Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning compressor technology, and in particular to a static disc intake structure for an air conditioning compressor for new energy vehicles. Background Technology
[0002] The scroll compressor in an automotive air conditioning system mainly consists of a moving plate and a stationary plate (collectively referred to as the scroll). The moving plate inserts into the stationary plate and drives the rotation center to rotate via an eccentric main shaft, thereby completing the compression process from intake to exhaust. Among these components, the design of the stationary plate intake structure directly affects the compressor's efficiency, noise, and reliability. Existing intake ports are unevenly distributed when gas enters the compression chamber, and eddies or backflow may occur in some areas, leading to localized over-compression or under-compression and increasing power consumption.
[0003] To address the shortcomings of existing technologies, it is necessary to design a static disc intake structure for air conditioning compressors in new energy vehicles. Utility Model Content
