The charging device of mobile device of the present invention is a heat of utilizing mobile device to produce, produces hot gas electric power, utilizes the hot gas electric power that produces, and carries out oneself's charging.Specifically, the charging device of mobile device of the present invention comprises following structure: the thermal conversion that will be included in the heat radiation accessory generation of mobile device inside is the hot gas electricity generating section of electric energy; Receive the electric power of above-mentioned hot gas electricity generating section output, to the charging part of TunePower supply charging current; The voltage that the charging current that utilization receives from above-mentioned charging part is imported, the battery of driving mobile device.
Personal digital assistant), notebook computer, portable game machine, portable laser phonograph, digital camera, MP3 player, PMP (portable multimedia player: portable media player), user such as satellite dmb receiving terminal machine, the surface wave DMB receiving terminal machine portable information device that carries, use " mobile device " among the present invention refers to PDA (Personal Digital Assistant:.These mobile devices are using the charging device among the present invention now, and in the future, the charging device among the present invention may be suitable in all mobile devices.
Fig. 2 is the functional-block diagram of the mobile charging device of one embodiment of the invention.As shown in Figure 2, the charging device of the mobile device of the embodiment of the invention is made of hot gas electricity generating section 201, charging part 202 and battery 203.
Hot gas electricity generating section 201 can comprise based on Seebeck effect (Seebeck effect), produces the thermoelectric element (thermoelecric module) of electromotive force.Thermoelectric element among the present invention comprises following structure: a pair of ceramic wafer up and down; On the ceramic wafer of above-mentioned top and the bottom, the 1st and the 2nd thermoelectric pottery plate of Xing Chenging respectively; Between the above-mentioned the 1st and the 2nd thermoelectric pottery plate, N type semiconductor that provides alternately and P type semiconductor.
1821, the Seebeck (Seebeck) of Germany was if found copper (Cu) line and bismuth (Bi) line, and two edge tails of bismuth wire and antimony (Sb) line are welded to each other, and the heating connecting portion will produce potential difference, the phenomenon that electric current flows occurs.Because this phenomenon is to utilize temperature difference to produce voltage, that is, utilize temperature difference to produce hot gas electric power (thermoelectromotive force), electric current flows in closed circuit, is the principle of thermoelectric power generation, and we are referred to as Seebeck effect.Usually, according to the kind of metal, with the free electron of the distinctive energy moving metal of temperature inside.
Even the metal of identical type, because contact is high temperature different with electron energy low temperature, electronics moves to a direction, produces potential difference, produces hot gas electric power.
Fig. 3 is based on operable Seebeck effect among the present invention, the oblique view of an example of the thermoelectric element 300 of generation hot gas electric power.As shown in Figure 3, thermoelectric element 300 is made of following components: form the 1st thermoelectric pottery plate 302 on the 1st ceramic wafer 301; On the 1st thermoelectric pottery plate, N type semiconductor 303 and P type semiconductor 304 are set alternately; At N type semiconductor 303 with above the P type semiconductor 304, set gradually the 2nd thermoelectric pottery plate 302 ' and the 2nd ceramic wafer 301 '.
Utilize the temperature difference at two ends when thermoelectric element 300, carry out hot when mobile to the low-temperature end position from the temperature end position, N type generating element (N type semiconductor 303) and P type generating element (P type semiconductor 304) move from temperature end electronics and electric hole (hole) respectively to low-temperature end, generate electricity.In order to carry out the generating of thermoelectric element, at the two ends of conversion element, have enough temperature differences, the carrier wave of element internal also should move.Charging device of the present invention transmits the heat that the heat radiation accessory in the mobile device produces to the temperature end of thermoelectric element.
As shown in Figure 3, if the 1st thermoelectric pottery plate 302 and the 2nd thermoelectric pottery plate 302 ' two ends between temperature difference (Δ T) appears, for N type semiconductor 303, the electronics that is in temperature end has higher kinergety than the electronics that is in low-temperature end, and the electronics of temperature end keeps than the higher energy state of average fermi level (Fermi level).Therefore, in order to reduce the energy of the electronics that is in temperature end, need spread to low-temperature end, electronics is by moving to low-temperature end, low-temperature end is charged to be " ", temperature end is charged to be "+", the 1st thermoelectric pottery plate 302 and the 2nd thermoelectric pottery plate 302 ' two ends between produce potential difference, we are referred to as Seebeck voltage.On electronics, when the actuating force of the heat that moves when Seebeck current potential and electronics to low-temperature end reached equilibrium, it was in poised state to Seebeck voltage with the directive effect returned to the temperature end of thermoelectricity pottery plate.Like this, the hot gas electric power (thermoelectromotive force) that utilizes the temperature difference (Δ T) between temperature end and the low-temperature end two ends to produce can represent that (Vs) there is following proportionate relationship in its temperature difference (Δ T) with two ends with following mathematical formulae 1.
[mathematical expression 1]
Vs＝αA·ΔT
In above-mentioned mathematical expression, α A is the absolute thermo-electric power of materials A,
Δ T is the low-temperature end of thermoelectric element and the temperature difference between the temperature end.
Because the present invention is not the special main points that constitute with thermoelectric element, omits the detailed description to thermoelectric element here.But if the element of the II-IV family of life cycle rule table, IV-VI family and V-VI family is the compound semiconductor of composition, the conversion efficiency of thermoelectric power generation can access leap and improve.
For mobile device is charged, charging part 202 has the function to the TunePower 203 supply charging currents that are connected charging part.Specifically, charging part 202 can comprise following structure: the direct voltage of the specified level of above-mentioned hot gas electricity generating section 201 outputs is converted to charge DC-DC (DC-to-DC) transducer of direct voltage of needed specified level of TunePower 203 to mobile device.
Battery 203 receives voltage from charging part, to the power supply of each device provisioning certain level of mobile device, then, the action smoothly of above-mentioned each device.
Below, the charging process of the charging device of mobile device of the present invention is elaborated.Comprise the PDA of mobile phone (Personal Digital Assistant: personal digital assistant) inside of various mobile devices such as, load the abundant chip of heat dissipation capacities such as CPU, CDMA module.If start mobile device within a certain period of time, the heat radiation accessory of mobile device inside produces heat.At this heat radiation accessory and remove between the heating panel of heat, connect the hot gas electricity generating section 201 that is arranged on above the heat radiation accessory and utilize temperature difference between temperature end and low-temperature end two ends, generation hot gas electric power.Utilize heat, the hot gas electric power of generation transmits to the charging part 202 of mobile device inside.Charging part 202 is converted into the charging voltage of mobile device, and each device for the driven mobile device that utilizes conversion charges to battery 203.
