Patent ID: 7405930

Claim:
An electronic apparatus comprising: a housing having a suction port and an exhaust port; a partition wall partitioning an interior of the housing with a first chamber and a second chamber, the first chamber accommodating therein a circuit component which generates heat, the suction port and the exhaust port being open to the second chamber; a heat transfer member passing through the partition wall to transfer a heat of the circuit component from the first chamber to the second chamber; a fan disposed in the second chamber, and the fan discharging from the exhaust port out of the housing air suctioned through the suction port so as to emit the heat of the circuit component transferred to the second chamber; and a sealing member sealing a part at which the heat transfer member pass through the partition wall, wherein the fan has a impeller, a motor that rotates the impeller, and a casing that accommodates the impeller and the motor therein, wherein the casing serves as the partition wall, and wherein the motor further includes: a waterproof case that accommodates a stator; a rotor; a rotary shaft being rotatably supported through a bearing by the waterproof case, and the rotary shaft protruding outside the waterproof case, and the rotary shaft being connected to the impeller; and a sealing member liquid-tightly sealing a part where the rotary shaft passes through the waterproof case.
