The invention discloses a satellite load active thermal control device. Belongs to the technical field of spaceflight loads and particularly relates to the technical field of satellite load active thermal control. The problems that an existing satellite load active thermal control device is long in development period and high in cost due to the fact that a microcontroller is used are solved. The device comprises a control circuit, a plurality of driving circuits and a plurality of external parts, the number of the driving circuits is the same as that of the external parts, the control circuit provides reference voltage representing a temperature threshold for the driving circuits, the driving circuits collect the temperature of a controlled device through the external parts, the external parts convert the temperature of the controlled device into feedback voltage, and the feedback voltage is used for outputting the feedback voltage. And the driving circuit controls the work of the external component by comparing the reference voltage with the feedback voltage, and feeds back the feedback voltage to the control circuit. The system has the advantages of simple control interface and low power consumption; a microcontroller and a software code are not included, and the reliability advantage is obvious; a software designer does not need to participate in research and development, and the research and development period and research and development difficulty can be remarkably reduced.
