Embodiment Construction

[0009] The structure of an arc-shaped energy gathering cover of the present invention will be further elaborated below with reference to the accompanying drawings.

[0010] An arc-shaped energy gathering cover, including a cover body composed of a hemispherical shell 3 and a light-heat radiation reflection layer 4, the light-heat radiation reflection layer 4 is made of ceramics, the hemispherical shell 3 and the light-heat radiation reflection layer 4 Form heat-insulating layer 2 between, the cavity in the photothermal radiation reflection layer 4 is energy collection chamber 5, also be provided with beam incident hole 1 at the bottom of hemispherical housing 3, the area of ​​beam incident hole 1 can be made minimum, prevents loss of energy.

[0011] When working, when a light beam enters through the beam entrance hole 1, a part of the light will be reflected. At this time, the photothermal radiation reflective layer 4 will reflect this part of the light back to the solar coll...

Abstract

The invention relates to an arc energy concentrating cover, in particular to an energy concentrating cover suitable for a solar heat collecting device, and belongs to the technical field of development and utilization of solar energy. The arc energy concentrating cover comprises a cover body consisting of a hemispherical shell and an optothermal radiation reflection layer. An insulating layer is formed between the hemispherical shell and the optothermal radiation reflection layer. A cavity in the optothermal radiation reflection layer is an energy collecting cavity. The bottom of the hemispherical shell is also provided with beam incidence holes. The arc energy concentrating cover of the invention is a double-layer heat preservation device body, can realize adsorption and utilization of energy reflection, enables the light almost totally adsorbed and effectively reduces energy drain.

Description

1. Technical field [0001] The invention relates to an arc-shaped energy-gathering cover, in particular to an energy-gathering cover suitable for solar heat collecting devices, and belongs to the technical field of solar energy development and utilization. 2. Background technology [0002] With the shortage and non-renewable energy, people have turned to use natural conditions to obtain energy, such as wind energy, solar energy, geothermal energy, etc., among which solar energy is used the most, but the energy-gathering covers used in many solar heat collectors often cannot To fully exert its effect, the energy loss due to the effect of reflection is very large. 3. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the previous energy-gathering covers, and provide an arc-shaped energy-gathering cover that is simple in structure, easy to use, and capable of efficiently absorbing solar energy. [0004] An arc-shaped ene...
