HEADER PIPE MATERIAL FOR PARALLEL FLOW CONDENSER, AND PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2023/240965

A1

A header pipe material for a parallel flow condenser, and a preparation method therefor and the use thereof. In the header pipe material for a parallel flow condenser, an outer-layer alloy comprises the following components: 0.8-1.3% of silicon, 0.05-0.25% of iron, less than or equal to 0.1% of copper, less than or equal to 0.05% of manganese, less than or equal to 0.03% of magnesium, 0.85-1.15% of zinc, and less than or equal to 0.05% of titanium, with the balance being aluminum; and a core-layer alloy comprises the following components: 0.05-0.12% of silicon, 0.05-0.18% of iron, 0.05-0.2% of copper, 1.0-1.5% of manganese, less than or equal to 0.03% of magnesium, less than or equal to 0.1% of zinc, and less than or equal to 0.05% of titanium, with the balance being aluminum. By means of the specific contents of the metal components in the outer-layer alloy and the core-layer alloy, the header pipe material has greatly improved corrosion resistance, and can be used in a parallel flow condenser equipped with a SiZnFlux extrusion porous pipe.
