Abstract

The invention relates to a hemispherical surface closed daylighting secondary reflection solar water heater. The heater receives solar energy through the reflection focusing function of a large plane reflective mirror and a rotating paraboloid reflective mirror, which can increase the efficiency of receiving solar energy greatly; and the solar energy can be collected and received in either strong light or weak light environment.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a hemispherical closed daylighting secondary reflection solar water heater which utilizes the principle of concentrating light of a rotating paraboloid to receive solar energy. efficiency. 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 in low utilization of solar energy. If the light intensity on the surface of the solar receiving element is doubled...
