Electronic device cooling assembly and method employing elastic support material holding a plurality of thermally conductive pins

摘要

An electronic device cooling assembly and fabrication method are provided which include a manifold with an orifice for injecting a cooling liquid onto a surface to be cooled, and an elastic pin support material with an opening aligned to the orifice of the manifold. Multiple thermally conductive pins are mounted within the support material, extending therefrom, and are sized to physically contact the surface to be cooled. The support material has a thickness and compliance which facilitates thermal interfacing of the pins to the surface by allowing second ends thereof to move vertically and tilt. The second end of each pin has a planar surface which is normal to an axis of the pin, and the support material facilitates the planar surfaces of the second pin ends establishing planar contact with the surface to be cooled, notwithstanding that the surface may be other than planar.
