Description
Technical field
It the utility model is related to solar energy equipment technical field, and in particular to a kind of to exempt to weld applied to solar thermal collector
Fin.
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
The features such as big, it is one of heat collector type of solar energy and Integration of building optimal selection.When flat-plate solar heat collector works
When, after solar radiation passes through transparent cover plate, it 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, raise the temperature of heat-transfer working medium, the useful energy as heat collector exports.At present, it is conventional
In plate solar collector, its heat absorbing element is formed by welding by thermal-arrest fin with 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.
Utility model content
In order to solve the above-mentioned technical problem the purpose of this utility model is, there is provided a kind of to exempt from applied to solar thermal collector
Fin is welded, this is exempted from, and weldering fin structure is simple, reasonable in design, collecting efficiency is high, and has excellent optical property and weather resistance.
To achieve the above object, the technical solution adopted in the utility model is as follows：
It is a kind of to exempt to weld 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.
Preferably, the circular arc length of described fin is more than quadrant and grown.
Preferably, the absorber is aluminum or aluminum alloy absorber.
Compared with prior art, the utility model has the advantages that：
(1) the utility model has the characteristics that technique is simple, heat transfer area is big, good appearance.
(2) fin of the present utility model is in integrally herringbone, and is formed by two root fins are be hinged, itself and heat collection rack pipes it
Between can between clamping connect, without welding, easy installation and removal, strong adaptability.
(3) fin of the present utility model is round arc, and it is straight to be advantageous to heat collection rack pipes by fin semi-surrounding for heat collection rack pipes
The solar irradiation for absorbing different angle is connect, thermal-arrest, heat transfer efficiency are fairly good.
(4) it is equipped with absorber on heat collection rack pipes and fin of the present utility model, the fin between adjacent heat collection rack pipes
Do 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) the utility model sets coating for selective absorption, and there is selective solar spectrum to absorb optical property, also have
Excellent weather resistance, the optical property still having had under hot and humid environment is operated in, airtight vacuum can also be operated in
Environment or more superior environment, its service life are more superior.

Exempting to weld fin includes fin main body 1 and heat collection rack pipes 2, and the cross section of fin main body 1 is in herringbone, including two chip architectures are identical
And cross section is in the root fin 3 of circular arc；The top of two panels root fin 3 is be 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.
Preferably, the circular arc length of described fin 3 is more than quadrant and grown.
Specifically, the upper surface of on the heat collection rack pipes 2 and fin joint also is provided with one layer of absorber 4.
Preferably, 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 preferred embodiment of the present utility model, be should not be taken to limit of the present utility model
Protection domain, as long as in body design thought of the present utility model and that mentally makes have no the change of essential meaning or profit
