Microchannel flat tubes have the following applications in the automotive industry:
1. Automotive air conditioning system:
Efficient heat exchange: During the operation of automotive air conditioning, heat exchange is required to achieve cooling or heating. The internal structure of microchannel flat tubes is special, with a smaller hydraulic diameter and a thin boundary layer, making the flow of fluid inside the tube closer to laminar flow and heat transfer more rapid and efficient. Compared to traditional round tube heat exchangers, microchannel flat tubes can complete heat exchange in a shorter time, greatly improving the cooling and heating effects of automotive air conditioning. For example, in hot summer, it can quickly reduce the temperature inside the car, providing a comfortable environment for drivers and passengers; In the cold winter, the temperature inside the car can also be quickly increased.
Reduce refrigerant charge: The internal channel design of microchannel flat tubes is more sophisticated, and the distribution of refrigerant inside the tube is more uniform, which can fully utilize the heat transfer performance of the refrigerant. Therefore, the refrigerant charge required for automotive air conditioning systems using microchannel flat tubes is relatively small. This not only reduces the operating costs of car air conditioning systems, but also helps to minimize the impact on the environment, as some refrigerants may pose certain hazards to the environment.
Lightweight: The lightweighting of automobiles is one of the important trends in the current development of the automotive industry, which is of great significance for improving fuel economy, reducing energy consumption, and increasing range. Microchannel flat tubes are usually made of lightweight materials such as aluminum alloys, which are relatively light in weight. Applying them to automotive air conditioning systems can effectively reduce the overall weight of the car.
2. New energy vehicle battery thermal management system:
Heat dissipation: The battery of new energy vehicles generates a large amount of heat during the charging and discharging process. If the heat cannot be dissipated in a timely manner, it will affect the performance, lifespan, and even safety of the battery. Microchannel flat tubes can serve as heat dissipation components in battery thermal management systems, carrying away the heat generated by the battery through the internal flow of coolant, and maintaining the battery operating within a suitable temperature range. Efficient heat dissipation performance helps improve the charging and discharging efficiency and safety of batteries, extending their lifespan.
Heating: In low-temperature environments, the battery performance of new energy vehicles will be greatly affected. In order to ensure the normal operation of the battery, it is necessary to heat it. Microchannel flat tubes can be used in the heating system of batteries, providing heat to the battery through circulating heat medium, increasing the temperature of the battery, and enabling it to work normally even in low temperature environments.
3. Engine cooling system:
Coolant transmission: The engine generates a large amount of heat during operation, which needs to be dissipated through the cooling system. Microchannel flat tubes can serve as pipelines for transporting coolant from the radiator to the engine, absorbing the heat generated by the engine before returning to the radiator for heat dissipation. The efficient heat transfer performance of microchannel flat tubes can improve the cooling effect of the coolant and ensure that the engine operates within the normal temperature range.
Turbocharging system cooling: For turbocharged engines, the turbocharging system also generates high temperatures during operation and requires cooling. Microchannel flat tubes can be used in the cooling circuit of turbocharging systems to provide effective cooling, improve the reliability and service life of the turbocharging system.
4. Automotive exhaust aftertreatment system:
Urea solution transmission: In the exhaust aftertreatment system of diesel vehicles, urea solution is required to reduce nitrogen oxide emissions in the exhaust. The microchannel flat tube can serve as a transmission pipeline for urea solution, transporting it from the urea tank to the exhaust gas treatment device, ensuring the correct supply of urea solution and improving the efficiency of the exhaust gas post-treatment system.
Heat recovery: Automobile exhaust contains a large amount of heat, and by utilizing the heat transfer performance of microchannel flat tubes, the heat in the exhaust can be recovered. The recovered heat can be used to heat the air inside the car, preheat the engine coolant, etc., improving the energy efficiency of the car and reducing fuel consumption.
