Abstract
The utility model discloses a medium-high temperature solar evacuated collector tube used for a slot type heat collecting system. An existing medium-high temperature evacuated collector tube is improved, and a reflection plate A and a reflection plate B are arranged in a vacuum interlayer. The reflection plate A and the reflection plate B are both arranged in the axial direction of a glass outer tube and are located on two sides of a metal inner tube respectively; the fixed edge of the reflection plate A and the fixed edge of the reflection plate B are fixedly connected with the inner wall of the glass outer tube. The reflecting surface of the reflection plate A and the reflecting surface of the reflection plate B face towards the reflecting surface of a reflective mirror in the slot type heat collecting system, reflected light deviated from a selective absorbing coating of the outer surface of the metal inner tube is reflected by the reflective mirror to the reflecting surface of the reflection plate A and the reflecting surface of the reflection plate B, and after secondary reflection is carried out on the deviated reflected light by the reflection plate A and the reflection plate B, the reflected light is reflected to the selective absorbing coating of the outer wall of the metal inner tube. The medium-high temperature solar evacuated collector tube used for the slot type heat collecting system effectively improves working efficiency.
Description
Technical field
The utility model relates to a kind of heat collector, specifically, is a kind of middle high temperature solar vacuum heat collection pipe for the slot type collecting system.
Background technology
High temperature solar vacuum heat collection pipe in existing, as shown in Figure 1, have metal inner pipe 1 and glass outer tube 2, and metal inner pipe 1 coaxially is placed in glass outer tube 2, sealed at both ends, the middle vacuum interlayer 3 that forms; Glass outer tube 2 inside and outside walls are coated with ARC, and more sunshine is projected on the coating for selective absorption on metal inner pipe 1 outer surface, absorb more photo-thermal, improve the operating efficiency of thermal-collecting tube.
Middle high temperature solar vacuum heat collection pipe, be widely used in the groove type solar system; In the groove type solar system, sunshine is theoretical for directional light irradiates, and parallel radiation is to reflective mirror 4; Speculum 4 is parabolic shape, and the focus place that the sunshine of parallel radiation can be reflexed to reflective mirror 4 by reflective mirror 4 focuses on; Now, if, when all reverberation all reflexes on the coating for selective absorption of metal inner pipe 1 outer surface, sunshine can be reflexed to greatest extent to metal inner pipe 1 surface.But because there is the mismachining tolerance of alignment error and parts in the groove type solar system, so in the groove type solar system works, what be difficult to avoid orders about directional light after reflective mirror 4 reflections, the reverberation of speculum 4 edges departs from the coating for selective absorption of metal inner pipe 1 outer surface, as shown in Figure 2, reduce thus the operating efficiency of middle high temperature solar vacuum heat collection pipe, reduced the operating efficiency of whole groove type solar system simultaneously.
Summary of the invention
In order to address the above problem, the utility model improves high-temperature vacuum heat-collecting tube in existing, is provided with reflecting plate A and reflecting plate B in vacuum interlayer.Reflecting plate A and reflecting plate B, all along the glass outer axial tube to setting, lay respectively at the both sides of metal inner pipe; Reflecting plate A all is fixedly connected with the glass outer tube wall with the fixed edge of reflecting plate B.The reflective mirror reflecting surface of the reflecting surface of reflecting plate A and reflecting plate B in the slot type collecting system, the reverberation that departs from metal inner pipe outer surface coating for selective absorption that speculum is penetrated is mapped on the reflecting surface of reflecting plate A and reflecting plate B, after by reflecting plate A and reflecting plate B, the reverberation departed from being carried out to secondary reflection, be mapped on the coating for selective absorption of metal inner pipe outer wall.
The utility model has the advantage of:
1, the utility model thermal-collecting tube, effectively improved the middle high temperature solar vacuum heat collection pipe operating efficiency in the slot type collecting system, improved the operating efficiency of whole groove type solar system simultaneously;
2, the utility model thermal-collecting tube, facilitate the installation of groove type solar system and the manufacture of auxiliary component.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is for the middle high temperature solar vacuum heat collection pipe of slot type collecting system, high-temperature vacuum heat-collecting tube in existing is improved, as shown in Figure 3, be specially: in the vacuum interlayer 3 in middle high-temperature vacuum heat-collecting tube, be provided with reflecting plate A5 and reflecting plate B6, as shown in Figure 1; Reflecting plate A5 and reflecting plate B6 all axially arrange along glass outer tube 2, and length equates with glass outer tube 2, lays respectively at the both sides of metal inner pipe 1, and are positioned at the cross section homonymy of glass outer tube 2 axis.Reflecting plate A all is fixedly connected with glass outer tube 2 inwalls with the fixed edge of reflecting plate B, realizes reflecting plate A5 and the reflecting plate B6 location in 3 layers of vacuum clips.Reflecting plate A5 and reflecting plate B6 all tilt towards metal inner pipe 1, towards the side of metal inner pipe 1, are reflecting surface, by reflecting material, are made.Reflecting plate A5 and reflecting plate B6 be the selective absorption film on contacting metal inner tube 1 outer wall not.
As shown in Figure 4, the middle high-temperature heat-collection pipe of said structure is applied in the slot type collecting system, make the reflecting surface of reflecting plate A5 and reflecting plate B6 towards speculum 4, the reverberation that departs from metal inner pipe 1 outer surface coating for selective absorption that makes thus speculum 4 penetrate is mapped on the reflecting surface of reflecting plate A5 and reflecting plate B6, after by reflecting plate A5 and reflecting plate B6, the reverberation departed from being carried out to secondary reflection, finally be mapped on the coating for selective absorption of metal inner pipe 1 outer wall, and reflecting plate A5 and reflecting plate B6 can not affect the positive direct projection of sunshine.
The width of said reflection plate A5, reflecting plate B6, fixed position between the fixed edge of reflecting plate A5, reflecting plate B6 and glass outer tube, and the angle of inclination of reflecting plate A5 and reflecting plate B6, all according to focusing on the position specific design of focus in the size of reflective mirror 4 in the slot type collecting system and slot type collecting system.
