As shown in Figure 3, one embodiment of the present of invention provide a kind of mobile terminal, comprising:
Battery 310, has temperature sensor on battery 310, for detection of the temperature of battery. In this enforcementIn example, the type of temperature sensor is not limited, any device that can gather battery temperature all canUsing as temperature sensor, for example it can be thermistor; In the present embodiment, for the class of batteryType does not limit, and it can be lithium ion battery, can be also other types battery.
Processor 320, processor 320 obtains the temperature of battery 310 from temperature sensor, and at battery310 temperature during lower than the first temperature value, improves the operating frequency of processor 320, to increase processor320 heats that produce. In the present embodiment, processor 320 is CPU, and its operating frequency changes,When the operating frequency of CPU improves, its heating also increases thereupon; In the present embodiment, to the first temperatureDegree value does not limit, and for example, the suitable operating temperature of lithium ion battery is 0 DEG C-40 DEG C, and firstTemperature value can be got 0 DEG C.
The first Heat Conduction Material, the thermal conductivity factor of the first Heat Conduction Material exceedes the first thermal conductivity factor, the first heat conductionThe heat that material produces processor 320 passes to battery 310. In the present embodiment, the first thermal conductivity factorCan arrange higher, to ensure the good heat conductive performance of the first Heat Conduction Material, for example, the first Heat Conduction MaterialCan be the metal material that thermal conductivity factor is large, as copper alloy, aluminium alloy etc.
In the present embodiment, one of ordinary skill in the art will readily recognize that the heat that processor 320 produces increasesTime battery 310 temperature improve. Even if the residing environment temperature of mobile terminal is-10 DEG C, but owing to locatingReason device 320 has improved operating frequency, and the amount of heat of generation is delivered to battery 310 through the first Heat Conduction Material,Can make the temperature of battery 310 remain on more than 0 DEG C, thereby battery 310 can enter under proper temperatureRow work, ensures that the performance of battery 310 is without prejudice.
An alternative embodiment of the invention provides a kind of mobile terminal, than previous embodiment, this realityExecute routine mobile terminal, processor 320 is in the temperature of battery 310 during higher than the second temperature value, reduction placeThe operating frequency of reason device 320, the heat producing to reduce processor 320. In the present embodiment, secondTemperature value does not limit, and for example, the suitable operating temperature of lithium ion battery is 0 DEG C-40 DEG C, andTwo temperature values can be got 5 DEG C.
In the present embodiment, one of ordinary skill in the art will readily recognize that the heat that processor 320 produces reducesTime battery 310 temperature reduce. In the present embodiment, in the time that battery 310 is worked under proper temperature,There is no need to continue to increase the temperature of battery 310, to avoid the excess Temperature of battery 310, and keep awayExempt from processor 320 while carrying out high-frequency work, bring unnecessary power consumption.
An alternative embodiment of the invention provides a kind of mobile terminal, than previous embodiment, this realityExecute routine mobile terminal, also comprise:
Heater members 330, the heat that heater members 330 produces is passed to battery 310 through the first Heat Conduction Material.In the present embodiment, due in mobile terminal except processor 320, often also exist otherThe device (as some chips) that can generate heat, the heat that therefore these heater members 330 can be produced alsoConduction, to battery 310, with the heat waste of avoiding heater members 330 to produce, makes the temperature of battery 310Fast lifting.
An alternative embodiment of the invention provides a kind of mobile terminal, than previous embodiment, this realityExecute routine mobile terminal, also comprise:
Center, center is divided into the middle arch 340, center middle part 350 and the middle frame bottom that are hierarchy360, wherein center middle part 350 is hollow, and middle frame bottom 360 has the first Heat Conduction Material.
