Abstract
A heat sink (2) has a base (4) having a first surface (4a) thermally connected to a heat producing body and also has fins (6a-6d) each having through-holes (8), the fins being supported by a second surface (4b) of the base (4) and arranged in a predetermined direction. The base (4) and the fins (6a-6d) are integrally formed of a porous material (lotus-type porous material). The heat sink (2) is placed in a duct (80). It is preferable that the width (W) of the heat sink (2) is substantially equal to or less than 10 mm.

1-15. (canceled)
A heat sink comprising:
- a base having a first surface which is thermally connected to a heat producing component;
- and
- a plurality of fins supported by a second surface of the base which is opposite from said first surface and arranged in a predetermined direction, each fin having a plurality of through-holes;
- wherein the base and the plurality of fins are integrally formed from a porous material.
A heat sink comprising:
- a base having a first surface which is thermally connected to a heat producing component;
- a plurality of fins supported by a second surface of the base which is opposite from said first surface and arranged in a predetermined direction, each fin having a plurality of through-holes;
- and
- a side wall which supports the plurality of fins through side surfaces of the respective fins adjacent to their surfaces bonded to the base;
- wherein the side wall and the plurality of fins are integrally formed from a porous material.
A heat sink comprising:
- a plurality of fins which are bonded to an outer base connected thermally to a heat producing component and are arranged in a predetermined direction, each fin having a plurality of through-holes;
- and
- a side wall which supports the plurality of fins through side surfaces of the respective fins adjacent to their surfaces bonded to the outer base;
- wherein the side wall and the plurality of fins are integrally formed from a porous material.
