New techniques of plate-fin heat exchangers and its application

The researches made on plate- fin heat exchangers by authors were introduced.Firstly,a surface treatm ent method for fins and parting sheet is proposed in order to enhance their resistance to corrosion and hydrophilic capability.Secondly,a rapid innovation system which involved a lot of functions such as optimal thermal design,param etric drawing and rapid quotation is developed.The practice application of this system shows the design efficiency increases8to10 tim es and the cost decrease vastly.Thirdly,several new type of plate- fin heat exchangers with special performance,such as corrosion- proof,anti- fouling and high temperature resistant etc,were developed through adopting new advanced materials and new advanced manufacturing technology. Finally,the strength analysis for plate- fin heat exchangers subjected to high pressure was carried out.Some design criteria to ensure the reliability of plate- fin heat exchangers are obtained.
