And for example publication number is CN102200352A patent application, relate to a kind of solar thermal collector, comprise solar heat permutoid and chamber is characterized in that: solar heat permutoid comprises a feed liquor house steward and a fluid house steward, and they are at least linked up by two endothermic tubes by they; The heat-absorbent surface close contact of one piece of absorber plate and each endothermic tube; Described chamber is vacuum chamber, and solar heat permutoid is placed in vacuum chamber; Vacuum chamber is made up of panel, base plate and the metal frame along their peripheries, and panel is glass, and base plate is glass or metallic plate, and described glass periphery is the metal tape sticked to one, and described sealing is the welding by panel and floor peripheral metal material; The positioner of locating support and supporter composition is provided with between panel and base plate; Supporter is fixed by locating support, and supporter is supported in panel and base plate through the corresponding aperture in absorber plate.Although this application to heat insulation effect with certain raising effect, complex structure, heat collector thickness is large.
Summary of the invention
In order to solve the problems of the technologies described above, provide the vacuum flat-plate solar collector that a kind of high insulating effect, thickness are thin.
The present invention realizes above-mentioned technical purpose by following technological means.
Vacuum flat-plate solar collector, comprise shell, be positioned at absorber plate and the endothermic tube of enclosure, described endothermic tube is positioned at absorber plate bottom, described endothermic tube is flat copper pipe and has water inlet and delivery port, and described shell is made up of transparent panel and base plate, and described transparent panel is connected with the edge seal of base plate, middle part is supported by supporting component, described water inlet and delivery port extend to beyond shell and base plate through base plate and are tightly connected, and described enclosure is vacuum state.
Preferably, described endothermic tube is supported by endothermic tube support, and described endothermic tube support is between base plate and endothermic tube.
Preferably, described transparent panel is low iron safety glass, and described absorber plate is plated film aluminium sheet.
Preferably, described supporting component is made up of the first support column cooperatively interacted and the second support column, and described first support column is between base plate and absorber plate, and described second support column is between absorber plate and transparent panel.
Preferably, described first support column is PI(polyimides) post or glass column, described in be the second support column glass column.
Preferably, described shell edge is provided with safe edge and corner protector.
Vacuum flat-plate solar collector of the present invention, on the one hand, directly vacuumizes enclosure, the heat stopping endothermic tube outwards conducts, and reduces the loss of heat, accomplishes maximum insulation, solve the disadvantage of heat insulation effect difference, heat insulation effect significantly improves.Meanwhile, compared with existing vacuum flat plate collector, simplify the structure of shell; On the other hand, endothermic tube is adopted as flat copper pipe; Substantially reduce the thickness of flat plate collector, gross thickness reduces 3/4, reduces to 20mm from 80mm.The simplification of structure also makes the weight of described flat plate collector obtain significantly to reduce in addition, and the weight of flat plate collector of the present invention decreases 1/4 compared with existing flat plate collector gross weight.
