Secondary flow is used to enhance heat transfer on various wall surfaces.Vortex generators can be used to produce or control the intensity of secondary flow.In this talk, the characteristics of the tube bank fin heat exchangers with vortex generators punched on the fin surface are summarized.The engineering application field of such heat exchangers is the inter combustion locomotive, which are the inter coolers of the engine and the radiators used in the cooling system.In this system the weight, the heat transfer ability and the pressure drop are strictly required.Even for many years developing, the situation still poses a very bright challenge for researchers working on heat transfer enhancement field.
