Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy processing, and in particular to a cooling device used in aluminum alloy heat treatment. Background Art

[0002] Aluminum alloy is one of the common alloys in our lives. It is an alloy with aluminum as the base and a certain amount of other alloying elements added. It is one of the light metal materials. There are many molding processes for aluminum alloys, among which casting is one of them. Casting aluminum alloy is an aluminum alloy that fills the mold with molten metal to obtain various shapes of parts. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and little restriction on part structure design. After the aluminum alloy parts are cast, their temperature is often high. In order to improve production efficiency, a cooling device is needed to cool them.

[0003] In the prior art, the existing cooling method is often to directly immerse the aluminum alloy casting into a cooling device and cool it with a coolant. The cooling efficiency of this method is slow, and after the cooling is completed, the casting needs to be manually salvaged from the coolant. When the high-temperature casting is immersed in the low-temperature coolant, more bubbles will be generated, resulting in inconvenience in salvaging and affecting the processing efficiency. At the same time, the surface of the aluminum alloy that has been water-cooled is stained with cooling water, which affects the subsequent processing of the aluminum alloy casting.
