Core assembly for coil units and method for producing the same |
摘要 |
A core assembly for coil units and a method for producing the same which can suppress a raise of temperature are provided. A secondary core (21) made of a ferrite includes a pair of core members (25, 25) which are symmetrical with respect to each other and are adapted to be coupled to each other. Each core member (25) is provided in its coupling surface (44) with a groove (43). When the core members (25, 25) are coupled to each other, the integrated grooves (43, 43) define a flow path (40) adapted to flow a cooling medium in the secondary core (21). Thus, it is possible to form a flow path in a core made of a sintered material which is too hard to be worked. <IMAGE> |
