Six embodiments are given through combining with the attached drawings.
Description
Technical field
The utility model relates to indent heat release interface 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 indent heat release interface vacuum cycle heat collecting element solar collector will be provided.
The technical scheme in the invention for solving the technical problem: with several indent heat release interface vacuum cycle heat collecting elements and load container and indent heat release interface vacuum cycle heat collecting element solar collector of installation frame composition.Load container comprises storage water heater boiler and heat collecting element connection collection box.With the indent heat release interface vacuum cycle heat collecting element absorber that places in the vacuum heat-insulating layer that load container is connected, a Natural Circulation runner that is made of ascending tube, down pipe and release end of heat, and the heat release interface of an indent is formed.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.The inner can of Natural Circulation runner but be not full of liquid heating agent.Here, release end of heat is relative circulatory flow; The heat release interface is relative heat collecting element, and both are meant same object sometimes.
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.

The specific embodiment
Among Fig. 1, embedded indent heat release interface vacuum cycle heat collecting element 1 cooperates to conduct heat with plug shape heat exchange interface 2 load containers and is connected, and forms an embedded indent heat release interface vacuum cycle heat collecting element solar collector.Plug shape heat exchange interface 2 can in a row be fixedly installed on the water storage tank or heat collecting element connection collection box that has heat insulation layer, also can adopt flexible pipe to be connected with another loop, water route.Cooperate the embedded indent heat release interface heat collecting element 1 that is connected that conducts heat to contain a Natural Circulation runner that constitutes by ascending tube 3, down pipe 4 and tubulose release end of heat 5 with plug shape heat exchange interface 2 load containers.The Natural Circulation runner embeds all-glass vacuum thermal-collecting tube, adopts thermofin 7 to conduct heat between its ascending tube 3 and the thermal-collecting tube inner glass tube 6.
Fig. 1 embodiment embedded vacuum cycle set thermal element solar collector 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 and be converted to heat energy on the absorbing film of thermal-collecting tube inner glass tube 6, heat energy is passed to the heating agent in the ascending tube 3 by inner glass tube 6 and thermofin 7 and is made the heating agent expanded by heating by ascending tube 3 come-ups, 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.
Indent heat release end face vacuum cycle heat collecting element solar collector adopts the less plug shape heat exchange interface of volume, saves material and good heat insulating; The plug shape heat exchange interface installation and maintenance of adopting flexible pipe to connect are more convenient.
For reducing the hot short circuit between upper and lower line pipe, embedded vacuum cycle set thermal element 1 can also adopt the down pipe that has heat insulation layer.
Among Fig. 2, the indent heat release end face vacuum cycle heat collecting element 1 of overtemperature protection cooperates to conduct heat with plug shape heat exchange interface 2 load containers and is connected, and forms an overtemperature protection indent heat release end face vacuum cycle heat collecting element solar collector.Heat collecting element 1 contains a Natural Circulation runner that is made of ascending tube 3, down pipe 4 and coil heat exchanger release end of heat 5, ascending tube 3 and absorber 9 integral productions that place in the vacuum heat-insulating layer 8.The bimetal leaf heating power element 11 that is connected, has free end pawl 10 with down pipe 2 low thermal resistances is set in heat collecting element 1 vacuum heat-insulating layer 6.Coil heat exchanger release end of heat 5 cooperates to conduct heat with cover glass tube 10 concave sections 11 and is connected.Be lined with an elasticity heat transfer piece between coil heat exchanger release end of heat 5 and cover glass tube 10 concave sections 11.
Under the normal working temperature, coil heat exchanger release end of heat 5 is by elasticity heat transfer piece and cover glass tube 10 concave sections, 11 heat releases.The free end pawl 12 of bimetal leaf heating power element 13 does not contact with cover glass tube 10.
When the empty solarization of heat collecting element internal temperature is too high; the free end pawl 12 of bimetal leaf heating power element 13 is heated to turn up and contacts with cover glass tube 10 to position shown in the dotted line; partial heat energy is dispersed into environment by these free end pawls 12 and cover glass tube 10, makes the temperature of heat collecting element 1 reduce the realization overtemperature protection.Overtemperature protection can automatically terminate later.
The coil heat exchanger release end of heat 5 that cooperates with cover glass tube 10 concave sections 11 among Fig. 2 embodiment can also adopt other forms, for example the jacketed type exchanger release end of heat that cooperates with cover glass tube 10 concave sections 11 arranged concentric.
Can omit by cover glass tube and load heat exchange and can cut down seal connector, good airproof performance, corrosion-resistant.
Vacuum heat-insulation between the ascending tube 3 of Fig. 2 embodiment and the down pipe 4, 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.
