Modification for scroll wrap height of a scroll compressor

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
In order to obtain better axial hermetic seal of scroll compression chambers and hence a better performance for a scroll compressor, two modification methods for scroll wrap height are proposed based on the axial deformation of the scroll wrap. First, the design modification, which allows the scroll wrap height and its dimensional tolerances to be ...

Temperature and thermal deformation analysis on scrolls of scroll compressor

Applied Thermal Engineering, 2005
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.

Simulation of Radial Deformation for Orbiting Scroll Wrap in a Scroll Compressor

Applied Mechanics and Materials, 2011
Based on assumptions and tests of the discharge temperatures land pressures for a scroll compressor, a simulation of radial deformations of the orbiting scroll wrap is performed. All simulations show that the radial deformation of scroll wrap varies complicatedly in outer part. Although the deformations are controlled by the temperature of scroll wrap,
