The invention discloses a method for calculating the operating temperature of a loop heat pipe space radiation radiator system. The method comprises the steps that 1, all parts of a loop heat pipe and structural parameters of all the parts are obtained; 2, based on the structure parameters, the preset value of the steady-state operation temperature of the loop heat pipe and the first evaporation mass flow rate are obtained; 3, according to the first evaporation mass flow, the steam outlet temperature and the steam flowing pressure drop in the loop heat pipe are obtained; 4, constructing a coupling iteration model based on the steam outlet temperature and the flowing pressure drop; 5, according to the output result of the coupling iteration model, the heat leakage amount and the supercooling amount in the loop heat pipe are obtained; and 6, whether the heat leakage amount is equal to the supercooling amount or not is judged, and calculation of the operating temperature of the system in the loop heat pipe is co
