Description
Technical field
The utility model relates to solar radiation transfer devices to utilize technical field, and in particular to one kind is used for through type too
The fluid delivery structure of positive energy heat collector.
Background technique
Solar energy straight pipe is the core component applied in solar energy high temperature collecting apparatus, is both ends open, intermediate true
Empty straight-through vacuum pipe, comprising: surface has the metal tube of coating for selective absorption, and a concentric glass is arranged outside metal tube
Pipe, glass tube and metal tube are by that can cut down material transition sealed attachment；It is vacuumized in glass tube and metal tube interlayer, glass is effective
In the coating for selective absorption of protection metal tube surface, while reducing collection heat loss.
When heat-collecting temperature increases, solar energy straight pipe expanded by heating, since the coefficient of expansion of metal and glass is inconsistent,
In general the linear expansion coefficient of metal an order of magnitude higher than glass, so for the vacuum heat-collecting using fixed sealing structure
For pipe, expansion of metal rate is higher than glass swelling rate, may cause glass tube by metal tube spalling, or even accident occurs.
It is poor to make up the line swell increment between metal and glass that expansion joint is mostly used on the market at present.Expansion joint is for compensation
Because of additional stress caused by temperature difference and mechanical oscillation, and a kind of flexible structure being arranged on container casing or pipeline；Expansion
Section is traditionally also compensator or telescopic joint.By the bellows (a kind of elastic element) and end pipe, branch that constitute its operative body
The attachmentes such as frame, flange, conduit composition.Using effective dilatation of its operative body bellows, with absorption line, conduit, appearance
Change in size or compensation pipes that device etc. is generated by the reasons such as expanding with heat and contract with cold, conduit, container etc. it is axial, laterally and angular
Displacement.It can also be used for noise-and-vibration-reduction, in heat supply, when heat supply pipeline heats up in order to prevent, drawn due to thermal stretching or temperature stress
Pipe deforming or destruction are played, needs that compensator is arranged on pipeline, to compensate the thermal stretching of pipeline, to reduce the stress of tube wall
With the active force acted on valve member or supporting structure.The stress of expansion joint causes mainly due to pressure and displacement.Displacement is drawn
The stress risen is typically larger than stress caused by pressure, it is acted on along the meridian of bellows to (longitudinal direction), generally greater than bellows
The yield stress of material.Pressure causes the film of along the circumferential direction (circumferential direction) effect to be answered on the straight section and ripple of expansion joint
Power forms the membrane stress and folding s tress acted on along meridian direction also in ripple.
CN200810116133 discloses a kind of straight through type vacuum solar energy thermal-collecting tube, and the glass tube and the metal absorb heat
The both ends in gap are respectively arranged with a bellows between pipe, and the outer end of each bellows passes through the institute of a transition rings and the end
State that metal end is integrally welded, the inner end of each bellows connects a coupling tube, and the coupling tube is from the bellows
The metal end for inside passing through, and being pierced by the end is welded on the outer end of the metal heat absorption tube, and the glass tube and the metal are inhaled
It is pumped between heat pipe by exhaust pipe as high vacuum.In endothermic process, the heat of metal heat absorption tube can be absorbed by bellows
Expansion, buffer metal absorbing pipe thermal expansion stresses protect glass-to-metal sealing.
But the complex process of expansion joint, material requirements are high, and volume is larger, according to expansion joint, it is necessary to use heavy caliber
Heat conducting pipe.Therefore, material of the lower stainless steel of cost as heat conducting pipe is commonly used in industry.It is well known, however, that copper
Thermal conductivity is more much better than stainless steel.Why industry does not use material of the copper as heat conducting pipe, cost of the reason in addition to copper pipe
There are one major reasons except very expensive: there are technical contradictions when copper is used in combination with expansion joint.It is embodied as, expands
The material of section generally comprises stainless steel, and the thermal conductivity ratio copper bottom of stainless steel.Use copper pipe as in the case where heat conducting pipe, when
After copper pipe expanded by heating, expansion joint starts to expand not yet, acts on and failing so as to cause expansion joint.For these reasons, industry
Copper pipe is often used without as heat conducting pipe.
To sum up, a kind of fluid delivery structure for straight-through type solar energy heat collector is urgently provided at present, is using copper
Under the premise of pipe is as heat conducting pipe, can effectively solve the problem that copper pipe be heated spalling glass tube the technical issues of.
