Liu Lin read all the information of the portable thermostat in detail.

I was overjoyed and rich!

It didn't take much effort to get it.

It's a lot of money.

The difficulty is much simpler than the h screen, and it can be said that it is picked up for nothing.

The meat that reaches the mouth, do not eat it in vain.

It's an idiot not to eat!

portable thermostats;

Chip requirements: PU adopts more than four cores, multi-line operation, running frequency of more than 25GHz, can meet the LTE AT21 standard, its peak downlink rate is required to reach more than 1Gbps, the uplink rate can reach 180BPS, the speed can reach 172BPS, and it can also support L1+L5 dual-band GPS ultra-accurate positioning.

It seems that Huawei released the Kirin 980 the year before last, that is, in the second half of 2018, I don't know how the performance is, whether it is enough or not.

If it can be provided in China, it is definitely much better than buying it from abroad, at least there is no fear of getting stuck.

Check it out, Liu Lin minimized the data switch and opened the website.

A few light taps on the keyboard.

Search (Kirin 980) technical data.

After Liu Lin searched carefully for more than ten minutes, he picked up the mobile phone on the desktop, swiped his finger on the screen for a long time, found Boss Ren's phone, and called it directly without thinking about it.

"Toot, toot, toot"

"Hello Mr. Liu Lin, I'm Boss Ren?" The mobile phone rang a few times, and then it was connected, and an old and heroic voice came into Liu Lin's ears.

"Hello Boss Ren, I didn't bother you!" Liu Lin asked.

"Don't bother, I can make you call, and you have to be free if you're not available. Boss Ren smiled happily, attracting the sideways glances of several people who sang tea with him.

"Boss Ren, I'm a little embarrassed when you say that!" Liu Lin put away his nonsense and said directly: "Boss Ren, I have nothing to do this time in the Three Treasures Palace, and I am here to ask you for help!"

"Mr. Liu, you said, if you can help, my old Ren, there is no other thing!" Boss Ren said so, but he didn't beat the drum in his heart, so that Liu Lin could personally call him for help, it should be a technical problem, and it should definitely not be a trivial matter.

I hope it's not too difficult!

Boss Ren didn't know the bottom of his heart.

The main reason is that the starting point of Jiu'an Technology is too high, and ordinary people can't hold it!

You must know that Jiu'an Technology is synonymous with black technology.

Ordinary technical problems can be solved by the word "hehe" for Jiu'an Technology.

"Last year, your company released a mobile phone chip core (Kirin 980), I have a product that may be used, I can't get a few samples for me, I'll do an experiment!" Liu Lin didn't go around the changer, he went straight to the topic, he was a person of this level, and then he went around the bend, it was all unnecessary.

Liu Lin's words made Boss Ren's heart tighten, Jiu'an Technology wants a mobile phone chip core (Kirin 980), what do you want to do, won't you also make mobile phones, that's not a good phenomenon!

Jiu'an Technology manufactures mobile phones?

If your company is on the mobile phone against Jiu'an Technology, although your mobile phone department is the boss in Guohua, but a pair of Jiu'an Technology, it is still unknown who will win or lose.

Because Jiu'an Technology is synonymous with black technology, the ghost knows what black technology will be put on the mobile phone.

In the face of absolute strength, all means have to kneel.

"No problem, if you want me to send it to you, or what? Is a hundred enough? Boss Ren thought so in his heart, but he still agreed very happily.

Besides, it's just a guess, isn't it?

"That's enough, not so much, ten or eight are enough. Liu Lin was very happy and thanked: "No need to send it, wait for me to arrange someone to bring it, you can help me get ready!"

"It's so urgent, okay, I'll let people prepare it right away!" Boss Ren said very happily.

"Then thank you, I'll trouble you, there's no problem just like this, next time you come to Yulin, I'll invite you to a big meal and express your gratitude!" Liu Lin immediately drew a big cake for Boss Ren.

"Okay, just wait for your words!" After Boss Ren finished speaking, his eyes turned around and asked, "Mr. Liu, what kind of black technology do you want this chip to do?"

"Well, there is a product to use, try to use it!" As soon as Liu Lin finished speaking, he listened to Bai Mingren's extraneous meaning, probably because he was afraid that he would make a mobile phone, so he said: "I've been bored recently and designed a gadget." ”

"Gadgets?" Boss Ren choked for a moment, and he was speechless when he said this, and he didn't know how to answer it all of a sudden.

Gadgets?

Difficulty: I'm old and can't keep up with the times?

"Yes, gadgets, keep it secret for the time being, but a lot will be known!" Liu Lin was not ready to let out the news.

"Then I'm looking forward to it!"

“”

"Boss, whose phone is it?" After Boss Ren hung up the phone, he put the phone on the purple coffee table in front of him, Yu Chengdong couldn't wait, and asked curiously.

"Liu Lin, the boss of Jiu'an Technology!" Boss Ren replied like a fugue, thinking in his heart, what did Liu Lin suddenly want this mobile phone chip to do?

Is it really a mobile phone?

"Mr. Liu, why did he call you?"

"He wants (Kirin 980) mobile phone chips. "Boss Ren couldn't figure it out for a while, so he didn't care, the boat was naturally straight to the bridge, and he would know when the time came.

"Jiu'an Technology wants to make a mobile phone?" Yu Chengdong's face changed, his hand shook, and he said in horror.

"Probably not!"

"Probably not, if you want to make a mobile phone, you shouldn't ask us to supply chips!" Liang Hua, who was sitting on the other side of Boss Ren, shook his head and objected.

"Otherwise, what does he want a mobile phone chip for?" Yu Chengdong thought that it seemed to be the same thing, so he put down his heart.

There's no way, there are too many black technologies in Jiu'an Technology, and throwing one out at random will scare many people to death.

You don't look at the wireless charger for mobile phones from the very beginning, sewage treatment system, H battery, wireless system, etc., which one is not the existence of scaring people.

"He said that he will know in a few days, and I estimate that it should be announced at the press conference of the Science and Technology City, and it is only ten days away. After Boss Ren finished speaking, he continued: "Chengdong, you go and equip a hundred pieces (Kirin 980) and pack them, and Mr. Liu will send someone to pick them up in a while!"

"So urgent?" asked Yu Chengdong in surprise.

"Yes, let's go and prepare first, you can go and get the chip ready first, and we'll discuss the mobile phone conference later!"

"Okay, I'll arrange someone to prepare immediately!" Yu Chengdong nodded, picked up his mobile phone and made a call to go out, and explained!

“”

After Liu Lin hung up the phone, he immediately called Li Yong's phone!

"Boss, I'm Li Yong, what's the matter?" The phone rang, and Li Tong's voice came out.

"Brother Yong, I just called Huawei's boss Ren and asked him for some (Kirin 980) mobile phone chips, you can arrange someone for me now, and help me bring it back immediately, the faster the better, I'll wait to use it!" After Liu Lin finished explaining, he said: "Wait a minute, I'll send you the contact number!"

"Okay boss, I'll arrange it right away, do you want to go over and get it now?" Li Yong said in a deep voice.

"Yes, go right away. Liu Lin nodded.

"Okay, I understand, I'll arrange it!" Li Yong didn't talk nonsense, and after hanging up the phone, he immediately made a few calls to arrange things.

The chip thing is done, and now the X magnetic field device is still missing.

By the way, I almost forgot the battery, Liu Lin slapped his forehead, how could he forget about this, and asked Liu Cao if there was an H battery in the laboratory.

"Liu Cao, is there an H battery in the laboratory now?" Liu Lin called Liu Cao's phone, and asked after connecting.

"Yes, there are in warehouse No. 3, boss, you think, I'll help you get it, there are various models, boss, what model do you want?"

"Give me a few of each of your models, I'll use them for experiments!" Liu Lin said happily when he heard this.

"Okay, I'll get it to me right away!"

“”

Liu Lin put down his mobile phone, put the X magnetic field device, and typed it out with a printer.

X-magnetic field device: It is an oscillating ion band derived from the electric field and the magnetic field that are in phase and perpendicular to each other in space, and is beyond the magnetic field in the form of waves.

The changing ions and the changing magnetic field constitute a unified field, and the temperature, humidity, etc. in the magnetic field can be controlled at will by the magnetic field device.

From a scientific point of view, the detachment magnetic field is a kind of field energy, which is harmless to living beings, and can also maintain the temperature in the field well.

The changing magnetic field and the Earth's magnetic field interact with each other, and the energy of the detached magnetic field is determined by the Poynting vector, i.e. = xh/e.

is the Poyinting vector, h is the electric field strength, and e is the earth's magnetic field strength. , h, and e form a right-hand spiral relationship perpendicular to each other, that is, the superionized magnetic energy that represents the unit area perpendicular to it flowing per unit of time, and the unit is /2.

The core material of the X magnetic field device is also very popular, and it is enough to use materials with good magnetic conductivity!

It's mainly a matter of accuracy!

However, the precision requirements are very high, and the material must not be bad, if the material is too poor, it will not be able to process high-precision accessories.

And there are so many materials with good magnetic permeability that Liu Lin doesn't know how to choose them all of a sudden.

Each of them: pure iron and mild steel.

The carbon content is less than 004%, including electromagnetic pure iron, electrolytic iron and carbonyl iron, which is characterized by high saturation magnetization, very low price and good processing performance.

However, the disadvantage is that its resistivity is low, and the eddy current loss is large under the alternating magnetic field, which is only suitable for static use, and is only suitable for the use of electromagnet cores, pole shoes, relays and speaker magnetic conductors, etc., as if it is not suitable for relying on X devices.

The second kind: iron-silicon alloy, silicon content 05% ~ 48%, generally made into thin plates, we call it half-time: called silicon steel sheet.

With the increase of silicon content, the thermal conductivity decreases, the brittleness increases, and the saturation magnetization decreases, but its resistivity and permeability are high, and the coercivity and eddy current losses decrease.

This seems to be okay, but the brittleness problem, I don't know if it will work, wait for the processing to try it!

The third type: iron-silicon-aluminum alloy.

It is obtained by adding silicon to binary iron-aluminum alloy, which has high hardness, saturation magnetic induction strength, permeability and resistivity. The disadvantage is that the magnetic properties are sensitive to the fluctuation of the composition, the brittleness is large, and the processing performance is poor.

Fourth: nickel-iron alloys. Nickel content of 0%~90%, also known as permalloy, through the ratio of alloying elements and appropriate technology, the magnetic properties can be controlled, and soft magnetic materials such as high permeability, constant permeability, and moment magnetism can be obtained. It has high plasticity and is sensitive to stress, and can be used as pulse transformer material, inductor core and functional magnetic material.

The fifth: amorphous soft magnetic alloys. A non-long-range ordered, grainless alloy, also known as metallic glass, or amorphous metal.

It has high permeability and resistivity, low coercivity, insensitive to stress, no magnetocrystalline anisotropy caused by crystal structure, and has the characteristics of corrosion resistance and high strength.

You can also try this one.

Sixth: ultra-microcrystalline soft magnetic alloy.

This is a kind of soft magnetic material discovered in the 80s of the 20th century, which is composed of crystalline phase and amorphous grain boundary phase of less than 50 nanometers, which has better comprehensive properties than crystalline and amorphous alloys, not only high permeability, low coercivity, low iron loss, and high saturation magnetic induction strength and good stability.

This is no problem, there are six kinds, there are four more suitable ones, Liu Lin is ready to process them all and try them.

Okay, wait until you try it!

These are very commonly used materials, just know if there is a stock in the laboratory!

After a while, Liu Ke came and asked him.

Liu Lin put down the materials in his hand and opened the parameter data of the portable thermostat again!

"Boss, H battery was brought over, where do you put it?" Liu Ke knocked on the door, walked in, and saw Liu Lin sitting on the computer and asked.

By the way, Liu Cao, are there any materials with good magnetic conductivity in the laboratory, such as: pure iron and low carbon steel, iron-silicon alloy, silicon amplitude of 05%~48%, amorphous soft magnetic alloy, ultra-microcrystalline soft magnetic alloy, and so on. ”

"Pure iron and low carbon steel warehouses have, 05% ~ 48% iron-silicon alloy and amorphous soft magnet alloy are not, if you want, you have to order. After Liu Ke finished speaking, he glanced at the information on Liu Lin's desktop and asked, "Boss, what do you want to make?"

"Portable thermostat!" Liu Lin said directly without concealment.

"Portable thermostat?" Liu Cao blinked, looking confused, obviously not knowing what a portable thermostat was.

"You know the air conditioner, right?" Liu Lin raised his head, glanced at Liu Ke, and after seeing him nodding, he continued: "It's a miniaturized air conditioner, you can take it with you to go out!"

"How small is that?" Liu Cao opened his mouth, still dizzy, and still couldn't understand it all of a sudden, with the air conditioner, take it out, what's the use, the sun is so big outside, let alone one, even if ten birds are useless!

And energy, how to connect?

With a wireless charger? It's possible.

But the distance is not short, and it doesn't make a big difference!

"It's probably about the same as my mobile phone!" Liu Lin picked up his mobile phone, shook it, and gestured.

"How is that possible?" Liu Ke said in horror as he stuffed his mouth into a fist.

"This is the information, you see, is the X magnetic field device sure to be built?" Liu Lin picked up the information on the desktop and handed it to Liu Cao.

"Beyond the magnetic field, there is such a device?" Liu Ke said in surprise after reading the information.

"Well, how's that?"

"It's so exquisite, it's a genius design, although it's difficult, but it should be fine, maybe it's time, because there are a lot of accessories, this little X-magnetic field device has 56 accessories, each of which is very precise. ”

"There is also a micro circuit is also a problem, but it should be no problem for Luo Xiaowen!" Liu Ke finally put down the information and analyzed.

"I'm going to release this portable thermostat at the Science and Technology City press conference, there can be no product, but a few samples should be fine, right?"

"If a few of us are together, it shouldn't be a big problem!" Liu Ke pondered in his heart!
