Large Heat Transfer Coefficient Finned Tube Heat Exchanger
Calculation method of heat transfer area of finned tube
Jan 10, 2021 · The heat transfer principle of the finned tube is a heat exchanger composed of ordinary round tubes (light tubes). In many cases, the heat transfer coefficient of the fluid outside the tube and the fluid inside the tube to the tube wall is different.
Evaluation of Fin Efficiency and Heat Transfer Coefficient
2539, Page 3 International Refrigeration and Air Conditioning Conference at Purdue, July 16-19, 2012 Table 1 :Dimensions and test conditions of the heat exchangers in the present work. Parameter Value Fin Length, L 5.0 mm Fin Width, W 5.0 mm Fin Thickness, t 0.03, 0.05, 0.085, 0.1(1) mm Space between Fins, s 1.0 mm Thermal conductivity of fin, k 40, 80, 160, 200(1) W/m·K Testing the Heat Transfer Efficiency of a Finned-tube A higher Reynold's number indicates a more turbulent flow, greater fluid mixing and increased heat transfer. Now that you understand how to calculate the heat transfer coefficients and Reynold's numbers, let's evaluate the heat transfer efficiency of a finned tube heat exchanger by varying the flow rates of water and monoetilenglicol.
Local Heat Transfer For Finned-Tube Heat Exchangers
Air-cooled condensers used in binary-cycle geothermal power plants require the use of finned tubes in order to increase heat transfer surface area on the air side. Air is forced through several rows of these finned tubes by large fans. The condenser units can be very large, representing a large fraction of the overall capital cost of these plants.

¡°The laser cutting process uses the energy released when the laser beam irradiates the surface of the steel plate to melt and evaporate the stainless steel.¡±
Grinding Process
¡°Grinding uses abrasive particles coated or press-embedded on the grinding tool to finish the machined surface (such as cutting) through the relative movement of the grinding tool and the workpiece under a certain pressure.¡±
Slitting Processing
¡°Slitting processing is an equipment consisting of uncoiling (unwinding), leading positioning, slitting and slitting, and coiling (rewinding).¡±
