The application discloses a spacecraft-oriented radiator design method and system, and belongs to the technical field of spacecraft thermal control. In order to solve the problems of non-uniform area and aperture, inaccurate extreme condition identification and lack of cross-validation in the prior art, the method comprises the following steps: obtaining an orbit and a radiator parameter; calculating an orbit position, a solar vector and an eclipse; independently calculating five types of external heat flow sub-items of a solar direct radiation, an earth albedo, an earth infrared, a deep space radiation and an earth radiation on a front surface and a back surface of the radiator, and summing up to obtain a total net heat flow density; according to a solving mode, a first mode of inversely solving a radiator area with a fixed temperature constraint is executed, or a second mode of inversely solving a balance temperature with a fixed area is executed; and finally, energy closure diagnosis and sub-item conservation checking are performed. Through double-sided sub-item modeling, reciprocal solving and three-stage extreme condition searching, the application realizes the improvement of design accuracy, the reduction of calculation cost and the quantitative evaluation of model self-consistency, and is suitable for the thermal control design of various low earth orbit spacecrafts.
