Diagaram showing the difference of water and air cooling

This example from one of the world’s leading drives manufacturers shows the sizing issue:

 

  • An air cooled unit is 50% bigger in size when compared to a water cooled unit, or
  • Similar sized air cooled unit is 66% in nominal power of that of a water cooled unit
