PURPOSE:To cool heat generating sections in a core uniformly and efficiently by arranging porous dispersing members for dispersing a refrigerant in a liquid phase into interspaces formed in the laminating direction of the core. CONSTITUTION:When a refrigerant 5 in a liquid phase is supplied to an upper section of a main body 12 from feed pipe 7 and fed to the interspaces 11 of a core 10 from a conduit 13, the refrigerant 5 is supplied to each dispersing member 14 contacting with the core 10 and dispersed by the capillarity of the porous members. The refrigerant 5 is phase-changed into a refrigerant 15 in a gaseous phase by evaporation over a wide range in the heat generating sections of the core 10, passes through the interspaces of each dispersing member 14 and is evaporated. The inside of the core 10 of an electromagnetic induction apparatus is cooled by latent heat in case of the evaporation. The dispersing members 14 are formed by a porous material having affinity with the refrigerant 5. |
