Description
Technical field
The utility model relates to can cut down sealing-in 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 will provide to cut down sealing-in vacuum cycle heat collecting element solar collector.
The technical scheme in the invention for solving the technical problem: can cut down the vacuum cycle heat collecting element of sealing-in and load container and frame is installed forms one and can cut down sealing-in vacuum cycle heat collecting element solar collector with several.Load container comprises storage water heater boiler and heat collecting element connection collection box.The vacuum heat collection element that is connected with load container contains a Natural Circulation runner that is made of ascending tube, down pipe and release end of heat, the inner can of Natural Circulation runner but be not full of liquid heating agent, the ascending tube of the Natural Circulation runner absorber low thermal resistance interior with placing vacuum heat-insulating layer be connected or with the absorber integral production.Adopt one can cut down seal connector and be connected between the release end of heat of Natural Circulation runner and the cover glass tube.
Can also be in the heat collecting element vacuum heat-insulating layer setting and absorber or down pipe low thermal resistance be connected, have the bimetal leaf heating power element of free end pawl.
Can also make the ascending tube of heat collecting element Natural Circulation runner stretch into tubulose release end of heat inside.
Can also coat infrared reflective material at the non-light area of cover glass tube inner surface.
Can also on load container, be provided with the release end of heat of heat collecting element indent and cooperate the plug shape heat exchange interface of conducting heat and being connected.
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 one can cut down sealing-in vacuum cycle heat collecting element solar collector configuration diagram.
Fig. 2 is that an overtemperature protection can be cut down sealing-in vacuum cycle heat collecting element solar collector configuration diagram.
1. heat collecting elements among the figure; 2. load container; 3. ascending tube; 4. down pipe; 5. release end of heat; 6. vacuum heat-insulating layer; 7. absorber; 8. can cut down seal connector; 9. cover glass tube; 10. free end pawl; 11. heating power element.
The specific embodiment
Among Fig. 1, the vacuum cycle heat collecting element 1 that can cut down sealing-in inserts the load container 2 of band heat insulation layer, forms one and can cut down sealing-in vacuum cycle heat collecting element solar collector.The heat collecting element 1 that is connected with load container contains one and constitutes a Natural Circulation runner by ascending tube 3, down pipe 4 and tubulose release end of heat 5, the ascending tube 3 of Natural Circulation runner and absorber 7 integral productions that place in the vacuum heat-insulating layer 6 adopt one can cut down seal connector 8 the tubulose release end of heat 5 and the cover glass tube 9 of Natural Circulation runner is tightly connected.Can cut down material can either with metal solder, can be connected with the glass heat press seal again.
Among Fig. 1, adopt ascending tube 3 to stretch into the design of tubulose release end of heat 5 inside, help to improve collecting efficiency.
Vacuum heat-insulation between the ascending tube 3 of Fig. 1 embodiment and the down pipe 4, very favourable to the circulation thermal-arrest.
Fig. 1 embodiment can cut down sealing-in vacuum cycle heat collecting element solar collector and do the inclination installation that release end of heat 5 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 9 and be converted to heat energy on absorber 7, heat energy in absorber 7 is passed to ascending tube 3 heating agent and make the heating agent expanded by heating by ascending tube 3 come-up, tubulose release end of heat 5 places at the Natural Circulation runner, heating agent is emitted the heat energy temperature and is reduced entering down pipe 4, sinks to enter ascending tube 3 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.
The release end of heat 5 of Fig. 1 embodiment is that tubulose is outwardly directed.Vacuum cycle heat collecting element 1 also can adopt the heat release interface of indent.And setting cooperates the plug shape heat exchange interface of conducting heat and being connected with the release end of heat of heat collecting element indent on load container 2.
Inner surface coats infrared reflective material such as aluminium film in the non-light area of cover glass tube, can effectively reduce the radiation heat loss of heat collecting element.
Among Fig. 2, the vacuum cycle heat collecting element 1 that can cut down sealing-in with automatic overtemperature protection inserts the load container 2 of being with heat insulation layer, forms an automatic overtemperature protection and can cut down sealing-in vacuum cycle heat collecting element solar collector.Vacuum cycle heat collecting element 1 contains a Natural Circulation runner that is made of ascending tube 3, down pipe 4 and tubulose release end of heat 5; Ascending tube 3 and absorber 7 integral productions that place in the vacuum heat-insulating layer 6; The bimetal leaf heating power element 11 that is connected, has free end pawl 10 with down pipe 4 low thermal resistances is set in vacuum heat-insulating layer 6; Adopt one can cut down seal connector 8 the tubulose release end of heat 5 of Natural Circulation runner is tightly connected with cover glass tube 9.
Under the normal working temperature, by 3 heat releases of tubulose release end of heat.A plurality of free end pawls 10 of bimetal leaf heating power element 11 do not contact with cover glass tube 9.
When the empty solarization of heat collecting element internal temperature is too high; a plurality of free end pawls 10 of bimetal leaf heating power element 11 are heated to turn up and contact with cover glass tube 9 to position shown in the dotted line; partial heat energy is dispersed into environment by these free end pawls 10 and cover glass tube 9, makes the temperature of heat collecting element 1 reduce the realization overtemperature protection.Overtemperature protection can automatically terminate later.
Heating power element 11 also can be connected with absorber 7 low thermal resistances; Also can adopt memorial alloy to make the heating power element.
