Siheyuan: Starting from the promotion of an engineer

Chapter 186 Extended research and development of solar energy, submitted to the big leader

In order to receive You Yuanshan from the south, Yi Zhonghai didn't invite anyone except Lin Zhen who was helping the cook.

On the one hand, he wanted to have a good talk with You Yuanshan, on the other hand, as an uncle in the courtyard, it was inappropriate to invite this or that.

If you really want to invite people from the courtyard to accompany you, the second and third uncles have to come first.

But one of these two people is addicted to official fans, and the other is stingy.

If you can't say three sentences, you lose your true nature, 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.

He kept talking high and high, and Lin Zhen couldn't find fault with his words of gratitude.

In front of You Yuanshan, Yi Zhonghai couldn't make a move at all.

Being framed by You Yuanshan, he could only nod repeatedly, and responded mechanically.

In the end, You Yuanshan took out another 100 yuan, saying that it was considered as the maintenance fee for his daughter You Fengxia, and he would pay it every year in the future.

This trick made Yi Zhonghai even more overwhelmed.

Get up quickly and refuse, saying that you can't ask for anything.

Director You forced it into Aunt Yi's hands.

Now Yi Zhonghai became honest, and he could never say anything about letting You Fengxia go back to the south.

Regardless of whether it is true or not, what they do on the surface makes it hard for me to make sense of it.

It's just that she is willing to let her daughter take care of her for the elderly.

Besides, if you want to send You Fengxia away, unless you don't want to be loyal and upright, you will have to learn from Xu Damao.

Lin Zhen was amused in his heart, thinking that no matter how much wit and resourcefulness you, Yi Zhonghai, are, you are no match for You Yuanshan.

The pattern of looking at things is here, and the pattern of other people is bigger than yours.

As an eighth-level fitter, your vision and heart cannot be compared with that of a director of the technical department.

If it wasn't for the purpose of finding a permanent residence in the capital for their daughter, they wouldn't have made friends with you at all.

They came this time to give you reassurance, and it's useless if you want to regret it.

Lin Zhen didn't bother to guess what Yi Zhonghai was thinking at this moment.

You Yuanshan finally came here, Lin Zhen didn't want to just let him go.

During the dinner, I talked with him about work.

"Director You, have you mentioned the development of the vacuum glass tube in the past few days?"

You Yuanshan was a bit embarrassed: "I mentioned it, but the superior said that the practicality of the product is too small, the future planning is too long, and the research and development efforts are wasted. It is better to hurry up and produce solar cookers."

Lin Zhendao: "R&D power is not wasted only when designing new products, because the future planning takes a long time, so we have to start as soon as possible, alas, so, I will show you the complete design later, and then ask Yang The factory manager will go to the big leader, and the capital will issue R & D instructions, and your local leaders will have to obey the instructions of their superiors."

You Yuanshan's eyes lit up when he heard this, he wanted to meet the big leader even in his dreams.

If the director of the light industry technology department in a local area can meet the big leaders, he will be more prestigious than the factory director after returning home.

If the local superiors did not approve the project, he came to the capital, and the above directly criticized him, then he would have to go back to the wind and rain.

"Oh! If I can meet the big leader, I'm really worth it this time!"

Lin Zhen smiled slightly and said, "It's just to ask Director Yang to mention, I'm not sure whether the big leader will meet us."

"It's okay, as long as the project is approved, as long as it is approved, the technical department of our glass factory will definitely develop it with all its strength!"

"Okay, I'll go to my house later to look at the design drawings."

Aunt Yi asked, "Lin Zhen, has the guest house been arranged?"

"Don't worry, let Xu Damao finish the check-in formalities."

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 seeing it, but there was a hint of doubt in his eyes.

"Lin Gong, these rows of long tubes are the vacuum glass tubes you asked me to develop? I see your water storage tank is on it, how do you heat it? And it's unrealistic to boil it? What are they used for? ? Cooking? Drinking boiled water? Is the water storage tank too big?"

Although You Yuanshan is the director of the technical department, he is very conservative in the concept of products and can't let go of his guesses. His understanding of products is still limited to the current living habits of people.

Lin Zhen smiled slightly: "This solar water heater, I call it the second-generation extended product of the solar cooker, it is not used to boil water, but to use solar energy to heat water to meet people's daily hot water needs, such as washing Take a hot bath, scald your feet at night, wash your hair in the morning, etc.”

"Uh...how about the heating principle? There seems to be no place to focus."

"The vacuum double-walled glass tube is the heating source. The inner wall is coated with heat-absorbing paint, the outer wall is transparent, and the vacuum layer between the inner and outer walls is a temperature-locking layer. In this way, the water contained in the glass tube will be heated by the sun all the time, and The temperature will not be lost, and using the principle of hot water floating, the hot water in the glass tube will form a cycle 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, even in winter, people can still use hot water."

"Yes, technology changes life and improves people's quality of life."

You Yuanshan was a little puzzled again: "How do you add water to the water storage tank? Where is this kind of water heater usually placed in the house?"

"Water heaters should be placed higher, preferably on the roof, so as not to waste space. Look at the solar cooker, which is now facing the embarrassing situation of occupying too much land. There is no problem in rural areas, and many high-rise residential apartments in the city are used. No."

"Placing solar water heaters on the roof does not take up much space, but it is troublesome to install water."

"Using the tap water in the city, the pressure is enough. In the countryside, you have to use a high-pressure water tank, but it's too early. The glass factory can develop the heating tube within ten years. The pressure tank is also a problem. "

You Yuanshan nodded, "Indeed, after all, the solar cooker has only just come out, and its value has not yet been reflected. At least the use value of the solar cooker has been fully utilized before the promotion of solar water heaters."

Lin Zhendao: "With the development of society, I estimate that the use value of solar cookers will have a peak period of 20 years at most. We strive to promote solar water heaters before solar cookers are eliminated."

"Okay, Lin Gong, you are really a good engineer who works for the benefit of the society. I am really relieved that Fengxia can live in the same hospital with you. I hope you will take care of me in my studies in the future!"

"No problem, it's my job. Tomorrow, we will go to Director Yang and try to get the big leader to approve the development project of the double-walled vacuum glass tube. I asked you to bring the transparent thermos liner. Have you brought it?"

"It's in the luggage, I'll take it for you."

Lin Zhen specially asked You Yuanshan to bring a non-silvered thermos liner.

This is the closest to the heating tube designed by myself.

They are all double-glazed walls with a vacuum in between.

Paint the inner layer black, and you can make a simple solar water heater for the leader.

If you want to convince the big leaders, you have to come up with practical things.

After You Yuanshan delivered the transparent thermos liner, he took his wife and son to the guest house to rest.

The next day, the daughter-in-law and son returned to the south first, and then went back after finishing their business with Lin Zhen.

She also made an agreement with Yi Zhonghai that You Fengxia would take Yi aunt to live in the south for 20 days during the summer vacation.

Yi Zhonghai couldn't go, he had to go to work.

After You Yuanshan left, Lin Zhen worked overtime.

Pour the black paint bought from the supply and marketing company into the inner tank.

After turning it once, the inner wall is all painted black, and it is used for testing temporarily, so the heat-absorbing paint is temporarily replaced with black paint.

For the development of coatings, it 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 80s.

Now it is enough to allow the Southern Glass Factory to develop the heating tube.

As long as it doesn't delay mass production in the 80s.

Early the next morning, Lin Zhen found Deputy Factory Director Li with the design drawings and the painted liner of the thermos.

This matter must be greeted to him first, there is no way, who let himself be under his control now.

If you bypass him and go directly to Director Yang, it will be difficult after a few years.

After listening to Lin Zhen's introduction, Deputy Factory Manager Li clapped his hands in surprise.

"Lin Gong, do you have a computer installed in your mind! Can you think of this product?"

Lin Zhen smiled and said, "Didn't you become obsessed with solar energy when you were researching solar cookers? By the way, Director You Yuanshan of the Southern Glass Factory has come to Beijing. I asked him to bring this thermos liner."

Deputy Director Li nodded and said: "Okay, let's go to Director Yang first, and see if we can go to the big leader together. I believe that after you finish the demonstration, the Southern Glass Factory will immediately have an additional research and development project!"

"In any case, this project is now your responsibility."

Deputy Factory Manager Li narrowed his eyes and said with a satisfied smile: "Okay, okay, I like to be in charge of new projects!"

Director Yang nodded after listening to the introductions of Deputy Factory Director Li and Lin Zhen.

Immediately called the big leader, the big leader asked him to take Lin Zhen only.

Deputy Factory Manager Li was a little disappointed, but he didn't dare to say anything.

Director Yang immediately called a special car and took Lin Zhen to find the leader.

The big leaders have a clear understanding of the development of foreign societies.

He is 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, so that our country's solar energy field will far surpass the international standard!"

Lin Zhen demonstrated again, filling the inner tank of the thermos with cold water and capping the cork.

It was the summer of May at this time, the weather had become hot, and the sun was scorching hot.

The thermos was left for less than 10 minutes.

Just listen to the 'bang'.

The wooden cork flew out, and the water in the thermos liner had reached more than 80 degrees.

Lin Zhendao: "The main purpose of this product is not to boil water, but to meet the daily hot water supply, so a lot of water can be stored in the water tank, and the water heated for a few hours in the morning is enough for a family of six or seven people. "

The big leader nodded and smiled: "The idea of ​​the wind power generator you submitted last time has been developed into a finished product. Now the northwest and coastal areas of the motherland have started trials. I believe that solar water heaters will come out in a few years. Okay, noon Don't leave, you two, eat at my house."

Director Yang smiled and said, "You don't know Xiao Lin is a cook, do you?"

"Oh? Kobayashi can cook?"

Director Yang proudly said: "It's more than knowing how to do it! That's a top-notch proficiency!"
