HIGH THERMAL CONDUCTIVITY INSULATING MEMBER AND ITS MANUFACTURING METHOD, ELECTROMAGNETIC COIL, AND ELECTROMAGNETIC DEVICE

摘要

A tape- or sheet-shaped high thermal conductivity insulating member, its manufacturing method, an electromagnetic coil comprising the high thermal conductivity insulating member, and an electromagnetic device such as a power generator having the electromagnetic coil. It is necessary to improve the cooling performance of an electromagnetic coil of an electric device so as to enhance the efficiency and to reduce the size and manufacturing cost. For the enhancement, it has been tried to increase the thermal conductivity of a tape- or sheet-shaped insulating member of the electromagnetic coil. However, there have been problems that the thermal conductivity of conventional insulating members has been insufficient, and only special resin components can be used. To solve the above problems, according to the invention, the tape- or sheet-shaped insulating member is made of a material such that first particles having a thermal conductivity of 1 to 300 W/mK and second particles having a thermal conductivity of 0.5 to 300 W/mK are dispersed in a resin base.
