Spacecraft with heat dissipators mounted on thermally coupled shelves

A spacecraft, comprising;

• a first radiator panel which defines a first surface which radiates into space, and which includes at least a first elongated heat pipe thermally coupled to said first surface, said first radiator panel also defining a second surface, at least a portion of which is thermally coupled to said first heat pipe, whereby heat coupled to said first heat pipe from said second surface is transferred to said first surface and radiated into space;
• a heat-dissipating first load coupled to said second surface, whereby its heat is coupled to said first heat pipe, and conveyed to said first surface of said first radiator panel, for radiation thereby;
• a shelf;
• shelf mounting means mechanically coupled to said shelf and to said first radiator panel, for mounting said shelf so that it extends parallel to said first radiator panel at a predetermined distance from said second surface thereof, at a location interior to said spacecraft, whereby a broad side of said shelf cannot radiate toward space;
• a bent second heat pipe, including a first portion extending along, and thermally coupled to, said shelf, said heat pipe also including a second portion extending parallel to, in close proximity, and thermally coupled to, a portion of said first heat pipe, said second heat pipe also including an elongated third portion extending between said first and second portions of said second heat pipe;
• a heat-dissipating second load coupled to a surface of said shelf, in thermal communication with said first portion of said second heat pipe, whereby said second heat pipe carries heat dissipated by said second load to said portion of said first heat pipe, which in turn carries said heat from said second heat pipe to said first surface of said radiator panel.
