This paper presents a clearance Analysis using 3D-CAD system on a Stirling refrigerator. A prototype Stirling refrigerator employing helium as a working fluid has been investigated to see whether the freon free machine be a viable alternative for the current household refrigerator. It is modify to the most suitable working space by reducing a dead volume. But the working space is a complex form because, the working space composes a displacer and a compression piston. Using 3D-CAD system does the modeling of a Stirling refrigerator. And it is made that a clearance in each part becomes proper. The displacer form and an inside cylinder were modified. These results reveal that the dead volume can reduce about 10.28 m^3 And a theory cooling capacity may improvement about 28.41 W.
