1. A cooling apparatus that feeds cooling air to a heat exchanger of an electronic apparatus, the cooling apparatus comprising:
a fan; and
a body frame configured to hold the fan,
wherein the fan includes a blade configured to be housed in a casing and to rotate about a fan shaft, and discharges air drawn from a fan inlet opening of the casing into a fan exhaust opening of the casing, wherein the fan inlet opening surrounds the fan shaft, and wherein the fan exhaust opening is provided in a tangent line direction of a rotational direction of the blade,
wherein the body frame includes an air-leading duct configured to feed, to the heat exchanger, the air discharged into the fan exhaust opening,
wherein a first direction is a direction in which air is fed from the air-leading duct to the heat exchanger, a first plane is a plane orthogonal to the first direction, and a second plane is a plane parallel to the first direction, and
wherein the fan is tilted by a first tilt relatively to the first plane so that, in the first direction, the fan exhaust opening is closer to the heat exchanger than the blade, and is tilted by a second tilt about the fan shaft so that in a view from the first direction, the fan exhaust opening is tilted relatively to a direction parallel to the second plane.
