Description
Technical field
This utility model relates to solar energy heat utilization field, particularly relates to a kind of all-glass heat pipe vacuum solar heat collector.
Background technology
Complete glass vacuum sun thermal-collecting tube is the core component of heat collector.Existing complete glass vacuum sun thermal-collecting tube is overall
As one elongate inner flask, be specifically made up of with cover glass tube two inner glass tubes being set in together, inner glass tube and
It is evacuated between cover glass tube, in outside deposition solar energy selective sorbent surface, coating or the film system of inner glass tube, constitutes
Absorber, is converted to solar energy heat energy with this, thus heats the heat-transfer fluid in inner glass tube.All-glass vacuum solar collection
Inner glass tube in heat pipe is arranged concentrically with cover glass tube, uses single-ended open design, the inner glass tube of its one end and cover glass
Pipe uses annular sealing by fusing, and the other end is airtight hemispherical, and is provided with the support card of band getter, absorber inner glass tube hemisphere
Shape is bearing in cover glass tube hemispherical end, forms the free end of thermal expansion, the all-glass vacuum solar collection caused during buffering work
The thermal stress of heat pipe open end.
In use there are problems in the heat collector of this complete glass vacuum sun thermal-collecting tube, the most topmost
Problem is exactly complete glass vacuum sun thermal-collecting tube internal memory water excess, causes the water in complete glass vacuum sun thermal-collecting tube to heat up slow
And then make whole system circulation rate slack-off slowly,.Owing to the hot water in complete glass vacuum sun thermal-collecting tube cannot take out completely, institute
With when complete glass vacuum sun thermal-collecting tube caliber is the thickest, pipe range is the longest, it is impossible to the water of taking-up is the most more, causes the thermal-arrest of system
Efficiency reduces.
In recent years, all-glass heat pipe vacuum solar heat collector is more and more universal, and its core component all-glass heat pipe vacuum is too
Sun thermal-collecting tube, is to dock the airtight glass tubing in an one end at the mouth of pipe of complete glass vacuum sun thermal-collecting tube, docking glass tubing with

Heat pipe condensing tube, is coated with the inner tube of coating for selective absorption as heat pipe evaporator section, i.e. heat exchange segment, when evaporator section absorbs the sun
When radiant heat energy is heated, heat-transfer working medium carburation by evaporation, steam flows to condensing tube with the velocity of sound under differential pressure action, and discharges heat energy
After condense into liquid, liquid flows back to evaporator section along inner pipe wall again, so goes round and begins again, it is achieved utilize solar energy heating.
This all-glass heat pipe vacuum solar collector pipe condensing tube is oversize, causes header sectional dimension bigger than normal, manufactures more tired
Difficult；The total moisture storage capacity of water heater of this all-glass heat pipe vacuum solar collector pipe composition is than complete glass vacuum sun thermal-collecting tube hot water
Device is a lot of less, and theoretical efficiency should be the highest, but because glass is the non-conductor of heat, heat conductivity only 1.2 W/mk, leads for copper
The some thousandths of of hot coefficient, has a strong impact on condensing tube release heat.
As can be seen here, above-mentioned existing all-glass heat pipe vacuum solar collector pipe in structure and uses, it is clear that still suffer from
There are inconvenience and defect.Found a kind of novel all-glass heat pipe vacuum solar collector pipe, and design novel heat collector simultaneously so that it is
Have more practicality, become technical problem urgently to be resolved hurrily.
