Black technology starts from the steel suit

Chapter 161 Chapter 161

"Then I'm counting on you, Professor Wang." Director Wang said very solemnly: "This is some of our technical specifications for it, please!"

"Let me take a look first, please wait a moment." Although Wang Feng agreed, he would do what he could, but if it was beyond his ability, then he could only refuse, or ask the other party to modify it. Not God.

"Please go ahead, I'm sure I have time, so I'm not in a hurry." Director Wang sat down and began to taste the tea slowly, although there was no trace of tea in the teapot or cup, it was pure boiled water.

Wang Feng slowly flipped through the rough technical requirements report drafted over there. It was actually similar to what was required by the Energy Bureau, but compared to the transitional use requirements of six months to one year, Aviation Science The requirements over there are much higher, but the energy conversion efficiency is still second, only about 10% higher, and he is still very confident.

The most important one is the requirement of structural stability and service life, because stable thermal energy conversion needs to rely on a stable structure; the requirement of service life is very simple. Just to make it last longer?

Of course, the use requirements should not be too high, and there should not be any harsh use conditions, such as a specific temperature...here refers to ultra-low temperature or ultra-high temperature, and what high-intensity magnetic field... Where do you get 2 on Mars? A magnetic field of t?
"Is there any problem on your side, Director Yu?" Wang Feng flipped through the documents, and asked Director Yu who hadn't spoken for a long time, but was simply drinking plain water.

"You two go ahead, I'm not in a hurry." Director Yu said unhurriedly.

"There is nothing wrong with the others, but the 30-year service life is a bit too long. In fact, according to the speed of technological upgrading, there is no need to design such a long service life, because even the conversion device can work. For such a long time, it is impossible for other parts to persist for such a long time." After watching it, Wang Feng said to Director Wang.

"You can design towards this goal first. As for whether you can achieve it in the end, we can talk about it at that time. The next launch plan is two years away, and this time should be enough for you to achieve some phased results. It worked out." Director Wang explained.

"Actually, we don't just want to use it on spacecraft. This time, the ideas of those colleagues in the Energy Bureau, I think, are particularly good. We can use thermoelectric power generation technology as a conventional power generation technology."

"After all, to be honest, in terms of materials science, especially in terms of high-strength, high pressure resistance, and corrosion-resistant materials, there are too many backward developed countries. Even if we are already advanced in steam turbines and gas turbines It’s one of them, but we still rely on imports for the technology of key components.”

"Basically, it mainly needs to be imported. Things that we have not been able to manufacture are basically slaughtered head-on. The technical research organized by the Shanghai Research Institute only realized the localization of most of the components. But it has reduced our steam turbine production cost by half!" Director Wang said with a wry smile.

"No way, who made us start late?" Wang Feng could only say consolingly, although he was suspected of deceiving himself, after all, we did delay a lot of things during that time, and this was just one of them. Just a trivial part.

“我国超临界、超超临界机组发展较晚。我国于上世纪80年代后期开始从国外引进30万千瓦、60万千瓦亚临界机组，第一台超临界机组于1992年6月投产于上海石洞口二厂（2×600MW， 25.4MPa， 541/569℃）。从引进到完全消化吸收，我们用20年的时间。”

"It's been more than 20 years. In such a long time, I don't know how many generations have been left behind!" Director Wang said with great regret: "Since it is difficult for us to catch up with others in this respect, it is very difficult for us to overtake on curves." It's our best chance."

"Of course, this is a long-term job. We don't require you to achieve this goal in a short period of time. After all, we all know that this is unrealistic, and we are not sure whether we can achieve this goal. experts to conduct research and make judgments during the research process.”

It is not so easy to overtake another car on a curve, otherwise, everyone should find a shortcut. ...can it be done?
Think about it, compared with the traditional power generation method that needs to convert thermal energy into mechanical energy first, and then into electrical energy, electrothermal materials have no mechanical movement during the energy conversion process, and do not require Freon or other chemical fluid media, so thermoelectric devices have Clean and pollution-free, no transmission parts, no noise and long life.

Thermoelectric materials have been widely used in the fields of industrial waste heat recovery, automobile exhaust heat energy conversion, solar power generation, deep space spacecraft power generation devices, mobile small power generation devices, small refrigeration devices and portable refrigerators, especially in the military market. Concealed submersible detectors, reconnaissance equipment, and even submersibles, etc., can't even be detected by sonar... How scary it must be!
In recent years, the huge civilian market demand and the rapid development of modern science and technology have made the research of high-performance thermoelectric materials attract the attention of researchers from all over the world.The research and application of thermoelectric materials is of great significance to today's increasingly scarce non-renewable resources and increasingly serious environmental pollution, and even more significant to the country.

This is the reason why they are willing to provide such strong support after Wang Feng transferred to this research.Because no one can resist such a temptation.

"So as you can see, we hope that its production materials are as easy to obtain as possible, and the production cost is as low as possible. This low cost is not relative to space activities, but compared to For a steam turbine at the same power."

"Then this requirement is indeed a bit high." Wang Feng said with some embarrassment. Any research starts from scratch. The way to find the next way to the destination, which is why a literature review is done before doing research.

Human beings have come a long way in the field of thermoelectric materials, but unfortunately as far as the current situation is concerned, either the raw materials for making 6-point materials are scarce and expensive; or the production technology is complicated and the yield rate is very low; or That is, the production cost is relatively cheap, but the efficiency is also very low, and it can only be used as a supplementary means, not the main means of power generation...

"I can only say that I will do my best." Wang Feng couldn't make a promise.
