Abstract

The invention relates to a double parabolic cylinder reflection collimated-light focusing solar water heater. The heater forms uniform-intensity collimated light of which the intensity is several times of that of sunlight by using the reflection focusing action of the parabolic cylinders, and the collimated light irradiates on the solar receiving device, thereby greatly enhancing the solar energyreceiving efficiency. Thus, the solar water heater can be used for collecting and receiving solar energy at both high and low light levels.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a double parabolic cylinder reflection parallel light focusing solar water heater which utilizes the principle of parabolic cylinder light concentrating to receive solar energy. receiving 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...
