Abstract
An ultrasonic atomizer for maintaining a constant temperature of an ultrasonic vibration generating unit by decreasing a temperature at the periphery of the ultrasonic vibration generating unit even under an environment in which the ultrasonic vibration generating unit is exposed to a high temperature is provided. The ultrasonic atomizer includes: an ultrasonic vibration generating unit which generates ultrasonic waves and atomizes a spray material; a nozzle unit; a housing; and a heat exchange unit which surrounds the ultrasonic vibration generating unit, includes a separation wall which divides the heat exchange unit into heat exchange chambers, and cools heat generated from the ultrasonic vibration generating unit, in which the heat exchange chambers include: a heating chamber; and a cooling chamber which surrounds the heating chamber, and includes a cooling space by being isolated with the heat exchange unit abutting the heating chamber between the cooling chamber and the heating chamber.
