Abstract

A heat sink according to one embodiment of the present invention includes: a base portion having a first surface and a second surface which oppose each other; at least one heat dissipating fin extending vertically from the first surface, each of the at least one heat dissipating fin having an insertion groove extending from an end portion thereof toward the base portion, and a first fin portion and a second fin portion which are separated by the insertion move; and a connector included in the base portion, the connector being above the insertion groove in plan view, and the connector being configured to electrically connect a first heat generating component to be inserted into the insertion groove from a side of the first surface and a second heat generating component to be disposed on a side of the second surface.

First claim

The invention claimed is:

1. A heat sink comprising:
a base portion having a first surface and a second surface which oppose each other;
at least one heat dissipating fin extending vertically from the first surface, each of the at least one heat dissipating fin having an insertion groove extending from an end portion thereof toward the base portion, and a first fin portion and a second fin portion which are separated by the insertion groove; and
a connector included in the base portion, the connector being above the insertion groove in plan view, and the connector being configured to electrically connect a first heat generating component to be inserted into the insertion groove from a side of the first surface and a second heat generating component to be disposed on a side of the second surface, wherein
the connector has:
a third surface on the side of the first surface;
a fourth surface on the side of the second surface, the fourth surface opposing the third surface;
a first outlet extending from the third surface toward the fourth surface, a first connecting terminal of the first heat generating component being attachable and detachable into and from the first outlet; and
a second outlet extending from the fourth surface toward the third surface, a second connecting terminal of the second heat generating component being attachable and detachable into and from the second outlet,

the base portion has a slide groove extending parallel to the insertion groove, the base portion being above the insertion groove in plan view, and
the connector is slidable in the slide groove in parallel to the insertion groove.

2. The heat sink according to claim 1 , further comprising:
a plurality of connectors including the connector, the plurality of connectors being included in the base portion, and the plurality of connectors being above the insertion groove in plan view.

3. The heat sink according to claim 1 , wherein
the slide groove includes a first slide groove extending from the second surface toward the first surface, and a second slide groove extending from the first surface toward the second surface and connecting the first slide groove and the insertion groove,
both end portions, in an extending direction, of the first slide groove, and both end portions, in an extending direction, of the second slide groove are positioned inside the first surface or the second surface of the base portion in plan view, and
a groove dimension of the second slide groove is smaller than a groove dimension of the first slide groove.

4. The heat sink according to claim 1 , wherein
the connector has a plurality of second outlets including the second outlet, the plurality of second outlets extending from the fourth surface toward the third surface,
the plurality of second outlets including a first set of three second outlets aligned parallel to an extending direction of the slide groove, and a second set of three second outlets aligned vertical to the extending direction of the slide groove,
the first set and the second set have a common center second outlet,
the second heat generating component has three second connecting terminals including the second connecting terminal, and
the three second connecting terminals are attachable and detachable into and from any of the first set and the second set.

5. A heat sink comprising:
a base portion having a first surface and a second surface which oppose each other;
at least one heat dissipating fin extending vertically from the first surface, each of the at least one heat dissipating fin having an insertion groove extending from an end portion thereof toward the base portion, and a first fin portion and a second fin portion which are separated by the insertion groove; and
a connector included in the base portion, the connector being above the insertion groove in plan view, and the connector being configured to electrically connect a first heat generating component to be inserted into the insertion groove from a side of the first surface and a second heat generating component to be disposed on a side of the second surface, wherein
the connector has:
a third surface on the side of the first surface;
a fourth surface on the side of the second surface, the fourth surface opposing the third surface;
a first outlet extending from the third surface toward the fourth surface, a first connecting terminal of the first heat generating component being attachable and detachable into and from the first outlet; and
a second outlet extending from the fourth surface toward the third surface, a second connecting terminal of the second heat generating component being attachable and detachable into and from the second outlet,

the connector extends parallel to the insertion groove in plan view, and
the connector has:
a plurality of first outlets including the first outlet, the plurality of first outlets being aligned parallel to the insertion groove on the third surface in plan view, and
a plurality of second outlets including the second outlet, the plurality of second outlets being aligned in a grid on the fourth surface in plan view.

6. The heat sink according to claim 5 , wherein
the first connecting terminal of the first heat generating component is attachable and detachable into and from any of the plurality of first outlets, and
the second connecting terminal of the second heat generating component is attachable and detachable into and from any of the plurality of second outlets.

7. The heat sink according to claim 5 , wherein
the plurality of second outlets including a first set of three second outlets aligned parallel to an extending direction of the connector, and a second set of three second outlets aligned vertical to the extending direction of the connector,
the second heat generating component has three second connecting terminals including the second connecting terminal, and
the three second connecting terminals are attachable and detachable into and from any of the first set and the second set.

8. The heat sink according to claim 5 , wherein both end portions, in an extending direction, of the connector are positioned inside the first surface or the second surface of the base portion in plan view.

9. A heat dissipating structure comprising:
a heat sink comprising
a base portion having a first surface and a second surface which oppose each other, and
at least one heat dissipating fin extending vertically from the first surface, each of the at least one heat dissipating fin having an insertion groove extending from an end portion thereof toward the base portion, and a first fin portion and a second fin portion which are separated by the insertion groove;

a first heat generating component to be inserted into the insertion groove from a side of the first surface;
