Solar energy is made of vacuum tubes, stainless steel water tanks and brackets. Solar water heaters are a major industry in the application of solar energy. They provide people with new environmentally friendly, safe and energy-efficient water heater products. economical and hygienic. Solar water heaters absorb radiant thermal energy from the sun. Cold water heating provides energy-saving equipment that people use in life and consumption. cold water and hot water floating. You can check the water temperature and fill the homemade solar water heater with the appropriate amount of water according to the weather of the day, connect the pipe from the water outlet to the place where the water hot is necessary.
How do elementary school students use simple materials to make a modern solar water heater
Experimental materials: large paper boxr, cotton, small drink bottles, aluminum foil, transparent plastic sheets.
1. Place the bottle in the box and fill it with cotton to prevent heat loss.
2. Use foil to reflect light off the back of the bottle.
3. Cover the water bottle with a transparent plastic cloth on the side facing the light to prevent the water in the bottle from evaporating and being lost
4. be changed to ensure it is always facing the sun
p>
5. Paint the exterior of the box black to absorb solar heat.
How to scientifically make a small solar water heater in the first volume of the fifth grade
Solar water heaters are mainly composed of three parts: a water storage tank , a vacuum collecting tube. or a flat plate collector and bracket. Primary school students can make gaz in column. Use membrane as water storage tank, use columnar air film or black pencil or wooden stick as vacuum tube, and use wooden boards as support. . 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!
1. Find a large saucepan, cover it with small mirrors inside, then find the focal point, make a shelf and put the kettle on it;
2. Boxes (preferably iron), small cans (must be metal, like cans), foam, reflective panels (aluminum from cigarette boxes, mirrors, old CDs...), adhesive tape, black paint, cellophane.
Boxes and small cans should be painted black (this can absorb more heat, as black can absorb light), and a hole should be cut in the foam (which should also be ptinted in black) just enough to be inserted vertically into the small box 3/5 (for thermal insulation 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 be tilted towards the sun. Stand and install reflectors at the back, top, left and right of the box. The reflectors below can be placed directly on the ground in front of the box. the larger the reflectors, the better, as they can absorb more light and heat). The reflected light should be able to illuminate the box or small tank so that the box and small tank can absorb more heat. do.
