Hanfeng Electric: Let the brakes of large cars be smarter

Most private cars can find traces of relays by simply lifting the hood. Automotive lights, wipers, air conditioners, power seats, power windows and doors, anti-lock devices, suspension controls, stereos, etc. all require relays. Automotive control relays have high technical requirements, and large-scale automotive high-power electronic relays are technically more demanding.

Because it is technically difficult to overcome, electronic relays for automatic control of vehicle retarders used in large-scale automobiles have always been a gap in the market. A college entrepreneurship team solved this technical problem in four years.

Product Innovation

In 2011, Hangzhou Hanfeng Electric Co., Ltd. was formally established. Prior to this, they had completed a full four years of research and development work. “We started our technology research and development in 2007. We didn't register our company until 2011 and we decided to launch our products in 2014.” said Zhang Bo, chairman of Hanfeng Electric Co., Ltd., who developed the intelligent vehicle-mounted electronic relay. Has successfully applied for a number of national patents, including invention patents.

Zhang Bo told reporters that because of its large weight and load, large-scale automobiles are more difficult to brake and brake. The retarder used to control it has very high requirements for relays. Currently, large-scale automobiles use mainly mechanical relays. However, the traditional mechanical relay has a single function, and there are also many drawbacks, such as waterproof, anti-corrosion, shock and other safety protection issues. Hanfeng Electric not only successfully solved these problems, but also achieved substantial savings in resources. This high-power electronic relay not only can automatically control the retarder of large-scale automobiles, but also can be applied to all electric appliances such as ships and aviation that use DC power. The successful development of this product has filled the gaps at home and abroad.

At the same time, this product of Hanfeng Electric also adds functions such as time control function, discriminating function, storage function, monitoring function, frequency conversion amplitude modulation, etc., which can be automated according to requirements and stipulated contents, and has strong anti-interference, thus greatly improving The actual utility of the relay.

Another piece of business that Zhang Bo's team is doing is an inductive electronic wall switch. As its name implies, it is the lighting switch that controls the lighting in the room. However, the difference is that this product has changed the method of manual switching in the past and converted it into a touch type, achieving the effect of quiet indoor and neat switches.

market expectation

Han Feng Electric's relay products and services are mainly targeted at large domestic and foreign well-known manufacturers, such as the world's top brand French Taylor music company, domestic Yutong buses. This car-mounted electronic relay was not successfully developed until recently and passed the lab and road tests. Not long ago, an agreement was reached with a bus company in Shanghai to install a small batch of pre-commissioning on 10 buses. Zhang Bo said that the safety issues of such large-scale automobiles are particularly important. Therefore, the requirements are also very strict. According to industry practice, it is necessary to undergo a rigorous trial to start mass production.

"We have confidence in the future product market, not only because the current domestic product is in a blank market stage, but more importantly, we have prioritized technological breakthroughs in many world-renowned manufacturers." Zhang Bo said that as the world's third The American company Petri, which is a major commercial vehicle manufacturer, invested US$20 million in the research and development of this project and has not succeeded so far. "We can responsibly say that our company has already taken the lead in the world in this field."

Q: What are the advantages of the company team?

A: Our team recently introduced a national "Thousand Talent Plan" talent. The international senior expert came back from France, worked in this field for many years and achieved fruitful results. In addition, the R&D team has also introduced many senior professionals in related fields.

Q: How is the profitability of the company?

A: Our company has been in the research and development stage since its establishment in 2011. It has only recently started to put into trial operation and there is no sales revenue. Therefore, the capital investment mainly depends on the sales revenue of the traditional traditional relays.

Q: What is the bottleneck faced by the company?

A: We have encountered some difficulties in the development and production of inductive electronic wall switches. We have received a small amount of orders before. However, because we belong to the college students, our R&D personnel and funds are not well-placed, so we can't be very confident in this one. Next, the company's main direction of attack is still on the electronic relay, and the inductive electronic wall switch may be put on hold for some time.

Spin Flash Dryer

Hot air enters the stirring part of drying chamber from the bottom, material is stirred by stirring device and then the hot air exerts strong shearing, blowing, floating and rotating effect to material. Therefore material is crushed by centrifugal, shearing, impacting and friction effect. It strengthens the heat exchanging process. In the bottom of drying chamber, big and damp granules are crushed by stirring device, the particles with low moisture content and small size are lifted by rotary air stream, and be further dried. Gas and solid two phases rotary flow, inertia of solid phase is bigger than gas phase, the relative velocity between gas phase and solid phase is high, heat exchanging efficiency is strengthened, so the drying intensity of this machine is high.
