Thermal Energy Transfer Channel Unit Cells for Faster Optimization

The patent divides the thermal energy transfer channel into discrete unit cells that can be independently optimized. Each unit cell represents a small segment of the overall channel, allowing the optimization process to focus on local topology variations rather than the entire channel structure. This segmentation enables efficient computational processing while maintaining design thoroughness through systematic exploration of unit cell configurations.

The patent applies local quality by optimizing the topology of individual unit cells with specific local characteristics rather than applying uniform optimization across the entire channel. Each unit cell can have customized internal geometry, material distribution, and flow path configurations tailored to local thermal and flow requirements, improving overall channel performance without requiring exhaustive global optimization.

By segmenting the complex geometry into standardized unit cells, the patent makes manufacturing more feasible. Each unit cell can be manufactured as a modular component using additive manufacturing or other advanced fabrication techniques, and then assembled into the complete thermal channel. This modular approach maintains the thermal efficiency benefits of complex geometries while improving manufacturability through standardization and modularity.

The patent utilizes parameter changes by systematically varying geometric parameters within unit cells (such as wall thickness, pore size, flow channel dimensions) to achieve optimal thermal performance. These parameter variations are constrained within manufacturable ranges and can be precisely controlled through modern manufacturing processes like stereolithography or selective laser melting, balancing thermal efficiency with ease of manufacture.

The patent segments the optimization problem into independent unit cell optimizations rather than optimizing the entire channel topology at once. This reduces the computational domain size and the number of design variables, significantly lowering the computational resources required. The thermal performance is maintained by ensuring that the optimized unit cells, when assembled, create an effective thermal pathway throughout the complete channel structure.

The patent merges the optimization results of multiple identical or varied unit cells to create the complete thermal channel design. By combining the optimized characteristics of individual unit cells through repetition and arrangement, the overall thermal performance is achieved without requiring exhaustive optimization of every point in the continuous channel geometry, thus reducing computational resource requirements.

By segmenting the design into reusable unit cells, the patent enables rapid development and iteration. Once a unit cell is optimized and validated, it can be quickly replicated and assembled into complete channel designs for different applications. This modular approach dramatically accelerates the development cycle compared to traditional methods that require re-optimizing entire channel geometries for each new design iteration.

The patent applies preliminary action by performing the computationally intensive topology optimization on a single representative unit cell in advance. This pre-optimized unit cell serves as a building block that can be rapidly deployed in various channel configurations without requiring repeated full-channel optimization, thus enabling fast development and iteration while managing optimization complexity effectively.
