The rise of nanometers

Ms. Dong was very surprised by the scientific research strength of Suiren Company. Although the refrigeration energy efficiency ratio of the new thermoelectric materials is slightly weaker than that of compressor refrigeration, the other advantages of thermoelectric materials can win back a lot of points.

On the exhibition stand, Chang Fuguo introduced the performance of new thermoelectric materials eloquently. He also invited several industry insiders to come on stage to test the efficiency of the thermoelectric power generation system.

Xiang Wenbo was invited to the stage, along with an engineer from Haier and a technical director from Gree.

They wrapped the thermoelectric power generation module on the side of a briquette stove, then ignited the briquettes and connected it to the ammeter of the thermoelectric power generation module. There was indeed a steady stream of current generated, and then connected it to a row of car light bulbs, and the car lights lit up instantly.

Xiang Wenbo communicated with several special guests for a while, and they all felt deeply shocked. They had just inspected the briquette stove and thermoelectric power generation module with their own hands. Obviously, the data in front of them was real.

According to their rough estimate, the efficiency of this thermoelectric power generation module definitely exceeds 20%. The specific power generation efficiency needs to be carefully tested, but generally it will not differ too much.

"Mr. Chang, congratulations on developing another epoch-making product." Xiang Wenbo congratulated enviously.

Chang Fuguo smiled and shook hands with the other party: "I am happy that your engineering vehicles can also consider installing thermoelectric power generation. Even if there are no solar panels, if it is a hybrid, it will still save 50% of energy."

"We will consider it carefully." Xiang Wenbo was indeed very moved.

For engineering vehicles with amazing fuel consumption, 50% of fuel can be saved. Many engineering teams and engineering companies that purchase them will be very happy because this will directly reduce operating costs.

The car companies that came to participate in this expo have also become active. According to the data released by Chang Fuguo, they can already foresee the future.

Even pure electric vehicles are actually not very environmentally friendly, because electric vehicles require power plants to produce electricity, and this process also produces pollution. In addition, battery pollution from electric vehicles is also a problem.

Unless controllable nuclear fusion technology matures and can generate large-scale, low-cost electricity, electric vehicles may not be truly environmentally friendly.

The efficiency of thermoelectric power generation has increased from the previous 6 to 8% to 24%, which is basically a qualitative change.

The improvement of efficiency is the real energy saving and environmental protection.

If you just change the type of energy, the pollution will just change into another form, and it will still exist in another form.

Just like environmental protection in developed countries, it is just packaging and transporting garbage that is difficult to recycle to backward areas. Is this true environmental protection?

If this is truly environmentally friendly, wouldn't it be more environmentally friendly if the Japanese discharge nuclear wastewater into the Pacific Ocean?

True environmental protection is the improvement of energy and material utilization. Just like what Suiren Company does, it is true environmental protection.

After Chang Fuguo went down, it was the turn of Zhang Weixin of Dragon Totem.

The product he introduced is a composite solar panel.

"As we all know, the current photoelectric conversion efficiency of polysilicon solar panels is only 12%, while the efficiency of monocrystalline silicon is 15-24%. The best gallium arsenide solar panels can reach 30% efficiency."

Zhang Weixin changed his words: "The photovoltaic and photothermal composite power generation systems currently being developed by many scientific research teams also face huge limitations in terms of solar energy utilization, and it is difficult for the comprehensive efficiency to exceed the 35% limit."

He looked around at the audience and business representatives, touched the solar panel on the exhibition stand, and introduced with a smile: "The composite solar panel developed by our company has increased the solar energy conversion efficiency to an unprecedented 28% + 24 %."

What?

28%+24%! ?

Everyone was stunned.

"As our chairman said, technology will never end. I will lead everyone to understand the true face of this cross-era technology."

"This product combines thermoelectric power generation, nano molten salt insulation, and silicon nano photovoltaic panels."

Composite solar panels are divided into three layers.

The first layer is a silicon nano photovoltaic panel, which uses photovoltaic power generation mode and converts 28% of the energy in the solar energy into electrical energy.

The second layer of nano molten salt layer is composed of nano chromium salt particles with excellent heat absorption. This material not only has a good heat absorption effect, but also does not reflect light. The overall appearance is dark black and can absorb the light and heat of solar energy. Preserved in a layer of molten salt.

The third layer is the thermoelectric power generation layer, which uses the heat stored in the molten salt layer to generate thermoelectric power. The power generation efficiency is 24%.

In fact, the conversion efficiency of 52% is a wrong statement. However, without transformed data, the real efficiency should be 28% + 55% × 24% = 41.2%.

Because after the solar energy passes through the photovoltaic layer, only 72% of the energy is left. Only about 55% of this energy is stored in the molten salt layer in the form of heat storage, and is finally used by the thermoelectric power generation layer.

So Zhang Weixin said 28% + 24%.

"Our composite solar panels have a comprehensive energy conversion efficiency of 41.2%, and they do not have the complex systems of traditional composite solar power generation systems. The usage is similar to ordinary photovoltaic panels."

After Zhang Weixin's introduction, many people understood the technical principles. Although many scientific research teams have engaged in photovoltaic photothermal composite, there is really no way to compare it with the technology of Suiren Company.

After all, the photothermal power generation system needs to focus solar energy or use a gas generator system to assist, and the power generation system is quite bulky.

The technology required to combine photovoltaic and thermal energy on a board is absolutely beyond imagination.

Zhu Fu below was surrounded by representatives from several other car companies.

Wang Zhegui, the general manager of Shaanxi Automobile, leaned on his seat and asked eagerly: "Lao Zhu, you Dongfeng are unreasonable! You didn't even inform me."

"Isn't it because the technology is immature and Dongfeng will shoulder the risk?" Zhu Fu replied with a smile.

fart! Is the technology immature? Wang Zhegui and other car company representatives secretly cursed, if this technology is not mature yet, what technology is mature?

It is clear that Dongfeng wants to take the lead and use the thermoelectric power generation system and composite solar panels to quickly launch its own hybrid model before other companies can react.

Representatives of various car companies made up their minds and planned to report to the headquarters immediately and quickly follow up on hybrid vehicles.

After Zhang Weixin introduced the composite solar panels, he introduced several special chips launched by Long Totem Company.

"Our Dragon Totem Company has officially released three special chips, namely a high-temperature temperature control chip, a low-temperature control chip, and a brightness control chip. If you are interested in cooperating with any company, you can consult the Dragon Totem exhibition area. "

High temperature temperature control chips are used in kitchen appliances such as ovens and rice cookers; low temperature temperature control chips are used in refrigerators, air conditioners, car air conditioners, etc.; brightness control chips are naturally used for lighting control.

Many companies have obtained detailed performance tables and price lists. The Internet of Things concept promoted by Suiren Company is still in its infancy in China. Although there are related projects abroad, they have not been promoted on a large scale.

Huawei, ZTE, Ziguang and other companies participating in the expo also lamented that Suiren Company has moved quickly and has begun to promote new chips.

After the new product launch conference, all exhibition areas were crowded.
