The invention discloses a conical rotating test piece external heat flow simulation system suitable for a thermal vacuum test. The system comprises an external heat flow simulation infrared lamp arraystructure, a rotary table, a bottom platform car and a control system, wherein a conical rotating test piece is fixed to the working face of the rotary table, the rotary table is fixed to the bottomplatform car, the bottom platform car is arranged on a guide rail, and the rotary table control system sets the rotating speed to enable the test piece to rotate according to the set working condition; the external heat flow simulation infrared lamp array is a conical lamp array, is installed on the bottom platform car and surrounds the side face of the conical test piece; and the control system sets the radiation power of the lamp array and simulates solar radiation borne by the test piece on the rail. The system is suitable for the vacuum thermal test of the conical rotating test piece.
