Abstract

The invention provides a solar water heater daylighting by a secondary reflective parabolic cylinder light-gathering rectangular flat pipe closed cavity, which receives solar energy by means of reflective focusing effect of a large-plane reflector and a parabolic reflector, thus greatly improving receiving efficiency of solar energy and realizing the acquisition and receiving of solar energy under strong light and weak light environment.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a solar water heater with a double-reflection parabolic cylindrical surface concentrating rectangular flat tube closed cavity for daylighting by using the principle of parabolic cylindrical surface concentrating to receive solar energy. Receiving 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 ...
