Abstract: In order to achieve "bath-type cooling and carpet-type heating", air conditioners need to use large-motion air deflectors, while traditional air deflectors use injection molded parts, which are low in strength and easy to deform, and are difficult to meet the requirements of large-movement air deflectors. As a representative of lightweight materials, aluminum alloys can meet the requirements of lightness and toughness for large-motion air deflectors. It is the preferred material to replace injection molded parts in mid-to-high air conditioners. Cold stamping of aluminum alloy profile is prone to wrinkling, embossing, and collapsing. Combined with the structural characteristics and production requirements of the air deflector, using the milling and distributed forming methods, the processing technology of the aluminum alloy profiled was developed, the processing of the profiled aluminum alloy air deflector was realized, and the level of the air conditioner was improved to meet the demand of consumption upgrade in the new era.
