PURPOSE:To permit efficient reduction of heat, generated from a power board, by a method wherein the conductors of a main circuit in the power board are formed by super conductive materials and the other apparatuses are cooled by cool air, obtained from the cooling liquid of the superconductive materials. CONSTITUTION:The conductors 10 of a main circuit in a power board 1 and the other circuits, which belong to the main circuit, are formed by superconductive materials. Cooling liquid 30, supplied from a cooling unit 2 for cooling the superconductive materials, is made to flow through a cooling pipe 40 in the board, which is arranged in the power board 1. Apparatuses 11 in the power board are cooled by the excessive cooling air, obtained from the cooling liquid for cooling the superconductive materials. According to this method, the amount of heat, generated in the power board 1, may be reduced. |
