In order to receive You Yuanshan from the south, Yi Zhonghai did not invite anyone except Lin Zhen, who helped the cook.

On the one hand, he wanted to have a good talk with You Yuanshan, and on the other hand, as the first uncle in the courtyard, it was inappropriate to invite this or not that.

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

But one of these two people is addicted to officials, and the other is addicted to picking doors.

If you can't say three sentences, you will miss your nature, which is too cheap.

Therefore, there was only Lin Zhen as an outsider at the dinner table.

You Yuanshan talked with Yi Zhonghai for a while, and soon figured out Yi Zhonghai's character.

The words of praise and elevation kept talking, and the words of gratitude made Lin Zhen unable to find fault.

Yi Zhonghai was in front of You Yuanshan, and he couldn't hand over the move at all.

was erected by You Yuanshan and could only nod again and again, responding mechanically.

In the end, You Yuanshan took out another 100 yuan, saying that it was calculated as the child support for his daughter You Fengxia, and he would give it every year in the future.

This move made Yi Zhonghai even more unbearable.

Quickly got up and excused himself, saying that he couldn't ask for anything.

Director You just stuffed it into the hands of Aunt 1.

Now Yi Zhonghai is honest, and he can't say anything to let You Fengxia go back to the south.

Regardless of whether it is true or not, what people do on the surface makes themselves unreasonable.

is willing to let her daughter provide for her own retirement.

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

Lin Zhen was amused in his heart, thinking that no matter how much you Yi Zhonghai fights wits and scheming, he is not You Yuanshan's opponent.

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

You are an eighth-level fitter, and your vision and heart cannot be compared with a technical director.

If it weren't for the fact that they were trying to get a capital hukou for their daughter, they wouldn't have befriended you at all.

People came this time to reassure you, and it's useless if you want to regret it.

What Yi Zhonghai thought in his heart at this time, Lin Zhen was too lazy to guess.

You Yuanshan finally came once, and Lin Zhen didn't want to let him go like this.

During the dinner, I talked to him about work.

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

You Yuanshan was a little embarrassed: "I mentioned it, but the superior said that the practicability of the product is too small, the future planning is too long, and the R&D strength is wasted, so it is better to pay attention to the production of solar cookers." ”

Lin Zhen said: "R & D strength is only in the design of new products is not called waste, just because the future planning time is long, to start as soon as possible, alas, in this way, I will let you see the complete design drawing, and then Tuo Yang factory director to find the big leader, from the capital to issue R & D instructions, your local leaders have to obey the instructions of the superiors." ”

You Yuanshan's eyes lit up when he heard this, he dreamed of meeting the big leader.

If the director of a local light industry technology department can meet the ministerial-level leaders of the capital, he will be more majestic than the director of the factory when he returns.

If the local higher-ups do not approve the project, he comes to the capital and the big leader directly gives instructions, then he will have to be even more windy and rainy when he goes back.

"Oops! If I can meet the big leader, I will be really worth it this time! ”

Lin Zhen smiled slightly: "Just let Director Yang mention it, whether the big leader will see us or not, I'm not sure." ”

"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 and look at the blueprints later."

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

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

After eating, 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 trace of doubt in his eyes.

"Lin Gong, this row of long tubes is the vacuum glass tube you asked me to prepare to develop? I see your water tank on it, how do you heat it? And it's not realistic to boil it, right? What is it used for? Cook? Drink boiled water? Is the water tank too big? ”

Although You Yuanshan is the director of the technical department, he is very conservative about the concept of products, and he can't let go of his conjectures, and his understanding of products is still stuck in the current people's living habits.

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

"Uh...... What about the heating principle? It seems that there is no place for spotlight. ”

"The glass tube with vacuum double wall is the heating source, the inner wall is coated with heat-absorbing coating, the outer wall is transparent, and the vacuum layer between the inner and outer walls is the temperature lock layer, so that the water in the glass tube will be heated by the sun all the time, and the temperature will not pass, and then use the principle of hot water floating, the hot water in the glass tube will form a circulation with the cold water in the water storage tank, and the water in the entire water storage tank will soon become hot water."

You Yuanshan nodded in surprise, "If the water storage tank is well insulated enough, even in winter, people can use hot water." ”

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

You Yuanshan was a little puzzled again: "How to add water to the water storage tank?" Where is this water heater usually placed in the home? ”

"The water heater has to be placed high, it is best to put it on the roof, so that there is no waste of space, you look at the solar stove, now it is facing the embarrassing situation of covering too much land, there is no problem in the countryside, and many high-rise residential apartments in the city cannot be used."

"The solar water heater is placed on the roof of the house, but it doesn't take up space, but it is troublesome to get water."

"This uses tap water in the city, the pressure is enough, in the countryside, you have to use high-pressure water tanks, but it is still too early, the glass factory can develop the heating pipe in ten years, and the pressure tank is also a problem."

You Yuanshan nodded, "Indeed, after all, the solar cooker has just come out, and the value has not yet been reflected. ”

Lin Zhen said: "With the development of society, I estimate that the use value of solar cookers will be prosperous for a maximum of 20 years, and we strive to promote solar water heaters before solar cookers are eliminated." ”

"Okay, Lin Gong, you are really a good engineer for the benefit of the society, Feng Xia can live in the same hospital with you, I am so relieved, I hope you will take care of it in the future!"

"No problem, I'm in charge, tomorrow we will go to Director Yang together, and strive to get the big leaders to approve the development project of double-wall vacuum glass tubes, I let you bring the transparent thermos liner, do you bring it?"

"In the luggage, I'll bring it to you."

Lin Zhen specially asked You Yuanshan to bring a warm pot liner without silver plating.

This is the closest thing to the heating tube I designed.

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

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

If you want to convince the big leader, you have to come up with something practical.

After You Yuanshan sent the transparent pot liner, he took his daughter-in-law and son to the guest house to rest.

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

and agreed with Yi Zhonghai that he would let You Fengxia take Aunt 1 to live in the south for one 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 you bought from the supply and marketing cooperatives into the inner tank.

After turning it once, the inner wall is all painted black, which is temporarily used for experimentation, and black paint is used to temporarily replace the heat-absorbing paint.

For the development of coatings, it is possible to wait until the development of double-wall vacuum glass tubes.

After all, the real promotion of this solar water heater will have to wait until the 80s.

Now it is enough to enable the Southern Glass Factory to develop heating tubes.

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

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

You have to say hello to him first, there is no way, who will let him take care of it now.

If you get past him and go directly to Director Yang, it will be difficult to do it in a few years.

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

"Lin Gong, do you have a computer in your head? Can you come up with this product? ”

Lin Zhen said with a smile: "Isn't it that when you were studying the solar cooker, you were obsessed with solar energy?" By the way, Director You Yuanshan of the Southern Glass Factory came to Beijing, and I asked him to bring this thermos liner. ”

Deputy Director Li nodded and said: "Okay, let's go to Director Yang first, see if we can go to the leader together, I believe that after you finish the demonstration, the Southern Glass Factory will immediately have one more R&D project!" ”

"Either way, it's up to you to take charge of the project now."

Deputy Director Li narrowed his eyes and smiled with satisfaction: "Okay, okay, I like to be in charge of new projects!" ”

After listening to the introductions of Deputy Director Li and Lin Zhen, Director Yang nodded again and again.

immediately called the big leader, and the big leader asked him to only take Lin Zhen with him.

Deputy Director 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 very thorough view of the development of foreign society.

He is very much in favor of Lin Zhen's solar water heater development project.

"This thing will definitely become a necessity for most families, and the popularity is definitely more than that of the solar cooker, and the development work can be started, so that our motherland far exceeds the international standard in the field of solar energy!"

Lin Zhen made another demonstration, filled the thermos with cold water and corked the bottle.

It's summer May, the weather is already hot, and the sun is scorching.

The thermos sat for less than twenty minutes.

Just listen to the 'bang'.

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

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

The big leader nodded and smiled: "The idea of the wind turbine you submitted last time has been developed into a finished product, and now the northwest and coastal areas of the motherland have begun to try it, I believe that the solar water heater will come out in a few years, okay, don't leave at noon, let's eat at my house." ”

Director Yang smiled: "You still don't know that Xiaolin is a cook, right?" ”

"Oh? Can Kobayashi cook? ”

Director Yang said proudly: "Why don't you do it!" That's the best at the top! ”
