Retired Engineer Designs Increased Collector Area of ​​Threaded Solar Collector
 |
Lou Garden is producing thread-collecting tube blanks.
The retired engineer of the Machinery Industry Department of Jiangsu Province, Lou Louyuan, has more than 60 inventions and 13 Chinese patents. Recently, the 69-year-old civil inventor broke news again. After nearly five years of hard work, he carefully designed and developed one. The highly efficient solar vacuum collector tube project was recently granted a patent by the State Intellectual Property Office. This patent changed the conventional linear heat collection vacuum tube to a threaded heat collection tube and became a domestic initiative.
He "changed the vacuum tube into a song"
This year's 69-year-old Lou Lou Garden is located in Loujia Village, Shijie Town, Shengzhou City, Zhejiang Province. It invented a leak-proof ball plug for toilets 26 years ago, which solved the problem of leakage of toilets and became a sensation in the country. Since then he has always been invented.
After retiring from the Jiangsu Machinery Department in 1998, Lou Louyuan chose Ye Lai to return to their hometown and lived in his hometown, Loujia Village. Although he was retired, he did not stop innovating. In previous years, he accidentally discovered in his own accidental cracking solar tube that the inner tube had weak spots such as small light receiving area and unsatisfactory heating up, which led to the idea of ​​optimizing the solar vacuum collector tube. After searching for information and hundreds of tests, it was finally Developed into a high-efficiency solar vacuum collector tube, which was approved by the national patent office for acceptance earlier.
New type of collector tube heat collection area increased by half
Lou Louyuan told reporters that the solar water heater collector tube used by people today was invented by Tsinghua Sunshine in 1984. The solar vacuum collector tube he designed and developed overcomes the problems of slow heating, small collector area, and affecting users' winter use. , And the structural design is simple and reasonable, easy to make; In addition, its external dimensions standard universal, fully meet the needs of the existing solar water heater replacement, without changing the water heater size, you can directly install and use.
This novel heat collector adopts a continuous arc-shaped screw thread design, which increases the light-collecting and collecting area by 50%. According to relevant experts' predictions, if the collector tubes invented by Louyiyuan are promoted nationwide, the country can save 10 million tons of standard coal per year and reduce the emission of carbon dioxide, sulfur dioxide and dust by 15 million tons. This will not only save energy but also help promote the rapid development of the solar energy industry. .

The invention of him 20 years ago is still in use
The reporter learned from the interview that the first patented product of Lou Lou was a patented leak-proof ball plug for toilet bowls in 1987, and it has been used for more than 20 years. The reason for this invention was that the leakage of toilets was very serious at that time. The floor laborers who were diligent in thinking discovered that the main reason for the leakage of toilets was the unreasonable design of the ball plug structure, the high center of gravity, and the improper layout of the cavity space. He invented the toilet leakproof ball with the shape of a flat round persimmon; there is a ring of annular cavity around the upper end; the lower part of the ball is semicircular, which reduces the center of gravity and height of the ball, increases the buoyancy and stability around the ball, and effectively prevents The toilet leak problem. This new patent is applicable to the renovation, maintenance and support of the leak-proof toilet tank. It is an effective water-saving device with a simple structure and convenient manufacturing.
