Two embodiments are given as shown in the accompanying drawing.
Description
Technical field
The utility model relates to cover glass tube heat release vacuum cycle heat collecting element solar collector.
Background technology
Vacuum intubate solar water heater can provide the domestic hot-water in the winter time, but thermal-collecting tube internal memory hydro-thermal is heavy big, hot less, frost resistance is poor, can bombing, the single tube breakage can metal run out, the water-quality deterioration bacterium exceeds standard.Adopt the heat collector tube element can make anhydrous water heater in the pipe, but copper---hydro-thermal pipe cost height, the tangible performance degradation phenomenon of also existence freezing, that have easily.
Summary of the invention
The purpose of this utility model is that cover glass tube heat release vacuum cycle heat collecting element solar collector will be provided.
The technical scheme in the invention for solving the technical problem: with vacuum cycle heat collecting element and load container and cover glass tube heat release vacuum cycle heat collecting element solar collector of installation frame composition of several cover glass tube heat releases.The vacuum cycle heat collecting element by the cover glass tube of a closure, place absorber and a Natural Circulation runner that constitutes by ascending tube, down pipe and release end of heat in the cover glass tube to form, the inner can of Natural Circulation runner but be not full of liquid heating agent, the ascending tube of Natural Circulation runner with place absorber low thermal resistance in the vacuum heat-insulating layer to be connected or with the absorber integral production, contain an elasticity heat transfer piece between the release end of heat of Natural Circulation runner and the cover glass tube.
The beneficial effects of the utility model comprise: for the occasion of tiltable or positioned vertical, circulation conduct heat need not to be equipped with power, starts fast, freeze proof, pipe explosion, single tube damages still can thermal-arrest, can make water quality meet sanitary standard, hot many, solar collector that heat-insulating property is excellent; But heat exchange interface designs freedom, can prevent empty solarization accident to the insensitive semipermanent steady operation of vacuum at the heat collecting element of 20～500 ℃ of scopes, available mild steel and aluminium substitution copper, overtemperature protection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cover glass tube heat release vacuum cycle heat collecting element solar collector configuration diagram.
Fig. 2 is an overtemperature protection cover glass tube heat release vacuum cycle heat collecting element solar collector configuration diagram.
1. heat collecting elements among the figure; 2. load container; 3. cover glass tube; 4. absorber; 5. ascending tube; 6. down pipe; 7. release end of heat; 8. vacuum heat-insulating layer; 9. necking segment; 10. free end pawl; 11. heating power element.
The specific embodiment
Among Fig. 1, the vacuum cycle heat collecting element 1 of cover glass tube heat release inserts the load container 2 of band heat insulation layer, forms a cover glass tube heat release vacuum cycle heat collecting element solar collector.Load container 2 comprises water storage tank and connection collection box.Vacuum cycle heat collecting element 1 by the cover glass tube 3 of a closure, place absorber 4 and Natural Circulation runners that constitute by ascending tube 5, down pipe 6 and release end of heat 7 in the cover glass tube 3 to form, the ascending tube 5 of Natural Circulation runner and absorber 4 integral productions that place in the vacuum heat-insulating layer 8 adopt an elasticity heat transfer piece to conduct heat between the necking segment 9 of tubulose release end of heat 7 and cover glass tube 3.Tubulose release end of heat 7 is by elasticity heat transfer piece and necking segment 9 and load container 2 heat exchange.
The vacuum cycle heat collecting element solar collector of Fig. 1 embodiment cover glass tube heat release is done the inclination installation that release end of heat 7 height are put in the sun, and the heating agent liquid level shown in the oblique dotted line is the level of state.Sunlight sees through cover glass tube 3 and be converted to heat energy on absorber 4, heat energy in absorber 4 is passed to ascending tube 5 heating agent and make the heating agent expanded by heating by ascending tube 5 come-up, tubulose release end of heat 7 places at the Natural Circulation runner, heating agent is emitted the heat energy temperature and is reduced entering down pipe 6, sinks to enter ascending tube 5 behind the end once more and be heated and float.So along the circulation thermal-arrest that goes round and begins again of approach shown in the band arrow curve.Meanwhile, water or the heating agent in the load container 2 constantly heated.
Can omit by cover glass tube and necking segment thereof and load heat exchange and can cut down seal connector, good airproof performance, corrosion-resistant.
Sometimes, the load container that cooperates with heat collecting element also needs heat collecting element that such necking segment is arranged.
Vacuum heat-insulation between the ascending tube 5 of Fig. 1 embodiment and the down pipe 6, very favourable to the circulation thermal-arrest.
Inner surface coats infrared reflective material in the non-light area of cover glass tube, can effectively reduce the radiation heat loss of heat collecting element.
Among Fig. 2, insert the load container 2 of band heat insulation layer, form an automatic overtemperature protection cover glass tube heat release vacuum cycle heat collecting element solar collector with the cover glass tube heat release vacuum cycle heat collecting element 1 of automatic overtemperature protection.Vacuum cycle heat collecting element 1 by the cover glass tube 3 of a closure, place absorber 4 and Natural Circulation runners that constitute by ascending tube 5, down pipe 6 and release end of heat 7 in the cover glass tube 3 to form, absorber 4 integral productions that the ascending tube 3 of Natural Circulation runner is interior with placing vacuum heat-insulating layer 8; The bimetal leaf heating power element 11 that is connected, has free end pawl 10 with down pipe 6 low thermal resistances is set in vacuum heat-insulating layer 8; Adopt an elasticity heat transfer piece to conduct heat between tubulose release end of heat 7 and cover glass tube 3 necking segment 9.Tubulose release end of heat 7 is by elasticity heat transfer piece and necking segment 9 and load container 2 heat exchange.
Under the normal working temperature, tubulose release end of heat 7 is by elasticity heat transfer piece and 9 heat releases of cover glass tube 3 necking segment.The free end pawl 10 of bimetal leaf heating power element 11 does not contact with cover glass tube 3.
When the empty solarization of heat collecting element internal temperature is too high; the free end pawl 10 of bimetal leaf heating power element 11 is heated to turn up and contacts with cover glass tube 3 to position shown in the dotted line; partial heat energy is dispersed into environment by these free end pawls 10 and cover glass tube 3, makes the temperature of heat collecting element 1 reduce the realization overtemperature protection.Overtemperature protection can automatically terminate.
