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 shaft 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 housing surrounding the ultrasonic vibration generation unit and having a plurality of heat-exchange chambers therein; and a heat-exchange unit, surrounding the ultrasonic vibration generation unit and comprising a barrier for separating the plurality of heat-exchange chambers, for cooling the heat generated by the ultrasonic vibration generation unit, and wherein the plurality of heat-exchange chambers comprise: a heating chamber, located in the periphery of the ultrasonic vibration generation unit in the interior of the housing, comprising a heating space; and a cooling chamber surrounding the heating chamber and distanced therefrom with the heat-exchange unit, which is in contact with the heating chamber, therebetween, and comprising a cooling space. |
