  • Publication number: 20210320555
    Abstract: A frame included in an electronic motor has an inflow hole that allows outside air to flow in an interior of the electric motor and an outflow hole that allows the outside air having flowed in to flow out of the electric motor. The electric motor includes a first partition member forming a first ventilation path between the first partition member and the frame, and a second partition member forming a second ventilation path between the second partition member and the frame. In addition, the stator has a third ventilation path penetrating through the stator from one end to another end of the stator in a direction of a rotational axis and configured to communicate with the first ventilation path and the second ventilation path.

  • Patent number: 10752263
    Abstract: A vehicular cooling device includes an opening, a discharge port, an air channel, and a fan. The opening is formed in a surface parallel to a travelling direction of a vehicle. The discharge port is formed in a surface of the housing and connected to the opening via the air channel. The fan is provided inside the air channel. First blockers are spaced apart in the travelling direction in the opening. Each first blocker extends in a direction perpendicular to both the travelling direction and an inflow direction of the outside air, and includes first and second members. The first member is a plate-like member having a main surface intersecting the travelling direction. The first member and the second member are symmetric with respect to a plane perpendicular to the travelling direction, and have a travelling-direction spacing therebetween that increases along the inflow direction of the outside air.
