摘要： A copper-containing refrigerant pipe having an anticorrosive film, a heat exchanger, and a method for producing the refrigerant pipe are disclosed. The refrigerant pipe includes a pipe body including copper or a copper alloy and an anticorrosive film formed on the outer surface of the pipe body. The anticorrosive film is obtained by applying a coating agent to the outer surface of the pipe body. The coating agent contains one or more anticorrosive agents selected from the group consisting of (A) an organic sulfonate compound, (B) a polyhydric alcohol-organic acid ester compound, and (C) an aliphatic amine compound having 8 to 24 carbon atoms. When the coating agent includes an anticorrosive agent of (C) the aliphatic amine compound having 8 to 24 carbon atoms, (C) the aliphatic amine compound having 8 to 24 carbon atoms is included in an amount of 2.0 wt % or more and 10.0 wt % or less in the coating agent.

摘要： A heat and mass transfer component comprises a lubricant-impregnated surface including hydrophobic surface features, which comprise nanostructured surface protrusions having a hydrophobic species attached thereto. The hydrophobic surface features are impregnated with a fluorinated lubricant having a viscosity in a range from about 400 mPa·s to about 6000 mPa·s. A method of fabricating a lubricant-impregnated surface on a heat and mass transfer component comprises: cleaning a thermally conductive substrate to form a cleaned substrate; exposing the cleaned substrate to a hot water or hot alkaline solution to form a thermally conductive substrate having nanostructured surface protrusions; depositing a hydrophobic species on the nanostructured surface protrusions to form hydrophobic surface features; and coating the hydrophobic surface features with a fluorinated lubricant having a viscosity in a range from 400 mPa·s to 6000 mPa·s. The heat and mass transfer component may exhibit a substantial increase in heat transfer coefficient during hydrocarbon condensation.

摘要： A heat exchanger includes a metal base defining a heat exchange channel for flowing at least one of a refrigerant and a coolant therein, and a coating layer coated at least a part of an outer surface of the metal base. The coating layer includes sol particles and an antibacterial material, where the sol particles include silica. The antibacterial material includes a rare earth element oxide. By combining the antibacterial agent containing the rare earth element oxide with sol, the advantages of each component can be fully utilized. On the one hand, it is easier to attach the antibacterial material via the sol, and on the other hand a surface of the metal base of the heat exchanger can have a good antibacterial and mold-inhibiting effects, which is beneficial to cost reduction.
