Embodiment Construction

[0050] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0051] Such as figure 1 and figure 2 As shown, the present invention provides a filled Fresnel concentrator, comprising an incident plate 1 and several lens threads 2, the incident plate 1 is made of transparent material, the lens threads 2 are made of transparent material, and the lens threads 2 are bonded On one surface of the incident plate 1 , an accommodating space 3 is formed between the lens thread 2 and the incident plate 1 , and the accommodating space 3 is filled with a transparent liquid 4 whose transmittance is greater than 80%.

[0052] After the incident light 100 passes through the incident plate 1, it is refracted by the lens thread 2 and the transparent liquid 4 and becomes refracted light 200, which is focused on the receiving target 300 at the focal plane. A hollow accommodation space 3 is formed inside the...

Abstract

The invention discloses a filling type Fresnel condenser, which comprises an incident plate and a plurality of lens threads, and is characterized in that the incident plate is made of a transparent material; the lens threads are made of a transparent material, the lens threads are attached to one surface of the incident plate, a containing space is formed between the lens threads and the incidentplate, the containing space is filled with a transparent liquid, and the transmittance of the transparent liquid is larger than 80%. According to the Fresnel condenser, the hollow containing space isformed in the lens thread and is filled with the transparent liquid, and the transparent liquid replaces a transparent material to serve as a light-transmitting medium, so that the production cost ofthe Fresnel condenser can be reduced; particularly, when the size of the Fresnel condenser is large, the manufacturing bottleneck of the large-size Fresnel condenser is solved; when the Fresnel condenser is applied to the field of solar heat utilization, the size limitation of an existing solar condenser can be broken through, and the bottleneck of large-scale application of the Fresnel condenserin the field of solar heat utilization is overcome.

Description

technical field [0001] The invention belongs to the field of solar energy concentrating, in particular to a Fresnel concentrator. Background technique [0002] Solar energy is a renewable energy source that is clean, pollution-free, without risk of depletion, and widely available. The research on the utilization of solar energy has attracted widespread attention worldwide. Solar concentrators are key equipment for collecting solar energy resources, and are generally divided into reflective concentrators and transmissive concentrators. Reflective concentrators include tower heliostats, trough concentrators, dish concentrators and reflective line Phillips concentrators, while transmissive concentrators mainly refer to Fresnel lenses. The Fresnel lens was invented by French physicist Augustin Jean Fresnel in 1822. It uses multiple coaxial or parallel prism sequences to form a discontinuous surface instead of the continuous spherical surface of the general lens. It usually uses...
