Preferably, in this heater members audio frequency power amplifier, CPU, the charge controller any one.

Positive progressive effect of the present utility model is: heat abstractor of the present utility model has utilized the thermo-electric generation technology, both solved the heat dissipation problem of handheld mobile device itself, the electric energy that heat energy transforms second use be can be carried out again, the service time of device battery and the useful life of equipment prolonged.

Description of drawings

Fig. 1 is the construction for heat radiating device schematic diagram of the utility model preferred embodiment.

Fig. 2 is the heat abstractor circuit diagram of the utility model preferred embodiment.

Embodiment

Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

Handheld mobile device commonly used, such as mobile phone, in use, because the heater members in it, such as: radio-frequency (RF) power amplification or power-supply controller of electric also can be charge controllers etc., can produce very high heat usually, as 65 degree~85 degree.If the mobile phone temperature rise is very high, will have a strong impact on the life-span of normally using and using of mobile phone, and also very big to battery consumption.In order to solve this technical barrier, heat abstractor of the present utility model is that known thermo-electric generation technology in the technical field of refrigeration equipment is applied in the handheld mobile device heat dissipation technology in a creative way, solve the heating problem during handheld mobile device uses effectively, and prolonged the service time of battery.

In the refrigeration plant technology, usually can adopt the thermo-electric generation principle of a kind of Xi Baike of crying (seebeck) effect in the thermo-electric generation technology to carry out absorbing and cooling temperature.It is meant in the open circuit of being made up of two kinds of different conductors, if there is temperature difference in two nodes of conductor, will produce electromotive force in this open circuit, and heat energy is converted into electric energy.The temperature difference at generating body two ends is big more, and energy output is just big more.This technology is usually used in main equipment coolings such as oil field and field, does not find to apply to the heat dissipation technology field of handheld mobile device at present as yet.

As Fig. 1, shown in Figure 2, a kind of heat abstractor that is used for handheld mobile device of the present utility model, it comprises a thermo-electric generation assembly 1 at least, one Voltage stabilizing module 2, one charging module 3, wherein, this thermo-electric generation assembly 1 is located at the top of this heater members 8, this thermo-electric generation assembly 1, Voltage stabilizing module 2 and charging module 3 are connected in series back and this built-in power successively, such as battery 4, form a control loop 6, because of the heater members 8 that has is nonisulated device, then in order to prevent that thermo-electric generation assembly 1 and heater members 8 are short-circuited, being provided with the less insulating trip 7 of a thermal resistance between electrification component 1 and heater members 8, such as mica sheet, is circuit board of mobile phone 9 below the insulating trip 7.The volume of considering handheld device such as mobile phone is generally all very little, and the thermo-electric generation assembly 1 of present embodiment is selected the semiconductor temperature differential generating body of the parallel with one another or series connection of semiconductor thermo-electric generation body or a group for use.The semiconductor temperature differential generating body is by two kinds of different qualities, as: the formation that combines of P type semiconductor and N type semiconductor.As long as temperature difference is arranged, will produce electrical potential difference, produce electric energy.

As shown in Figure 2, because producing heat, heater members 2 causes that the temperature difference is arranged, the semiconductor temperature differential generating body produces electric energy power supply source 3 or other power supply circuits 5 use, because heater members 8 caloric value differences, then the energy output difference of semiconductor temperature differential generating body causes the supply power voltage shakiness, so will be equipped with voltage stabilizing circuit 2, make the voltage of temperature difference output of semiconductor temperature differential generating body more stable, be equipped with charging circuit 3 simultaneously and give battery 4 chargings.Like this can the unnecessary heat energy of recovery section, offer battery 4, reach and prolong the battery purpose of 4 service times.Voltage stabilizing circuit 2 in the utility model and charging circuit 3 parts are the known technology of this area, so do not repeat them here.

Heat abstractor of the present utility model has utilized the principle of thermo-electric generation technology just, by the semiconductor thermo-electric generation body of in mobile phone, packing into, utilize the character of semiconductor PN, when there are enough temperature difference in the semiconductor PN two ends, the semiconductor PN both sides will produce voltage, if at this moment semiconductor temperature differential generating body and battery of mobile phone 4 are connected to form control loop 6, can form electric current, then with heat absorption unnecessary in the mobile phone body, thereby realize the heat radiation purpose of handheld mobile devices such as mobile phone.

In addition, the electric energy that utilize to transform can also be given battery 4 chargings or use for other power supply circuits 5, thereby prolongs 4 service times of battery, make not only energy-conservation but also environmental protection of handheld device, and serviceability is stable.

Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these execution modes.Therefore, protection range of the present utility model is limited by appended claims.
