Solar water heaters are mainly composed of three parts: a water storage tank, a vacuum collector tube or flat plate collector and a bracket. Primary school students can use a columnar air film as a water storage tank, a columnar air. film or a black pencil or a wooden stick as a vacuum tube, or a wooden stand. Or use modeling clay to make a model of a solar water heater.
I hope this can help you, and I hope you will adopt it, thank you!
Elementary school students making solar water heaters?
1. Materials: boxes (preferably iron boxes), small cans (must be metal), foam, reflective panels (you can use aluminum foil from cigarette boxes, mirrors, CD scraps... ), Adhesive tape, black paint, cellophane.
2. Boxes and small cans should be painted black (this pcould absorb more heat). Dig a hole in the foam (also painted black) that can be inserted vertically into 3/5 of the small can. ((to retain heat), 2/5 are exposed outside to receive sunlight. Put the moss and the small box into the box, seal it with cellophane and make a support frame behind the box so that the box can stand tilted towards the sun. Behind the box, above, install reflectors on the left and right sides. The lower reflector can be placed directly on the ground in front of the box. the better the reflected light).to illuminate the box or small box, so that the box and the box can absorb more heat. A simple solar water heater is made. 1. Materials: box (preferably an iron box), small tin can (must be metal), foam, reflector (you can use du foil from cigarette boxes, mirrors, old CDs. .. …), adhesive tape, black paint, cellophane.
2. Boxes and small cans should be painted black (this can absorb more heat, as black can absorb light). Dig a hole in the foam (also painted black) just enough to insert vertically. the small box contains 3/5 (acts as thermal insulator to prevent heat dissipation), 2/5 is exposed outside to receive sunlight. Put the foam and the small box in the box, seal it with cellophane and make a support. frame behind the box so that the box can face the sun. Place it diagonally and install reflectors on the back, top, left and right of the box. The reflectors underneath can be placed directly on the ground in front of the box (the box). the larger the reflectors, the better, because iThey can absorb more light and heat). The reflected light should be able to shine on the box or small tank so that the box and small tank can absorb more heat. is made.
