Abstract:
1. A cooling apparatus for removing heat from at least one heat generating component, said cooling apparatus comprising: a low profile metal unitary member comprised of one piece of metal, said low profile unitary member having a first exterior surface adapted for receiving heat from the at least one heat generating component and having a plurality of micro tubes formed of said one piece of metal having a flattened heat transfer surface, said low profile metal unitary member having a micro tube inlet comprised of said one piece of metal and a micro tube outlet comprised of said one piece of metal, said low profile metal unitary member providing an entirely metallic thermal path for conducting heat from said first exterior surface to a heat transfer fluid contained within said plurality of micro tubes, said plurality of micro tubes being formed along an axis relative to said low profile unitary member; an inlet tube; cavitied inlet end cap interconnecting the micro tube inlets in fluid communication and connecting the micro tube inlets in fluid communication with said inlet tube, said cavitied inlet end cap having a width equal to a width of the low profile metal unitary member; an outlet tube; cavitied outlet end cap interconnecting the micro tube outlets in fluid communication and connecting the micro tube outlet in fluid communication with said outlet tube; each of said plurality of microtubes being fluidly connected to adjacent and non-adjacent microtubes via said inlet end cap and said outlet end cap, said cavitied outlet end cap having a width equal to the width of the low profile metal unitary member; means for circulating said heat transfer fluid through said inlet tube, said inlet end cap, the plurality of micro tubes of said low profile metal unitary member, said outlet end cap, and said outlet tube in a manner such that said fluid is injected into and ejected from said low profile unitary member parallel to said axis of said micro tubes; and means for removing heat from said heat transfer fluid.
