Abstract

A method of manufacturing a net-shape moldable U-shaped heat sink assembly includes injection molding a thermally conductive polymer composite material. The method includes forming a heat sink assembly base member with a number of integrated fins members thereon. A right upstanding wall extends from a first side of the base member and a left upstanding wall extends from a second side of the base member to form a substantially U-shaped heat sink assembly. To enhance thermal conductivity, fins members may be integrally formed into the base member, right wall and/or left wall during the molding of the heat sink assembly. Also, a flexible metallic substrate or hinges may be embedded within the U-shaped heat sink assembly to permit positioning of the right wall and left wall relative to the base member for custom configuration of the heat sink assembly.

Claims2

Dependent claims

A method of manufacturing an array of net-shape molded heat sink assemblies, comprising:

providing a first heat generating object having a top surface;
providing a second heat generating object positioned adjacently to said first heat generating object having a top surface;
net-shape molding a first substantially U-shaped heat sink assembly having a base portion and left and right wall upwardly extending from opposing edges of said base portion defining a first channel;
integrally connecting said right wall of said first substantially U-shaped heat sink assembly to said base portion at a first angle;
positioning said base portion of said first substantially U-shaped heat sink assembly on said top surface of said first heat generating object;
net-shape molding a second substantially U-shaped heat sink assembly having a base portion and left and right wall upwardly extending from opposing edges of said base portion defining a second channel;
integrally connecting said right wall of said second substantially U-shaped heat sink assembly to said base portion at a second angle;
said second angle being different than said first angle;
positioning said base portion of said second substantially U-shaped net shape molded heat sink assembly on said top surface of said second heat generating object;
and
aligning said first channel with said second channel.
