A heat dissipating member which is disposed between a heat generating electronic component which when operated generates heat and reaches a temperature higher than room temperature and a heat dissipating component is characterized in that the heat dissipating member is non-fluid in a room temperature state prior to operation of the electronic component and acquires a low viscosity, softens or melts under heat generation during operation of the electronic component to fluidize at least a surface thereof so as to fill between the electronic component and the heat dissipating component without leaving any substantial voids, and the heat dissipating member is formed of a composition comprising a silicone resin and a heat conductive filler.
摘要:
An electromagnetic wave absorbing heat conductive composition is used to form an electromagnetic wave absorbing heat dissipating article that is placed between a heat generating electronic component which, when operated, generates heat, reaches a temperature higher than room temperature and acts as an electromagnetic wave generating source, and a heat dissipating component. The composition is non-fluid at room temperature prior to operation of the electronic component, but acquires a low viscosity, softens or melts under heat generation during operation of the electronic component, to fluidize at least a surface of the composition so that the composition substantially fills any gaps between the electronic component and the heat-dissipating component.

A heat-softening heat-radiation sheet including a polyolefin-based heat-conductive composition which comprises a polyolefin and a heat-conductive filler, has a softening point of 40° C. or above, has a thermal conductivity of 1.0 W/mK or higher, has a viscosity at 80° C. of from 1×102 to 1×105 Pa·s and has a plasticity at 25° C. in the range of from 100 to 700. This heat-radiation sheet which is in the form of a solid sheet at room temperature, can readily be attached to or detached from electronic components and a heat sink, is capable of softening by the heat generated during operation of electronic components, to have the interfacial contact thermal resistance at a negligible level, and has a superior heat-radiation performance.
