Scholar’s Advanced Technological System

On the other side, looking at the excited and cheering engineers hugging together, looking at the temperature-time function curve with no eggs, Yang Xu's mouth slowly opened and closed slowly.

Is this the strength of the Fields Prize winner?

No wonder the Nobel Committee will be convinced by his ability ...

No wonder the entire field of computational materials is going crazy for his theory ...

Once upon a time, Yang Xu believed that he was very close to the Nobel Prize, especially after winning the "Citation Laureate" called the Nobel Wind vane with the lithium-sulfur battery cathode material and SG-1 superconducting material. I firmly believe this.

The reason why the Nobel Committee did not consider him was mainly because the name of the thesis collaborator was too dazzling, and one day he could come up with his own achievements and complete the qualitative change through the accumulation of quantity!

But now, he felt a deep weakness.

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

Those who can win Nobel prizes are monsters ...

Sure enough, I have a long way to go ...

Just then, his thoughts were interrupted.

When I saw him walking through the crowd, Academician Yuan grabbed his shoulder and asked eagerly.

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

Looking at Academician Yuan with an eager look, Yang Xu froze slightly and said.

"Professor Lu ... has gone back."

Director Zhang asked quickly after Academician Yuan.

"Where did you go?"

"Of course back to the hotel ..."

Otherwise, where else can we go?

Yang Xu looked at the two men who were relieved with strange expressions, and didn't quite understand what they were worried about.

After being settled, Academician Yuan looked at the assistant behind him and said.

"Get ready for the car right now, and we'll go to the hotel now."

Upon hearing that Academician Yuan was going to leave, Director Zhang quickly asked: "What about the experiment?"

Academician Yuan groaned for a while and continued.

"Take 24 hours first."

Although he already knew it, the experiments had already begun, and the process was still intact.

Explaining the next experimental arrangement, Academician Yuan was not staying, and led Vice President Zheng, who was closely following him, and walked out of the factory building.

...

Mathematics is the language of the Creator.

The question about mathematics is a riddle left by the creator.

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

As for the seemingly irregular temperature-time function ...

It may seem strange to solve it in the eyes of others, but for him, it is not even a challenge.

After leaving the aerospace city, Lu Zhou, in a good mood, boarded the white public borrowed by Wang Peng from the local Guoan and let him drive back directly to the hotel.

Looking through the rear view mirror, Lu Zhou's face was quite pleasant, and Wang Peng asked with a smile.

"Anything good happened?"

"That's right," Lu Zhou said in a relaxed tone. "With this matter resolved, Yue Gong could finally be on the road safely."

Wang Peng didn't ask how to solve it, after all, he knew that even if he asked most of them, he couldn't understand.

Looking out the window, he asked.

"Where is 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 results. He can go back in the car of Hangke Group later."

Wang Peng: "You bet with him again?"

Lu Zhou gave him an unexpected look.

"You don't know."

"Guess it!"

Wang Peng shook his head with a smile and started the car. After driving on the highway, he drove towards the hotel according to the navigation ...

...

At the hotel, Lu Zhou returned to the room to pack his luggage, called his assistant Zhao Huan, and asked her to book two high-speed rail tickets for herself and Yang Xu.

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

The elevator door opened. Just as Lu Zhou had just 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 that Academician Yuan came in with a large group of people.

Including, Yang Xu who had not returned with him before, Academician Yang Zhongquan from Shen Ji, and Vice President Zheng of the Space Station were all in it.

The only thing that happened was that Director Zhang was not there, and probably wanted to stay in the laboratory.

Seeing everyone smiling, Lu Zhou was about to step forward to say hello to Mr. Yuan Lao, but saw that Academician Yuan had walked to him in a hurry, and he hurried to speak without saying a word.

"What the **** did you do inside it?"

Lu Zhou: "The first answer is that it doesn't work."

"It works!" Academician Yuan nodded stubbornly, and said excitedly, "Not a general dropper!"

Lu Zhou smiled and said, "In fact, it is not a mystery. It is to increase the affinity of the N-1 carbon nanotubes by copper plating on the N-1 carbon nanotubes, and then cold-weld the material to heat. At the contact position between the component and the capillary structure of the loop heat pipe, the problem is basically solved ... "

In simple terms, it is equivalent to coating several components with high heat generation in the core compartment with a layer of "radiating silica gel", which improves the heat exchange rate between the heating component and the capillary structure of the loop heat pipe, and makes the "fan" heat sink. Ability to radiate excess heat more efficiently.

Of course, this is just an inappropriate metaphor. After all, the heat dissipation of spacecraft and the cooling of electronic components still have very different methods.

Academician Yuan intends to ask something, but this time it was Academician Yang Zhongquan who spoke first.

"Your N-1 material is interesting ... copper-coated carbon nanotubes?"

Lu Zhou: "Simply said."

"What about the thermal conductivity?"

"About 2000w / (m · k)."

In fact, this number can be increased, but with the current laboratory preparation method, the length of the produced N-1 carbon nanotube material is quite unstable, ranging from short to μm and long to mm. hard to control.

However, even so, the thermal conductivity of 2000w / (m · k) is quite scary.

After hearing the number 2000, Yang Zhong took a sigh of cold air, looked at Lu Zhou with an unbelievable look, and said in an unbelievable tone.

"This material is a bit scary, 2000w / (m · k) ... this is several times that of pure copper!"

Among the more common metals, silver has the best thermal conductivity, but it is too expensive and rarely used. Copper has the second lowest thermal conductivity, but is too heavy. It is generally made of aluminum-copper alloy with aluminum, which is a common material for loop heat pipes in spacecraft.

At present, the relatively good high thermal conductivity graphite film, the thickness of about 10-20mm, the in-plane thermal conductivity can only achieve 1400w / (m · k). However, even so, it has already made major mobile phone manufacturers climax.

2000w / (m · k) thermally conductive powder ...

Just to say that thermal conductivity Nima is almost catching up with diamonds!

Not to mention an electronic equipment manufacturer, even the industrial world is afraid to follow Gao Chao ...

Lu Zhou didn't know much about the market of heat-conducting materials in the industry, so when he heard Yang Zhongquan's emotion, he just laughed and answered.

"Are you okay? It will work anyway."

Looking at Lu Zhou with a little embarrassment, Yang Zhongquan hesitated for a while, and finally seemed to be determined. He reached out and touched the back of his head, and he asked with a smile.

"By the way, your N-1 carbon nanotube powder ... how is it sold? Is it expensive?"

Lu Zhou gave him an unexpected look.

"Are you interested?"

Yang Zhongquan couldn't help but said, "Nonsense, you don't know what high thermal conductivity materials mean in the industrial field! Take the linear encoders we have recently made on high-precision industrial machine tools. The problem of thermal expansion directly affects the accuracy of the alignment! The final problem will be In the form of errors on the workpiece! "

Although I don't know the specific production problems, but seeing the appearance of Academician Yang Zhongquan's spitting stars, Lu Zhou can still guess that the heat dissipation function of N-1 carbon nanomaterials is probably not small in the industrial field.

That's wonderful.

Originally, his positioning of the N-1 material was a high-tensile-strength plastic material, but he did not expect that because it was impossible to prepare a complete and long small-aperture carbon nanotube, it finally made it shine in the field of heat dissipation. .

Waiting quietly for the old gentleman to finish, Lu Zhou coughed softly.

"I will talk about this issue later. Now this material is still in the experimental stage. It is not such a big problem in the core compartment that I have no plans to take it out. When the mass production method is resolved ... we will discuss the price again. Right. "

Academician Yang Zhongquan smiled quickly and said, "Come! Then I'll wait for your good news! Come on!"

Originally, it was humane to come back, but I didn't expect to have this gain ~ www.readwn.com ~ He could only hear the good news. He made a special trip from Fengtian and it was not a loss!

I never had the opportunity to speak. Seeing that Academician Yang Zhongquan finally stopped his mouth, Vice President Zheng stepped forward and asked: "Professor Lu! I have to ask you one more thing. You weld all the components in the core compartment. Dead, what should I do then? "

Upon hearing this question, Lu Zhou grinned and asked jokingly.

"Are you going to dismantle?"

Zheng Xiangdong stunned, but didn't respond at first.

He didn't realize anything until he noticed Yuan Yuan's disgusting eyes, and then he smiled and stopped talking.

Indeed, the spacecraft has been sent to the sky, and unless they have reached the end of their useful life, no one will run up and disassemble the assembled components.

Even if it's overhaul, it's not like this ...
