Description
Technical field
The present invention relates to flat-plate solar collector, specifically be meant a kind of low cost, legerity type, can intelligence regulate, put freeze, air defense shines the overheated plastic board solar thermal collector that causes system damage, belongs to technical field of solar.
Background technology
As everyone knows, energy problem is one of outstanding problem of facing of the world today, and solar energy is a kind of inexhaustible, nexhaustible clean energy resource.The solar energy optical-thermal conversion is a kind of the most universal, the topmost form that solar energy utilizes in the present world wide, and wherein the most representative is exactly solar water heater.China has become and has produced the maximum country of solar water heater in the world, also has maximum in the world Solar Heater Market simultaneously.
The solar thermal collector of having widely applied mainly contains electron tubes type solar thermal collector and flat type solar heat collector, wherein the electron tubes type solar thermal collector still accounts for domestic heat collector market more than 85% at present, and abroad, then on the contrary, flat plate collector has accounted for the share of heat collector market more than 90%.Trace it to its cause, still be that mainly at present domestic flat plate collector cost is still too high, compare with very ripe electron tubes type solar thermal collector, have very big inferior position on the price, therefore more favored not as tubular type collector cheaply on the contrary on the market at home.
Yet along with the quickening of domestic city process, it is fewer and feweri that the chance of vacuum tube collector is left in the emergence of villa, high level and little high level for, and the continuous development of hot water engineering also requires to popularize panel solar.Use for reference external experience, resolve solar energy and architecture-integral problem effectively, panel solar should be first-selected.And the per day efficient of flat type solar heat collector is than electron tubes type solar thermal collector height, and its bearing capacity is strong simultaneously, endotherm area is big.Because flat plate solar water heater separates with storage tank, combine more flexibly, more perfect with building, realize and architecture-integral alternative roof panels, wallboard etc. easily, also saved corresponding construction material expense simultaneously, more had superiority thereby flat-plate solar collector is applied to heavy construction.Therefore, from the development trend of solar energy collector, the flat solar water heater has huge development potentiality,
The too high main cause of flat plate collector cost is that present flat plate collector adopts high copper coin of price or aluminium sheet material mostly, and mostly need to adopt ultrasonic spot welding or high-frequency welding that metallic water pipe is welded on the heat collector sheet material, thereby cause cost to promote further.
In addition, directly be the atmosphere intercommunication between present flat plate collector cover-plate glass and the baffle core, convection current heat conduction is so just unavoidably arranged, thus large tracts of land heat radiation on the monoblock cover plate, heat-insulating property is relatively poor, causes the decline of the hot collecting efficiency of heat collector.Simultaneously, be different from vacuum tube collector, at present common flat plate collector itself does not have antifreeze function, easily causes freezing of water in the heat collector when use the winter of severe cold, not only influenced the normal operation of heat collector, in case and the icing spalling that very easily causes thermal-collecting tube in the water pipe.
Because flat plate collector itself does not have the intelligent antifreeze thermal characteristics of preventing, therefore, at present the flat plate collector solar energy system adopts vacuum solenoid find time aqueduct, Constant Temperature Circulator constant temperature circulation bobbin carriage water source or adopt heater by service such as anti-return emptier usually.In cold countries and regions of northern China and other winters, for ensureing that water heater normally uses when temperature is lower than below 0 ℃, usually take to aqueduct be equipped with electric-heating belt energising insulation, dress with vacuum solenoid find time aqueduct, adopt Constant Temperature Circulator constant temperature circulation bobbin carriage water source or adopt heater by services such as anti-return emptier, otherwise solar water heater can't use " hibernation ".These become the requisite auxiliary configuration of present stage flat plate solar water heater by external force to hydraulic pipeline " antifreeze ", but the further increase of cost be the more important thing is and caused to the difficultyization that this has caused the complicated of system on the one hand and has safeguarded on the other hand.And in the summer of sweltering heat, present flat plate collector structure can make heat collector be in empty solarization state just in case run into the situation of cutting off the water, and causes collector system overheated, and some parts are impaired, seriously shortened the service life of heat collector.
