Abstract
The utility model relates to a reflective light-gathering type solar vacuum tube, and is a vacuum tube with large outer diameter. The utility model is made by utilizing a principle that the reflection gathers lights and collects heat. The circumference diameter of an outer tube is large, one surface of the outer tube facing the sun is transparent arced glass, the other surface of the outer tube is shaped according to a curvilinear plane of a concave mirror, the inner wall of the outer tube does mirror surface process and thus the sunlight focusing mirror surface is formed. An inner tube forms a hollow cylinder shape, and one surface of the inner tube facing the sun is plated with an absorbing layer. The vacuum between the inner tube and the outer tube is pumped. The sunlight entering the outer tube forms a focus line in the inner tube by a focusing function of the surface of the concave mirror, the water in the inner tube fast raises temperature, the heat collection effect is good and the water is boiled in four seasons. The utility model not only can be used for washing and bathing, but also can be used for cooking food and heating in winter.
Description
Affiliated technical field
The utility model belongs to a kind of big external diameter high temperature solar vacuum tube.
Background technology
Present solar energy vacuum tube is to be formed by concentric two circular glass pipes melting welding, vacuumizes between the inner and outer pipes, and outer wall of inner tube plating selectively absorbing layers forms thermal-collecting tube.The coating of thermal-collecting tube improves in any case, because its residing environment temperature is not high, so be difficult to water is heated to best regenerator temperature (100 degree).Therefore, present solar energy can only rest within the narrow and small range of application of scrubbing bathing.
Summary of the invention
In view of the deficiency of original vacuum tube, the utility model utilizes the reflecting condensation effect of concave mirror, and the suffered ray density of thermal-collecting tube is increased, and environment temperature raises, thereby improves collecting efficiency, makes water reach boiling, the ideal temperature of drinking.
Technical solution of the present utility model is: reflecting condensation formula solar energy vacuum tube comprises glass outer tube and glass inner tube (thermal-collecting tube) two parts composition.The week footpath of outer tube is big, belongs to non-circular cross sections, and one side is transparent semicircle on the sunny side; Another side is by the moulding of concave mirror curvilinear plane, and inwall is done mirror process (silver-plated) and become the reflecting layer.Interior pipe (thermal-collecting tube) belongs to the circular glass pipe, and diameter is little, the one side plating selectively absorbing layers that faces south, and another side is transparent vitreum.The center line of interior pipe overlaps with the focal line of concave mirror curvilinear plane.Vacuumize between interior pipe and the outer tube.(interior pipe can use the collector metal pipe).
The utility model is because the outer tube of vacuum tube is provided with concave mirror camber reflection layer, the solar radiation that enters outer tube is to the reflecting layer, owing in the pipe, form focal line and directly heat conducted to the water in the interior pipe (or superconducting fluid) in the focussing force of concave mirror, sunlight can reflex to regularly.Direct projection is absorbed by the absorption layer to the sunlight on the outer wall of inner tube.Thereby tens times of ground of the environment temperature of interior pipe increase.Specular layer is in that dust stratification dirt is not out of shape in the vacuum.In pipe two perforate also stretch out outer tube, be convenient to install and use convection current with water.
The beneficial effects of the utility model are: this vacuum tube collecting efficiency height, interior environment temperature height.Not only the basic problem that bathing is scrubbed can be solved, and the problem of drinking water and food boiling can be solved.The use of can also connecting with indoor water temperature air-conditioning or heating installation is used for warming.

The specific embodiment
Reflecting condensation formula solar energy vacuum tube is made up of the two large divisions: thermal-collecting tube (1), glass outer tube (2).Glass outer tube (2) is made up of first half (3) and latter half (4); First half (3) belongs to the circular arc clear glass; Latter half (4) is pressed the concave mirror curved surface forming, and inwall is made mirror process, forms mirror process layer (5).Thermal-collecting tube (1) belongs to the circular glass pipe, and a side is coated with thermal-arrest absorbed layer (6) on the sunny side, and opposite side is a clear glass.The center line of thermal-collecting tube (1) overlaps with the optically focused focal line of outer tube latter half (4), vacuumizes between thermal-collecting tube (1) and the glass outer tube (2), and thermal-collecting tube (1) and glass outer tube (2) melting welding are integral.Thermal-collecting tube (1) both ends open, and lean out from the two ends of glass outer tube (2) is convenient to install and use the convection current with internal liquid.(operation principle is seen Fig. 3).
Claims (3)
1. reflecting condensation formula solar energy vacuum tube is made up of glass outer tube and glass inner tube, it is characterized in that: interior pipe (thermal-collecting tube) is a hollow cylinder, and diameter is smaller, and one side is coated with selectively absorbing layers on the sunny side, and thermal-arrest is used; Outer tube is the non-circular cross sections hollow glass tube, and Zhou Jing is bigger, and one side is transparent circular arc on the sunny side, and another side is pressed the moulding of concave mirror curvilinear plane, and inwall (silver-plated) is done mirror process and formed the optically focused reflecting layer, vacuumizes between interior pipe and the outer tube.
2. reflecting condensation formula solar energy vacuum tube according to claim 1 is characterized in that: the center line of interior pipe overlaps with the focal line of outer tube reflecting surface.
3. reflecting condensation formula solar energy vacuum tube according to claim 1 is characterized in that: the both ends open of interior pipe, and stretch out from the two ends of outer tube.
