Chapter 555

Of course, this kind of temperature adjustment is not just antifreeze. Most of the detectors in this series will be ejected into the star system not far from the small black hole to carry out the exploration mission.

After the detectors enter the stellar system, as the detectors get closer and closer to the stars, they are facing the thermal radiation of the stars, which makes the temperature of the detectors rise to more than 1000 degrees, and there is no air in space to help them dissipate heat, so these detectors have to consider the problem of cooling down again!

These detectors need thermal control system to help them dissipate heat. For many detectors, due to different instruments and equipment, their working mode, thermal characteristics and temperature requirements are also different, which can be roughly divided into the following categories.

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

Second, constant temperature requirements. In order to ensure that the precise instruments and equipment on the satellite work well, its temperature must be constant and does not change with time; in many cases, the overall temperature balance is also required.

Third, high and low temperature requirements. For some components on the detector, such as the infrared optical detection element of remote sensor, its working point is in the low temperature range, so the detector should provide corresponding low-temperature working conditions.

On the other hand, the refrigeration system and thermoelectric power generation system on some satellites need high temperature conditions. If the detector can not meet the temperature requirements of these components, the equipment "strike" may also occur.

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

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

So much said, how to realize the thermal control of the detector? This is mainly achieved by passive thermal control method and active thermal control method.

Generally speaking, passive thermal control method refers to installing thermal insulation materials on the outside of detector shell or components, coating with high emission absorption ratio or low emission absorption ratio to control temperature change.

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

Because the passive thermal control method does not have the ability of automatic adjustment, it can not adapt to the situation of large change of internal and external heat flow, especially the change of internal heat source. Therefore, active thermal control method should be considered, such as adding blinds, convection system, electric heater and so on.

In a word, all kinds of relevant factors must be considered in the thermal control of the detector, and the measures and schemes of thermal control should be selected.

So the deep space lab helped them to re optimize and design the temperature control system of all detectors. Of course, they did more than that. They also helped to optimize the anti-collision system, so as to avoid the situation that the anti-collision layer of the detector is difficult to fall off after a destructive impact, thus dragging down the detector.

After all, the multi-layer anti-collision layer designed by them needs this kind of operation after encountering impact damage. Discarding the damaged part can reduce the load of the detector, and can conduct more flexible maneuvering to avoid more possible impacts, so as to prolong the service life of the detector.

These optimized designs are things that Kuafu and Lei Tiantang can't consider. After all, they are not specialized in designing satellites and detectors. In this respect, the requirements for professional knowledge are still very high, which is the reason why Lei Tiantang is very satisfied with their work.

"Well, I can't get rid of this test. I can't wait to throw these guys over there!" Lei Tian Tang said with a smile.

Let the canteen staff to send themselves a sumptuous dinner, Meimei after a big meal, Lei Tiantang went down to the underground laboratory, officially and Kuafu began to carry out the final test of these detectors.

"Nuclear battery performance is all normal! Power on test all normal! Control system test normal! ... "with Kuafu's normal report, the whole test work was carried out in an orderly manner according to the established steps.

"Well, since all static tests are OK, let's do dynamic testing! I think that's why you asked me to take the test. " Lei Tian Tang said with a smile.

"Ha ha, boss, your brain is very fast! Indeed, after the completion of the production of these detectors, I conducted preliminary tests, even if there were problems, I immediately revised them, so it is normal that the tests are so smooth!

If there is no surplus dynamic test, it will be more troublesome. Although I can do such test, there are more equipment to be used. The key is that our underground laboratory does not have these equipment. If we want to carry out such test, I have to manufacture these test equipment first, which will take too much time!But boss, you can use your ability to help me complete this test, and your ability is more convenient than using equipment, such a job is not looking for you, I am looking for who! " Kuafu replied with a smile.

"You will save time! Forget it, you say, how to test, you say I'll do it! " Lei Tiantang helpless smile curse way.

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

For dynamic testing, I also specially produced two more detectors of each type for destructive dynamic testing.

Boss, you need to carry out vibration flight test, high-speed motion test, high-speed impact test, etc. according to the name of these tests, you must know how to do these tests, boss? " Kuafu asked with a smile.

"Go away! Am I a fool when you are your boss?! I can't understand such a straightforward thing?! Hurry up, stop talking nonsense, and test vibration flight first, right? " Lei Tian Tang was given Qi Yue by Kuafu's question.

"Yes, boss, this test mainly tests the scene of these detectors when they are ejected by the small black hole you control. In the future, our company will also need to test this content if we launch deep space probes from the earth to the outer solar system." Kuafu Si didn't mind her boss's words, she explained with a smile, anyway, she had to scold her every day, she was used to it.
