Background technique
Traditional fuel energy is reduced day by day, it is endangered caused by environment becomes increasingly conspicuous.Currently, China has seven
Necessarily without electric population far from grid power system.Sight renewable energy is invested all in the current whole world, it is desirable to renewable energy
Source can change the energy resource structure of the mankind, the energy for providing sustainable development, can also solve the problems, such as going to the countryside for distributed power generation.
The evolution history of generation technology includes the turbogenerator of traditional water wheels driving, and steam-powered generator is interior
Fuel engine power generation engine and the turbogenerator of natural gas driving burn the turbogenerator of coal and the steam whirlpool of atomic energy driving
Turbine generator.All above-mentioned these all can lead to huge environmental disruption such as: flooding of rivers, air or water pollution.With regard to this ring
Guarantor's problem, we must do the reduction method energy-saving emission-reducing of the earth, it is made to meet the energy requirement of macro environment environmental protection.In field and far
The activities such as extra large operation, scientific investigation, exploration, rescue are frequently necessary to portable power supply, such as electric power storage of currently used portable power
Pond, diesel-driven generator or folding photovoltaic panel etc. have certain limitation in use.For example, the capacity of battery is limited, power supply
It cannot continue;Diesel-driven generator is inconvenient to carry, needs to consume fuel.Collapsible photovoltaic panel can not be in night use.
In existing technical solution, have by the way of solar energy thermal-power-generating.Flat plate collector is by solar energy middle finger standing wave
The thermal energy of section is collected, and thermal energy is transferred to by heat-transfer device the hot end of thermoelectric chip later, and thermoelectric chip cold end dissipates

Plain simple substance is raw material, is synthesized using technologies of preparing such as condensation, powder sintering, films, this just increases technical difficulty and production
The quality risk of product.
3) processing step is more, and some technique is led across multiple technologies such as materials synthesis, precision machinery processing and microelectronics
Domain, product quality management are not easy to carry out.
4) some processes are more demanding to the technical level and qualification of operator, and operation cost is high.
5) existing microelectronic technique is produced on Minitype thermoelectricity module and asks using upper generally existing effective heat transfer area is low
Topic, causes power density generally lower.
In the past 20 years, the miniaturization technologies of electrothermal module receive more and more extensive pass because of its unique application background
Note.Beauty, moral, Deng state develop the technical solution of a variety of electrothermal modules micromations in succession, and be applied to portable power,
The fields such as submarine detector, gas sensor and medical instrument.Past solution is to carry many batteries in outlying district;
However there is much more convenient solution to outlying district now.Even if people are now using each without grid power system
Kind of heat resource power generation underground heat, industrial waste heat, waste incineration, mine waste heat, atomic energy waste heat and burning hot etc..In addition, in fire
