。 In an amplifier heat dissipation device that forcibly moves air within a cabinet using a fan rotated by a motor, a temperature detection element is brought into contact with a heat dissipation plate on which a power transistor is attached;
It consists of a voltage-controlled oscillation circuit that is controlled by a detection voltage corresponding to the temperature detected by the temperature detection element, and a motor drive circuit that controls the rotation of the motor in response to the output of the voltage-controlled oscillation circuit. When the temperature of the board is low, the fan rotation speed decreases,
Further, the heat dissipation device for an amplifier is characterized in that the number of rotations of the fan is changed in accordance with the temperature so that the number of rotations of the fan increases when the temperature of the heat sink is high.
