For achieving the above object, the utility model adopts following technological scheme:
A thermoelectricity blower, comprises shell, and the front end of described shell offers air blowing opening, and shell front inner wall is provided with electrothermal module and cold junction heat transfer plate, and cold junction heat transfer plate is pressed on electrothermal module on outer casing inner wall; The rear end of shell is provided with blower wheel, and blower wheel drives by the motor of being powered by electrothermal module, offers some air sucking mouths on the sidewall of shell.
Described cold junction heat transfer plate is provided with some for increasing the fin of heat transfer area.
Described motor is arranged on the rear end outer wall of shell, and motor and blower wheel are coaxially installed.
Described shell is the cube structure of overall package.
Between described electrothermal module and motor, be provided with for regulating the control module of electric current.
With respect to prior art, the beneficial effect the utlity model has: the utility model is by arranging electrothermal module, utilize thermoelectric generation technology, thereby the heat energy of heat-producing device is directly converted to electric energy blower impeller operation, air sucking mouth inhale fresh air during impeller operation from sidewall, electrothermal module cold junction is carried out cooling, thereby maintain the maximization of the cold warm end temperature difference of electrothermal module and motor rotation required electric power, guarantee the self-powered continuous firing of thermoelectricity blower.Can meet like this needs of equipment when work combustion oxygenation, can reach again the object of the restriction of breaking away from ABAP Adapter, to improving efficiency of energy utilization, performance equipment guarantee ability is significant.
When the supporting heat-producing device of the utility model is used, the waste heat that utilizes heat-producing device to produce generates electricity, thereby make blower wheel rotation, new wind is blasted to heat-producing device, realized self-loopa utilization, can make heat-producing device break away from the constraint of extraneous power supply unit, improve its efficiency of energy utilization and duty assurance ability.
Accompanying drawing explanation

Fig. 2 is the axial sectional view of the utility model.
Wherein, 1 is air sucking mouth; 2 is shell; 3 is air blowing opening; 4 is electrothermal module; 5 is motor; 6 is blower wheel; 7 is cold junction heat transfer plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, the utility model comprises the shell 2 of cube structure, offers some apertures on the sidewall of shell 2, and air sucking mouth 1, for sucking new wind; The front end of shell 2 offers a macropore, and air blowing opening 3, for the wind in shell 2 is bloated; In the front inner wall of shell 2, be provided with electrothermal module 4, be provided with cold junction heat transfer plate 7 in shell 2, cold junction heat transfer plate 7 is pressed abd fixed on electrothermal module 4 on shell 2 inwalls by bolt.The rear end of shell 2 is provided with blower wheel 6, and blower wheel 6 is driven by motor 5, and motor 5 is arranged on the outer wall of shell 2 rear ends, and motor and blower wheel 6 are coaxially installed.
As shown in Figure 2, shell 2 adopts high thermal conductivity coefficient material to make, and high thermal conductivity coefficient material is specially aluminium or copper.Shell 2 is except for fixing all devices, also as the hot junction heat transfer plate of electrothermal module 4; Cold junction heat transfer plate 7 is pressed on electrothermal module 4 on shell 2, and cold junction heat transfer plate 7 is provided with plate fin above, and plate fin is beneficial to increase heat transfer area.
The hot junction of described electrothermal module 4 and shell 2 close contacts, the cold junction of electrothermal module 4 and cold junction heat transfer plate 7 close contacts, can reduce thermal contact resistance like this.Electrothermal module 4 is connected with control module, control module and motor 5 Integrated designs, control module for electric energy is boosted, voltage stabilizing processes, for motor 5 provides the electric energy that quality is higher.Electrothermal module 4 utilizes the thermo-electric generation of cold and hot end, and the direct current sending is input to control module, after the voltage stabilizing of boosting is processed, for motor provides electric energy.
Working procedure of the present utility model: shell 2 and heat-producing device close contact, when equipment has surplus heat generation, heat passes to the hot junction of electrothermal module 4 by shell 2, hot-side temperature raises, the cold junction of the hot junction of electrothermal module 4 and electrothermal module 4 is poor with regard to formation temperature like this, now electric current produces, electrothermal module 4 starts generating, electric energy boosts through control module, after voltage stabilizing is processed, be transferred to motor 5, motor 5 entrys into service 6 rotations of belt driven blower impeller, extraneous so new wind enters shell 2 inside by air sucking mouth 1, cooling cold junction heat transfer plate 7(cold junction heat transfer plate is because heat is conducted, the factors such as Joule heat, temperature can raise), thereby maintain the temperature difference of electrothermal module 4 cold and hot ends, electric current is constantly produced.New wind is discharged from air blowing opening 3 under the driving of blower wheel 6, sends into heat-producing device, for improving burning oxygen-supplying amount.
