Method and device for manufacturing hydrophilic copper pipe

Abstract

The invention relates to a method for manufacturing a hydrophilic copper pipe, which comprises the steps of continuously conveying, straightening, coating an anticorrosive material, drying, cooling, coating a hydrophilic material, drying, cooling and completing manufacturing. A device for manufacturing the hydrophilic copper pipe comprises a loading disk, a receiving disk, a straightening roll, a bottom coating device and a surface coating device, wherein the straightening roll, the bottom coating device and the surface coating device are sequentially arranged between the loading disk and the receiving disk; the straightening roll is used for straightening a copper coil; the bottom coating device is used for coating the anticorrosive material on the copper coil; the surface coating device is used for coating the hydrophilic material on the copper coil; film reduction devices for controlling thicknesses of the coating materials are arranged on the bottom coating device and the surface coating device; and a drying device for drying the coating materials and a cooling device for cooling the coating materials are arranged behind the bottom coating device and the surface coating device. According to the invention, by designing an online continuous dual-drying dual-coating method, the produced hydrophilic copper pipe has a contact angle of less than 10 degrees and has excellent anticorrosion and hydrophilicity; and the method is low in investment, is easy to control the quality and is convenient to implement the industrial mass production.

Description

technical field [0001] The invention relates to parts of heat exchange or heat transfer equipment in the field of heat exchange, in particular to a method and device for manufacturing a hydrophilic copper tube. Background technique [0002] Hydrophilic copper tube is a composite material based on copper tube. It not only has the good heat dissipation of ordinary copper tubes, but also has the corrosion resistance and hydrophilicity that ordinary copper tubes do not have. It is a good Heat dissipation materials are widely used in air-conditioning radiators, especially lithium bromide air-conditioning units. [0003] Most of the tube types used in large-scale central air conditioners are single-sided wetting tubes. The spray water cannot spray the entire surface of the coil and replenish the evaporated water in time. The formation of "dry spots" is easy to scale and affect the heat transfer performance and equipment life. [0004] The preparation of hydrophilic copper...

AI Technical Summary

Problems solved by technology

[0003] Large-scale central air conditioners mostly use single-sided wetting tubes, and the spray water cannot spray the entire surface of the coil and replenish the evaporated water in time. Not only the effective area of ​​the coil is not fully applied, but also "dry spots" are formed on the surface of the tube, which is easy to scale and affects the heat transfer performance and equipment life

[0004] Hydrophilic copper tubes are currently prepared by dipping and brushing methods, but these two methods cannot achieve continuous batch industrial production, and the production efficiency is low. Production is carried out by magnetron sputtering, but this method has high input costs and is not convenient for mass production
