Chapter 772

It's so quiet that Zhuang Jianye's "sorry, don't sell" is like a stop sign between heaven and earth, so that the noise of the rumbling equipment around is replaced by the sharp sound.

There's no way. Many of the people present were shocked by Zhuang Jianye's statement. As for the brain failure, there are countless, especially the local provincial leaders and senior managers of factoring group.

Listen to Zhuang Jianye's words, almost a brain infarction, a heart infarction directly in the past, 5 billion dollars, so to refuse, it's a real death!

That's all right. What do you mean by Zhuang Jianye's arrogance? The US $5 billion is not worthy of Tengfei group.

It's just a small set of metal parts. What's rare? If you don't sell it, you can't even sell it. Believe it or not.

Just when the two leaders were ready to use their high pressure to force Zhuang Jianye, a young man, blindly, merlinz's next attitude surprised the two leaders.

After listening to Zhuang Jianye's words, merlinz's fat face was slightly embarrassed, but he soon returned to normal. However, the convex saddle in his hand was squeezed more tightly, for fear that he would lose something in his hand at the next moment.

At the same time, a flattering smile appeared on his face and nodded: "what Mr. Zhuang said is that this kind of epoch-making space technology can not be measured by money. This is the international practice. It's my rashness, it's my rashness."

As soon as this remark came out, both the local provincial leaders and the senior executives of factoring group were stunned by merlinz's words. How could that humble metal part be an epoch-making aviation technology?

What's going on?

Why didn't you see it?

Where is the era?

Of course, this is not the most important thing. The key is the attitude of merlinz, who is an American with advanced technology and self-confidence.

No matter where you go, you are superior. No matter what kind of high technology you see, you are surprised, just like you saw DL series aerospace special processing equipment just now.

Shocked, surprised, and then? In addition to affirming the technical strength of Tengfei group, there is no next step.

Why?

It's not that Americans have mastered the so-called super life vibration processing technology for a long time. Now that they have it, it's not surprising. The reason why they are shocked is that they underestimate China and Tengfei group, and then they have high psychological expectations.

In essence, there is no substantial change.

At this moment, however, it's different. Like a third grandson, merlinz apologizes to Zhuang Jianye with a flattering face, just for the convex saddle piece the size of a small arm.

It's hard not to shock people. Is this still an American with eyes above the top?

Of course, what is more important is that local provincial leaders and senior managers of factoring group are aware of a key problem, that is, the convex saddle which is not so different from the sewer pipe at home is by no means simple.

So the senior manager of factoring group took advantage of Zhuang Jianye's conversation with merlinz and asked Lin Guanghua who accompanied him: "what's the situation with that thing?"

Lin Guanghua smile, close to factoring Group executives ear said: "Americans can't do it!"

Hearing this, the senior executives of factoring group immediately opened their eyes and almost blurted out something that Americans can't do in the world.

Fortunately, Lin Guanghua quickly explained the details, which made the senior management of factoring group have no gaffe.

It turns out that merlinz is right. The convex saddle workpiece produced by Tengfei group is indeed a modern aerospace technology.

The scientific name of this technology is loop heat pipe technology. The main function of this technology is to heat the key systems of satellites, lunar probes, Mars probes and even manned spacecraft, space shuttle and other outer space spacecraft.

We should know that the equipment carried by the spacecraft in outer space, like the similar equipment on earth, will produce a lot of heat when working.

This problem is not difficult to solve on earth, air cooling, water cooling, working fluid cooling, all kinds of cooling, there is always a way to make your equipment not hot fever.

However, this kind of thing is not a problem on earth, but a big problem on space spacecraft.

You know, the outer space environment does not have the buff of the earth's atmosphere. When it's cold, it's suspicious of life. When it's hot, it can melt metal.

That's all. What's more important is that the transition between hot and cold is very fast. In an hour or two, it's possible to walk back and forth between extremely cold and super hot. It's a real ice and fire day.

The problem is that there is nothing wrong with cold. The components and systems on the spacecraft need to dissipate heat when they are working. Cold is not a bad thing, but the heat enough to melt the metal can't stand it. Originally, the spacecraft will generate a lot of heat when it is working. Adding a fire to the outside will immediately push the spacecraft to hell.

Because of this, we need a kind of light, efficient, less impact on the spacecraft cooling system to escort the spacecraft.Otherwise, the equipment inside the spacecraft, which has been built at a high price and launched by launch vehicles, will be burnt out as soon as it is launched into the sky. In the end, an empty shell will be left, which is even worse than floating. The problem is that the cost of the aerospace field is tens of millions of dollars. Even if the local tyrants like to float, they will be bankrupt within a few times.

But it's not difficult to make such a cooling system. Only the United States and the Soviet Union (Russia) have this ability in the world.

The others are brothers.

Among them, the Americans are very local tyrants. They use the power or energy carried by the satellite to drive a working fluid that liquefies when it is cold and gasifies when it is hot. They use the conversion of gasification and liquefaction to efficiently heat the spacecraft system.

The actual effect is not bad, which has become the mainstream spacecraft cooling technology since the 1960s.

The problem is that the U.S. can't keep up with other countries, because the power consumption of this kind of cooling system is very high, ordinary solar cells are not enough, and even strengthening the fuel carried by satellites can't last long.

Of course, Americans know these disadvantages, so they install more powerful and theoretically wireless output nuclear batteries on satellites to solve the problem of power consumption of cooling system.

When it comes to nuclear power, no one can be sure of the miniaturization of nuclear batteries. Even the Soviet Union can not maintain long-term stability in terms of nuclear batteries.

Because of this, the Soviet Union gradually lagged behind in the space competition and was about to be crushed by the Americans in the space field. The Soviet Union finally launched a fierce campaign. Since the stability of nuclear batteries could not match that of the United States, it would not be necessary to use this method of energy consumption to directly develop a heat dissipation system that could make the working fluid efficient and automatic circulation.

So loop heat pipe technology, an epoch-making product that subverts the era and breaks the monopoly, came into being in the hands of Soviet scientists.
