Stainless Steel Aluminum Fin Heat Exchanger for Automobile Production Line Application

Stainless Steel Aluminum Fin Heat Exchanger for Automobile Production Line Application

Structure and Principle

Core Components: It is mainly composed of base tubes, fins, and a frame. The base tubes are usually made of stainless steel, such as 304, 316L, etc., which are responsible for the circulation of the medium and heat transfer. The fins are made of aluminum and are attached to the surface of the base tubes. The shell provides support and protection for the entire heat exchanger.

Heat Transfer Principle: The heat transfer medium flows through the stainless - steel base tubes, and the aluminum fins increase the heat transfer area. Air or other cooling media flow over the fins, and through the combined action of conduction and convection, heat is transferred from the medium in the tubes to the outside, achieving the purpose of heat exchange.

Advantages in Automobile Applications

High Heat Exchange Efficiency: The aluminum fins greatly increase the heat transfer area. For example, louvred- shaped fins have a low wind resistance and can promote turbulent flow of the air, increasing the heat transfer coefficient by 3 - 5 times compared with laminar flow. The tight combination of the base tube and the fins through high - frequency welding or brazing reduces the contact thermal resistance, enabling rapid heat transfer.

Good Corrosion Resistance: The stainless - steel base tube has good corrosion resistance, which can prevent the heat exchanger from being corroded by the cooling medium or the external environment in the automobile, especially in harsh environments such as high humidity and salt spray. This helps to extend the service life of the heat exchanger.

Low Energy Consumption: The smooth inner wall of the stainless - steel base tube reduces the flow resistance of the medium, and the low - wind - resistance fins reduce the energy consumption of the fan. For example, the use of low - wind - resistance fins can reduce the fan energy consumption by 20%, which is beneficial to improving the energy efficiency of the automobile.

Compact Structure: It has a compact structure and a small volume, which can save installation space in the automobile, especially suitable for the limited space layout of modern automobiles.

Application Scenarios in Automobile Production Lines

Engine Cooling System: It is used to cool the engine coolant to ensure that the engine operates within a suitable temperature range, preventing overheating and improving the reliability and performance of the engine.

Air - conditioning System: In the automobile air - conditioning system, it is used as an evaporator or condenser to transfer heat between the refrigerant and the air, realizing the functions of cooling, heating, and dehumidifying the air in the car, and improving the comfort of the vehicle interior.

Battery Thermal Management System: For new energy vehicles, it is used to cool or heat the battery pack to maintain the optimal operating temperature of the battery, improve battery life and performance, and ensure the safety and stability of the battery system.
