Abstract
A heat-dissipating structure including a heat sink having a recessed portion on a first surface facing a heat generator, the recessed portion having a side surface; a heat block fit into the recessed portion, the heat block having a bottom surface and a side surface; and thermally conductive grease in contact with both of the side surface of the recessed portion and the side surface of the heat block, wherein the bottom surface of the heat block is in contact with the heat generator.
Claims4
A heat-dissipating structure comprising:
- a heat sink having a recessed portion on a first surface facing a heat generator, the recessed portion having a bottom surface and a side surface;
- a heat block fit into the recessed portion, the heat block having a top surface, a bottom surface, and a side surface;
- thermally conductive grease in contact with both of the side surface of the recessed portion and the side surface of the heat block;
- and
- a thermally conductive sheet in contact with both of the bottom surface of the recessed portion and the top surface of the heat block,
- wherein the bottom surface of the heat block is in contact with the heat generator.
A method for manufacturing a heat-dissipating structure comprising a heat sink having a recessed portion on a first surface facing a heat generator, and a heat block fit into the recessed portion, the method comprising:
- applying thermally conductive grease to at least one of a side surface of the recessed portion and a side surface of the heat block;
- and
- fitting the heat block into the recessed portion while rotating the heat block about a central axis of the heat block with a thermally conductive sheet provided between a bottom surface of the recessed portion and a top surface of the heat block such that the heat sink and the thermally conductive sheet are in contact with each other and the thermally conductive sheet and the heat block are in contact with each other.
