Designing a Thermal Radiation Oven for Smart Phone Panels

Abstract

Thermal radiation is the only heat transfer mechanism with vacuum compatibility, and it carries energy at light speed. These advantages are taken in this work to design an oven for smart phone panels. The temperature of panels is acquired from a numerical method based on finite-difference method. The space configuration of the heating lamps as well as the relative distance between lamps and the panel are control factors for optimization. Full-factorial experiments are employed to identify the main effects from each factor. A fitness function Q considering both temperature uniformity of the panel and the heating capability of the ovens is proposed. The best oven among 27 candidates is able to raise panel temperature significantly with high uniformity.

Thermal Model and Countermeasures for Future Smart Glasses

“…For recognition and interface, techniques have been presented for head gestures [11], face detection [12], eye movements [13], user authentication [14], estimation of respiration rate [15], speech interaction with eye blinking detection [16], context-aware lightning control [17], distance learning [18], and indoor localization [19], drowsiness and fatigue detection to increase road safety [20], countermeasures to phishing attacks [21], gait aid for Parkinson's disease patients [22], contextually-aware learning in physics experiments [23], and guiding for visually impaired users [24]. Some techniques regarding thermals have been presented such as 3D thermal model reconstruction based on image-based modeling using smartphone sensors [25], design of an oven utilizing radiative heat transfer for smart phone panels [26], thermal management systems for civil aircraft engines [27], and thermal properties of glasses [28]. A system for low-power smart glasses has been presented [29].…”

Heat Transfer and Its Innovative Applications

“…The fifth paper [5] describes the optimization of an oven utilizing radiative heat transfer as the single heat mechanism for smart phone panels. Optimization using full-factorial experiments to identify the main effects from each factor such as space configuration of the heating lamps and the relative distance between lamps and the panel is proposed.…”
