Abstract
The utility model provides a solar heat-collecting device with a vacuum circulating heat-collecting element sealed with a glass tube by fusing. The solar heat-collecting device consists of a vacuum circulating heat-collecting element sealed with a glass tube by a fusing way, a load container and an installation frame. The solar heat-collecting device is characterized in that the heat-collecting element consists of an absorbing body arranged in a vacuum heat-insulating layer, and a glass natural circulating runner which is made of glass and consists of an ascending pipe, a descending pipe and a heat discharging end; the ascending pipe is connected with the absorbing body by a low resistance; and a cover glass tube is fused with the heat discharging end of the glass tube. The utility model has the benefits that: for obliquely or vertically arranged occasions, the circulating heat transmission does not need powers, the solar heat-collecting device has quick starting process, resists frost, does not blast pipe, can collect heat even when a single tube is damaged, can manufacture the water with the quality meeting the sanitary standards, obtains excessive heat, and has excellent heat-preservation performance; and the solar heat-collecting device has free design on the heat exchanging interface and good glass fuse-sealing performance, is insensitive with vacuum degree, can work under the scope of 20 to 500 DEG C in a half-permanent stable manner, can replace copper with middle steel and aluminium, and can resist the corrosion by adopting the glass heat discharging end. One embodiment is provided in the attached figure.
Description
Technical field
The utility model relates to glass tube sealing by fusing 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 glass tube sealing by fusing vacuum cycle heat collecting element solar collector will be provided.
The technical scheme in the invention for solving the technical problem: with several glass tube sealing by fusing vacuum cycle heat collecting elements and load container and frame is installed forms a table glass pipe sealing by fusing vacuum cycle heat collecting element solar collector.Glass tube sealing by fusing vacuum cycle heat collecting element is made up of the glass Natural Circulation runner that places absorber in the vacuum heat-insulating layer and the ascending tube with the glass manufacturing, down pipe and a release end of heat to constitute, 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 is connected, and cover glass tube is connected with the glass tube release end of heat fusion of Natural Circulation runner.
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 design is free, corrosion-resistant at 20～500 ℃ of scopes, available mild steel and aluminium substitution copper, glass head seal good airproof performance, glass release end of heat to the insensitive semipermanent steady operation of vacuum.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a table glass pipe sealing by fusing vacuum cycle heat collecting element solar collector configuration diagram.
1. heat collecting elements among the figure; 2. load container; 3. vacuum heat-insulating layer; 4. absorber; 5. ascending tube; 6. down pipe; 7. release end of heat; 8. cover glass tube; 9. necking segment.
The specific embodiment
Among Fig. 1, use the vacuum cycle heat collecting element 1 of glass tube sealing by fusing to insert the load container 2 of being with heat insulation layer, form a table glass pipe sealing by fusing vacuum cycle heat collecting element solar collector.Load container 2 comprises water storage tank and connection collection box.Heat collecting element 1 is made up of the glass Natural Circulation runner that places absorber 4 in the vacuum heat-insulating layer 3 and the ascending tube 5 by the glass manufacturing, down pipe 6 and a release end of heat 7 to constitute, ascending tube 5 is connected with aluminium section bar absorber 4 low thermal resistances in placing vacuum heat-insulating layer 3, and cover glass tube 8 passes through a necking segment 9 and is connected with glass tube release end of heat 7 arranged concentric of Natural Circulation runner and with 7 fusions of glass tube release end of heat.
Fig. 1 embodiment glass tube sealing by fusing vacuum cycle heat collecting element solar collector 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 8 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.
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.
Claims (3)
1. glass tube sealing by fusing vacuum cycle heat collecting element solar collector, by several glass tube sealing by fusing vacuum cycle heat collecting elements and load container and frame is installed forms, glass tube sealing by fusing vacuum cycle heat collecting element is by absorber and an ascending tube of being made by glass of placing in the vacuum heat-insulating layer, the glass Natural Circulation runner that down pipe and release end of heat constitute is formed, the inner can of Natural Circulation runner but be not full of liquid heating agent, the ascending tube absorber low thermal resistance interior with placing vacuum heat-insulating layer that it is characterized in that the Natural Circulation runner is connected, and cover glass tube is connected with the glass tube release end of heat fusion of Natural Circulation runner.
