For the planned communication spacecraft 'Arcomsat', a heat pipe radiator had been designed, manufactured and tested successfully. The north - and south panel of the 'Arcomsat' is provided with electronic components such as TWT's, EPC's and amplifiers. Heat due to energy losses are dissipated directly into these panels which radiate the energy to space. The main dissipation energy is produced by two amplifiers, located in a relatively small area. The dissipation heat of these two amplifiers should be distributed nearly isothermal over the whole radiator surface with about 1,7 m(sup2) (1,3 m x 1,5 m). The weight of the complete radiator is limited to about 4,3 kg. Heat pipes, integrated in the honeycomb core of the radiator panel had been selected for this energy distribution.
