[0022] The following will refer to figure 1 and figure 2 A first embodiment of the present invention will be described. In the first embodiment, figure 1 Blowers are typically used in vehicle air conditioners.
[0023] The vehicle air conditioner includes a blower for blowing air and an air conditioning unit for cooling and / or heating the air blown by the blower. The conditioned air of the air conditioning unit is blown into the passenger compartment of the vehicle. The blower is usually located on the front passenger seat side next to the driver's seat under the dashboard, which is at the front of the passenger compartment.
[0024] The blower includes a housing 1 made of resin so as to form an air passage 1 a through which air is blown into a passenger compartment. A fan 2 for generating an air flow in the air passage 1 a is located in the fan housing 1 . The fan 2 can be made of resin, for example. The fan 2 includes a plurality of blades around a rotation axis, and...

[0038] Next, a second embodiment of the present invention will be described with reference to FIG. 3 . In the second embodiment, the position of the motor control device 6 , the fixing method of the motor control device 6 and the fixing method of the heat sink 7 are different from those of the first embodiment described above. In the second embodiment, components having the same functions as those in the above-described first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.
[0039] In the second embodiment, as shown in FIG. 3 , the motor control device 6 is fixed to the heat sink 7 at a position separated from the yoke 31 . That is, the motor control device 6 is connected to the second plate 72 of the heat sink 7 at a position close to the heat sink 73 . Therefore, the heat generated by the motor control device 6 can be efficiently radiated into the air in the air passage 1 a via the heat sink 73 of the heat sink 7 . Even in the s...

[0042] A third embodiment of the present invention will be described below with reference to FIG. 4 . In the third embodiment, heat conduction fins (heat conduction fins) 9 are added to the structure of the blower. Other components having the same functions as those in the above-described first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.
[0043] The thermally conductive sheet 9 is made of a thermally conductive material having a higher thermal conductivity than the heat sink 7 , and the heat sink 7 is tightly bonded to the thermally conductive sheet 9 . The motor control device 6 is attached to the thermally conductive sheet 9 so as to be tightly connected to the thermally conductive sheet 9 . Therefore, the heat generated by the motor control device 6 can be effectively transferred to the second board 72 having the cooling fins 73 via the heat conducting fins 9 . As a result, the heat generated by the motor control device 6 ...
