Description
Technical field
The present invention relates to solar energy equipment technical field, and in particular to a kind of to exempt from weldering wing applied to solar thermal collector
Piece.
Background technology
Solar flat-board heat collector is a kind of most basic type in solar heat collector, mainly have absorber plate, transparent cover plate, every
A few part compositions such as thermosphere and shell.Its simple in construction, reliable, cost-effective, also with bearing capacity is strong, endotherm area
Big the features such as, be one of heat collector type of solar energy and Integration of building optimal selection.When flat-plate solar heat collector work
When, solar radiation is passed through after transparent cover plate, is incident upon on absorber plate, is absorbed by absorber plate and change into heat energy, be then passed to
Heat-transfer working medium in absorber plate, raises the temperature of heat-transfer working medium, is exported as the useful energy of heat collector.At present, it is conventional
In plate solar collector, its heat absorbing element is formed by welding by thermal-arrest fin and copper pipe, and its profile is coarse, and contact area is small,
Complex process, fin thermal-arrest heat transfer efficiency is poor, and heat transfer area typically only has 15%, and the welding equipment price of thermal-arrest fin is held high
It is expensive.
The content of the invention
The invention aims to solve above-mentioned technical problem there is provided it is a kind of applied to solar thermal collector exempt from weld wing
Piece, this exempts from weldering, and fin structure is simple, reasonable in design, collecting efficiency is high, and with excellent optical property and weather resistance.
To achieve the above object, the technical solution adopted by the present invention is as follows：
It is a kind of to exempt from weldering fin, including fin main body and heat collection rack pipes, the fin main body applied to solar thermal collector
Cross section is in herringbone, including two chip architectures are identical and cross section be in circular arc root fin；The two panels root fin top hinge
Connect, bottom respectively with adjacent heat collection rack pipes clamping；The upper surface of on the heat collection rack pipes and fin joint also is provided with one layer
Absorber, and the outer surface of the absorber is equipped with a layer-selective absorber coatings；The coating for selective absorption include by
Interior and the intermediate metal, infrared reflecting layer, intermediate metal, cermet coating and the coat of metal that set gradually outside.
Specifically, the heat collection rack pipes are copper pipe, and the fin main body is aluminum or aluminum alloy fin.
It is preferred that, the circular arc length of described fin is long more than quadrant.
It is preferred that, the absorber is aluminum or aluminum alloy absorber.
Compared with prior art, the invention has the advantages that：
(1) present invention have that technique is simple, heat transfer area big, good appearance the features such as.
(2) fin of the invention is in integrally herringbone, and is hinged and forms by two root fins, and it can between heat collection rack pipes
Between clamping connect, without welding, easy installation and removal, strong adaptability.
(3) fin of the invention is round arc, and heat collection rack pipes are conducive to heat collection rack pipes directly to inhale by fin semi-surrounding
The solar irradiation of different angles is received, thermal-arrest, heat transfer efficiency are fairly good.
(4) fin between absorber, adjacent heat collection rack pipes is equipped with heat collection rack pipes of the invention and fin not
Connect, the hot-air radiation in the heat collector below heat collection rack pipes and below fin can also be absorbed well, make monoblock thermal-arrest
Wing has more effectively given play to efficient performance in use.
(5) present invention sets coating for selective absorption, optical property is absorbed with selective solar spectrum, also with excellent
Weather resistance, be operated in the optical property still having had under hot and humid environment, airtight vacuum environment can also be operated in
Or more superior environment, its service life is more superior.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Wherein, reference is corresponding entitled：
1- fins, 2- heat collection rack pipes, 3- root fins, 4- absorbers, 5- coating for selective absorption.
Embodiment
The invention will be further described with embodiment for explanation below in conjunction with the accompanying drawings, and mode of the invention includes but not only limited
In following examples.
The purpose of the present embodiment be to provide for it is a kind of applied to solar thermal collector exempt from weld fin, as shown in figure 1, should
Exempting from weldering fin includes fin main body 1 and heat collection rack pipes 2, and the cross section of fin main body 1 is identical in herringbone, including two chip architectures
And cross section is in the root fin 3 of circular arc；The top of two panels root fin 3 is hinged, bottom is blocked with adjacent heat collection rack pipes 2 respectively
Connect.
Specifically, the heat collection rack pipes 2 are copper pipe, and the fin main body 1 is aluminum or aluminum alloy fin.
It is preferred that, the circular arc length of described fin 3 is long more than quadrant.
Specifically, the upper surface of on the heat collection rack pipes 2 and fin joint also is provided with one layer of absorber 4.
It is preferred that, the absorber 4 is aluminum or aluminum alloy absorber.
Further, the outer surface of the absorber is equipped with a layer-selective absorber coatings 5.
Further, the coating for selective absorption 5 is formed by target power supply sputtering sedimentation, including from inside to outside according to
Intermediate metal, infrared reflecting layer, intermediate metal, cermet coating and the coat of metal of secondary setting.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit the protection model of the present invention
Enclose, as long as the present invention body design thought and mentally make have no the change of essential meaning or polishing, it is solved
Technical problem it is still consistent with the present invention, should be included in protection scope of the present invention within.
