v2 Chapter 285： Step 1, it worked!
The hot summer in H City came a little early this year.
In the past few days, the highest temperature during the day has reached 35 degrees Celsius.
At this rate, wouldn't it be 41 degrees Celsius in July and August?
Song Xuelu is wearing cool cropped pants, 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 dress is simple, elegant, fashionable and avant-garde, highlighting the graceful figure of the goddess and showing a gentle and fresh atmosphere.
This weekend, she's getting ready to go out for charity.
Ma Lan, who was sitting in the living room, saw her daughter-in-law preparing to go out, and gently reminded:
"Xuelu, the weather is getting hot, the highest temperature today is 35 degrees, pay attention to sun protection."
Song Xuelu smiled gently: "Auntie, okay, I have sunscreen, I'll go first."
Mu Yang, who had not yet gone out, walked behind Song Xuelu and grunted, "Mom, why didn't you ask me if I brought it?"
Ma Lan said indifferently: "It's fine for you to tan, and tanning looks healthier."
"Yes, don't look like a little white face." Mu Xiaoling, who was sitting at the dining table eating breakfast, complained.
Seeing his sister eating breakfast, Mu Yang said, "It's almost 8:30. How are your three models?"
"…"
Mu Xiaoling didn't want to talk for a moment, bowed her head to eat breakfast, and muttered in her small mouth: Can you chat? Don't keep talking about whether your grades are good.
On May 1, the whole family can go out to play, but she needs to stay at school to make up lessons. The college entrance examination is only 50 days away, so let's end it early.
Song Xuelu greeted Mu Xiaoling and came to the gate of the villa. At this time, 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 in charge of driving.
Now Muyang's family will be followed by bodyguards when they go out, so be careful, and if something goes wrong, there is no regret.
For the family's bodyguard, Mu Yang worried a lot.
The family are professional bodyguards.
The veterans that Mu Yang hired by himself have to go to the official bodyguard company for professional training in the past few months, especially in the area of assault protection and response, he is very strict.
If the enemy really wants to hurt the protection personnel, the reaction time left for the bodyguards is only a few tenths of a second, and protective measures must be taken in time.
In addition to bodyguards, Muyang and his family have to conduct training in this area from time to time, how to protect themselves faster when something unexpected happens.
Mu Yang remembered the event that shocked the world in 2022. If the big guy didn't turn his head when he heard the gunshots, but squatted down immediately or even lay down and hugged his head, maybe it's nothing, sometimes the bodyguards will be distracted, The reaction ability is not so fast.
Seeing Song Xuelu leave, Mu Yang sat at home for a while, drank a glass of hot milk, and then left.
The weather is getting hot, and he is going to patrol the workshop.
The company will distribute Huoxiangzhengqi water to workshop workers. Although there is an unlimited supply, it cannot be received in large quantities.
Some people are more strange, and drink this as wine, and they drink dozens of bottles. The workshop is not allowed to drink and work, so at noon, the canteen is not open for beer supply, but beverages are open for supply.
Some workers like to drink while eating, and they won't get drunk even if they drink half a catty of liquor, and they can still go to work, but this is not allowed in Xinghai Group.
…
Xinghai Group, headquarters base.
The third year of the University of Technology, the sixth class of mechanical engineering, Muyang's whole class practiced in the machining workshop.
These students, they have to help the master with the work. In their spare time, the master will teach them to operate the machine tool simply.
But Xinghai Group is busy with production, so the master can only teach it when it does not affect production.
Xinghai Group's equipment is very advanced. Most of these students will come to work in Xinghai Group after graduation. This is why Muyang let the students in the class come to the company for internships. Each student is required to be familiar with the basic operation of at least one piece of equipment, measure the product by himself Draw it and learn about its machining process. The learning cycle is two weeks. After finishing the study, the school has a real metalworking practice task.
As for the students in other classes, they could not enjoy the treatment of operating the equipment in Xinghai Group. At most, they were just observing, and the observation was over in a day or two.
The University of Technology has special practice bases, such as turning, milling, planing and grinding machines. According to the previous year's practice plan, each student must learn to operate a lathe, use pliers and saws, and process a threaded hammer, that is, a turner's hammer handle + fitter Hammer head, except for some of the size requirements, the other shape can be freely DIYed. After it is done, it can be kept as a souvenir and can be used in the dormitory to smash walnuts.
Through the internship, these students can understand how big the gap between reality and ideal is.
Machining is only one of the practical contents, and the learning cycle is generally one week, and there are other practical contents.
Today, they have finished their study tasks for the day and are ready to leave.
Suddenly, the students in the class saw a familiar figure.
"Hey, everyone, look, isn't that Mu Boss?"
"Well, yes, it is estimated that I have been patrolling the workshop. I haven't seen him for a long time. I don't know what I am busy with. Fatty, do you know?"
"I don't know, I didn't ask, I'm busy anyway." Mu Yang's roommate Fatty shook his head.
"Xinghai Group is developing too fast. Thinking about the first year of freshman year, it was only when Mr. Mu started to set up the company. I remember coming over to help with the cleaning."
"Haha, yes, I asked you to come. It costs a few dozen yuan per person." Fatty still remembers it fresh, "Xinghai Group is developing with each passing day. When we come back next year, the Xinghai Building has already been built."
In the machining workshop, they saw various types of advanced domestic machining equipment and automated machining lines. The master worker said that in other large factories, they have never seen such an advanced machining factory where 5s is managed so well.
After speaking, Fatty said, "Hey, no way, Mu Yang is too good!"
"Yes, even if he doesn't belong to the business world, even if he has no background, to become a civil servant, with his appearance, if he is a female leader, as long as he is willing to sacrifice his selves, he will quickly ascend to the top." Li Ming said seriously.
Luo Xiaomin smiled evilly: "Haha, in case his female leader is in her fifties and has no demand in certain areas, then Yoko may not be able to handle it."
Li Ming waved his index finger: "What do you know, the evil waist is like a wolf at thirty, like a tiger at forty, and can **** soil when sitting on the ground at fifty."
Fatty saw that the two roommates were teasing Mu Yang, and smiled lightly: "You are making fun of Boss Mu in other people's territory, be careful he hears."
"No, he is still more than ten meters away from us."
"Yes, I've already recorded it." Fatty raised his phone and laughed.
"Fuck, Fatty, you are so sinister, delete it quickly. If I can't join the Xinghai Group after graduation, it must be your problem." Li Ming and Luo Xiaomin knew that Fatty was joking, but what if Muyang really cares about it.
"Two hot pot meals."
"Lying back, fat man, are you threatening us?"
"The three meals?"
"Just two meals, we choose the location."
So, the "deal" between Fatty and his two roommates was settled.
In fact, he did not record.
Mu Yang also saw the classmates in the class, came over to greet them and left.
In order to produce and sell wearable air conditioners, Muyang established Xinghai Outdoor Equipment Co., Ltd., and set up a 20-person R&D team to be responsible for the verification and follow-up research and development of new basic products.
For each R&D project team of Xinghai Group, the basic models are provided by Muyang. The R&D team first understands the technology, verifies and develops samples, mass production, research and development and optimization of other styles, and innovation. Muyang is no longer involved.
Seven people from the wearable air-conditioning project registered. The team leader has registered and can start work. Muyang held a meeting and handed over the materials to the project team, requesting to achieve mass production before the arrival of July this year.
If you miss this summer, it will only be available until next summer.
So, time is tight.
A few days later, Mu Yang opened his mailbox and found that he had submitted two conjecture papers. The editors in charge of the two magazines had already sent back the manuscripts to him, indicating that the manuscripts had been sent to the review experts in an expedited manner, and he was currently reviewing the manuscripts. Wait patiently.
Submitting a paper to multiple journals is an act of multiple submissions for one manuscript, which is expressly prohibited in academia.
However, if the manuscript is not notified by a newspaper office for publication within 15 days from the date of issuance of the manuscript, or if it is not notified by a journal office for publication within 30 days from the date of issuance of the manuscript, the same work may be submitted to other newspaper offices or periodicals. Contribute.
After receiving the review information, the manuscript was not rejected, and preliminary communication was conducted with the editor in charge.
The editor-in-charge is also a big boss in the mathematics world, and he said that the problem of the paper is not big, but the process still has to be followed, and Mu Yang knows that the first step is successful.
The next step is to wait for the math boss to review.
This time is relatively long, and these two magazines are bimonthly. Generally, the earliest publication will have to wait until the next issue is published, that is, at least two months.
Of course, if it is an unexpected situation, that is, if there is such a thing as conjecture, it will be expedited in the publication that is currently being published.
The editor in charge knew the author's information, and he carefully checked Muyang's background. 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.
For the next ten days, Muyang focused on tracking the wearable air conditioner project.
Wearable air conditioners have two key components.
The first key component is the semiconductor refrigeration chip, which is not expensive and is available in the market.
According to the size of the voltage and power, the voltage of the general micro-semiconductor refrigeration chip is 3v, 3.7v, 5v, and the power is from 1w to 10w.
Low-power semiconductor refrigeration chips are not large in size. The common length and width in the market are 40*40mm.
Muyang's wearable air conditioner will use a 3.7v semiconductor refrigeration chip with a power of 3w.
This will be independently developed by Xinghai Group, the technical 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 the 6w semiconductor refrigeration chip.
It cools down fast, but never below zero, which is the main reason for the extremely low energy consumption. If the local temperature is too low, the human body can not bear it.
The second key component is the rechargeable compressed lithium battery, which is no different from the lithium battery of the mobile phone. The main cost and weight of the wearable air conditioner are on this.
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 a lithium battery, a mobile phone battery with a large capacity must be heavier, and a small capacity battery will be lighter. At present, the mainstream 3000 mAh is about tens of grams, and the better one is lighter.
Others, such as the casing of the wearable air conditioner, use a plastic casing, which is not worth much and does not weigh much.
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 may be a problem.
Can this kind of lithium battery afford the power consumption of a semiconductor refrigeration chip?
the answer is:
no problem!
This has to be counted from the usage time of the battery capacity.
At present, the battery capacity of mobile phones is mostly between 2500-4500mah.
Mah is a unit of battery capacity, 1mah = 0.001 ampere * 3600 seconds = 3.6 ampere seconds = 3.6 coulombs.
The most direct calculation method:
1. First get the current of the electrical equipment.
2. Divide the battery capacity by the current of the electrical equipment, and the result is the usable time.
E.g:
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 usage time is:
i=p/u=3w/3.7v=0.810a=810ma
h=3000mah/810ma=3.7 hours
[Remarks: The nominal voltage of the general mobile phone lithium battery is 3.7v, the full voltage is 4.2v, and the limited charging voltage is 5.0v]
A set of wearable air conditioners consists of two semiconductor refrigerating chips before and after, the design plus quick-drying clothes does not exceed 280 grams, and the required use time is about 3 hours, which is achievable.
As for the production cost, as long as the quantity is large enough, all kinds of costs will be extremely low after being evenly amortized.
If the sales volume is not large, it can only sell 10,000 or 20,000 pieces a year, and it may not be profitable to sell one piece for thousands of yuan.
Later generations of Suomu wearable air conditioners have average sales, brand premiums, and high-quality clothes, and they are still sold in island countries, which is why they are so expensive.
When dvd first came out, the price of each set was tens of thousands of yuan, and now it is about 200 yuan.
Big brother, it was sold for tens of thousands of dollars at the beginning. It is produced with the current technology and craftsmanship. At the same time, the upstream materials are cheap, and the production cost may be only tens of dollars.
For electronic products, after the production volume is large, the production cost can be reduced to a very low level.
Originally, the production cost of the most basic version of the wearable air conditioner designed by Muyang was 130 yuan. After the purchasing department has consulted the prices of various manufacturers, the actual production cost of UUkanshu will be higher, which may reach about 160 yuan. The total cost is 190 yuan.
Then, the original sales were lower.
However, if the annual sales volume is more than 5 million pieces, the price of semiconductor refrigeration 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 were all in place, and the project research and development officially entered the state of sample manufacturing.
This wearable air conditioner is not complicated. Lithium batteries, plastic exteriors, and clothes are all purchased and customized, and Xinghai Group does not need to produce it by itself.
As the core technology of semiconductor refrigeration sheet, it is produced by Xinghai Group and arranged in the No. 5 steel structure workshop of the headquarters base, which is also named "outdoor equipment production workshop".
The research and development of wearable air conditioners is progressing smoothly, and it is estimated that samples can be produced in a few days.
