发明名称 CENTRIFUGAL MACHINE
摘要 <P>PROBLEM TO BE SOLVED: To provide a centrifugal machine having a rotor with a sufficient cooling performance in a relatively simple structure and capable of reducing noise due to rotation and an air flow. <P>SOLUTION: This centrifugal machine is formed with independent air ducts respectively in a manner of being separated into an air duct for cooling the rotor 1 and an air duct for cooling an electric control part 16 and a motor 2. The air duct is disposed with a silencer formed of a shielding material, the air duct for cooling the rotor is disposed with a sound absorbing material, and the back face of the centrifugal machine is disposed with an outlet of the air duct for cooling the rotor. The back face of the centrifugal machine is further disposed with an outlet of the air duct for cooling the electric control part and the motor. <P>COPYRIGHT: (C)2009,JPO&INPIT
