A ventilator is provided to reduce noise of a blower transmitted to the outside by forming a curved route from an air inlet hole to the blower using a partition member. A ventilator includes a case(110), a blower(130), an inverter(140), and a radiator(152). The case has a receiving part(111) and an air inlet hole to introduce air into the receiving part. The blower is arranged in the receiving part of the case and has a motor and an impeller connecting to the motor, and compresses the air flowing from the air inlet hole and blows the air to the outside of the receiving part. The inverter is arranged in the receiving part of the case and is electrically connected to the blower to control the speed of the impeller. The radiator is connected to a cooling water channel in the blower to cool the blower. The radiator is arranged between the air inlet hole and the blower. The radiator emits heat included in the cooling water heated through the cooling water channel to the air flowing from the air inlet hole.
