The superconduction heat absorbing sheet
Technical field
The present invention relates to a kind of superconduction heat absorbing sheet, be applied to field of solar energy.
Background technology
Heat-absorbing plate core commonly used all adopts band or whole plate welding upper runner to combine basically in the flat-plate solar collector industry field at present; Though also adopt super heat-conductive pipe; Collecting efficiency increases; But, make that runner 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 runner 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 conduction speed is slower, efficient is poor, reduces 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, combination is insecure; 5, freezing tolerance is poor.
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 superconduction heat absorbing sheet.
It is this superconduction heat absorbing sheet that the present invention solves the problems of the technologies described above the technical scheme that is adopted; Comprise aluminium base; Its design feature is: the below of said aluminium base is provided with and aluminium base all-in-one-piece superconduction runner; Said superconduction runner, the both sides of said aluminium base are respectively arranged with public draw-in groove and female draw-in groove, are provided with superconductive medium in the said superconduction runner.The incorporate setting of superconduction runner can effectively reduce heat loss, and thermal-arrest speed is also faster.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.
Aluminium base upper surface of the present invention is provided with selective heat absorbing coating.Can better absorb energy.
The inner surface of superconduction runner of the present invention is provided with backflash.Backflash has guaranteed the quick backflow of superconducting fluid.
The material of aluminium base of the present invention is 3003 rustproof aluminum alloys.
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, effectively reduces the radiation loss in the heat conductive process.Assembly unit is simple, convenient, and combination is flexible, and speed is fast.

The specific embodiment
Below in conjunction with embodiment the present invention is done further detailed description, following examples are to explanation of the present invention and the present invention is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment is made up of aluminium base 1, superconduction runner 2, selective heat absorbing coating 3, aluminium base 1 and the 2 integrated settings of superconduction runner; By the extrusion modling of mould one; Material selection 3003 rustproof aluminum alloys, front are coating for selective absorption 3, and the back side is superconduction runner 2.Superconduction runner 2 quantity of every superconduction heat absorbing sheet are calculated the back setting according to endotherm area and heat transfer efficiency, and present embodiment is provided with a superconduction runner 2.
Be provided with superconductive medium in the superconduction runner 2, in superconduction runner 2, be provided with backflash 6.Two edges of aluminium base 1 are respectively arranged with public draw-in groove 4, female draw-in groove 5, and different superconduction heat absorbing sheets lean on public draw-in groove 14 each other to cooperatively interact and link together with female draw-in groove 15.
Superconductive medium according to the invention is a superconducting fluid.
Embodiment 2: as shown in Figure 2, and the structure basically identical of present embodiment and embodiment 1, difference is that the superconduction runner 2 of present embodiment is provided with two groups.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, characteristic and principle are done, include in the protection domain of patent of the present invention according to patent of the present invention.Person of ordinary skill in the field of the present invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from structure of the present invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
