Abstract

The invention relates to a light reflecting device for a solar thermal collector. The light reflecting device comprises an installing frame, supporting rods and a light reflecting plate; the installing frame is a rectangular frame, the supporting rods are transversely arranged on the reverse side of the installing frame, the installing frame is provided with screw holes used for fixing the installing frame, the light reflecting plate is arranged in the installing frame, the edges of the light reflecting plate are fixed to the edges of the installing frame, and the joints of the light reflecting plate and the supporting rods are fixed through bolts. The light reflecting device is characterized in that the light reflecting plate is provided with light reflecting grooves and bending grooves, wherein the light reflecting grooves and the bending grooves are alternately formed, and each light reflecting groove is in a flat V shape. According to the light reflecting device, sunlight can be fully utilized, and the working performance of a water heater is improved; when light rays penetrating among ultraviolet pipes irradiate the light reflecting grooves formed in the light reflecting plate, the light reflecting grooves reflect the light rays to enable part of the light rays to irradiate the reverse sides of the ultraviolet pipes, therefore, the utilization rate of the sunlight can be increased, and meanwhile the working performance of the solar thermal collector can be improved to the maximum.

Description

technical field [0001] The invention relates to a reflective device for a solar heat collector, which belongs to the field of solar energy equipment. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters account for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. During the use of solar water heaters, sunlight cannot shine on the back of the heat collecting tubes, and part of the light passes directly through the gaps between the heat collecting tubes...
