Abstract
Abstract The disclosure describes a method of attachment of a corrugated wire mesh having a plurality of wire bends to a substrate. In the method, flats are formed at the bends, and the flats are lightly coated with a thermosetting adhesive. And in a subsequent clamping operation, the adhesive is displaced from the interface of contact between the wire and substrate, thereby displacing the adhesive to the adjacent interstices. This leaves the mesh and substrate in direct thermal contact without a distinct layer of adhesive separating them.

Claims Analysis

Claim 1
Independent Claim
166 words
The process of making a heat sink by attaching a corrugated wire mesh to a heat dissipating surface using a thermosetting adhesive, wherein the wire mesh comprises a woven web of wire, each wire having a generally circular cross section and forming a plurality of bends; cleaning those surfaces of the bend portion forming the mesh which comes in contact with the heat dissipating surface and the corresponding mating area of the dissipating surface which defines the interface area of the mesh; forming a slight flat on the contact area of the mesh whereby the flat is parallel to the heat dissipating surface; dispensing a small amount of adhesive on the cleaned interfaces; assembling the components and clamping them together such that the adhesive is largely displaced and squeezed out from the mesh interface and deposited in the mesh intersticies leaving the mesh wire bend and the mating area of the heat source in good thermal contact and curing the clamped assembly in a suitable oven.
