Abstract
The utility model relates to an internal light focusing solar energy collecting tube. The inner surface of the glass tube of the heat collecting tube is provided with solar reflection concentrating thin film and the metal heat-absorbing body of the heat collecting tube is provided with heat-absorbing fins coated with a heat-absorbing film; consequently, without tracking the sun by the heat collecting tube, the heat collecting tube can congregate the solar radiation from different directions and transform the solar radiation to heat energy in maximum. The internal light focusing solar energy collecting tube of the utility model with unique conception, scientific design, high thermal efficiency, good performance and precise making can be widely used in various fields of solar heating, refrigerating, sea water desalting and industry heating. This technique does predominant contribution to China fully utilizing the solar energy resource.
Description
Technical field:
The utility model relates to the solar energy heating Manifold technology.
Background technology:
Existing solar vacuum heat-collecting pipe, absorber normally is installed in glass tube, because the absorber of this thermal-collecting tube only can absorb solar radiation over against the part of the sun, the heat absorption capacity of other parts is very little, thereby the running temperature of thermal-collecting tube is not very high, and the thermal efficiency is affected.Although some thermal-collecting tube can use outer concentrator,, generally do not adopt because of reasons such as cost height.
Summary of the invention
The purpose of this utility model just provides a kind of interior concentrating solar thermal-collecting tube, and it has solved above-mentioned technical problem with the more design of science, and its production cost and the ratio of performance to price are better than the existing heat collector that adds solar panel in glass tube.
The utility model is achieved in that on the inner surface of the glass tube of thermal-collecting tube (heat pipe-type and direct current tubular type), is provided with arc surfaced reflecting condensation film.Metal absorber surface at thermal-collecting tube has absorbing film.On the metal absorber surface of thermal-collecting tube, the heat absorption fin with absorbing film is set.
Concentrating solar thermal-collecting tube in the utility model, design is unique, design science.Because glass tube inner surface at thermal-collecting tube, be provided with the arc surfaced reflecting condensation film of the relative absorber back side and side, make thermal-collecting tube under the situation of not following the tracks of the sun, assemble solar radiation, therefore can to greatest extent solar radiation be changed into heat energy from different directions.Add that heat absorption fin and absorbing film thereof to the reinforcement of thermal-collecting tube heat absorption function, can be increased to more than 200 ℃ the operating temperature of thermal-collecting tube, the scope of application significantly improves.The utility model function admirable is made exquisiteness, can be widely used in solar energy heating, refrigeration, and fields such as desalinization and industry heating, this technology will be utilized solar energy resources more fully for China, make remarkable contribution.
