This project investigates the thermal performance optimization of vehicle-mounted air-cooled oil-free lubricated scroll compressors. Scroll compressors face difficulties in heat dissipation during compression, making them unsuitable for long-term uninterrupted operation, which is a technical bottleneck in the field of vehicle applications. The project aims to address issues such as excessive gas temperature rise due to insufficient heat dissipation from the scroll compressor, leading to increased shaft power, high temperatures affecting auxiliary bearings, thermal coupling impacting the precision of the scroll profile, reduced system reliability, and large system size. By studying the heat transfer characteristics of the scroll compressor, reducing the problem of out-of-control temperature rise during compression at the source and process level, and shifting the compression process of the air-cooled oil-free lubricated scroll compressor towards isothermal compression, the project aims to improve the compression efficiency of the system. Additionally, by researching the deformation of the scroll line under the influence of temperature fields, the project seeks to solve the deformation issue caused by thermal coupling at high temperatures, thereby reducing additional frictional heat. And by referring to the clearance-compensated profile correction method of scroll compressors, deformation areas that are significantly affected by thermal coupling are corrected to improve system reliability. The implementation of this project has resulted in independent intellectual property rights, with one invention patent application and one utility model patent application. The methods and measures proposed in this project for addressing the temperature rise of air compressors have reduced the gas temperature and terminal exhaust temperature during the compression process of scroll air compressors, decreased the specific power of the compressor, energy saving and emission reduction, and improved system reliability, increasing market attractiveness. By solving the technical bottleneck of scroll air compressor temperature rise, it is conducive to the miniaturization of systems and helps promote the application of air-cooled oil-free lubricated scroll compressors in fields such as rail transit and automotive fuel cells, advancing industrial upgrading and replacement.
