Structural thermal codesign of hydrocarbon functionalized metallic chambers for directed heat management

A cooling chamber for a portable temperature-controlled enclosure, comprising

• a payload chamber defining an interior volume configured to receive temperature-sensitive contents, the payload chamber comprising an aluminum structural wall having a hydrocarbon-based thermal control medium bonded thereto such that the aluminum structural wall functions both as a load-bearing element and as an active thermal interface;
• a conductive grill structure positioned adjacent to the payload chamber, the conductive grill structure comprising aluminum having the hydrocarbon-based thermal control medium bonded thereto, the conductive grill structure being configured to redistribute heat laterally across a surface area greater than that of the payload chamber wall;
• a heat extraction coupling interface thermally coupled to the payload chamber and the conductive grill structure, the heat extraction coupling interface being configured to conduct heat away from the payload chamber along a defined thermal pathway;
• a metallic heat extraction block thermally coupled to the heat extraction coupling interface, the metallic heat extraction block being formed from a material having higher thermal conductivity than the aluminum structural wall and being configured to passively spread and stabilize heat received from the payload chamber;
• and
• a polymeric thermal isolation enclosure surrounding the payload chamber, the conductive grill structure, and the heat extraction coupling interface, the polymeric thermal isolation enclosure being configured to limit parasitic heat exchange with an external environment,
• wherein the payload chamber, conductive grill structure, heat extraction coupling interface, metallic heat extraction block, and polymeric thermal isolation enclosure cooperate to establish a layered and directional thermal pathway for regulating temperature within the interior volume.
