Abstract (en)
[origin: EP1479335A2] By arranging a power device or devices on the outer face of a partition wall such as a linking portion (flange portion) constituting a flow passage between the exhaust port (22) of a centrifugal fan (4) and a motor (2), the power device or devices can be efficiently cooled without disturbing the air flow in an air channel within a case (5) and without increasing in pressure loss of the air channel. Moreover, the power device or devices are not affected by heat from the motor since they are positioned farther upstream than the motor (2), in the air flow from the centrifugal fan (4).
