Manufacturing process of novel tube-sheet evaporator

Abstract

The invention discloses a manufacturing process of a novel tube-sheet evaporator. The manufacturing process comprises the steps that an aluminum tube coil material is straightened and cut into a straight material of a specific length; the straight material is bent to be an S-shaped aluminum tube with fourteen bent corners; flattening forming is conducted; at the same time, it is ensured that the specific size of the tube end of the S-shaped aluminum tube is not flattened, and the height of the flattened area of the aluminum tube is controlled to be 0.6-0.68 time of the original diameter; then a copper transition tube is welded to the pipe end of the S-shaped aluminum tube; the surface of an aluminum board which is subjected to shear forming is coated with a sulfuration film; the flattened S-shaped aluminum tube and the aluminum board with the surface coated with the sulfuration film are subjected to sulfidizing; the product after sulfidizing forming is bent to be in a U shape; paint spraying, curing and drying are conducted on the U-shaped product, and the novel tube-sheet evaporator is manufactured. The tube-sheet evaporator is good in refrigerating effect, low in energy consumption, high in corrosion resistance and suitable for being used on novel energy-saving and environment-friendly refrigerators.

Description

technical field [0001] The invention relates to the field of evaporator production, in particular to a manufacturing process of a novel tube-plate evaporator. Background technique [0002] The evaporator is the key refrigeration component in the refrigerator air conditioner, and the heat dissipation performance of the evaporator directly determines the overall energy saving characteristics of the refrigerator air conditioner. In recent years, the popularization and use of environment-friendly and energy-saving refrigerator air conditioners is the trend of market development. For this reason, the inflation evaporator with large surface area and good cooling effect is widely used in refrigerators.

AI Technical Summary

Problems solved by technology

Screening and pressurized air blowing must be carried out during the production and processing of blown evaporators. During this process, the direction of high-pressure airflow cannot be completely controlled, resulting in a large number of branch gaps inside the blown evaporator, which makes the blown evaporator installed The resistance of the after-refrigerant to run in it is large, and the return speed is slow

In addition, the colorless and transparent storage box in the refrigerator is often worn and broken during continuous loading and unloading, and it will also scratch the inner liner of the refrigerator.
