Abstract

A simple assembling teaching material for experiencing solar heat is provided.
The present invention is characterized in that a single panel structure is used to form a concave reflecting mirror with a panel-shaped reflecting plate, a structure for inserting and fixing a joint portion of a panel portion, and a reflecting plate having at least one surface mirror-finished. The cutting and assembling was facilitated by printing a cut line, a cut line, and a fold line on the board.
[Effect] As an educational material from elementary school to junior high school, it can be easily and surely assembled, and the principle can be confirmed practically, and there is an effect that the user can experience calorimetry. Also, simple assembly with a single panel structure can be performed without using a plurality of materials for assembly.

Description

  The present invention relates to a solar heat collecting teaching material, and is to provide a solar heat collecting teaching material by forming a concave reflector easily assembled from a single reflecting plate.

Conventionally, it is known that heat is generated by condensing sunlight, and a solar collector that can be disassembled and stored is also known.

JP-A-4-332347

However, assembling, disassembling and storing are not easy, and there are many cases where a plurality of types of materials are used in combination, which is unsuitable as an assembling teaching material.

  The present invention succeeded in seeing the completion of the solar heat collecting teaching material by forming a concave reflecting mirror with a single panel structure and fixing the joint of the panel part, The problem was solved.

In addition, by printing the cutout line and the fold line on the reflection plate, the cutout can be facilitated and the fold line can be formed so that a certain effect (shape accuracy) can be expected.

The present invention is a teaching material for a heat collecting device which can be easily assembled by even a beginner, and can collect heat with a simple device using sunlight.

The purpose of the present invention is to make it possible to experience the generation of heat from solar rays by assembling, but this does not preclude its use as a cooking utensil.

A cutout line and a fold line for panel assembly are printed on one surface of a reflector formed by layering aluminum foil on the surface of a core material of the reflector.

A solar heat collector having a concave reflector formed by a panel-shaped reflector cut out from a reflector, wherein a cutout line and a fold line are printed on the reflector. It is.

An embodiment of the reflector of the present invention will be described with reference to FIG. At least one surface of the core material base plate 1 is laminated with an aluminum foil 2 of the same shape to form a reflection plate 3, and the reflection plate 3 has a cutout line 5 of the panel-like reflection plate and a bottom surface 4 a of the panel-like reflection plate. The cutting line 7 for inserting the insertion panel 7a around the perimeter was printed, and the fold line 8 was printed to constitute the panel-shaped reflector 4 for the solar heat collecting teaching material.

The reflector 3 can be cut along the cut line 5 and cut along the cut line 7 to easily obtain the material 4 of the concave reflecting mirror.

The reflecting plate 4 is cut along the cutting line 5, the separating surface 6 is cut off, and a cut is made in the cutting line 7 to form the panel-like reflecting plate 4, and the fold lines 8 for forming the concave surface are each valley. Then, the cut 7a is inserted into the cutting line 7 for inserting each, and then the cut 9 is attached to the back side of the bottom surface 4a of the reflecting mirror respectively to form a concave reflecting mirror, and heat is absorbed to the central portion. When the body is installed, the peripheral heating tool 10 of the present invention is completed.

According to this invention, it can be easily and reliably produced as a teaching material from an elementary school to a junior high school, and there is an effect that it is possible to experience heat collection from sunlight and calorific value measurement. It can also contribute to global environmental education. Also, the angle of the reflector makes it possible to collect heat particularly effectively in winter when the solar altitude is low.

In addition, although it is a teaching material, it has a practical experience (for example, making boiled eggs) and can also serve as a heat source even when there is a lack of combustion resources (for example, during a disaster), so the educational effect is large.

It is explanatory drawing which shows the manufacturing process of the reflection plate of this invention. It is explanatory drawing which shows the production process of the reflector of this invention.
