Description

TECHNICAL FIELD

[0001] The application belongs to the field of automobiles, and particularly relates to a composite material for a charge air cooler pipe and a preparation method. BACKGROUND

[0002] Many components of an automobile need to work within a specified temperature range, and too high or too low temperature will affect the performance of the vehicle, and even cause failure. For example, the battery pack of an automobile often generates heat during work or is too low in temperature in winter, and exceeds the specified temperature range, and a special heat exchange circuit usually needs to be designed.

[0003] For a supercharged engine, a charge air cooler is an important component of a supercharging system. Whether it is a mechanically supercharged engine or a turbocharged engine, a charge air cooler needs to be installed between a supercharger and an engine intake manifold. Since the heat exchanger is located between the engine and the supercharger, it is also called an intermediate cooler, and is simply referred to as a charge air cooler.

[0004] Since the temperature of exhaust gas discharged by the engine is very high, heat conduction through the supercharger will increase the temperature of intake air. Moreover, the density of air will increase in the process of being compressed, which will inevitably also cause the temperature of air to rise, thereby affecting the charging efficiency of the engine. If the charging efficiency is to be further improved, the temperature of intake air needs to be reduced. Data shows that, under the same air-fuel ratio condition, the power of the engine can be increased by 3%-5% if the temperature of supercharged air is reduced by 10℃.

[0005] With the development of society, people have higher and higher requirements for engines. In order to meet the use requirements of people, the requirements for charge air coolers are increasing, and the requirements for charge air cooler pipes are also increasing.

[0006] With the improvement of engines, the performance of engines is getting higher and higher, and the requirements for charge air coolers are also increasing. The tensile strength and corrosion resistance of existing charge air cooler pipes cannot meet the requirements, so that the service life of the charge air cooler is not long.

[0007] Moreover, the existing composite material for a charge air cooler pipe is directly smelted during processing, and the gas and impurities in the interior thereof cannot be quickly discharged during smelting, so that the smelting time is relatively long, the smelting efficiency is not high, and a large amount of impurities will be left in the interior after smelting. Therefore, the product control of the produced composite material for a charge air cooler pipe is poor, and cannot meet the use requirements of people. For this reason, a composite material for a charge air cooler pipe and a preparation method are invented. SUMMARY
