Abstract
What the utility model belonged to solar heat utilizes field, specifically a kind of solar energy glass vacuum endothermic tube, comprise the two-layer inner casing type glass tube be made up of with the outer layer glass tube being enclosed within its outside inner layer glass tube, space between the outer wall of inner layer glass tube and the inwall of outer layer glass tube forms vacuum chamber, the outer surface of inner layer glass tube is coarse concavo-convex peak valley hair side, and coarse concavo-convex peak valley hair side is provided with heat absorption rete.Because the concavo-convex peak valley of glass tube exterior surface is uneven, light vertical irradiation face is increased, and the light repeatedly reflected in peak valley face increases, and peak valley surface linear increases, and light-receiving area strengthens, and the heat absorption rete adding upper surface is dull surface, light absorptive great change.Utility model people draws in scientific algorithm and field experiment, solar energy glass vacuum endothermic tube of the present utility model, improves 30%-50%, in specific environment, reach about 70% than the existing solar vacuum glass heat absorbing pipe thermal efficiency.
Description
Technical field
What the utility model related to solar heat utilizes field, and specifically a kind of inner layer glass tube is coarse hair side and solar energy glass vacuum endothermic tube with sub-light heat absorption rete.
Background technology
Traditional solar energy glass vacuum endothermic tube, shown in Fig. 1-3, be made up of pipe in printing opacity outer tube and antisolar glass, in antisolar glass, the outer surface of pipe has the heat absorption rete of high-absorbility, is evacuated between interlayer.Heat absorption rete be on bright and clean silicon boron glass pipe by Vacuum Magnetic sputtering technology, utilize the metal light rete of light palladium material sputtering sedimentation.As bright as a sixpence glass inner tube is as same " glittering metal bar ", under the condition of illumination, because body is a cylinder, sensitive surface is again a bright hemisphere, and on body surface, the round-the-clock vertical irradiation of sunlight only has a point, and even a line, all the other light increase by incidence angle, and oblique ray becomes many, therefore absorptance and photothermal deformation rate very low (generally only having 50% in industry).
Utility model content
The technical problems to be solved in the utility model is to provide a kind of inner layer glass tube and is coarse hair side and the solar energy glass vacuum endothermic tube of the rete that absorbs heat with sub-light, to improve the thermal absorptivity of solar energy glass vacuum pipe in unit are, save the means of production, strengthen the utilization of sunlight resource, expand the application that solar energy optical-thermal is lived work, agricultural production and the people.
In order to solve the problem, the utility model is achieved through the following technical solutions:
A kind of solar energy glass vacuum endothermic tube, comprise the two-layer inner casing type glass tube be made up of with the outer layer glass tube being enclosed within its outside inner layer glass tube, space between the outer wall of inner layer glass tube and the inwall of outer layer glass tube forms vacuum chamber, the outer surface of described inner layer glass tube is coarse concavo-convex peak valley hair side, and described coarse concavo-convex peak valley hair side is provided with heat absorption rete.
Further, described heat absorption rete is sub-light heat absorption rete.
Further, described sub-light heat absorption rete selects sub-light palladium material to form by magnetron sputtering is long-pending.
Further, the surface roughness of described coarse concavo-convex peak valley hair side is 0.08-0.5mm.
Further, outer layer glass tube is the low iron transparent glass tube of silicon boron printing opacity.
Compared with prior art, the beneficial effects of the utility model are: the outer surface of the utility model inner layer glass tube is coarse concavo-convex peak valley hair side, coarse concavo-convex peak valley hair side is provided with sub-light heat absorption rete, because the concavo-convex peak valley of glass tube exterior surface is uneven, light vertical irradiation face is increased, and the light repeatedly reflected in peak valley face increases, peak valley surface linear increases, light-receiving area strengthens, and the heat absorption rete adding upper surface is dull surface, light absorptive great change.Utility model people draws in scientific algorithm and field experiment, solar energy glass vacuum endothermic tube of the present utility model, improves 30%-50%, in specific environment, reach about 70% than the existing solar vacuum glass heat absorbing pipe thermal efficiency.
Vacuum glass heat absorbing pipe direct projection area of the present utility model is large, repeatedly reflect wide, sensitive surface is many again, the huge increasing of overall sensitive surface, the sub-light heat absorption rete reflecting rate simultaneously adopted is low, therefore this glass evacuated endothermic tube thermal efficiency is high, under equivalent environment operating mode, it is 1.3 ~ 1.5 times of traditional product thermal conversion rate, not only save material in solar thermal utilization industry, expand and utilize field, and more reduce erection space and space, be the revolution again of solar energy optical-thermal vacuum tube, major step can be strided forward for China's industrialization solar thermal utilization.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 4-7, a kind of solar energy glass vacuum endothermic tube, comprise the two-layer inner casing type glass tube be made up of with the outer layer glass tube 2 being enclosed within its outside inner layer glass tube 1, space between the outer wall of inner layer glass tube and the inwall of outer layer glass tube forms vacuum chamber, outer layer glass tube is the low iron transparent glass tube of silicon boron printing opacity, the outer surface of inner layer glass tube is coarse concavo-convex peak valley hair side 3, the surface roughness of peak valley hair side can be 0.08mm, 0.09mm, 0.1mm, 0.3 or 0.5mm, coarse concavo-convex peak valley hair side is provided with sub-light heat absorption rete 4, sub-light heat absorption rete 4 selects sub-light palladium material to form by magnetron sputtering is long-pending.
Solar energy glass vacuum endothermic tube production technology of the present utility model is identical with traditional product technique, traditional process equipment is changed without the need to changing, only at the preposition surface processing device of streamline, make glass inner tube surface irregularity peak valley moderate, the degree of depth is advisable, guarantee that glass inner tube stress is up to standard, hair side is even.Put into plated film storehouse, select sub-light plated film palladium material, plate sub-light heat absorption rete by normal process, take out the inner layer glass tube plated, add cover silicon boron glass outer tube, place interior pipe holder 5, two hot melt sealing-in, draw tail, find time, air-breathing, the high solar energy glass vacuum endothermic tube of absorptivity rolls off the production line finished product, except roughness value is except control, technological process is carried on as usual, and changes without the need to expanding or reinvests.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
