Of course, such temperature adjustment is not just anti-freezing. Most of the detectors in this series are to be ejected by Lei Tiantang into the star system not far from the small black hole for detection missions.

After the probe enters that star system, as the probe gets closer and closer to the star, they are facing the thermal radiation of the star, which makes the temperature of the probe even rise above 1000 degrees, while in space There is no air to help them dissipate heat, so these detectors have to consider cooling down again!

These detectors need a thermal control system to help them dissipate heat. For many detectors, because of the different instruments and equipment mounted on them, their working modes, thermal characteristics, and temperature requirements are also different, so it can be summarized roughly. Divided into the following categories.

One is room temperature requirements. Most of the electronic equipment on the detector requires a working temperature range of 0-40°C. Of course, a certain fluctuation value is also within the allowable range.

The second is the constant temperature requirement. In order to ensure that the precision instruments and equipment on the planet work well, their temperature must be constant and not change with time; in many cases, the overall temperature is also required to be balanced.

The third is high and low temperature requirements. For some components on the detector, such as the infrared optical detection element of the remote sensor, whose working point is in the low temperature range, the detector must provide it with corresponding low temperature working conditions.

However, some satellite refrigeration systems and thermoelectric power generation systems require high temperature conditions. If the detector cannot meet the temperature requirements of these components, then equipment "strikes" may also occur.

The fourth point is isothermal requirements. This requirement is put forward from the perspective of the temperature field requirements and thermal design of the detector components, which means that by adopting certain thermal control measures and reasonable heat source layout, the temperature of the local area or the entire star on the detector is basically equal, that is, The so-called isothermalization.

The partial or overall isothermalization of the detector not only helps to improve its thermal performance, but also helps simplify the thermal design of the detector, simplify the thermal test, and increase the reliability of the thermal design.

Having said that, how to realize the thermal control of the detector? This is mainly achieved through passive thermal control methods and active thermal control methods.

Generally speaking, the passive thermal control method refers to the installation of thermal insulation materials on the outside of the detector housing or components, and the application of coatings with high emission-absorption ratio or low emission-absorption ratio to control temperature changes.

These measures have simple construction, relatively low cost, good versatility, and are suitable for large-area use. It is the basic and main method for thermal control of the detector.

Since the passive thermal control method does not have the ability to automatically adjust, it cannot adapt to the situation where the internal and external heat flow changes greatly, especially the change of the internal heat source. At this time, active thermal control methods should be considered, such as adding shutters to the corresponding components. , Convection system, electric heater, etc.

In short, when performing thermal control on the detector, various related factors must be considered, and thermal control measures and schemes should be determined based on the best.

So the Deep Space Laboratory helped them to re-optimize and design the temperature control system of all the detectors. Of course, they did more than that. They also helped to re-optimize the anti-collision system to avoid the occurrence of detectors It is difficult for the impact layer to fall off after a destructive impact, thereby dragging down the detector.

After all, the multi-layer anti-collision layer they designed requires such an operation after encountering impact damage. Abandoning the damaged part can reduce the burden on the detector, and can perform more flexible maneuvers to avoid more possible impacts, thereby prolonging the detection. The service life of the device.

These optimization designs are things that Kuafu and Lei Tiantang cannot consider. After all, they are not professionally designing satellites and detectors. The requirements for professional knowledge in this respect are still very high. This is exactly what Lei Tiantang has for them. The reason for the job satisfaction.

"Well, then I can't push this test, and I can't wait to throw these guys over there!" Lei Tiantang said with a smile.

Let the staff in the cafeteria give herself a sumptuous dinner. After Midea had a big meal, Lei Tiantang went down to the underground laboratory, and officially started the final test work on these detectors with Kuafu. .

"The performance of the nuclear battery is all normal! The power-on test is all normal! The control system test is normal!..." With the sound of a normal report from Kuafu, the entire test work proceeded in an orderly manner according to the established steps.

"Well, since all the static tests are normal, let's do the dynamic tests! I think this is the reason you asked me to participate in the test!" Lei Tiantang said with a smile.

"Hehe, boss, your brains are turning very fast! Indeed, I have conducted preliminary tests on these detectors after the production is completed. Even if there are problems, I immediately re-modified them, so of course the test is so smooth. is normal!

But the rest of the dynamic test will be a bit more troublesome. Although I can also do this kind of test, I need to use more equipment. The key point is that our underground laboratory still has all these equipment. No, I have to manufacture these test equipment first to carry out such tests, it would be too time-consuming!

But boss, you can use your abilities to help me complete such tests, and your boss’s abilities are more convenient to use than equipment. This kind of work does not find you or who I will find! "Quafu replied with a smile.

"You will save trouble! Forget it, just tell me how to test, you say I will do it!" Lei Tiantang cursed with a helpless smile.

"Good boss, because our detectors are real deep space detectors, the performance requirements are much higher than those of the company's satellites and other detectors launched into the earth orbit, so there is more work to be done for dynamic testing!

In order to conduct dynamic testing, I also specially produced two more detectors of each type, specifically for destructive dynamic testing.

Boss, you need to perform vibration flight tests, high-speed motion tests, high-speed impact tests and other tests on them according to my requirements. Listening to the names of these tests, you must know how these tests need to be done, right? "Quafu asked with a smile.

"Fuck off! Are you a fool when you are your boss?! I can't understand such a straightforward thing?! Hurry up, stop talking nonsense, first test vibration flight, right?" Lei Tiantang was praised by his father. I am happy.

"Yes, boss, this test content is mainly to test the scene when these detectors are ejected by the boss using the small black hole you control. In the future, if our company launches deep space probes from the earth to the outside of the solar system, we also need to test this. Content." Kuafu didn't mind the words of his boss at all, he smiled and explained to himself, anyway, he was used to scolding like this every day.
