Abstract
Multiple oscillating heat spreaders (OHS) were fabricated for the purpose of effectively transporting heat fluxes from vehicular electronics. The OHSs possessed modified evaporators for enhanced thermal spreading capabilities; one OHS was designed for pressure shorting, i.e. the ‘Slots OHS’, and the other for thermal shorting, i.e. the ‘Perforated Evaporator OHS’. These OHSs were tested in the axial heating configuration with the evaporator length-wise opposite the condenser, as well as in a centralized heating configuration implemented with the condenser thick-wise opposite the heat source to characterize thermal spreading effectiveness. The condensing location and heat input were varied in the central heating and axial configuration to determine thermal spreading effectiveness dependency to condenser location, heat removal, and heat input. Both OHSs were experimentally compared to an OHS of similar dimensions with no modified evaporator, and the results indicate the modified evaporators improve OHS thermal spreading ability for high heat flux thermal management.
