A few typical fin configurations are shown in Fig. 11-30a. Longitudinal fins are used in double-pipe exchangers. Transverse fins are used in cross-flow and shell-and-tube configurations.
Abstract. This discourse discusses the use of extended surface heat transfer in heat exchangers. The size and cost of an exchanger is dependent upon the heat duty, the allowable pressure drop, and the geometry of the heat transfer area. FORCED CONVECTION HEAT TRANSFER FROM Ashutosh for determining effectiveness of extended surfaces. Appl and Hung (21) utilized fins of restrict.ed l(:<·nq'th with individually optimum profiles prescribed minimuIn clearance between the fins. They gave equation~ for the nu.."Uber of fins to be used to provid~ the least lTr'~L'Jht o'F fins for a given surface heat dis::;.:i.Dation. Finned Tube Heat Exchangers - EnggCyclopediaSurface area available for heat transfer is quite an important determinant of the overall heat transfer. Finned tube exchangers are known for maximizing heat transfer surface area, by design. Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins. Finned Tube----Extended Surface Tube Heat Transfer Finned Tube----Extended Surface Tube Heat TransferIntroduction. Extended surfaces tube have fins attached to the primary surface on one side of a two-fluid or a multifluid heat exchanger.Fins can be of a variety of geometryplain, wavy or interruptedand can be attached to the inside, outside or to both sides of circular, flat or oval tubes, or parting sheets.
2) The condenser of Refrigeration System:- Counter Flow tube type heat exchanger. Because High performance due to large surface area Compact and light in weight In tubes generally, turbulent flow is developed which reduces scale deposition. Less installation and maintenance cost. 2. Suggest the type of heat exchangers for following applications Heat Exchanger Tubes - Finned Tubes - U Tubes ProfinsHeat Exchanger Tubes by Profins, since 1978. Since our inception in 1978, Profins have become one of the world's foremost manufacturers and suppliers of heat exchanger tubes.. Initially created to manufacture high-quality finned tubes for air-cooled heat exchangers, our product portfolio has evolved over the course of 35 years experience within the thermal transfer business. Heat transfer tubes with internal extended surface Jun 08, 1976 · FIGS. 3 and 4 show another type of interior extended heat exchange surface tube made in accordance with the present invention. The heat exchange tube indicated generally as 22 has a sidewall 24 which is generally cylindrical in configuration and a seam 26 which extends longitudinally along the tube 22 and, as seen best in FIG. 4, is a butt seam.

Extended Surface - The extended surface refers to the heat transfer surface in the form of fins or studs, added to heat absorbing elements. Extension Ratio - Extension ratio is the ratio of total outside exposed surface to the outside surface of the bare tube. Flux Density, Average - Flux density, average is the heat absorbed divided by Shell and Tube Heat Exchangers, LMTD, Extended Surface Apr 30, 2015 · Extended Surface Heat Exchangers "Extended surface" is a term that covers many possibilities but the type that we shall be most concerned with is the round tube with round fins essentially transverse to the tube axis The low-finned tube commonly used in shell and tube exchangers provides about 3 to 4 times as much outside area as inside Steel Studded Tubes Extended Surface Tube For Boiler Quality Boiler Fin Tube manufacturers & exporter - buy Steel Studded Tubes Extended Surface Tube For Boiler Parts ASTM A106 152X10X7000mmL from China manufacturer. What is extended surface tubes_Finned TubeExtended surface tubes generally and regularly used for efficient cooling or heating. These extended surface tubes are used in air-cooled heat exchangers, shell and tube heat exchangers, Evaporator, condensers even used in furnaces. Extended surface tubes also called finned tube. Fins are basically external or inserted on outside of tubes in order to increase the total surface area and increase
Finned tube surface area ratio between bare tube and extended surface information is always provided by the finned tube manufacturer. RE:heat transfer area of a finned tube EdStainless (Materials) 30 Oct 15 02:53. You have the guys that designed the fining. EXTENDED SURFACE HEAT TRANSFER - ThermopediaTwo major types of tube-fin extended surfaces are:a) individually-finned tubes, and b) flat fins (also sometimes referred to as plate fins) with or without enhancements extended surface tubes interruptions on an array of tubes as shown in Figure 2. An extensive coverage of published literature on and correlations for these extended surfaces are provided by Webb (1994), Kays and London (1984) and Rozenman (1976).
