With the penetration of the concept of "green and low carbon" travel, the global new energy vehicle market is rapidly opening up. According to the new energy vehicle database of the starting point Research Institute (SPIR): In 2022, the global sales volume of new energy vehicles exceeded 10 million for the first time, reaching 11.48 million, up year on year. Among them, China firmly occupies the position of the world's largest new energy vehicle market, and the development trend is more rapid. From January to August this year, the sales volume of new energy vehicles in China has reached 5.374 million, with a year-on-year increase of and a market share of (data source: China Automobile Industry Association).

In order to improve the economy and power of the whole vehicle and ensure the driving safety of the vehicle, it is very important to do a good job in the thermal management of the vehicle. Compared with the traditional fuel vehicle, the thermal management system of new energy vehicles is more complex, the demand for thermal management is greater, and the value of bicycles is 2-3 times higher than that of the traditional fuel vehicle. At present, liquid cooling is the main cooling method for new energy vehicles. Accordingly, the coolant pipeline needs to meet various requirements such as hydrolysis resistance, oil resistance, high temperature resistance, light weight, etc.

For new energy vehicles, although the traditional metallic aluminium cooling tube Road has high heat dissipation efficiency and light weight, the cost is high; The rubber hose has poor environmental adaptability and low cooling efficiency. In contrast, nylon tube has gradually become the main material of cooling tube Road due to its advantages of light weight, superior performance and simple processing technology. Among them, long carbon chain nylon not only has most general properties of ordinary nylon, but also has low water absorption, high dimensional stability, high temperature resistance, corrosion resistance, toughness, easy processability, etc, it is more suitable for cooling tube-way applications of new energy vehicles.

However, the temperature, pressure and assembly of different parts such as the electric cabin, chassis and battery pack are different. How to choose the nylon material and structure type corresponding to the temperature resistance grade?

The answer is all in EMS's cutting-edge solutions!
