Target customer group of solar water heaters

Dear, hello ~ I am happy to answer your questions! The target customer groups of solar water heaters are schools and factories. According to the survey, solar water heaters are heating devices that convert solar energy into thermal energy and heat water from low temperature to high temperature to meet people's use of hot water in life and. production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Domestic solar water heatersVacuum tube s 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 heat collecting tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water. Get the hot water you need.

How much electricity can be collected using solar panels from the outer surface of a cup of water.

No:

A thermos cup that displays the temperature, usually on the inside. the cover of the thermos cup, usually installed with a button battery, which can provide power.

Produce electricity using temperature. A battery box is provided outside the cup body to supply electrical power to the heat-sensitive device and the display device ins the cup to display the temperature.

Using the battery as a power source, you can achieve stable voltage, stable current, stable power supply for a long time, and current little affected by the outside world. The battery has a simple function. structure and is easy to transport.

The charging and discharging operation is simple and easy, not affected by external climate and temperature, the performance is stable and reliable, and plays a great role in all aspects of modern social life . Therefore, thermos batteries are generally safer.

Modern Kuafu dives into the sun, why isn't the Parker Solar Probe melting?

The battery power of a piece of 125X125 single crystal silicon is about 2.7W

The outer surface of the water cup is completely fixed and its area Effective is just the projection area under sunlight. , approximately 125*60 or so.

The power is around 1.3 W. This is ideal when the sun is strong.

Assuming the effective sunshine duration is calculated as 4 hours per day, it can generate 1.3*4=5.2wh

Assuming it be used to charge a 5.2wh/5V= 1.04 Ah power bank

That is, it can fully charge a 1.04 Ah power bank ( 1040mah). It is also a theoretical value. In fact, with the loss of charge, even such a small power bank can't do it. be fully charged.

The Parker Solar Probe uses a few tricks to insulate the sun's heat. Although the temperature on the sun-facing side of the Parker probe is very high, the energy absorbed is not high.

The temperature on the surface of the sun reaches 550°C.0°C, the temperature of the corona agitated by solar activity reaches 1 million degrees. The crown can reach a heightude of several million kilometers on the surface of the sun. Therefore, the Parker Solar Probe almost passes through the corona at perihelion. In order to prevent detection, the device was destroyed by high temperatures and researchers had to take special measures.

The environment in which the Parker Solar Probe is located has a very low density of particles in the universe. For example, the corona particle density is about 10^15 particles per cubic meter, which is only one. ten billionth of that of air. Even if the temperature is very low, the heat transferred to the detector by high and low density particles per unit time is very small, and the temperature of the detector shell does not increase rapidly. heat is dissipated over time, the shell temperature can be guaranteed within a certain range.

Just like when we burn firewood, the temperature of the flame reaches500 to 600 degrees Celsius. It's good if we pass our hands over the flames, but when we put our hands in water at 100 degrees Celsius, we will be burned even if the time is short, because the density of particles in water is much higher than that of air and heat transfers very quickly.
