I have a little black hole

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

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

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

One is the room temperature requirement.The working temperature range required by most electronic devices on the detector is 0~40°C.Of course, a certain fluctuation value is also within the allowable range.

The second is constant temperature requirements.In order to ensure that the precision instruments and equipment on the planet work well, their temperature must be constant and do not change with time; in many cases, the overall temperature must also 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, the working point is in the low temperature range, the detector should provide corresponding low temperature working conditions.

Some refrigeration systems and thermoelectric power generation systems on the planet require high temperature conditions.If the detector cannot meet the temperature requirements of these components, a "strike" of the device may also occur.

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

The local or overall isothermalization of the detector not only helps to improve its thermal performance, but also simplifies the thermal design of the detector, simplifies the thermal test and increases 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.

In general, the passive thermal control method refers to the installation of thermal insulation material on the outside of the detector housing or components, and the application of a coating with a high emission-absorption ratio or a 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 used for detector thermal control.

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

In short, when performing thermal control on the detector, various relevant factors must be considered, and measures and plans for thermal control must be selected to determine the best.

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 optimize the anti-collision system to avoid the appearance of the detector. It is difficult for the impact layer to fall off after being subjected to a destructive impact, thus dragging on the detector.

After all, the multi-layer anti-collision layer designed by them requires such operation after impact damage. Abandoning the damaged part can lighten the detector and allow more flexible maneuvering to avoid more possible impacts, thereby extending the detection. The service life of the device.

These optimized designs are things that Kuafu and Lei Tiantang did not consider. After all, they are not specialized in designing satellites and detectors. The requirements for professional knowledge in this respect are still very high. This is exactly what Lei Tiantang has to them. The reason why the work is very satisfactory.

"Well, 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 of the cafeteria send themselves a sumptuous dinner, and after a beautiful meal, Lei Tiantang went down to the underground laboratory, and officially and Kuafu began to carry out the final test work 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 normal report sound of Kuafu's items, the entire test work was carried out in an orderly manner according to the established steps.

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

"Oh, boss, your mind is moving very fast! Indeed, after the production of these detectors, I have carried out preliminary tests. Even if there are problems, I have revised them immediately, so the test is so smooth. Of course is normal!

But the rest of the dynamic testing will be a little more troublesome. Although I can do this kind of testing, there are more equipments that need to be used. The key is that these equipments are not available in our underground laboratory. I still have to manufacture these test equipment first, that would be too much time!

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

"You'll save trouble! Forget it, you say, how to test, you say I'll do it!" Lei Tiantang grinned helplessly.

"Good boss, because these of our detectors are true deep space detectors, the performance requirements are much higher than those of the satellites and other detectors launched by the company into Earth orbit, so more work is required for dynamic testing!

In order to carry out dynamic testing, I also specially produced two more of each type of detector, specifically for destructive dynamic testing.

Boss, you need to perform vibration flight test, high-speed motion test, high-speed impact test, etc. according to my requirements. If you listen to these test names, you must know the boss, how do you do these tests?Kuafu asked with a smile.

"Get out! Are you your boss, am I a fool?! 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. I am happy.

"Yes, the main content of this test is to test the scene of these detectors when they 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 will also need to test this. Content." Kuafu didn't mind his boss's words at all, and explained to himself with a smile, anyway, he was used to it every day.
