Novel thermal management of electronic devices by nano enhanced phase change materials: A numerical study
Bibliographic record
Abstract
Efficient and effective thermal management is considered essential for electronic devices as increased power densities generate substantial heat, risking performance and longevity. This study numerically analyzed nano-enhanced phase change materials (NPCMs) integrated with optimized heat sink designs for electronic cooling. Solid-solid PCMs (S-S PCMs) were augmented with nanoparticles to improve thermal conductivity, and a novel heat sink geometry was developed using the Solid Isotropic Material with Penalization (SIMP) topology optimization method. The optimization study identified an optimum Helmholtz radius of 8 × 10 −4 m and a hyperbolic projection slope (β) of 6, achieving uniform temperature distribution and efficient phase transitions. The topology-optimized design reduced chip and heat sink temperatures by 2.65 °C and 3.51 °C, respectively, compared to the baseline model, while nanoparticle enhancement alone in Model 2 achieved reductions of 1.64 °C and 2.54 °C. A grid independence analysis and experimental validation confirmed model accuracy with an average deviation of 3 %. This study therefore brings an optimized heat sink design utilizing topology optimization to create compact cooling solutions for high-power density electronics. • The study proposed a unique optimized heat sink configuration for electronic chip cooling. • The performance of developed heat sink is analyzed and compared to baseline models. • Results show superior performance of proposed design couple with S-S NPCMs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
