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...

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...
