The super heat-conductive pipe flat-plate solar collector
Technical field
The present invention relates to a kind of super heat-conductive pipe flat-plate solar collector.
Background technology
The sprue of plate core commonly used all adopts straight tube in the flat-plate solar collector industry field at present; Though employing superconductive medium; Collecting efficiency increases; But, make that sprue and water tank heat exchanger effectiveness are not high because heat transfer efficiency that structure is limit is not very high, from face the superiority of flat-plate solar collector can better not shown.On the other hand the heat of sprue by heat-absorbing plate core through welding or the whole crimping conduction that links to each other with super heat-conductive pipe; But because heat pipe is that the overheated conduction of turned is passed to sprue; Conduction certainly will have thermal resistance to produce indirectly; So heat transfer efficiency is poor, reduce to some extent for the heat absorption of heat-absorbing plate core.Owing to above two reasons, adopt the heat collector of prior art that following some deficiency is arranged thereby make: 1, thermal-arrest speed is slower, and heat transfer efficiency is not high; 2, radiation loss is bigger in the heat conductive process; 3, production cost is too high; 4, anti-freezing property is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reasonable in design, heat loss is few, the thermal efficiency is high, thermal-arrest speed is fast, cost is low, safe and reliable super heat-conductive pipe flat-plate solar collector.
It is this super heat-conductive pipe flat-plate solar collector that the present invention solves the problems of the technologies described above the technical scheme that is adopted; Comprise glass cover-plate, rubber seal, housing, its design feature is: be provided with interconnected superconduction heat absorption one plate core and sprue in the described housing, in sprue, be provided with the sprue hole; The below of said superconduction heat absorption one plate core is provided with insulating; The below of said insulating is a backboard, and said backboard links to each other with housing, and said superconduction heat absorption one plate core is made up of superconduction heat absorption one plate; The top of said superconduction heat absorption one plate is an aluminium base, and the below of said aluminium base is the superconduction runner.The superconduction runner contacts with the direct of sprue, can effectively reduce heat loss, and thermal-arrest speed is also faster.
The aluminium base of superconduction heat absorption one plate of the present invention is provided with selective heat absorbing coating.Can better absorb energy.
The both sides of superconduction heat absorption one plate of the present invention are respectively arranged with public draw-in groove and female draw-in groove.Public draw-in groove and female draw-in groove of different superconduction heat absorption one plates are worked in coordination, and be easy to connect, quick.
The inner surface of superconduction runner of the present invention is provided with backflash.Backflash has guaranteed the quick backflow of superconducting fluid.
Sprue of the present invention is provided with the heat pipe convex tendon in the hole, and said heat pipe convex tendon one end stretches out from the bottom in sprue hole, and the other end is positioned at the middle part in sprue hole.
Heat pipe convex tendon of the present invention is respectively left heat pipe convex tendon, middle heat pipe convex tendon and right heat pipe convex tendon.
The edge of sprue of the present invention is provided with slot, and said slot and superconduction heat absorption one plate core are complementary.
The present invention compares with prior art and has the following advantages and effect: reasonable in design, simple in structure, with low cost; Anti-freezing property strong (--50 ℃), the production equipment less investment, operating efficiency improves; Thermal-arrest speed is fast, improves the thermal efficiency, and national standard is day to get heating rate 7MJ/M2 at present; External like product is 8MJ/M2, and this product Ri Dere is 12MJ/M2, effectively reduces the radiation loss in the heat conductive process.
