Heat dissipating apparatus for use in dissipating heat produced by electronic components of a spacecraft. The heat dissipating apparatus comprises first and second radiator panels each having an outer panel faceskin 18 and inner panel faceskin. A heat pipe matrix is disposed between outer and inner panel faceskins of each radiator panel, and a honeycomb core is disposed between the inner and outer panel faceskins that surrounds the heat pipe matrix. A transverse panel interconnects the first and second radiator panels. A plurality of crossing heat pipes extend between and thermally couple to the heat pipe matrices of the first and second radiator panels. The plurality of crossing heat pipes extend outside the plane of the transverse panel.
