The condenser is a piece of equipment used to effectively transfer heat from water to the environment. The fin and tube condenser is the most commonly used in commercial applications. The improved performance of heat transfer in the fin and tube condenser is a significant area of study all over the world because optimizing the efficiency of heat transfer in the condenser will contribute to enhancing the effectiveness of system performance. The vapor deposition, plasma spray, and thermal spray techniques are being used, and it is determined that a heat transfer enhancing coating improves condenser performance. This review discusses the nanomaterial coating over the fin and tube condenser in detail. The various nanomaterial coatings with various propositions and coating methods had been discussed with the evidence of previous researchers. At a 50‐degree inclination angle on the condensate plate, the condensate over the coating surface increases by more than 30%. The thermal properties of the working fluid are improved over the condenser, and the overall effectiveness of the condenser is increased by approximately 40% over the non‐coated condenser. A 1% volumetric concentration of Nanoparticles in the coated material achieves a maximum efficiency increase of 78.7%.

“…In recent years, nano-SiO 2 was often used to build superhydrophobic coatings. [39][40][41] Our team [42] prepared an abrasion-resistant superhydrophobic coating on the basis of hydrophobic nanosilica, which reduced the ice adhesion strength (IAS) by 91.8%. Carbon nanotubes (CNTs) have good toughness and distinctive one-dimensional structure, making it easy to…”

Linearly structured carbon nanotubes are intertwined to form complex micro and nanoscale structural undulations, and the structural undulations of the coating are further enhanced using large‐size nano‐SiO2. It can be prepared the composite superhydrophobic coating (S‐C coating) with contact angle of 165.3° and sliding angle of 1°. Small‐size nano‐SiO2 can doped into the 3D‐network structure formed by the carbon nanotubes and act as anchor points to fix the structure. This enhances the stability of the coating as well as the abrasion resistance. The coating exhibits the good long‐term durability and the ability to face harsh service environments. Due to the presence of the air layer with low heat transfer rate on the coating surface, the S‐C coating demonstrates good anti‐icing properties compared to the uncoated tinplate. By the lower surface free energy and contact area with the ice layer of the coating, the coating also exhibits good deicing performance. The ice adhesion strength (IAS) of the coating is only 11.5 kPa, which is a decrease of 97.3% compared with that of the uncoated tinplate. The photothermal properties of carbon nanotubes and the ability of the micro‐nano structure to reflect light enable the coating to exhibit excellent photothermal properties. This also accelerate the melting and shedding of the ice layer on the coating.This article is protected by copyright. All rights reserved.
