Abstract
Official abstract text for this publication.
In one embodiment, a heat conducting composite material may include a bulk material, a conduit, and a conduit material. The bulk material forms a shaped body having a heat introduction portion and a heat dissipation portion. The conduit is disposed in the bulk material and connects the heat introduction portion to the heat dissipation portion. The conduit material is disposed within and fills the conduit. The bulk material thermal conductivity of the bulk material is about equal to a conduit material thermal conductivity of the conduit material at a first temperature. The bulk material thermal conductivity is less than or equal to the conduit material thermal conductivity throughout a first temperature range. The bulk material thermal conductivity is greater than or equal to the conduit material thermal conductivity throughout a second temperature range.
First claim

What is claimed is: 1. A system for transferring heat, the system comprising: a heat conducting composite material comprising a bulk material forming a shaped body having a heat introduction portion and a heat dissipation portion; a conduit disposed in the bulk material and connecting the heat introduction portion to the heat dissipation portion; and a conduit material disposed within and filling the conduit, wherein: the conduit material has a different composition than the bulk material; the thermal conductivity of the bulk material is temperature dependent and the thermal conductivity of the conduit material is temperature dependent; the thermal conductivity of the bulk material is equal to the thermal conductivity of the conduit material at an activation temperature; and the thermal conductivity of the bulk material is less than or equal to the thermal conductivity of the conduit material throughout an activation temperature range; and a heat generating device in thermal communication with the heat introduction portion of the heat conducting composite material, wherein the heat generating device operates at an operating temperature that is within the activation temperature range, and wherein the melting point of the bulk material and the melting point of the conduit material are above the operating temperature of the heat generating device such that the bulk material is solid and the conduit material is solid. 2. The system for transferring heat of claim 1 , further comprising a heat sink in thermal communication with the heat dissipation portion of the heat conducting composite material and a cooling fluid. 3. The system for transferring heat of claim 1 , wherein the thermal conductivity of the bulk material is greater than the thermal conductivity of the conduit material throughout a deactivation temperature range. 4. The system for transferring heat of claim 3 , wherein the deactivation temperature range comprises higher temperatures than the activation temperature. 5. The system for transferring heat of claim 3 , wherein the deactivation temperature range comprises lower temperatures than the activation temperature. 6. The system for transferring heat of claim 1 , wherein the thermal conductivity of the conduit material is equal to at least two times the thermal conductivity of the bulk material at one temperature in the activation temperature range.
