A method of forming a phase change passive heat sink, with a base member and heat dissipating members, is provided. The base member is hollow and defines an evaporation chamber therein. A number of heat dissipating members are connected to the base member. Each of the heat dissipating members are substantially tubular in configuration with a closed end and an open end and defining respective condensation chambers therein. The open ends of the heat dissipating members are connected to the base member with the condensation chambers and are in fluid communication with the evaporation chamber. A heat transporting media resides in the base member which is movable into the condensation chambers upon application of heat to the base member. Heat is dissipated through the heat dissipating members.

[ What is claimed is:] [1.]1. A method of forming a phase change heat sink assembly, comprising the steps of:forming a wick frame having a hollow base, with an base chamber, and a plurality of hollow upstanding members, with respective upstanding member chambers; said base chamber being in fluid communication with said upstanding member chambers;placing said wick frame into a mold;overmolding an outer housing of moldable thermally conductive polymer material around said hollow base and said hollow upstanding members of said wick frame; said outer housing formed around said hollow base being an evaporation region and said outer housing formed around said upstanding members being respective condensation chambers;forming a load hole through said outer housing and said hollow base;introducing heat transporting media through said load hole into said hollow base; andsealing said load hole thereby trapping said heat transporting media within said outer housing.
