路を形成したところに特徴を有する。[Constitution of the Invention] (Means for Solving the Problems) The duct ventilation fan of the present invention has heat insulation along an inner peripheral surface portion thereof inside a main body frame having an intake port on a lower surface and an exhaust port on a side surface. A body is provided, and a double-wing fan having a wing portion on the intake side and a wing portion on the opposite side of the intake port and a motor for driving the fan are disposed, and the heat-insulating body is provided with the fan from the intake port. It is characterized in that a ventilation path is formed to ventilate the wings on the side opposite to the intake port of the fan.
