The effect of orientation on U-shaped grooved and sintered wick heat pipes
Bibliographic record
Abstract
The thermal management system for a compact sealed computer is studied here. The system consists of two heat spreaders that are connected by two U-shaped heat pipes. The heat pipes are used to transport the heat directly from the chipset to the finned case wall where it is dissipated to the ambient by natural convection. In this study, the effect of orientation on the performance of the U shaped heat pipe was determined. Temperature difference and thermal resistance were measured for a range of heat load values ranging from 0 W to 45 W per heat pipe. Heat pipes with an eccentric sintered wick structure and with an axial groove wick structure were tested. The orientation was found to have a significant effect on the axial groove wick heat pipe performance with a much smaller effect on the sintered wick heat pipe performance. The experimental results were in good agreement with that predicted from the basic governing equations of heat pipes.

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.
