Abstract
Aiming at the potential safety hazard of pipe explosion existing in a conventional evacuated solar collector tube, the utility model provides an explosion-proof type evacuated solar collector tube, i.e., the outer wall of an outer glass tube of a conventional evacuated solar collector tube is attached with a layer of explosion-proof film which has relatively strong stretch resistibility and high light transmittance, and the explosion-proof film wraps the outer wall of the outer glass tube of the whole conventional evacuated solar collector tube. When the pipe explosion of the evacuated solar collector tube happens, the explosion-proof film can greatly reduce the possibility of working substance splash of the evacuated solar collector tube.
Description
Technical field
The utility model relates to solar utilization technique, is specifically related to the technical field of vacuum heat collection pipe in the solar energy system.
Background technology
Vacuum heat collection pipe through the effort of numerous scientific research personnel and numerous enterprises, has been obtained very proud achievement since early 1990s comes out.Over the past two years, the production and selling of vacuum heat collection pipe was all increasing with higher ratio, and shared ratio surpasses 50% already.
As shown in Figure 1, vacuum heat collection pipe has adopted vacuum technique, the convection current and conduction heat waste of gas have been eliminated, and application choice absorber coatings, make the radiation heat loss of vacuum heat collection pipe drop to minimum, the vacuum heat collection pipe solar heat collector can move under middle high temperature like this, also can enlarge application in winter and the low sunshine and the weather changeable area operation of cold district.The inner flask that it attenuates as an elongation, be made up of two coaxial circles glass tubes, be evacuated between inside and outside glass tube, the outer surface of pipe constituted absorber in solar energy selective sorbent surface (coating) was deposited on, with conversion of solar energy is heat energy, the heat-transfer fluid in the heating inner glass tube.The all-glass vacuum solar vacuum heat collection pipe adopts the form of single-ended opening usually, at one end with inside and outside glass tube annular sealing by fusing together.Getter is housed in the vacuum collector.
Higher, anti-freezing, the suitable pressure-bearing of energy of the vacuum heat collection pipe thermal efficiency, but vacuum heat collection pipe is in actual use, especially under light focusing thermal-arrest state, has the possibility of booster.More common reason has: 1, tend to cause booster because be heated inequality in the time of light focusing thermal-arrest state.2, since vacuum heat collection pipe when light focusing thermal-arrest state, temperature can reach more than 400 ℃ in the pipe, heat-conducting work medium in the vacuum heat collection pipe surpasses the generally thermal coefficient of expansion of the high-boron-silicon glass of employing of vacuum heat-collecting body institute, the excessive booster that causes of interior pressure because of himself thermal coefficient of expansion.
Booster especially is in the unexpected booster of vacuum heat collection pipe under the condition of high temperature in case generation may bring more serious consequence, can make that the high temperature refrigerant in the vacuum heat collection pipe splashes, and causes people and animals' injures and deaths or other device damage.The utility model purpose is exactly to propose a kind of new explosion-proof type vacuum heat collection pipe, the potential safety hazard that is proposed more than solving.
Summary of the invention:
The potential safety hazard that has booster at the traditional vacuum thermal-collecting tube, the utility model proposes a kind of explosion-proof type vacuum heat collection pipe, it is characterized in that working medium taking place at the rupture pressure disc of the attached one deck high transmission rate of outer wall card of the outer glass pipe of vacuum heat collection pipe when preventing the vacuum heat collection pipe booster splashes.
The technical scheme that its technical problem that solves the utility model adopts is: at the attached one deck rupture pressure disc of outer wall card of the outer glass pipe of traditional vacuum thermal-collecting tube, rupture pressure disc has stronger stretch-resistance and possesses high transmission rate, makes it be wrapped in the outer glass pipe outer wall of whole vacuum heat collection pipe.When the vacuum heat collection pipe booster, rupture pressure disc can reduce the possibility that working medium is splashed greatly.

The specific embodiment
As shown in Figure of description 2, outer wall card attached one deck rupture pressure disc (6) at the outer glass pipe (2) of vacuum heat collection pipe, when routine work, because of rupture pressure disc possesses high transmission rate, then do not influence the normal heat collection function of vacuum heat collection pipe, when the vacuum heat collection pipe booster took place, rupture pressure disc had stronger stretch-resistance, and rupture pressure disc can reduce the possibility that the vacuum heat-collecting intraductal working medium splashes greatly.
Claims (1)
- A kind of explosion-proof type vacuum heat collection pipe comprises vacuum heat collection pipe body, rupture pressure disc, it is characterized in that: working medium takes place at the rupture pressure disc of the attached one deck high transmission rate of outer wall card of the outer glass pipe of vacuum heat collection pipe when preventing the vacuum heat collection pipe booster and splash.
