The development of a Modular Radiator System is described. Applications of these modules are imaginable at geostationary satellites for thermal control of electronic components, or at Spacelab pallets for experiment cooling. In order to be able to offer suitable modules for a wide range of different requirements of space applications three different types of heat pipe radiators were developed, a fixed conductance radiator, and two variable conductance radiators one passively controlled and one actively controlled. The lay-out calculations were performed with existing computer programs. The final design was derived following a detailed parametric study dealing with the influencing factors. The manufactured radiators were tested in a space simulation chamber. The influence of heat input variation, solar radiation and solar eclipse was evaluated during this test. To conclude the tests, a vibration test was performed with the fixed conductance radiator and the passively controlled, variable conductance radiator. Results are presented for calculated and tested performance.
