Thermal transfer technology that transfers heat from low-temperature objects to high-temperature objects is amazing, but there are not many applications for it.
The earliest heat transfer technology in the Kingdom can be traced back to before the floating island. At that time, the heat utilization rate was very low and could only be used within the range of minus ten degrees to plus eighty degrees.
To say it is useless, it is indeed somewhat useful, but to say it is useful, it cannot be used directly to create steam. In an environment where coal, coking coal and other fuels started relatively early and are cheap enough, it seems a bit useless.
The focus is on the cost savings. Compared with the manufacturing difficulty and cost, it is almost negligible. Production-oriented enterprises would rather burn more coal.
This technology is mainly developed in Phoenix Power Grid. As a power infrastructure unit, improving coal-fired thermal efficiency is a very clear achievement indicator. The two legs of the power grid are equipment efficiency and heat transfer.
It is conceivable that the focus of the power grid must be on the high-temperature area where breakthroughs in heat transfer technology are achieved.
The first version is mainly used to control the temperature of the coal-burning area, and the extruded heat is used to preheat the incoming water. At a temperature of 110 to 120 degrees, heat transfer can be fully applied in the steam recovery network to avoid corrosion in the pipes caused by repeated condensation. Above 120 degrees, it can be used in more places, such as insulating pipes leading to generators. Above 170 degrees, you can participate in the thermal management of the main steam pipe.
Up to now, Phoenix Power Grid has achieved a high temperature section of heat exchange of 206 degrees. At the same time, in the difficult branch of technology development, it continues to abandon the lower limit of heat absorption. This version of 206 degrees can only be used in environments above 32 degrees Celsius.
What is needed now is minus two hundred degrees.
Wang Qi transferred the institute's authorization information and asked people from the Industrial and Commercial Administration to track the direction and development of the technology.
Feedback found that this technology is mainly used in magic workshops and chemical industry chemistry laboratories to control environmental variables on a small scale.
To control temperature variables, the mainstream still uses ice, fire or similar magic. Heat transfer technology is a by-product of studying the correlation between ice trees and ice magic. The difference is reflected in the relatively large investment.
The carrier of heat transfer is the magic array. The current laboratory equipment is produced by a small company with only a few dozen people. The smallest and ordinary temperature variable control cabinet with a capacity of 20 liters costs 2,300 yuan.
More than 2,000 yuan may seem like a small amount. With the current average daily wage of six yuan in China, it is not enough to go without food or drink for a year.
When it comes to using magic, as long as the mage knows how to do it, even if he is not very good at it, the cost of casting materials is only a few dozen yuan at most. An elemental mage doesn't even need materials. The disadvantage is that manual control is not as stable as equipment control.
After consultation with the family-owned company that provides equipment, called Aola Workshop, we learned that they are actually more professional than Phoenix Power Grid in heat transfer technology.
Phoenix Power Grid only considers power generation, so it only pursues the high-temperature section. However, Aura Workshop is connected to other magic workshops and chemical laboratories. It does have low-temperature needs, but it is not extreme enough.
The best low-temperature control cabinet they have ever delivered has a measured working low temperature of minus 114 degrees, while the high temperature range is quite different, with the measured temperature being as high as 110 degrees. The two temperatures are extreme values given by different types of equipment.
The heat treatment method is also different from that of Phoenix Power Grid.
The heat absorbed by Phoenix Power Grid through heat transfer is provided to water bodies or steam pipes as much as possible. In the later stage, it is basically from equipment to equipment and has nothing to do with the ambient temperature.
The equipment of Aura Workshop exchanges heat between the environment inside the box and the atmosphere. Judging from the heat exchange objects, it is indeed more in line with the needs of this extraterrestrial mission.
For spacesuit testing, just use a spherical cabin that can hold the spacesuit upright. Four cubes are enough. If the heat is exchanged over a relatively long period of time, it will not put too much pressure on the external temperature. At worst, two fans will be added.
Moreover, Blue Sky Heavy Industry is a government-owned enterprise, and the task is assigned directly by Wang Qi, so there is no need to consider the financial cost too much.
Although minus 114 degrees is further from the target than liquid methane, Wang Qi still provided the Aura Workshop to the Blue Sky Heavy Industry project team.
Speaking of which, Blue Sky Heavy Industry also considered the issue of heat control in the cockpit during the development of new aviation suits. However, the fighter aircraft project included the development of a new turbojet engine, and the progress was not as fast as that of the transport aircraft. Without test flight data, it could only be based on the lightning flash. The accumulated experience focuses on load resistance and oxygen supply.
And even if they go to check, they will probably use the original technology of the institute, and they may not be able to trace it to the Aola workshop. After all, the cockpit temperature is not extreme. The heat above the human body's comfortable temperature can be released at any point behind the pilot. Just fine, the metal wall of the engine inlet is a good heat unloading area.
Sure enough, he found the right person for this matter. When Li Xiang checked the progress every ten days, he found that Aola Workshop dared to take the order.
After asking a few people, I learned that there is also a trick to heat transfer, which is to transfer in sections.
Just like the initial technology span is only 90 degrees Celsius, the temperature span of Phoenix Power Grid technology is less than 200 degrees Celsius. Since the temperature span of one exchange is not enough, it is better to divide it into several exchange segments.
It’s not that the people at Aola Workshop are smart and other manufacturers are stupid, it’s because as a family-owned small business, their R&D capabilities are not as good as those of the big guys, so they must take some detours.
Detours are not necessarily the best solution, but for this small device with a single function, the market size is limited. Except for some limited ones in the country, only the most fashionable alchemists abroad will buy it. Since the market is small, there are no major manufacturers to develop alternatives, and it is impossible to get a few sets of methane liquid cooling equipment in the laboratory, so their business has been able to continue.
With the idea in mind, it was still difficult to do it. News soon came that the low-temperature material was stuck again.
Low-temperature resistant materials can be a subject in itself. With such a small population in the Phoenix Kingdom, it is naturally impossible to set up a special subject for it.
Most of the existing low-temperature-resistant materials come from "exhaustive steelmaking."
"Exhaustive steelmaking" is Phoenix Steel's unique materials research method, which relies entirely on steel pricing power and a government-owned share structure without profit pressure.
Exhaustion will not yield good results. After the first few years of the explosive period, the results have become less and less, and we have to move towards theoretical guidance. The establishment of this theory lies in the summary of the rules recorded by tens of thousands of small furnace experimental subjects. It is not perfect to this day.
In the field of low-temperature resistance, gold chemical and other related companies use less than three types of steel. In many cases, one type can solve the problem.
But the magic circle is different.
There is steel at home that can withstand minus 200 degrees Celsius. Even if it is not 100% confirmed now, there is a high probability that it can be found out from exhaustive data that it is at least barely usable.
But the magic materials are very complex, and there is no way to make a magic array using the steel-on-steel model.
As for the goal of minus two hundred degrees, liquid materials will be completely eliminated, and paints are also very toxic. The most stable ones may be powders. However, the specific impact of ultra-low temperature depends on experimental results.
Wang Qi read the feedback and decided to let them try it.
Of course we can't count on them.
If it doesn't work here, Solaris can only open the door once. In order to avoid opening the door three times or more, a series of material sample boxes must be specially prepared. The task will be handed over to the "alien magic" who is tossing it. "Testing Machine" magic research team.
They don't have to do it themselves. After all, the institute, now the National Academy of Sciences, doesn't produce any materials itself. It mainly relies on logistics personnel to communicate with various manufacturers to obtain samples.
