Abstract :
THE liberal use of vacuum tubes in toll transmission equipment, the miniaturization of this and other component apparatus, and the assembly of the components into cubic units rather than on flat panels, for the purpose of realizing the potential space saving, has presented a new problem in heat dissipation. The necessity of designing for safe heat disposal has long been recognized in radio transmitters and similar high-power equipment. Now it is apparent in low-power equipment as well.
