10 years.
According to Baidu's research experience, the lifespan of solar water heaters is 10 years. Although many brands claim their products have a lifespan of up to 15 years, they are usually phased out after 10 years of use because the lifespan of the heating tube is only ten years. If it exceeds ten years, the safety factor decreases. be reduced and the risk of electric shock will easily occur.
The working principle of solar water heaters is that sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the second glass layer, absorbing thus the heat of solar energy. The part is vacuum insulated and heat transfer will be significantly reduced (radiation heat transfer still exists, but there is no thermal conduction or thermal convection). tube, heating the water in the glass tube. The heated water will flow upward along the heating surface of the glass tube and enter the insulated water storage bucket. The relatively low temperature water in the bucket will enter the glass tube along the backlight surface of the glass tube for replenishment. will continue to heat the water in the insulated water storage bucket, thereby achieving the hot water target.
Dutch scientist Wan. Jer. Mel puts forward a shocking hypothesis: our Sun only has 6 years left.
How many years does it have left? The scientist's answer is as follows: the Sun is approximately 4.5 billion years old. During this time, it will consume half of the hydrogen in the solar core. In other words, this “fuel” is enough for the sun to burn for 4 to 5 billion years. This period is so long that people can sit back and relax. However, there is not sofor a long time, the Dutch astrophysicist Wan. Jer. » Mel said in surprise. Based on data on temperature changes in the solar core over the past few years, he came to a frightening conclusion: everything that is happening now in the sun is similar to the changes that took place before the explosion of a supernova. Ten thousand. Jer. Meier estimates that the temperature of the solar core is typically 27 million degrees Fahrenheit, but has increased as high as 49 million degrees in recent years. If the solar core continues to heat at this rate and this process is irreversible, then the sun will inevitably explode in about 6 years.
To understand the consequences of the explosion of the sun, you can observe the changes that occurred on a planet very close to the exploded supernova. Demonstration of image data from the Siberian branch of the Institute of Solar Geophysics: About 8 minutes after the explosion ofsupernova, the entire starry sky was submerged in a huge and terrifying eruption. It can be seen that with the blinding light emitted by the explosion, the invisible X-rays, ultraviolet rays and radiation that arrived together were so powerful that they broke through the protective layer of the atmosphere and instantly killed all the living beings. The radiant energy from the explosion suddenly heated the planet's atmosphere and surface by thousands of degrees. Sea water began to evaporate in large quantities. The planet is enveloped in hot gases. Through the dense fog, a gradually enlarging sphere shimmered, and the night sky was red and purple, forming a terrifying pattern. Clouds of red-hot ionized gas are gradually obscuring the entire starry sky at a speed of several thousand kilometers per second. The red magma from the supernova explosion spread to alightning speed and quickly reached the very nearby planet, causing a devastating disaster. Imagine the sun explodes and planet Earth becomes inhabited, the story will also end. After a long time, the molten radioactive ash on the sleeping planet slowly began to cool.
However, the good news is that the theory of Dutch scientists is only a hypothesis. Russian experts have expressed doubts about this figure: 10,000. Jer. Mayer's conclusion based on the increasing temperature of the solar core sounds scary, but the real situation is exactly the opposite. Continuous satellite records of solar radiation flux over the past decades show that the energy released by the sun, the main energy source of our planetary system, is very stable as in the past. The energy released by the sun per second is approximately 3.84,026 joules. This numberhasn’t changed for at least several decades. In other words, the amount of solar energy that reaches Earth is always the same. Based on geological and historical data, Russian experts estimate that solar radiation has been stable for at least tens of thousands of years, both in the past and today. If this were not the case, Earth would have traces of boiling oceans and global glaciers. Fortunately, the sun's "oven" works without problems.
Let's talk about the strange theories of American scientists. Based on computer calculations, they believe it is possible that Jupiter, the largest planet in the solar system, will interrupt its orbit. The result of this cataclysm was that the earth rushed into the icy abyss of the universe and transformed into a large piece of ice. Of course, this assumption is not realistic in the near future.
Research on the sun only lasts a little more than100 years. Until now, knowledge about the sun was very limited. Only now have solar physicists around the world finally begun large-scale work: creating a standard model of the internal structure of the sun.
As for the claim that the sun is about to be destroyed, Russian scientist Sergei. Yazel wants to sleep with Wan. Jer. Mel bets. If after three years the astrophysicist discovers obvious characteristics consistent with the views of Dutch scientists, he will lose $10,000, otherwise he will make money.
