert an influence to the serviceability and the life-span of those components and parts, therefore when the heat with generations such as CPU conducts to battery, be necessary to guarantee that this heat does not influence the temperature of other components and parts in the equipment as far as possible.Under the heat-blocking action of heat insulation gusset 2, the heat that well heater produced can not conduct on the mainboard on other the components and parts, can not exist those components and parts Yin Wendu too high and break down even produce the hidden danger of safety problem.
Need to prove, when if equipment has just been started shooting, the temperature that temperature-detecting device detects battery is higher than this second threshold value T2, and promptly current being in is fit to battery operated temperature range, then can not send start signal to the first grid switch and the second grid switch.Generally speaking, the temperature that only detects battery is lower than this first threshold T1, and earlier after the first grid switch and second grid switch transmission shutdown signal, the temperature that detects battery is elevated to this second threshold value T2 when above, just can send start signal, to open this first heat radiation grid and the second heat radiation grid dispels the heat to the first grid switch and the second grid switch.
Need to prove, be with two heat radiation grids structure that is example explanation notebook computer in the present embodiment, and the on-off action of these two heat radiation grids is consistent.In fact, the switching of these two heat radiation grids also can be asynchronous, promptly only controls one of them heat radiation grid and open or close, and also allows.In addition, in some other embodiment, also can be one, three or more grids that dispel the heat, the present invention is to the not restriction of quantity of heat radiation grid.
Need to prove, iff being by heat insulation gusset 2 is set, the heat of generations such as CPU is directed to the surface of battery etc., and does not close the grid sheet of heat radiation grid, also can improve the temperature of battery etc.
Fig. 3 shows that part components and parts position concerns synoptic diagram among electronic processing equipment the 3rd embodiment of the present invention, and the 3rd embodiment is similarly a notebook computer.Compare with second embodiment shown in Figure 2, the 3rd embodiment more comprises an electric heater and a heater button.In conjunction with second embodiment shown in Figure 2, among the 3rd embodiment shown in Figure 3:
Temperature-detecting device, link to each other with the first grid switch, the second grid switch and heater button (not shown), when the temperature that detects battery is lower than one the 3rd threshold value T3 (as 0 degree), send shutdown signal closing the first heat radiation grid 3 and the second heat radiation grid 4 to this first grid switch and the second grid switch, and send a working signal to this heater button; When the temperature that detects battery is lower than this first threshold T1 but is higher than the 3rd threshold value T3, send shutdown signal to close the first heat radiation grid 3 and the second heat radiation grid 4 to this first grid switch and the second grid switch; Wherein this first threshold T1 is more than or equal to the 3rd threshold value T3, and in the present embodiment, this first threshold T1 is 10 degrees centigrade, and the 3rd threshold value T3 is 0 degree centigrade; When the temperature that detects battery has been higher than one the 4th threshold value T4, send a stop signal to well heater 7 switches, control electric heater 7 quits work; Wherein the 4th threshold value T4 is more than or equal to the 3rd threshold value T3, and the 4th threshold value T4 equals the 3rd threshold value T3 in the present embodiment; Temperature at battery continues to promote, and reaches when being higher than this second threshold value T2, sends start signal to the first grid switch 3 and the second grid switch 4;
Heater button links to each other with temperature-detecting device and electric heater 7, heats according to the working signal opening electric heater 7 that temperature-detecting device sent, and according to the stop signal that temperature-detecting device sent, control electric heater 7 quits work;
Select to adopt external power source to provide electric energy for electric heater 7, then when working, electronic processing equipment just can not carry out preheating for battery, also be before electronic processing equipment is started shooting, can adopt external power source to provide electric energy for electric heater 7, make electric heater 7 provide heat for the components and parts of electronic processing equipment inside and the battery of being arranged in pairs or groups etc., make electronic processing equipment and cell integrated raising temperature, and then start operation electronic processing equipment.
Because electric heater 7 and heat that CPU produced, and the heat effect that produced of battery work itself, the temperature of battery is continued lifting.When the temperature that detects battery at temperature-detecting device has been higher than the 4th threshold value T4, can send a stop signal to heater button, control electric heater 7 quits work, with the electric weight in the conserve batteries.Certainly, also can be send stop signal, allow electric heater 7 work on, make the temperature of battery rise to the temperature range of suitable work as early as possible so that heat to be provided to the electric heater switch.Continue to rise to when being higher than this second threshold value T2 in the temperature of battery, the temperature that battery is described has been within the suitable battery operated normal range, this moment, temperature-detecting device need send start signal to the first grid switch 3 and the second grid switch 4, to open the first heat radiation grid 3 and the second heat radiation grid 4 dispels the heat.
When adopting external power source to heat for low-temperature sensitive devices such as batteries by well heater 7, temperature-detecting device carries out work by external power source simultaneously, detects the temperature of low-temperature sensitive devices such as battery.After detecting this temperature and rising to the 4th threshold value T4, send a stop signal to this well heater 7, control electric heater 7 quits work, and report to the police to the external world by an audible alarm unit (not shown), risen to the temperature range of suitable work to the temperature of user prompt low-temperature sensitive device.
Need to prove that when if equipment has just been started shooting, the temperature that temperature-detecting device detects battery is lower than this first threshold T1 but is higher than the 3rd threshold value T3, then can not send stop signal to heater button.When if equipment has just been started shooting, the temperature that temperature-detecting device detects battery is higher than this first threshold T1, then can not send start signal to the first grid switch and the second grid switch.
Under utmost point low temperature (as subzero below 20 degrees centigrade) environment, the heat that only relies on CPU work to be produced may also can't improve the temperature of battery rapidly.At this moment, the heat that these electric heater 7 work are produced, in company with the energy that CPU work is produced, the guide functions by cpu fan 5 and heat insulation gusset 2 all is passed to battery, makes the temperature of battery to rise as early as possible.
More than during each implements, it is of the present invention all to be that CPU with notebook computer is that thermal source illustrates.In fact, in notebook computer, the heat that produces during work is fit to be directed to low-temperature sensitive devices such as battery and to its device that heats, also comprises north bridge.Fig. 4 shows electronic processing equipment the 4th embodiment of the present invention, the 4th embodiment compares with the 3rd embodiment shown in Figure 3, the heat that produces when heat insulation gusset 2 not only is used for CPU worked is directed to battery, is used for also that the heat of generation was directed on the battery with heating battery when north bridge (figure illustrates with the heat radiator 9 of north bridge) work.
More than each embodiment be the notebook computer battery of being arranged in pairs or groups with the protection integrated graphics card is an example, some embodiments of the present invention are described.Fig. 5 shows electronic processing equipment the 5th embodiment of the battery that notebook computer is arranged in pairs or groups of the independent video card of protection.As shown in Figure 5, the thermal source among the 5th embodiment not only comprises CPU and north bridge (heat radiator 9 with north bridge among the figure illustrates), also comprises independent video card (heat radiator 10 with independent video card among the figure illustrates).The heat that heat insulation gusset 2 produces when not only being used for the work of CPU and north bridge is directed to battery, also is used for heat that this independent video card is produced, is directed on the battery with heating battery.
When electronic processing equipments such as notebook computer are worked under low temperature environment, except battery is produced the harmful effect, also can be to driver, such as hard disk drive (Hard Disk Drive, HDD) and CD drive (Optical Disk Drive ODD) produces harmful effect.When driver was worked under low temperature environment, when the startup of motor wherein, read-write head swing arm and mechanical devices and running, noise was very big, and can shorten the life-span of using driver.
In some other embodiment of the present invention, the heat that thermal source and electric heater produced is by the guiding of heat insulation gusset, in order to the temperature of heat driven device.Under utmost point low temperature environment, can heat electric heater by external power supply, the heat that electric heater produced is used for the preheating electronic processing equipment, and when the temperature of driver rises to suitable drive operation, and then the unlocking electronic treatment facility carries out work.
Temperature-detecting device among the present invention is after the temperature that detects the low-temperature sensitive device has been in the temperature range of suitable this device work, by control heat radiation grid, the heat of CPU etc. is derived, can not have a negative impact to this device, more can not produce generation because continuing heating such as hazard events such as battery explosions because of continuing heating.
Electric heater in the foregoing description can be powered by the battery of electronic processing equipment, but it is the low-power well heater, can be because of the use of this electric heater the obvious electric energy in the consuming cells.Generally, this well heater carries out preheating to the low-temperature sensitive device when electronic processing equipment is just opened, after electronic processing equipment work a period of time, the temperature of low-temperature sensitive device generally all can rise to rapidly and be suitable for the temperature that electronic processing equipment carries out work, so also can not produce potential safety hazard.Certainly, when electronic processing equipment is not started working, just adopt the external power supply power supply, also can improve the temperature of low-temperature sensitive device by the work of electric heater.In the embodiment of these protection drivers, temperature-detecting device is used to detect the temperature of driver, and sends signal according to testing result to heat radiation grid etc.
