Design of a Cylindrical Jet Impingement Cooling System for High-Power Common-Mode Choke in Aerospace Applications
Bibliographic record
Abstract
With the increasing demand for efficient, power-dense, and reliable power systems in aerospace applications, the thermal management of high-power electronic components has become a critical challenge. High-power common-mode chokes, essential components for electromagnetic interference (EMI) suppression, generate significant heat during operation, necessitating effective cooling techniques to maintain optimal performance and prolong their lifespan. This paper presents the design of a novel cylindrical jet impingement cooling system specifically tailored for high-power common-mode chokes in aerospace applications. The proposed cooling system leverages the advantages of jet impingement cooling to achieve enhanced heat transfer and temperature uniformity across the magnetic core as well as the bus bar while offering a competitive mass reduction compared to similar devices. A cylindrical configuration is chosen to accommodate the geometric constraints of the magnetic core and bus bar configuration used in such applications. Mathematical modelling in partnership with computational fluid dynamics (CFD) simulations is employed to evaluate the thermal as well as pressure drop performance of the system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
