Doomsday Bunker Upgrade Chapter 129: 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 this doomsday now.

For Chen Xin, he can no longer worry about how to survive.

The appearance of hot spring water has greatly increased the heat energy that can be obtained by the ground source heat pump. Even if Chen Xin turned off the equipment, the temperature in the shelter could be maintained at about 13~16℃ due to the influence of the temperature of the 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 not difficult to achieve technically, just need to connect a heat recovery device to the heat pipe, and then use the heat for thermal energy conversion and convert it into electricity.

As for the means of converting thermal energy into electrical energy, the steam turbine commonly used in thermal power plants is 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 air bed blowers and used discs to transform a Tesla turbine that can really power the light bulb. .

Although this thing has no practical meaning at all, it relies entirely 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 There are still drawings he used at the time in the computer.

The Tesla turbine is a turbine invented by legendary federal physicist Nikola Tesla.

Much more efficient than traditional bladed turbines, the turbines Nikola Tesla dreamed of using geothermal power to generate electricity.

Of course, although this technology looks beautiful, it is still constrained by many conditions in practical application, so that this technology has been invented by Nikola Tesla for more than 100 years, and its practical application is still Very few.

The main reason for restricting the promotion and application of this technology is that the internal rotor must be thin enough, and the surface of the smooth enough discs are arranged in a dense enough manner to form a large enough rotor, so that the rotor can pass through The fluid in the rotor drives the rotor to rotate at high speed under the action of the boundary layer effect.

This undoubtedly places extremely high demands 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 higher the load, the lower the efficiency, and in order to achieve a high enough 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 himself 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 but be very curious as he watched Chen Xin process a piece of metal material into thin circular metal sheets on the workbench.

"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 at the same time, he did not stop his work.

Chen Xin is not actually processing these circular 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 material is 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 completed.

Qin Lan looked at Chen Xin's serious work and did not disturb him, but just 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 Qin Lan's gaze at Chen Xin at this time undoubtedly confirms this sentence.

However, Chen Xin didn't notice that Qin Lan's eyes were full of infatuation, he just put the assembled rotor into the volute.

Assembled the casing of the entire turbine, and 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. In order to obtain sufficient output power, it is necessary to reduce the speed with a gearbox to increase the torque of the drive shaft.

It's not a complicated process, a set of planetary gears will do the trick.

As for the generator part, it is even simpler. Even junior high school students understand the principle of cutting magnetic field lines to generate electricity.

After all the parts are assembled and a generator connected to a bladeless turbine is ready, the next step is installation.

"Alan, help me carry it over." The finished generator was a little heavy, so Chen Xin had to ask Qin Lan to help.

The two lifted the generator to the side of the ground source heat pump~IndoMTL.com~ Putting down the generator, Qin Lan asked curiously, "Where is this going to be installed?"

"Just connect the pipe to the condenser. The airflow in the pipe can absorb the heat emitted by the condenser when it passes 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 explained, then 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 own manual installation. He even helped him to walk the line and connect the generator to the power distribution room.

As Chen Xin adjusted the output power of the ground source heat pump and 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 moved, 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 in the ground that caused the ground temperature to rise , the power generation of this system is enough to maintain the ground source heat pump equipment running by itself.

But now that the ground temperature is rising, the excess heat energy can be converted into more electrical energy. As long as the power of the generator is a little bigger, it should be able to maintain my electricity consumption here.

I am only worried that the increase in groundwater temperature is temporary, and when the ruptured groundwater layer is blocked again, if the temperature drops..."

Speaking of this, 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, encouraging Chen Xin with a smile, hoping that he Be optimistic.
