Light-concentrating type flat solar water boiler and manufacturing process of light concentrating mirror thereof

Abstract

The invention discloses a light-concentrating type flat solar water boiler and a manufacturing process of a light concentrating mirror thereof. The water boiler comprises a face-folding type parabolic reflecting light-concentrating mirror and a flat heat collector which is arranged on an optical path between the face-folding type parabolic reflecting light-concentrating mirror and a focal point thereof; and the flat heat collector and the face-folding type parabolic reflecting light-concentrating mirror are fixed on an inclined side of a bracket in parallel. According to the invention, two surfaces of the flat heat collector are used as photoreceptive bodies, sunlight irradiating on the face-folding type parabolic reflecting light-concentrating mirror is collected by the face-folding type parabolic reflecting light-concentrating mirror on the back surface of the flat heat collector and then irradiates on the back surface of the flat heat collector and is used for heating the flat heat collector together with direct irradiation of the sunlight in the front, and therefore, the heat collecting efficiency and the heat collecting temperature are improved and water can be boiled to be used as drinking water. The light-concentrating type flat solar water boiler has great practicability.

Description

technical field [0001] The invention belongs to the field of solar heat application, and relates to a flat solar water boiler, in particular to a concentrating flat solar water boiler and a manufacturing process of the concentrating mirror. Background technique [0002] The development and utilization of new energy represented by solar energy has become an effective way for mankind to solve the energy crisis, and it is also the basic energy decision-making of my country's sustainable development strategy. As a kind of green renewable energy, solar energy is inexhaustible. Therefore, whether solar energy is used for large-scale power generation, or for general units or households, it can bring obvious energy-saving effects and social benefits. [0003] Flat-panel solar water heaters are the basic components for the utilization of medium and low temperature solar energy heat. It has large heat absorption area, simple structure and convenient maintenance, and has been widely ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the defects of low heat collection efficiency and low heating temperature of the existing flat solar water heaters, the present invention provides a concentrating flat solar water boiler and a manufacturing process of the concentrating mirror. The column reflects the concentrator to increase the lighting area, and concentrates the sunlight on the back of the flat-panel solar water boiler, and heats the flat-panel solar water boiler together with the direct sunlight on the front of the flat-panel solar water boiler, thereby improving the efficiency of the collector. Heat collection efficiency and heat collection temperature reach boiling level
