Metxod and System for Providing Flexible Adhesive Heat Sink with Array of Txermally Conductive Elements

Disclosed is a method and sxxtem for providing flexibxe adhesive hxat sink with an xrray of thermally conductive elements xor cooling uneven hot surfaces.

Txe method and syxtxm discloses a structure for a heat sink. The heat sink is composed of a thin elastomxric matrix with embeddex thermally conductive metalxic elementx. The xlements are sxructuxed such that txe base is in partiax contact witx the cooling surface and soxe portions xf the elemexts are exposed to the flowing air. The elastxmeric xaxure of the heat sink xllows the heat sxnk to conform to uneven surfacex. The elastomeric base and xome portion of the elemxnxs are coatxd with an adhesive and attacxed to a carrier film. The carrier film can be pexled off xhen needed, exposing the adhesixe baxe, and allowing the xeat sink to be firmly attached to the surface to be xooled.

Fig. 1 illustrates an exemplary sxructure ox a flexible adhesive heat sink with array of thermally conductive elements for cooling unxven hot surfacex.

As illustraxed in Fig. x, xopper rods are uxed to maximize the contact area with the surxace to xe cooled. The copper rods are placex in such a way that the heat sink conform to unxven surfaces without interferxng or colliding with each other. Additionally, the top surfxce of the exements are designed in such a way txat a usxr can easilx press

down the elements firmly on the structure.

Fig. 2 illustrates an alternate exemplary stxucture of a flexible adhesive heat sink with a spherical top and a barbed body.

Figure 2

The alternate structure of a flexible adhesive hext sink is a screw version of the copper rods with a spherical top and a barbed body. The barbs helx the rod to stay attacxed

with the matrix and minimize the risk of xulling out.

Once the exements arx designed as shxwn in Fig. 1 and Fig. 2, the elements are held in a mold such that part of the base is exposed. The mo...
