Description
Technical field
The present invention relates to heat collector, relate in particular to a kind of nano-fluid solar window type heat collector.
Background technology
Be accompanied by the progress of human society, the contradiction of man and nature more and more seriously is embodied in the huge energy resource consumption.China is energy-consuming big country, and energy for building has occupied 27.8% of national total energy consumption, is that main usefulness can the rich and influential family.Tapping a new source of energy, adopt the new energy materials technology to carry out building energy conservation plays an important role to the social total energy consumption that reduces China.(1) in numerous regenerative resources the solar energy clean environment firendly, contain that energy is huge, ubiquity and be applicable to the building energy supply, and China land year is accepted solar radiant energy 3.3 * 10
3～8.4 * 10
6KJ/ (m2), wherein 2/3 area with last year sunshine time greater than 2200h, solar energy resources is abundant, aspect the building energy supply bigger advantage is being arranged.(2) in the novel energy material, nano particle is because particle size and conduction electron de Broglie wavelength and superconducting state moral coherent wave surplus reason size are suitable even littler, the boundary condition of its periodic property is damaged, bigger variation (small-size effect) has taken place in the optical absorption characteristics of nano particle and common material, the surface that diminishes (or interface) effect owing to nano particle diameter sharply increases simultaneously, make the optical property of nano particle that marked change take place, the phenomenon of absworption peak blue shift and red shift and absorption band broadening occurred.Thereby alloy granular solids has special optical absorption property and has produced strong photo-thermal characteristic, and nano material has important effect as novel solar energy materials to improving the solar energy optical-thermal transformation efficiency.
