THERMOACOUSTIC RADIATOR

摘要

FIELD: physics.SUBSTANCE: radiator contains a heat-conducting substrate on the working surface of which the parallel extended structures in the form of ledges of prismatic shape are formed which have alloyed surface layers with considerably larger electric conductivity, than the substrate. The extended structures are connected to the conducting contact areas formed on the substrate. Surfaces of the substrate and the heat-emitting structures are covered from above with a nanodimensional layer of silicon dioxide.EFFECT: improvement of reliability, specific acoustic power and maximum frequencies of radiated acoustic oscillations.1 dwg
