Problems solved by technology

However, when the existing aluminum alloys are finally processed into thin-walled pipes, because the ductility of aluminum alloys is lower than that of copper, cracks or leakage are prone to occur, and the corrosion resistance of existing aluminum alloy materials is not satisfactory.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile air-conditioning pipe assembly. Background technique [0002] At present, most of the materials used for automotive air-conditioning pipes are copper alloys or steels. Due to the poor corrosion resistance of steels, the heat exchange effect is not ideal, and the processing procedures are complicated and the cost is high. However, the use of copper alloys will cost too much as the price of copper rises. High, resulting in higher prices for air conditioners. The performance parameters of aluminum, steel and copper are compared in the following table: [0003] copper steel aluminum Melting point (°C) 1083 1538 660.37 Density (g / cm 3 ) 8.9 7.8 2.72 Tensile strength (MPa) 35-250 180-280 80-247 Elongation 50 40-50 50 Thermal conductivity (W / m*K) 401 46 237 Specific heat capacity (J / kg...
