Problems solved by technology

The cost of aluminum alloy castings is low, but the thermal conductivity of generally cast aluminum alloy structural parts is not high, usually around 90 W / m·K, so that the thermal conductivity is poor. Currently, pure aluminum (purity > 99% or more) is commonly used ), although the thermal conductivity is high (> 220 W / m K), its fluidity and castability are not good, and it is too soft, difficult to process, and easy to deform

An aluminum alloy prepared in the invention has a high heat conductivity coefficient of 215 to 245 W / m.K, good heat dissipation performance, high strength, good corrosion resistance, good extensibility and good processability and is applicable to the radiator of an air conditioner.

Description

Technical field [0001] The invention belongs to an aluminum alloy, in particular to an aluminum alloy material for an air conditioner radiator. Background technique [0002] Most air-conditioning heat dissipation structural parts are made of aluminum alloy, including castings, extrusions, stampings, and forgings. The cost of aluminum alloy castings is relatively low, but the thermal conductivity of generally cast aluminum alloy structural parts is not high, usually around 90 W / m·K, so that the thermal conductivity is poor. At present, pure aluminum (purity> 99% or more) ), although the thermal conductivity is high (> 220 W / m·K), its fluidity and castability are not good, and it is too soft, difficult to process, and easy to deform. At present, the study of aluminum alloys for casting with high thermal conductivity and high strength is very important for air conditioning radiators. Summary of the invention [0003] The purpose of the present invention is to provide a high t...
