What energy does a solar water heater convert light energy into?

Solar water heaters convert light energy into thermal energy. The relevant content is as follows:

Solar water heaters are divided into vacuum tube solar water heaters and flat plate water heaters. -plate solar water heaters according to their structural shapes. The main evacuated tube solar water heaters occupy 95% of the domestic market share.

Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.

1. Renewable energy

Solar energy generally refers to the radiant energy of thein sunlight. Solar energy is a renewable energy source in the broad sense. Energy on earth is the source of many energies on earth, such as wind energy, biomass energy, tidal energy, water potential energy, etc. The basic methods of using solar energy can be divided into four categories: thermal light use, electric light use, chemical light use, and biological light use . Among the four types of solar energy utilization methods, light-to-heat conversion technology is the most mature, has the most products, and is relatively inexpensive.

Such as: solar water heaters, water boilers, dryers, solar cookers, solar greenhouses, solar rooms, solar desalination devices and solar heating and cooling devices, etc.

Sola energy productionThermal ire has a higher solar energy conversion efficiency than photovoltaic power generation, but its application is not yet common. In photothermal conversion, the application of solar water heaters has the widest application range, the most advanced technology and the best economy.

2. Working principle

Sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the tube. second layer of glass. The thermal absorption of solar energy will be significantly reduced due to the vacuum insulation between the two glass layers (radiant heat transfer still exists, but there is no heat conduction or thermal convection) .

Most of the heat can only be transferred to the water in the glass tube, causing the water in the glass tube to warm up. L'Heated water will move gently upward along the heating surface of the glass tube and. Enter the insulated water storage bucket. The temperature in the bucket will be relatively high. The bottom water enters the glass tube along the backlight surface of the glass tube for replenishment. heated, thus achieving the purpose of hot water.

The forms of energy and the methods of use are different.

1. Energy form: Light energy refers to the irradiation of objects by the sun, which is a kind of radiation energy, while solar energy refers to the conversion of solar radiation into forms of energy to use, including light. energy and thermal energy.

2. Usage method: Light energy is used by converting solar energy into kinetic energy, converting light energy into chemical energy through plant photosynthesis, or by converting light energy into electrical energy via solar panels and solar energy. the use of solar energy is even more widespread. In addition to light energy conversion, the sun's thermal energy can also be directly used for heating, drying, etc.
