Chapter 286 The First Step, Success!

Chapter 286 The first step, success!

The hot summer in City H came a little early this year.

In the past few days, the maximum temperature during the day has reached 35 degrees Celsius.

If things go on like this, wouldn't it be 41 degrees Celsius in July and August?

Song Xuelu is wearing cool cropped trousers, a white T-shirt, white breathable sneakers, a simple necklace without makeup, a small bag in one hand, and a sun hat in the other.

This outfit is simple, elegant and fashionable, highlighting the graceful figure of the goddess, showing a gentle and fresh atmosphere.

This weekend, she is going to go out to deal with charity.

Ma Lan, who was sitting in the living room, saw his daughter-in-law getting ready to go out, and gently reminded her:

"Xuelu, the weather is getting hotter, the highest temperature today is 35 degrees, pay attention to sun protection."

Song Xuelu smiled softly: "Auntie, okay, I have sunscreen on, I'm going first."

Mu Yang, who hadn't left the house yet, walked behind Song Xuelu and grumbled, "Mom, why didn't you ask me if I brought it?"

Ma Lan said disapprovingly, "It's okay for you to get a little tan, it's healthier to be tanned."

"Yes, why don't you look like a boy." Mu Xiaoling, who was sitting at the dining table eating breakfast, complained.

Seeing his sister eating breakfast, Mu Yang babbled, "It's almost 8:30, you wake up so late, how are you doing?"

"..."

Mu Xiaoling didn't want to talk for a moment, and lowered his head to eat breakfast, muttering in his little mouth: Will you chat, and don't keep mentioning your grades, okay?

The whole family can go out to play on Wuyi, but she needs to stay in school to make up lessons. There are only fifty days until the college entrance examination, let's end it early.

Song Xuelu greeted Mu Xiaoling and came to the gate of the villa. At this moment, a black Mercedes-Benz S500L was waiting for her at the gate.

The female bodyguard opened the back door for her, and another female bodyguard was responsible for driving.

Now Mu Yang's family will be accompanied by bodyguards when they go out, so be careful, there is no big mistake, if something happens, there is no medicine for regret.

For the matter of his family's bodyguard, Mu Yang worried a lot.

The family members are all professional bodyguards.

The few veterans that Mu Yang invited by himself have to go to a formal bodyguard company for professional training in the past few months, especially in the field of assault defense response. He has very strict requirements.

If the enemy really wants to hurt the protection personnel, the reaction time left for the bodyguard personnel is only a few tenths of a second, and protective measures must be taken in time.

In addition to the bodyguards, Mu Yang and his family also have to conduct training in this area from time to time, how to protect themselves faster when something unexpected happens.

Mu Yang recalled the event that shocked the world in 2022. If the boss did not turn his head when he heard the gunshot, but immediately squatted down or even hugged his head, it might be fine. Sometimes, the bodyguards would be distracted. Response is not that fast.

When Mu Yang saw Song Xuelu leave, he sat at home for a while, drank a cup of hot milk, and then left too.

The weather is hot, and he wants to patrol the workshop.

The company distributes Huoxiang Zhengqi water to workshop workers. Although the supply is unlimited, it cannot be received in large quantities.

Some people are quite strange, drink this as wine, and drink dozens of bottles. The workshop is not allowed to work while drinking, so at noon, the cafeteria is not open for beer supply, but drinks are open for supply.

Some workers like to drink while eating, and they can still go to work without getting drunk after drinking half a catty of liquor, but this is not allowed in Xinghai Group.

...

Xinghai Group, headquarters base.

In the sixth class of mechanical engineering in the junior year of the Industrial University, the whole class of Mu Yang was doing an internship in the machining workshop.

These students, they have to help the master work, and the master will teach them to simply operate the machine tool in their free time.

But Xinghai Group is busy with production, so the master can only teach when it does not affect production.

The equipment of Xinghai Group is very advanced. Most of these students will work in Xinghai Group after graduation. This is also the reason why Mu Yang asked his classmates to come to the company for internship. He requires each student to be familiar with the basic operation of at least one piece of equipment, measure the product by himself and Draw it and understand its machining process. The learning period is two weeks. After learning, the school will have a real metalworking internship task.

As for the students in other classes, they don't enjoy the treatment of operating equipment in Xinghai Group. At most, they can only observe, and the observation will end after a day or two.

Industrial universities have special practice bases, such as turning, milling and planing grinders. According to the practice plan of previous years, each student must learn to operate a lathe, use pliers and saws, and process a screw-connected hammer, that is, a lathe hammer handle + fitter Hammer head, except that some dimensions meet the requirements, the other shape can be DIY freely. After making it, you can keep it for yourself as a souvenir, and you can use it to smash walnuts in the dormitory.

Through internships, these students can understand how big the gap between reality and ideals is.

Machining is only one of the practical contents, the learning period is generally one week, and there are other practical contents.

Today, they have finished their study tasks for the day and are preparing to leave in a team.

Suddenly, the students in the class saw a familiar figure.

"Hey, everyone, look, isn't that Boss Mu?"

"Well, yes, I guess I'm off to patrol the workshop, I haven't seen him for a long time, I don't know what he's up to. Fatty, do you know?"

"I don't know, I didn't ask, I'm just busy anyway." Mu Yang's roommate Fatty shook his head.

"Xinghai Group is developing too fast. Think about it when you were a freshman, Boss Mu only started to build the company. I remember coming here to help clean up."

"Haha, yes, I asked you to come here, and it costs tens of dollars per person." The fat man still remembered, "Xinghai Group is developing rapidly, and when we come back next year, the Xinghai Building has already been built."

In the machining workshop, they saw the current domestic advanced machining equipment and automated machining lines. The master workers said that in other large factories, they have never seen such an advanced machining workshop with such a good 5S management.

After finishing speaking, the fat man said, "Hey, I can't help it, Mu Yang is too good!"

"Yes, even if he doesn't mix in the business world, even if he has no background, he can become a civil servant. With his appearance, if he is a female leader, as long as he is willing to sacrifice his appearance, he will be in the position very quickly." Li Ming said seriously.

Luo Xiaomin smiled evilly: "Haha, what if his female leader is in her fifties and has no needs for a certain aspect, then Yangzi may not be able to handle it."

Li Ming waved his index finger: "What do you know, Xie Yao is like a wolf at 30, like a tiger at 40, and can suck dirt when sitting on the ground at 50."

Fatty saw the two roommates teasing Mu Yang, and smiled lightly: "You are teasing Boss Mu in his territory, be careful that he hears."

"No, he is still more than ten meters away from us."

"Yes, I've already recorded it." The fat man raised his phone and smiled.

"Fuck, fat man, you are so insidious, delete it quickly, if I can't get into the Xinghai Group after graduation, it must be your problem." Li Ming and Luo Xiaomin knew that the fat man was joking, but what if Mu Yang really cared about it.

"Two hot pot meals."

"Come on, fat man, are you threatening us?"

"Three meals?"

"Only two meals, we will choose the place."

Thus, the "deal" between the fat man and the two roommates was settled.

In fact, he didn't record it.

Mu Yang also saw the classmates in the class, came over to say hello to them and left.

In order to produce and sell wearable air conditioners, Mu Yang specially established Xinghai Outdoor Equipment Co., Ltd. and formed a research and development team of 20 people, which is responsible for the verification and subsequent research and development of new basic models.

For each R&D project team of Xinghai Group, the basic model is provided by Muyang. The R&D team first understands the technology, verifies and develops samples, mass production, and the R&D, optimization and innovation of other styles. Muyang will no longer participate.

The wearable air conditioner project has seven people registered, and the team leader has already registered and can start work. Mu Yang held a meeting and handed over the materials to the project team, demanding that mass production be realized before July this year.

If you miss this summer, you can only wait until next summer.

So, time is tight.

A few days later, Mu Yang opened his mailbox and found that the editors of the two conjecture papers he had submitted had replied to him, indicating that the manuscripts had been urgently sent to review experts, and they were currently under review. Wait patiently.

Submitting a paper to multiple journals is an act of submitting multiple manuscripts, which is expressly prohibited in academia.

However, if the newspaper office has not received a notice to publish the manuscript within 15 days from the date of publication, or the periodical office has not received a notice to publish the manuscript within 30 days from the date of publication, the same work may be submitted to other newspapers or periodical offices. Contribute.

After receiving the review information, no manuscript was rejected, and a preliminary communication was made with the responsible editor.

The editor-in-charge is also a bigwig in the mathematics field, saying that the thesis is not a big problem, but the process still needs to be followed, and Mu Yang knew that the first step was successful.

The next step is to wait for the review by the math boss.

This time is relatively long. Moreover, the two magazines are bimonthly, and generally the fastest publication will have to wait until the next issue is published, which is at least two months.

Of course, if it is an emergency situation, that is, when encountering such things as conjectures, it will be published urgently in the current publication.

The editor-in-charge knew the author's information, so he checked Muyang's background seriously, and he was surprised that he was a young rich man and an inventive genius.

If Mu Yang can really prove the conjecture, the mathematics world will be very lively this year.

In the next ten days, Mu Yang focused on tracking the wearable air conditioner project.

Wearable air conditioners have two key components.

The first key component is a semiconductor cooling chip, which is not expensive and is available on the market.

According to the size of the voltage and power, the voltage of the general miniature semiconductor refrigerator is 3V, 3.7V, 5V, and the power ranges from 1W to 10W.

The size of the low-power semiconductor cooling chip is not large. The common length and width in the market are 40*40mm. The thin piece is extremely light in weight.

Muyang's wearable air conditioner will use a 3.7V semiconductor cooling chip with a power of 3W.

This will be independently developed by Xinghai Group. The technology level can reach the world's top level, and the energy consumption is lower. According to the technical introduction, the power is better than the cooling effect of 6W semiconductor refrigeration chips.

It cools down quickly, but it will not go below zero, which is the main reason for the extremely low energy consumption. If the local temperature is too low, the human body cannot bear it.

The second key component is a rechargeable compressed lithium battery, which is no different from a mobile phone lithium battery. The main cost and weight of a wearable air conditioner is on it.

The price of mobile phone lithium batteries varies greatly. As far as the battery capacity is 3000 mAh, the current market price ranges from 20 yuan to 200 yuan according to different brands.

As for the weight of lithium batteries, mobile phone batteries with large capacity must be heavier, and those with small capacity should be lighter. Currently, the mainstream 3000 mAh battery is about tens of grams, and the better ones are lighter.

Others, such as the shell of the wearable air conditioner, use a plastic shell, which is not worth much money and has little weight.

The production cost of a vest is also extremely low. In the final analysis, it mainly depends on the material of the clothes.

If the manufacturer mass-produces semiconductor refrigeration chips and batteries, the production cost can be kept very low.

Well, there might be a problem.

Can this lithium battery supply the electricity consumed by a semiconductor refrigerator?

the answer is:

no problem!

This has to be calculated from the usage time of the battery capacity.

At present, the battery capacity of mobile phones is mostly between 2500-4500mAh.

mAh is the unit of battery capacity, 1mAh = 0.001 ampere * 3600 seconds = 3.6 ampere seconds = 3.6 coulombs.

The most direct calculation method:

1. Get the current of the electrical equipment first.

2. Divide the battery capacity by the current of the electrical equipment, and the result is the usable time.

For example:

A 3000mAH battery with a rated voltage of 3.7V supplies power to an electrical device with a power consumption of 3W and a voltage of 3.7V. Its theoretical use time is:

I=P/U =3W/3.7V= 0.810A =810mA

h=3000mAH/810mA=3.7 hours

[Remarks: The nominal voltage of lithium batteries in general mobile phones is 3.7V, the fully charged voltage is 4.2V, and the limited charging voltage is 5.0v]

A set of wearable air conditioners has two semiconductor refrigeration chips in the front and rear. The design plus quick-drying clothes does not exceed 280 grams. The required use time is about 3 hours, which is achievable.

As for production costs, as long as the quantity is large enough, all costs will be extremely low after being evenly distributed.

If the sales volume is not large, you can only sell 10,000 to 20,000 pieces a year, and the price of one piece of thousands of dollars may not be profitable.

Later generations of Suoni wearable air conditioners sold in average, with premium brands and good quality clothes, and they were still sold in island countries, which is why they were so expensive.

When DVDs first came out, the price of each set was tens of thousands of yuan, but now it is about two hundred yuan.

Big Brother, which sold for tens of thousands of dollars at the beginning, is produced with the current technology and process, and the upstream materials are cheaper, so the production cost may be only a few tens of dollars.

For electronic products, after the production volume is large, the production cost can be reduced to extremely low.

Originally, the production cost of the most basic version of the wearable air conditioner designed by Muyang was 130 yuan. After the purchasing department consulted the prices of various manufacturers, the actual production cost will be higher, which may reach about 160 yuan, and the overall cost will reach 190 yuan.

Then, the original sales will be lower.

However, if the annual sales volume is more than 5 million units, the price of semiconductor cooling chips and lithium batteries will also drop in a year or two, and the production cost of the basic version of the wearable air conditioner can also be reduced to 130 yuan.

By the end of May, the research and development personnel of the wearable air conditioner project team had arrived, and the project research and development officially entered the state of sample manufacturing.

This wearable air conditioner is not complicated. The lithium battery, plastic exterior, and clothes are all purchased and customized, and Xinghai Group does not need to produce it by itself.

As the core technology, the semiconductor refrigeration chip is manufactured by Xinghai Group, and it is arranged in the No. 5 steel structure workshop of the headquarters base. This workshop is also named "outdoor equipment production workshop".

The research and development of wearable air conditioners is progressing more and more smoothly. It is estimated that the samples will be manufactured in a few days.
