Abstract
The invention discloses a solar collector tube, comprising an internal light absorption tube and an external light penetration tube; wherein, the internal light absorption tube is sheathed in the external light penetration tube and a vacuum layer is arranged between the internal light absorption tube and the external light penetration tube. The invention is characterized in that the internal and external surfaces of the internal light absorption tube wall are provided with a plurality of round salients; the number of the round salients on the internal surface are equal to that of the round salients on the external surface, and the round salients on the internal surface are over against the round salients on the external surface; each internal salient and each external salient just form a convex lens with focus on the center line of the internal light absorption tube. The internal light absorption tube adopts the convex lens condensation principle and the solar collector tube has better light absorption effect.
Description
Technical field
The present invention relates to a kind of solar energy heat collection pipe, especially a kind of interior extinction pipe has adopted the solar energy heat collection pipe of convex lens optically focused principle.
Background technology
At present, the solar energy heat collection pipe of prior art mostly is the glass tube of inside and outside light face.Adopt the solar water heater of such solar energy heat collection pipe, the thermal efficiency is low, can not use basically when sunlight is not too sufficient, especially the north of china in winter sunshine-duration is short, illumination is low, and the thermal conversion rate of illumination also obviously reduces, so that solar water heater can not normally use.More advanced is that open day is on July 7th, 1993, publication number is CN91111709.1, denomination of invention is the Chinese invention patent of efficient wave-type vacuum solar heat-collecting pipe, the outer surface of the inner tube of its disclosed solar energy heat collection pipe is corrugated, its objective is the extinction surface area that enlarges inner tube.May play a role according to its principle, but effect is not necessarily very desirable.So, design the solar energy heat collection pipe that a kind of better effects if, interior extinction pipe adopt convex lens optically focused principle, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides the solar energy heat collection pipe of a kind of better effects if, interior extinction pipe employing convex lens optically focused principle.
The technical scheme that the present invention solves its technical problem is:
A kind of solar energy heat collection pipe, form by interior extinction pipe and outer light-transmission tube, interior extinction pipe box is contained in the outer light-transmission tube, interior extinction pipe and outside vacuum layer is arranged between the light-transmission tube, it is characterized in that: in described, on the inside and outside surface of the tube wall of extinction pipe a plurality of circular protrusions are arranged, circular protrusions on the inner surface equates with circular protrusions quantity on the outer surface, and, circular protrusions on the inner surface and the circular protrusions on the outer surface over against, each internal projection and each outer lug just in time constitute convex lens, and the focus of each convex lens is all on the center line of interior extinction pipe.
The technical scheme that the present invention solves its technical problem can also be:
The extinction pipe can be the coloured glass with photo absorption performance in of the present invention, also can be the outer surface coating extinction film at interior extinction pipe.
The blind pipe or the straight pipe of the sealing of extinction Guan Weiyi end in of the present invention.
The section of solar energy heat collection pipe of the present invention is circular or fan-shaped.
The invention has the beneficial effects as follows:
Interior extinction pipe adopts convex lens optically focused principle, in relative unit are with in the time, the extinction better effects if, improve the operating efficiency of solar water heater, satisfy northern area bathing in winter, the requirement of southern desalinization, in the winter time even sunlight not overabundant the time, also can use solar energy, remedied the deficiency that solar water heater must could use under high light.
