Chapter 186 Extended research and development of solar energy, submitted to big leaders
In order to receive You Yuanshan from the south, Yi Zhonghai did not invite anyone except Lin Zhen, who was helping the cook.
On the one hand, he wanted to have a good talk with You Yuanshan, but on the other hand, as the first uncle of the courtyard, it was inappropriate to invite this person but not that one.
If we really want to invite people from the courtyard to accompany us, the second uncle and the third uncle must come first.
But one of these two people is addicted to officialdom, and the other is stingy.
If you can't say more than three sentences, your true nature will be revealed, which is too cheap.
Therefore, Lin Zhen was the only outsider at the dinner table.
You Yuanshan talked with Yi Zhonghai for a while and quickly figured out Yi Zhonghai's character.
Lin Zhen couldn't find any faults with his compliments and words of gratitude.
In front of You Yuanshan, Yi Zhonghai couldn't make any moves.
Being framed by You Yuanshan, he could only nod his head and respond mechanically.
Finally, You Yuanshan took out another hundred yuan, saying that it would be used as child support for his daughter You Fengxia, and he would pay it every year in the future.
This move made Yi Zhonghai even more unable to resist.
He quickly stood up and refused, saying that he could not ask for anything.
Director You forced it into Aunt Yi's hand.
Now Yi Zhonghai was honest and could no longer say anything to ask You Fengxia to return to the south.
Regardless of whether it's true or not, what others do on the surface makes it hard for me to find fault.
He is willing to let his daughter support him in his old age.
Besides, if I want to send You Fengxia away, unless I don't want to be loyal and upright, I will completely break the rules and imitate Xu Damao.
Lin Zhen was amused in his heart, thinking that no matter how hard you and Yi Zhonghai fight, you are still no match for You Yuanshan.
The way we look at things is here, and other people's ways are bigger than yours.
As an eighth-level fitter, your vision and mind are incomparable to that of a director of the technical department.
If they weren't seeking a capital city residence for their daughter, they wouldn't be friends with you at all.
I'm here just to give you reassurance. It's useless for you to regret it.
Lin Zhen was too lazy to guess what Yi Zhonghai was thinking at this time.
You Yuanshan finally came here once, and Lin Zhen didn't want to let him go just like that.
During the dinner, I talked with him about work matters.
"Director You, have you mentioned the development of vacuum glass tubes in the past few days?"
You Yuanshan was slightly puzzled: "I mentioned it, but my superiors said that the practicality of the product is too small, the future plan is too long, and it is a waste of research and development efforts. It is better to hurry up and produce solar cookers."
Lin Zhen said: "R&D efforts are not wasted only when designing new products. Just because future planning takes a long time, we have to start as early as possible. Well, in this way, I will let you see the complete design drawing later, and then ask Yang
The factory director goes to the top leaders, and the capital city issues R&D instructions, and your local leaders have to obey the instructions from their superiors."
You Yuanshan's eyes lit up after hearing this. He had always dreamed of meeting the big boss.
If the director of a local light industry technology department can meet a ministerial leader in the capital, he will be more powerful than the factory director when he returns home.
If he comes to the capital for a project that has not been approved by local superiors, and the top leaders directly give instructions, then he will be in trouble even more when he returns.
"Oh! If I can meet the big leader, this time will be really worth it!"
Lin Zhen smiled slightly and said: "Just ask Factory Director Yang to mention it. I'm not sure whether the senior leaders are willing to see us."
"It's okay, as long as the project can be approved, as long as it is approved, the technical department of our glass factory will do its best to develop it!"
"Okay, I'll go to my house later to look at the design drawings."
Aunt One asked: "Lin Zhen, have the arrangements for the guest house been made?"
"Don't worry, Xu Damao has already completed the check-in procedures."
After dinner, Yi Zhonghai and his wife chatted with You Yuanshan's wife and son.
Lin Zhen took You Yuanshan home to discuss work matters and took out the design sketch of the solar water heater.
You Yuanshan nodded slightly after looking at it, but there was a trace of doubt in his eyes.
"Forest engineer, these rows of long tubes are the vacuum glass tubes you asked me to develop? I see your water storage tank is on top. How do you heat it? And it is not realistic to boil this, right? What is it used for?
?Cooking? Drinking boiling water? Is the water tank too big?"
Although You Yuanshan is the director of the technical department, he has a very conservative concept of products and cannot let go of speculation. His understanding of products is still based on current people's living habits.
Lin Zhen smiled slightly and said: "This solar water heater, I call it a second-generation extension of the solar cooker. It is not used to boil water. It just uses solar energy to heat water to meet people's daily hot water needs, such as washing.
A hot bath, a foot bath at night, a hair wash in the morning, etc.”
"Uh... what's the principle of heating? There seems to be no place to focus the light."
"The vacuum double-walled glass tube is the heating source. The inner wall is coated with heat-absorbing paint, and the outer wall is transparent. The vacuum layer between the inner and outer walls is a temperature-locking layer. In this case, the water contained in the glass tube will be continuously heated by sunlight, and
Without losing the temperature, and using the principle of hot water floating up, the hot water in the glass tube will circulate with the cold water in the water storage tank, and soon the water in the entire water storage tank will become hot water."
You Yuanshan nodded in surprise, "If the water storage tank is well insulated, people can use hot water even in winter."
"Yes, technology changes life and improves people's quality of life."
You Yuanshan was a little confused and asked: "How to add water to the water storage tank? Where is this kind of water heater usually placed in the home?"
"The water heater must be placed higher, preferably on the roof, so as not to waste space. Look at solar cookers, which are now facing the embarrassing situation of occupying too much space. There is no problem in rural areas. Many high-rise residential apartments in the city use them.
No."
"Putting the solar water heater on the roof doesn't take up much space, but it will be troublesome to fill the water supply."
"This uses tap water in the city, and the pressure is enough. In rural areas, you have to use high-pressure water tanks. But it's still too early. The glass factory can develop the heating tube within ten years. Pressure tanks are also a problem.
"
You Yuanshan nodded, "Indeed, after all, solar cookers have just come out, and their value has not been reflected yet. At least, we cannot promote solar water heaters until the use value of solar cookers is almost fully realized."
Lin Zhen said: "With the development of society, I estimate that the use value of solar cookers will have a peak period of up to 20 years. We strive to promote solar water heaters before solar cookers are eliminated."
"Okay, Lin Gong, you are really a good engineer who benefits society. I am so relieved that Fengxia can live in the same hospital as you. I hope you will take more care of her in her studies in the future!"
"No problem, it's my job. Tomorrow we'll go to Factory Director Yang and try to get the senior leaders to approve the development project of double-walled vacuum glass tubes. Have you got the transparent thermos liner I asked you to bring?"
"It's in the luggage, I'll get it for you."
Lin Zhen specially asked You Yuanshan to bring a non-silver-plated thermos liner.
This is the heating tube closest to what I designed.
They are all double-glazed walls with a vacuum in the middle.
By painting the inner layer black, you can make a simple solar water heater for the boss.
If you want to convince big leaders, you must come up with something practical.
After You Yuanshan delivered the transparent kettle liner, he took his wife and son to the guest house to rest.
The next day, my daughter-in-law and son went back to the south first, and then went back after finishing their affairs with Lin Zhen.
He also made an agreement with Yi Zhonghai to let You Fengxia take Aunt Yi to the south to live for ten or twenty days during the summer vacation.
Yi Zhonghai can't go, he still has to go to work.
After You Yuanshan left, Lin Zhen worked overtime.
Pour the black paint bought from the supply and marketing cooperative into the inner tank.
After turning it once, the inner wall was completely painted black. It was temporarily used for testing, so black paint was used to temporarily replace the heat-absorbing paint.
For the development of coatings, we can wait until the double-walled vacuum glass tube is developed.
After all, the real promotion of this solar water heater will have to wait until the 1980s.
Now it is enough to allow Nanfang Glass Factory to develop heating tubes.
As long as it doesn't delay mass production in the 1980s.
Early the next morning, Lin Zhen went to Deputy Director Li with the design drawings and the painted thermos flask liner.
You have to tell him about this matter first. There is no other way. Who can let him take charge of it now?
If we bypass him and go directly to Factory Director Yang, things will become difficult in a few years.
After listening to Lin Zhen's introduction, Deputy Director Li clapped his hands in surprise.
"Gong Lin, do you have a computer installed in your head? Can you come up with this product?"
Lin Zhen smiled and said: "Didn't you become obsessed with solar energy when you were studying solar cookers? By the way, Director You Yuanshan of the Southern Glass Factory came to Beijing, and I asked him to bring this thermos bottle liner."
Deputy Director Li nodded and said: "Okay, let's go to Director Yang first and see if we can go to the senior leaders together. I believe that after you finish your demonstration, the Southern Glass Factory will have another R&D project immediately!"
"In any case, you are still responsible for this project."
Deputy Director Li narrowed his eyes and said with a satisfied smile: "Okay, okay, I like to be in charge of new projects!"
Director Yang nodded repeatedly after listening to the introductions of Deputy Director Li and Lin Zhen.
He immediately called the big boss, who asked him to take only Lin Zhen with him.
Deputy Director Li was a little disappointed, but he didn't dare to say anything.
Factory Director Yang immediately called a special car and took Lin Zhen to find the leader.
Big leaders have a thorough understanding of the development of foreign societies.
He was in favor of Lin Zhen's solar water heater development project.
"This thing will definitely become a necessity for most families, and its popularity will definitely exceed that of solar cookers. We can start research and development work to make our motherland far beyond the international level in the field of solar energy!"
Lin Zhen gave another demonstration, filling the inner container of the thermos bottle with cold water and capping the bottle.
It was summer in May, the weather had become hot, and the sun was scorching.
The thermos bottle was left for less than twenty minutes.
Just hear a 'bang' sound.
The wooden cork flew out, and the water in the thermos bottle had reached over eighty degrees.
Lin Zhen said: "The main purpose of this product is not to boil water, but to meet daily hot water supply. Therefore, a lot of water can be stored in the water tank. By heating water in a few hours in the morning, it is enough for a family of six or seven people."
The big leader nodded and smiled: "The wind turbine idea you submitted last time has been developed into a finished product. Now it has been trialed in the northwest and coastal areas of the motherland. I believe that solar water heaters will be available in a few years. Okay, noon You two, don’t leave and have dinner at my house.”
Director Yang smiled and said, "You still don't know that Xiao Lin is a cook, right?"
"Oh? Xiaolin knows how to cook?"
Factory Director Yang said proudly: "It's more than knowing how to do it! That's a top-notch proficiency!"
