Description

technical field

[0001] The invention relates to a manufacturing method of an aluminum plate-fin heat exchanger. Background technique

[0002] Aluminum plate-fin heat exchanger has the advantages of high heat exchange efficiency, small size, light weight and strong applicability, and has been widely used in industrial and agricultural production departments, mainly used in air compressors, engineering machinery, auto parts, air separation , refrigeration dryers and railway locomotives and other industries.

[0003] The original aluminum plate-fin heat exchanger has the following defects in the processing process: 1. In the metalworking process, some parts that require high processing accuracy are only processed by ordinary lathes, and the processing accuracy needs to be further improved. 2. In the cleaning process, chemical cleaning is used, namely alkali cleaning and pickling. 3. In the brazing process, all products are vacuum brazed, and the workpiece is in a vacuum, main...
