Steam Daming: Stop calling me to supervise the country

Chapter 58 Radiators

After Hu Shanwei left from Zhu Zhanchang's yard, he felt flushed and hot on the road, and his heartbeat was very fast.

The impact of Sun Ruowei's incident in the palace is still quite big, even if the Crown Princess finally suppressed it, but because Hu Shanwei didn't deliberately conceal it, there were many people present who knew about it.

Youyou couldn't hold back, this experience of Sun Ruowei will become the concubine Hu Shanxiang, who will make her lower forever in the future.

Of course, if the last history is the same, Zhu Zhanji will abolish Hu Shanxiang and establish Sun Ruowei as the queen, who knows the story here, whether it is right or wrong.

The matter passed quickly, and no one mentioned Sun Ruowei again the next day, but in the future, this story will be passed on by word of mouth, and it will even become more and more outrageous.

Every mouth that is good at talking behind people's backs is an excellent fantasy novelist.

……

Two days later, it was time for Zhu Zhanchang to go to Zheng He's mansion. This time, Li Xiaozhu didn't come, so why not spend half a day with Li Xianyu?
As soon as he arrived at the door of Zheng He's house, he saw an unexpected person. The middle-aged and slightly fat man was Zhao Quan, the shopkeeper of the Jiang family's bank.

Zhao Quan was waiting at the door of Zheng He's mansion. He knew from Prince Zhao that Zhu Zhanchang would come to Zheng He's mansion every once in a while. Zheng He was also a client of Jiang's bank, so the two still knew each other.

It's just that Zheng He didn't know whether Zhu Zhanchang knew Zhao Quan. After Zhao Quan explained it himself, Zheng He allowed him to wait for Zhu Zhanchang on the periphery. If Zhu Zhanchang allowed him, he would enter the mansion together.

When Zhao Quan saw Zhu Zhanchang, he hurriedly stepped forward to salute. He came to confess his eldest brother, so he should not be lower.

"His Royal Highness, more than ten days have passed since the day we left, but I still remember Caomin."

"Manager Zhao, why are you here?"

"Caomin specially came to these Highnesses, and talked with His Royal Highness that day, and he was stunned, and after returning, Caomin compiled what he saw and heard in his life into this book [The Fundamental Circulation Strategy of Money and Silver] I want to dedicate it to Your Highness, and I hope His Highness will take a look at it. ."

Zhu Zhanchang took the book and flipped through it. The first item in his head was gold and silver holdings. At a rough glance, Zhao Quan meant that no matter how many grain coupons the country issued, gold and silver should still be put in the stock. You can even take the opportunity of food stamps to collect gold and silver from the private sector into the state treasury.

Looking back at it later, it is some of the knowledge and skills of saving and lending that he has summed up.

It is impossible for an ordinary businessman to write such a thing, and even if it is written, it will only be left to his son to read. This is his experience and the skill he relies on to survive.

It's just that now Zhao Quan has to show his sincerity in order to propose himself.

After seeing it, Zhu Zhanchang was quite satisfied, so he said, "Come in with me, and I'll talk to you in detail when the things on my side are completed."

"Yes, yes." Zhao looked happy.

He did not show his sophistication and calmness in front of the child Zhu Zhanchang, but nodded and bowed like a servant servant, humble enough to express his loyalty to Zhu Zhanchang.

Taking him to the steam engine workshop, Zhao Quanyi was stunned when he saw these novelties. No one explained that he had no idea what the steam engine was used for.

I can't understand it either.

Until he saw the steamboat driving on the water, he seemed to have opened the door to a new world, he had greater confidence in the bank, and his trust in Zhu Zhanchang made him subtly believe that Zhu Zhanchang can do anything.

He understands that the world is changing rapidly, and he can't wait to find ways to get on the giant ship of this era.

Zheng He said the current problem of the steam engine: "Your Highness, recently we tested the steam engine, and it started running fine, but after a quarter of an hour, the steam engine will be very hot and become very dangerous."

Both high temperature and high pressure are dangerous.

At this stage, the steam engine has reached Zhu Zhanchang's knowledge blind spot. He only knows that the internal combustion engine has a radiator.

The air is cold and the cold water is cold. As an excellent auto mechanic, Zhu Zhanchang has not changed the water tank from 100 to 80 in a year, and there are countless water pipes.

But all he knows are the cooling systems of internal combustion engines. He is very familiar with the cooling systems of several commonly used models, but he does not know whether the cooling systems of internal combustion engines can be used in steam engines.

Do steam engines need heat dissipation?He really doesn't know this, because all of them are internal combustion engines.

The principle of internal combustion engine heat dissipation is actually very simple, water cooling, wind cooling, water pipe connected to the engine, which contains antifreeze, which is accurately called antifreeze coolant. The high temperature liquid flows from the water pipe into the auxiliary kettle and then enters the water tank for air cooling. heat sink.

The radiator is made of dense metal sheets to increase the contact area with the air, and the cooling liquid is cooled during driving and then flows back into the water pipe to cool the engine.

Air-cooled, liquid-cooled machines.

This allows the engine to stabilize the temperature within an operating range for a long time.

The cooling liquid needs to have the characteristics of not easy to evaporate, not easy to boil, and not easy to solidify. Now he can't make cooling liquid, and his chemical knowledge is relatively lacking, so he can only replace it with water.

Zhu Zhanchang had to work with the craftsmen to find a way to create a pipeline through which liquid can flow in the iron body of the steam engine, and add water to it from time to time for cooling.

However, because the boiling point of water is low, high pressure is dangerous, but if the water is boiled, the temperature should theoretically be bearable. It may be more necessary to make a better decompression device than a radiator.

Both possibilities have to be tried. The radiator and the pressure reducing valve are two ways, and see which way works.

The development of the steam engine to this stage can no longer be perfected by relying on principles. It takes step-by-step trial and error to find the correct route.

This task fell to Zhang San and others again, but Zhang San and others were full of energy. As long as Zhu Zhanchang ordered them, they would do everything they could.

Since Zheng He taught them Zhu Zhanchang's power of the operation of all things, these people admire Zhu Zhanchang even more, and now they spend at least half an hour every day to learn and share the knowledge of the operation of all things.

This is a person who is good at practice, and after several practice, he recognizes the knowledge in the book very much.

Now in their eyes, what Zhu Zhanchang said is what.

After adjusting the details, Zhu Zhanchang discovered that although the principle of the steam engine is simple, it is not a problem for people like him to create one, but it is still a huge and long-term project to build a steam engine that can meet the long-term use. .

It needs the cooperation of various industries. According to their progress, it may be possible to build the first steam engine that can run and be used within the predetermined time, but it will be completed before the end of the year at the earliest.

Seeing that Zhu Zhanchang's affair was over, Zhao Quan interjected, "His Royal Highness, this steam engine is so ingenious that even a god would not dare to imagine a world without horses."

"Oh yes, I almost forgot about you. What you wrote is good. I will discuss it with my eldest brother. If my eldest brother allows it, I will use you. Go home and wait for news." Zhu Zhanchang was like a HR who sends people home to wait for news.

Taking Zhao Quan to see the steam engine is to let him see his own strength.

Zhao Quan bowed excitedly and said respectfully, "Caomin Zhao Quan is willing to serve His Highness."

Zhu Zhanchang asked him to go home first, and someone would tell him after the matter was decided.

After sending him away, Zhu Zhanchang finally had time to meet his princess in distress.

Zheng He walked away wisely, and Zhu Zhanchang walked to Li Xianyu's small courtyard alone.

Pushing the door and entering, Li Xianyu was sitting in the small yard. There was a swing here. The lovely girl was sitting on the swing and rocking gently, welcoming him with a bright smile.

He likes such a girl, and her love does not need to be guessed.

　Economic foundation, agricultural foundation, these are the basic factors for Yang Fan's voyage.

　　Because the production of a steam engine is a long process that requires continuous trial and error, the process of trial and error will be very long if I keep writing, so in the process of continuous improvement by the craftsmen, the improvement process of the protagonist in some key links will be interspersed. At the same time, it is constantly changing the economic foundation of Ming Dynasty, and then there is the agricultural foundation.

　　As for the supporting actresses, each supporting actress has a completely different character, such as the black-bellied and talented Hu Shanwei, the arrogant and world-weary Li Xiaozhu, and the submissive Li Xianyu.
