Abstract
A cooling unit can be downsized. Air is taken in through an intake port, and heat is discharged from a heat source through an exhaust port. A heat transport unit, forming a part of a cooling fan or is substantially in contact with it, has a first region which has one end facing the heat source and another end having a through hole which air taken in or air to be discharged passes through, and in which air passes through the through hole to perform heat exchange with the air in an inner wall of the through hole. The cooling fan has an intake opening and an exhaust opening. The through hole has an intake through hole and/or an exhaust through hole. Air passes through the intake port, the intake through hole, the intake opening, the exhaust opening, the exhaust through hole, and the exhaust port in this order.
