A
Cylinders of internal combustion engines, metal of good heat transfer properties, such as compnssors. and the like often require cooling cqpper, aluminum, silver, etc., may be used, copfins. The fins may be cast integrally with the 5 per being at present preferred. barrel, but since the cylinder is usually of a The molded structure may for some purposes strong metal like steel the fins do not exchange have value without further treatment but prefheat as rapidly as desired. It is common to form erably it is sintered under heat and pressure to rel or sleeve tosecure a cylinder head. The homogeneous, strong character. The fins are threads are raised externally to keep the barrel pressed principally axially to make them thinner thin and uniform. There is also usually an anrather than smaller in diameter. chorage flange near the lower end of the cylinder. By this same action the fin structure is shrunk Consequently there is an annular groove in the and bonded to the cylinder barrel, thus forming a cylinder barrel where the fins are to be located. 15 good heat transfer medium for the cylinder.
Many methods have been proposed for pro- The fins may have any shape and dis siti n viding fins of good heat transfer material on the desired, either annular, spiral; axial or any other cylinder within the groove. It is an object of the, arrangement.
