Abstract
A cooling device for a robot controller includes a servo driver having a circuit board and a heat generation element. The cooling device includes a fin member which is attached to the heat generation element, a temperature sensor, a heat conductive sheet which transmits heat generated in the heat generation element to the temperature sensor, a fan which generates an air flow toward the fin member, and a fan control part which controls the fan based on a detection value of the temperature sensor. The heat conductive sheet is disposed between the circuit board and the heat generation element in the servo driver and is contacted with both of the circuit board and the heat generation element, and the temperature sensor is provided on the circuit board and is covered by the heat conductive sheet.
