Embodiment
By reference to the accompanying drawings the present invention is elaborated below by embodiment:
Shown in the structural representation of figure (1) and figure (2): in the monomer of electrolyte thermoelectric cell device, at least be surrounded by and contain inert electrode A[1], inert electrode B[2] and electrolyte colloidal sol [3], by inert electrode A[1] and inert electrode B[2] consist of certain place gap at the auxiliary lower interval of insulated enclosure shell [6], in this spatial joint clearance, fill with needed electrolyte colloidal sol [3], electrolyte colloidal sol is closely merged with two inert electrodes to be connected, just consisted of the basic structure body of electrolyte thermoelectric cell, this structure is similar to the chemical primary cell structure substantially, electrolyte solution is arranged, positive and negative polarities are arranged.Just be not admit of chemical reaction to produce in the electrolyte thermoelectric cell, inert electrode A[1 in the battery] and inert electrode B[2] a positive and negative difference when not having the temperature difference, do not had, only have inert electrode A[1] and inert electrode B[2] just demonstrate their positive-negative polarity feature when having the temperature difference, therefore, the electrolyte thermoelectric cell here is to belong to physical battery.
Shown in the operation principle schematic diagram of figure (3): on a complete electrolyte thermoelectric cell, if to inert electrode A[1] apply certain heat Q, make its rising uniform temperature, make simultaneously inert electrode B[2] remain on radiating state, like this so that remain certain temperature difference between two inert electrodes, just can between two inert electrodes, obtain certain temperature electrical potential difference, connect external circuit and draw just energy extracted current I of pile crown [5], thereby realize the conversion of temperature difference electric energy.
In practice, as long as can make these two electrodes keep needed temperature difference, can both make between corresponding electrode and produce electrical potential difference, and specifically high which temperature of which electrode temperature is not low, that is to say, inert electrode A[1] with inert electrode B[2] be fully equivalence in chemical property, the electrode positive-negative polarity is at last by the poor decision of both actual temperatures.
In addition, can cause the change of electrolyte colloidal sol generation volume in the airtight container because of variations in temperature, this because of the pressure of change in volume to the airtight container generation in order to alleviate, a slow pressure device [4] made from seal tube just is installed in cell body, this still carries out the passage of regular maintenance to battery cylinder electrolyte colloidal sol [3] simultaneously, thereby can guarantee for a long time the quality of the use of electrolyte thermoelectric cell.
Used so-called inert electrode in the electrolyte thermoelectric cell only refers to otherwise with intrinsic electrolyte colloidal sol [3] the solid conduction material of chemical reaction occurs.But in order to guarantee the manufacturing cost degradation of electrolyte thermoelectric cell device product, the inert electrode material that here adopts is the electrode of the general common relatively cheaply solid conductive material made such as material with carbon element (comprising graphite, indefinite form carbon) and ferrous material (comprising stainless steel).
Employed electrolyte colloidal sol [3] in the electrolyte thermoelectric cell is exactly our usually said colloidal electrolyte, is to prepare with our common several industrial chemicals.According to the experiment gained, different chemical compositions and different proportional arrangement, in the electrolyte thermoelectric cell, will form different thermoelectric forces and change system, therefore, in order to obtain the most effective thermoelectric force, electrolyte colloidal sol [3] preparation composition must be according to different thermals source and temperature difference zone concrete decision.In addition, be mixed with colloidal sol and also have a purpose, slow down exactly heat transfer speed between two electrodes, it is poor to improve the two poles of the earth relative temperature, thereby improves the conversion efficiency of thermoelectric of electrolyte thermoelectric cell.
More than just the basic building block of electrolyte thermoelectric cell forms, but existing around us is that heat resource form is diversified, the existing sun is directly given our thermal source, the thermal source that also has day and night temperature to form, the fuel combustion thermal source, geothermal heat source etc., if will effectively collect these thermals source, just must there be effective contour structures to adapt to these our needed energy source, therefore electrolyte thermoelectric cell device contour structures also requires varied, both can be designed to plate armature, also can be designed to tubular structure, to adapt to the demand in different-energy source, such as figure (4), shown in the figure (5), be exactly electrolyte thermoelectric cell tubular type monomer structure schematic diagram, this structure not only can satisfy the solar radiation temperature difference and turn electric demand, can also satisfy the temperature-difference thermoelectric conversion that other fuel mode of heating produces.
Shown in figure (7), it is electrolyte thermoelectric cell monomer operation principle circuit diagram, record according to repeatedly testing, its main thermoelectric potential difference is to be produced by Seebeck (Seebeck) effect, lower in electrolyte thermoelectric cell monomer work output voltage, generally about several volts of zero points, usually can not satisfy the demand of the actual electricity consumption of people, therefore in practice, to form a lot of monomers by a fixed structure and combine, then use the serial or parallel connection circuit to contact into an integral body, form an integrated thermal electric conversion electric power, shown in figure (8), be many monomer electrolytes thermoelectric cell series circuit, can improve thus the whole output voltage of electrolyte thermoelectric cell, figure (6) is the flat monomer integrated morphology of electrolyte thermoelectric cell schematic diagram, device combination by a large amount of like this just can realize that the direct cheapness of " rudimentary " heat energy is converted to the purpose of practical electric energy; The electrolyte thermoelectric cell of tubular structure adopts the mode of such integrated combination too, can reach same thermal energy collecting conversion effect.
