AI Technical Summary

Problems solved by technology

As parallel-flow automotive air-conditioning radiators adopt environmentally friendly R134a refrigerant, the demand for high-precision aluminum alloy porous flat pipes for automotive air-conditioning radiators will increase greatly. However, these products have high technical content and are extremely difficult to produce. It has not yet been able to carry out large-scale production, and the products basically rely on imports from Japan

Embodiment

[0026] Example: According to the alloy composition ingredients, the aluminum alloy composition is (wt%): Sc: 0.08, As: 0.007, Si: 0.38, Fe: 0.46, Mn: 0.65, Ti: 0.09, the balance of aluminum and inevitable impurities , and then carry out aluminum alloy casting. In order to eliminate gas and non-metallic impurities, the alloy is refined. After refining, the alloy is injected into the casting mold, and the continuous casting method is carried out. The casting speed is 3 meters per hour.

Abstract

The present invention relates to an aluminum alloy and a preparation method thereof, wherein components of the aluminum alloy comprise: 0.05-0.09 wt% of Sc, 0.006-0.01 wt% of As, 0.35-0.4 wt% of Si, 0.45-0.5 wt% of Fe, 0.65-0.7 wt% of Mn, 0.09-0.1 wt% of Ti, and the balance of aluminum and inevitable impurities.

Description

technical field [0001] The present invention relates to an aluminum alloy, and more particularly, the present invention also relates to a flat tube made of the aluminum alloy, and an aluminum microchannel heat exchanger including the flat tube. Background technique [0002] Aluminum is the second largest metal material after steel in output. It is known as "universal metal" due to its good performance, wide application, large demand and low recovery cost. Statistics show that 113 of the 124 industries in my country use aluminum products, and the industry correlation is as high as 91%. Therefore, the aluminum industry is one of the important pillar raw material industries for the sustainable development of the national economy. Aluminum micro-channel heat exchanger tube is a new type of environmentally friendly refrigerant-carrying pipe component (material) used in air conditioning systems. It was first used in automotive air conditioning systems (the EU regulation was 1996, ...
