Video spoilers history, starting with the blitzkrieg on Poland

The sky continues.

[Although the thermos is not an absolute vacuum. 】

【But even so, heat cannot be transferred. 】

[It can also achieve a very good heat preservation effect, sometimes even maintaining the temperature for several days without getting cold. ]

[The same is true for the space station.]

[The space station is in a vacuum of even higher purity.]

[The heat emitted by various machines in the space station can hardly be dissipated through heat transfer.]

[So, how does the space station dissipate heat in this cold universe? ]

[In fact, the space station mainly relies on two methods to dissipate heat. ]

[One is radiation heat dissipation, and the other is liquid circulation heat dissipation. ]

【Let’s talk about radiation heat dissipation first. 】

[A large area of ​​heat radiators is installed on the outer surface of the space station. ]

[These thermal radiators are like the "cooling wings" of the space station, and their role is very critical. ]

[When the equipment inside the space station generates heat, the thermal radiator will radiate this heat into space in the form of infrared rays.]

[It is just like the thermos cup we use in daily life. The thermos cup has a vacuum insulation layer, which can reduce the heat loss through conduction and convection. ]

[But a small amount of heat will still be slowly dissipated in the form of radiation. ]

[The space station's thermal radiators use a similar principle.]

[It just actively transfers heat to space in the form of infrared radiation.]

[Because infrared rays are electromagnetic waves that can propagate in a vacuum, heat can be smoothly transferred from the space station to outer space.]

[In addition to radiant heat dissipation, the liquid circulation system also plays an important role. ]

[Inside the space station, there is a set of carefully designed liquid circulation pipelines. ]

[A special liquid circulates continuously in these pipes, acting like a hardworking "heat transporter."]

[When liquid flows through a heat-generating device, it absorbs the heat emitted by the device.]

[Then carry this heat to the thermal radiator]

[At the radiator, the liquid transfers the absorbed heat to the radiator, and then continues to circulate to absorb new heat. ]

【Friends who are familiar with computers will definitely see this. 】

[The same is true for computer radiator copper tubes! ]

[Just like the liquid circulation system of the space station, the heat generated by the equipment is transferred to the thermal radiator and then dissipated into space. ]

【Through this cycle. 】

[The heat inside the space station is continuously transferred to space.]

[This ensures that the temperature of the space station is always within a suitable range.]

The sky screen video ended here, and barrages of comments flew out one after another.

《In fact, the heat conduction mainly depends on the radiation in the vacuum environment, which requires a medium.》

《Thermal knowledge: The principle of thermos bottle is vacuum insulation.》

《There are only three ways to dissipate heat: heat conduction, heat convection, and heat radiation.》

"The space environment has no heat conduction and convection, so it can only dissipate heat through radiation, which is definitely inefficient."

《You will understand after playing Oxygen Not Included.》

"No wonder all those sci-fi works show that space battleships have huge heat sinks."

"Can the temperature control ability in the novel be restrained to a certain extent by using vacuum isolation?"

The ancients also learned some new knowledge.

Not only did we know that the universe is extremely cold.

This was speculated by the ancients before.

I also learned that spacecraft in the universe need to pay attention to heat dissipation.

In this regard, Sima Zhong expressed his opinion:

"It seems that the universe is indeed very strange, but also very warm."

"If winter is too cold, send me to the sky."

"Wouldn't that be warm?"

"I want to travel in outer space?"

Sima Zhong's words left all the ministers speechless.

But they were used to it. The people of the Jin Dynasty pretended not to hear it.

Continue looking at the sky.

And the new sky screen will be released soon!

A familiar map of China appeared on the sky.

The camera also continued to focus, focusing on the Yangtze River Basin.

The commentary also slowly sounded.

[If you were to choose an MVP among all the rivers in the world, where would the Yangtze River rank? ]

【What if I tell you that the Yangtze River is not the longest river in the world. 】

[Although the Yangtze River is not the deepest river in the world. ]

[Although the Yangtze River is not the river with the most water in the world. ]

[But if we were to comprehensively select the MVP of a river, the Yangtze River would undoubtedly be the global GOAT. ]

[The Nile River, the Amazon River, and the other large rivers in the United States, Russia, and India that we are familiar with are not as good as the Yangtze River.]

……

Tianmu made a very arbitrary conclusion right from the start.

When the ancients saw this conclusion, they naturally thought it was natural.

Qin Dynasty.

Ying Zheng smiled slightly and said:

"Why, the best river in the world is not the Yellow River, but the Yangtze River?"

“Why do I feel that the Yellow River is more important than the Yangtze River?”

"But it doesn't matter. They are all rivers owned by our Great Qin anyway. And it can be seen that the Yangtze River is indeed longer and has a richer water system."

"Plus, Tianmu said before that in the future the south will be even more densely populated and economically developed than the north."

“This shows that if the Yangtze River develops, it may indeed be more powerful than the Yellow River.”

Late Han Dynasty.

At this time, Liu Bei was on the bank of the Yangtze River, looking at the rolling waters of the Yangtze River.

I couldn't help but say:
"Fight for supremacy in the Central Plains and conquer the world!"

"In my time, if we want to revive the Han Dynasty, we have to recover the Yellow River Basin."

“But look at the view of the Yangtze River in front of you.”

“Think about the people living on both sides of the Yangtze River.”

"Thinking about the prosperity of Jingzhou and the wealth of Jiangdong, I can only say that Tianmu is definitely not talking nonsense."

During the Qin and Han dynasties, the economic focus was on the Yellow River Basin.

Ancient people were able to understand that the Yangtze River is the best river in the world.

Not to mention later dynasties such as the Eastern Jin, Southern Song, and Ming dynasties, where the economic center gradually moved southward.

The ancient people of these dynasties.

Naturally, it is more understandable and convincing.

my country's Yangtze River is the MVP among the world's rivers.

Not only the domestic MVP.

Even compared with rivers in other countries, it is the best river.

This is a kind of confidence.

However, the ancient people had confidence in China.

On the contrary, many modern netizens lack it.

For example, at this moment, many comments raised doubts on the screen.

"How can the Yangtze River be stronger than the Nile River? The Nile River is much longer than the Yangtze River."

"Compared to the Amazon River, the Yangtze River is just a little brother."

"The Rhine flows through the most developed region in Europe, which is much stronger than the Yangtze River, where at least half of the area along the way is the underdeveloped central and western regions."

"Do you know how valuable the Mississippi River in the United States is?"

《Feeling exaggerated, right?》

《Win again, right?》

"I think this is a kind of confidence." (End of this chapter)
