Material-conditioned cylindrical thermal flux regulation system with radially distributed conduction geometry

A portable temperature-controlled enclosure, comprising:

• a cylindrical housing;
• a payload chamber disposed within the cylindrical housing;
• a cooling chamber thermally coupled to the payload chamber, the cooling chamber comprising anodized aluminum having a hydrocarbon surface treatment comprising tetradecane;
• a thermoelectric module thermally coupled to a wall portion of the cooling chamber through a thermal interface material;
• a controlled-force mounting assembly configured to apply a mounting force to the thermoelectric module to maintain thermal contact at the thermal interface material;
• a heat rejection assembly thermally coupled to a hot-side of the thermoelectric module, the heat rejection assembly comprising a liquid-cooled cooling block defining internal coolant pathways;
• a pump configured to circulate a coolant through the internal coolant pathways;
• at least one temperature sensor configured to measure a temperature associated with the payload chamber;
• and
• a controller configured to drive the thermoelectric module and the pump based on the temperature measured by the at least one temperature sensor to maintain the payload chamber within a target temperature band.
