Abstract

The invention relates to a secondary reflection solar heater with parabolic cylinder surface for gathering light and hollow square closed cavity for daylighting, which receives solar energy through the light reflection and focusing functions of a large-panel reflector and a parabolic cylinder surface reflector. The device can greatly enhance the receiving efficiency of the solar energy and can beused for realizing the collection and the receiving of the solar energy in the environment of hard light and weak light.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a solar water heater with a hollow square closed cavity for secondary reflection parabolic cylindrical surface concentrating to receive solar energy by utilizing the principle of parabolic cylindrical surface concentrating light. Solar energy can greatly improve the receiving efficiency of solar energy. Background technique: [0002] Solar energy is a kind of clean energy, inexhaustible and inexhaustible, and will not cause environmental pollution. Nowadays, whether in coastal cities or inland cities, solar energy products are increasingly entering people's field of vision. Solar street lights, solar lawn lights, solar garden lights, solar corridor lights, bus station lights, traffic lights, etc., all kinds of solar water heaters have also approached thousands of households. However, most of these solar products do not have the function of concentrating light, resulting ...
