Abstract: An electronic device includes a first unit and a second unit including a display device. The first unit includes a housing, a blower device, and an exhaust path. The exhaust path includes a first member, a second member, a third member, and a partition member. The second member faces the second unit positioned at an opened position. The third member faces the first member and extends from an end of the second member far from the first member in a direction away from the first member as the third member is away from the second member. The partition member is disposed at an end close to the second member in a first direction and between the first member and the third member, and extends along the first direction. The second member includes a first exhaust hole. The third member includes a second exhaust hole larger than the first exhaust hole.

Abstract: A heat dissipating structure of the present disclosure is a heat dissipating structure provided inside a housing, the heat dissipating structure including: a blower that blows air; a heat dissipator including a heat dissipating blow passage through which air from the blower flows; a heat transmitter arranged on the heat dissipator and transferring heat generated by a heat source to the heat dissipator; and a branch blow passage provided between the housing and the heat transmitter and branching from the heat dissipating blow passage. The heat dissipating blow passage includes a branch inlet positioned between the heat transmitter and the blower. The branch blow passage branches from the branch inlet of the heat dissipating blow passage.
