Description

Technical Field

[0002] An aluminum tube is a type of non-ferrous metal tube, referring to a metal tubular material with a hollow interior along its entire longitudinal length, which is made of pure aluminum or aluminum alloy through extrusion processing. It is a high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in the annealed, freshly quenched, and hot states, good spot welding weldability, and a tendency to form intergranular cracks when gas welding and argon arc welding are used for aluminum tubes; the aluminum tube has good machinability after quenching and cold work hardening, but poor machinability in the annealed state. Its corrosion resistance is not high, and anodic oxidation treatment, painting method, or surface aluminum cladding is often used to improve its corrosion resistance. It can also be used as a die material. The advantages of aluminum tubes are as follows: First, the welding technology advantage: The welding technology for thin-walled copper-aluminum tubes suitable for industrial production is known as a world-class problem and is the key technology for replacing copper with aluminum in air conditioner connecting tubes. Second, the service life advantage: Looking at the inner wall of the aluminum tube, since the refrigerant does not contain moisture, corrosion will not occur on the inner wall of the copper-aluminum connecting tube. Third, the energy-saving advantage: For the connecting pipeline between the indoor unit and the outdoor unit of an air conditioner, the lower the heat transfer efficiency, the more energy-saving, or in other words, the better the heat insulation effect, the more power-saving.
