Piston cooling fins

  •  The underside of the piston acts like a cooling area for the piston crown. In this area the cooling medium is circulated and the heat transfer takes place at the underside of the piston crown.
  • If the underside of the piston crown is provided with the fins, as the fins have better cooling effect with sufficiently thickened crown, we can have better cooling of the crown the thickened crown have more strength. 
  • At the same time the fin effect will be utilized for better cooling. 
  • Hence both, more strength and better cooling effect, is achieved by having a thicker crown and fins.
