AI Technical Summary
Existing scroll air compressors have difficulty effectively dissipating the heat generated during compression, causing the temperature of the moving scroll to rise and affecting the stable supply of compressed gas.
A partition plate is set inside the air compressor housing to form a cooling chamber. The main shaft drives the cooling fan to rotate. It connects to the outside through the air inlet and outlet holes, introduces cold air and removes heat. The airflow is guided to the bottom surface of the moving scroll by the shroud. Combined with the heat dissipation protrusions formed by the end cover and the stationary scroll, the heat dissipation effect is enhanced.
It achieves efficient heat dissipation of the air compressor, reduces the temperature of the moving scroll, improves the stable supply capacity of compressed gas, and enhances the overall structural strength and airflow.
