Taking scroll compressor used in automotive air conditioning as research target ,the geome-try theory of the scroll with involutes of variable radii is selectively analyzed and the equation of scroll is established .Under the working conditions of gas temperature load and temperature load coupled with pressure load ,the stress and strain of the scroll with involutes of fixed and variable radii are compared and analyzed by using ANSYS software .The results show that the scroll with involutes of variable radii has better structural characteristics than the one with involutes of fixed radii and fits the complex working condition of compressor better when the refrigerating capacity is the same .
