Chapter 1089 Solving the problem
"What about these holes on top? Do we need to smash them open~!"

From the moment he saw Li Feng's thoughts, Director Kang noticed Chief Engineer Shen's expression.

He didn't understand what the air pressure difference in a building was. He was just a person in charge of production.

Li Feng is still too young, and he is not a college student majoring in mechanics or architecture. He is still a little worried about the big fuss in the factory.

If we talk about the professional and older person on the scene, it’s Shen Jia Shi. If Chief Engineer Shen thinks it’s okay, then there will definitely be no problem.

The shutdown caused by high temperature is the pain of the workshop in summer. If it can be solved, it will be more comfortable for him to stay here.

"Smash it! We have to smash it. Hot air rises. This is a scientific law. What's below is below. If the structure on the roof is not changed, the hot air can't be discharged. It will accumulate from morning to afternoon, and the quantitative change will lead to qualitative change~!"

Looking at the white circles drawn with talcum pen, Li Feng already had a preliminary idea: the idea of ​​expelling the heat without using electricity or opening the windows.

Unpowered wind ball.

Developers usually install a small stainless steel ball just above the chimney of a residential building, which sparkles brightly under the sun.

The side of the wind ball is made of stainless steel sheets that are bent and stacked together to form semi-spherical fan blades. With a slight push, the gadget can rotate. Its appearance looks a bit like a watermelon worm that curls up into a ball after being frightened.

It does not rely on electricity at all, but purely relies on the internal air pressure difference, or the natural wind from the outside to naturally discharge the internal hot air flow through rotation.

Waterproof, simple and effective. Li Feng remembers that in many factories with blue iron sheds, many of these gadgets would be installed on the top in order to save cooling costs.

In today's world where technological progress is not advanced enough, let alone air conditioners, even electric fans are rare commodities. Although this little ball is small, it is undoubtedly very useful. Even if it is made of tin, it will not be a big problem if it can be used for a while.

"Let's go down first and ask the transportation department to send a car to the construction site to pick up two people who understand construction. The holes can't be dug to the point where they affect the load-bearing capacity. Let them check that it doesn't affect the structure of the house, and then we can send people to demolish it first~!"

Li Feng patted the powder on the talcum pen in his hand and already had a plan in mind. With the exhaust fan below and the wind ball above, at least the temperature inside the workshop would not be higher than outside the workshop.

The hot air is expelled and the cold air containing moisture comes in, and that is when the electric fan provided really starts to work.

Once the experimental results are established, the working environment during the high temperature period in summer will be effectively improved, and production efficiency will definitely increase. The annual output of each workshop can be increased by at least 10%-15%!

The most important thing about this scientific method is that it requires no technical content and can be easily promoted.

This is also the reason why Li Feng, even if he has to take the blame today, has to withstand the pressure from everyone and work in the factory. He wants to submit an answer sheet to the relevant superior departments in advance for the workers and for himself after returning from his studies.

What's wrong with being young? As long as you are willing to work hard, you can still get through that hurdle. Looking at the whole country, the importance of a 10% increase in output to industrial modernization is naturally self-evident.

One by one, they climbed down the ladder from the upper entrance. A group of middle-aged leaders, after being exposed to the sun for such a long time, felt a little weak, but seeing Li Feng's high morale, they had no choice but to bite the bullet and follow.

"This time, in response to the high temperature environment in the factory, our Red Star Steel Rolling Mill has launched a major campaign to reduce the temperature in the workshop and must reduce the temperature to an appropriate level~!"

"Notify the Materials Department to extract the motors in stock. As long as they can run when connected to electricity, find a way to get me seven, eight, nine, or nine motors. Also, get me a few more matching transmission belts~!"

Li Feng counted the open windows on the west side and gave instructions to the secretary who accompanied him.

He picked up a screwdriver from the shelf and began to dismantle the iron frame outside the fan. After removing the fan blades, he looked at the style and continued to arrange it.

"Don't go yet. There are still some fan blades. Ask the forging workshop to measure the size of the window and make it smaller than the window frame. In the welding workshop, Director Kang will send someone to weld a bearing in the middle of it, and finally connect it with a belt and fix it to the window frame. The motor must be able to drive the fan blades when it is powered on~!"

"Also, have the fitter shop drill holes for the water pipes, and the maintenance department will be responsible for sending workers to connect the water pipes so that after the valves are opened, water can drip down and be installed under the west window~!"

"Yes~!"

Orders were given one by one. Fortunately, basically all kinds of workers could be found in the steel rolling mill, and the relevant materials could be processed by machines. There was also a team of plumbers and electricians responsible for electrical installation.

What Li Feng had to do was to direct everyone and arrange what they should do and how to do it in an orderly manner. That was not the end. After the windows on both sides of the workshop were arranged, there was also the unpowered wind ball on top. Although that thing was simple, Li Feng still needed professionals to design it.

"Tin sheet, find me a piece of tin sheet and cut it longer. Bring me the scissors for cutting~!"

"Yes~!"

The workers who were standing outside the workshop to enjoy the cool air had more or less calmed down by now. They stood at the door of the workshop, watching the cadres, under the command of Deputy Director Li, getting busy in the workshop.

People come in and out from time to time, such as the blacksmith holding the fan blades and the fitter holding the water pipes. After they go in, they will soon leave with their butts burned.

Although no one knew what he was busy with, we all guessed that he was trying to find a solution to the high temperature environment in the workshop.

"It's still Deputy Secretary Li. He's the only one who cares about us~!"

"Whether the temperature can be lowered or not, the fact that he actually did it proves that he cares about us. I, Lao Gu, admire him from the bottom of my heart~!"

The welders didn't know what was going on inside, but they could see that Li Feng, who was soaked all over, did not move out of the workshop. He was giving orders inside from beginning to end, with red eyes.

"The fan blades don't have to be processed into special shapes like this. The fan blades can be flat and long, but when connecting in the middle, the angle must be slightly tilted, forty-five degrees is also OK. After symmetrical welding, it can still play the role of fan blades~!"

On the table, Li Feng was not only drawing the appearance of an unpowered wind ball, but also, after hearing that the forging master had difficulty processing special shapes, he immediately drew another type of inclined straight-shaped fan blade.

What we need now is speed. The processing of special-shaped fan blades requires the use of a press and a mold, but exhaust fans cannot use such fan blades.

Helicopter propellers are flat, but the reason they can take off and land is because the connection can rotate the tilt angle of the blades. The exhaust fan does not need to be that complicated, it can just be fixed with a 45-degree angle weld.

"What is this thing?"

After the blacksmith finished giving the instructions, Chief Engineer Shen looked at the wind ball drawn by Li Feng on the table and fell into deep thought. He couldn't understand it, let alone others.

"After cutting the tin sheet, bend it like this. As long as there is a support point in the middle to allow it to rotate, whether it is the wind from the outside or the rising air pressure inside, it can transmit the heat gathered above. It works on the same principle as an electric fan~!"

"However, it does not require electricity, it can do this job purely by rotating itself~!"

Li Feng took a pair of big scissors, measured the size, and cut them one by one. After he demonstrated how to bend them and asked the welder to weld them, an extremely simple wind ball was finally completed.

The wind ball didn't have enough blades and its shape was a bit rough, but when Li Feng put his fingers inside and gently pushed it, allowing the wind ball to rotate on its own on his fingertips, Chief Engineer Shen's eyes lit up visibly.

"Ouch~!"

"Is this what you were thinking?"

"We didn't even think of such a simple thing?"

After the demonstration, he immediately figured out the principle. Chief Engineer Shen and other technicians looked at Li Feng with different eyes. Ordinary people could never have thought of this.

Everyone couldn't let it go and touched the tin wind ball in the deputy factory director's hand with their own hands, while the other ignorant people stared with their eyes wide open, still not understanding how this thing worked.

"It needs a support point inside to keep it rotating. The fan blades need to be more numerous and denser so that they can keep out rain. The fixed base also needs to be waterproof!"

Wiping the sweat off his forehead, Li Feng simply designed the exterior and threw the rest to Chief Engineer Shen. If his technicians couldn't do this well, then they would be done for.

After an afternoon of suspension, as the simple exhaust fan began to rotate driven by the motor and belt, accompanied by a buzzing sound, the surge of air inside the workshop could be clearly felt.

Especially when standing outside the window, the hot air brought out by the exhaust fan is so strong that people can't open their eyes. After the water curtain starts dripping, the temperature at the bottom of the workshop can be clearly felt to change.

Applause, applause like a tide. All the workers in the welding workshop took off their gloves, with tears in their eyes, and gave warm applause to their beloved Li Feng, Deputy Director Li.
