[0008] The present invention relates generally to portable temperature-controlled storage systems, and more particularly to cooling chamber assemblies and thermal interface architectures that use PP-homopolymer insulation structures and hydrocarbon-coated aluminum thermal interfaces to control heat transfer between a payload chamber and a heat extraction subsystem.Background

[0009] Temperature-sensitive materials used in medical, biological, and pharmaceutical contexts require stable temperature maintenance during storage and transport. Portable systems that attempt to provide active temperature control under battery power encounter technical constraints associated with heat leakage, limited thermal mass, and limited heat extraction capacity within compact form factors. Conventional compressor-driven systems often impose size, weight, and power requirements that are difficult to accommodate in portable use cases, while passive systems relying on ice packs or gel packs tend to exhibit uncontrolled thermal profiles, temperature drift, and limited ability to maintain a narrow target temperature range.

[0010] Portable cooling systems also face persistent thermal-path inefficiencies at interfaces between a payload chamber and a cooling element. In compact assemblies, localized coupling at a small contact region frequently produces non-uniform heat extraction, resulting in internal temperature gradients and extended equilibration times. These gradients are exacerbated when the payload chamber is surrounded by polymer housings that introduce discontinuities in thermal conduction, or when insulation structures require penetrations, fasteners, or seams that create preferential leakage paths.

[0011] Additional technical challenges arise from material selection and interface management. ABS and similar polymers are commonly used as enclosure materials due to cost and manufacturability, but these materials can impose unfavorable thermal leakage behavior, mechanical deformation at sealing interfaces, and compatibility constraints with layered assemblies. Systems using multi-layer structures often require gasketed interfaces to manage sealing and assembly tolerances, and inconsistent gasket compression or thickness variation can degrade both sealing reliability and thermal repeatability. Further, thermal interface surfaces that are not engineered for controlled heat absorption and redistribution can exhibit hot spots and unstable temperature control behavior under transient load conditions, including lid opening events, ambient temperature swings, or varying payload thermal mass.

[0012] Accordingly, a need exists for a portable temperature-controlled architecture that improves thermal isolation while enabling efficient and uniform heat transfer from a payload chamber to a heat extraction subsystem. A further need exists for a layered assembly architecture that provides repeatable mechanical integration, reliable sealing, and predictable thermal pathways using materials and surface treatments that support controlled heat absorption and redistribution. A further need exists for a configuration that reduces localized thermal gradients by shaping thermal spreading through interface geometry and mounting orientation, while remaining manufacturable within compact portable form factors.BRIEF SUMMARY OF THE INVENTION

[0032] Example definitions for some embodiments are now provided.

[0033] Acrylonitrile butadiene styrene (ABS) is a common plastic polymer.

[0034] High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum.

[0035] Phase change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa. Example PCM materials can include, inter alia: organic (paraffin and nonparaffin), inorganic (salt hydrates and metallic alloys), and eutectic (mixture of two or more PCM components: organic, inorganic, and both).

[0036] Polypropylene (PP) is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.

[0037] Press fit or friction fit is a fastening between two parts which is achieved by friction after the parts are pushed together, rather than by any other means of fastening.

[0038] Temperature sensors can include mechanical temperature sensors, electrical temperature sensors, integrated circuit sensors, medometers, etc.

[0039] Thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.

[0040] Thermal control material (TCM) is a substance capable of storing and releasing thermal energy to regulate temperature. It is noted that TCM can include phase change materials (PCM) such as paraffins, salt hydrates, and eutectic mixtures, thermal mass materials such as water or glycol solutions, and other heat storage media. TCM can include: Phase change materials (PCM) that store energy through phase transitions (e.g., paraffins, salt hydrates, eutectic mixtures); Sensible heat storage materials that store energy through temperature change (e.g., water, glycol solutions, mineral oils, molten salts); Solid thermal mass materials providing thermal inertia (e.g., concrete, ceramic, stone, sand); Metallic thermal buffers with high conductivity (e.g., aluminum heat sinks, copper spreaders, graphite plates, metal foam); and Composite thermal materials combining multiple thermal management functions (e.g., metal matrix composites, polymer-PCM encapsulations, graphene-enhanced compounds).Example Smart Refrigerator Exterior Views

[0055] The top-loading configuration represents a significant advancement in portable temperature-controlled storage, combining innovative solid-state cooling technology with thermal management and monitoring systems. The design achieves exceptional efficiency and reliability while maintaining precise temperature control across varied environmental conditions.

[0056] More specifically, FIG. 1 is a top view of example embodiment of a portable temperature-controlled enclosure 100, according to some embodiments. FIGS. 2 and 3 are isometric views of example embodiment of a portable temperature-controlled enclosure 100, according to some embodiments. FIG. 4 is a front view of example embodiment of a portable temperature-controlled enclosure 100, according to some embodiments. FIG. 5 is a side view of example embodiment of a portable temperature-controlled enclosure 100, according to some embodiments.

[0057] In one embodiments, portable temperature-controlled enclosure 100 can have a top-loading configuration with example payload dimensions: 3.2″×4.1″×5.5″. An example top opening capacity can be one (1) liter. Overall dimensions, by way of example, can be 107.78 mm×119.92 mm×166.84 mm. Portable temperature-controlled enclosure 100 provides a top access lid for payload (e.g. medications, etc.) insertion.

[0058] FIG. 6-9 illustrate various example views of an aluminum cooling chamber portable unit 200, according to some embodiments. Aluminum cooling chamber portable unit 200 can be the internal cooling / heating system of portable temperature-controlled enclosure 100.

[0059] Aluminum cooling chamber portable unit 200 of portable temperature-controlled enclosure 100 comprises a thermoelectric cooling mechanism wherein electrical power is transmitted through a strategically positioned semiconductor chip 202 mounted at a calculated angular orientation relative to the aluminum payload chamber 204. The semiconductor chip 202 incorporates a material combination wherein electrons traverse between different semiconductor elements, creating an energy absorption effect at the material junction interfaces. This energy absorption phenomenon, occurring at the precise locations where the material composition transitions, facilitates the cooling process through electron mobility differentials between the semiconductor materials.

[0060] The thermal management system utilizes direct thermal coupling between the semiconductor chip 202 and an aluminum payload chamber 204, whereby the energy absorption at the material junctions actively extracts heat from the payload area through the aluminum wall interface. The extracted thermal energy is subsequently transferred to a closed-loop cooling system 206 comprising fluid-carrying pipes 208 directly coupled to the posterior surface of the semiconductor chip (e.g. can include a heat sink system). The cooling loop 206 employs either water or antifreeze as the working fluid, circulating through an engineered pipe network via an integrated pump mechanism.

[0061] The system's thermal circuit can be completed through a fan-assisted heat exchanger configuration 214, wherein the heated working fluid from the cooling loop 206 is actively cooled before being recirculated through the system. The angular mounting of the semiconductor chip, deliberately oriented at a calculated angle rather than perpendicular to the payload chamber, achieves enhanced cooling distribution by optimizing the radius of coolness spread and increasing the effective surface area coverage. This angular configuration demonstrably improves the speed and uniformity of temperature distribution compared to traditional perpendicular mounting arrangements.

[0062] The thermal control system can operate in a dual-power configuration, initially utilizing wall power for the cooldown phase until the target temperature (typically 2° C.) is achieved, at which point the system transitions to battery power through a lithium polymer battery assembly capable of maintaining temperature control for 72 hours of autonomous operation. The internal configuration includes various top-loading variants (e.g. via top opening 212, etc.) while maintaining identical operational principles, with the semiconductor chip positioning optimized for each configuration to maximize cooling efficiency through enhanced radial distribution patterns.

[0063] The angular orientation of the semiconductor chip 202 relative to the payload chamber wall facilitates superior thermal spreading characteristics. The cooling effect disperses in a radial pattern rather than traditional linear distribution, resulting in more efficient coverage of the payload surface area and accelerated temperature equalization throughout the chamber. This geometric optimization of the semiconductor chip 202 placement enables the system to achieve more comprehensive thermal coverage compared to conventional perpendicular mounting configurations, as the angular positioning creates an expanded radius of cooling influence that enhances the overall heat absorption efficiency of the system.

The top-loading portable temperature-controlled enclosure 100 includes a Data Management module 1110 for continuous temperature logging and location tracking and recording.

[0069] Additional information on chip positioning is now discussed. The innovative cooling system centers around a precisely engineered 40 mm×40 mm semiconductor chip that represents a significant advancement in portable refrigeration technology. This chip, comprising multiple semiconductor junctions arranged in an optimized pattern, is mounted at a carefully calculated 20-degree angle relative to the payload chamber wall, deviating from traditional perpendicular mounting approaches. This specific angular orientation was chosen to maximize the cooling efficiency through enhanced radial distribution patterns.

[0070] The mounting configuration creates a thermal management system where the chip interfaces directly with the aluminum chamber wall for maximum thermal conductivity. This direct coupling is maintained by a spring-loaded mechanism that ensures a consistent 30-40 PSI mounting pressure, crucial for optimal heat transfer. The interface between the chip and wall utilizes a high thermal conductivity compound with carefully controlled thickness and verified full surface coverage.

[0071] The 20-degree mounting angle serves a critical purpose in the system's operation. Unlike conventional perpendicular mounting, which typically results in linear cooling distribution, this angular orientation creates an expanded radius of cooling influence. This radial distribution pattern enables more comprehensive coverage of the payload surface area and facilitates faster temperature equalization throughout the chamber. The result is a more efficient and effective cooling system that achieves superior thermal coverage compared to traditional mounting configurations.

[0072] In the top-loaded configuration, the chip is positioned lower, near the midsection of the wall, with the temperature sensor strategically placed inside the payload wall towards the bottom side. This positioning was specifically chosen to optimize the cooling effect in relation to the temperature sensor location. The entire setup demonstrates a carefully engineered approach to thermal management, where each component's position has been optimized for maximum efficiency.

[0073] The semiconductor chip's design and mounting create a cooling effect that disperses in a radial pattern rather than a traditional linear distribution. This radial dispersion is particularly effective because it provides more uniform coverage across the payload area. The angular mounting effectively increases the total area over which the cooling effect spreads, resulting in more efficient temperature control throughout the chamber. This innovative approach to chip mounting and cooling distribution represents a significant advancement in portable refrigeration technology, offering improved performance over conventional perpendicular mounting systems.

[0074] The system's overall design reflects a deep understanding of thermal dynamics and practical engineering considerations. By combining the precise 40 mm×40 mm chip dimensions with the 20-degree mounting angle and strategic positioning relative to temperature sensors, the system achieves optimal cooling performance while maintaining efficient use of space within the portable unit. The careful attention to mounting pressure, thermal compound application, and interface design ensures reliable and consistent performance, making this cooling system particularly well-suited for portable applications requiring precise temperature control.Material-Transition-Based Cooling Architecture with Angled Aluminum Thermal Interfaces and Polypropylene Homopolymer Insulation

[0075] In some embodiments, a cooling system is provided that implements a multi-material thermal management architecture incorporating a PP-homopolymer structural and insulating framework in combination with aluminum components coated with a hydrocarbon material. The cooling system represents an advancement in thermal management design through replacement of conventional ABS-based insulation with PP-homopolymer while preserving and enhancing core cooling functionality. The disclosed configuration demonstrates a materials-driven approach to thermal control in which insulation performance, structural integration, and thermal transfer efficiency are jointly optimized.

[0076] PP-homopolymer is a polypropylene material formed from a single propylene monomer through chain-growth polymerization, resulting in a substantially uniform polymer matrix. The PP-homopolymer exhibits enhanced thermal insulation properties, structural rigidity, chemical resistance, and manufacturability relative to copolymer, blended polymer, or ABS-based materials. In the disclosed cooling system, the PP-homopolymer provides lower thermal conductivity than ABS while maintaining mechanical stability, compatibility with layered thermal assemblies, gasketed interfaces, and fastener systems, and functional compatibility with adjacent aluminum thermal components and hydrocarbon-based thermal control materials.

[0077] In some embodiments, the cooling system includes a primary structural enclosure formed from PP-homopolymer material that functions as both a mechanical support structure and a thermal insulation layer. Internal components are arranged within the PP-homopolymer structure and include an aluminum core element having a hydrocarbon coating applied thereto, along with one or more silicon rubber gaskets configured to provide sealing and controlled thermal separation between adjacent components. The gaskets may be implemented with multiple thicknesses to accommodate differing mechanical and sealing requirements at distinct interface locations.

[0078] In some embodiments, a thermal interface assembly is provided that includes an aluminum plate coated with a hydrocarbon material and coupled to a precision-engineered fin structure. The fin structure is configured to increase effective surface area and promote efficient thermal transfer between the thermal interface assembly and an internal payload chamber. The hydrocarbon coating applied to the aluminum plate and fin structure is configured to function as a thermal control material (TCM) that facilitates heat absorption and redistribution while maintaining compatibility with the surrounding structural materials.

[0079] In some embodiments, the cooling system is constructed as a layered assembly comprising a top homopolymer plate coupled with a gasket system, an internal aluminum assembly including hydrocarbon-coated components, and an integrated fin structure positioned to define a directed thermal pathway. The gasket system may include primary gaskets of a first thickness and secondary gaskets of a reduced thickness at countersunk or localized fastening regions, thereby enabling controlled compression, sealing integrity, and thermal isolation across the assembly.

[0080] In some embodiments, thermal management performance is enhanced through an angled mounting configuration of a cooling block relative to the payload chamber. The cooling block may be mounted at an angle of approximately forty-five degrees with respect to a wall of the payload chamber, thereby promoting non-linear thermal spreading and improving distribution of cooling across the payload volume. The angled mounting configuration cooperates with the fin structure and hydrocarbon-coated thermal interface to define a strategic thermal pathway that accelerates temperature equalization within the chamber.

[0081] In some embodiments, the PP-homopolymer material provides enhanced thermal insulation properties relative to ABS while also serving as an integrated structural element capable of supporting internal aluminum assemblies and gasketed interfaces. The PP-homopolymer material is compatible with hydrocarbon coating processes applied to adjacent aluminum components and enables optimized thermal isolation between internal cooling elements and the external environment.

[0082] In some embodiments, the cooling system is assembled through a defined integration sequence that includes formation of an internal payload chamber having a hydrocarbon-coated surface, attachment of an aluminum fin structure treated with a hydrocarbon coating, placement of silicon rubber gaskets at defined interface locations, integration of the homopolymer outer enclosure, and installation of the angled cooling block. This sequence establishes a controlled thermal and mechanical interface network within the system.

[0083] In some embodiments, the complete cooling system integrates the angled cooling block, hydrocarbon-coated aluminum components, fin structures, gasket assemblies, and PP-homopolymer enclosure into a unified thermal control architecture. The configuration provides optimized insulation through homopolymer construction, enhanced thermal transfer through fin-based surface expansion, and controlled thermal pathways defined by material transitions and interface management.

[0084] In some embodiments, manufacturing considerations include application of the hydrocarbon coating through polymerization or copolymerization processes, precision placement of gaskets to ensure sealing and interface consistency, deliberate selection of material transition boundaries to manage thermal gradients, and controlled assembly of thermal interfaces to preserve surface contact quality. These considerations contribute to repeatable performance and manufacturability of the cooling system.

[0085] Collectively, the disclosed cooling system represents a material-centric advancement in thermal management technology through the coordinated use of PP-homopolymer insulation, hydrocarbon-coated aluminum thermal interfaces, fin-based heat transfer structures, and angled cooling block placement. The resulting architecture enables efficient and controlled thermal performance while maintaining structural robustness and manufacturability across a range of cooling applications.

[0086] FIG. 12 illustrates an isometric view of an example cooling chamber assembly 1200, according to one or more implementations. The cooling chamber assembly 1200 comprises a payload chamber formed as a generally rectangular enclosure defining an internal storage volume configured to receive temperature-sensitive contents. The payload chamber includes a top opening region 1204, the top opening region being configured to interface with a removable lid, sealing structure, or upper enclosure component to allow access to the internal storage volume while maintaining thermal isolation during operation.

[0087] The walls of the payload chamber are formed from a thermally conductive inner structure cooperatively integrated with an external insulating enclosure, such that the payload chamber defines a controlled thermal environment. The internal surfaces of the payload chamber are configured to cooperate with hydrocarbon-coated thermal control components to promote uniform temperature distribution within the internal volume.

[0088] A cooling interface plate 1202 is mounted to a side wall of the payload chamber at a non-orthogonal orientation relative to the vertical axis of the chamber. As shown, the cooling interface plate 1202 is positioned at an oblique angle, such as approximately forty-five degrees, relative to the chamber wall. The angled orientation of the cooling interface plate 1202 is selected to promote non-linear thermal spreading across the chamber wall and to accelerate temperature equalization within the payload chamber.

[0089] The cooling interface plate 1202 is configured to couple thermally with an external cooling block or heat extraction assembly positioned outside the payload chamber. Fastening apertures distributed around the perimeter of the cooling interface plate 1202 enable secure mechanical attachment while maintaining controlled thermal contact between the cooling interface plate and the external cooling block. The cooling interface plate may comprise an aluminum substrate coated with a hydrocarbon thermal control material, enabling efficient heat absorption and redistribution across the chamber wall.

[0090] The overall geometry illustrated in FIG. 12 demonstrates a payload chamber configuration in which angled thermal coupling, controlled interface placement, and enclosure geometry cooperate to define a strategic thermal pathway. This configuration improves cooling uniformity, reduces localized thermal gradients, and enhances overall thermal management performance relative to perpendicular or centrally mounted cooling interfaces.

[0091] FIG. 13 illustrates an exploded isometric view of a cooling chamber assembly 1300 showing the layered construction and component integration of the thermal management architecture, according to some embodiments. The assembly 1300 includes a payload chamber 1304 configured to define an internal storage volume for temperature-sensitive contents. The payload chamber 1304 is positioned at the upper portion of the assembly and is configured to interface with a top opening and sealing structure.

[0092] A top plate formed from PP-homopolymer material 1302 is positioned beneath the payload chamber 1304. The top plate 1302 functions as both a structural support element and a thermal insulation layer, providing mechanical stability while reducing thermal leakage between the payload chamber and underlying thermal components.

[0093] Positioned below the top plate 1302 is an aluminum thermal interface assembly 1306 comprising an aluminum plate coated with a hydrocarbon thermal control material and an integrated fin structure. The fin structure extends from the aluminum plate and defines a high-surface-area thermal transfer region configured to promote efficient heat absorption and redistribution. The hydrocarbon-coated aluminum components operate as a thermal control interface between the payload chamber, and a cooling block positioned externally to the payload chamber.

[0094] A cooling block interface region 1308 is shown coupled to the aluminum thermal interface assembly 1306. The cooling block interface region is configured to mechanically and thermally couple the internal thermal interface assembly to an external cooling block or heat extraction structure. Fastening features distributed across the interface enable secure attachment while maintaining controlled thermal contact.

[0095] The assembly further includes an external enclosure 1310 formed from PP-homopolymer material that surrounds the internal aluminum thermal components. The PP-homopolymer enclosure 1310 provides thermal insulation, structural containment, and environmental protection for the internal thermal pathway while supporting attachment of external components.

[0096] An angled interface opening 1312 is formed in a side wall of the external enclosure 1310. The angled interface opening 1312 is configured to receive a cooling interface plate mounted at a non-orthogonal orientation relative to the payload chamber wall. The angled configuration cooperates with the internal fin structure and hydrocarbon-coated aluminum components to promote non-linear thermal spreading and improved temperature uniformity within the payload chamber.

[0097] Collectively, FIG. 13 illustrates the layered assembly architecture in which a PP-homopolymer enclosure, hydrocarbon-coated aluminum thermal interfaces, fin-based surface expansion, gasketed interfaces, and angled thermal coupling cooperate to define a controlled thermal pathway from an external cooling block to the internal payload chamber.

[0098] Cooling chamber assembly 1300 is configured to integrate physically and functionally with semiconductor chip 202 and aluminum payload chamber 204 to form a continuous and directed thermal control pathway. The aluminum payload chamber 204 defines a thermally conductive enclosure for temperature-sensitive contents and is positioned in direct or near-direct thermal communication with cooling chamber assembly 1300 through one or more hydrocarbon-coated interface surfaces.

[0099] Physically, aluminum payload chamber 204 is coupled to the aluminum thermal interface assembly 1306 of cooling chamber assembly 1300 such that the aluminum structures cooperate as a unified conductive body. The mating surfaces between aluminum payload chamber 204 and the thermal interface assembly 1306 are configured to maintain controlled surface contact, optionally through the use of gasketed interfaces or compression mounting, to ensure repeatable thermal coupling while accommodating manufacturing tolerances and thermal expansion.

[0100] Semiconductor chip 202 is positioned adjacent to and in thermal communication with the aluminum thermal interface assembly 1306 through a mounting interface that maintains consistent contact pressure across the chip surface. The semiconductor chip 202 is mounted such that a first surface of the chip is thermally coupled to the hydrocarbon-coated aluminum plate of the thermal interface assembly 1306, while an opposing surface of the chip interfaces with a cooling block or heat extraction structure. This placement enables the semiconductor chip 202 to function as an active thermal transfer element between aluminum payload chamber 204 and the external heat extraction subsystem.

[0101] Functionally, heat absorbed by aluminum payload chamber 204 from the payload volume is conducted through the chamber walls to the hydrocarbon-coated aluminum thermal interface assembly 1306. The hydrocarbon thermal control material applied to the aluminum surfaces promotes heat absorption and lateral redistribution across the interface, while the integrated fin structure increases effective surface area and enhances thermal exchange with semiconductor chip 202.

[0102] The angled orientation of the cooling interface region associated with cooling chamber assembly 1300 positions semiconductor chip 202 at a non-orthogonal angle relative to aluminum payload chamber 204. This angled configuration promotes non-linear thermal spreading across the payload chamber wall, reduces localized thermal gradients, and accelerates temperature equalization within the payload chamber. The geometric relationship between semiconductor chip 202, the hydrocarbon-coated aluminum interface, and aluminum payload chamber 204 is selected to optimize thermal distribution rather than concentrating cooling at a single point.

[0103] During operation, thermal energy extracted from aluminum payload chamber 204 is transferred through the hydrocarbon-coated aluminum interface to semiconductor chip 202, which actively drives heat away from the payload chamber toward the external cooling block. The PP-homopolymer components of cooling chamber assembly 1300 cooperate with aluminum payload chamber 204 to thermally isolate this active thermal pathway from the surrounding enclosure, thereby maintaining controlled internal temperature conditions.

[0104] Through this integration, cooling chamber assembly 1300, semiconductor chip 202, and aluminum payload chamber 204 operate as a coordinated thermal control subsystem in which material selection, interface geometry, mounting orientation, and surface treatment jointly define efficient, repeatable, and uniform thermal management across multiple payload chamber embodiments.Additional Discussion

[0105] In some embodiments, the disclosed cooling system is not limited to a single chamber configuration, plate geometry, or enclosure structure, but instead comprises a parameterized thermal architecture configurable across multiple material selections, geometric forms, and heat-transfer arrangements. The invention contemplates a systematic design space in which thermal performance characteristics are achieved through coordinated variation of structural materials, surface topologies, cooling block architectures, and mounting geometries. Such variations are disclosed as interoperable embodiments within a common inventive framework rather than as isolated or ad hoc designs.

[0106] In certain embodiments, structural and insulating components of the cooling system can be formed from different polymeric and composite materials, including but not limited to acrylonitrile butadiene styrene (ABS), polypropylene homopolymer (PP-homopolymer), polymethyl methacrylate (PMMA), and composite materials comprising expanded polystyrene (EPS) foam combined with fiberglass reinforcement. Material selection can be tailored to achieve desired insulation performance, structural rigidity, manufacturability, and compatibility with adjacent thermally conductive elements.

[0107] In some embodiments, the payload chamber and associated thermal interfaces can assume a variety of geometric configurations, including rectangular, cylindrical, pyramidal, ribbed, pocketed, or asymmetric forms. These geometries are not merely aesthetic, but are mechanically and thermally determined to influence heat flow paths, surface-area-to-volume ratios, weight reduction, and thermal equilibration behavior. In certain embodiments, non-symmetrical shapes, recessed pockets, ribs, or apertures are incorporated to reduce mass while preserving or enhancing thermal conductivity and structural integrity.

[0108] In some embodiments, heat-transfer surfaces within the cooling system can include flat plates, finned plates, pin-based arrays, pyramidal fin structures, or surfaces treated by abrasive or sand-blasting processes to increase effective surface area. These surface topologies can be selectively applied to payload walls, intermediate thermal plates, or cooling block interfaces to enhance heat absorption and thermal spreading characteristics.

[0109] In certain embodiments, the cooling system includes one or more cooling blocks configured to extract heat from a thermoelectric cooling element. The cooling block architecture can vary and may include aluminum-based blocks, copper-based blocks, or combinations thereof. In some embodiments, a single cooling block is employed, while in other embodiments multiple cooling blocks are used in parallel or distributed configurations. In further embodiments, the cooling block includes internal fluid channels populated with fins or pins, wherein a circulating coolant is driven by a pump to transport heat away from the cooling element. Such internal structures may include a high density of micro-fins or micro-pins to increase surface area, with design tradeoffs between thermal performance, coolant flow resistance, pump load, system weight, and cooling speed.

[0110] In some embodiments, mounting strategies for the thermoelectric cooling element and associated cooling block can vary. The cooling element and cooling block may be mounted substantially perpendicular to a payload wall or at a non-perpendicular angle, such as approximately 20 degrees, 40 degrees, or 45 degrees relative to the payload wall. Angled mounting configurations can be selected to promote radial thermal spreading, accelerate temperature equalization, and improve uniform cooling of the payload chamber as compared to linear heat flow associated with perpendicular mounting.

[0111] In some embodiments, the thermal interfaces of the payload chamber, fin structures, pin structures, and cooling plates are coated with a hydrocarbon material. The hydrocarbon coating is described generically in figures and structural depictions, while specific hydrocarbon compositions may be disclosed in the written description. The coating can be applied via polymerization or copolymerization processes and may be deposited on aluminum or other thermally conductive substrates. The hydrocarbon coating functions as a thermal interface material that both absorbs heat and facilitates transmission of cooling from the thermoelectric element to the payload chamber. By defining the coating in terms of a functional class of hydrocarbons rather than a single chemical species, the invention supports broad applicability and enablement across multiple coating compositions.

[0112] In certain embodiments, PP-homopolymer is used as an insulating or structural material in place of ABS. The use of PP-homopolymer can provide improved thermal insulation characteristics, enhanced compatibility with hydrocarbon coating processes, and improved integration with aluminum core assemblies. Additionally, PP-homopolymer can offer manufacturability advantages in layered assemblies employing gaskets, fasteners, or press-fit interfaces, thereby supporting alternative embodiments disclosed herein.

[0113] In some embodiments, the geometry of the payload chamber and associated cooling structures is explicitly selected based on mechanical and thermal calculations rather than aesthetic considerations. Certain regions of the chamber may be designed to cool earlier than others in order to accelerate overall thermal equilibrium within the payload volume. Such geometry-driven cooling behavior can reduce total cooldown time, improve temperature uniformity, and enhance system efficiency. These characteristics support utility-level enablement and provide a technical basis for distinguishing the disclosed configurations from designs that rely on uniform or purely symmetric chamber geometries.

[0114] In some embodiments, the disclosed cooling system is best understood as a collection of interacting subsystems, including a hydrocarbon-coated thermal interface subsystem, a payload chamber geometry subsystem, a cooling block heat extraction subsystem, an insulation and enclosure material subsystem, and an angular placement and thermal spreading subsystem. Embodiments may be defined as families characterized by parameter ranges rather than fixed dimensions or materials, and various levels of specificity may be provided depending on whether the disclosure is directed to provisional embodiments or utility-level implementations. PP-homopolymer-based embodiments are disclosed as primary embodiments within this system architecture rather than as secondary or optional variants.

[0115] Cooling chamber assembly 1300 is configured for physical and functional integration within portable temperature-controlled enclosure 100 to define a unified thermal control system. The cooling chamber assembly 1300 is dimensioned and shaped to be received within an internal cavity of portable temperature-controlled enclosure 100 such that the payload chamber 1304 is positioned in thermal communication with external cooling components while remaining thermally insulated from the external environment.

[0116] Physically, the PP-homopolymer enclosure 1310 of cooling chamber assembly 1300 interfaces with corresponding structural features of portable temperature-controlled enclosure 100 to provide mechanical support, alignment, and vibration resistance. The homopolymer enclosure 1310 cooperates with the enclosure walls of portable temperature-controlled enclosure 100 to form a nested insulation architecture in which thermal leakage paths are minimized through layered material transitions. Mechanical fasteners, interference fits, or gasketed interfaces may be used to secure the cooling chamber assembly 1300 within enclosure 100 while preserving controlled thermal separation between internal and external components.

[0117] Functionally, the aluminum thermal interface assembly 1306 and the angled cooling interface region 1312 of cooling chamber assembly 1300 are positioned to align with a corresponding cooling block or heat extraction subsystem mounted within portable temperature-controlled enclosure 100. The angled orientation of the cooling interface enables efficient thermal coupling between the internal hydrocarbon-coated aluminum components of cooling chamber assembly 1300 and the external cooling block, establishing a directed thermal pathway from the payload chamber 1304 to the heat extraction subsystem.

[0118] During operation, heat absorbed from the payload chamber 1304 is transferred through the hydrocarbon thermal control material applied to the aluminum thermal interface assembly 1306 and distributed across the fin structure to increase effective surface area. The transferred heat is then conveyed through the angled interface region 1312 to the cooling block integrated within portable temperature-controlled enclosure 100, where the heat is removed from the system. The PP-homopolymer enclosure 1310 and the surrounding structure of enclosure 100 cooperate to thermally isolate this heat transfer pathway from the external environment, thereby maintaining a stable internal temperature.

[0119] The integration of cooling chamber assembly 1300 within portable temperature-controlled enclosure 100 further enables modularity and scalability of the thermal system. Cooling chamber assembly 1300 may be installed, removed, or replaced as a discrete unit while maintaining compatibility with the enclosure architecture and cooling block interface of enclosure 100. This modular integration supports multiple payload sizes, cooling capacities, and enclosure form factors without requiring redesign of the core thermal pathway.

[0120] Through this physical and functional integration, cooling chamber assembly 1300 and portable temperature-controlled enclosure 100 operate as a coordinated thermal management system in which material selection, geometry, interface orientation, and insulation strategy jointly define controlled thermal performance, improved temperature uniformity, and reduced thermal losses during portable operation.

[0122] In some embodiments, the PP-homopolymer enclosure defines a directionally biased thermal barrier, wherein wall thickness, rib geometry, and polymer flow orientation during molding are selected to reduce thermal leakage along undesired heat paths while preserving mechanical rigidity.

[0123] In some embodiments, the aluminum thermal interface assembly is arranged such that no continuous metallic conduction path exists between the internal thermal pathway and the external enclosure, except through hydrocarbon-coated interface surfaces, thereby forcing heat transfer to follow a defined and controlled thermal pathway.

[0124] In some embodiments, the hydrocarbon coating applied to aluminum surfaces functions as a thermal interface material that reduces interfacial thermal resistance between adjacent components while maintaining mechanical adhesion and stability under repeated thermal cycling.

[0125] In some embodiments, the hydrocarbon coating exhibits phase-stable behavior across the operating temperature range of the cooling system, maintaining substantially consistent thermal conductivity, surface wetting, and adhesion properties during active cooling, maintenance cooling, and passive thermal retention states.

[0126] In some embodiments, the fin structure integrated into the aluminum thermal interface assembly is configured with non-uniform fin spacing, fin height, or fin thickness, such that lateral thermal spreading is promoted prior to heat extraction by an adjacent cooling element.

[0127] In some embodiments, the fin structure is oriented such that at least a portion of the fins are non-parallel to a primary heat flux direction, thereby increasing effective surface interaction and improving thermal exchange efficiency at the cooling interface.

[0128] In some embodiments, the angled orientation of the cooling interface plate relative to the payload chamber wall is selected to generate asymmetric thermal gradients that promote non-linear thermal spreading across the chamber wall and accelerate temperature equalization within the payload chamber.

[0129] In some embodiments, the angled cooling interface plate defines a projected thermal coupling footprint that spans multiple internal convection regions within the payload chamber, reducing localized cooling concentration and improving temperature uniformity.

[0130] In some embodiments, the cooling system is configured such that thermal spreading within the payload chamber precedes active heat extraction, thereby distinguishing the system from point-source cooling architectures that extract heat directly from a single orthogonal interface.

[0131] In some embodiments, the PP-homopolymer enclosure includes thermally isolating standoff regions positioned adjacent to the aluminum thermal interface assembly, preventing parasitic heat loss into the enclosure structure while maintaining mechanical support.

[0132] In some embodiments, gasket elements positioned between adjacent components comprise elastomeric materials selected with differing thicknesses or durometer values, enabling controlled compression, sealing integrity, and accommodation of thermal expansion mismatch between polymeric and metallic components.

[0133] In some embodiments, the gasket system functions as a mechanical compliance layer that preserves consistent thermal contact pressure across aluminum interface surfaces while reducing mechanical stress during thermal cycling.

[0134] In some embodiments, the cooling system is configured to operate in a passive thermal retention mode when active cooling is disabled, wherein the PP-homopolymer enclosure and hydrocarbon-coated aluminum surfaces cooperate to slow thermal ingress into the payload chamber.

[0135] In some embodiments, the cooling system transitions between active cooling, maintenance cooling, and passive thermal retention states without mechanical reconfiguration of internal components.

[0136] In some embodiments, the payload chamber geometry includes localized variations in wall thickness or surface topology positioned relative to the angled cooling interface plate to influence internal thermal circulation patterns and cooling uniformity.

[0137] In some embodiments, the aluminum payload chamber and the aluminum thermal interface assembly are manufactured as independently optimized components, enabling adjustment of payload volume, surface area, or thermal interface characteristics without redesign of the external enclosure.

[0138] In some embodiments, the cooling system is scalable such that thermal interface assemblies having different fin densities, plate thicknesses, or hydrocarbon coating compositions may be substituted while maintaining compatibility with the PP-homopolymer enclosure.

[0139] In some embodiments, the cooling chamber assembly is configured as a modular and replaceable thermal unit capable of installation, removal, or replacement without disassembly of the surrounding enclosure structure.

[0140] In some embodiments, the cooling system architecture enables multiple thermal coupling locations at different orientations or positions relative to the payload chamber, providing distributed thermal pathways and reducing reliance on a single cooling interface.

[0141] In some embodiments, structural load paths defined by the PP-homopolymer enclosure are intentionally decoupled from thermal load paths defined by the aluminum thermal interface assembly, thereby improving mechanical durability without degrading thermal performance.

[0142] In some embodiments, the cooling system exhibits improved coefficient of performance relative to orthogonally mounted cooling interface architectures due to reduced thermal resistance and enhanced thermal spreading efficiency.

[0143] In some embodiments, the PP-homopolymer enclosure functions as a dielectric thermal isolation barrier, enabling safe integration with electrically active cooling elements and associated control electronics.

[0144] In some embodiments, the cooling system is configured for portable, battery-powered operation, wherein improved thermal efficiency directly reduces energy consumption and extends operational duration.

[0145] In some embodiments, the disclosed cooling system defines a materials-directed thermal architecture in which thermal behavior is governed primarily by controlled material transitions and interface geometries rather than bulk insulation thickness alone.

[0146] In some embodiments, the cooling system is configured to maintain substantially uniform internal temperature distribution under dynamic external temperature conditions, including transient exposure to elevated ambient environments.

[0147] In some embodiments, the cooling system is suitable for transport and storage of temperature-sensitive medical, pharmaceutical, biological, or semiconductor payloads requiring repeatable and uniform thermal control.CONCLUSION
