Solid structures for thermal management

摘要

Solid structures for thermal management are provided. In one aspect, the solid structures can comprise a metal-ceramic composite member assembled to be in thermal contact with a heat source. The metal-ceramic composite member can be mechanically coupled to an assembly (e.g., an electronic assembly) containing the heat source, and can provide mechanical stability to such assembly. In another aspect, the solid structures can comprise an oxide member that covers a surface of the metal-ceramic composite member, forming a metal-ceramic-oxide interface at the surface. The thickness of the oxide member combined with the magnitude of its thermal conductivity relative to the thermal conductivity of the metal-ceramic composite member can permit heat transport substantially along a direction substantially parallel to the metal-ceramic-oxide interface, and can reduce heat transfer through such interface.

1. A solid structure for thermal management, comprising:
a metal-ceramic composite member comprising a spreader plate coupled to a housing of an electronic assembly and assembled to be in thermal contact with a heat source contained in the electronic assembly, the metal-ceramic composite member has a substantially planar surface and a first thermal conductivity, wherein the substantially planar surface extends entirely from a first edge of the metal-ceramic composite member to a second edge, opposite the first edge, of the metal-ceramic composite member, and wherein the substantially planar surface further extends entirely from a third edge of the metal-ceramic composite member to a fourth edge, opposite the third edge, of the metal-ceramic composite member; and a metal oxide layer assembled to form an interface with the metal-ceramic composite member at the substantially planar surface and having a second thermal conductivity, the first thermal conductivity is greater than the second thermal conductivity, whereby the solid structure transports heat from the heat source substantially along a direction substantially parallel to the interface.
