Abstract

PURPOSE:To increase the input of a printing apparatus to a large extent by a method wherein heat generated in a drive coil is transported to the outside of a printing part by a heat pipe or the like and heat removal is sharply increased by forcedly cooling in other end part of the heat pipe or the like by a fan. CONSTITUTION:Heat generated in a drive coil 4 is passed through a wall of a sealed container 13 and, thereafter, transmitted to a porous substance 14 and a liquid in the porous substance is evaporated by receiving said heat and a generated vapor is passed through a vapor passage encircled by the porous substance 14 to be moved toward other end thereof. The vapor is cooled and liquefied by discharging condensation heat and, after the condensation heat is passed through the porous substance 14 and the sealed container 13, heat removal is carried out by air sent in by a fan 16 through a fin 15.
