Abstract

Abstract

The analytical expression of the temperature rise of the heat sink of a diode laser array has been obtained by solving the heat conduction equation. The influence of convection heat transfer coefficient on the temperature rise of the top and the bottom surfaces has been analyzed. The temperature difference between the top and the bottom changes little when the convection heat transfer coefficient reaches certain value. The temperature rise decreases as the convection heat transfer coefficient increases. All of the results obtained are in accordance with that by the finite element method and confirmed by the experiment.
