Abstract
An electronic device includes a base being heat conductive and having a first main surface to which an electronic component is attachable, and a plurality of fins attached to a second main surface of the base and extending in a first extension direction and in a second extension direction. The plurality of fins dissipate heat transferred from the electronic component through the base to ambient air. The electronic device further includes one or more air guides each including a first member surrounding the plurality of fins and having a main surface intersecting with the first extension direction, and a second member attached to the first member and having a main surface extending away from centers of the plurality of fins in the first extension direction.
Claims23
An electronic device, comprising:
- a base being heat conductive and having a first main surface to which an electronic component is attachable;
- a plurality of fins spaced from one another and attached to a second main surface of the base, the second main surface being opposite to the first main surface, the plurality of fins extending in a first extension direction along the second main surface and in a second extension direction away from the second main surface, the plurality of fins being configured to dissipate heat transferred from the electronic component through the base to ambient air;
- and
- one or more air guides each including a first member surrounding the plurality of fins, having a main surface intersecting with the first extension direction, and having a plurality of slits fitted with ends of the plurality of fins distant from the base, and a second member attached to the first member and having a main surface extending away from centers of the plurality of fins in the first extension direction.
