Abstract
The invention provides a vacuum circulating heat-collecting component adopting a cover glass tube for heat release. The component comprises a closed cover glass tube, an absorber arranged in the cover glass tube and a natural circulating channel formed by an ascending tube, a descending tube and a heat release end. The invention is characterized in that the ascending tube of the natural circulating channel is connected with the absorber arranged in a vacuum heat insulation layer under low heat resistance or and the absorber as a whole are manufactured; and an elastic heat transfer part is arranged between the heat release end and the cover glass tube. The invention has the following beneficial effects: in the places where a collector can be obliquely or vertically mounted, the vacuum circulating heat-collecting component dispenses with power for circulating heat transfer, is started quickly, resists frost, is free from tube explosion, can still collect heat even if a single tube is damaged, and can be used for manufacturing a solar heat collector which can produce water with quality in line with the hygienic standard, can gain more heat and has excellent heat insulation property; and a heat exchange interface is freely designed, the heat-collecting component is insensitive to the vacuum degree, can semi-permanently and stably work at the temperature of 20-500 DEG C and can use low-carbon steel and aluminium to replace copper, and the heat-collecting component with a function of overheat protection can prevent a stagnation accident. Two embodiments are given in the invention in combination with the drawings.
Description
Technical field
The present invention relates to the vacuum cycle heat collecting element of cover glass tube heat release.
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 objective of the invention is to provide the vacuum cycle heat collecting element of cover glass tube heat release.
The present invention solves the technical scheme that its technical problem is taked: with the cover glass tube of a closure, the vacuum cycle heat collecting element that places absorber in the cover glass tube and Natural Circulation runner that is made of ascending tube, down pipe and release end of heat to form a cover glass tube heat release.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.
Beneficial effect of the present invention comprises: 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a cover glass tube heat release vacuum cycle heat collecting element configuration diagram.
Fig. 2 is an overtemperature protection cover glass tube heat release vacuum cycle heat collecting element configuration diagram.
1. cover glass tubes among the figure; 2. absorber; 3. ascending tube; 4. down pipe; 5. release end of heat; 6. vacuum heat-insulating layer; 7. necking segment; 8. free end pawl; 9. heating power element.
The specific embodiment
Among Fig. 1, adopt a closure cover glass tube 1, place absorber 2 and a Natural Circulation runner that constitutes by ascending tube 3, down pipe 4 and release end of heat 5 in the cover glass tube 1 to form a cover glass tube heat release vacuum cycle heat collecting element.The ascending tube 3 of Natural Circulation runner and absorber 2 integral productions that place in the vacuum heat-insulating layer 6.Be lined with an elasticity heat transfer piece between the tubulose release end of heat 5 of Natural Circulation runner and cover glass tube 1 necking segment 7 and conduct heat to improve, tubulose release end of heat 5 is by elasticity heat transfer piece and necking segment 7 heat releases.
The vacuum cycle heat collecting element of Fig. 1 embodiment cover glass tube heat release is done 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 1 and be converted to heat energy on absorber 2, heat energy in absorber 2 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.
Answer degasification before the Natural Circulation runner can heating agent, can finishes and should seal.The design of Natural Circulation runner and the selection of heating agent and can amount thereof should satisfy: the 1) foundation of Natural Circulation; 2) the heating agent stable performance be not easy thermal decomposition, saturated vapor force down, not with Natural Circulation runner generation chemical reaction; 3) possessing the heating agent expansion space in the Natural Circulation runner solidifies heating agent or empty relevant parts is not produced adverse effect when shining volumetric expansion; 4) the release end of heat operating mode is good.
Natural Circulation runner of the present invention can also be made with glass.
Can omit by cover glass tube and necking segment heat release thereof 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.
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; constitute a Natural Circulation runner with ascending tube 3, down pipe 4 and tubulose release end of heat 5; the ascending tube 3 of Natural Circulation runner and absorber 2 integral productions that place in the vacuum heat-insulating layer 6; the bimetal leaf heating power element 9 that is connected, has free end pawl 8 with down pipe 4 low thermal resistances is set in vacuum heat-insulating layer 6, forms an overtemperature protection cover glass tube heat release vacuum cycle heat collecting element.
Under the normal working temperature, tubulose release end of heat 5 is by elasticity heat transfer piece and 7 heat releases of cover glass tube 1 necking segment.The free end pawl 8 of bimetal leaf heating power element 9 does not contact with cover glass tube 1.
When the empty solarization of heat collecting element internal temperature is too high; the free end pawl 8 of bimetal leaf heating power element 9 is heated to turn up and contacts with cover glass tube 1 to position shown in the dotted line; partial heat energy is dispersed into environment by these free end pawls 8 and cover glass tube 1, makes the temperature of heat collecting element reduce the realization overtemperature protection.Overtemperature protection can automatically terminate later.
