20100186938 | HEAT TRANSFER SHEET AND HEAT DISSIPATION STRUCTURE - A heat transfer sheet of the present invention includes a heat transfer layer having a first portion and a second portion provided in a position different from the first portion in a planar view of the heat transfer layer, the second portion being capable of expanding and contracting in a thickness direction of the heat transfer layer at an expansion ratio larger than that of the first portion depending on temperature changes in an object from which heat is to be dissipated. In a state that the heat transfer sheet is used, in the case where a temperature of the heat transfer layer is a predetermined temperature or lower, thermal conductivity between the object and a dissipation member is lowered due to creation of a gap between the second portion and the object and/or the dissipation member, whereas in the case where the temperature of the heat transfer layer is a predetermined temperature or higher, the thermal conductivity between the object and the dissipation member is increased due to substantial elimination of the gap. | 07-29-2010 |
