JP2007139399A - Rectangular parabolic reflector by means of multiple mirrors - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a rectangular parabolic reflector by means of multiple mirrors, that is simple and capable of making economy compatible with efficiency. <P>SOLUTION: A bookshelf-shaped box is sealed with glass so that mirror surface will not be contaminated, and an actuator is controlled by a computer so that multi-mirrors focus one point, thereby reducing the installation area and also serving, as a wall. The reflector is divided into many parts and made as a reflecting surface as a whole, to function as a focusing concave mirror, and a heat pipe is also used, thereby making economy, and efficiency, compatible, in a simple manner. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a solar heat collector that performs solar tracking while fixing a focal point.

There have been solar water heaters on the roof in glass.

Large parabolic reflectors have a depth and are not suitable for home use. The vertical rectangular reflector is sealed with glass so that the mirror in the dust is not fogged. Charge the lead acid battery with a solar panel or small wind generator. There are rainy days and windy days, but if you look at the span of one year, the movement is self-sufficient. 100V is not used.

If you divide the reflector into many parts, attach them to each based on an actuator, and control it with a computer, the mirrors in the book-box-shaped rectangle will be at the same angle as the parabolic reflector at each point, and the focus will be on the north side Fit a spherical heat pipe about 2m high.

  Sunlight hits the heat pipe at right angles and is efficient and effective. There is also a danger to it, and the protective fence near the focal point needs to be perfect.

A parabolic antenna is desirable, but because it is strange and unfamiliar to place in the home, put many mirrors in a bookcase-shaped glass box and seal with glass so that the mirror does not fog, computer controlled parabolic The angle is the same as the reflector surface. If you install the solar tracking triangular prism-shaped solar cells of Japanese Patent Application No. 2004-343045 and connect them in series and charge them to automobile batteries, or if you use a small wind power generator together, it will be 100V in a span throughout the year. AC is not required and all power is self-sufficient.

Claims (1)

  Normally, a single mirror can be used as a reflector, but a large number of small reflectors, each of which has a triangular prism shape with three outer surfaces as reflectors, are equipped with actuators and are controlled by a computer. If you make a parabolic reflecting surface, focus on one point by tracking the sun, the mirror on the adjacent surface will be at the first position even if you turn about 120 degrees a day and stop after returning from sunset. The next day, the next day's mirror will immediately follow the sun. Since it moves only in the daytime and rotates once in three days, the total power for tracking can be saved significantly. This is similar to Japanese Patent Application No. 2004-343045, but the arrangement of the mirrors is almost flat (needs some depth to make the mirror's triangular prism roll out). If you become a solar collector and focus on the north heat pipe, the bath will boil and the steam heating in the house will meet. However, in order to prevent danger, an obstacle that does not damage the optical path is placed near the focal point, and the focal point height is 2 m or more. A parabolic reflector with a large diameter makes it uncomfortable to place in a home, but if it is a rectangular parabolic mirror with a small box-like depth, it is easy to install in each home as a bowl without any sense of incongruity. A solar collector with the structure and effects described above.
