Problems solved by technology

[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
3. In the brazing process, all products are vacuum brazed, and the workpiece is in a vacuum, mainly relying on heat radiation, so the production efficiency is low

Embodiment Construction

[0015] Material preparation: Select qualified raw materials according to the requirements of the drawings.

[0016] Cutting: According to the drawings, cut the qualified materials, cut the partitions, cover plates, and side plates with a shearing machine, and cut the seals, groove aluminum, aluminum rods, aluminum tubes, etc. with an aluminum sawing machine, and control the cutting Good dimensional tolerances for blanking.

[0017] Punching: Use a special machine to prepare the fins and deflectors for punching. The punching environment should be kept clean and tidy, and strictly prevent sand and dust.

[0018] Seriously maintain the tooling and fixtures, the precision of the special machine is kept in good condition, and the equal height error between the work table and the lower template is ≤0.05mm.

[0019] Adjust the height and clearance of the die, add lubricating oil to the moving parts, and conduct a test run to check whether the moving mechanism is flexible and normal....

Abstract

The process of producing aluminum plate-fin heat exchanger includes the steps of blanking, washing, mounting, brazing, argon arc welding and pressure test. The present invention adopts numerically controlled lathe with high machining precision for blanking; ultrasonic washing for high washing efficiency and high washing quality; continuous high purity nitrogen protected brazing for high brazing quality; and argon arc welding with welding robot for high welding quality and high production efficiency.

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...
