Abstract
The utility model relates to an improved solar heat collecting tube, which comprises a vacuum tube which is formed by that an outer glass tube and an inner glass tube are separated by a vacuum layer. The improved solar heat collecting tube is characterized in that the inner wall of the inner glass tube is provided with a heating absorbing membrane with a corresponding shape, and the heat absorbing membrane can prevent the heat and the corrosion of medium; heat absorbing medium which is arranged in the heat absorbing membrane can not directly contact the tube wall of the inner glass tube. In the utility model, the heat insulating layer and the vacuum tube are separated, and therefore, the phenomenon that when cold medium is added in the inner glass tube suddenly, the inner glass tube is easy to burst can be avoided; the heat insulating effect and the heat efficiency can be raised, and the cost is reduced.
Description
The utility model relates to the solar thermal collector assembly, and concrete is a kind of modified solar energy heat collection pipe.
Along with the economic construction development, show energy shortage day outstanding.Meanwhile, along with progress of science and technology, the application of solar energy comes into one's own more.The device of gathering the solar energy widespread usage at present is a solar thermal collector, and its main member is a solar energy heat collection pipe, and solar energy heat collection pipe is by the vacuum layer of being made up of glass outer tube and glass inner tube.The glass inner tube outer wall of traditional vacuum heat collection pipe is coated with absorber coatings, and outer printing opacity forms vacuum between inner and outer pipes, plays insulation effect; Outer printing opacity, the internal layer heat absorption, heat-absorbing medium (water or other heat storage) is heated by pipe in glass tube; Because outer wall of inner tube band heat absorbing coating, in the pipe during no heat-absorbing medium, as shine upon, outer tube printing opacity temperature is low, and interior pipe endothermic temperature height is as managing easy explosion in the cold medium of unexpected adding.
Add the pressure-bearing pipe of band absorber coatings in the prior art in addition in glass tube with vacuum, absorbing medium flows in pipe, and its shortcoming is the cost height, and heat-absorbent surface is little, and heat insulation effect is poor.
The purpose of this utility model provides a kind of modified solar energy heat collection pipe, and heat-sink shell is separated with vacuum tube, and glass inner tube easily produces the phenomenon of explosion when avoiding in glass inner tube adding suddenly cold medium, improves the heat insulation effect and the thermal efficiency, reduces cost.
The purpose of this utility model is achieved in that
A kind of modified solar energy heat collection pipe, comprise the vacuum tube of forming by glass outer tube and glass inner tube interval vacuum layer, it is characterized in that: at the inwall of glass inner tube the absorption film of its corresponding heat-resisting, the media-resistant corrosion of shape is housed, heat-absorbing medium is in this absorption film and directly do not contact with the glass inner tube tube wall.
The purpose of this utility model can also realize by following measure:
Described absorption film is cylindric, is close to the inwall that is installed in glass inner tube.
The material of described absorption film can be black plastic film, also can scribble black selectivity absorbing coating for the non-black film.
Described glass-vacuum tube can be both ends open, also can be an end opening.
The utility model has following actively useful effect:
The absorption film of this thermal-collecting tube is installed in interior pipe, and heat-sink shell is separated with vacuum tube, vacuum tube when sky shines in the pipe temperature do not raise yet, can avoid adding suddenly the interior shortcoming of managing easy explosion of cold medium;
The absorption film of this thermal-collecting tube is the material that heat-resisting, anti-heat-absorbing medium corrodes, and price is low, can make with vacuum glass in pipe (both ends open or an end opening formula) identical shape, be close on the glass tube, thermal resistance is little.
Compare with the prior art that the pressure-bearing pipe is housed, this thermal-collecting tube has the heat insulation effect and the higher thermal efficiency preferably.
Now in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model.
Accompanying drawing number:
1. glass outer tube 2. vacuum layer 3. glass inner tube
4. absorption film 5. heat-absorbing mediums
Please refer to Fig. 1, modified solar energy heat collection pipe of the present utility model, comprise glass outer tube and glass inner tube, form vacuum tube between this glass outer tube 1 and the glass inner tube 3 by vacuum layer 2, inwall in glass inner tube is equipped with the absorption film 4 that shape is heat-resisting accordingly, media-resistant corrodes, and heat-absorbing medium 5 is heated in this absorption film 4 and does not directly contact with the tube wall of glass inner tube 3.
In preferred embodiment, described absorption film 4 is cylindric, is close to the inwall that is installed in glass inner tube.
During enforcement, the material of described absorption film 4 can be black plastic film, also can scribble black selectivity absorbing coating for the non-black film.
During enforcement, described glass-vacuum tube can be both ends open, also can be an end opening.
Design feature of the present utility model:
Glass-vacuum tube plays printing opacity, insulation, pressure-bearing effect; Absorbing film plays heat-absorbing action, heatproof, Anti-heat-absorbing medium corrodes, and price is low, can gather materials on the spot. The two is made separately: absorption film can be tight Paste the vacuum glass inner tube, the vacuum tube inner and outer pipe has a narrow range of temperature, and two ends are series and parallel arbitrarily.
Thermal-collecting tube of the present utility model can form various solar thermal collectors.
