Abstract
A high efficiency modular OLF heat exchanger with heat transfer enhancement is disclosed. The OLF heat exchanger has an oblique louver fin provided with oblique strips. The oblique louver fin thus effectively forms transverse and longitudinal vortexes in a main gas flow while breaking the boundary layer of the gas flow, thus having an improved heat transferring effect. In the OLF heat exchanger, a plurality of flat tubes are assembled with two opposite header pipes, thus forming a module. The OLF heat exchanger is thus manufactured while easily permitting changes in its size and heat exchanging capacity by assembling a selected number of modules into a single body using a plurality of header pipe sockets. The oblique strips violently mix the gas flow and thereby further improve the heat transferring effect of the louver fin. The oblique louver fin thus has advantages expected from typical louver fins with swirlers and typical offset strip fins with swirlers.
