liquid cooling technology has appeared as early as and during World War II. In recent years, it has been frequently seen in mobile phones, computers, data centers, etc. As technology continues to mature, liquid cooling has also appeared in the field of electric two-wheelers . Luyuan , as the first electric vehicle manufacturer to apply liquid-cooled motors, has injected new vitality into the industry.
html On August 12, Luyuan held the "Liquid Cooled Super Endurance 2.0 Quality China Tour" press conference. The new generation of long-range electric vehicles, the Liquid Cooled Super Endurance 2.0 series, was officially launched. The addition of liquid cooling technology comprehensively improved the single cruising range. The ultra-high battery life of 400 miles also significantly improves the life of electric vehicles, making it easy to ride the vehicle for 10 years without exhaustion.
Unveil the mystery of liquid cooling and promote the "5G" iteration of the industry
If you look for the origin, liquid cooling can be traced back to the Maxim machine gun during World War II. It was the first industrial product to use liquid cooling technology. In daily life, consumer-grade gaming flagship phones and high-end host chassis are also supported by liquid cooling technology. In some high-end industries, liquid cooling technology is widely used, such as servers, base stations, etc. This time Luyuan brings liquid cooling technology into the electric vehicle industry, directly promoting the industry to take a big step towards the era of "durable consumer goods".
So what exactly is liquid cooling? Liquid cooling refers to a cooling method that uses liquid with a high specific heat capacity as a working fluid for heat transfer to meet the heat dissipation needs of the equipment. Liquid cooling technology refers to the technology that uses liquid instead of air as the refrigerant to exchange heat with heating components and take away heat. Just like 5G's iterative upgrade of mobile phones, liquid cooling is a "5G" iteration of wheel hub motor . Just like lubricating oil is injected into a car engine, ultra-temperature-resistant and highly thermally conductive organic insulating liquid coolant is injected into the motor cavity, which not only effectively reduces the heat generated by the current magnetic effect work, but also isolates the moisture in the cavity from the metal and electronic components. The erosion of . It can not only ensure the driving performance of the motor and keep it as new for a long time, but also has the advantages of reducing noise, low carbon, and environmental protection.
With a series of superior performance, liquid cooling technology has finally come to the field of electric two-wheelers, and its application scope has been further expanded. Luyuan is the only company in the industry that applies liquid cooling technology to electric vehicles. Its unique liquid cooling method not only effectively solves the problems of motor demagnetization, rust, energy consumption and endurance, but also leads the way with its absolute strength. The industry is developing towards a high-quality stage.
Luyuan super endurance liquid-cooled motor High-performance industry ceiling
The core of electric vehicles is the motor. Currently, the heat dissipation of motors in the industry is divided into two major schools-air cooling and liquid cooling. In the past, electric vehicles all used air-cooling designs. As the name suggests, heat is dissipated through the air blown into the motor while riding. You must know that high temperature is the natural enemy of all motors. The normal operating temperature range of motors is 30-100°C, and the temperature of non-liquid-cooled motors is 60-120°C. The low efficiency of air cooling cannot dissipate heat in a timely and effective manner, and the internal temperature of the motor will rise rapidly. Over time, the magnetism of the motor's magnetic steel sheets will gradually weaken, thus greatly affecting the power of the motor. What’s even more frightening is that with continued high-temperature operation, a pressure difference occurs due to thermal expansion and contraction inside the motor. Dust and water vapor will be sucked into the motor together with air. Rust will occur inside the motor in a high-temperature, high-humidity and dusty environment.
Compared with air cooling, liquid cooling technology is much more reliable. Luyuan's new generation of liquid-cooled super endurance 2.0 series is equipped with super black technology liquid cooling technology, which injects insulating coolant inside the motor. According to the test data of Luyuan CNAS laboratory, even in high-performance operation, the temperature is 30°C lower than that of ordinary motors, which effectively avoids phenomena such as demagnetization of the magnets in the motor or burning of the coils, and also alleviates battery damage caused by battery loss. The problem of reduced power and endurance makes the life of the motor longer. If we take the automobile gearbox as an example, air cooling is like a dry dual clutch, which relies on air flow for heat dissipation. It is inefficient and not resistant to high temperatures, and is prone to rust and failure.The wet dual clutch relies on the immersion of oil to achieve stronger performance and long-lasting and stable power output.
Not only that, the inside of the motor can also play an anti-rust role when wrapped in insulating coolant. The gas exchange system combined with the motor sealing ring not only allows the motor to absorb moisture when the internal and external gas flows, but also prevents the penetration of dust and water. The dustproof waterproof level reaches IP68. The use of Luyuan liquid-cooled motors can effectively dissipate heat, prevent dust, and waterproof, increase the motor efficiency to more than 90%, and still maintain peak power performance after many years of use. The application of
technology has completely solved the problems that have plagued the industry for many years, such as easy demagnetization of motors and weak endurance and short lifespan of electric vehicles. Luyuan liquid-cooled motors can achieve a 10-year warranty, which can be said to be the ceiling of electric vehicle warranty. Not only that, since May this year Luyuan has upgraded and refreshed its brand positioning, namely "one bike to ride for 10 years", which demonstrates Luyuan's absolute confidence in its own technology and products. Relying on its first-mover advantage in technology, Luyuan will also strongly lead the industry into the next competitive track of high-quality development.
