A satellite load heat dissipation system comprises a gear pump and is further provided with an automatic valve, a comparison circuit and a control circuit. Heat dissipation coil pipes are installed on heat dissipation faces of parts needing heat dissipation in the satellite platform, a heat dissipation agent box is installed on a feeding pipe of the gear pump, a discharging pipe of the gear pump is connected with one ends of the heat dissipation coil pipes respectively, and the other ends of the heat dissipation coil pipes are connected with the heat dissipation agent box in parallel. The automatic valve comprises a valve body, a valve core, an electromagnetic coil, an armature and a force sensitive resistor which are mounted together; an inlet pipe and an outlet pipe of the automatic valve are connected in series among the plurality of heat dissipation coil pipes; the comparison circuit comprises a thermistor and an output sub-circuit, and the thermistor is arranged on the heating surface of each component; the output sub-circuit and the control circuit are installed in a satellite platform and are electrically connected with the force sensitive resistor and the thermistor. The heat dissipation device is compact in structure, light in weight and beneficial to being carried on a satellite platform, effectively dissipates heat for corresponding parts, and meanwhile can prevent the situation that the working performance of special parts is reduced due to too large heat dissipation amount.
