Hydrocarbon-functionalized aluminum fin lattice for controlled thermal flux distribution

A stacked thermal-transfer subassembly for a compact temperature-controlled system, comprising:

• a payload chamber defining a payload-facing thermal boundary;
• a Hydrocarbon-Functionalized Aluminum Fin Lattice for Controlled Thermal Flux Distribution having an aluminum base structure with a plurality of fins extending from a first surface and a generally planar mounting surface formed on an opposing second surface, the fin plate being positioned adjacent to the payload-facing thermal boundary;
• a solid-state cooling chip thermally coupled to the planar mounting surface of the Hydrocarbon-Functionalized Aluminum Fin Lattice for Controlled Thermal Flux Distribution on a non-payload-facing side thereof;
• and
• a heat dissipation structure thermally coupled to an opposing side of the solid-state cooling chip, wherein the Hydrocarbon-Functionalized Aluminum Fin Lattice for Controlled Thermal Flux Distribution is interposed between the payload chamber and the solid-state cooling chip and defines a controlled thermal interface configured to:
• (i) transmit cooling generated by the solid-state cooling chip into the payload chamber during active cooling operation,
• (ii) (absorb and redistribute heat from the payload chamber and adjacent internal structures during transient or reduced cooling operation, and
• (iii) moderate thermal gradients within the payload chamber through fin-mediated surface area expansion and surface-modified thermal interaction, such that heat flow within the system is regulated through the Hydrocarbon-Functionalized Aluminum Fin Lattice for Controlled Thermal Flux Distribution rather than by direct coupling between the solid-state cooling chip and the payload chamber.
