Electronic device and electronic-device housing
View Patent ↗An electronic-device housing stores an electronic circuit and a cooling fan. The electronic-device housing includes a first surface having at least one opening to release heat outside. At least one projected portion projects toward an outside of the electronic-device housing, and when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface and the projected portion comes into contact with the installation surface, a rotation moment acting on a gravity center of the electronic-device housing acts in a direction where the rotation moment causes the first surface to move away from the installation surface.
1. An electronic-device housing comprising:
a first surface having at least one opening to release heat outside, and at least one projected portion that projects away from the electronic-device housing,
wherein when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface, and the projected portion comes into contact with the installation surface, a curved surface of the projected portion allows a force to act on a gravity center of the electronic-device housing so that the electronic-device housing rotates and the first surface moves away from the installation surface, and
wherein when the electronic-device housing is installed on the installation surface so that the first surface is opposed to the installation surface, and the projected portion comes into contact with the installation surface, the gravity center of the electronic-device housing exists outside a virtual solid formed vertically above a surface formed by connecting the projected portion in contact with the installation surface, and each end portion of the first surface in contact with the installation surface.
2. An electronic-device housing that is able to store therein an electronic circuit and a cooling fan, the electronic-device housing comprising:
a first surface having at least one opening to release heat outside, and at least one projected portion that projects away from the electronic-device housing,
wherein when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface, and the projected portion comes into contact with the installation surface, a curved surface of the projected portion allows a force to act on the gravity center of the electronic-device housing so that the electronic-device housing rotates and the first surface moves away from the installation surface,
the electronic-device housing has a rectangular parallelepiped shape having a pair of side surfaces, a bottom surface, an upper surface, a front surface, and a back surface,
the first surface corresponds to one side surface of the pair of side surfaces, and
at least one length of a height of the electronic-device housing corresponding to a length between the upper surface and the bottom surface, and a depth of the electronic-device housing corresponding to a length between the front surface and the back surface is not more than a width of the electronic-device housing corresponding to a length between the pair of side surfaces, and
wherein the cooling fan is arranged so as to be opposed to the one side surface inside the electronic-device housing,
the one side surface has a first opening for ventilation in an area opposed to the cooling fan, and
when the electronic-device housing is installed with the one side surface at a bottom, an apex of the projected portion comes into contact with the installation surface at a point.
3. The electronic-device housing according to claim 1 , wherein the projected portion includes a plurality of projected portions, and the plurality of projected portions are arranged in a line.
4. An electronic-device housing comprising:
a first surface having at least one opening to release heat outside, and at least one projected portion that projects away from the electronic-device housing,
wherein when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface, and the projected portion comes into contact with the installation surface, a curved surface of the projected portion allows a force to act on a gravity center of the electronic-device housing so that the electronic-device housing rotates and the first surface moves away from the installation surface,
wherein the electronic-device housing with the projected portion cannot stand on its own when the electronic-device housing is installed with the first surface as a bottom.
5. The electronic-device housing according to claim 2 , wherein when the electronic-device housing is installed with one side surface at the bottom, a gravity center axis is presumed as vertically passing the gravity center of the electronic-device housing, an apex of the projected portion exists at an upper surface side with respect to the gravity center axis.
6. The electronic-device housing according to claim 2 , wherein the upper surface of the electronic-device housing includes a second opening for ventilation, and
wherein the cooling fan is arranged inside the electronic-device housing so as to be parallel to, spaced at a predetermined distance from, and opposed to the one side surface of the electronic-device housing, and
the second opening is provided in the predetermined distance from the one side surface of the electronic-device housing.
7. An electronic device comprising:
the electronic-device housing according to claim 1 ;
an electronic circuit stored inside the electronic-device housing; and
a cooling fan stored inside the electronic-device housing.
