Coolant heat exchanger intended for heat removal by radiation into an open space is considered. The settlement program for numerical calculating the fin-type heat exchanger is described. Various emitter panel constructions are analyzed. Identical versions of radiant panels with neon and hydrogen as the heat carrier are compared. Comparative characteristics data of the matrix radiator for heat carriers with different combination of materials and pipes edges are shown. Advantages of liquid metal heat carrier of the intermediate circuit are underlined. Main features and packaging problems of power installation of a space plant are named. Version of the radiator design with a phased scheme of its opening in orbit is proposed
