Abstract
In an electronic device having a heat sink, the heat sink includes a flat-plate-shaped base and fins protruding from one surface of the base and extending substantially in the direction of gravity in a state where the electronic device is mounted on an apparatus. Each of the fins has a first inclined portion on a lower surface thereof in the direction of gravity, and the first inclined portion is inclined downward in the direction of gravity toward the base. The base has a second inclined portion on a lower surface thereof in the direction of gravity, and the second inclined portion is inclined with respect to the horizontal direction when the base is viewed from a side where the fins are provided.
Claims5
An electronic device having a heat sink, wherein:
- the heat sink includes:
- a flat-plate-shaped base;
- and
- fins protruding from one surface of the base and extending substantially in a direction of gravity in a state where the electronic device is mounted on an apparatus;
- a first inclined portion defined on a lower surface of each of the fins in the direction of gravity, the first inclined portion being configured to incline downward in the direction of gravity toward the base;
- and
- a second inclined portion defined on a lower surface of the base in the direction of gravity, the second inclined portion being configured to incline with respect to a horizontal direction when the base is viewed from a side where the fins are provided, wherein the second inclined portion includes two inclined portions formed on either side of a central portion of the base.
