Design and preparation method of air cooler steel-based aluminum finned tube bundle anti-scaling nano composite coating

A nano-composite, aluminum fin technology, applied in design optimization/simulation, coating, liquid chemical plating, etc., can solve the problem that the heat dissipation efficiency of finned tubes is greatly affected, the fins are easy to absorb dust particles, and reduce air-condensed vapor. To solve problems such as device efficiency, achieve excellent anti-fouling performance, reduce corrosion and aging rate, and save labor and material costs.

Problems solved by technology

The ambient humidity is low, the dust is large, and the fins are easy to absorb dust particles, resulting in an increase in thermal resistance and a decrease in heat transfer coefficient, thereby reducing the efficiency of the air-cooled condenser
During the condensation process of the air cooler, due to the high concentration of dust in the air, the air medium in the channel of the finned tube carries dust particles, which are easily adsorbed inside the aluminum finned tube, causing channel blockage
Dust has a great impact on the heat dissipation efficiency of finned tubes, and it needs to be washed with high-pressure water, which is a great waste of water resources
[0003] In the prior art research on anti-scaling and anti-ashing of air coolers, the research on coating anti-scaling and surface modification is somewhat lacking, and due to the special structure of finned tubes, it is difficult to obtain the performance of steel-based aluminum finned tube bundles of air coolers. Excellent nanocomposite coating, so far, there is no literature report or practical application of Ni-P composite coating applied to air cooler finned tube bundles, and research on its inhibitory effect on fouling

Description

technical field [0001] The invention relates to a steel-based aluminum finned tube bundle of an air cooler, in particular to a design and preparation method for an anti-scaling nano-composite coating of the steel-based aluminum finned tube bundle of an air cooler. Background technique [0002] Air-cooled condensers are mostly used in dry and water-scarce areas. The ambient humidity is low, the dust is large, and the fins are easy to absorb dust particles, resulting in an increase in thermal resistance and a decrease in heat transfer coefficient, thereby reducing the efficiency of the air-cooled condenser. During the condensation process of the air cooler, due to the high concentration of dust in the air, the air medium in the channel of the finned tube carries dust particles, which are easily adsorbed inside the aluminum finned tube, causing channel blockage. Dust has a great impact on the heat dissipation efficiency of finned tubes, and it needs to be washed away with high...
