Air compression system and cooling structure thereof

摘要

An air compression system (1) includes an air compression device (10) and a cooling structure (20). The air compression device (10) includes a liquid-cooled motor (11) and a compressor (12). The cooling structure (20) includes a radiator (21), a cooler (23), a first liquid conveying tube (24), a second liquid conveying tube (25), a third liquid conveying tube (26), a fourth liquid conveying tube (27), and a cooling liquid (28). The radiator (21) interconnects the compressor (12) for cooling a lubricating liquid (17) in the compressor (12), the first liquid conveying tube (24) interconnects the radiator (21) and the cooler (23), the second liquid conveying tube (25) interconnects the radiator (21) and the cooler (23), the third liquid conveying tube (26) interconnects the liquid-cooled motor (11) and the cooler (23), the fourth liquid conveying tube (27) interconnects the liquid-cooled motor (11) and the cooler (23), and the cooling liquid (28) is filled into the cooler (23), so as to reduce the space occupied by the cooling structure (20).
