A Novel Integrated Multi-Layer Cooling (IMLC) Structure for High Power Density Applications
Bibliographic record
Abstract
This paper proposes a new Integrated Multi-Layer Cooling (IMLC) thermomechanical structure for high power density applications. The IMLC structure includes three design objectives to maximize thermal performance while optimizing power density. First, multiple PCBs are stacked vertically to increase PCB surface area. Second, cold plate liquid cooling is integrated onto the bottom most PCB to increase heat transfer. Third, components are distributed based on heat generation to efficiently cool lossy components. PCB thermal resistances are estimated based on three dimensional orthogonal thermal conductivities. FEA based thermal simulation is conducted with single PCB design and two-layer IMLC design. A 1.3kW power converter prototype is constructed with a single-layer PCB design using integrated liquid cooling. In testing, efficiency is improved by 0.6% and high loss component temperature rise is decreased by 50% compared to an air-cooled design. A two-layer IMLC design achieves the same thermal performance while improving power density by 31%.

How this classification was reachedexpand
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.
