WebIn the study of heat transfer, finsare surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiationof an object determines the amount of heat it transfers. WebLow-fin tubing is made in a variety of alloys and configurations. The number of fins per inch of tube length ranges from 11 to 43; fin height varies from about 0.02 to 0.125 in., and fin thickness ranges from 0.01 in. to about 0.015 in.
