Embodiment 1

[0021] Example 1: Please refer to Figure 1-4 , a kind of all-glass double-vacuum heat-gathering and radiation solar collector tube, comprising an outer cover glass tube 1, an inner glass tube 2 and a core tube 3, the outer cover glass tube 1 is provided with a support member 7, and the outer cover glass tube 1 The support member 7 is provided with an inner glass tube 2, and the inner glass tube 2 is also provided with a support member 7. The support member 7 in the inner glass tube 2 is provided with a core tube 3, and both the inner glass tube 2 and the core tube 3 are provided with With solar selective absorbing coating4.

[0022] Outer cover glass tube 1, inner glass tube 2, and core tube 3 are arranged sequentially from the inside to the outside. There is a vacuum interlayer 8 between the outer cover glass tube 1 and the inner glass tube 2, and between the inner glass tube 2 and the core tube 3 to facilitate the transfer of heat radiation. . Thermal radiation is the onl...

Embodiment 2

[0026] Embodiment 2: On the basis of Embodiment 1, the core tube 3 extends out of the outer cover glass tube 1 and the outer end of the inner glass tube 2 is provided with a screw thread 9, which is convenient for connecting with other devices through the screw thread 9, and is convenient for heating the inside of the core tube 3 The heat is transferred out and used to achieve the effect of heat collection.

Embodiment 3

[0027] Embodiment 3: On the basis of Embodiment 1, the core tube 3 extends out of the outer cover glass tube 1 and the outer end of the inner glass tube 2 is provided with a flange 10, which is convenient for connecting with other devices through the flange 10, and it is convenient to connect the core tube 3 The heat of the internal heating is transferred out for use to achieve the effect of heat collection.

Abstract

The invention discloses an all glass double-vacuum inner light collecting heat radiation solar collector tube, and belongs to the field of solar energy application. The all glass double-vacuum inner light collecting heat radiation solar collector tube comprises a shell glass pipe, an inner glass pipe and a core tube; the shell glass pipe is internally provided with a supporting piece, and the inner glass pipe is arranged on the supporting piece of the shell glass pipe; a supporting piece is arranged in the inner glass pipe, the supporting piece in the inner glass pipe is provided with the coretube, and both the inner glass pipe and the core pipe are provided with sunlight selective absorbing coatings; and vacuum interlayers are arranged between the shell glass pipe and the inner glass pipe as well as between the inner glass pipe and the core tube. The all glass double-vacuum inner light collecting heat radiation solar collector tube is composed of the shell glass pipe, the inner glasspipe and the in-pipe light collecting heat radiation core tube; light collecting heat radiation is generated inwards through heat energy on an inner-layer light collecting heat radiation film layer of the sunlight selective absorbing coating arranged on the outer wall of the inner glass pipe, thus, heat radiation can penetrate through the inner pipe to heat a working medium or liquid in the coretube, and accordingly, high-temperature heat energy is obtained. The advantages of being resistant to freezing, capable of preserving heat, high in weather-proof performance and heat collecting efficiency, long in service life and the like can be ensured.

Description

technical field [0001] The invention relates to the application field of solar energy, in particular to an all-glass double-vacuum inner concentrating and radiating solar heat collecting tube. Background technique [0002] The all-glass vacuum solar collector tube has become the core component of energy saving, environmental protection, safety and high efficiency in the development and application of solar "photothermal energy". The photothermal application of solar energy has been popularized from family life to applications in various fields such as industry, agriculture, commerce, government agencies, military forces, and colleges and universities. [0003] There are many disadvantages in the existing all-glass vacuum solar collector tubes: Since ordinary all-glass vacuum solar collector tubes cannot be directly applied to medium-high temperature and pressure-bearing operations, only metal small heat pipes or metal U-shaped heat collectors can be used in ordinary collecto...
