Chapter 757 Terrifying Heat Dissipation Material

On the other side, looking at the excited, cheering and embracing engineers, looking at the temperature-time function curve with no regularity, Yang Xu slowly opened his mouth and then closed it again.

Is this the strength of the Fields Medal winner?

No wonder the Nobel Prize Committee was overwhelmed by his ability...

It's no wonder that the entire computational materials science community is crazy about his theory...

Once upon a time, Yang Xu believed that he was very close to the Nobel Prize, especially after he won the "Citation Laureate Award", which is known as the vane of the Nobel Prize, for his lithium-sulfur battery cathode material and SG-1 superconducting material. I firmly believe this.

The reason why the Nobel Prize Committee did not consider him was mainly because the name of the collaborator of the thesis was too dazzling. Sooner or later, he would be able to produce his own results and complete qualitative changes through quantitative accumulation!

But now, he felt a deep sense of powerlessness.

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

Those who can win the Nobel Prize are all monsters...

Sure enough, I'm still far behind...

At this moment, his drifting thoughts were interrupted.

Walking through the crowd, Academician Yuan grabbed his shoulder and asked eagerly.

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

Looking at Academician Yuan with an eager face, Yang Xu froze for a moment, and said.

"Professor Lu...has already gone back."

Director Zhang, who was following Academician Yuan, hurriedly asked.

"Where did you go?"

"Of course it's back to the hotel..."

Otherwise, where else can I go? Is it possible to return to Jinling?

Yang Xu looked at the two people who were relieved with a strange expression, not quite understanding what they were worried about.

Gathering his mind, Academician Yuan looked at the assistant who was following him, and said.

"Get the car ready right away, we're going to the hotel now."

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

Academician Yuan pondered for a while and continued.

"Let's finish it for twenty-four hours first."

Although he already knew it in his heart, the experiment had already started, and the process was still completed.

After explaining the next experimental arrangement, Academician Yuan didn't stop, and walked out of the factory with Vice President Zheng following closely behind.

...

Mathematics is the language of the Creator.

Questions about mathematics are riddles left by the Creator.

Many things don't necessarily have to be seen with one's 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 seem incredible to solve it, but for him, it is not even a challenge.

After leaving Aerospace City, Lu Zhou was in a good mood and got into the white Volkswagen that Wang Peng borrowed from the local Guoan, and asked him to drive back to the hotel directly.

After noticing the joyful expression on Lu Zhou's face through the rearview mirror, Wang Peng asked with a smile.

"Did something good happen?"

"Forget it," Lu Zhou said with a relaxed tone, "After solving this problem, the Moon Palace can finally go on the road safely."

Wang Peng didn't ask how to solve it, after all, he knew that even if he asked, he probably wouldn't understand.

Glancing out of the car window, he asked.

"Where's Professor Yang?"

Lu Zhou smiled and waved his hands: "Don't wait for him, he doesn't believe me, he insists on waiting there to see the result, after a while he can take the car from Hangke Group to go back."

Wang Peng: "Did you bet with him again?"

Lu Zhou glanced at him unexpectedly.

"How did you know that?"

"Guess everything!"

Wang Peng smiled and shook his head, started the car, drove on the road, and drove towards the hotel according to the navigation...

...

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 book two return high-speed rail tickets for himself and Yang Xu.

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

The elevator door opened, and just as Lu Zhou arrived at the lobby on the first floor, a series of dense footsteps came from the direction of the door.

Lu Zhou looked up, just in time to see Academician Yuan walking in with a large group of people.

Including, Yang Xu who didn't come back with him before, Academician Yang Zhongquan from Shenji, and Vice President Zheng, the person in charge of the space station project, were all inside.

The only thing was that Director Zhang wasn't there at that time, and probably he was still in the laboratory.

Seeing the people coming and smiling, Lu Zhou was about to go up to say hello to Mr. Yuan and the others, but saw that Academician Yuan had already walked in front of him, and hurriedly said without saying hello.

"What the hell did you do in there?"

Lu Zhou: "Answer me first whether it will work or not."

"It works!" Academician Yuan nodded vigorously, and said excitedly, "It's not for ordinary droppers!"

Lu Zhou smiled and said, "Actually, it's not a mysterious thing. It is through copper-plating N-1 carbon nanotubes to improve their affinity on the aluminum-copper alloy interface, and then cold-weld the material until it heats up. At the point of contact between the component and the capillary structure of the loop heat pipe, the problem is basically solved..."

To put it simply, it is equivalent to coating several parts with high heat generation in the core cabin with a layer of "radiation silica gel", which improves the heat exchange rate between the heat-generating parts and the capillary structure of the loop heat pipe, and makes the heat sink as a "fan" Excess heat can be radiated more efficiently.

Of course, this is just an inappropriate metaphor. After all, the heat dissipation of spacecraft and the heat dissipation of electronic components are still very different in the way.

Academician Yuan planned to ask something else, but this time Academician Yang Zhongquan spoke first.

"Your N-1 material is quite interesting...Is it copper-plated carbon nanotubes?"

Lu Zhou: "Simply put, it's like this."

"What about the thermal conductivity?"

"About 2000w/(m·k) or so."

In fact, this number can still be improved, but with the current laboratory preparation method, the length of the N-1 carbon nanotube material produced is quite unstable, the short one can reach the μm level, and the long one can have the mm level. hard to control.

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

After hearing the number 2000, Yang Zhongquan gasped, looked at Lu Zhou with unbelievable eyes, and said in an unbelievable tone.

"Your material is a bit scary, 2000w/(m·k)... This must be 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 highest thermal conductivity, but it 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 kind with a thickness of about 10-20mm, can only achieve 1400w/(m·k) in-plane thermal conductivity. However, even if this is the case, it has already made the major mobile phone manufacturers climax.

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

In terms of thermal conductivity, Nima is almost catching up with diamonds!

Not to mention electronic equipment manufacturers, even the industry may have to follow suit...

Lu Zhou didn't know much about the market of thermally conductive materials in the industry, so when he heard Yang Zhongquan's emotion, he just laughed and replied.

"Is it okay? Anyway, it works."

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

"By the way, your N-1 carbon nanotube powder...how did you sell it? Is it expensive?"

Lu Zhou glanced at him unexpectedly.

"Are you interested too?"

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 lateral alignment! Ultimately, the problem will Presented on the workpiece in the form of errors!"

Although he doesn't know the specific production issues very well, but seeing Academician Yang Zhongquan spitting stars and flying across the sky, Lu Zhou can probably guess that the heat dissipation function of N-1 carbon nanomaterials may have a lot of uses in the industrial field.

It's really amazing.

He originally positioned the N-1 material as a plastic material with high tensile strength, but he did not expect that because he could not prepare complete and long small-aperture carbon nanotubes, he finally made it shine in the field of heat dissipation .

Waiting quietly for the old man to finish speaking, Lu Zhou coughed lightly and said.

"I'll talk about whether it's expensive or not. This material is still in the experimental stage. It's not that there is such a big problem in the core cabin. I don't plan to take it out. Wait until the method of mass production is solved... Let's talk about the price Bar."

Academician Yang Zhongquan hurriedly said with a smile: "Success! Then I will wait for your good news! Come on!"

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

Just to hear the good news, it's not a loss for him to make a special trip here from Fengtian!

Seeing that Academician Yang Zhongquan finally stopped talking, Vice President Zheng hurriedly stepped forward and asked, "Professor Lu! I have another question to ask you. Solder all the components in the core cabin. If it is dead, what should we do if we have to dismantle it then?"

Upon hearing this question, Lu Zhou suddenly smiled and asked jokingly.

"Are you planning to go up and tear it down?"

Zheng Xiangdong was stunned for a moment, but didn't react at first.

It wasn't until he noticed Academician Yuan's disgusted eyes that he realized something, and then he smiled mischievously and stopped talking.

Indeed, the spacecraft have all been sent to the sky, unless they are voluntarily discarded when they reach the end of their useful life, who will run up and dismantle the assembled parts without any problems.

Even if it's an overhaul, it doesn't need to be repaired like this...
