Taking the only bi2te3 bismuth telluride in the world that has been industrially produced as an example, including the United States, before the doping mechanism was discovered, the thermoelectric conversion efficiency of bismuth telluride hovered between 2% and 3% depending on the processing technology. It is not that there is no application value, but the problem is that the application value is a waste of food and is a pity to abandon.

Take the m1a1 main battle tank currently equipped with the US Army as an example. Taking the skirts on both sides of the m1a2 track as the mounting components that constitute the temperature difference generator, if Liang Yuan’s shell replacement plan is put in, with the current technical level of semiconductor power generation in the United States, this shell-type temperature difference generator will not emit more than 25kw of power from the high-heat exhaust of the m1a1 main battle tank, and the construction cost will not be less than 1 million US dollars. As for the current purchase price of m1a1 tanks of less than 3 million US dollars, adding such a costly system to a battlefield consumption equipment is unless the men on Capitol Hill are crazy.

The technical basis that Liang Yuan, a shell-type temperature differential generator, relies on is the standard after the new century.

Take the only bismuth telluride that has been industrially produced as an example. The bismuth telluride processed through a new process based on the doping mechanism principle is no longer a simple bi2te3, but a structure mutated into bi2te2.85se0.15. After the elemental selenium is doped in, the advantages of bismuth telluride have been greatly improved. The thermoelectric efficiency originally hovered between 2% and 3% can be increased to 6% depending on the processing technology.

If it is replaced with the antimony silver magnesium series alloys discovered after the new century, the thermoelectric efficiency of the new materials processed using a new process will reach more than 8.5%.

If the temperature difference generator of the m1a1 main battle tank is designed according to the technical basis that Liang Yuan relies on, even if the traditional material new technology can be used, bi2te2.85se0.15 will be generated no less than 50kw. If the new material temperature difference generator is used after the new century, the power generation will be increased to an astonishing 80kw.

With the 1100kw engine power of m1a1, I dare not say I am not tempted when facing an increase in thermal efficiency of more than 7%. This is almost a rebuilding of an intercool and heat recovery system.

The intercooling and heating system of gas turbines is only between 7% and 12%.

Of course, super-large intercooling and rejuvenating systems like power plants or ships can increase the thermal efficiency of the power system by more than 15%. The problem is that tanks do not have such a large space for designers to waste.

After the first decade of the new century, the great development of thermoelectric materials attracted the attention of the US Army. The Army Laboratory and Ge had become interested in the exhaust gas utilization of m1a2, and early experiments also achieved good results. The problem is that after the first decade of the new century, the probability of large-scale armor duels between major powers is probably not much higher than that of throwing nuclear bombs with each other. The lack of demand from the US Army directly led to the various patch versions of m1a2 and had to continue fighting for 20 to 30 years. Let’s talk about the situation after 2030.

Although thermoelectric materials are embargoes abroad, Zhu Yusheng also has a rough understanding of the top standards of international thermoelectric materials because he has not broken through the situation for a long time.

After reading the complete document, Zhu Yusheng narrowed his eyes and followed Liang Yuan's thoughts and passed this plan in his mind.

In addition to the indicator of reducing radar reflection in appearance, Liang Yuan’s so-called stealth shell is also the installation location of semiconductor power generators. Through the overall design, this shell with a certain thickness can be regarded as an extra-large exhaust pipe of a tank engine. The engine’s high-temperature exhaust gas is discharged into the atmosphere after cooling and generating electricity through the exhaust flue composed of a temperature differential power generator.

Liang Yuan also made full use of the general energy gradient application standards of his mentor Wu Zhonghua's signature brand to utilize the high-temperature exhaust gas of the tank engine in segments, and used three types of semiconductor power generation sheets, high-temperature, medium-temperature and low-temperature, to cool down the engine's high-temperature exhaust gas.

According to the design of Liang Yuan, the temperature difference generator is mainly composed of the tank track skirt. Taking the Type 59 tanks equipped by the Republic as an example, if the skirt plate as a tank temperature difference generator is placed flat on the ground, and the exhaust passage of the tank waste heat adopts a dual-channel design on both upper and lower sides. The single-channel cooling mezzanine in the middle just cools the cold end of the temperature difference transmission plate. In this way, each skirt plate will get the actual layout area of ​​the temperature difference generator plate multiplied by two.

The width of the side skirt of the Wujiu Tank is between 0.6 and 0.7 meters, but the long skirt panel helps improve the protection level. Liang Yuan directly chose the value of 0.7 meters. The body length of the Wujiu Tank is 6 meters. According to Liang Yuan's design, the area used to install temperature difference power generators is about 16 square meters.

Of course, Liang Yuan is just for the sake of easy calculations. It doesn’t matter if the temperature difference power generation sheet is not arranged on the side skirt of the tank but on the vehicle body. The surface area of ​​16 square meters looks very large. As long as the stacking design is used, it may not be used even four square meters. As for how big it is, it depends on the designer’s thermal skills.

Most of the generation of tank infrared signals comes from high-temperature exhaust gas that cannot be effectively utilized by the engine. According to the law of conservation of energy, the more power generated by the temperature differential power generation device, the less energy that the tank cannot be utilized, that is, the less infrared signals leaked. This is to solve the problem from the root and is much more effective than a solution to reduce the tank exhaust temperature through a large amount of air heat exchange.

Through theoretical calculations, Liang Yuan took the Gem Stone Turboshaft engine as an example and took the Republic Type 59 tank as the modification basis. At the end of the document, he concluded that the high-temperature exhaust gas of the tank that has been fully processed through three-stage temperature differential power generation is finally discharged to the atmosphere at a temperature of no more than fifty degrees, and the power generated by the entire temperature differential power generation system is no less than 30kw.

Liang Yuan did not mark the purchase price of this system, and directly applied the data of the old product new processes in terms of the efficiency of thermoelectric materials. The step of the new materials and new processes was too big and scary, and Liang Yuan did not choose it. Even so, Zhu Yusheng still felt that the efficiency of the temperature difference generator calculated by Liang Yuan was very high.

However, due to someone applying too much, Zhu Yusheng could see various changes in Liang Yuan's design ideas, Zhu Yusheng couldn't figure out the problem for a while, just thought that Liang Yuan had chosen the wrong original data.

Of course, if the economic cost and technical difficulty are not considered, Zhu Yusheng thinks that Liang Yuan’s shell replacement technology is quite good, not only considering the space for upgrading and transformation of old tanks, but also using the transformation project to verify and reserve technology for the next generation of tanks.

"From the designer's ideas reflected in this design document, Xiao Liang's thinking is not only very active, but also has a much larger reading volume than his peers. It can be seen that Xiao Liang is still very hard-working in the junior class."

Although Zhu Yusheng has sentenced the death penalty to this design document, even if Zhu Yusheng does not believe that Li Yuanling will put the decision-making power of the Pakistan Tank Project in Liang Yuan's hands, through this document, we can know that the young man in front of him will have a great impact on Li Yuanling.

The core design idea in the document is Wu Zhonghua's professional scope. Zhu Yusheng believes that Li Yuanling and Wu Zhonghua must have helped Liang Yuan a lot. With the national conditions of the Republic and Liang Yuan's age, parents can allow Liang Yuan to be in a certain way to do something tank design. It can be seen that Liang Yuan has deviated from the simple concept of children and juniors in his family.

Listening to Zhu Yusheng's praise for someone's attitude towards studying at Dongda University, Zhao Tianshi was so happy. Thanks to the publicity of the two girls, Liang Yuan's final score re-examination record at Dongda University in recent years has become the main joke for Yuanjia middle and senior management when talking about someone on weekdays.

The talented boss often makes people doubt their life. It is rare to have such a flaw that looks very funny. In addition, the two girls did not have a good effect in the period, which made the insiders find it very interesting. They look at someone's mid-term exam with a happy attitude, and many departments even developed a small gambling game in which someone took several subjects.

Liang Yuan looked at Zhao Tianshi's bent mouth and knew what this guy was thinking. He glared at Zhao Tianshi with annoyance and said with a smile: "Old Zhu, based on my life experience since childhood, being criticized first is actually a good thing, which means that if things become something happen, you are afraid that you are proud and have a high tail, and then you will hit it first with praise. There is nothing good to start with. Give a date first so that you will not be bored by the slap below."

After communicating for so long, Zhu Yusheng grabbed Liang Yuan's temperament a little, and laughed and said, "Okay, I won't come to these stupid things anymore. From Lao Wu's side, I will call you Xiaoyuan."

Liang Yuan smiled and didn't respond, waiting for Zhu Yusheng to comment on his nonsense mental design.

"Xiaoyuan's idea of ​​replacing the shell of the old tank is still very good. Objectively speaking, the tank protection ideas and three-view stealth line diagram in this document have made some benefits for my work."

"Maybe it is because Xiaoyuan has not really been engaged in development work. It reflects typical shortcomings of novices in cost control and the selection of parameters of certain thermoelectric materials. As far as I know, Xiaoyuan's plan will be extremely difficult to implement even based on the technical foundation of Europe and the United States. For example, the superiority of thermoelectric materials, one of the core plans, has not been broken through forty years. Xiaoyuan's data selection is likely to be incorrect. Similarly, the cost of semiconductor power generation materials abroad is also very high. It is better to purchase a new generation of tanks from Europe and the United States to improve old tanks according to Xiaoyuan's plan."

"Of course, with the continuous development of technology, the efficiency of thermoelectric materials will sooner or later be broken by scientists, and the cost will drop to ordinary levels over time. At that time, Xiaoyuan's transformation plan will be useful."

"Mr. Zhu, what do you mean is that once the technical conditions are met, from the perspective of engineering application, my plan is completely feasible?" Liang Yuan asked happily.

"There is no problem with the idea, and there is no problem with the implementation of the lines and engineering principles. For example, assuming that the level of technological development next year meets the conditions in the document, this plan can be fully developed and continued as a formal project with great potential."

Zhu Yusheng nodded, approving Liang Yuan's imagination.

For Liang Yuan, as long as the design idea is correct and not off-difference, everything else is a trivial matter. Liang’s rich man wants money and people, and requires technology and technology. As long as the direction is right, he will not play with the storm.

Seeing Zhu Yusheng holding the three-view invisibility view without going to let go, Liang Yuan didn't plan to come back, and said with a smile: "As long as Mr. Zhu doesn't mind this document being messy, I'll leave it for you."

Zhu Yusheng shook his head happily, without even taking care of someone's mood, and kept saying: "Not messy, no messy at all. Xiaoyuan, I tell you that this picture in this document is the most valuable. I will check it carefully when I will do it, and maybe it will be used immediately."

Liang Yuan made up for some idea and thought that Zhu Yusheng really used stealth technology in advance on the 99 project. In addition to helping to attract fans, his combat effectiveness will not be lower than the original version.

"I just got a break from my whimsical plan. I and Mr. Zhu and I explained something clearly in advance so as not to cause any misunderstandings in the diplomatic field."

Zhu Yusheng saw that Liang Yuan was speaking very formally, turned his attention back from the sketch of the pl01 stealth tank on the drawing in his hand, and nodded solemnly indicating that he was listening.

"Since Brilliance will not receive research and development funds for the power field of Pakistan's new tank, then the relationship between the gem power pack and Pakistan's new tank project ends."

"Old Zhu, Zhao Tianshi, technical director Zhao Tianshi, can testify that the decision-making power of FAW in Pakistan's new tank project is really in my hands. I don't hide it from you. The contract between the Ministry of Railways and FAW is only a very small part of the gem order. At most two years, you will know where the main market of gems is. The limited purchase quantity of Pakistan's military, my mother really doesn't want FAW to involve too much energy to deal with it."

Although Liang Yuan didn't know how long it would take for the supercomputer to go offline, he was almost ready to hear such words. Liang Yuan also felt that he was going to succeed soon. It was nothing to say about the future application of Gem in advance.

Originally, the matter of tanks on the gems was Li Yuanling's next job based on Liang Yuan's idea of ​​trying his best to expand the scope of technical application. Although there are many improvements compared to the power pack of Long March 3, the technical foundation is ready-made. For example, Shangri-La Electric has become a giant in the air purifier industry in the North American market. It is now moving towards high-level food, electronics, medical and other air purification directions. Compared with tanks, the dust and sand protection problem is just within its own field. Although Pakistan may not have much procurement, it is completely a walk to take on this job, rather than Li Yuanling's interest in this field.

Now that Zhu Yusheng has finished talking about the various things about Institute 866, FAW naturally won’t waste resources because of an unvalued project. Even if Liang Yuan draws a clear line, it will become Li Yuanling’s first choice. Even if Li Yuanling has even put all her energy on the new fan, it is not easy to directly cut off this project.

"Of course, I have seen all the plans I gave you just now. The continued investment in FAW in this field is true. It is in the name of the 59th reform project, not the name of Pakistan's new tank. If Pakistan does not choose the gem power pack, it will be cleared up if Pakistan intends to apply the gem power pack to the new tank, so that Pakistan can only go forward and discuss with the civil aviation import and export company. In order to avoid engaging FAW's R&D energy, the export business agent of the gem power pack will be given to the civil aviation import and export company."
