Help to build a cooling system suitable for cars three giant cooling fans in Taiwan For those familiar with cars, the cooling fan is no longer a strange component. Compared with various automotive electronic products such as fuel consumption display, interior temperature and humidity control, GPS navigator, air purifier, LED lamp and CD / DVD player, the cooling fan of cars is particularly important, Because poor heat dissipation design will seriously endanger the reliability and durability of these electronic products. Under the exposure of high temperature weather, it may also lead to vehicle failure and affect its service life. Specifically, a large amount of heat will be generated during the driving of the car. If the car cooling fan is not used to cool it in time, the engine is likely to fail due to high temperature and even directly lead to the scrapping of the engine. Of course, the cooling fan blades do not work all the time. Taiwan's three giant motors, a professional R & D and manufacturer of cooling fans, said that only when the temperature of the car engine rises to a certain value, the temperature sensor sends an alarm, and the fan will start blowing and cooling. "Automobile cooling fan" Because most people do not have a professional and comprehensive understanding of the application of automobile cooling fans, many people will think that the cooling fans are similar and can be used. In fact, this is not the case. There are a wide range of cooling fan products on the market, but there are still some advantages and disadvantages in terms of performance and appearance. Taking Taiwan's three giant motors as an example, compared with most cooling fan manufacturers in the market, Taiwan's three giant motors pay more attention to innovative independent research and development and advocate the production of more energy-saving and environmental friendly cooling fans. Starting from the details of the product, the ball bearing in the cooling fan of three giant motors can greatly reduce the friction. The application of three giant's exclusive vortex generator and vacuum effect technology can not only effectively reduce the noise caused by the operation of the fan, but also improve the internal heat dissipation performance. It has the characteristics of long service life, high flow rate and low wind pressure, It is more helpful to build a cooling system suitable for cars.

In 1997, Yuanshan technology established the thermal technology management division and led Yuanshan technology into the field of information industry. In recent years, y.s. Tech's heat dissipation products with its professional design, such as DC brushless heat dissipation fan, DC drum fan and other special heat dissipation devices for customers. In only a few years, y.s. Tech's heat dissipation products have been deeply and famous in the world's information, communication, automobile and general industrial markets. 2、 Nippon power Nidec Nidec talent top has accepted the entrustment of Nidec to start the production of cooling fans. For 18 years, it has been relying on world-class fan motor technology and production process to provide customers with more reliable cooling guarantee（ Nidec is the world's top manufacturer and supplier of small brushless motors, with factories and branches all over the world. At the same time, its mechanical and electrical products such as special bearings are also the world's leading. As one of the core components of fan, small brushless motor has more than 30 years of experience in this field. The original Nidec fan equipped with Nidec original brushless motor is undoubtedly one of the world's top products in terms of quality 3、 Delta Delta Delta (Delta Electronics), founded in Taiwan in 1971, is the world's leading switching power supply manufacturer. It has many factories and business bases in various countries and regions around the world. It is one of the most influential Chinese enterprises in the world. Delta has nearly 20 years of experience in fan production, and its products cover almost all applications. Delta fan is the only brand fan equipped with a large number of advanced equipment and even key facilities of famous factories such as IBM, HP, Intel, Emerson and Siemens, with solid and reliable quality. 4、 Qihong AVC Taiwan Qihong, as the world's largest radiator manufacturer, has won the recognition of international manufacturers and consumers with advanced design concept, excellent manufacturing technology and strict quality control.

In recent years, the greenhouse effect has become more and more serious, leading to global warming and increasingly serious ecological environment. Research shows that climate warming is partly due to the excessive use of air conditioning, especially the opening of air conditioning in large places all year round, which leads to the increasingly serious greenhouse effect. At this time, the use of large industrial fans in large places is a better solution at present. The application of industrial fans can be said to solve the development trend of cooling in summer in tall factories, warehouses, waiting rooms, swimming pools and other places, without carbon dioxide emission, and has made a contribution to the earth. So, how should the factory choose the appropriate industrial fan? In my view, as like as two peas, the choice of industrial fans is the first thing to do is to focus on manufacturers. Good manufacturers can make double guarantees in terms of cost and safety. At present, the industrial large fan industry is not a popular industry in China, but there are many enterprises engaged in the manufacturing and processing of industrial large fans, which makes it difficult for enterprises to choose. At present, the manufacturing and processing of large industrial fans is still dominated by traditional processes, but according to Xiaobian, some industrial fan manufacturers have begun to make changes, and continue to improve the configuration of industrial fans to realize intelligent operation, which is more safe and reliable. For example, the following King industrial fan configuration is very ideal. 1. Brand of reduction motor: Nord Nord motor imported from Germany, NEMA standard IE2 new generation of energy-saving and efficient motor, no vibration, silent, efficient and maintenance free; Simrit double oil seal (output shaft) from Freudenberg, Germany; Special SKF imported VL reinforced bearing 2. Frequency conversion control: Schneider Electric suit Top inverter configuration in the industry, Schneider Electric package: ① The safety protection module automatically cuts off the output in case of accident; ② Adapt to harsh environment, effectively shield electromagnetic interference, power grid fluctuation and high temperature, and the protection grade is IP55; ③ It has passed the authoritative EMC certification, CCC certification and anti leakage test of SGS company in Switzerland; ④ UL, EMC, LVD, ROHS certification. 3. Core technology: mortise and tenon structure connection is safe and reliable. When the non rigid connection equipment is running, the blade can float up 3 °, with larger coverage area, no cavity in the center, better comfort. 5. The blade has better dynamic balance, no vibration, no resonance, more stable and silent operation, safer and more energy-saving 4. Buffer device, inner cone, anti falling ring and other connection protection 5. Core technology: variable cross-section streamlined aviation airfoil anti-collision blade has hig...
