The invention relates to a micro-channel aluminum flat tube continuous extrusion process for automobile air conditioner and household air conditioner refrigeration. The process is as follows: a refining agent is added to prepare a round aluminum rod coiled material with the diameter of 9.5mm, the round aluminum rod coiled material is straightened and cleaned, the surface-cleaned round aluminum rod is continuously extruded and converted into various micro-channel aluminum flat tubes of different specifications on a continuous extrusion machine through a mold, after zinc spraying, cooling is carried out through a cooling water tank, and then reeling and winding discs are carried out after eddy current flaw detection and code spraying identification. According to the process, on one hand, the process extrusion ratio is low, so that the energy consumption is lower producing products in the same specification, the service life of the continuous extrusion machine and the mold is longer, the production cost can be obviously reduced, and the production efficiency is improved; and on the other hand, the leakage rate of the micro-channel aluminum flat tube is reduced, the defects in production can be overcome, particularly, aluminum scraps formed on the surface of the micro-channel aluminum flat tube can be reduced, and the rejection rate caused by the defect of the aluminum scraps can be lower than 3%.
