The invention relates to the technical field of satellite load thermal balance tests, in particular to a thermal control device for a satellite load vacuum thermal balance test. The heat isolation cabin is mounted above the supporting assembly; the heat dissipation assembly comprises a heat dissipation plate arranged on one side plate of the heat isolation cabin, a first heat rapid transfer assembly connected with the heat dissipation plate and the heat isolation cabin, and a first heater arranged on the heat dissipation plate; the heat compensation assembly comprises a second heat rapid transfer assembly and a second heater arranged on the side plate, away from the heat dissipation plate, of the heat isolation cabin; and a program-controlled temperature acquisition system. The device provided by the invention can simulate all working conditions of a satellite load in an in-orbit space environment, can realize conversion of different working conditions without opening the tank, reduces air pumping and deflation of the vacuum tank, saves the satellite load heat balance test time, does not need frequent disassembly and assembly in the test process, and improves the test efficiency. And the risk caused by frequent disassembly and assembly to the satellite load is reduced.
