Abstract

The thermal deformation of scrolls significantly affects the hermetic property between scrolls, and thus affects the efficiency of the scroll compressor. An accurate temperature distribution on scrolls must be obtained before the thermal deformation of scrolls can be analyzed. The temperature inside real scrolls in the steady state was experimentally measured. Then, reasonable thermal boundary conditions were applied to perform a heat transfer analysis to determine the temperature distribution on scrolls. Then, the distribution of the thermal deformation on scrolls was analyzed. Finally, fixed and orbiting scrolls were engaged with each other and analyses were performed to determine the stress and deformation distributions at the orbital angle that the maximum compression ratio happens.
