Capillary-stabilized solid-state heat extraction architecture

A thermoelectric heat pipe thermal management system comprising:

• a plurality of cooling plates arranged in a spatially distributed configuration, each cooling plate comprising a thermally conductive base structure;
• a plurality of thermal interface pads, wherein each cooling plate incorporates at least two thermal interface pads dimensioned to receive thermoelectric modules, said thermal interface pads configured to establish thermal contact between thermoelectric module surfaces and the cooling plate base structure;
• a plurality of solid-state thermoelectric modules having configurable semiconductor pellet densities, each thermoelectric module comprising bismuth telluride semiconductor pellets interconnected by electrically conductive traces and disposed between ceramic substrate plates, wherein the thermoelectric modules are configured to generate cold zones at first surfaces and hot zones at second surfaces when electrical current is applied;
• a plurality of heat pipes, each heat pipe comprising a sealed tubular structure containing an internal wick structure and a working fluid configured to undergo phase-change thermal transport, wherein each heat pipe comprises an evaporator section thermally coupled to at least one cooling plate and a condenser section thermally coupled to a radiator assembly, and wherein each heat pipe further comprises a dual-offset geometric configuration comprising a lateral bend along the pipe length and a shift at the radiator connection point;
• a radiator assembly comprising a plurality of radiator sections arranged with uniform center-to-center spacing, each radiator section configured to receive heat pipe condenser sections at staggered connection points and to dissipate thermal energy through forced convection cooling;
• wherein the evaporator section of each heat pipe is positioned to receive heat from the hot zones of thermoelectric modules through the thermal interface pads and cooling plate base structure, causing the working fluid to undergo phase transition from liquid to vapor;
• wherein vapor generated at the evaporator section travels through the heat pipes to the radiator assembly condenser sections via pressure differential, where forced convection causes vapor condensation back to liquid phase, and wherein condensed liquid returns to the evaporator section to complete a continuous thermodynamic cycle without external pumping;
• wherein each cooling plate with its associated thermal interface pads and heat pipes functions as an independent thermal management module enabling modular scalability;
• and
• wherein the spatial distribution of the plurality of cooling plates enables simultaneous multi-zone cooling with inherent redundancy such that degradation or failure of one module does not compromise thermal management capability of remaining modules.
