Abstract

PURPOSE:To spontaneously convey heat generated by mutual connection of conductors to the low temperature side so as to uniformalize temperature and to reduce the size of an enclosed switchboard by housing a heat conducting unit such as a heat pipe in a conductor accompanied by partial heat, and providing the conductor with heat radiation fins. CONSTITUTION:When partial heat occurs in a contact 6 of an enclosed switchboard, the heat is conveyed to a conductor 1-a, namely to a heat medium 9 built in the conductor 1-a, which medium 9 is turned into vapor 10. The partial heat generated at the contact 6 is taken, and thereafter the vapor 10 flows to the low temperature side to introduce the partial heat to the heat radiation fins 13. The partial heat is then taken by a heat coveying unit (heat pipe) arranged inside of the conductors 1-a, 1-b, 1-c, and the heat is spontaneously conveyed to the low temperature side as vapor and radiated to the outside by the heat radiation fins 13.
