Description
Technical field
The present invention relates to the direct current supply field, refer in particular to fully rationally and the thermoelectric cell that offers the power consumption equipment power supply that can be stable and the electric power system of storage battery and usefulness the electric energy that changes into by sun the subject of knowledge and the object of knowledge.
Background technology
Battery commonly used both at home and abroad at present can be divided into two classes: a class is a storage battery, and another kind of is primary cell, and both respectively have pluses and minuses.Primary cell can change chemical energy into electric energy, when the physical deterioration of participating in reaction arrives to a certain degree, its life-span has just come to an end, the recovery of chemical energy that can't again battery be saved, so claim primary cell again, because refuse battery contains harmful substances such as mercury, cadmium, lead and can cause after the serious environmental disastrous effect, people also feel awkward to how reclaiming and handle that annual hundreds of millions of refuse battery in addition.Simultaneously, people consider actively also that research and development are a series of and can not bring the green battery of harm to environment.Wherein utilize solar energy generation technology not only can avoid the pollution of environment but also can save non-regenerative resource.Thermoelectric cell also is the nearly 2 years focuses of research both at home and abroad, and thermoelectric cell belongs to physical battery, and it is a kind of device that thermal power transfer is become electric energy, its volume is little, long service life (above 20 years), and performance is highly stable, the serviceability temperature wide ranges, and can not cause any type of pollution to environment.
Storage battery is called secondary cell again, and it can not only become electric energy with the chemical energy of deposit, and when the goods and materials of participating in reaction discharge with the form of electric energy finish after, again with charger to its input dc power energy, active material resurrection that again can loss.Therefore storage battery can carry out repeatedly charge and discharge cycle.But the electric power system that storage battery is only arranged because battery capacity is limited, can not be powered for a long time, and the charging interval is long, and filling once electricity needs 4-5 and even tens hours, uses inconvenient, and the charging times of storage battery is limited, arrived useful life and will scrap.
In addition, Chinese patent CN200410054730.6 disclosed " electric power system of solar cell and storage battery and usefulness ", be solar cell and storage battery to be combined power, what its utilized is solar energy generation technology, and its generating efficiency is limited and can only generate electricity daytime.Owing to the measure of anti-backflow is not set, even can causes backflow phenomenon.
Summary of the invention
For fear of with overcome above-mentioned deficiency, the objective of the invention is thermoelectric cell is combined with storage battery, the heat energy that utilizes the sun to produce generates electricity, combine both strong points, remedied both deficiencies, provide a kind of fully rationally and can be stable to the thermoelectric cell of power consumption equipment power supply and the electric power system of storage battery and usefulness.
Realize that technical scheme of the present invention is:
The electric power system of thermoelectric cell and storage battery and usefulness comprises: storage battery, switch, controllable silicon, heat storage tank, female pipe, load, heat exchanger, heat-exchange tube, tube connector, pump, it is characterized in that thermoelectric cell is as generating parts and control assembly, storage battery is as the accumulation of energy parts, heat exchanger posts thermoelectric cell towards sun face, it between heat exchanger and the thermoelectric cell the bigger material of thermal conductivity, preferred aluminum material, the inside of heat exchanger is female pipe, heat-exchange tube, between two female pipes is heat-exchange tube, female pipe is connected with tube connector, tube connector is heat exchanger, pump and heat storage tank couple together, in the pipe water, in the heat storage tank the higher material of heat storage capacity, preferred Na
2CO
310H
2O, the back side of heat exchanger and side, tube connector outer surface, heat storage tank outer surface are surrounded by heat-insulating material, preferred rock wool.The positive pole of two storage batterys is parallel to A point and B point with thermoelectric cell after connecting with a controllable silicon respectively again, and two silicon controlled control utmost points are connected respectively to A point and B point, power to load R by A point, B point again.Load R tandem tap K, whether may command powers to the load.
For improving generating efficiency, can in the thermoelectric cell outside solar cell be set simultaneously, be the electric energy generating with transform light energy.Be connected to the B point after solar cell diode of anodal series connection and a controllable silicon, negative pole is connected to the A point, and the silicon controlled control utmost point is connected to the B point.
Its operation principle is, sunlight at first was radiated on the solar cell and generated electricity daytime, and remaining solar energy sees through thermoelectric cell and is delivered in the heat exchanger, and will exist the temperature difference in the both sides of thermoelectric cell this moment, and thermoelectric cell will generate electricity.The operation principle of thermoelectric cell is introduced in the back.The heat that is delivered in the heat exchanger heats the water in the heat exchanger, and the boiler water circulation that is promoted in the tube connector by pump is got up again, and the heat in the water will be brought to heat storage tank simultaneously, and heat just passes to the Na in the heat storage tank
2CO
310H
2O stores.Night is not owing to there is irradiation of sunlight, heat in the heat exchanger will see through thermoelectric cell and be lost in the atmosphere, thermoelectric cell just can generate electricity once more, because the heat in the heat exchanger makes the temperature of the interior water of heat-exchange tube reduce, density increases, and flows downward, thereby the water Automatic Cycle that promotes in the tube connector is got up, and no longer need to have opened pump, be stored in heat storage tank Na simultaneously
2CO
310H
2Heat among the O will be taken away by the water in the pipe, and water constantly circulates, the generating that thermoelectric cell just can be continuous.
The thermoelectric cell operation principle: thermoelectric cell belongs to physical battery, and it is a kind of device that thermal power transfer is become electric energy.According to Seebeck effect, if two kinds of different metals be connected and form the loop, when the temperature of two joints not simultaneously, because the contact potential difference of two joints, to produce an electromotive force in the circuit, this phenomenon is called thermoelectric effect, and the material with thermoelectric effect is called thermoelectric material.Semi-conducting material often shows higher thermoelectric conversion performance.For semiconductor, if N type and P type semiconductor thermoelectric material are connected together, when the two ends temperature not simultaneously, hole in the P type semiconductor and the electronics in the N type semiconductor then can accumulate to low-temperature end respectively, the load two ends will produce thermoelectromotive force, utilize this principle, be connected, can be made into thermoelectric cell with certain power output and output voltage by p type and n N-type semiconductor N are carried out suitable connection in series-parallel.
Advantage of the present invention is:
(1) simultaneously solar cell and thermoelectric cell are combined, and can generate electricity at daytime and night, can obtain higher energy conversion rate.
(2) electric energy that sun the subject of knowledge and the object of knowledge is changed into by storage battery is fully reasonable and stable offers power consumption equipment.And, reduced the use of battery, also prolonged useful life of storage battery because solar cell and thermoelectric cell provide a large amount of electric energy.
(3) source of electric energy is a solar energy, need not consume the tangible energy, and does not have any type of pollution.
(4) because recirculated water has carried a large amount of heats, so the bursting by freezing and the solar cell burnout phenomenon of pipeline can not take place.
