Hu Wenhai went out to travel, since he came to Shandong, he must go to the nationally renowned 5A-level scenic spot - Jinan Freshwater Seal Breeding Base to have a look. In fact, Shandong is really a very developed province, although Jinan is the provincial capital, it can not represent the highest level of Shandong at all.

Shandong University is known as the first university of the world, one school, three places and eight campuses, Hu Wenhai later met a cashier of the first affiliated hospital of the world on the Internet, his talent is simply jaw-dropping, it can be seen that Shandong is really outstanding people. The name of the universe Shouguang, the world's Weifang, China's Qingdao, Shandong's Dezhou, Zhangqiu's Jinan is really worthy of its name.

And not to mention that Hu Wenhai is barely half a Shandong, after all, the sound of the same province is almost exactly the same as Shandong, which sounds very kind. The generation that broke through the eastern part of the country has gone down to the present, and no one in the Northeast can find a Shandong ancestor.

So when Hu Wenhai returned to Qingdao, he almost had to arrange to use a police car to open the road and enjoy the road closure treatment of high-ranking officials.

The reason is actually simple, some news has finally shown its power after a period of fermentation.

Fluorine-free compressors are indeed a revolutionary technology, but emerging technologies are not always a one-step solution. The absence of freon means that this compressor is bound to be higher than a fluorinated compressor in terms of power and power consumption. In this way, the cost of using fluorine-free compressors has risen, and there are still some advantages to fluorine-free compressors.

However, when Haier advertised to the outside world, it stated that this kind of fluorine-free refrigerator will be more energy-efficient than fluorine-free refrigerators. The occurrence of such a situation that violates the laws of technology will inevitably attract the attention of the industrial and technological industries.

After Whirlpool reached a strategic partnership with Haier, the white power industry around the world had to face up to Haier's fluorine-free technology.

And as soon as I faced it squarely, I immediately discovered the key to it.

Haier's fluorine-free compressor is indeed more advanced, but it is not a black technology. Europe and Japan want to develop a similar fluorine-free compressor, but there are no technical difficulties. However, in terms of energy consumption, it is not up to Haier's level in any way.

Then naturally some people set their sights on another technical feature of Haier refrigerators, that is, inverter technology.

Inverter is not a new technology, but before the eighties, inverter was mainly based on thyristor technology. Household appliances want to use this technology inverter, not only the performance can not meet the use, but also the cost is unacceptable.

In the 70s, a breakthrough was made in the development of inverter technology using the PM-VVVF system, but the switching technology was still unable to be applied to actual products.

And thanks to the use of IGBT technology, the output frequency of PM has directly increased by more than an order of magnitude. In this way, the inverter technology has rapidly moved from laboratory technology to the market.

Until someone discovered the secret of IGBT through the study of the technical data published by Haier. The white goods industry was in an uproar, IGBT's inverter technology is not only used in refrigerators, the application prospects here are too broad!

Microwave ovens, washing machines, induction cookers, rectifiers of all kinds, fans, lights, vacuum cleaners and irons, and even cameras can be used. Wherever the frequency of the power supply needs to be controlled, IGBTs are there.

In fact, GE has long proposed the technical route of IGBT, but it cannot solve the damage to MOS devices caused by electron irradiation. Therefore, the industry is not ignorant of this technology, but an apple that can be seen and temporarily touched.

Although no one knows how the IGBT product adopted by Haier solves the problem of damage to the MOS structure. But when Haier's supplier identity surfaced, everyone no longer doubted it - ST Electronics Research Institute is now a giant in the electronic chip industry, and its words still have weight.

It's just that I'm afraid everyone is regretting that the ingenious solution to the damage of the MOS structure was found by Xinke again?

No, no one would suspect that it was Xinke squeezing toothpaste. If anyone develops such a technical product, they will definitely be eager to put it into the market. The reason is very simple, its technical application prospects are too broad!

When such news spreads in the white goods industry, everyone recovers from the initial sense of blow, and begins to imagine what scenarios and products can be applied. With a little imagination, practitioners in the white power industry will feel their blood pumping.

However, the news of the breakthrough in IGBT technology soon spread beyond the white goods industry.

It was quickly spread to the entire upstream and downstream industries of white electricity, and then quickly began to spread in all related fields.

What does this mean?

IGBT is not only of great significance to the white power industry, it is of great significance to all power equipment!

Or to put it another way, it is of great significance to all aspects of industrial production in modern society!

Wherever its message spreads, there will be an earthquake in the industry.

The white power industry is just the beginning, power network, transportation, transportation, machinery and equipment production, aerospace and defense industry, modern industry is built on power technology, then it can be said that power semiconductors are an indispensable piece of the puzzle of modern industrial foundation. Even if the IGBTs produced by ST can only be used in low-power fields, the global market is tens of billions of dollars.

Ten billion dollars in the early nineties, that's not scary enough?

When the global industry began to pay attention to IGBT, no matter how slow the country was, it knew what a terrible thing it was.

Qingdao, as the largest city in Shandong, has set its sights on this piece of fat.

Hu Wenhai sat in Zhang Ruimin's car, with Lu B00000 in front of him opening the road, and the roadside citizens frequently looked into the car, making him cry and laugh for a while.

"IGBT chips are still being produced in Modu, and Xinke is indeed considering expanding production capacity. ”

Hu Wenhai withdrew his gaze from the outside of the car, thought for a while and said: "It is not a problem to invest in a wafer factory in Qingdao, there have been many domestic investment in wafer factories in recent years, and talent reserve is not a problem. Haier can also get involved if it's interested. ”

That's the way it is, the new technology wafer factory has broken the international technology blockade against China, and the domestic chip manufacturing process is almost synchronized with the international, so there is no need to blockade the country.

In turn, because there are new technology wafer factories in China that are constantly cultivating industry talents, foreign wafer factories have also begun to invest in China. Intel has built a wafer factory in Dagang to produce 1.2 micron 6-inch chip products, which are mainly used for export, and the rest are sold to China in short supply.

Since Intel ate the first bite of crab, the international blockade of China's semiconductor technology has basically given up treatment.

UMC in Xiamen, Deyi in Chengdu, Siemens Semiconductor and STFA are negotiating, and Motorola has moved most of its instrument semiconductor production lines to Nanjing.

As for the semiconductor projects that domestic companies are preparing to make, there are countless of them. After all, the x86 chip can't be made, can't you still make the 68000 chip? can't you make a real personal computer, can't you still build the little overlord and have endless fun?

Domestic wafer factories are showing an explosive trend, and there are not many Haier, so letting Haier get involved is also conducive to supporting Zhang Ruimin to make great efforts to promote the application of IGBT.

Sure enough, hearing that Hu Wenhai was willing to let Haier join, Zhang Ruimin's enthusiasm increased significantly.

"If the production of IGBT can be placed in Qingdao, it will be more beneficial for Haier to purchase and support IGBT chips. As long as Mr. Hu is in need, I will provide full support in the cooperation. ”

IGBT technology will certainly be firmly in the hands of Xinke, but this will not affect the licensed production. The newly established fab can absorb capital from all parties, and Xinke does not necessarily have to pursue a controlling stake.

The market for IGBTs is too large, and licensed production can also effectively reduce the resistance. In the tens of billions of dollars market, Xinke itself does not have such a good appetite. It is conceivable that this wafer fab will not only have shares in Xinke and Haier, and maybe even foreign-funded enterprises will also get involved.

Zhang Ruimin reciprocated the favor and will inevitably support Xinke on the board of directors of the fab.

Of course, having said that, if the method of authorized production is adopted, there will not be anyone who will not be able to challenge the rights and interests of Xinke.

Hu Wenhai was not in a hurry, nodded steadily and said: "Let's eat the duck first, and then consider the IGBT market." I think many people are waiting to see how big this cake will be and how much impact it can have on the industry. Only when we fight this battle well, can we make a larger market accept IGBT technology. ”

Mr. Hu is assured that Whirlpool, after receiving our commitment to supply core components such as compressors and inverters in sufficient quantities, has already started to provide peripheral technology in their hands to help Haier make up for the shortcomings in product design and production. ”

Yes, at least in the field of refrigerators, it is finally China's turn to master the core technology. Whirlpool took out its own product design advantages, and Haier took out its own core technology advantages, and the two sides reached an agreement to jointly launch a series of refrigerator products.

This agreement will ensure that both parties work together to promote fluorine-free inverter refrigerators, and the production of series refrigerators is jointly authorized by both parties. Needless to say, as long as the design of this series of refrigerators is put into production, it will be the moment when the two white power alliances declare war on European and Japanese white power enterprises.

Zhang Ruimin is obviously full of confidence in this: "Haier's corporate bonds are in short supply during this time, and the city has coordinated with the four major banks to expand the loan amount to Haier, and then we will start to acquire domestic refrigerator manufacturers." ”

"Haier's goal is to integrate the country's white electricity production capacity, go out of China, and compete with Europe, the United States and Japan for international dominance!"

"Uh, slow down, don't rush. Hu Wenhai laughed dryly: "It's better for Haier to wait for the creation of China before making efforts." ”
