Abstract
A duct structure includes: a duct member, wherein the duct member includes: an introduction portion, an opening communicating with a fan, a curved flow path having the opening and extending in a curved shape, a rectifying portion rectifying the cooling air flowing through the curved flow path, and a guide portion provided in the opening and guiding the cooling air flowing through the curved flow path to the opening, a sound absorbing material is provided in the curved flow path, the guide portion includes a guide wall, and an inlet is disposed at a position that is not visible in a plane perpendicular to a rotation axis direction of the fan when viewed in a direction perpendicular to a virtual line connecting one side end portion and the other side end portion of the guide wall from the opening in a straight line.
Claims5
A duct structure connected to a fan that blows cooling air to a battery mounted on a vehicle, the duct structure comprising:
- a duct member connected to the fan, wherein
- the duct member includes:
- an introduction portion introducing the cooling air,
- an opening communicating with the fan,
- a curved flow path having the opening and extending in a curved shape in a plane perpendicular to a rotation axis direction of the fan,
- a rectifying portion extending in a curved shape along the curved flow path and rectifying the cooling air flowing through the curved flow path, and
- a guide portion provided in the opening and guiding the cooling air flowing through the curved flow path to the opening,
- a sound absorbing material is provided in the curved flow path,
- the guide portion includes a guide wall erected from a part of an outer edge portion of the opening and receiving the cooling air flowing through the curved flow path, and
- an inlet of the curved flow path connected to the introduction portion is disposed at a position that is not visible in the plane perpendicular to the rotation axis direction of the fan when viewed in a direction perpendicular to a virtual line connecting one side end portion and the other side end portion of the guide wall from the opening in a straight line.
