I Have a Little Black Hole

Of course, such temperature adjustment is not just antifreeze. Most of these detectors are to be ejected by Lei Tiantang into the star system not far from the small black hole to perform detection tasks.

After the detector enters that star system, as the detector gets closer and closer to the star, they are facing the thermal radiation of the star, which makes the temperature of the detector even rise to more than 1000 degrees. And there's no air to help them dissipate heat, so these detectors have to think about cooling again!

These detectors need a thermal control system to help them dissipate heat. For many detectors, due to the different instruments and equipment on them, their working modes, thermal characteristics and requirements for temperature are also different. into the following categories.

One is the room temperature requirement. Most of the electronics on the detector are required to operate in the temperature range of 0 to 40°C. Of course, a certain fluctuation value is also within the permitted range.

The second is the constant temperature requirement. In order to ensure that the precision instruments and equipment on the star 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, its operating point is in the low temperature range, and the detector must provide it with corresponding low temperature working conditions.

On the other hand, the refrigeration systems and thermoelectric power generation systems on some satellites require high temperature conditions. If the detector cannot meet the temperature requirements of these components, it is also possible for the equipment to strike.

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

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

Having said so much, 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 means of installing thermal insulation materials on the exterior of the detector housing or components, applying a coating with a high emission-absorption ratio or a low emission-absorption ratio, etc. to control temperature changes.

These measures are simple in construction, relatively low in cost, good in versatility, and suitable for large-scale use. It is the basic and main means used for thermal control of detectors.

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 varies greatly, especially the change of the internal heat source. At this time, an active thermal control method should be considered, such as adding shutters to the corresponding components , convection systems, electric heaters, etc.

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

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

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

These optimization designs are things that Kuafu and Lei Tiantang cannot consider. After all, they are not specialized in designing satellites and detectors. The requirements for professional knowledge in this regard are still very high, which is exactly what Lei Tiantang has for them The reason why the job is so satisfying.

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

Let the staff in the cafeteria give him a sumptuous dinner,

After Meimei had a big meal, Lei Tiantang went down to the underground laboratory and officially started the final test work with Kuafu on these detectors.

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 Kuafu's normal reports, the entire test work was carried out 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 that's why you asked me to take the test! Lei Tiantang said with a smile.

Hehe, boss, you're thinking fast! Indeed, after the production of these detectors was completed, I conducted preliminary tests. Even if there were any problems, I immediately re-modified them, so of course the test went smoothly. is normal!

However, the rest of the dynamic test will be a little more troublesome. Although I can do this kind of test, I need to use more equipment. The key is that we don’t have these equipment in our underground laboratory yet. I have to build these test equipment first, that's too much time consuming!

But boss, you can use your ability to help me complete such a test, and boss, your ability is more convenient to use than the equipment, this kind of work is not looking for you, I am looking for someone! Kuafu replied with a smile.

You'll save trouble! Forget it, tell me how you want to test, you tell me to do it! Lei Tiantang laughed helplessly and scolded.

Okay boss, since our probes are real deep space probes, the performance requirements are much higher than those of the satellites and other probes that the company launches into Earth orbit, so there is more work to be done in dynamic testing!

For dynamic testing, I also produced two more probes of each type specifically for destructive dynamic testing.

Boss, you need to test them for vibration flight test, high-speed motion test, high-speed impact test, etc. according to my requirements. Listening to the names of these tests, you must know what these tests need to be done, right? Kwafu asked with a smile.

Fuck off! I'm a fool when you are your boss?! I can't understand such a straightforward thing?! Hurry up, don't talk nonsense, test vibration flight first, right? Lei Tiantang was praised by his father for this question So happy.

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