Provided is an ultrasonic atomizer capable of maintaining a set temperature of an ultrasonic vibration generation unit even in an environment in which same is exposed to high temperatures by cooling the temperature in the periphery thereof. The ultrasonic atomizer comprises: an ultrasonic vibration generation unit for generating ultrasonic waves and atomizing spray material; a nozzle unit comprising a spray fluid passageway through which the spray material moves along the central axis penetrating the center of the ultrasonic vibration generation unit, and a nozzle tip for receiving the spray material from one end of the spray fluid passageway and spraying the spray material through the other end of the spray fluid passageway; a heat-exchange unit, surrounding the ultrasonic vibration generation unit, for cooling the heat generated from the ultrasonic vibration generation unit; and a housing surrounding the ultrasonic vibration generation unit and the heat-exchange unit and having a plurality of heat-exchange chambers in the interior thereof, wherein the plurality of heat-exchange chambers comprise: a vortex chamber, located in the periphery of the ultrasonic vibration generation unit in the interior of the housing, for guiding the flow of a vortex flow; and an insulation chamber surrounding the vortex chamber, having a barrier in contact therewith, and comprising an inner insulating space. |
