Chapter 756

On the other side, Yang Xu's mouth slowly opened and slowly closed as he watched the engineers embracing with excitement and cheering, as well as the temperature time function curve with no egg law.

Is this the strength of the fields prize winner?

No wonder the Nobel Committee is overwhelmed by his ability

It's no wonder that the whole computational materials circle is crazy about his theory

Once upon a time, Yang Xu thought that he was close to the Nobel Prize, especially after he won the "citation laurel Award" known as the "Nobel Prize weathervane" with the positive material of lithium sulfur battery and SG-1 superconducting material.

The reason why the Nobel Prize committee didn't consider him was that the name of the paper cooperator was too dazzling. Sooner or later, he could come up with his own achievements and complete the qualitative change through the accumulation of quantity!

Now, however, he felt a deep sense of powerlessness.

Looking at himself reflected on the floor to ceiling window, Yang Xu shook his head with a headache and a smile.

It's monsters who can win the Nobel Prize

Sure enough, I'm still far away

At this moment, his distant thoughts were interrupted.

As he walked through the crowd, Academician Yuan grabbed him by the shoulder and asked eagerly.

"What about Professor Lu? Where is he now? "

Looking at Academician Yuan anxiously, Yang Xu was slightly shocked and said.

"Professor Lu It's back. "

After Academician Yuan, director Zhang hurriedly asked.

"Where are you going?"

"Back to the hotel, of course..."

Where else can I go? Can I go back to Jinling?

Yang Xu looked at the two relieved people strangely, not knowing what they were worried about.

Determined to calm down, Academician Yuan looked at the assistant behind him and said.

"Get the car ready now. We'll go to the hotel now."

Hearing that Academician Yuan was going to leave, director Zhang asked quickly, "what about the experiment?"

Academician Yuan went on for a while.

"Twenty four hours first."

Although he knew it in his mind, the experiment had already begun, and the process was still in good condition.

The next experimental arrangement was explained. Academician Yuan did not stop, and walked out of the factory with deputy general Zheng, who was closely behind him.

……

Mathematics is the language of the creator.

The question of mathematics is the riddle left by the creator.

Many things don't have to be seen with your own eyes. In many cases, pure numbers are more intuitive than what you see.

As for the seemingly irregular temperature time function

In the eyes of others, it may be inconceivable to solve it, but for him, it is not even a challenge.

After leaving the space city, Wang Peng sat in a happy boat with the white crowd borrowed from the local Guoan and asked him to drive directly back to the hotel.

Through the rearview mirror, I noticed that the expression on Lu Zhou's face was very pleasant. Wang Peng asked with a smile.

"What good has happened?"

"That's right," said Lu Zhou in a relaxed voice. "After solving this problem, the Moon Palace will finally be able to go on the road safely."

Wang Peng didn't ask how it was solved. After all, he knew that he couldn't understand even if he asked.

Looking out of the window, he asked.

"And Professor Yang?"

Lu Zhou smiled and waved his hand: "don't wait for him. He doesn't believe me. He has to wait there to see the result. Later, he can go back in the car of the aviation science and technology group."

Wang Peng: "you bet with him again?"

The boat gave him an unexpected look.

"How did you know that?"

"Guess it all!"

Wang Peng smiled and shook his head, started the car, drove on the road, followed the navigation to the direction of the hotel

……

When he arrived at the hotel, Lu Zhou went back to his room and packed his luggage. He called his assistant Zhao Huan and asked her to help him and Yang Xu book two return high-speed rail tickets.

After hanging up, it was almost time for dinner, so I went downstairs to the cafeteria on the first floor.

When the elevator door opened, just when the boat arrived at the lobby on the first floor, there was a series of dense footsteps in the direction of the door.

Lu Zhou looked up and saw Academician Yuan coming in with a large group of people.

Including Yang Xu, who had not come back with him before, academician Yang Zhongquan, who came from Shen Ji, and vice president Zheng, who is in charge of the space station project.

Only when director Zhang was not in, I think he was still in the lab.

Lu zhouzheng was going to say hello to old Mr. Yuan. But he saw that Academician Yuan had already come to him quickly. He began to talk quickly without saying a word."What did you do in it?"

Lu Zhou: "it doesn't work to answer me first."

"It works!" Academician Yuan nodded his head hard and said excitedly, "it's not for ordinary dropper!"

Lu Zhou smiled and said, "in fact, it's not a mystery. It's to improve the affinity of n-1 carbon nanotubes on the interface of aluminum copper alloy by copper plating, and then cold weld the material to the contact position between the heating part and the capillary structure of the loop heat pipe. The problem is basically solved..."

Simply speaking, it is equivalent to coating several parts with high heat generation in the core cabin with "heat dissipation silica gel", which improves the heat exchange rate between the heating parts and the capillary structure of the loop heat pipe, and enables the radiator as the "fan" to radiate the excess heat more efficiently.

Of course, it's just an inappropriate metaphor. After all, the way of heat dissipation of spacecraft and electronic components is quite different.

Academician Yuan is going to ask something else, but this time, academician Yang Zhongquan is the first to ask.

"Your n-1 material is very interesting Is it copper plated carbon nanotubes? "

Lu Zhou: "in short, it's like this."

"What about the thermal conductivity?"

"About 2000 W / (m · K)."

In fact, this figure can be improved. However, the length of the N-1 carbon nanotubes produced by the current laboratory preparation method is quite unstable, the short can reach μ m level, and the long can reach mm level, which is difficult to control.

However, even if so, the thermal conductivity of 2000 W / (m · K) is quite terrible.

After hearing the number of 2000, Yang Zhongquan took a cold breath and looked at Lu Zhou with unbelievable eyes. His tone was full of disbelief.

"Your material is a little scary, 2000 W / (m · K) This has to be several times that of pure copper! "

Among the common metals, silver has the best thermal conductivity, but its price is too expensive to use. The thermal conductivity of copper is the second, but it is too heavy. Generally, it is made of aluminum copper alloy, which is the common material of loop heat pipe in spacecraft.

At present, the relatively good high thermal conductivity graphite film, which is about 10-20 m m thick, can only achieve 1400 w / (m · K) in-plane thermal conductivity. However, even if so, it has made the major mobile phone manufacturers high and trendy.

2000W / (m · K) thermal conductive powder

The thermal conductivity NIMA is almost catching up with the diamond!

Not to mention electronic equipment manufacturers, even the industry has to follow Gao Chao

Lu Zhou didn't know much about the market of heat conducting materials in the industry, so hearing Yang Zhongquan's lament, he just laughed back.

"Is that ok? It works. "

Looking at Lu Zhou with a little embarrassment, Yang Zhongquan hesitated for a while, and finally seemed to have made up his mind. He reached out and touched the back of his head. He said with a smile.

"By the way, your n-1 carbon nanotube powder How do you sell it? Is it expensive? "

The boat gave him an unexpected look.

"Are you interested, too?"

Yang Zhongquan couldn't help saying: "nonsense, you don't know what high thermal conductivity material means in the industrial field! Take the linear grating ruler that we are recently engaged in high-precision industrial machine tools. The thermal expansion problem directly affects the accuracy of the side collimation! The final problem will be presented on the workpiece in the form of error! "

Although I don't know very much about the specific production problems, seeing academician Yang Zhongquan's spitting stars flying, Lu Zhou can probably guess that the heat dissipation function of n-1 carbon nano materials is not small in the industrial field.

It's amazing.

Originally, his orientation of n-1 material was a plastic material with high tensile strength, but he didn't expect that because he couldn't prepare complete and long small aperture carbon nanotubes, it finally made it shine in the field of heat dissipation.

Quietly waiting for the old man to finish, Lu Zhou coughed softly.

"Let's talk later about whether it's expensive or not. Now this material is still in the experimental stage. It's not such a big problem in the core cabin. I didn't plan to take it out. Wait for mass production to solve Let's talk about the price. "

Academician Yang Zhongquan said with a quick smile: "Cheng! Then I'll wait for you! Come on! "

Originally, I came here to repay the human feelings, but I didn't expect to have the harvest.

Just to hear the good news, he will not lose a trip here from Fengtian!

There was no chance to speak. Seeing that academician Yang Zhongquan finally stopped talking, vice president Zheng hurriedly asked, "Professor Lu! I have another thing to ask you. You've welded all the parts in the core cabin. What will you do when you dismantle them? "

On hearing this question, Lu Zhou immediately laughed and asked a funny question.

"Are you going to go up and dismantle it?"

Zheng Xiangdong was stunned and didn't react at first.He didn't realize something until he noticed yuan's disdainful eyes. Then he smiled and stopped talking.

Indeed, spacecraft are sent to the sky, unless the service life is reached and actively abandoned, who will run up to dismantle the installed parts.

Even if it's for maintenance, it doesn't come with such repai
