Description
Technical field
The present invention relates to a kind of rectifier power source, particularly a kind of on the basis of conventional rectification power circuit, the special-purpose AC of in addition improved thermoelectric cooling → DC conversion electric power, its certain loads is thermoelectric pile (refrigerating sheet).
Background technology
Thermoelectric cooling also is called conductor refrigeration, is that famous scientists such as Po Er subsides invented before more than 100 years, and it is known as one of best-of-breed technology that is artificial cooling, heats with pollution-free, noiselessness, cold and hot conversion electric power and be world-famous for always by the mankind.
But when being converted to " peltier effect " (heat energy and heat energy) owing to electric energy in the thermoelectric cooling, conversion efficiency is lower, and the highest have only 68%, thereby power consumption is big especially.And it is to power reguirements quite strict again (being preferably the storage battery power supply), thereby stoped popularizing and development of this technology.Except that the high-power applications of only a few field, can only in small part small-power product, use at present.
The power supply that is generally the thermoelectric cooling power supply has following three kinds: the one, power by storage battery.This supply power mode is better, and the Energy Efficiency Ratio that electric energy is converted to " peltier effect " can reach 68%; But because of the power supply difficulty is big, bad adaptability is only used in extremely indivedual fields.The 2nd, power by Switching Power Supply.This supply power mode except that ripple coefficient near the load request, its AC → DC transfer ratio generally is no more than 70%, the Energy Efficiency Ratio that electric energy (AC) is converted to " peltier effect " is about about 50%.The 3rd, by conventional rectifier power source power supply.It is excessive that this supply power mode is removed ripple coefficient, causes outside " peltier effect " serious decline, and its AC → DC transfer ratio generally is no more than 60%, and the Energy Efficiency Ratio that electric energy (AC) is converted to " peltier effect " is about about 30%.

5Output, according to the basic principle of thermoelectric cooling, the utilization electronic circuit advantage, at the physical characteristic and the conductive characteristic of thermoelectric pile (refrigerating sheet), specialized designs a kind of offered load dedicated network circuit, the main feature of this circuit is:
1, when working, sets up peripheral electrostatic field storehouse for thermoelectric pile.
" peltier effect " proves, the refrigeration of thermoelectric pile (heat absorption) phenomenon and pyrogenicity (heat release) phenomenon, and its essence is exactly that electronics is made travel motion on the conductor of two kinds of different materials.And electronics during to the conductor migration of another kind of material, is having an electron accumulation process from a kind of conductor of material always.In order to accumulate more electronics to be migrated, at first set up an electrostatic field storehouse at the conductor end face, in order to accumulating electronics to be migrated, and the end area of the scale in this electrostatic field storehouse and conductor forms direct ratio.
Under the conductor end area can not condition of enlarged, (commercial hot pile, the end area of its N, P-type material, volume and highly determine), utilize the advantage of electronic circuit, set up a large-scale electrostatic field storehouse artificially, in order to accumulate more electronics to be migrated, and this storehouse is big more, the electronics to be migrated that is accumulated is many more, and thermoelectric cooling (peltier effect) is just good more, obvious more.
For this reason, in this circuit,, increase the electrostatic field storehouse artificially for each sheet thermoelectric pile last electrochemical capacitor in parallel.After measured, under equal electric current, voltage and equal radiating condition, hang down about 5 ℃ than the monolithic temperature that does not add electric capacity when increasing the monolithic temperature (refrigeration) of special-purpose electric capacity.
2, for increasing, thermoelectric pile absorbs circuit.
Thermoelectric pile is by tens of, hundreds of different semi-conducting materials to be in series, to and between, difference between sheet and the sheet is unavoidable, for this reason, the present invention is that every thermoelectric pile, several thermoelectric piles have increased two-way absorption circuit, by local (monolithic) consistent all (several pieces) unanimities that reaches, the thermoelectric pile group is remained under the consistent condition carry out work.
3, utilize other means to carry out dividing potential drop, recurrence, guarantee the consistency that thermoelectric pile is worked under the prerequisite of constant current voltage stabilizing.
Owing to adopted technique scheme, the present invention compared with prior art has following advantage:
1, with improved conventional rectifier power source in addition, but provide the DC power supply of heat supply electricity refrigeration special use, and reached two efficient, that is: AC → DC conversion is efficient, its transfer ratio reaches more than 90%, it is efficient that AC is converted to " peltier effect ", and its efficiency ratio can reach about 100%, is that other similar power supply is incomparable;
2, circuit reduction, design are simple and direct, and components and parts are few, cost is low, on price, all preponderate on useful life.
