Chapter 130: Bladeless turbine

"I can upgrade the shelter ( to find the latest chapter!

The resurgence of old love between old lovers is only an episode after all,

and how to survive is the theme of the current doomsday.

For Chen Xin, he now has no need to worry about how to survive.

The emergence of hot spring water has greatly increased the heat energy that

the ground source heat pump can obtain. Even if Chen Xin turns off the

equipment, the temperature of the refuge can be maintained at about 13-16 ℃

due to the influence of the warming of groundwater.

If it is not necessary to maintain the temperature of the greenhouse, the

ground source heat pump that Chen Xin has just built is even somewhat

redundant.

But this also gave him a new idea, which is to use the heat generated by the

ground source heat pump to generate electricity.

This is technically not difficult to achieve. It is only necessary to connect

a heat recovery device to the heat pipe, and then use the heat to convert

thermal energy and convert it into electrical energy.

As for the means of converting thermal energy into electrical energy, the

steam turbines commonly used in thermal power plants are sufficient to

complete the task.

When it comes to steam turbines, Chen Xin used to be a geek fan for a while

when he was in college. In the dormitory, he used the air-bed blower and waste

discs to transform a Tesla turbine that can really power the light bulb.

Although this thing has no practical meaning at all, it relies solely on the

blower to drive the impeller to rotate and work, but on the whole, the thing

is considered to be made, and it is not complicated to make it. Chen Xin’s

computer is now And the drawings he used at the time.

The Tesla turbine is a turbine invented by the legendary federal physicist

Nikola Tesla.

The efficiency of this kind of turbine is much higher than that of the

traditional blade turbine. Nikola Tesla once dreamed of using it to generate

electricity from geothermal heat.

Of course, although this technology looks very beautiful, it is still

restricted by many conditions in practical applications, so that this

technology has been invented by Nikola Tesla for more than a hundred years,

and practical applications are still very few.

The main reason that restricts the promotion and application of this

technology is that the internal rotor must be thin enough and smooth enough

disks to be arranged in a dense enough manner to form a large enough rotor, so

that the rotor can pass the fluid through the rotor. Drive the rotor to rotate

at a high speed under the action of the boundary layer effect.

This undoubtedly places extremely high requirements on the material used to

make the disc, which must be both light and strong.

And a big problem with bladeless turbines is that the greater the load, the

lower the efficiency, and in order to achieve a sufficiently high speed, the

fluid flow through the rotor must be as small as possible.

But this is not a problem for Chen Xin.

With the help of the system, the production of the rotor is not a problem at

all, and what Chen Xin needs is a small generator that can meet the

electricity needs of his refuge, neither the load nor the fluid flow is too

big.

"Axin, what are you doing?" Qin Lan couldn't help feeling very curious as he

watched Chen Xin continuously process a piece of metal material on the

workbench into thin circular metal pieces.

"Being a turbine, I plan to use the surplus heat of the ground source heat

pump to generate electricity. This requires a turbine." Hearing Qin Lan's

inquiry, Chen Xin explained to her and did not stop his work.

Chen Xin is not actually processing these round metal sheets by himself, but

in Qin Lan's eyes, Chen Xin is processing them by himself.

With the help of the system, the metal materials are processed into thin

paper-like metal discs and assembled, and then the main shaft is installed in

the middle, and the rotor of the bladeless turbine is finished.

Qin Lan looked at Chen Xin's serious work, and did not disturb him, but leaned

against Chen Xin's workbench and watched him work quietly.

There is a saying that men who work hard are the most handsome, and the

expression Qin Lan looks at Chen Xin at this time undoubtedly confirms this

sentence.

However, Chen Xin didn't notice the infatuation in Qin Lan's eyes when he saw

him. He just installed the assembled rotor into the volute.

After assembling the casing of the entire turbine, after checking that there

was no problem, Chen Xin turned the rotor by hand again, and confirmed that

the rotor was operating normally by manual turning, and then the entire volute

was connected to the gearbox.

Although the speed of the bladeless turbine is high, the torque is not large.

If you want to obtain sufficient output power, it is necessary to reduce the

speed with a gearbox to increase the torque of the drive shaft.

This is not a complicated process. A set of planetary gears can solve the

problem.

As for the generator part, it is even simpler. Even junior high school

students understand the principle of cutting the magnetic induction line to

generate electricity.

After all the parts are assembled and a generator connected to a bladeless

turbine is completed, the next step is naturally installation.

"Alan, help me carry it." The finished generator was a little heavy, and Chen

Xin had to ask Qin Lan to help.

The two carried the generator to the side of the ground source heat

pump~www.mtlnovel.com~ and put down the generator. Qin Lan asked curiously:

"Where should this be installed?"

"Just connect the pipe to the condenser. The airflow in the pipe can absorb

the heat emitted by the condenser when passing through the condenser, so that

the volume of the air expands, forming a high-speed airflow to drive the rotor

of the turbine to rotate." Chen Xin After an explanation, he opened the system

interface and chose to consume survival points to install equipment.

The system installation is much more convenient and quicker than Chen Xin’s

manual installation. He even helped him with the wiring and connected the

generator to the power distribution room.

As Chen Xin adjusted the output power of the ground source heat pump, and at

the same time turned on the switch of the turbine, the generator also started

running.

"It's really moving!" Seeing that the turbines and generators that were

connected to the condenser by Chen Xin were moving, Qin Lan couldn't help but

exclaimed, "Axin, you are so amazing!"

"Anyone who knows a little about mechanical processing and physics can make

this, it's nothing great." Chen Xin shook his head, and didn't feel proud of

Qin Lan's praise: "If it weren't for the hot springs underground that caused

the ground temperature to rise, this set The power generation of the system is

enough to maintain the ground source heat pump equipment running by itself.

But now that the ground temperature rises, the excess heat energy can be

converted into more electricity. As long as the power of the generator is

larger, it should be able to maintain my electricity consumption here.

I am only worried that the groundwater temperature rise is temporary. When the

ruptured groundwater layer is blocked again, if the low temperature drops..."

At this point, Chen Xin couldn't help showing a worried expression.

"Axin, you are too pessimistic, think better, maybe this is permanent? You

will have hot springs in the future." Qin Lan laughed and encouraged Chen Xin

with a smile, hoping that he would be more optimistic.
