The invention provides a cooling treatment method for an aluminum alloy plate, and belongs to the technical field of cooling technologies. A cooling treatment method for an aluminum alloy plate is characterized by comprising the following steps that S1, a part is cleaned and deoiled before heat treatment; s2, after the part is subjected to solid solution heating to 489.4-493.4 DEG C, the quenching transfer time is 4.7 s, the part is transferred into a quenching medium and stays for 3 min, the temperature of the quenching medium is controlled to be 21.2 DEG C before quenching, the quenching medium is a polyethylene glycol solution with the concentration being 18%, and an immersion type cooling mode is adopted; and S3, the part is taken out and naturally aged for 4 days, and the room temperature is controlled to be 25 DEG C. The quenching method has the advantage of enabling the 2024 aluminum alloy to achieve the most appropriate quenching effect. 本发明提供了一种铝合金板的冷却处理方法，属于冷却技术技术领域。一种铝合金板的冷却处理方法，其特征在于，包括以下步骤：S1、在热处
