The solar vacuum pipe of the utility model has the advantages of simple structure, better heat collection capability, better heating effect and better utilization ratio of sun light.
Description
Technical field
The utility model relates to a kind of vacuum tube, particularly relates to a kind of solar energy vacuum tube.
Background technology
At present because resource is relatively more nervous, so it is the project that various countries all relatively pay attention to that the utilization of solar energy resources just becomes, general small-sized solar heater uses all is to use solar energy vacuum tube mostly, such solar energy vacuum tube, all be to constitute by glass outer tube and glass inner tube, outer tube sleeve is located at outside the interior pipe, be tightly connected between the end face of outer tube and interior pipe, form confined space between outer tube and the interior pipe, be full of vacuum in the confined space, the media liquid of heating is housed in the interior pipe, generally is water, and outer wall of inner tube is coated with coating for selective absorption.Solar energy vacuum tube is that solar irradiation is incident upon on the outer tube, and the coating for selective absorption on the outer wall of inner tube is converted into heat energy with the radiation of sunshine, and the heat energy after the conversion heats the water in the interior pipe, and then reaches the purpose of utilizing solar energy heating water.
Summary of the invention
The utility model is finished in order to solve deficiency of the prior art, and the purpose of this utility model provides that a kind of simple in structure, heat build-up ability is better, heating better effects if, the better solar energy vacuum tube of sunlight utilization rate.
Solar energy vacuum tube of the present utility model, comprise glass outer tube and the glass inner tube that is sheathed on described outer tube inside, heating media liquid is housed in the pipe in described, described outer wall of inner tube is coated with coating for selective absorption, be tightly connected between the end face of described outer tube and interior pipe, form confined space between described outer tube and the described interior pipe, be full of vacuum in the described confined space, it is characterized in that: the vertical stationary arrangement of described outside pipe has convex lens, the focal length of described convex lens is greater than distance between described outer tube and the interior pipe, and described convex lens are gathered in the interior media liquid of the described interior pipe of described interior pipe external heat with sunshine.
Solar energy vacuum tube of the present utility model can also be:
Described convex lens are at least two.
Described convex lens are three, and described each convex lens are vertically arranged.
Described convex lens are at least five, and described each convex lens are vertically arranged.
Described outer tube is around self axis rotation, and described outer tube drives described convex lens group motion when rotating.
Described convex lens diameter is 1-5cm.
Solar energy vacuum tube of the present utility model, the advantage that has in terms of existing technologies is: the vertical stationary arrangement of outside pipe has convex lens, the focal length of convex lens is greater than distance between outer tube and the interior pipe, and convex lens are gathered in the media liquid in the pipe in the described interior pipe external heat with sunshine.Because interior pipe is positioned within one times of focal length of convex lens, the sunshine that makes convex lens will be radiated on the outer tube is further assembled on inner pipe, and it is more concentrated to make interior pipe go up the solar energy of assembling, and solar energy utilization rate is higher, the heating better effects if.

The specific embodiment
Fig. 1 to Fig. 3 is described in further detail the utility model below in conjunction with accompanying drawing.
Solar energy vacuum tube of the present utility model comprises glass outer tube 1 and the glass inner tube 2 that is sheathed on outer tube 1 inside, and heating media liquid is housed in the interior pipe 2, because the existing solar water heater that is generally that utilizes solar energy, so heating media liquid is generally water.Interior pipe 2 outer walls are coated with coating for selective absorption, are tightly connected between the end face of outer tube 1 and interior pipe 2, form confined space between outer tube 1 and the described interior pipe 2, are full of vacuum in the confined space, and such solar energy vacuum tube can absorb sunshine and be converted into heat energy.Outer tube 1 outside vertically stationary arrangement has convex lens 3, and the focal length of convex lens 3 is managed the media liquid in 2 greater than distance between described outer tube 1 and the interior pipe 2 in pipe 2 external heat in convex lens 3 are gathered in sunshine.Like this, because interior pipe 2 is positioned within 3 one times of focal lengths of convex lens, the sunshine that makes convex lens 3 will be radiated on the outer tube 1 further accumulates on the interior pipe 2, and the solar energy of gathering is more concentrated on the feasible interior pipe 2, and solar energy utilization rate is higher, the heating better effects if.Convex lens 3 are at least two, and concrete convex lens 3 are three, and each convex lens 3 is vertically to arrange.Also can be 3 five on convex lens, described each convex lens 3 be vertically arranged.The diameter of convex lens 3 can be 1-5cm, can certainly use larger sized convex lens.Such convex lens 3 can be arranged on outer tube 1 outer wall and to improve solar energy utilization rate and can guarantee to arrange convex lens 3 more than at least five again.
Solar energy vacuum tube of the present utility model, can also be that outer tube 1 can be around self axis rotation, driving described convex lens 3 when outer tube 1 rotation together rotates, specifically can be when winter, use spanner with outer tube 1 rotation, it is rotated along with the change of sun angle, and then drive convex lens 3 rotate to one side on the sunny side, improve the efficiency of heating surface and solar energy utilization rate, when summer, for the water in the pipe 2 in avoiding is heated too hotly, outer tube 1 can be rotated to the one side of the sun dorsad, can avoid the water temperature of the water in the pipe 2 in the solar energy vacuum tube too high like this.
Solar energy vacuum tube of the present utility model; can also there be at least two outer tubes 1 outer cover to be provided with the transparent vacuum protective cover; described protective cover top is provided with convex lens; because existing solar heater is made up of a plurality of solar energy vacuum tubes; in the winter of northern China cold; in order to prevent the solar energy vacuum tube bursting by freezing; also can be at the outside sheathed bigger transparent vacuum protective cover of all solar energy vacuum tubes; can also be at the external stability convex lens of vacuum protective cover; in the protection bursting by freezing, further assemble sunshine, improve the efficiency of heating surface and solar energy utilization ratio.Protective cover can be rotated by whole sun-tracing, makes convex lens keep always towards the sunlight face.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
