The energy is the basis of human survival, and the reasonable development of the energy and utilization are the sources of entire society's development, also is one of important symbol of human civilization and progress.Along with the progress and development of social production, along with the raising of living standards of the people, energy demand also will increase substantially.Yet the development and utilization of the energy is subjected to the restriction of numerous factors such as resource, technology, economy and environment.Solar energy does not produce the new forms of energy of pollution as a kind of to environment, and is inexhaustible.Solar energy is to reduce the effective way that conventional energy resource consumes, and vast potential for future development is arranged in building field.The solar energy utilization has been combined as major tasks with building in the world and carried out.Solar water heater is with the solar energy optical-thermal conversion, utilizes greenhouse effects and siphon principle to make the device of water heating, because it does not consume fossil fuel, pollution-free, price is lower, and is safe and convenient to use.In the solar energy optical-thermal transfer process, key is that the radiant energy with the sun is converted to heat energy, because solar energy relatively disperses, must manage it is put together, so heat collector is the various key equipments that utilize solar energy equipment.
The common heat collector of China mainly contains two classes at present: flat-plate collector and vacum tube-type heat collector.Flat-plate collector selects flat heat collecting plate, light transmissive material cover plate, heat-insulation layer, housing and the water inlet pipe and water outlet pipe of absorbing coating to form by scribbling, when sunshine impinges upon on the flat heat collecting plate through glass, wherein most of solar radiant energy is absorbed by absorber, change heat energy into, and the working medium of biography in the fluid passage, by Natural Circulation or forced circulation, and the water in the storage tank is heated, though flat type solar heat collector is simple in structure, efficient is high, but, make that its heat insulating ability is relatively poor owing to reasons such as manufacturing technologies; The vacuum type heat collector comprises full-glass vacuum collector, heat-tube vacuum collector, through type metallic object vacuum collector.
(1) the annual thermal efficiency height of full-glass vacuum collector, its cost, freexing tolerance, night insulation are between heat-tube vacuum collector and flat-plate collector, but its bearing capacity is lower, heat-resistant impact ability is relatively poor, might burst the relatively poor (tracheal rupture of system reliability after the water filling of empty solarization system, the whole system maintenance of need stopping using), easily fouling in the glass tube after use a period of time, difficult cleaning has had a strong impact on its thermal efficiency.
(2) the annual thermal efficiency of heat-tube vacuum collector is higher, and bearing capacity is big, but general pressure-bearing 0.98MPa, thermal shock resistance is good, anti-freezing, night, heat loss was little, the system works good reliability, but cost an arm and a leg, market is difficult for accepting, and the easy fouling of condensation end needs periodic cleaning, be subjected to the restriction of cycle fluid in the heat pipe service life, thermal conversion efficiency reduces along with the increase of access times.
(3) the thermal efficiency height (winter 45% of through type metallic object (copper pipe) vacuum collector, summer 80%), pressure-bearing height (the highest 0.98Mpa), the heat collector non-scaling, good reliability (metal heat shock resistance), the thermal power of single tube is higher by 21% than unidimensional all-glass vacuum tube, but since the sealing-in of glass and metal employing be rubber seal, so its vacuum is difficult to lastingly.
