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

Embodiment Construction

[0009] The heat sink aluminum alloy with good processability, the weight percentage of its constituent elements is: silicon 5.5-6.0, magnesium 1.2-1.5, copper 0.3-0.4, iron 0.4-0.6, chromium 2.3-2.4, Nb1-1.2, V3. 5-3.6, Zr0.6-0.9, Be0.1-0.3, La0.06-0.08, Ho0.16-0.19, Li0.1-0.15, Ba0.06-0.08, and the balance is aluminum.

[0010] The manufacturing method of radiator aluminum alloy with good processability includes smelting, slag removal, detection and adjustment of alloy composition, adding refining agent for refining, casting, cooling down to 110-135°C at a rate of 80-95°C / hour after casting, and holding for 40 -60 hours; then, heat up to 520-545°C at a rate of 135-155°C / hour, and keep warm for 4-5 hours; then cool down to 360-380°C at a rate of 70-90°C / hour, and keep warm for 2-3 hours; Then cool down to 160-180°C at a rate of 40-50°C / hour, keep warm for 2-3 hours; then put it in ice water at 0°C for 3-4 hours;

[0011] The refining agent is formed by mixing and briquetting ...

Description

technical field [0001] The invention belongs to an aluminum alloy, in particular to an aluminum alloy material for an air-conditioning radiator. Background technique [0002] Most of the heat dissipation structural parts of air conditioners are made of aluminum alloy, including castings, extruded parts, stamping parts and forging parts. 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. At present, the study of casting aluminum alloys with high thermal conductivity, high strength and good processability is very important for air-conditioning radiators.
