Study on Performance Optimization of Floating Fixed Scroll Plate of Scroll Compressor
Aiming at the problem that the temperature of the back of fixed scroll plate of the floating fixed scroll plate scroll compressor is too high and concentrated at the exhaust pipe,a floating fixed scroll plate back pressure mechanism with heat dissipation structure is proposed.The mass and energy exchange of the new mechanism was studied,the heat exchange process was analyzed,and the mathematical model of heat transfer in each cavity was given.The CFD simulation calculation of the new mechanism was carried out,and the temperature distribution of the back of fixed scroll plate under different external temperatures was obtained.Compared with the original floating fixed scroll plate back pressure mechanism,it can be concluded that the new mechanism effectively improves the problem of high temperature in the center of the back of fixed scroll plate,which makes the temperature distribution of the fixed scroll plate more uniform,and solves the problems of deformation,friction and wear and leakage caused by high temperature,and improves the reliability of compressors.
