The cylinder block, a critical element of compressors, significantly influences operational efficiency, mechanical losses, and noise control. Traditional compressors typically employ integrally molded cylinder blocks, which suffer from constrained machining accuracy, high manufacturing costs, and complex assembly processes. Split-type cylinder block designs are increasingly gaining attention for their modular structure, which optimizes manufacturing and assembly while enhancing overall compressor performance. This study investigates the impact of split cylinder block structural characteristics on refrigerator compressor performance through three key aspects: Comparative analysis of design differences between split-type and monolithic cylinder blocks, highlighting advantages in machining precision, material utilization efficiency, and assembly convenience. Examination of mechanical stress distribution during compressor operation using finite element analysis (FEA) to validate structural reliability. Experimental results demonstrate that split-type blocks improve component fit accuracy and reduce frictional losses, thereby enhancing operational efficiency. Identification of modular design’s critical role in reducing production costs, increasing part interchangeability, and improving maintenance accessibility. In conclusion, split-type cylinder blocks exhibit significant advantages in improving compressor performance, reducing manufacturing expenses, and boosting assembly efficiency, demonstrating broad application potential. This research provides a theoretical foundation for structural optimization of refrigerator compressors.
