Description
Technical field
The present invention relates to utilize the collecting apparatus field of solar energy, be specially a kind of integral solar flat-plate heat collector.
Background technology
Solar energy is the energy of utilizable clean environment firendly, and is the renewable resource that can continue continuous use.The height of solar energy utilization ratio is decided by solar energy heat collector.The solar thermal collector that uses on the market is flat plate collector greatly at present.Plate solar collector generally comprises thermal-arrest mechanism and framework, and thermal-arrest mechanism is directly installed in the framework.There is following defective in existing flat plate collector: thermal-arrest mechanism is fixed on the chassis base that serves as protective case and Sheng year container, owing to heat collector mechanism directly contacts with base plate, so must cause the part heat to fall by contact site transmission losses such as base plates; Especially making framework need could realize by complicated metal working process, if need cause groove and supporting fin structure, complex manufacturing technology, production cost height; Glass cover-plate directly contacts with heat collector, and is because of glass cover-plate process multiple high temp and cold service, aging easily, repeatedly the deformation meeting weakens sealing effect, causes reducing heat insulation effect, and reduction of service life, existence is leaked, even makes the framework water inlet, influences the life-span of thermal-arrest mechanism.
In addition, existing non-Unitary plate solar collector, because whole framework is contained to carry to rely on and is combined by many, there is the drawback of not enough sealing in the connecting portion of many places combiner, especially infiltration enters in the treadmill body and will take place, cause the supersaturation water steam fog to fill the air in the heat collector flat board, have a strong impact on the illumination fuel factor, residual mist also can corrosion material.
Because existing non-Unitary flat plate collector not have to pay attention at the bottom of framework or limit portion establishes to make to have and intercepts the constant voltage hole that external steam enters,, steam can not be overcome again so entering the interior phenomenon of flat plate collector.The flat plate collector internal cavities is accompanied by temperature and raises and expand what is more, also can be accompanied by the reduction of temperature and shrinks, and this phenomenon repeatedly can make the loose day by day distortion of flat plate collector, and can not continue durablely, also can make fuel factor be tending towards deterioration.
The catheter inwall ubiquity of existing plate solar collector the phenomenon that incrustation scale gathers.Incrustation scale confesses with the magnesium that has in the hard water, calcium plasma focus and forms that incrustation scale can cause heat localization and heat conducting serious hindrance, also is the major reason that causes the liquid tracheal rupture.
Summary of the invention
The objective of the invention is the deficiency that exists at the above existing flat plate collector, a kind of long service life, sturdy and durable, the integral solar flat-plate heat collector that can effectively reduce heat loss are provided.
The present invention is achieved in that integral solar flat-plate heat collector, comprises dull and stereotyped housing, and transparent sealing cover plate and thermal-arrest mechanism, thermal-arrest mechanism are installed in the dull and stereotyped housing, is filled with insulation material between thermal-arrest mechanism and dull and stereotyped housing; Cover the transparent sealing cover plate above thermal-arrest mechanism, the transparent sealing cover plate is fixed on the edge of dull and stereotyped housing by press box, is provided with the sealing frame between transparent sealing cover plate and dull and stereotyped housing edge.
The side of described press box and dull and stereotyped housing is fixed by locating pin, and press box, sealing frame and the airtight feud of transparent sealing cover plate are closely linked.
Described dull and stereotyped housing lateral wall is provided with groove, so that when mounted, press box can carry out screens by the cell wall of groove, is convenient to install.
Described dull and stereotyped housing inner bottom part is provided with support, and thermal-arrest mechanism is fixed on the support, avoids the transparent sealing cover plate directly to contact with thermal-arrest mechanism, prolongs the service life of transparent sealing cover plate.
Described dull and stereotyped housing can be for being extended the direct integral structure that the four springs folding of forming forms frame by base plate.
Described dull and stereotyped housing can be reinforced by corner protector for four jiaos.
Described thermal-arrest mechanism comprises thermal-arrest plate and finned tube, feed tube and drain pipe, and the two ends of some finned tubes are communicated as one with feed tube and drain pipe welding respectively, and finned tube closely contacts with the bottom surface of thermal-arrest plate, the formation one.
The mounting means of described thermal-arrest mechanism in dull and stereotyped housing can be that vertical installation of finned tube or finned tube are laterally installed.
Four jiaos of sides of the frame of dull and stereotyped housing are provided with and feed tube and drain pipe corresponding interface, are provided with sealing and fixing cushion rubber pad between feed tube and drain pipe and the interface.
Be equiped with ultrasonic wave antiscale equipment at the mouth of pipe place of feed tube, can prevent finned tube, feed tube and drain pipe encrustation effectively behind the ultrasonic wave antiscale opening of device.Because incrustation scale can have a strong impact on Heat-collecting effect and heat transfer, the long-pending thick meeting of incrustation scale causes the danger of booster.The incision of ultrasonic wave function can strengthen heat exchange.
The outer frame bottom of described flat board is provided with the constant voltage hole that has disposed moisture absorption silica gel mesh bag particle; be beneficial to space and appropriate being communicated with of extraneous maintenance in the flat plate collector; thereby can keep an atmospheric intrinsic pressure in the flat plate collector; prevent when air humidity is big; humidity in dull and stereotyped is controlled; guarantee that transparent sealing cover plate internal face can freezing dewfall phenomenon not take place because of air contains supersaturated vapor; can effectively reduce simultaneously when pH value forming, thereby the protection heat absorbing coating is avoided corrosion less than 7 the acid globule that is.
Described transparent sealing cover plate can be transparency glass plate, also can be the fiber focus transparent panel; Transparency glass plate can be float glass, safety glass and low iron safety glass.
Described dull and stereotyped housing can be through anodised aluminium, alloy aluminium sheet, galvanized sheet or have 304 stainless steels of Corrosion Protection.
Compared with prior art, the advantage that the present invention has is: dull and stereotyped housing is formed in one, and is simple in structure, and cost of manufacture is low, and heat loss is few, can prolong the service life of transparent sealing cover plate and thermal-arrest mechanism effectively.
