Abstract
A heatsink apparatus has a construction which produces a high heat-radiating effect even if the apparatus is designed to be compact or to have a small thickness. The heatsink apparatus includes a base plate to which a heat-generating body may be connected, a heat-radiating portion, and a fan mounted on the base plate. The heat-radiating portion includes plate-like members having main surfaces facing the base plated, and a fan mounted on the base plate.
Claims21
A heatsink apparatus comprising a base plate, a heat radiating portion, and blowing means mounted on said base plate, said heat radiating portion including plate-like members having main surfaces facing said base plate, wherein:
- said radiating portion surrounds said blowing means except a part of said blowing means, and
- each of said plate-like members has substantially a U-shape.
A heatsink apparatus comprising a base plate, a heat radiating portion, and blowing means mounted on said base plate, said heat radiating portion including plate-like members having main surfaces facing said base plate, wherein:
- said radiating portion surrounds said blowing means except a part of said blowing means, and
- each of said plate-like members has substantially an L-shape.
A heatsink apparatus comprising a base plate;
- a heat radiating portion, blowing means mounted on said base plate said heat radiating portion including plate-like members having main surfaces facing said base plate;
- pillar-like members extending substantially perpendicularly from said base plate, said plate-like members being mounted on said pillar-like members;
- and a heat transfer member that is mounted on a side of said base plate opposite to a side thereof from which said pillar-like members extend, said heat transfer member being mounted thereon in an opposed relation to said pillar-like members.
A heatsink apparatus comprising a base plate;
- a heat radiating portion;
- blowing means mounted on said base plate, said heat radiating portion including plate-like members having main surfaces facing said base plate;
- pillar-like members extending substantially perpendicularly from said base plate, said plate-like members being mounted on said pillar-like members;
- and a heat transfer member that is mounted on a side of said base plate opposite to a side thereof from which said pillar-like members extend, said heat transfer member being mounted thereon in a relation not opposed to said pillar-like members.
A heatsink apparatus comprising a base plate;
- a heat radiating portion;
- blowing means mounted on said base plate, said heat radiating portion including plate-like members having main surfaces facing said base plate;
- pillar-like members extending substantially perpendicularly from said base plate, said plate-like members being mounted on said pillar-like members;
- and a heat transfer member that is mounted on a side of said base plate opposite to a side thereof from which said pillar-like members extend, said heat transfer member being mounted thereon in a relation opposed to some of said pillar-like members and not opposed to the other of said pillar-like members.
A heatsink apparatus comprising a base plate;
- a heat radiating portion;
- blowing means mounted on said base plate, said heat radiating portion including plate-like members having main surfaces facing said base plate;
- and a plurality of pillar-like members extending substantially perpendicularly from said base plate, said pillar-like members including at least one pillar-like member having a diameter larger than a diameter of another of said pillar-like members.
A heatsink apparatus comprising a base plate, at least one pillar-like member extending substantially perpendicularly from said base plate, a plurality of plate-like members mounted on said pillar-like member, and blowing means mounted on said base plate, said plate-like members being stacked together with a predetermined space defined therebetween and having main surfaces facing said base plate, wherein
- among a space between said base plate and one of the plate-like members adjacent to said base plate and a space between any one of two adjacent plate-like members, at least one of said spaces is larger than at least one of the other spaces.
