• F28F 13/02 by influencing fluid boundary
• F28F 13/04 by preventing the formation of continuous films of condensate on heat-exchange surfaces, e.g. by promoting droplet formation
• F28F 13/06 by affecting the pattern of flow of the heat-exchange media
• F28F 13/14 by endowing the walls of conduits with zones of different degrees of conduction of heat
• F28F 13/16 by applying an electrostatic field to the body of the heat-exchange medium
• F28F 13/18 by applying coatings, e.g. radiation-absorbing, radiation-reflecting; by surface treatment, e.g. polishing
