The solar water heater is a device that uses solar energy to heat and store hot water. It has the advantages of energy saving, environmental protection and ease of use. The treatment method mainly includes the following steps:
1. Material selection: The materials of solar water heaters mainly include glass, metal, plastic, etc. Choose suitable materials according to different needs and conditions of use.
2. Making a Solar Collector: The solar collector is the main component of the solar water heater and is made of glass and metal. Firstly, the metal plate is cut and drilled, then the metal plate is coated with light and heat absorbing paint, and then the glass is fixed on the metal plate to form a heat collector.
3. Make a Water Tank: The water tank is the dIt is the water storage device of the solar water heater and is usually made of plastic or metal. During production, cutting and welding are carried out according to different materials, then the faucets and drains are installed.
4. Assembly: Assemble the prepared solar collector and water tank, connect the pipes, then fix the whole equipment in the appropriate position.
5. Accessories assembly: According to different user needs, install accessories, such as thermometers, levels, etc.
6. Test: Place the solar water heater in a suitable place, use water to test, and check whether the equipment works normally.
After the above steps, the production of the solar water heater is completed. However, since the processing of solar water heaters requires certain technical and technical knowledge, it is recommended to rely on manufacturers orprofessional technicians to guide you during treatment.
How to produce simple solar energy for 5th grade primary school students?
Materials required: cardboard, aluminum foil, wood shavings or strips, scissors, handsaw, white glue, glass tube or clear plastic tube
Steps:
1. First make a support with wood chips, as shown below.
2. Then fold the cardboard and stick it to the backing with white glue as shown in the picture below.
3. Use white glue to glue the foil to the cardboard as shown below.
4. Adjust the angle of the cardboard and foil to form a concave arc, as shown below.
5. Cut two pieces of wood the same length as the glass tube to make a support. Stick it in the middle of the backing as shown below.
6. Install a pole that can adjustr the angle of the concave arc behind the support and the cardboard. Fill the glass tube with water, place it on the stand and adjust the angle of the concave arc so that the glass tube is right at the focus of the reflector reflecting the sunlight, as shown in the 'image below.
Steps:
1. Paint the can or bottle black to better absorb heat.
2. Dig a hole in the foam and insert part of the bottle or can into the foam. The goal is to retain heat. The other part is exposed to the outside to receive heat.
3. Create a support frame behind the box or bottle so that the box can be tilted toward the sun.
4. Install reflectors around the box or bottle (top, bottom, left and right) so that it can fully receive the heat.
5. After production is completed, simply place it in a safe place.sunny.
Preparation of materials:
Cardboard, plastic foam or cotton, plastic bag or drink bottle that can hold water, glass or plastic film, box lid, black paper , mirror or aluminum foil etc.
Principle:
Solar water heaters mainly provide heating by absorbing heat from the sun, and at the same time achieve the function of heat preservation through insulation of the inner tank and vacuum tubes. Only these two points can be resolved. Common homemade solar water heaters use black plastic drums, iron drums, or paint the outside of the drum with black paint to achieve rapid heat absorption.
