Problems solved by technology
Their common disadvantage is that there is a single mapping relationship between the profile and the performance target, which relies too much on the specific expression form of the profile equation, and the specific model corresponds to the specific profile, which makes the modeling process of various profiles too complicated. complex and varied
Therefore, the design flexibility is relatively poor, the pertinence is too strong, the conclusions derived are not universal and universal, and the calculation efficiency is low
In addition, one of the main problems of traditional molded lines is that the compression process is very slow, and it takes many turns to obtain a high compression ratio molded line, and the structural size is large and the leakage rate increases sharply
As for a modified profile proposed by Japan, it uses two arcs for correction, that is, Perfect Mesh Profile or PMP profile, but because the profile segment at the root is in a high-pressure area, its strength is low

The invention relates to a scroll compressor with equal wall thickness and high compression ratio, which comprises two interlocking fixed scrolls and a movable scroll. The scroll wraps whose angles are staggered by 180° are interlocked up and down to form a compression chamber. The function expression of the universal vortex profile of the function is: s(φ)=C0+C1φ+C2φ2+C3φ3+…+Ckφk (1) where s——profile arc function φ——profile tangential angle parameter Ck - profile coefficient parameter k - number of series items n - natural number. Compared with the traditional involute scroll compressor, the constant wall thickness and high compression ratio scroll compressor of the present invention has a large compression ratio and high efficiency. Compared with the traditional involute and other existing optimized profiles, the compression than doubled.
Description
technical field [0001] The invention relates to a novel scroll compressor, in particular to a scroll compressor with equal wall thickness and high compression ratio. Background technique [0002] Scroll compressor is a precision machine used for compression and refrigeration. Since its working principle was discovered by Cruex in 1905, due to the constraints of molding line processing technology, until the advancement of numerical control processing technology in the 1970's, commercial applications began to appear on a large scale . Since then, applications have grown in popularity. Soon, people realized the inherent characteristics of scroll compressors, such as less moving parts, low noise, low vibration, high efficiency and high reliability, and invested a lot of research. Today, scroll compressors are widely used in small and medium-sized air conditioning and refrigeration units. [0003] Scroll compressors are machines based on the working principle of cavity volume ...
