Abstract
The invention relates to a heat sink (1) having a main body (2) and a plurality of carbon-nanostructure-based fibres (CNB, 3), more particularly carbon nano tubes (CNT, 4) or graphene fibres, of which at least some are attached to the main body (2). According to the invention, the fibres (3, 4), by adhering to or supporting one another, form a volume structure (12), more particularly in the manner of cotton wool, felt or a spun yarn, or the fibres (3, 4) form loops (6) or a three-dimensional woven fabric.
Claims19
A heat sink (1) comprising:
- a main body (2);
- a plurality of carbon nanostructure-based fibers (CNB, 3) of which at least some are secured to the main body (2) for heat transfer;
- a counterbody (8) which is a distance away from the main body (2) and has at least some of the fibers (3) secured thereto;
- and
- at least one support structure (14, 15) which supports the fibers (3, 4);
- wherein the at least one support structure (14, 15) is grid-shaped and assists the securing to the main body (2) and/or the counterbody (8), and
- wherein, due to mutual adhesion or support the fibers (3) form a volume structure (12), or wherein the fibers (3) form loops (6) or a three-dimensional fabric.
A heat sink (1) comprising:
- a main body (2);
- and
- a plurality of carbon nanostructure-based fibers (CNB, 3) of which at least some are secured to the main body (2) for heat transfer;
- wherein at least some of the fibers (3) extend from a sheetlike fiber basis (11, 13) formed by the fibers (3) and/or further carbon nanostructure-based fibers (CNB, 3);
- wherein the fiber basis (11, 13) is in the form of a fabric;
- and
- wherein due to mutual adhesion or support the fibers (3) form a volume structure (12), or wherein the fibers (3) form loops (6) or a three-dimensional fabric.
A heat sink (1) comprising:
- a main body (2);
- a plurality of carbon nanostructure-based fibers (CNB, 3) of which at least some are secured to the main body (2) for heat transfer;
- and
- at least one support structure (14, 15) which supports the fibers (3, 4);
- wherein the at least one support structure (14, 15) is made of metal and/or of further carbon nanostructure-based fibers (CNB, 3);
- and
- wherein due to mutual adhesion or support the fibers (3) form a volume structure (12), or wherein the fibers (3) form loops (6) or a three-dimensional fabric.
